A support leg 8 is formed on the lower surface of the fixed base plate 1, an L-shaped mounting frame 9 is formed on the rear side of the upper surface of the fixed base plate 1, a slide groove 10 is opened on the upper top plate of the mounting frame 9, a second slider 11 is clamped inside the slide groove 10, a lifting hydraulic cylinder 12 with its head facing downward is embedded in the second slider 11, a horizontal hydraulic cylinder 14 with its head facing backward is embedded inside the upper top plate of the mounting frame 9, the head of the horizontal hydraulic cylinder 14 is connected to the front side of the second slider 11, the horizontal hydraulic cylinder 14 pushes the second slider 11 to slide in the slide groove 10, a grinding block 15 is fixedly connected to the head of the lifting hydraulic cylinder 12, a limiting frame 13 is arranged on the second slider 11, a rod on the limiting frame 13 passes through the second slider 11 and is connected to the upper surface of the grinding block 15, so as to enhance stability;

[0021] When grinding the seal, the lifting hydraulic cylinder 12 is controlled to extend and retract to drive the grinding block 15 to move downward or upward. At this time, the rod body on the limit frame 13 slides up and down in the second slider 11. The height of the grinding block 15 is determined according to the specifications of the seal. Then the horizontal hydraulic cylinder 14 is controlled to extend and retract to drive the second slider 11 to move in the slide groove 10, and the position of the grinding block 15 is changed, so as to facilitate the grinding of seals with different diameters.

[0022] like Figure 1 - Figure 4 As shown, a driving motor 7 is fixedly arranged below the fixed base plate 1, and the output shaft of the driving motor 7 extends upward and penetrates the fixed base plate 1, and a rotating base 6 is fixedly arranged on the upper end of the output shaft of the driving motor 7, and a rectangular groove is opened inside the rotating base 6, and a front-to-back symmetrical support rod 2 is horizontally arranged inside the rotating base 6, and a horizontal bidirectional lead screw 3 is arranged between the two support rods 2, and the left end of the bidirectional lead screw 3 extends and penetrates the rotating base 6, and a left-right symmetrical first sliding block 4 is arranged inside the rotating base 6, and a clamping block 5 with curved left and right sides is formed on the first sliding block 4, the support rod 2 and the bidirectional lead screw 3 penetrate the first sliding block 4, and the first sliding block 4 is screwed with the bidirectional lead screw 3, and a connecting bearing is arranged on the plate body of the fixed base plate 1, and the output shaft of the driving motor 7 is connected to the ground of the rotating base 6 through the connecting bearing, and a wheel disc is formed on the left end of the bidirectional lead screw 3 for easy twisting;

[0023] When installing the seal, when the inner wall of the seal is polished, the seal is placed between the two clamping blocks 5, and the wheel disc is rotated to drive the bidirectional lead screw 3 and the first slider 4 to screw together, so that the two first sliders 4 drive the clamping blocks 5 to approach each other, so that the inner sides of the two clamping blocks 5 are in contact with the outer sides of the seal, and the seal is clamped and fixed. When the outer wall of the seal is polished, the seal is sleeved on the two clamping blocks 5, and the wheel disc is rotated again to drive the bidirectional lead screw 3 and the first slider 4 to screw together, so that the two first sliders 4 drive the clamping blocks 5 to move away from each other, so that the outer sides of the two clamping blocks 5 are in contact with the inner sides of the seal, and the seal is supported and fixed;

[0024] Specific working principle:

[0025] When using the device, when grinding the inner wall of the seal, the seal is placed between the two clamping blocks 5, and the wheel disc is rotated to drive the bidirectional lead screw 3 to screw with the first slider 4, so that the two first sliders 4 drive the clamping blocks 5 to approach each other, so that the inner sides of the two clamping blocks 5 are in contact with the outer sides of the seal, so as to clamp and fix the seal, and control the extension of the lifting hydraulic cylinder 12 to drive the grinding block 15 to move downward and insert into the seal, and determine the height of the grinding block 15 according to the specifications of the seal, and then control the extension of the horizontal hydraulic cylinder 14 to drive the second slider 11 to move in the slide groove 10, and change the position of the grinding block 15 until the grinding block 15 is close to the inner wall of the seal, and start the driving motor 7 to drive the rotating base 6 to rotate. Thereby, the seal on the clamping block 5 is rotated and polished by the polishing block 15. When the inner wall of the seal is polished, the seal is put on the two clamping blocks 5, and then the wheel is rotated to drive the bidirectional screw 3 and the first slider 4 to screw together, so that the two first sliders 4 drive the clamping blocks 5 to move away from each other, so that the outer side surfaces of the two clamping blocks 5 are in contact with the inner side surfaces of the seal, so as to support and fix the seal. The same operation method is adopted to make the polishing block 15 close to the outer side wall of the seal. The polishing block 15 can also be moved to the top of the seal by adjusting the lifting hydraulic cylinder 12 and the horizontal hydraulic cylinder 14, so that the bottom of the polishing block 15 is in contact with the upper end surface of the seal. The movement of the polishing block 15 can be controlled according to actual conditions during the polishing process.
