[0027] Specifically, the utility model realizes the adjustment of the size of the grinding table 32 by setting a plurality of groups of meshing components, which not only improves the production efficiency, but also enables the grinder to process larger and more specifications of sealing rings, greatly improving the practicality of the grinder; the normal working process of the grinder: first, the sealing ring is placed in the corresponding carrier, and then the upper grinding disc 2 on the base 1 is rotated to the top of the lower grinding disc 3, and then the upper grinding disc 2 is moved downward so that the grinding surface of the upper grinding disc 2 is pressed against the top surface of the sealing ring, and the machine is started to grind the upper and lower surfaces of the sealing ring.

[0028] Furthermore, the meshing assembly includes a first circular plate 4 and a second circular plate 5. The first circular plate 4 is sleeved on the outside of the lower grinding disc 3, and the second circular plate 5 is sleeved on the outside of the first circular plate 4. The first circular plate 4 and the second circular plate 5 are both connected to the grinding table 32 through a first spring 7. A circle of first meshing columns 41 are fixedly arrayed on the first circular plate 4, and a circle of second meshing columns 51 are fixedly arrayed on the second circular plate 5.

[0029] Specifically, one end of the first spring 7 is fixedly connected to the bottom of the grinding table 32, and the other end of the first spring 7 is fixedly connected to the first circular plate 4 or the second circular plate 5. A group of meshing components can also be set outside the second circular plate 5, and several groups of meshing components can be designed according to needs. The grinding table 32 is provided with holes for the first meshing column 41 and the second meshing column 51 to pass through. The first meshing column 41 or the second meshing column 51 is used to mesh with the carrier of the sealing ring to realize the self-rotation of the carrier. The holes on the grinding table 32 can be used to discharge the grinding liquid on the grinding platform.

[0030] Furthermore, the lifting assembly includes a first lifting plate 42 and a second lifting plate 52, the lower bottom surfaces of the first engaging column 41 and the second engaging column 51 are both formed into contact surfaces with a horizontal section 101 and a smooth curved section 102, and the upper bottom surfaces of the first lifting plate 42 and the second lifting plate 52 are both formed with contact surfaces respectively engaged with the first engaging column 41 and the second engaging column 51.

[0031] Specifically, when the horizontal section 101 on the lower bottom surface of the first circular plate 4 is aligned with the horizontal section 101 on the upper bottom surface of the first lifting plate 42, the first spring 7 is compressed, and the first engaging column 41 passes through the grinding table 32 and engages with the outer edge of the carrier of the sealing ring. When more sealing rings need to be processed or a larger sealing ring needs to be processed, a larger carrier needs to be replaced, and the grinding area at the top of the grinding table 32 needs to be adjusted, that is, the first lifting plate 42 is rotated so that the horizontal section 101 on the first lifting plate 42 is aligned with the smooth curved surface section 102 on the first circular plate 4, so that the first circular plate 4 is lowered as a whole, and the first lifting plate 4 is lowered. An engaging column 41 is retracted under the grinding table 32, and then the second lifting plate 52 is rotated to align the horizontal section 101 on the second lifting plate 52 with the horizontal section 101 on the second annular plate 5, so that the second engaging column 51 passes through the grinding table 32 and engages with the outer edge of the carrier of the sealing ring; the utility model allows the engaging column to pass through the grinding table 32 by rotating the lifting component, so as to control the area of ​​the grinding table 32 used for grinding, wherein the lifting component lifts the engaging component in a tightly fitting manner, so that the engaging component can move upward smoothly, and then the engaging component smoothly passes through the grinding table 32.

[0032] Furthermore, a slide groove 31 is provided on the lower grinding disc 3, and a first clamping groove 421 and a second clamping groove 521 are respectively provided in the first lifting plate 42 and the second lifting plate 52, the first clamping groove 421 and the second clamping groove 521 are communicated with the slide groove 31, a rotating rod 6 is inserted into the slide groove 31, an inner groove 62 is provided in the rotating rod 6, a clamping block 8 is slidably provided in the inner groove 62, the clamping block 8 is connected to the inner wall of the inner groove 62 through a second spring 9, a steering shaft 64 is provided in the inner groove 62, a steel wire rope 63 is fixedly connected to the lower end of the clamping block 8, the steel wire rope 63 passes through the steering shaft 64 and then passes through the rotating rod 6 to connect with the limiting buckle 61.

[0033] Specifically, first hold one end of the rotating rod 6 and hook the limiting buckle 61 with your fingers, so that the block 8 can overcome the elastic force of the second spring 9 and retract into the inner groove 62 under the pulling of the wire rope 63. One end of the second spring 9 is fixedly connected to the bottom end of the block 8, and the other end is fixedly connected to the inner wall of the inner groove 62. Then, insert the rotating rod 6 into the slide groove 31. After the rotating rod 6 is inserted into the bottom of the slide groove 31, release the limiting buckle 61, and slowly drag the rotating rod 6 outward until the block 8 slides into the first clamping groove 421 under the elastic force of the second spring 9. Then slide the rotating rod 6 along the slide groove 31.
