[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 A car sealing plug polishing processing equipment includes a cross-shaped base 1, a load-carrying machine 2 is fixedly installed on the cross-shaped base 1, a first motor 4 is fixedly installed in the cross-shaped base 1, and under the driving action of the first motor 4, a limiting component can limit and fix the granite stone and drive it to rotate horizontally.

[0022] The cross-shaped base 1 and the load-carrying machine platform 2 are provided with a limit assembly for fixing the automobile sealing plug by driving the first motor 4. The limit assembly includes a ball screw 5 rotatably installed between the cross-shaped base 1 and the load-carrying machine platform 2 and fixedly connected to the output end of the first motor 4, and a lifting nut 6 is matched with the ball screw 5. The lifting nut 6 is integrally connected with a guide rod 7 that slides through the cross-shaped base 1 to guide and limit the lifting nut 6 in the vertical direction. A guide long hole 8 is opened in the load-carrying machine platform 2, and an inner clamping piece 9 and an outer clamping piece 10 are symmetrically slidably set in the guide long hole 8. Under the traction of the downwardly moving lifting nut 6, the outer clamping piece 10 moves to one side of the inner clamping piece 9, and the load-carrying machine 2 is lifted. A steering pulley 11 located at the outer side of the outer clamping part 10 is fixedly installed at the lower end of the platform 2, and a traction link 12 is connected between the lifting nut 6 and the outer clamping part 10, and a traction rope 13 passing through the steering pulley 11 is fixedly connected between the inner clamping part 9 and the outer clamping part 10. The traction rope 13 is set in a U-shaped structure to connect the inner clamping part 9 and the outer clamping part 10 through the steering pulley 11, so that the outer clamping part 10 can pull the inner clamping part 9 towards each other, so that the two moving towards each other can be supported and clamped and fixed by the automobile sealing plug, and a reset spring 14 is welded between the inner clamping part 9 and the outer clamping part 10, so that the inner clamping part 9 can reset itself under the tension of the reset spring 14.

[0023] A grinding assembly corresponding to the automobile sealing plug is provided on the load-bearing platform 2, and the grinding assembly includes a second motor 15 integrally connected to the load-bearing truss 3, and the output end of the second motor 15 is fixedly connected to an eccentrically arranged load-bearing support rod 16, a limited position long hole 17 is provided in the load-bearing support rod 16, and a grinder 18 corresponding to the automobile sealing plug is provided in the limited position long hole 17, and the grinder 18 can be fixed in position on the load-bearing support rod 16 by a locking screw, so as to facilitate the position setting of the grinder 18 according to the automobile sealing plug.

[0024] There are four long guide holes 8, and the four long guide holes 8 are equidistantly distributed in the circumferential direction. The number of long guide holes 8 and the inner clamping parts 9 and the outer clamping parts 10 can be increased or decreased according to the size of the automobile sealing plug to ensure all-round position limitation of the automobile sealing plug.
