[0002] A locking nut is a nut widely used in machinery and other industries. Its working principle is to use the friction between the nut and the bolt for self-locking. When producing locking nuts, its surface needs to be polished. The Chinese utility model patent, authorization announcement number "CN220718737U", discloses a polishing device for nut processing, specifically relating to the field of nut processing equipment, including a base, support frames are arranged on both sides of the base surface, a material guide assembly is arranged at the center position of the support frame surface, a cross bar is arranged on the top of the material guide assembly, a nut is arranged on the movable sleeve outside the cross bar, clamping blocks are arranged on both sides of the nut, a cylinder is arranged on one side of the clamping block, a first hydraulic cylinder is fixedly arranged at the bottom of one end of the cylinder, and a polishing roller is arranged on the top of the nut.

[0003] The above technical scheme can set a cross bar by setting a cross bar, so that multiple nuts can be sleeved on the outside of the cross bar, so that the two clamping blocks can first shape the nuts and then clamp them through the cylinders set on the outside, and then control the first hydraulic cylinder and the second hydraulic cylinder to rise, so that the cross bar drives the nuts to rise and contact the surface of the grinding roller. At the same time, the clamping blocks can keep the nuts fixed and clamped, so that multiple nuts can be polished at the same time and work efficiency can be effectively improved. However, the above scheme not only needs to put the nuts on the cross bar one by one, but also when processing nuts with different inner diameters, it is necessary to replace the cross beam before continuing with the subsequent grinding process. The whole process is rather cumbersome. Utility Model Content

The bracket 4 is provided with a sliding groove, the bracket 4 is welded on the locking nut grinding workbench 1, the motor 1 6 is mounted on the bracket 4 by screws, the electric telescopic rod 2 5 is mounted on the output shaft of the motor 1 6, the two support members 12 are respectively mounted on the corresponding electric telescopic rod 3 11 by screws, the two sponge pads 13 are respectively adhered to the corresponding support members 12, the two electric telescopic rods 1 3 are respectively mounted on both sides of the bracket 4 by screws, and the two clamping plates 2 are respectively mounted on the corresponding electric telescopic rod 1 3 by screws;

[0025] The grinding assembly is arranged on the bracket 4, and the grinding assembly includes a connecting piece 7, a second motor 8, a grinding roller 9, a threaded rod 14, a gear 15, a second gear 16 and a motor 3 17. The threaded rod 14 rotates and passes through the bracket 4, and the connecting piece 7 slides along the sliding groove provided in the bracket 4. The surface of the threaded rod 14 is threadedly connected with the surface of the connecting piece 7. The second motor 8 is installed on the lower side of the connecting piece 7 by screws, and the grinding roller 9 is installed on the output shaft of the second motor 8.

[0026] The connecting frame 10 is mounted on the electric telescopic rod 2 5 , and the two electric telescopic rods 3 11 are respectively mounted on both sides of the connecting frame 10 by screws.

[0027] The motor three 17 is mounted on the bracket 4 by screws, and the gear two 16 is mounted on the motor three 17 by key pins.

[0028] Gear 1 15 is sleeved on the threaded rod 14 , and the surface of gear 2 16 is meshed with the surface of gear 1 15 .

[0029] When the locking nuts need to be polished in batches, first, the locking nuts are stacked and arranged with the threaded holes facing upward and placed at a suitable position on the locking nut polishing workbench 1.

[0030] It should be noted that it is only necessary to ensure that the locking nuts are stacked and the axes of the nut threaded holes are roughly consistent, and there is no need to ensure that all the axes of the threaded holes are in one line.

[0031] Secondly, start the two electric telescopic rods 1 3 to drive the corresponding clamping plates 2 to move relative to each other, and drive the central axis of the threaded hole of the locking nut to be on the same horizontal plane.

[0032] Next, the motor 1 6 is started to drive the two sponge pads 13 to rotate 90°, and then the electric telescopic rod 2 5 is started to drive the connecting frame 10 to move downward, the downward movement of the connecting frame 10 drives the two electric telescopic rods 3 11 to move downward, the downward movement of the two electric telescopic rods 3 11 drives the corresponding supporting members 12 to move downward, and the downward movement of the two supporting members 12 drives the corresponding sponge pads 13 to move downward into the threaded holes of the nut.

[0033] Then, the two electric telescopic rods 11 are started to move away from each other by the same distance so that their locking nuts can be positioned.

At the same time, the support component can be used to put batches of nuts on the two sponge pads 13, so that the positioning nuts before grinding can be completed more quickly, thereby improving the efficiency of batch grinding of nuts.

[0036] By setting up the motor three 17 of the grinding assembly, the motor three 17 moves to drive the grinding roller 9 to move and grind the nuts clamped on the two sponge pads 13, so that the grinding device can grind nuts of different sizes according to needs. At the same time, two sponge pads 13 are used, and the two sponge pads 13 can better fit the threaded holes of the nuts, thereby increasing the clamping area, making the clamping more stable, facilitating subsequent grinding work, and improving the stability of the grinding work.

[0037] Working principle:

[0038] When the locking nuts need to be polished in batches, first, the locking nuts are stacked and arranged with the threaded holes facing upward and placed at a suitable position on the locking nut polishing workbench 1.

[0039] Secondly, start the two electric telescopic rods 1 3 to drive the corresponding clamping plates 2 to move relative to each other, and drive the central axis of the threaded hole of the locking nut to be on the same horizontal plane.

[0040] Next, the motor 1 6 is started to drive the two sponge pads 13 to rotate 180°, and then the electric telescopic rod 2 5 is started to drive the connecting frame 10 to move downward, the downward movement of the connecting frame 10 drives the two electric telescopic rods 3 11 to move downward, the downward movement of the two electric telescopic rods 3 11 drives the corresponding supporting members 12 to move downward, and the downward movement of the two supporting members 12 drives the corresponding sponge pads 13 to move downward into the threaded holes of the nut.

[0041] Then, the two electric telescopic rods 11 are started to move away from each other by the same distance.

[0042] Finally, start motor three 17. The start of motor three 17 drives gear two 16 to rotate. The rotation of gear two 16 drives gear one 15 to rotate. The rotation of gear one 15 drives the threaded rod 14 to rotate. The rotation of the threaded rod 14 drives motor two 8 to move close to the locking nut. At the same time, start motor two 8 to drive the grinding roller 9 to rotate.
