[0002] The production process of mechanical products is the whole process of transforming raw materials into finished products. The production process in a machinery manufacturing plant includes the transportation and storage of raw materials, technical preparation and production preparation of products, manufacturing of blanks, machining and heat treatment of parts, assembly, debugging, inspection of products, as well as sales and after-sales services of products. In the production process, the process of directly changing the shape, size, relative position and properties of the production object to make it a finished product or semi-finished product is called a process. The machining process refers to the whole process of using machining methods to change the shape, size, relative position and properties of the blank to make it a part.

[0003] The function of the mechanical processing edge grinding device is to effectively implement the edge grinding process in the processing operation of mechanical parts, effectively ensure the smoothness of the parts processing, do not hurt people, and achieve high-quality quality assurance. However, the current mechanical processing edge grinding device can only grind the upper and lower surfaces. It cannot grind the sides, especially the small edges. It is easy to scratch during the transportation process or cause the mechanical processing quality to be unsatisfactory. Manual grinding has to be used, which reduces the operating efficiency of the mechanical processing and the quality of the mechanical processing operation is very rough.

[0004] The existing patent (publication number: CN209970379U) discloses a small handheld T-shaped structure edge grinding sanding belt machine, which belongs to the field of small tool-type mechanical equipment. The sanding belt machine includes a handle, a main connecting frame, a secondary connecting frame, a sanding belt bracket, a driving synchronous wheel, a driven synchronous wheel, and a synchronous belt. The motor output shaft is connected to the driving synchronous wheel; the secondary connecting frame is connected to the main connecting frame, and the driven synchronous wheel is connected to the sanding belt driving wheel through a transmission shaft. The sanding belt driving wheel and the driven synchronous wheel are coaxial and concentric and fixed on the sanding belt frame by a bearing seat; a U-shaped tensioner and a lifting ring adjusting screw are provided on one side of the sanding belt driven wheel of the sanding belt machine. The device can adjust the left and right position of the sanding belt driven wheel in the length direction of the sanding belt frame through the U-shaped tensioner and the lifting ring screw, so as to achieve the purpose of adjusting the tension of the sanding belt or replacing the sanding belt; the sanding belt and the handle are set in a T-shaped layout, so that the sanding belt is evenly stressed and not easy to wear off. The main and secondary connecting frames are connected by adjustable screws, which is convenient for adjusting the position of the main and driven synchronous wheels. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The prior design cannot accurately locate the angle of the chamfer and the size of the edge grinding, which is not conducive to grinding and chamfering different original parts; 2. The prior design cannot detect the errors generated in the edge grinding process in real time, and cannot ensure the quality of the edge grinding. Utility Model Content
