[0030] A controller 7 is fixedly installed on the outer wall of the base plate 1, and a connecting plate 9 is fixedly installed on the top of the circular ring 3. A long rod 8 is fixedly installed on the outer wall of the connecting plate 9, and a clamping assembly 6 is provided on the outer wall of the long rod 8. A retainer body 5 is provided on the outer wall of the clamping assembly 6. Here, by setting the controller 7 on the outer wall of the base plate 1, centralized control of various components of the equipment can be achieved, making operation convenient and efficient. The setting of the connecting plate 9 and the long rod 8 provides stable support for the clamping assembly 6, ensuring the stability of the retainer body 5 during the processing, which is conducive to improving the surface treatment quality.

[0031] The outer wall of the motor 401 is slidably connected to the inner wall of the slide rail 406. The outer wall of the round shaft 402 is in contact with the outer wall of the slide rail 406. The outer wall of the arc plate 403 is slidably connected to the top of the gear ring 405. The top of the circular gear 404 and the bottom of the round shaft 402 are fixedly installed. The bottom of the circular gear 404 is slidably connected to the top of the circular ring 3. The side of the grinding block 407 away from the arc plate 403 is in contact with the outer wall of the cage body 5. Here, the sliding connection design between the motor 401 and the slide rail 406 allows the motor 401 to move along the slide rail 406, thereby driving the round shaft 402 and the arc plate 403 to move, realizing the comprehensive grinding of the outer wall of the cage body 5 by the grinding block 407. The meshing of the circular gear 404 and the gear ring 405 and the related sliding connection structure ensure the stability and reliability of the grinding process, and improve the grinding efficiency and quality.

A circular plate 603 is rotatably connected to the bottom of the second circular gear 602. A third circular gear 604 meshes with the outer wall of the second circular gear 602. Here, the motor 601 in the clamping assembly 6 drives the second circular gear 602 to rotate, providing a power source for subsequent clamping actions. This gear transmission method has high transmission accuracy and good stability, and can accurately control the clamping force and position, ensuring that the cage body 5 will not shift during the surface treatment process.

[0033] A cylinder 605 is slidably connected to the inner wall of the circular gear 604. A slider 606 is fixedly installed at the bottom of the cylinder 605, and a clamping plate 607 is fixedly installed on the outer wall of the slider 606. A support plate is fixedly installed on the side of the motor 601 away from the circular gear 602. At this point, the sliding connection between the circular gear 604 and the cylinder 605, and the sliding connection between the slider 606 and the circular plate 603, allows the clamping plate 607 to slide radially on the circular plate 603, thereby achieving adaptive clamping of cage bodies 5 of different sizes. The limiting plate prevents the cylinder 605 from detaching from the circular gear 604, ensuring the safety and reliability of the clamping structure.

[0034] A circular gear 604 is rotatably connected to the top of the circular plate 603, and a slider 606 is slidably connected to the inner wall of the circular plate 603. The outer wall of the clamping plate 607 is engaged with the inner wall of the cage body 5. Here, the evenly distributed design of the five sets of cylinders 605, sliders 606, and clamping plates 607 can stably clamp the inner wall of the cage body 5 from multiple directions, so that the cage body 5 is subjected to uniform force during the grinding process, avoiding deformation caused by uneven force, and further improving the precision and quality of surface treatment.

[0035] A limiting plate is fixedly installed on the side of cylinder 605 away from slider 606, and the bottom of the limiting plate contacts the upper surface of circular gear 604. There are five sets of cylinder 605, slider 606, and clamping plate 607, and all five sets of cylinder 605, slider 606, and clamping plate 607 are installed on the inner wall of cage body 5. Here, the silicone protective pad on the top of base plate 1 can effectively buffer the vibration generated during equipment operation, reduce damage to base plate 1 and other components, and extend the service life of equipment; the electric push rod can realize the adjustment of the height of clamping assembly 6 to adapt to cage body 5 of different heights, enhancing the versatility and applicability of equipment.

[0036] A protective pad made of silicone is fixedly installed on the top of the base plate 1. An electric push rod is fixedly installed on the side of the connecting plate 9 away from the long rod 8. The controller 7 is electrically connected to the electric push rod, motor 601, and motor 401, and the telescopic end of the electric push rod is fixedly installed on the upper surface of the circular plate 603. Here, the electrical connection between the controller 7 and the electric push rod, motor 601, and motor 401 realizes the automated control of the equipment. Operators can accurately set the operating parameters of each component through the controller 7, improving production efficiency and product quality stability. At the same time, this automated control method reduces manual intervention, lowering the labor intensity and operational risks for operators.

[0037] Working Principle: The cage body 5 to be processed is placed on top of the base plate 1. The electric push rod is activated by the controller 7, causing the clamping assembly 6 to descend and enter the inner wall of the cage body 5. At this time, the controller 7 controls the motor 601 to start. The output shaft of the motor 601 drives the second circular gear 602 to rotate synchronously. The second circular gear 602 drives the third circular gear 604 to rotate. At this time, the cylinder 605 is driven to slide on the inner wall of the circular plate 603 under the rotation of the third circular gear 604. Thus, the cylinder 605 can drive the slider 606 to slide on the inner wall of the circular plate 603. The slider 606 can then drive the clamping plate 607 to move. When the clamping plate 607 clamps the cage, the current of the motor 601 increases. The controller 7 detects the current threshold and cuts off the power. The self-locking characteristic of the gear transmission ensures that the expanded state is locked without continuous power supply. Adaptive clamping of the inner wall of the cage body 5 of different sizes is now achieved. Meanwhile, the five clamping structures ensure that the cage body 5 is subjected to uniform force during the polishing process, preventing deformation. During the polishing stage, the controller 7 activates the motor 401 in the polishing assembly 4. The output of the motor 401 drives the circular shaft 402 to rotate. The circular gear 404 mounted at the bottom of the circular shaft 402 meshes with the gear ring 405. Simultaneously, the top of the circular gear 404 is fixed to the circular shaft 402, while its bottom slides against the top of the circular ring 3. Driven by the motor 401, the circular gear 404 rotates along the gear ring 405, thereby driving the arc-shaped plate 403, which is rotatably connected to the circular shaft 402, to move. Therefore, during the movement of the arc-shaped plate 403, the polishing block 407 fixed to its outer wall can thoroughly polish the outer wall of the cage body 5. This ensures the stability and reliability of the polishing process, improving polishing efficiency and quality.
