This invention discloses an induction hardening device for machining bevel gear shaft workpieces, belonging to the technical field of heat treatment processing equipment. The device includes a housing with a partition inside. A multi-station turntable is located above the partition, and a frame is connected to the top of the turntable. Along the circumferential direction of the multi-station turntable, there are bevel gear preheating stations and overall heating stations. Each station has a corresponding lower center assembly, and an upper center assembly is located above each station. The upper center assemblies are mounted on the frame via an elastic floating mechanism and are coaxially engaged with the lower center assemblies. This invention achieves uniform hardening of bevel gear workpieces through a differentiated station layout and adapts to the thermal deformation of the workpiece through the elastic floating mechanism, effectively improving the coaxial arrangement and mutual cooperation in the direction. This invention achieves differentiated heat treatment of bevel gear workpieces, ensuring the consistency of the hardened layer depth and adapting to the thermal expansion and contraction deformation of the workpiece, thus avoiding workpiece damage.
