Problems solved by technology

[0002] In the process of milling the car crankshaft, the car crankshaft needs to be completely fixed, and the car crankshaft cannot be moved to ensure the quality and accuracy of the car crankshaft milling hole. Due to the structural characteristics of the car crankshaft, it is difficult to fix the car crankshaft. Moreover, in the process of milling holes on the crankshaft of the automobile at a position not on the center line, the crankshaft of the automobile is easy to move and rotate, resulting in a reduction in the quality and accuracy of the milled holes. The crankshaft itself causes damage, but the existing milling device for automobile crankshaft processing cannot solve the above problems, and the existing milling device for automobile crankshaft processing does not have the function of automatic alignment, and the processing efficiency can be further improved. For this reason, the present invention proposes a kind of milling device for automobile crankshaft machining
