[0002] In the process of machining high-precision gear ring brackets, heat treatment and press quenching operations are often required.

[0003] A high-precision gear ring bracket press quenching fixture currently in use mostly directly stamps the gear ring bracket in the press quenching fixture. The stress generated by this stamping method is too large. Therefore, during press quenching, the gear ring bracket is easily deformed due to stress concentration, thereby reducing the processing quality of the gear ring bracket by the press quenching fixture, which is not conducive to subsequent use. At the same time, the bottom of the press quenching fixture is mostly in direct contact with the ground. This contact method does not have mobility. Therefore, when transporting, it is necessary to use a transport tool to achieve its movement, thereby reducing the flexibility of the press quenching fixture.
