[0002] Mechanical workpieces, also known as mechanical parts, are the basic components of machinery and are inseparable individual parts that make up machinery and machines. Workpieces refer to the objects to be processed during mechanical processing. They can be a single part or a combination of several parts fixed together. There are various types of workpiece processing methods, including turning, milling, planing, grinding, casting, forging, etc. The processing procedures of workpieces also change with the changes in processing methods. During the production and processing of mechanical workpieces, the surface of the mechanical workpieces needs to be polished to reduce the surface roughness of the mechanical workpieces in order to obtain a bright and smooth surface effect.

[0003] In a Chinese patent, a mechanical grinding and polishing device is disclosed, and its patent number is CN216608477U. In the patent, a mechanical grinding and polishing device includes a frame, a clamping table is installed at the inner bottom of the frame, and a sliding groove is provided at the upper end of the clamping table. Two moving blocks are slidably connected in the sliding groove, and the opposite ends of the two moving blocks are provided with a receiving groove, and the clamping block is slidably connected in the receiving groove. A plurality of springs are fixedly connected between the clamping block and the receiving groove, and the side wall of the frame is rotatably connected with a rotating rod, and the rotating rod passes through the two moving blocks and is connected with them. The outer wall of the frame is installed with a motor, and a transmission rod is installed at the output end of the motor. The transmission rod passes through the frame and is rotatably connected with it, and the other end of the transmission rod is rotatably connected with the inner wall of the frame. A mechanical grinding and polishing device can not only clamp the workpiece through the motor, but also can be applicable to various types of workpieces. At the same time, it can also realize the left and right movement of the grinder, so that the workpiece can be effectively polished.

[0004] The above-mentioned published patents have the following disadvantages:

[0005] (1) In the prior art, after a grinding and polishing device has been used for a period of time, the grinding and polishing head will become smooth due to repeated grinding, which will greatly reduce the effect of subsequent mechanical workpiece grinding operations and affect the normal use of subsequent mechanical workpieces.

[0006] (2) In the prior art, the grinding and polishing head needs to rotate at high speed. During the rotation process, the grinding and polishing head will move with the mechanical workpiece due to the mutual contact between the grinding and polishing head and the mechanical workpiece, resulting in a decrease in the working efficiency of the device in performing grinding and polishing operations on the mechanical workpiece.

[0007] (3) In the prior art, debris and dust of the mechanical workpiece are generated during the grinding and polishing process, and some fine dust will remain on the surface of the mechanical workpiece due to static electricity, affecting the subsequent operations of grinding and polishing. Harder dust particles will also cause wear on the surface of the mechanical workpiece. Utility Model Content
