[0002] In order to achieve the ideal smoothness on the surface of the product, it is often polished with a polishing machine. A plane polishing machine is a type of polishing machine, which is suitable for plane polishing. It is different from round tube polishing, concave and convex surface polishing, etc. For workpieces that can be plane polished, it can remove scratches, spots, and collapsed edges on the surface of the workpiece, making the surface of the workpiece bright and smooth, creating a mirror effect.

[0003] A height-adjustable polishing machine for metal processing disclosed in Chinese patent application publication specification CN220863613U includes a device body and a connecting component arranged on the device body, the connecting component includes an adjusting part arranged on the top of the device body, the adjusting part is connected to a disassembly part, a limiting part is arranged on the upper end of the device body, a driving shaft fixedly connected to the output end of the polishing motor rotates, a connecting plate is fixedly connected to the end of the driving shaft, a polishing sheet is fixedly connected to the bottom of a limiting rod slidably connected to the inner wall of a limiting hole opened in the connecting plate, a rectangular block is sleeved on the outer wall of a fixing rod fixedly connected to the top of the connecting plate, and the rotating block is rotated to rotate the fixedly connected threaded rod, so that the threaded rod is threadedly connected to the inner wall of the threaded hole opened in the top of the limiting rod, and the polishing sheet fixedly connected to the bottom of the limiting rod is limited and fixed, and the connection structure makes it easy to disassemble and maintain.

[0004] When polishing a workpiece, the workpiece needs to be fixed. The above patent clamps and fixes the workpiece by a clamping plate, but the height of the clamping plate cannot be adjusted. If the height of the edge of the workpiece is lower than the height of the clamping plate, the clamping plate will hinder the movement of the polishing machine, making it difficult for the polishing machine to polish the edge of the workpiece. If the height of the clamping plate is too much lower than the workpiece, the clamping of the workpiece will become unstable. In addition, the polishing mechanism of the device cannot move on the surface of the workpiece and can only polish the surface of the workpiece located below. The staff needs to adjust the polishing position of the workpiece, which is cumbersome, time-consuming and labor-intensive. Utility Model Content
