[0002] The manufacturing process of general-purpose machine crankshafts involves grinding the crankshaft surface, primarily focusing on precision grinding of the main journals and connecting rod journals. Grinding the rotating surfaces of general-purpose machine crankshafts involves grinding the connecting rod diameter surfaces. Grinding the connecting rod diameters improves the surface finish, roundness, and fatigue life of the crankshaft. Existing grinding equipment for the rotating surfaces of general-purpose machine crankshafts typically employs CNC grinding, online monitoring, and adaptive compensation technologies to achieve high-precision, automated machining of the crankshaft's rotating surfaces.

[0003] The invention disclosed in CN101837559A proposes a crankshaft grinding method, comprising: the crankshaft rotating around its center of rotation, and the center of rotation of a grinding wheel moving along a preset motion trajectory curve, such that the high point of the grinding wheel always grinds the high point of the connecting rod journal. However, conventional grinding devices for crankshaft rotating surfaces are usually performed on a machining table. Besides the grinding wheel device for crankshaft grinding, they also include a clamping structure for clamping and carrying the crankshaft's rotation. In the specific implementation of crankshaft surface grinding, the grinding wheel will wear down over a long period of grinding. To ensure the grinding accuracy, it is necessary to regularly replace the worn grinding wheel. However, to ensure the convenience of crankshaft loading for users, the crankshaft clamping structure is usually located outside the machining table, while the crankshaft grinding wheel device is located in the middle of the machining table. The grinding wheel located in the middle of the machining table is blocked by the crankshaft and the crankshaft clamping structure, and the grinding wheel is connected to the grinding wheel drive device, which makes it inconvenient to replace the grinding wheel in the actual process. Therefore, this solution proposes a general-purpose crankshaft rotating surface grinding device and method to solve the above problems. Summary of the Invention
