[0002] Polishing is a processing method that uses mechanical, chemical, or electrochemical processes to reduce the surface roughness of a workpiece in order to obtain a bright and smooth surface. It involves using polishing tools and abrasive particles or other polishing media to refine the surface of a workpiece.

[0003] While existing polishing disc structures have the ability to polish metal sheets, their polishing area and polishing effect are poor.

At the same time, it lacks the function of adjusting the polishing pressure between the wheel and the sheet to be processed, resulting in poor polishing effect.

[0004] Therefore, it is necessary to propose a polishing disc structure for metal sheets to solve the above-mentioned technical defects. Summary of the Invention

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0021] like Figures 1-4 As shown, this utility model embodiment specifically provides a polishing disc structure for metal sheets, including: The drive disk 1 is rotatably mounted on the fixed cylindrical base 2; the drive disk 1 is driven to rotate by an external drive motor. The pressure regulating component 3 is circumferentially arranged on the drive disk 1. The pressure regulating component 3 includes: a bearing 31, a keyway sleeve 32, a key shaft 33, and an elastic cylinder 34. The drive disk 1 is circumferentially fixedly connected to the bearing 31. The keyway sleeve 32 is rotatably installed inside the bearing 31. The key shaft 33 is slidably inserted inside the keyway sleeve 32. The upper end of the key shaft 33 is movably connected to the elastic cylinder 34. The elastic cylinder 34 is movably connected to the fixed cylinder seat 2. Through the setting of the bearing 31, the polishing disk 4 can rotate under the action of the meshing transmission of the large gear ring 5 and the small gear 6. Through the designed structure of the keyway sleeve 32 and the key shaft 33, when adjusting the pressure between the polishing disk 4 and the surface of the metal plate to be processed, the spring 342 in the elastic cylinder 34 of the pressure regulating component 3 can be vertically slidably pushed to achieve the function of adaptive pressure regulation. The polishing disc 4 is detachably locked to the lower end of the key shaft 33 for easy disassembly and replacement.

[0022] The top axial part of the drive disk 1 also includes an integrally formed drive shaft 11. The drive shaft 11 extends to the top of the fixed cylinder 2 and is rotatably mounted with the fixed cylinder 2 through a bearing 31, so as to be connected to an external drive motor for driving.

[0023] The elastic cylinder 34 includes a cylinder body 341, a spring 342, and a slider 343. The bottom of the inner cavity of the cylinder body 341 is movably engaged with a limiting block 331 at the upper end of the key shaft 33. The spring 342 abuts against the limiting block 331 and the top of the inner cavity of the cylinder body 341. The slider 343 is installed on the side wall of the cylinder body 341 and is slidably connected to an annular groove 21 on the inner wall of the fixed cylinder seat 2. The polishing pressure can be adjusted by the spring 342. While the polishing disc 4 revolves following the drive disc 1, the elastic cylinder 34 revolves following the disc through the cooperation of the slider 343 and the annular groove 21 to avoid motion interference. At the same time, it can limit the vertical position of the elastic cylinder 34 to prevent axial movement, that is, it does not affect the pressure applied by the spring 342 to the polishing disc 4. Moreover, through the movable engagement of the limiting block 331, the rotation and vertical sliding of the key shaft 33 can be realized.

[0024] It also includes a large gear ring 5 and a small gear 6; the large gear ring 5 is arranged on the inner wall of the fixed cylinder seat 2, and the small gear 6 is sleeved on the key shaft 33 between the elastic cylinder 34 and the keyway sleeve 32. The small gear 6 and the large gear ring 5 mesh and drive each other to realize the rotation of the polishing disk 4 on the key shaft 33, while not affecting the function of the key shaft 33 in adjusting the pressure in the vertical displacement with the polishing disk 4.

[0025] The circumferential wall of the drive disk 1 also includes an integrally formed annular guide rail 12, which is slidably connected to the annular groove 22 on the inner wall of the fixed cylinder seat 2, ensuring the stability of rotation.

[0026] The top of the fixed cylinder base 2 also includes several circumferentially opened fixing holes 23, which facilitates the installation with external XYZ axis modules or robotic arms to drive the polishing disc structure to move and polish.

[0027] The pressure regulating components are arranged in three circumferential directions, with at least four components, which increases the polishing area.

[0028] The polishing disc 4 is made of high-hardness alloy, which enhances the polishing durability and lifespan.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
