Basic operating skills 1. Master the basic skills of locksmiths; 2. Master Locksmith

Use of common tools and measuring tools; 3. Can independently complete the locksmith work; 4. Have the ability to disassemble and assemble simple parts independently; 5. Have the skills of clamping and drilling independently on the drilling machine.

In the practice of locksmith, we know that the main contents of locksmith are scraping, drilling, tapping, sawing, filing, assembly and marking; Understand the structure, classification, selection, filing posture, filing method and quality inspection of archives. First of all, we must get the right gear. It is the key to keep the file moving in a straight line when filing the plane. There are two kinds of filing force: horizontal thrust and vertical pressure. When pushing the file forward, the front hand pressure gradually decreases, and then it decreases when pushing the file to the middle position, and the pressure on both hands is the same. When pushing the file forward, the front hand pressure gradually decreases and then increases. No pressure is applied when the file is returned. This will make it easier for us to file. Then scrape, grind, drill, hinge, tap and so on. Although it is not very standard, it is the crystallization of our sweat and the result of our two-day struggle.

To tell the truth, locksmith internship is boring. He may have been doing it all morning, but he is repeating an action. He still needs strength, and he needs to do it properly. That is, he took the file back and forth on the workpiece. By noon, his hands were sore and his legs were stiff. However, when he is tired, he can see the teacher personally guiding and demonstrating. He is also sweating and panting. A few days later, looking at my own processing results, I want to say thank you to the teacher who guided us. Turning is not done by numerical control, it requires high manual operation ability. Before the fitter, I knew that the fitter was hell. Students from other majors have already told me about the hardships of survival of the fittest. And many people regard the broken saw blade as a joke. So I want to win in the middle. When I went there, I was beaten by the master (that is, the master told you that locksmiths are suffering, and everyone should be mentally prepared, and so on).

In particular, you are not allowed to go back to using the milling machine! ) and a long group (because there are two people missing in my class, the master has added 20% more time), and we started to work! The first is to saw a piece of iron! Although I was instructed by the master, I was the first person to break the saw blade! And the boys in the same group have already spoken. Depressed! But it doesn't matter. The teacher said nothing to me! Thank god. Maybe I am too unprofessional with the boys in the same group, and we have sawed off several groups, and we are still less than half. However, with my encouragement, the boys in the same group saw the iron instead of the last one. It's good. Followed by scribing and drilling. It's nothing. Because teachers and machines do more. There is nothing special about Tao. The only thing that doesn't suit us is that there is a barbed wire between us and the classmates opposite us, which causes everyone to ask each other when they go in. This problem is more serious. Fortunately, the teacher scattered these people before everyone shared their criminal experiences.

The only thing that is a little tired is to flatten your face. At first, I felt very discouraged when I saw how depressed I was, but after listening to the lovely teacher et (it looked very similar but nice), it took three years to draw the disciples, and our hearts were more peaceful. I just crossed the line this morning as if nothing had happened. As soon as the afternoon arrived, we were told to look at the lovely iron along the line drawn in the morning! All the women were frightened. After seeing the teacher, we didn't mean to joke, so we had to go back to the big saw and pull it over! At this time, I realized that human potential is infinite: because of me! A weak woman was the first in our class to saw off the iron! Oh, my god When I saw the ninth wonder of the world I created, I really admired myself! But I made a fatal mistake: the machining allowance left is too large!

So I will be depressed for too long. Frustration is a terrible job! I used the remaining 1 day to drop 2 mm steel! Maybe you'll think it's nothing, right Nothing, just frustration! But think about it, a few days ago, I was cutting iron like mud, but I was absent-minded when I watched iron flowers flying around. If I don't cut well, blame the lathe tool. If I cut well, I will praise myself. I didn't know iron was hard. Today, karma came. Let your young heart always remember the fact that iron is hard. Can you stand it? To make matters worse, none of the dead boys around me helped! Don't say it off the court, when it hurts! It's outrageous for a weak woman to do such heavy work! I am depressed! Can't send it! Fortunately, I handed in my work on time when I received it, got the second score in this group, and made a joke (this is another story, not to mention it for the time being). It will be a happy time after the third day.

There are two reasons: 1 We are going to sit and assemble without wasting too much energy. The second is to look at yesterday and yesterday and laugh at the suffering and happiness of our people! ! The morning has passed. Draw a line on the big iron block of 50~70 kg to be processed. Physical and mental exercise. Meet in the afternoon. My happiest time. Because I was not only the first one to finish pretending, but also instructed, no, helped other students. In addition to being happy, I also realized the wisdom of the working class! ! ! On the last day, we punched and assembled the small parts made by the lathe worker before and turned them into real vises. Although only the three of us finished the day's work. But I think the sense of accomplishment belongs only to the three of us. Although I suffered a lot in the locksmith, I really can't bear to leave.

After this locksmith internship, I learned a lot in this field. We have a further understanding of the new term "fitter". A fitter means the operation of cutting metal with a hand-held tool. Before that, I really didn't have a qualitative concept about locksmiths, only knowing what it meant, but I couldn't say clearly. Now I finally understand. More importantly, I not only really understood the meaning of the word "locksmith", but also learned a lot of skills in this field. Suppose the content of this fitter's internship is to make a hexagon nut. I really don't think it looks simple, but when you really do it, you will find it difficult to do it. I was still smiling when I was next to the work materials. Isn't it called sawing a material the size of a small nut? Ah, it's very simple. I wanted to start sawing as soon as I got it, but the teacher stopped me. After listening to the tutor's careful teaching, I realized that this is not a "seesaw", but it should be done according to certain norms. If the size is not selected correctly, a lot of man-hours will be spent. What we want to saw is steel with a diameter of 25mm and a length of 12mm.

I can't say that it took me a lot of man-hours to finalize the specifications of this material, and I am always afraid of making mistakes. What I saw after I decided, I really realized what it means now. "As long as I work hard, iron bars will be ground into rusty needles." I always feel that I have been working hard for it, but I always feel that I can't cut it off. Let's just say, I don't know. It took me a lot of hours to finally saw it off. This time, I saw my hand.

After three weeks of locksmith training, I found my shortcomings in the process of locksmith processing, realized some points that need attention in the process of processing, and learned something that I couldn't learn in textbooks. The necessary knowledge of a locksmith. But also let me deeply understand the great poet-Li Bai's famous saying: as long as the kung fu is deep, the iron pestle is ground into a needle! After several weeks of study, I feel that we have exercised our hands and improved our overall comprehensive quality, which not only makes us deeply understand the significance of locksmith internship, but also improves our practical ability, so that we can better combine theory with practice.

At the beginning of the class, the teacher first explained the basic concept of locksmith to us, and then we just drew some simple sketches with rulers and needles, but because they were drawn on steel plates, we need to pay more attention when drawing.

Then saw and cut. When I first started learning, I was so tired that I was bent over and sweaty. Some red "patterns" appear on my hands from time to time. When I tried to saw the material in a straight line, several saw blades broke and bent a little, which was out of my control. At first, I probably didn't understand the key points and skills of the saw taught by the teacher correctly, so this happened when cutting. But after consulting other students with straight cutting lines, I had to do it when sawing. Later, I noticed these points when I saw them, and the lines I saw were relatively straight, but I was still not familiar with the deep saw, and the saw was still a little off the path of marking.

Locksmiths seem simple, but training is boring. It takes the same foot strength as a horse to keep an action station, check an action, saw or file a day. After a day's work, the backache may not be finished, and it may be scrapped. If there is the possibility of scrapping, we should do it seriously and measure and verify it repeatedly. It is not enough to be careful, but also to work boldly, just like making a workpiece. If you don't leave as little margin as possible when sawing, it will take one or several times of time and energy to process the workpiece when pushing the file. Therefore, as a qualified fitter, we must be "bold but cautious". When filing, it is easy to file a file with uneven ends, often with one side high and one side low, and the size of the other side is small when filing; Finally, the size is good and the surface roughness is not good; Looking back at the fruits of one's labor, I feel that I am out of proportion to my efforts, and I will become more and more irritable. However, the more we do this, the more we can exercise our patience. When filing and planing, you should use horizontal filing method, straight filing method and push filing method. When filing and planing, you should also pay attention to the changes of your filing posture, file holding method and force, so as to file and plane well. Then there is grinding the drill. When grinding, pay attention to the grinding top angle 120, back angle 180, tip 180, and oblique angle of cross blade 60. The most important thing is that the length of the two cutting edges is the same, and the height of the two tips is the same after rotating180. These are all done by the operation of the left hand and the placement angle of the drill bit during grinding. As long as you pay attention to these details when grinding, it is easy to grind the desired bit.

When it comes to locksmiths, many people will find it useless. Who will learn that thing in which era? Dirty and tired, it is better to learn CNC machining center. The locksmith, a seemingly simple type of work, has rich connotations and the saying that "the lathe is great and the locksmith is omnipotent". It is not a simple file grinding, but a basic skill, which can exercise our will. Any small technology is a science, which needs constant study and serious research. It is also necessary to study the seemingly simple bit grinding. To be a good locksmith, you must first have enough patience, secondly have enough physical strength, and finally have a flexible mind. Because locksmith is a type of work with high labor intensity, low production efficiency and high operating skills. The tools he used were simple, varied in processing, flexible and adaptable, and he could accomplish some tasks that could not or were difficult to carry out in processing. In today's era of developed processing industry, although backward, he can't replace Jobs.

In today's scientific development, the competition between enterprises is the competition of talents. Only by constantly cultivating technical talents and improving the technical level of employees can we better meet the development needs of current enterprises. As college students in the new century, only by participating in practice and mastering a skill can we ensure our position in the future social competition. Although the training lasts only three weeks, its significance is far-reaching.

Time flies, and two weeks of locksmith training is over in a blink of an eye. Although I was very tired and bitter during the training, I got a lot of blisters on my hands and put on a lot of band-AIDS, but I felt very fulfilled! Because we have learned the necessary knowledge as fitters and also exercised our hands-on ability. But it also made me more deeply understand the true meaning of grinding the iron pestle into a needle as long as the kung fu is deep!

At the beginning of the first day of training, the teacher told us that the fitter was very bitter and tired, but this was the foundation. Because I once organized a trainee in high school and came into contact with locksmith. I was making a hammer at that time, so the impression of locksmith was quite interesting. But after two weeks of professional training, I know that former students are really superficial. The locksmith seems simple, but it is actually a technical job that tests our patience and perseverance!

At first, the teacher briefly introduced the basic knowledge of locksmith and the tools to be used. Of course, the most important thing is to pay attention to safety. Incorrect operation methods are likely to lead to safety problems. After the teacher introduced us, we went to the field to operate. The first day's task is to draw lines on the plane. The purpose of drawing lines is to clarify the boundaries of processing. For us, drawing lines on the iron plate for the first time encountered many problems. The teacher also knows that it is difficult for us to draw a good floor plan. Before making the plane mark, the teacher told us a lot, and at the same time, the teacher gave us a lot of guidance in the process of making the plane mark. Therefore, under the guidance of the teacher and the mutual help of the students, the students easily completed the first plane marking of the fitter.

The next day's training content is planing and cutting. Before the chisel officially started, the teacher told us the basic knowledge of chisel. The operator's standing position and posture should be convenient for exerting force, with his body center of gravity leaning towards his right leg, slightly leaning forward, his left foot crossing the first half, his knees slightly bent, keeping natural, and his right foot standing straight. The hammer master grasps the hammer handle with five fingers of his right hand, closes his thumb on his forefinger, and points his jaws in the direction of the hammer head. In the process of swinging the hammer, the five fingers are always clenched; Loose grip method, only use thumb and forefinger to hold the hammer handle all the time. The teacher said that at first, because of inexperience, he would knock on his hands. After listening to it, we felt very tired. At first I took a piece of iron and the teacher helped me chisel it. I continued to chisel. I've been chiseling for a long time, less than half, but there are several bubbles in my hand and my finger has been hit several times by a hammer. . . When I couldn't even lift my hands after a day's work, I knew that the locksmith was not as simple as I thought! I decided to work harder!

From grade three to grade five, our training content is filing. This object is still the iron covered with rust yesterday. First saw off one side, and then file the surface flat with a file. Finally, if the line of 0.05 cannot be inserted into four corners, it will be successful. At first, I had no idea about 0.05 silk. Later, the teacher said that our hair is generally 0.08 silk, that is, the diameter is thinner than the hair, and it will not be inserted! In order to achieve this effect, we fell for three days and our hands were blistered. But this is an exercise for us! This is very exercise our will! So I told myself to persist!

After a week of training, I have a basic understanding of locksmiths. Make full preparations for next week!

In the second week of fitter training, first drill holes with different diameters. After drilling, we screw holes and threads. After that, I continued to file. Although I feel bored and tired, it is really not easy to file the final result! Looking at our hands like coal, everyone's face is black, all in order to achieve the final goal-there are less than five lines on both sides, and the angle is vertical! This is the final exam! Although I think it's almost enough, the verticality meets the requirements every time, the parallelism is not enough, or the parallelism meets the requirements. Finally, I can only regret handing in my homework. ...

Although the last assignment was not the best, I learned a lot in this locksmith training, and I learned that things must be done step by step, and I can't rush for success. As long as we have perseverance, we will certainly achieve the best results!

Time passed quickly, and I ended my internship in an instant. This time is really hard, but I have learned a lot. But also let me deeply understand the great poet-Li Bai's famous saying: as long as the kung fu is deep, the iron pestle is ground into a needle! Through the teacher's explanation. I finally understand what a locksmith is. At the same time, I understand why some people say, "Being a fitter is the most tiring!"

Fitter practice is an effective way to cultivate students' practical ability. It is also a compulsory course for our future senior technical workers, especially students who study mechanical assembly and maintenance locksmith. It is very important and meaningful. The fitter's internship is another opportunity for us to actually master knowledge. Without the rigorous environment in the classroom, we will feel the atmosphere in the workshop. At the same time, we feel more about the significance of being a worker, which makes us more aware of our responsibilities.

This is undoubtedly a transition between theory and practice, from safety education, action essentials, the use of tools, to the actual operation of taking files. Some things are to be explored by yourself, and some things are to be discovered from theory and applied to practice. From the beginning of polishing the plane, I understood that it is not that simple to do a good job, and it needs to be proved by practice. What you see is not necessarily true (the plane looks flat, but its shortcomings can be found by measuring light); This reminds me why the school wants us to practice here, because the school wants us to understand the value of learning. Learning needs the same meticulous spirit as polishing an airplane to do its best, and it also makes us realize the importance of hands-on. It's not enough to just study theory. Without practical experience, you can't find your own practical ability, which requires the combination of theory and practice. It needs the cooperation of mind and hands.

From plane grinding to scribing and dot; From shaping to drilling; From reaming to tapping, what I learned at every step was something that others could not take away. From here, I know what a fitter is. The main contents of a fitter are marking, chiseling, filing, grinding, drilling, reaming, reaming, tapping and so on. Understand the structure of the file; Classification, selection, filing posture, filing method and quality inspection.

Fitter practice has trained us and improved our overall comprehensive quality, which not only makes us deeply understand the significance of fitter practice, but also improves our practical ability, so that we can better combine theory with practice. Consolidate what we have learned, and at the same time let us learn the professional quality of teachers. The teacher took pains to find out the mistakes in our homework for us. We also carried forward the spirit of unity and mutual assistance and enhanced the friendship between our classmates.

During the internship, we achieved the fruits of our labor-exquisite nuts. Looking at this exquisite work, it turned out to be polished by myself, and my pride and sense of accomplishment are hard to express in words. I didn't expect that something that was so big at the beginning has now become a beautiful workpiece and has been ground out at once. This is what people say, "As long as you work hard, the pestle can also be ground into a needle"!

The locksmith's internship was short and hard, but what he learned was valuable, which made me realize the hardship and happiness of being a worker and consolidated my knowledge, which left me with good memories.

After such a three-week locksmith internship, what I learned and realized was not available to teachers in class. What is "practice makes true knowledge"? No matter how good your theory is, it will be of no help if your practical ability is poor. I believe that after this locksmith internship, I will lay a solid foundation for the next internship as a lathe worker and welder in a great sense.

In the next semester of the 20__-20__ school year, we conducted a two-week metalworking practice in the training center of the old campus. During this period, I was exposed to the basic operation skills and safety technology courses of fitters and welders. Learn a new technology every week, and you can complete the process from knowing nothing about all kinds of work to making one or two finished products in a few days of internship. With the patient and meticulous teaching of teachers and our active cooperation, we did not have an injury accident, basically met the expected internship requirements and successfully completed the two-week internship.

During the internship, we made our own handicrafts by learning from fitters and welders. The fitter is the hardest and the fitter is the most tiring. The fitter mainly relies on manual operation and uses various tools to complete the processing, assembly and repair of parts. Compared with machining, it has high labor intensity and low production efficiency, but it can complete the work that machining is inconvenient or difficult to complete, and the equipment is simple, so it is still an indispensable and important type of work in mechanical manufacturing and repair. In the fitter's practice, we know that the fitter's main contents are drilling, tapping, sawing and filing, the structure, classification, filing posture, filing method and quality inspection of the file, and the position and important role of the fitter in machine manufacturing and equipment maintenance.

The fitter's factory equipment is relatively simple, because most of them are manual labor. On this day, we will make a 36mm nut in order to familiarize us with the basic work operation of locksmith and exercise our hands-on ability and will. From breaking the iron plate to filing the parallel surface, from punching to screwing, it is not an easy job. Just watching the teacher's demonstration, we were all dumbfounded. Is it possible? Is it necessary to stage a modern version of the iron pestle grinding into a needle?

Because of the time, the teacher didn't say much, but introduced the usage of vice, file and saw. Then let's process a nut with a diameter of 36mm with iron plate, smooth the six surfaces of the nut with a file, drill holes, and finally make six chamfers. After listening, my heart thumped. How long does it take for an iron plate to be processed into nuts? First, clamp the iron plate under a section with a long diameter with a hand saw. According to Ytier, it is not easy. It is necessary to master certain methods. Hold the handle in your right hand and the bow in your left. Thrust and pressure are mainly controlled by the right hand. Pay attention to the pressure on your left hand. The standing posture is that the right front part of the body forms an angle of about 45 degrees with the center line of the vice, the right foot forms an angle of 75 degrees with the center line of the vice, and the left foot forms an angle of 30 degrees with the center line of the vice. Only by using the correct method can we save manpower and improve efficiency. Then draw the size of the nut with a ruler, and finally finalize the nut. After the document is finished, it is followed by six sides. It is not easy to flatten the uneven side. We also need to master the correct methods. The key is to keep the file moving horizontally, which can be achieved by gradually adjusting the pressure of both hands during cutting. In the process of cutting, it is necessary to check whether it is flattened with a square ruler from time to time. After the defeat, I went on to defeat other parties and worked for more than three hours. Finally, six sloppy ones were dealt with. The next step is drilling and tapping, which is not an easy job! Everything should be done carefully according to the steps, and in the end, there are many good things to grind! A few days later, although many students had blisters on their hands and felt sore all over, it was the first time for everyone to see the finished products made in the factory, and they were overjoyed and had a great sense of accomplishment.

Internship experience:

① This internship enables us to cultivate, improve and strengthen our engineering practice ability, innovation consciousness and innovation ability in the process of understanding, being familiar with and mastering certain engineering basic knowledge and operation skills.

② We have cultivated and exercised our views on labor, quality and economy, enhanced our awareness of observing labor discipline, safety technical regulations and caring for state property, and improved our overall comprehensive quality. Metalworking practice plays a comprehensive training role in cultivating our engineering quality and ability, which requires us not only to learn the basic process knowledge of each type of work, understand the equipment principle and working process, but also to strengthen the training of practical ability and have the ability to analyze and solve simple process problems by using the learned process knowledge.

(3) In the whole practice process, we have strict discipline requirements, formulated the rules for students' practice, and strengthened the requirements of filling in the practice report, cleaning the work site, and observing the safety operation rules of work types, which has played a good role in promoting the cultivation of students' comprehensive engineering quality.

(4) The teacher of the training center announced the grading standards of our processed products to us, which made us have a clear understanding of our own product grading and played a certain role in improving our quality awareness. For our metalworking practice results, a comprehensive evaluation system is implemented, and the usual results+product quality results+comprehensive assessment results = total results. Let us take every job and every practice link seriously.

During my internship, I was deeply touched. Thank you very much for providing us with this internship opportunity, so that we can experience the difficulty of studying engineering in advance and gain knowledge that we can't get in class and can't expect. Maybe we won't take this post in the future, but the knowledge and feelings we have learned now are unforgettable. It's dirty and tired, but it doesn't matter. The important thing is that we have achieved and achieved results. The two-week metalworking practice brings us not only the operational skills we are exposed to, but also the ability we need to exercise through several types of work. More importantly, we need each of us to feel, reflect, work hard, encourage ourselves and gain something after practice, so that this practice can achieve the real goal.
