internship summary

In the practice of locksmith, we know that the main data of locksmith are scraping, drilling, tapping, sawing, filing, assembling and scratching; Understand the structure, classification, selection, filing posture, filing method and quality inspection of archives. First of all, we must get the right gear. Sticking to the linear motion of the file when filing the plane is the key to filing. 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. When the file returns, no pressure is applied. This will make it easier for us to file.

Then there are scraping, grinding, drilling, reaming, tapping 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 the results of self-treatment, what we want to say most is to thank the teachers who guided us. Turning is not done by numerical control, which requires high manual operation skills.

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. But with my encouragement, the boys in the same group saw the iron without being the last one. It's good. Followed by scribing and drilling. It's nothing.

Because teachers and machines do more. There is nothing unusual in 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 noon arrived, we were told to look at the lovely iron along the line drawn in the morning! All the women were frightened. No kidding, after reading the teacher, we have to resign and go back to the big saw ourselves! 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 I really fell in love with myself when I saw the ninth wonder of the world I created!

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 don't understand that iron is 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! But fortunately, when I received the work, I handed it in on time, got the second score in this group, and made a joke (this is another story, let alone 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 at noon. 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! Finally, one day, we punched and assembled the small parts made by the lathe operator before and turned them into a real vise. 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.

Locksmith experience:

After this locksmith internship, I learned a lot in this field. Right? Fitter? This new term has been further understood, the meaning of fitter: the operation of cutting metal with hand-held tools. Before that, I really didn't have a qualitative concept about locksmiths, only knowing what it meant. I couldn't say clearly, but I finally understood it at this moment. What's more, don't I really put this? Fitter? Besides understanding the meaning of the word "hexagon nut", I also learned a lot of skills in this field. Suppose the information of this fitter's internship is to make a hexagon nut. 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 want to start sawing as soon as I get it. At this moment, I was stopped by the teacher. After listening to the tutor's serious lecture, I realized that it was different? Saw? It must be manufactured according to the necessary specifications. 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. I started sawing when I was sure, and I didn't really realize it until now. What is this? As long as the kung fu is deep, the iron bar is ground into a rusty needle? The truth, I always feel like I'm still doing it? Work hard? Saw, but I always feel that I can't cut it off. Let's just say, I don't know how many hours it took, okay.

It is not easy to saw it off. This time, I saw a big blister on my hand. At that time, I didn't feel pain. I didn't find it really painful until I finished my work.

Summary of skilled workers' work II Starting from fitter training, I found my own shortcomings in fitter technology, recognized some points that need attention in the processing process, and learned something that I can't learn in textbooks. The necessary knowledge of a locksmith. This also made me realize this great poet more deeply? Li Bai's famous saying: As long as the kung fu is deep, the iron pestle is ground into a needle. After several weeks' study, I feel that we have exercised our hand and improved my overall comprehensive quality, which not only gives us a deep understanding of the significance of locksmith internship, but also improves our practical skills, 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.

After that, I sawed off the material. When I first started learning, I was hunched over and sweaty. Some red ones appear on your hands from time to time? Pattern? When cutting, I saw the material as straight as possible, and even broke several saw blades, which were a little crooked and 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 scene will appear when cutting. But after consulting other students with straight cutting lines, I should pay attention to whether the saw blade is straight before and after sawing. I noticed these points when I saw them later, and the lines I saw were relatively straight, but I was still unfamiliar with them when I saw them deeply, and I still deviated from the path of marking.

Locksmiths seem simple, but training is boring. Stick to an action for a day, check, saw or file an action. This requires the same foot strength as a horse. After a day's work, the backache may not be finished, and it may be scrapped. If there is no possibility of scrapping, we must do it seriously and measure and verify it repeatedly.

It is not enough to be cautious, but also to work boldly, just like doing 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. So, as a qualified fitter, you must have? Bold and cautious? . When filing, it is easy to file a file with uneven ends, often with one side high and one side low and the other side small in size; The size is difficult to get right and the surface roughness is no longer good. Looking back on my own labor achievements, I feel that I am out of proportion to my own efforts, and I will feel 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 a good plane. Then grinding the drill bit. It should be noted that the grinding vertex angle should be 120? The back angle should be high at the front and low at the back, the tip should be high at the left and low at the right, and the oblique angle of the cross blade should be 60? Left and right, the most important thing is that the two cutting edges are equal in length, rotating 180? The last two tips are equal in height.

These are all done by left-handed operation 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.

Fitter, a seemingly simple job, has rich connotations. The lathe worker is great, and the fitter can do anything? Statement. 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 is only a few weeks, its significance is far-reaching.

The summary of skilled workers' work flies in three hours. In a blink of an eye, I have been an intern locksmith in xx Company for two months. Although I was very tired during the internship, I was very happy, because we learned a lot of practical things during the internship and also exercised our practical ability. In addition, I have gained a lot from my mentality and work skills.

To carry out locksmith practice, the safety problem must be put in the first place. On the first day we arrived at the company, the company organized the manager of the security department to explain the safety production regulations to us, and then passed the safety knowledge examination and officially took up the post. After the manager's explanation, we learned about the dangerous operation actions that are easy to make in the internship. For example, fighting in the workshop, operating the machine tool without the permission of the master, incorrect method and posture during operation, and so on. An unintentional action or a small negligence may lead to mechanical accidents or even personal safety accidents. The case in explanation has sounded the alarm for our future practice.

When I was at school, I heard the teacher say: fitters are the most tired. After more than two months of internship, I finally believe this sentence and understand what a locksmith is. The fitter mainly relies on manual operation and uses various tools to complete the processing, assembly and repair of parts. Compared with mechanical processing, it has high labor intensity and low production efficiency, but it can complete tasks that are inconvenient or difficult to complete in mechanical processing, and the equipment is simple, so locksmith is still an indispensable and important type of work in mechanical manufacturing and repair.

On my first day in the workshop, the first part the master asked me to make was a nut. After listening to the master's request and looking at the seemingly simple patterns on the blackboard, I started my first task. First, measure and draw a line on the iron block. Draw lines, this work can't be sloppy. If something goes wrong, it will make my parts out of size. Fortunately, after listening to what the master said, I drew the size a little bigger according to what the master said. After that, I will never forget the seesaw. I thought sawing saw meant dragging it back and forth. No big deal. This is a piece of cake. But the truth is, sawing also requires skill. If you just drag it back and forth, no matter how strong you are, your hands will be numb and your eyes will panic.

First, we should adjust the direction of the incision. According to the kerf direction, the thumb of the left hand leans against the saw blade to prevent the saw blade from sliding sideways, and the right hand pushes the handle steadily. The saw blade should be inclined to the workpiece by a saw angle of about 10 ~ 15. If the saw is too big, the saw blade is easy to break; if the saw angle is too small, the saw blade is not easy to cut in, and it may slip and damage the surface of the workpiece.

At the same time, when sawing, the right hand holds the saw handle and the left hand gently holds the front end of the bow. The saw bow should reciprocate in a straight line and cannot swing. The pressure is even when moving forward, and the saw blade gently slides over the workpiece when moving backward. The reciprocating speed should not be too fast. Before and after sawing, the pressure and speed should be reduced to avoid hurting the arm and breaking the saw blade. A small amount of engine oil can be added.

When I started sawing, I really suffered a big loss, because I always pulled and pushed hard, and I saw hard. As a result, I broke a saw blade and had problems eating the next day. My right hand is like a crack. After the teacher explained, I finally learned how to saw things. After sawing, you need to file it. Filing is also a tiring and bitter thing, but it is not difficult as long as you master the method.

First of all, holding the file correctly is the key, and the linear motion of the file is the key. There are two kinds of filing force: horizontal thrust and vertical pressure. When pushing the file forward, the front hand pressure gradually decreases, and the back hand pressure first increases and then decreases. When the file is pushed to the middle position, the pressure on both hands is the same. When pushing the file forward, the pressure of the front hand gradually decreases and then increases. When the file returns, no pressure is applied. This will make it easier for us to file.

Then there are scraping, grinding, drilling, reaming, tapping and so on. With our efforts, a black iron block turned into a smooth and lovely nut? Although it is not very standard, it is the crystallization of our sweat and the result of our three-day struggle. It's as simple as finishing the parts one by one. In fact, only by doing this can we truly appreciate the hardships and tiredness of being a fitter. Why are some people called fitters? The fitter is hell, but we will also experience the happiness and joy of being a fitter.

After more than two months of practice, I have a further understanding of the processing technology such as marking, chiseling, sawing, filing, drilling, reaming, tapping, hooking, scraping and grinding. At the same time, I also found that

My own shortcomings in locksmith's work, I realized some points that need to be paid attention to in the process of processing, learned things that I can't learn in textbooks, and accumulated some work experience for my future work. At the same time, in this stage of practice, I also summed up some experiences:

In order to process accurate workpieces, the required dimensions must be drawn accurately first. Before scribing, clean the surface of the workpiece to remove burrs and scale. Then evenly brush on the surface of the damaged workpiece to make the mark clearer. Scribing must be careful, if not careful, it will bring errors to subsequent processing. The convex-concave edge of the convex-concave matching workpiece and the dovetail edge of the dovetail matching should be symmetrical and accurate, so as to adhere to the positive and negative matching of the matching parts.

According to the remaining width of the required workpiece, decide whether to file first or chisel first, or file after sawing. If the remaining amount is small, you can file it directly with a file. Choose a file with medium teeth, with the center of the right hand facing the end of the file handle, the thumb on the top of the file handle, and the other four fingers on the bottom, and hold the file handle with the thumb. The left palm is pressed against the other end of the file, and the thumb is naturally straightened, and the other four fingers are bent to buckle the file tip. Hammer in left hand, chisel in hand, chisel back 5? ~8? Start with a slightly larger back angle. When chiseling, the thickness of chiseling is about 0.5 ~ 2 mm at a time. When chiseling a large plane, slot with a narrow chisel first, and then level with a flat chisel.

If the remaining width of the required workpiece is large, it should be sawed first. When installing, the sawtooth tip is forward, and the saw blade should not be too tight or too loose when installed on the saw bow. When sawing, the saw blade should be perpendicular to the working surface, and hold it firmly with the thumb of the left hand, so that the saw blade can be sawed to the required position correctly. The sawing angle is about 10? About. When the saw blade is pushed forward, appropriate pressure should be given to play a cutting role. When it is returned, it should not be cut. The saw should be lifted slightly, or the saw blade should be scraped off the workpiece slightly to reduce wear. When sawing, you should use light force to avoid hurting your arm. The sawing speed depends on the material and hardness of the workpiece. When sawing hard materials, it should be lower, and when sawing soft materials, it can be higher, generally reciprocating 40 ~ 60 times per minute.

Before drilling, the workpiece should be crossed and centered. Draw an aperture circle and a calibration circle at the position of the workpiece hole, and make a small pit on the aperture circle and the center. When drilling, first try to drill a shallow hole on the sample punch. If there is any deviation, you can punch it again with the sample and correct it with the chisel. When drilling, the feed speed should be uniform. When drilling, the feed rate should be reduced and cutting fluid should be added to drill tough materials. When drilling deep holes, the drill bit should be pulled out frequently to facilitate chip removal and cooling.

Do 60? Dovetail angle should be measured by universal angle ruler, and the marking should be accurate to ensure the correct angle, and attention should be paid to the symmetry of both sides. Use compasses when making fillets, and use a file to correct them after drawing clear lines.

Finally, the matching part should be corrected when matching, and be careful not to wear it out, leaving a little at a time to prevent the adjacent edges from being worn out when correcting them.

Fitter internship is boring. He may have been repeating an action all morning, but he still needs strength and accuracy, that is, holding a file back and forth on the workpiece. By noon, the whole person's hands were sore and his legs were stiff. However, when he is tired, he can see the master personally guiding and demonstrating. He is also sweating and panting. Looking at my own processing results, I want to say thank you to my master who has always supported and encouraged me.

More than two months of locksmith internship, I think it is very meaningful. Although it was very hard and tiring, we did learn a lot of locksmith knowledge, and we also learned a lot of work experience while chatting with the locksmith master. When we young people first join the work, no matter how difficult it is, we should be patient and just hold our horses. Don't quit your job as soon as you see that it is a little tired and difficult, and jump ship at once. It is unwise and incorrect to do so. Young people must first learn to master work experience and learn real technical knowledge, which is the most important thing. So I am very grateful to the school and the master for giving me such a rare internship opportunity to exercise my will and cultivate my skills. Next year, I will leave school and formally enter the society. After this internship, I have understood and figured it out. No matter where I work, no matter whether my work is good or not, I will stick to it and do my best.
