The second gear ring 301 meshing with the second gear 302 is installed on the inner wall of the base 101.

[0047] The connecting rod 304 rotates to drive the rotating platform 104 and the rotating shaft 303 to rotate. The rotating shaft 303 drives the second gear 302 to rotate on the second gear ring 301 to achieve self-rotation. The rotation of the second gear 302 can drive the receiving rod 401 to rotate.

One end of the receiving rod 401 is connected to the rotating shaft 303, and the other end of the receiving rod 401 is slidably sleeved with the sleeve 403. The two ends of the first return spring 404 are respectively connected to the inner wall of the sleeve 403 and the top wall of the receiving rod 401. The sleeve 403 is provided with a workbench 402 at one end away from the receiving rod 401. The workbench 402 is installed with a clamping frame 405, and the inner wall of the clamping frame 405 is symmetrically slidably provided with a clamping plate 406. The two ends of the second return spring 407 are respectively connected to the side wall of the clamping plate 406 and the inner wall of the clamping frame 405. A rubber pad is provided on the opposite side of the clamping plate 406. The workbench 402 is symmetrically provided with an unlocking mechanism 500 that cooperates with the clamping plate 406 in pulling.

[0049] The rotation of the receiving rod 401 can drive the first return spring 404 and the sleeve 403 to rotate, and the sleeve 403 drives the workbench 402 and the clamping frame 405 to rotate. The brake pad body 115 is clamped and fixed on the clamping frame 405, so that the brake pad body 115 can rotate.

[0050] Reference Figure 6-Figure 7 : The unlocking mechanism 500 includes an unlocking rope 501, a limiting ring 502, a ball 503 and a slide rail 504.

[0051] When the workbench 402 rotates to above the slide rail 504, the sleeve 403, the workbench 402 and the clamping frame 405 rise through the cooperation of the ball 503 and the slide rail 504. At this time, the unlocking rope 501 pulls the clamping plate 406 back to unlock the brake pad body 115. In this way, the unlocked brake pad body 115 can be removed by the mechanical claw and a new brake pad body 115 that needs to be polished can be placed.

[0052] Reference Figure 2-Figure 3: The cleaning mechanism 600 includes a rotating rod 601, a synchronous belt 602, a support frame 603, a mounting block 604, a fixed block 605 and a cleaning brush 606. There are three mounting frames 105 arranged on the side wall of the support stand 102, and the supporting frames 603 are all installed on the symmetrically arranged mounting frames 105. One end of the rotating rod 601 is rotatably matched with the top wall of the supporting frame 603, and the other end of the rotating rod 601 passes through the side wall of the mounting frame 105 to connect the mounting block 604.

When the brake pad body 115 passes under the fixed block 605, since the fixed block 605 is made of elastic material and rotates in the opposite direction to the brake pad body 115, friction can be generated to clean the surface of the brake pad body 115, thereby preventing impurities from adhering to the surface of the brake pad body 115 and affecting the grinding quality of the brake pad body 115.

[0054] Reference Figure 2-Figure 3 : The grinding mechanism 700 includes a cylinder 701, a mounting plate 702 and a grinding plate 703. The cylinder 701 is installed on an adjacent mounting frame 105. The output end of the cylinder 701 passes through the side wall of the mounting frame 105 to connect the mounting plate 702. The grinding plate 703 is installed on the side wall of the mounting plate 702 away from the cylinder 701.

[0055] The starting cylinder 701 can adjust the distance between the grinding disc 703 and the brake pad body 115, so that the grinding disc 703 can cooperate with the brake pad body 115 during the revolution and rotation to achieve grinding, thereby improving work efficiency.

[0056] Working principle:

[0057] S1, the block 113 and the slot 114 can be matched with the designated position to be installed, and the brake pad body 115 can be installed quickly and easily. It is only necessary to set the docking block and the docking slot matching the shapes of the block 113 and the slot 114 at the designated position and connect them. This installation method is a prior art and will not be described here. The sound insulation layer 111 is used to absorb the noise generated by friction, and the toughness layer 110 and the protective layer 108 are used to improve the wear resistance of the brake pad body 115;

[0058] S2. Strictly screen and control the quality of raw materials, accurately weigh the selected raw material powders and mix them evenly; press the evenly mixed ceramic powders into blanks with a certain shape and strength; put the pressed blanks into a sintering furnace, and sinter them at high temperature by step-by-step temperature rise and fall, so that the ceramic particles can be combined to form a dense ceramic body; grind the sintered ceramic brake pads through a grinding device, and perform processes such as grooving and drilling to ensure the dimensional accuracy and surface finish of the brake pads; finally, check the appearance of the ceramic brake pads to ensure that there are no defects such as cracks and pores, and then spray and print them;

[0059] S3, start the motor 201, drive the connecting shaft 205 to rotate, the connecting shaft 205 drives the first gear 202 to rotate, the first gear 202 drives the first gear ring 203 and the mounting ring 204 to rotate, so as to realize the rotation of the connecting rod 304, the rotation of the connecting rod 304 drives the rotating table 104 and the rotating shaft 303 to rotate, the rotating shaft 303 drives the second gear 302 to rotate on the second gear ring 301 to realize self-rotation, the rotation of the second gear 302 can drive the receiving rod 401 to rotate, the rotation of the receiving rod 401 can drive the first reset spring 404 and the sleeve 403 to rotate, The sleeve 403 drives the workbench 402 and the clamping frame 405 to rotate. The brake pad body 115 is clamped and fixed on the clamping frame 405, so that the brake pad body 115 can rotate. When the workbench 402 rotates to the top of the slide rail 504, the sleeve 403, the workbench 402 and the clamping frame 405 are lifted up through the cooperation of the ball bearing 503 and the slide rail 504. At this time, the unlocking rope 501 pulls the clamping plate 406 back to unlock the brake pad body 115. In this way, the unlocked brake pad body 115 can be taken away by the mechanical claw and a new brake pad body 115 that needs to be polished can be placed.

[0060] S4, the connecting shaft 205 rotates to drive the synchronous belt 602 to rotate, the synchronous belt 602 drives the rotating rod 601 to rotate, and the rotating rod 601 drives the mounting block 604 and the fixed block 605 to rotate. When the brake pad body 115 passes under the fixed block 605, since the fixed block 605 is made of elastic material and rotates in the opposite direction to the brake pad body 115, friction can be generated to clean the surface of the brake pad body 115, so as to prevent impurities from adhering to the surface of the brake pad body 115 and affecting the grinding quality of the brake pad body 115;

[0061] S5. Starting the air cylinder 701 can adjust the distance between the grinding disc 703 and the brake pad body 115, so that the brake pad body 115 can cooperate with the grinding disc 703 during the revolution and rotation of the brake pad body 115 to achieve grinding, thereby improving work efficiency.
