[0002] Heat treatment is a comprehensive process that controls the performance of materials by heating, keeping them warm, and cooling them in a certain medium, and by changing the surface or internal structure of the materials. High-frequency heat treatment uses high-frequency induction heating (IH) based on electromagnetic induction to harden the surface of metal parts by rapidly (in seconds) heating them to high temperatures and then rapidly cooling them. Since it can improve the wear resistance, fatigue strength, and toughness of metal parts, it is widely used in the fields of automobiles, construction and civil engineering machinery, and machine tool parts.

Although the metal object can be positioned to a certain extent, when processing shaft materials, the material needs to be placed in the center to improve the uniformity of heating. The fixing method of the prior art is cumbersome to operate and is not convenient for centering the material. Utility Model Content
