[0002] Polishing equipment is widely used in many industries such as arts and crafts, car detailing, and electronic component manufacturing to improve the surface quality of products. As the core component of polishing equipment, the working state of the polishing disc directly affects the polishing effect. However, traditional polishing equipment has a series of problems in the design and installation of the polishing disc, highlighting the importance and urgency of the innovative point of easy disassembly of the polishing disc.

[0003] Polishing equipment is a type of mechanical equipment that uses physical and chemical processes to grind and repair the surface of a workpiece in order to improve its smoothness and flatness and remove surface defects.

[0004] As usage time increases, polishing discs inevitably wear down. Traditionally, polishing discs are usually connected to the main body of the equipment through complex screw fastening, strong adhesive bonding, or special clip nesting. To replace the polishing disc, maintenance personnel not only need to remove multiple layers of protective structure, but may also need to use professional tools to loosen screws that have rusted or been overtightened due to long-term use. The operation process is extremely cumbersome, time-consuming, and labor-intensive, which reduces the efficiency of polishing disc maintenance and repair, and thus reduces the practicality of the equipment.

Second limiting block grooves 21 are provided on both inner walls of the polishing disc mounting groove 18. Limiting blocks 19 are slidably connected inside both second limiting block grooves 21. First limiting block grooves 20 are provided on both outer walls of the upper end of the polishing disc 6. The two limiting blocks 19 are close to the first limiting block groove 14. One end of each limiting block groove 20 slides into the interior of the polishing disc mounting groove 18 and contacts the inner wall of the corresponding first limiting block groove 20. The outer walls of the four conical blocks on the polishing disc 6 are slidably connected to the interior of the four conical grooves inside the polishing disc mounting groove 18. Rotary threaded sleeves 4 are rotatably connected to the interior of the two protruding plates on both sides of the mounting base 3. A rotating threaded rod 22 is provided inside the second limiting block groove 21. One end of the rotating threaded rod 22 is rotatably connected to the outer wall of the limiting block 19. The end of the rotating threaded sleeve 4 near the limiting block 19 extends rotatably into the interior of the second limiting block groove 21. The outer wall of the end of the rotating threaded rod 22 away from the limiting block 19 is threadedly connected to the interior of the rotating threaded sleeve 4. A second motor 10 is installed on the outer wall of the fixed plate on one side of the sliding support plate 9. The output end of the second motor 10 extends rotatably into the groove on the lower surface of the sliding support plate 9 and is fixedly connected to one end of the second threaded rod 14.

[0034] Among them, cylinders 11 are installed on the outer walls of the two support plates at the upper end of the support mounting base 1. The output ends of the two cylinders 11 slide to the outside of the support plates and are fixedly connected to the outer wall of one side of the corresponding clamping block 12. Two dust collection boxes 8 are fixedly connected to the upper surfaces of the sliding support plate 9 on both sides. A first threaded rod 13 is rotatably connected to the groove inside the outer wall of the rear support column of the support mounting base 1. The sliding support plate 9 is threadedly connected to the outer wall of the first threaded rod 13. The ends of the two dust collection boxes 8 near the sliding support plate 9 are fixedly extended to the outside of the sliding support plate 9. The upper surface of the rear support column of the support mounting base 1 is equipped with cylinders 11. The first motor 7 is equipped with an output end that extends to the groove on the outer wall of the support column and is fixedly connected to one end of the first threaded rod 13. Two sliding rods that are slidably connected to the outer walls of the two support plates on the support mounting base 1 extend to the outside of the support plates and are fixedly connected to the outer walls of the corresponding clamping blocks 12. Two sliding blocks 5 are slidably connected to the lower outer walls of the dust collection boxes 8 through arc-shaped grooves. The sliding blocks 5 are installed on the dust collection boxes 8 by bolts. A fan 17 is installed inside the upper end of the dust collection box 8. An activated carbon adsorption plate 2 is fixedly connected to the inner wall of the sliding block 5.

[0035] Furthermore, when using the device, it is started by connecting to an external power source, which activates the two cylinders 11 on the support mounting base 1. The output ends of the cylinders 11 push the two clamping blocks 12 to move towards each other. The two sliding rods act as guides to ensure that the clamping blocks 12 move smoothly, ultimately clamping the craft gift firmly in the middle, preparing for subsequent surface treatment. Then, the first motor 7 is started, and its output end drives the first threaded rod 13 to rotate. Since the sliding support plate 9 is threadedly connected to the first threaded rod 13, the rotation of the first threaded rod 13 causes the sliding support plate 9 to move up and down along the rear support column of the support mounting base 1, thereby adjusting the height of the surface treatment device to reach the appropriate treatment position. The second motor 10 is started, and its output end drives the second threaded rod 14 to rotate. The moving base 15 is threadedly connected to the second threaded rod 14, and the conical blocks on both sides of the upper end of the moving base 15 slide in cooperation with the conical grooves on the lower surface of the sliding support plate 9, ensuring that the moving base 15 moves smoothly. In this way, the polishing disc 6 can move horizontally to the surface of the craft gift to be treated. Then, the third motor 16 is started, and its output end drives the mounting base 3 to rotate. The rotation of the polishing disc 6 causes the polishing disc 6 to rotate, polishing the surface of the craft gift. During the surface treatment, the fans 17 inside the upper part of the two dust collection boxes 8 are activated, generating suction to draw the dust generated during the process into the dust collection box 8. When the dust passes through the activated carbon adsorption plate 2 on the inner wall of the sliding block 5, it is adsorbed and filtered, and the purified air is discharged. The sliding block 5 is installed on the dust collection box 8 by bolts, making it easy to disassemble and replace the activated carbon adsorption plate 2. Then, when it is necessary to disassemble the polishing disc 6, the rotating threaded sleeve 4 is rotated. Because the rotating threaded sleeve 4 and the rotating threaded rod 2... 2. Threaded connection: When the threaded sleeve 4 is rotated, the threaded rod 22 will move inside the threaded sleeve 4. As the threaded rod 22 moves, the limiting block 19 connected to it will slide in the second limiting block groove 21 and gradually exit from the first limiting block groove 20 on both sides of the upper end of the polishing disc 6. When the limiting block 19 is completely exited from the first limiting block groove 20, the polishing disc 6 is no longer constrained by the limiting block 19 in the polishing disc mounting groove 18 on the lower surface of the mounting base 3. The polishing disc 6 can be directly pulled upward from the polishing disc mounting groove 18 to complete the disassembly.

[0036] When the threaded sleeve 4 is rotated through the limiting device, the rotating threaded rod 22 will move inside the rotating threaded sleeve 4, and the limiting block 19 connected to it will slide in the second limiting block groove 21. When the limiting block 19 is removed from the first limiting block groove 20, the polishing disc 6 is no longer constrained by the limiting block 19 in the polishing disc mounting groove 18 on the lower surface of the mounting base 3. The polishing disc 6 can be directly pulled upward from the polishing disc mounting groove 18 to complete the disassembly. This makes the disassembly of the polishing disc 6 simple and quick, avoiding the need for workers to use special tools to disassemble it, and effectively improving the maintenance and repair efficiency of the polishing disc 6.
