Beschreibung
Zusammenfassung:	The utility model discloses a crankshaft heat treatment system, which relates to the technical field of machining, and comprises a first heating cavity, a machine tool, a heat treatment auxiliary device, a straightening machine, a second heating cavity and a first grinding machine, the heat treatment auxiliary device is used for conducting carburizing treatment on the surface of the machined workpiece and conducting quenching treatment on the tempered workpiece, and the straightening machine is used for conducting straightening treatment on the workpiece subjected to carburizing treatment so as to eliminate deformation generated in the carburizing process. The second heating cavity is used for conducting tempering treatment on the straightened workpiece so as to eliminate deformation rebound generated after straightening treatment, and the first grinding machine is used for conducting grinding treatment on the surface of the quenched workpiece. Abrasion resistance and fatigue strength of the crankshaft can be
