[0003] For example, the authorization announcement number "CN220881947U" is a positioning component for processing a lifting base plate. The lifting base plate can be pressed and fixed by a pressing mechanism and a square tube, and can be raised and lowered by adjusting the lifting screw through a screw. At the same time, the lifting base plate can be flipped through an angle adjustment mechanism to process different surfaces. However, when the device presses and fixes the lifting base plate through a pressing mechanism and a square tube, it cannot ensure that the lifting base plate is in the center position for processing, which can easily lead to processing failure and reduce the working quality of the device. When processing the lifting base plate, the device will cause waste chips to splash, and the splashing waste chips can easily cause damage to the operator, reducing the safety of the device.

[0026] Working principle:

[0027] Auxiliary positioning and clamping process of the lifting base plate:

[0028] The operator places the lifting base plate on the surface of the load-bearing platform 4, connects the external power supply of the second motor 201, starts the output shaft of the second motor 201 to rotate and drive the first threaded rod 202 to rotate. The rotation of the first threaded rod 202 drives the first threaded block 203 to move upward. While the first threaded block 203 moves upward, it drives the protrusion 204 to move inward. The protrusion 204 drives the sliding rod 205 to move synchronously. While the sliding rod 205 moves, it drives the splint 206 to move synchronously. The splints 206 on both sides move at the same time, contact and tighten and fix the lifting base plate, completing the auxiliary positioning and clamping of the lifting base plate. The synchronous movement of the splints 206 on both sides realizes the center positioning and clamping of the lifting base plate, which is convenient for the subsequent grinding of the lifting base plate. When the grinding is completed, the above process is controlled and the reverse operation can no longer position and clamp the lifting base plate, and the operator can take it out.

[0029] Auxiliary protection process for grinding the lifting base plate:

[0030] Since waste chips will fly when the lifting base plate is polished, the external power supply of the first motor 301 is connected, and the output shaft of the first motor 301 is started to rotate, driving the gear 303 to rotate. The rotation of the gear 303 drives the rack 304 to move upward, and the upward movement of the rack 304 drives the baffle 306 to move synchronously. When the baffle 306 moves to the extreme position, the operator screws the bolt 307 into the first shell 302. When the end of the bolt 307 is tightly against the baffle 306, the position of the baffle 306 is fixed, completing the auxiliary protection process for the polishing of the lifting base plate, avoiding waste chips from splashing onto the operator's body surface during the subsequent polishing process. When the polishing is completed, the above process is controlled, and the reverse operation can drive the baffle 306 to return to its original position, making it convenient for the operator to observe or remove the lifting base plate.

[0031] The grinding process of the lifting base plate:

[0032] Connect the external power supply of the grinder 12, start the grinder 12, control the extension of the output end of the hydraulic cylinder 7 to drive the grinder 12 to move downward, and when the grinding roller of the grinder 12 contacts the surface of the lifting base plate, it grinds it. When it is necessary to adjust the grinding position, connect the external power supply of the third motor 9, start the output shaft of the motor 9 to rotate and drive the second threaded rod 10 to rotate. The rotation of the second threaded rod 10 drives the second threaded block 11 and the grinder 12 to move and adjust the horizontal grinding position. When it is necessary to adjust the longitudinal grinding position, the auxiliary positioning clamping device can be used to adjust the longitudinal grinding position of the lifting base plate to complete the grinding process of the lifting base plate. The working principle of the grinder 12 is consistent with that in the authorization announcement number "CN220881947U".
