Working principle of drilling machine

Usually, the rotary motion of the drill bit is the main motion, and the axial motion of the drill bit is the feed motion. In the process of machining, the workpiece does not move, so the tool moves, the center of the tool is aligned with the center of the hole, and the tool rotates. The characteristics of drilling machine are that the workpiece is fixed and the cutter rotates. There are two main working modes of drilling machine:

1. Accurately locate the place where the workpiece needs to be drilled. There are two positioning methods: one is tool positioning, and the other is special tool positioning.

Tool positioning: Tool positioning is based on the rotation center of props and machine tools, and the tool and machine tools are positioned through a rotation center during rotation.

Special tool positioning: Special tools use positioning special tools such as tips for positioning.

2. Drill holes for anchor points, and drill holes for points that have been accurately positioned.

Be sure to check thoroughly before use, and then use it if everything is normal. 3. The maximum aperture shall not exceed 12mm, and the hand must be clenched when adjusting the height. 4. When in use, the workpiece should be fastened on the flat-nose pliers, the drill should be clamped and the fixing parts should be tightened. 5. When drilling holes in steel parts, coolant must be used. When drilling, the pressure should be light. Don't touch or blow the iron filings in your mouth. 6. When drilling, the cuffs and hair should be tied tightly. Do not wear gloves. 7, concentrate when drilling, it is forbidden to laugh, must clean up the scene after use. 8, when drilling accident, should immediately stop. If there is an accident, report it immediately. 1. Safety protection preparation before work. Add grease as needed. Check the handle position of protection operation. 2.

Female students and male students with long hair must wear work hats. 3, it is forbidden to wear gloves, so as not to be stuck by the rotating part of the drilling rig, causing an accident. 2. Before installing the drill bit, carefully check the drill sleeve. The standardized cone of drill sleeve should not collide. If so, it can only be used after being repaired and wiped with an oilstone. Standard pheasant iron must be used for disassembly. 3. When drilling thin plate parts, small workpieces, reaming holes or drilling large holes, it is forbidden to hold them by hand for processing. Four, without the permission of the instructor, shall not start the rig. When the machine tool is not stopped, it is forbidden to rotate the speed-changing disc to change speed, and it is forbidden to hold the drill bit or drill chuck that is not stopped by hand. Only one person is allowed to operate. Five, iron filings should be removed with tools such as brushes, not directly cleaned by hand or blown by mouth. Six, after the work, to clean up the machine tool, refueling maintenance, cut off power supply, do a good job in the field health. .

What kinds of drilling machines are there?

Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in workpieces. According to the purpose and structure, it is mainly divided into the following categories: 1. Vertical drilling machine Second, the table drilling machine. Third, the radial drilling machine. Four, deep hole drilling machine. Five, vertical drilling machine. Six, the center hole drilling machine. Seven, milling machine and drilling machine. Eight, horizontal drilling machine.

Commonly used horizontal drilling machine models

Drilling machine is a kind of hole processing machine. It is mainly used for machining holes on workpieces with complex shapes and no rotational symmetry axis, such as single holes or hole systems on boxes, supports and other parts. A drilling machine is a machine tool that uses a drill bit to process holes in a workpiece. Usually used for machining holes with small size and low precision requirements. When machining on a drilling machine, the workpiece is generally fixed, and the cutter mainly rotates and feeds along the axial direction. Drilling machine can complete drilling, reaming, reaming and tapping. The main parameter of drilling rig is the maximum drilling diameter.

What kinds of drilling machines are there?

Bench drill, vertical drilling machine, horizontal drilling machine, radial drilling machine, single-axis drilling machine, multi-axis drilling machine, fixed drilling machine, mobile drilling machine, magnetic drilling machine, sliding drilling machine, semi-automatic drilling machine, numerical control drilling machine, deep hole drilling machine, gantry numerical control drilling machine, combined drilling machine, drilling and milling machine,

6. Milling and drilling machine

The workbench can move vertically and horizontally, and the drill shaft is arranged vertically, which can be used for milling.

7. Horizontal drilling machine

Horizontal spindle and vertical spindle box drilling machines. Generally, it is more efficient than vertical drilling machine, and can process multiple faces at the same time.

The difference between horizontal drilling and milling machine and vertical drilling and milling machine and their processing characteristics.

Difference:

1: The quality of the horizontal milling machine is stable. Horizontal milling machine can process various planes, inclined planes and grooves with various cylindrical milling cutters, circular milling cutters, angle milling cutters, forming milling cutters and end milling cutters. If appropriate milling machine accessories are used, parts with special shapes such as gears, cams, circular grooves and helicoids can be processed, and milling machine accessories such as universal milling head, frustum and indexer are provided. After using the boring tool bar, you can also process the holes of small and medium parts. The vertical milling head is added, and the vertical milling cutter can be used for cutting, which can further expand the application range of the machine tool.

2. The vertical drilling machine can feed automatically, and its power and mechanical strength allow higher cutting capacity, so it can obtain higher labor productivity and higher machining accuracy. The spindle speed and feed speed of vertical drilling machine vary widely, which can adapt to the machining of different material tools on different material workpieces. It can also meet the needs of different processes such as drilling, reaming, reaming and tapping. The vertical drilling machine is equipped with a set of multi-spindle transmission heads, which can drill dozens of holes at the same time and can be used as a special machine tool for mass production.

Features of horizontal milling machine:

1. The spindle sleeve can be manually micro-fed, and equipped with a limiting device, and the milling head can rotate 45 clockwise and counterclockwise;

2. The workbench can be manually fed and lifted vertically in the longitudinal and transverse directions, and at the same time, it can realize longitudinal and transverse fast feed, motor feed and vertical motor lifting;

3. Using 1200mm telescopic slider and 1500mm telescopic workbench, the longitudinal stroke of the workbench can reach 1000mm, with long stroke and stronger stability;

4. The main drive and feed adopt gear speed change mechanism with wide speed range;

5. Tapered roller bearing is adopted for the spindle bearing, which has strong bearing capacity, energy consumption braking, large braking torque, emergency stop and reliable braking;

6. The rectangular guide rail has good stability;

7. The workbench and guide rail adopt ultrasonic frequency quenching, which has greater strength.

Characteristics of vertical drilling and milling machine

1, which can realize vertical and horizontal milling functions.

2. There are two feed modes for vertical shaft sleeve: manual feed and micro feed.

3. Grinding the guide rail pair of the workbench after ultrasonic quenching.

4. The workbench can be divided into three kinds of motorized feeding modes: Type A is three-way; Type c is unidirectional; Type d is two-way.
