[0020] 2. After the grinding disc is replaced, the placement ring can be placed on the grinding disc. By adjusting the position of the transverse bracket in the sliding groove, the side roller and the side surface of the linkage roller clamp the placement ring.

[0031] When the requirement of the sealing gasket to be polished is different from the mesh number of the grinding disc 6, the screws on the clamp column 7 can be removed to disengage the clamp column 7 from the upper positioning column 5, and then the grinding disc 6 can be taken out from the clamp column 7, replaced with a grinding disc 6 that meets the required mesh number, and the clamp column 7 can be put back, so that the grinding disc 6 can be easily replaced so that the mesh number of the grinding disc 6 meets the requirements of grinding and polishing.

[0032] The fixed plug-in mechanism includes: a second gear 4, which is rotatably mounted on the outer surface of the outer frame 1, and an upper positioning column 5 is fixedly mounted on the side surface of one end of the second gear 4 away from the driving motor 2, and the upper positioning column 5 is engaged with the inner surface of the grinding disc 6, the side surface of the grinding disc 6 is in contact with the side surface of the upper positioning column 5, and the side surface of the upper positioning column 5 is in contact with the side surface of the clamp column 7, the clamp column 7 and the upper positioning column 5 are fixed by a screw, and the side surface of the grinding disc 6 is in contact with the outer surface of the clamp column 7, the grinding disc 6 and the second gear 4 are concentrically designed, and the second gear 4 and the upper positioning column 5 are concentrically designed.

[0033] The rotation of the driving motor 2 will drive the first gear 3 to rotate, and drive the second gear 4 meshing with the first gear 3 to rotate, so that the grinding disc 6 will rotate together to grind the sealing pad placed on the outer surface of the grinding disc 6.

[0034] A first gear 3 is fixedly mounted on the output end of the driving motor 2 , and the first gear 3 is meshed with a second gear 4 , and a diameter of the second gear 4 is smaller than a diameter of the first gear 3 .

[0035] The rotation speed of the second gear 4 is reduced by the diameter difference between the first gear 3 and the second gear 4, so that the rotation speed of the grinding disk 6 will not be too fast, causing the placement ring 9 to fly out of the grinding disk 6, and at the same time, it can prevent the sealing gasket from being polished too much by the grinding disk 6 in a short time.

[0036] A placement ring 9 is provided on the outer surface of the grinding disk 6, and the placement ring 9 is of cylindrical design, and a ball is provided between the placement ring 9 and the grinding disk 6, a sealing gasket is provided inside the placement ring 9, and the side surface of the placement ring 9 fits with the side surface of the sealing gasket, and an upper pressure weight 10 is slidably installed inside the placement ring 9, and the side surface of the upper pressure weight 10 fits with the inner surface of the placement ring 9.

[0039] By adjusting the position of the transverse bracket 12 inside the sliding groove 11, the linkage roller 8 and the side roller 13 clamp the placement ring 9 so that the placement rings 9 of different sizes can be placed on the top of the grinding disk 6. Then, the rotation of the grinding disk 6 drives the linkage roller 8 to rotate, so that the placement ring 9 in contact with the side surface of the linkage roller 8 rotates together, and the sealing gasket placed in the placement ring 9 is rotated and polished, so that the surface of the sealing gasket can fully contact the grinding disk 6 to prevent the sealing gasket from being missed.
