[0028] Further, as Figure 1 、 Figure 4 、 Figure 5As shown, the bottom plate 1 end fixedly connected with a fixed sleeve 2; the fixed sleeve 2 inner wall fixedly connected with a rotating motor 21; the rotating motor 21 output end is provided with a connecting column 22; the connecting column 22 inner wall is provided with an embedded groove 23; the connecting column 22 side wall is fixedly connected with a covered edge sleeve 24; the connecting column 22 inner wall is slidably connected with a group rotating sleeve 25; the group rotating sleeve 25 side wall is fixedly connected with an embedded rubber sleeve 26; the embedded groove 23 inner wall is slidably connected with an embedded rubber sleeve 26; the group rotating sleeve 25 is provided with a ball release sleeve frame 27; the ball release sleeve frame 27 and group rotating sleeve 25 are slidably connected; when the ball head is placed on the ball release sleeve frame 27 and polished in the process, the connecting column 22 is driven to rotate by starting the rotating motor 21, so that the group rotating sleeve 25 can be driven to rotate, and in the process of rotating, the group rotating sleeve 25 bottom is wrapped and supported by the covered edge sleeve 24, which reduces the shaking of the group rotating sleeve 25 when rotating, and the clamping groove effect between the embedded rubber sleeve 26 connected by the group rotating sleeve 25 and the embedded groove 23 can improve the fixing effect of the group rotating sleeve 25, thereby improving the stability of the group rotating sleeve 25 when rotating, and further improving the stability of the ball head when rotating by the ball release sleeve frame 27 when the group rotating sleeve 25 rotates, which can make the polishing tool fully contact with each part of the surface of the ball head during polishing, avoid local over-polishing or polishing, ensure that the entire surface of the ball head can be uniformly processed, so as to obtain consistent surface finish and precision, and improve the overall quality of the ball head.

[0029] Further, as shown in the drawings, Figure 5 The inner wall of the group rotating sleeve 25 is fixedly connected with a second floating sleeve column 3; the inner wall of the second floating sleeve column 3 is slidably connected with a floating rod 31; the floating rod 31 is fixedly connected with the ball release sleeve frame 27; the side wall of the second floating sleeve column 3 is fixedly connected with a second spring 32; the second spring 32 is fixedly connected with the ball release sleeve frame 27; when polishing the ball head, the second floating sleeve column 3 and the floating rod 31 composed of the piston movement and the second spring 32 set below the ball release sleeve frame 27 can automatically adjust the pressure on the ball head during the work, which can automatically adjust the position and support force of each support point below the component according to the size, direction and change of the acting point of the force on the top of the ball head, so as to evenly distribute the force on the top to the support surface of the entire bottom of the ball head, avoid local overloading and deformation or damage of the ball head, and ensure the stability and integrity of the ball head during processing or use.

[0030] Further, as shown in the drawings, Figure 4 , Figure 5As shown, the rotating sleeve 25 has symmetrically formed sliding grooves 4 on its sidewalls; the edging sleeve 24 has symmetrically fixed positioning blocks 41 on its sidewalls; the inner sidewall of the positioning block 41 is slidably connected to a sliding handle 42; the sliding handle 42 is slidably connected to the edging sleeve 24 and the sliding grooves 4; a third spring 43 is fixedly connected to the sidewall of the positioning block 41; the third spring 43 is fitted into the middle of the sliding handle 42; during operation, by pulling the sliding handle 42 outward, it can be disengaged from the edging sleeve 24 and the rotating sleeve 25, and the third spring 43 is compressed. At this time, the operator can replace different rotating sleeves 25 and connected parts according to different ball heads. After the replacement is completed, the tension on the sliding handle 42 is released, and the rebound force of the third spring 43 can drive the sliding handle 42 to slide inward, thereby restricting and fixing the connection between the assembly sleeve 25 and the edge sleeve 24, thus completing the replacement of the assembly sleeve 25 and its connected placement device. This design, with its convenient disassembly structure, facilitates the replacement of the assembly sleeve and its connected placement device. The convenient replacement of the placement device ensures that ball heads of various sizes can be accurately and stably fixed, allowing the processing equipment to better adapt to the size of the ball head, meet the processing needs of different ball heads, and improve the processing accuracy and quality.

[0031] Furthermore, such as Figure 6 As shown, the fixed sleeve 2 has multiple sets of support plates 5 fixedly connected to its side wall; the support plates 5 are arranged in a circumferential array; a collection box 51 is fixedly connected to the end of the support plate 5; during operation, waste and debris are generated during the polishing of the ball head. The collection box 51 can collect the waste and debris, thereby reducing the entry of hard particles in the waste and debris into the transmission system, bearings and other critical parts of the equipment. This design can reduce the wear of equipment parts by collecting waste and debris, reduce the maintenance and replacement costs of the equipment, and improve the reliability and stability of the equipment.

[0032] Furthermore, such as Figure 6 As shown, a sliding groove 6 is provided on the side wall of the collection box 51; a brush plate 61 is slidably connected to the side wall of the sliding groove 6; during operation, by manipulating the brush plate 61 to slide within the sliding groove 6, the brush plate 61 can clean the waste and debris retained on the side wall of the collection box 51, allowing the collection box to maintain a larger effective space and extend its service life. This design, through the set trajectory brush plate, can clean the waste and debris retained on the side wall of the collection box 51, thereby improving waste collection efficiency and ensuring smooth processing.

[0033] Furthermore, such as Figure 6As shown, the side wall of the collection box 51 is provided with a drop-out opening 7; during operation, the waste and debris inside the collection box 51 can be discharged through the drop-out opening 7, collected, and taken out to the outside for recycling. This design facilitates the removal of waste and debris through the drop-out opening, thereby improving the recycling rate.

[0034] Working principle: Activating the electric push rod 14 pushes the servo motor 15 downwards, allowing the clamping shell 16 to enclose the ball head below. Once the clamping shell 16 has enclosed the ball head, activating the servo motor 15 provides kinetic energy to the polishing disc 103, causing it to rotate. This allows for further grinding and polishing of the ball head surface. During the grinding and polishing process, the floating block 101 slides inside the first floating sleeve 19, creating a piston motion. The gas pressure effect of the piston motion provides adaptive motion for the floating block 101, while the first spring 104 buffers and adjusts this adaptive motion, improving its stability. This allows the polishing disc 103 to adjust according to the actual shape of the ball head surface. The system automatically adjusts the grinding position and pressure based on changes in curvature and real-time conditions during processing. Simultaneously, the rotating ball 102 and floating block 101 connected to the polishing disc 103 can rotate, allowing for automatic angle adjustment of the polishing disc 103. During the grinding and polishing process, the rotating motor 21 drives the connecting column 22 to rotate, which in turn drives the rotating sleeve 25 to rotate. During rotation, the edge sleeve 24 provides support and wrapping to the bottom of the rotating sleeve 25, reducing vibration. Furthermore, the locking effect between the embedded rubber sleeve 26 and the embedded groove 23 connected to the rotating sleeve 25 enhances its fixation, thereby improving the overall performance of the rotating sleeve. The stability of the rotating sleeve 25 during rotation is improved, thereby enhancing the stability of the ball head rotation via the ball placement sleeve 27. When the ball head is being polished, the force is applied above the ball head. The piston movement composed of the second floating sleeve column 3 and floating rod 31 located below the ball placement sleeve 27, along with the second spring 32, adaptively adjusts the pressure applied to the ball head from above. Pulling the sliding column handle 42 outwards disengages it from the edge sleeve 24 and the rotating sleeve 25, compressing the third spring 43. At this point, the operator can replace different rotating sleeves 25 and connected placement devices according to different ball heads. After replacement, releasing the pull on the sliding column handle 42 allows the rebound force of the third spring 43 to move the sliding column handle 42 towards... The inner sliding mechanism allows for the restriction and fixation of the rotating sleeve 25 and the edge sleeve 24, thereby completing the replacement of the rotating sleeve 25 and its connected placement device. During the polishing of the ball head, waste and debris are generated. The collection box 51 can collect the waste and debris, thereby reducing the entry of hard particles in the waste and debris into the transmission system, bearings and other critical parts of the equipment. By controlling the brush plate 61 to slide in the sliding groove 6, the brush plate 61 can clean the waste and debris retained on the side wall of the collection box 51, allowing the collection box to maintain a large effective space and extend its service life. The drop-out port 7 facilitates the discharge of waste and debris from the inside of the collection box 51 for collection and external recycling.
