Abstract
The invention provides an output shaft bore heat treatment device which comprises a high-frequency quenching machine, a water tank and a main pipeline. The high-frequency quenching machine is provided with an induction coil which is fixedly sleeved on a water outlet end of the main pipeline. A water inlet end of the main pipeline is connected with the water tank. Cold water which flows into the main pipeline during the cooling process can be used to cool the output shaft bore as well as the induction coil. The output shaft bore is prevented from being heated by waste heat of the induction coil. Cooling velocity is faster, and cooling is more uniform. Branch pipelines are arranged at two sides of the main pipeline. Water inlet ends of the branch pipelines are connected with the water tank. The branch pipelines are used for cooling the outside surface of the output shaft. The main pipeline and the branch pipelines are provided with switch valves which have a function of adjusting pressure, flow and velocity of running water and are used to respectively adjust running water parameters of the main pipeline and the branch pipelines. Water sprayed out from the water outlet end due to large water pressure can be prevented from damaging a motor and other electrical equipment.
