PURPOSE: A clamper for a high frequency heat treatment apparatus for a large bearing is prevent damage to the surface of a large bearing during clamping by employing a variable diameter assembly and a motion change assembly. CONSTITUTION: A clamper for a high frequency heat treatment apparatus for a large bearing comprises a variable diameter assembly and a motion change assembly. An end of the variable diameter assembly is hinge-coupled to the lower center of a frame(100), and a contact roller contacts the exterior surface of the large bearing as the other end of the variable diameter assembly is lifted. The motion change assembly reciprocates in the direction parallel to the surface on both lower sides of the variable diameter assembly, thereby lifting the other end of the variable diameter assembly. |
