Description

Technical Field

[0001] The utility model belongs to the technical field of motor shaft processing, and relates to a heat treatment device, in particular to a heat treatment device for motor shaft processing. Background Art

[0002] The shaft is an important part of the motor. As the link between the motor and the equipment for electromechanical energy conversion, it supports the rotating parts, transmits torque, and determines the relative position of the rotating parts to the stator. Therefore, the motor shaft must have reliable strength and rigidity to ensure the realization of the preset design functions. The motor shaft needs to be quenched by heat treatment equipment during processing, so that the strength of the motor shaft can be increased after quenching.

[0003] After searching, it is found that a heat treatment device for motor shaft processing is disclosed in Chinese patent documents [Application number: 202122209660.9; Publication number: CN 215628174 U]. This heat treatment device for motor shaft processing includes: a main body, and the main body can be installed with the device, a control panel is installed on the front of the main body, and the control panel can control the device, and a heating tube is connected to the front of the main body near the control panel. In the heat treatment device for motor shaft processing, the second fixed rod can squeeze the end of the motor shaft when it moves, and the other end of the motor shaft can squeeze the first fixed rod. After the motor shaft is fixed, the first motor and the first threaded rod can drive the motor shaft to move back and forth, so that the motor shaft can be uniformly quenched. When the thread of the clamping block slides, it can slide through the moving groove. When the clamping block slides to the side of the motor shaft, the clamping block can clamp and fix the motor shaft through the arc shape of the end. After the motor shaft is clamped and fixed, the motor shaft can be taken out through the first motor and the first threaded rod, so that the motor shaft can be automatically taken out after quenching.

[0004] Although the clamping block disclosed in the patent can be automatically removed after the motor shaft is quenched, and the motor shaft can be quenched evenly, the motor shaft cannot be cooled immediately after the heat treatment. Utility Model Content
