Description

Technical Field

[0001] The utility model relates to the technical field of metal lock processing, in particular to a grinding device for metal lock processing. Background Technique

[0002] The lock body is one of the components of a lock. There are many types of lock bodies, such as single-sided lock bodies, three-sided lock bodies, four-sided lock bodies, etc. They are generally used on anti-theft doors and are responsible for the basic anti-theft work of anti-theft doors. The grinding of the lock body is to grind the two end faces of the lock body. By grinding the two end faces of the lock body, the size of the lock body reaches the standard, and the end faces are smooth.

[0003] For example, a grinding device for metal lock processing with the authorization announcement number of "CN220881765U" clamps and fixes the lock by placing it at the clamping component on one side of the circular plate. By enabling the lifting component to drive the motor frame to lift, its height can be adjusted, and then the clamping component and the grinding equipment can be driven to adjust the height. When grinding the lock with this device, the lock needs to be placed at the clamping component on one side of the circular plate for clamping and fixing, and then the electric push rod is started to drive the grinding motor and the grinding wheel to move down for lock grinding. This process requires the operator to manually clamp and fix the lock, which will cause the operator to be too close to the device and easily lead to safety accidents. At the same time, when grinding the lock with the above device, the position of the electric push rod needs to be moved left and right to drive the grinding wheel to move and grind other positions of the lock. This process also needs to be manually completed by the operator, which will reduce the work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of easy occurrence of safety accidents and low work efficiency of this device, and to propose a grinding device for metal lock processing.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a grinding device for metal lock processing, including support legs and a processing table.

The other end of the second threaded rod penetrates through the processing table and is threadedly connected to the second threaded block.

[0010] Preferably, the auxiliary grinding device includes a strip-shaped box and grinding discs. The back of the strip-shaped box is fixedly connected to the first threaded block. The inner wall of the strip-shaped box is fixedly connected to a strip-shaped plate. A rack plate is fixedly connected to the lower end of the strip-shaped plate. The lower end of the strip-shaped plate is fixedly connected to a fixed block. The surface of the fixed block is movably connected to a first straight plate through a pin shaft. The first straight plate is movably connected to a second straight plate through a pin shaft. The second straight plate is movably connected to a fixing plate through a pin shaft. Both ends of the fixing plate are movably connected to two side gears through pin shafts. The surfaces of both sides of the gears are engaged with teeth opened on the surface of a square plate.

The output shaft of the fifth motor penetrates through the fixed block and is fixedly connected to the first straight plate. The lower end of the strip-shaped box is fixedly connected to two bent plates.

[0012] For a grinding device for metal lock processing proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the clamping device and the processing table, when the lock is placed on the surface of the placement table, the output shaft of the second motor drives the second threaded rod to rotate. The second threaded rod drives the square block to move upward through the second threaded block, so that the two clamping plates clamp the lock, avoiding the problem of safety accidents caused by the operator manually clamping the lock and being too close to the device.

[0013] Through the cooperation of the auxiliary grinding device and the grinding disc, when the strip-shaped box moves to an appropriate distance, the output shaft of the fifth motor drives the first straight plate to rotate. The first straight plate drives the two side gears to rotate through the second straight plate and the fixing plate, so that the gears drive the grinding disc on the square plate to grind the lock, eliminating the need for manual grinding by the operator and improving work efficiency.

[0034] Auxiliary grinding process:

[0035] Connect the external power supply of the first motor 11. The output shaft of the first motor 11 drives the first threaded rod 9 to rotate. The first threaded rod 9 drives the first threaded block 5 to move downward. The first threaded block 5 drives the strip-shaped box 801 to move downward. When it moves to a suitable position, connect the external power supply of the fifth motor 805. The output shaft of the fifth motor 805 drives the first straight plate 806 to rotate clockwise (as Figure 6 ), the first straight plate 806 drives the second straight plate 807 to move, and the second straight plate 807 drives the fixing plate 808 to move leftward, so that the fixing plate 808 drives the square plate 811 to move leftward through the gears 813 at both ends.

The output shafts of the third motor 813 and the fourth motor 814 drive the grinding discs 812 on both sides to rotate clockwise (as Figure 6 ), to grind the left end of the metal lock. According to the above operations, when the first straight plate 806 rotates to a certain angle, it drives the square plate 811 to move rightward to grind the right end of the metal lock. When it is necessary to grind other surfaces of the metal lock, loosen the clamping plates 702 on both sides to turn over the metal lock, and then operate according to the above clamping process to grind other surfaces of the metal lock.
