[0003] A patent application with publication number CN117943568A discloses a crankshaft machining and turning machine tool, which includes a machine tool machining table. The machine tool machining table side is fixedly installed with a rotary drive main machine. This application can clamp the crankshaft raw material between another eccentric shaft adjusting clamp group by moving one of the eccentric shaft adjusting clamp groups.
