A grinding block 11 is installed at one end, and the inner circumference arc size of the grinding block 11 corresponds to the outer circumference size of the rubber sleeve 33. The top end of the second rotating rod 15 extends to the inner circumference of the main frame 1 and is connected to a turntable 16. A grinding sleeve 17 is installed on the outer wall of the turntable 16. The outer circumference size of the grinding sleeve 17 corresponds to the inner circumference size of the rubber sleeve 33. The grinding block 11 is located on both sides of the outer circumference of the grinding sleeve 17. Second telescopic members 25 are installed on both sides of the main frame 1. The second telescopic members 25 are set at the same height as the turntable 16. The end of the second telescopic member 25 close to the turntable 16 is connected with an extrusion block 26. The main frame 1, the rotating plate 8, the frame plate 9, and the turntable 16 are all made of steel structures. The length of the frame plate 9 is greater than the length of the rubber sleeve 33. The frame plate 9 has a certain elasticity to cooperate with the extrusion block 26. When the rubber sleeve 33 is deburred, the rubber sleeve 33 is placed between the grinding block 11 and the grinding sleeve 17. The outer wall of the rubber sleeve 33 fits with the inner wall of the grinding block 11, and the inner wall of the rubber sleeve 33 fits with the outer wall of the grinding sleeve 17. The structural strength of the frame plate 9 satisfies that when the rotating plate 8 rotates, the grinding block 11 1 will not separate from the inner wall of the rubber sleeve 33. A lifting support assembly 34 is installed at the bottom of the main frame 1. The lifting support assembly 34 is used to support the bottom end of the rubber sleeve 33 and can adjust the height position of the rubber sleeve 33 when the rubber sleeve 33 is deburred.

A grinding disc 32 is connected to the bottom output end of the third driving member 31. The outer diameter of the grinding disc 32 is larger than the outer diameter of the rubber sleeve 33 and smaller than the distance between the two frame plates 9, so that the grinding disc 32 can enter between the two frame plates 9.

[0027] Example 2: See Figure 1 , Figure 2On the basis of the first embodiment, mounting frames 2 are connected to both sides of the bottom end of the main frame 1, and the bottom end of the mounting frame 2 is mounted on the top of the bottom plate 3 by a first bolt 5. A shock-absorbing pad 4 is provided at the connection between the mounting frame 2 and the bottom plate 3.

[0028] See also Figures 1 to 3 The top end of the frame plate 9 is connected with a right-angled mounting portion 12 , and the mounting portion 12 is detachably mounted on the bottom end of the rotating plate 8 via a second bolt 13 .

[0029] See also Figure 1 , Figure 3 , Figure 4 The outer wall of the grinding block 11 and the inner wall of the grinding sleeve 17 are both provided with a plug-in portion 19, and the inner wall of the arc plate 10 and the outer wall of the turntable 16 are both provided with an embedding groove 18 that cooperates with the plug-in portion 19. The embedding groove 18 has only a top opening for inserting the plug-in portion 19. The bottom and top corners of the grinding block 11 and the grinding sleeve 17 are both set to be arc-shaped, so that the end of the rubber sleeve 33 can be inserted between the grinding block 11 and the grinding sleeve 17.

[0030] Working principle: When in use, the height of the circular plate 23 is adjusted by telescoping the first telescopic member 21, so that the top of the support rod 24 is in the middle between the inner wall of the grinding block 11 and the outer wall of the grinding sleeve 17, and the bottom end of the rubber sleeve 33 is placed on the top of the support rod 24. At this time, a small part of the bottom end of the rubber sleeve 33 is between the grinding block 11 and the grinding sleeve 17, but the bottom end of the rubber sleeve 33 does not protrude below the grinding block 11. At this time, the first driving member 6 drives the first rotating rod 7 to rotate, thereby driving the frame plate 9 and the grinding block 11 to rotate, and at the same time, the second driving member 14 drives the second rotating rod 15 to rotate, thereby driving the turntable 16 and the grinding sleeve 17 to rotate. The first rotating rod 7 and the second rotating rod 15 have opposite directions. The inner and outer walls of the rubber sleeve 33 are deburred respectively by the rotation of the grinding sleeve 17 and the grinding block 11. After most of the rubber sleeve 33 moves to the bottom of the turntable 16, a small part of the top of the rubber sleeve 33 The first and second drive members 6 and 14 are closed, and the position of the frame plate 9 is adjusted so that it does not block the movement of the working box 30. The extrusion block 26 is driven to move by the second telescopic member 25. The extrusion block 26 squeezes the outer wall of the frame plate 9 so that the arc plate 10 is close to the turntable 16. The rubber sleeve 33 is clamped and fixed by the grinding block 11 and the grinding disk 32. Then, the working box 30 is moved between the two frame plates 9 and is directly above the rubber sleeve 33 by the extension of the fourth telescopic member 29. The grinding disk 32 is driven to rotate by the third drive member 31. The working box 30 is driven to move slowly downward by the third telescopic member 27, thereby driving the bottom end of the grinding disk 32 to contact with the top end of the rubber sleeve 33 to deburr the top end of the rubber sleeve 33. Then, the rubber sleeve 33 is taken out. After resetting the equipment, the top and bottom ends of the rubber sleeve 33 are reversed and the above steps are repeated to achieve deburring of the other end of the rubber sleeve 33.
