[0027] Reference Figure 1-6 A polishing device for processing a tripod pin comprises a bottom plate 1 and a ball ring 3. A bracket 12 is fixedly mounted on the surface of the bottom plate 1. A connecting frame 2 is slidably connected to the surface of the bracket 12. A second chuck 13 is fixedly connected to the surface of the bracket 12. A first motor 9 is fixedly mounted on the side wall of the connecting frame 2. A connecting shaft 10 is fixedly mounted on the output shaft port of the first motor 9. The connecting shaft 10 rotates and passes through the connecting frame 2. A first chuck 11 is provided on the surface fixing sleeve 4 of the connecting shaft 10. A first polishing mechanism is provided on the surface of the connecting shaft 10. A second polishing mechanism is provided on the side wall of the second chuck 13. During use, the ball ring 3 to be polished is sleeved on the chuck surface on the connecting shaft 10, and then the claws on the first chuck 11 are used to press against the inner wall of the ball ring 3, so as to achieve the purpose of fixing the ball ring 3. The first motor 9 is started, and the first motor 9 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the first chuck 11 to rotate, and the first chuck 11 drives the ball ring 3 to rotate, so as to benefit The outer surface of the ball ring 3 is polished by the second polishing mechanism. After the polishing of the outer surface is completed, the outer surface of the ball ring 3 is fixed by the claws on the second chuck 13, and the claws on the first chuck 11 are contracted. At this time, the movable frame is moved, and the movable frame drives the connecting shaft 10 to move synchronously. The connecting shaft 10 drives the first chuck 11 and the first polishing mechanism to move synchronously, so that the first chuck 11 is away from the inner wall of the ball ring 3, and the first polishing mechanism is located on the inner wall of the ball ring 3. At this time, the first motor 9 is started, and the first motor 9 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the first polishing mechanism to rotate, and the ball ring 3 is fixed by the second chuck 13, and the first polishing mechanism is located inside the ball ring 3. Therefore, the first polishing mechanism can be used to polish the inside of the ball ring 3. Therefore, the device can achieve the purpose of polishing the outer and inner surfaces of the ball ring 3, reduce the processing steps, improve the processing efficiency, and facilitate operation.

[0028] Furthermore, the first polishing mechanism includes a fixed sleeve 4, which is fixedly mounted on the surface of the connecting shaft 10. A receiving groove 7 is opened on the surface of the fixed sleeve 4. A polishing rod 5 is slidably connected inside the receiving groove 7. A spring 6 is fixedly mounted on the bottom of the polishing rod 5. One end of the spring 6 away from the polishing rod 5 is fixedly connected to the receiving groove 7. When the first polishing mechanism is in use, the connecting shaft 10 will drive the fixed sleeve 4 to move to the inner wall of the ball ring 3, and then the connecting shaft 10 will rotate rapidly under the action of the first motor 9. The connecting shaft 10 will drive the fixed sleeve 4 to rotate synchronously, thereby causing the internal polishing rod 5 to rotate synchronously. The polishing rod 5 will be subjected to centrifugal force when rotating rapidly, thereby causing the polishing rod 5 to extend out of the receiving groove 7, and then the inner wall of the ball ring 3 is polished by the polishing rod 5. When the connecting shaft 10 stops rotating, the fixed sleeve 4 will also stop rotating, thereby causing the polishing rod 5 to not be subjected to centrifugal force, and then the polishing rod 5 can be hidden in the receiving groove 7 under the pulling force of the spring 6, thereby avoiding the phenomenon that the polishing rod 5 protrudes from the fixed sleeve 4 and the ball ring 3 cannot be smoothly mounted on the surface.

[0029] Furthermore, the second polishing mechanism includes a fixed plate 14, which is fixedly connected to the second chuck 13. A mounting frame 18 is provided on the top of the fixed rod. The mounting frame 18 is a "U"-shaped structure. A polishing roller 17 is rotatably connected between the two arms of the mounting frame 18. A second motor 19 is fixedly installed on the side wall of the mounting frame 18. The output shaft port of the second motor 19 is fixedly connected to the polishing roller 17. When the second polishing mechanism is in use, the ball ring 3 is tightened and fixed from the inside by the claws of the first chuck 11. At this time, the fixed sleeve 4 is not inside the ball ring 3, so even if the polishing rod 5 is forced to extend out of the accommodating groove 7, it will not act on the ball ring 3. After the ball ring 3 is fixed by the claws of the first chuck 11, the second chuck 13 is released from the fixation of the ball ring 3. At this time, there is no contact with the outer surface of the ball ring 3. Then, the first motor 9 is started, and the first motor 9 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the first chuck 11 to rotate, and the first chuck 11 drives the ball ring 3 to rotate. At this time, the polishing roller 17 is in contact with the outer surface of the ball ring 3, thereby achieving the purpose of polishing the outer surface.

[0030] Furthermore, a second electric telescopic rod 15 is fixedly installed on the surface of the fixed plate 14, and the output end port of the second electric telescopic rod 15 is fixedly connected to the mounting frame 18. A vertical rod 16 is fixedly installed at the bottom of the mounting frame 18, and the vertical rod 16 slides through the fixed plate 14. The second electric telescopic rod 15 is provided to enable the mounting frame 18 and the polishing roller 17 to be moved, so that when the polishing roller 17 is needed, the polishing roller 17 is brought into contact with the outer surface of the ball ring 3, and when the polishing roller 17 is not needed, the polishing roller 17 is moved away from the ball ring 3 for easy operation. The provision of the vertical rod 16 can connect the mounting frame 18, thereby avoiding the phenomenon that the mounting frame 18 and the fixed plate 14 are only connected through the second electric telescopic rod 15, so that the second electric telescopic rod 15 is damaged by other forces.

[0031] Furthermore, circular holes are provided on the surfaces of the bracket 12 and the second chuck 13, and the sizes of the first chuck 11 and the fixing sleeve 4 are smaller than the circular holes. The circular holes can enable the connecting shaft 10, the first chuck 11 and the fixing sleeve 4 to move smoothly in the horizontal direction, avoiding the phenomenon that they are restricted by the bracket 12 and the second chuck 13 and cannot move, affecting the normal operation of other parts.

[0032] Furthermore, a first electric telescopic rod 8 is fixedly installed on the surface of the bracket 12, the connecting frame 2 is an "L"-shaped structure, and the output end port of the first electric telescopic rod 8 is fixedly connected to the connecting frame 2. By setting the first electric telescopic rod 8, the movement of the connecting frame 2 can be electrically controlled, thereby achieving the purpose of electrically controlling the horizontal movement of the connecting shaft 10, the fixed sleeve 4 and the first chuck 11.

[0033] In summary, during use, the ball ring 3 to be polished is sleeved on the chuck surface on the connecting shaft 10, and then the claws on the first chuck 11 are used to press against the inner wall of the ball ring 3, so as to achieve the purpose of fixing the ball ring 3, and the first motor 9 is started, and the first motor 9 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the first chuck 11 to rotate, and the first chuck 11 drives the ball ring 3 to rotate, so as to use the second polishing mechanism to polish the outer surface of the ball ring 3. When the outer surface polishing is completed, the outer surface of the ball ring 3 is fixed by the claws on the second chuck 13, and the claws on the first chuck 11 are contracted, and at this time, the movable frame is moved, and the movable frame drives the connecting shaft 10 to move synchronously, and the connecting shaft 10 drives the first chuck 11 and the first polishing mechanism to move synchronously. Move the first chuck 11 away from the inner wall of the ball ring 3, and make the first polishing mechanism located on the inner wall of the ball ring 3. At this time, start the first motor 9, and the first motor 9 drives the connecting shaft 10 to rotate, and the connecting shaft 10 drives the first polishing mechanism to rotate, while the ball ring 3 is fixed by the second chuck 13, and the first polishing mechanism is located inside the ball ring 3, so the first polishing mechanism can be used to polish the inside of the ball ring 3. Therefore, the device can achieve the purpose of polishing the outer surface and inner surface of the ball ring 3, reduce the processing steps, improve the processing efficiency, and facilitate the operation. When the first polishing mechanism is in use, the connecting shaft 10 will drive the fixing sleeve 4 to move to the inner wall of the ball ring 3, and then the connecting shaft 10 will rotate rapidly under the action of the first motor 9. The connecting shaft 10 will drive the fixed sleeve 4 to rotate synchronously, thereby causing the internal polishing rod 5 to rotate synchronously. The polishing rod 5 will be subjected to centrifugal force when rotating rapidly, thereby causing the polishing rod 5 to extend out of the receiving groove 7, and then the polishing rod 5 is used to polish the inner wall of the ball ring 3. When the connecting shaft 10 stops rotating, the fixed sleeve 4 will also stop rotating, so that the polishing rod 5 will not be subjected to centrifugal force, and then the polishing rod 5 can be hidden in the receiving groove 7 under the pulling force of the spring 6, avoiding the polishing rod 5 protruding from the fixed sleeve 4 and causing the ball ring 3 to be unable to be smoothly mounted on the surface. When the second polishing mechanism is in use, the ball ring 3 is fixed by the claws of the first chuck 11 from the inside by being pressed and fixed. At this time, the fixed sleeve 4 is not inside the ball ring 3. Therefore, even if the polishing rod 5 is forced to extend out The accommodating groove 7 will not act on the ball ring 3 either. After the ball ring 3 is fixed by the claws of the first chuck 11, the second chuck 13 is released from the fixation of the ball ring 3. At this time, there is no contact with the outer surface of the ball ring 3. The first motor 9 is started again, and the first motor 9 drives the connecting shaft 10 to rotate. The connecting shaft 10 drives the first chuck 11 to rotate. The first chuck 11 drives the ball ring 3 to rotate. At this time, the polishing roller 17 is in contact with the outer surface of the ball ring 3. The second motor 19 is started again, and the second motor 19 drives the polishing roller 17 to rotate, so as to achieve the purpose of polishing the outer surface. The mounting frame 18 and the polishing roller 17 can be moved by setting the second electric telescopic rod 15, and then when the polishing roller 17 is needed, the polishing roller 17 is in contact with the outer surface of the ball ring 3.When the polishing roller 17 is not needed, the polishing roller 17 is moved away from the ball ring 3 to facilitate operation. The vertical rod 16 can connect the mounting frame 18 to avoid the mounting frame 18 and the fixing plate 14 being connected only by the second electric telescopic rod 15, which may cause the second electric telescopic rod 15 to be damaged by other forces. The circular hole can be used to enable the connecting shaft 10, the first chuck 11 and the fixing sleeve 4 to move smoothly in the horizontal direction, avoiding the phenomenon that the connecting shaft 10, the first chuck 11 and the fixing sleeve 4 are restricted by the bracket 12 and the second chuck 13 and cannot move, which may affect the normal operation of other parts. The first electric telescopic rod 8 can be used to electrically control the movement of the connecting frame 2, thereby achieving the purpose of electrically controlling the horizontal movement of the connecting shaft 10, the fixing sleeve 4 and the first chuck 11.
