The application scenarios of the grinding device are very wide, covering multiple industries and fields. First of all, in the metal processing industry, the grinding device is indispensable. Whether it is steel, aluminum or other metal materials, burrs, unevenness and other problems may occur during the processing. At this time, it is necessary to use a grinding device for subsequent processing to improve the surface quality and precision of the workpiece. Secondly, in the furniture manufacturing industry, the grinding device also plays an important role. The surface quality of furniture directly affects its appearance and service life. Therefore, it is necessary to use a grinding device to polish the surface of the furniture to make it smoother and more delicate. In addition, in the automobile manufacturing, hardware products, mold manufacturing and other industries, grinding devices are also widely used.

[0003] The shortcomings of existing mechanical processing grinding devices:

[0004] First, the existing grinding device needs to constantly adjust the angle of the grinding disc during grinding, but the existing grinding disc angle needs to be constantly adjusted manually, and the grinding disc will collide with the grinding parts during the grinding process, making it difficult for the staff to control the angle of the grinding disc, which will consume a lot of time and manpower, resulting in low efficiency of the entire grinding process. This not only increases production costs, but may also cause delays in production progress.

[0005] Second, the existing grinding device needs to fix the object and push it to the surface of the grinding disc during grinding, but the existing objects are not easy to fix, which may cause movement or shaking during the grinding process, affecting the grinding effect. Utility Model Content
