Abstract

The invention provides a high-frequency quenching device for a right-angle part of a rotary body. The device comprises an induction coil, a magnetizer, a tray, a stop screw and a connecting column, wherein the tray is used for supporting a rotary body part to be processed, the connecting column is connected with the tray and an external machine tool, and the stop screw is used for fixing the tray and the connecting column; the induction coil is mounted on the external machine tool, can be connected to a high-frequency current and is coaxial with the rotary body part to be processed; the section, close to the right-angle root part of the rotary body part to be processed, of the induction coil is sharp-angle-shaped; the magnetizer is bonded with and wraps the induction coil, and only is the sharp-angle-shaped part of the induction coil exposed out of the magnetizer. According to the device, the circular coil effect of electromagnetic induction can be properly reduced, overhigh heating speed of a vertical cylindrical surface is avoided, the sharp angle effect during the electromagnetic induction can be effectively avoided, and the effect of heating the root part of the part is achieved by virtue of drive current of the magnetizer.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a high-frequency quenching device for a right-angle part of a revolving body, which can meet the requirement of simultaneous heating of two vertical surfaces and roots of the right-angle part of a revolving body, and has stable processing quality. Background technique [0002] In the design process of some optoelectronic mechanical systems, in order to meet the overall requirements such as the technical indicators of the overall system, a turntable with a non-standard guide rail structure is often designed. The hollow shaft key parts used in these non-standard guide rail structure designs all have high-frequency quenching technical requirements for rotary right-angle guide rails, requiring both vertical surfaces and roots to reach high hardness (HR58~63), and the quenching surface of the guide rail is narrow. The root is a right angle structure, see Figure 6 . When using...
