Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing machines, in particular to a grinding and polishing machine which is convenient for automatic clamping. Background Art

[0002] A grinder and polisher is a mechanical device used for surface treatment of materials such as metal, wood, and stone. Traditional grinders and polishers require manual clamping of workpieces during operation, which is not only labor-intensive but also inefficient.

[0003] According to the patent document: CN115431120A, a solid wood furniture polishing and grinding machine is disclosed, which relates to the field of solid wood furniture polishing and grinding, and solves the problem that the existing solid wood furniture polishing and grinding machines are difficult to automatically identify the width of solid wood furniture raw materials and polish both sides evenly and simultaneously, thereby reducing the polishing efficiency. The machine comprises a machine body, a conveying mechanism, a clamping mechanism, a polishing mechanism and a linkage mechanism. A driving motor is fixedly connected to the machine body, and mounting frames are fixedly connected to both sides of the machine body. The solid wood furniture polishing and grinding machine is convenient for automatically conveying the solid wood furniture raw materials placed on the machine body while linking the clamping mechanisms on both sides to move toward the middle at the same time and push the raw materials to the center. After the clamping forces of the clamping mechanisms on both sides are the same, the linkage polishing mechanism is deflected to clamp both sides of the raw materials for polishing, thereby ensuring that the clamping force and polishing force on both sides of the raw materials during polishing are the same, preventing uneven polishing on both sides and improving the polishing and grinding efficiency.

[0004] After performing multiple grinding and polishing operations, the grinding and polishing disc of the grinder and polisher will need to be replaced due to wear or removed for maintenance. However, in existing grinders and polishers, replacing the grinding and polishing disc usually requires the operator to manually disassemble and install it, which is not only time-consuming but also prone to improper operation, affecting the service life and grinding and polishing effect of the grinding and polishing disc. In addition, since the disassembly and installation process of the grinding and polishing disc is relatively complicated, the operator needs to have certain technical knowledge and experience, which to a certain extent limits the popularization and application of grinders and polishers.

The rotating rod 7215 rotates to drive the gear 7216 to rotate and mesh with the second gears 7220 on both sides to rotate. The two second gears 7220 rotate to drive the first screw rod 7218 to rotate the transmission semicircular transmission plate 7234 and the push-pull plate 7233 to push the supporting chassis 7231 upward. When the rotating rod 7215 rotates the transmission semicircular transmission plate When the push-pull plate 7234 and the push-pull plate 7233 move upward to push the supporting chassis 7231, at the same time, the rotating rod 7215 rotates to drive the rotating disk 7248 to rotate at the same time, and the rotating disk 7248 rotates to drive the arc-shaped slide groove 7249 to rotate, so that the small slide bar 7247 slides on the inner wall of the arc-shaped slide groove 7249. Since the arc-shaped slide groove 7249 is an arc, when the rotating disk 7248 drives the arc-shaped slide groove 7249 to rotate to a certain angle, the small slide bar 7247 controls the limit plate 7245 to drive the slider 7244 on the slide bar 724 3 slides inwardly, so that the limiting block 7246 moves to release the limiting of the inner wall of the limiting circular groove 733 opened in the middle of the bottom of the grinding and polishing top plate 731, and while releasing the limiting of the inner wall of the limiting circular groove 733, the supporting bottom plate 7231 pushes the grinding and polishing top plate 731 upward to move away from the control mechanism 72 and the grinding and polishing bottom shell 71, so that the staff can easily remove the grinding and polishing plate body 73, and when a new grinding and polishing plate body 73 needs to be installed, it only needs to be installed to the supporting plate 723 through the circular connecting groove 732 opened at the bottom of the grinding and polishing plate body 73 2, at this time, the conical gear motor 7212 can be restarted to make the whole transmission system run in the reverse direction, the two semicircular transmission plates 7234 move downward and pull the supporting bottom plate 7231 and the supporting plate 7232 to move downward, so that the grinding and polishing disc body 73 moves downward, and at the same time, the turntable 7248 rotates to control the limit block 7246 to expand outward, so that when the grinding and polishing top plate 731 is pulled downward by the supporting plate 7232, the limit block 7246 re-enters the inner wall of the limit circular groove 733, thereby fixing the grinding and polishing disc body 73.
