Fixed mandrel device for induction hardening of planetary gear carrier

The utility model belongs to the field of part quenching, and relates to a fixed mandrel device for induction quenching of a planetary gear carrier. Comprising a fixing sleeve, and the fixing sleeve is used for fixing the planetary gear carrier, so that the large-mass planetary gear carrier is stably fixed, induction quenching of the large-mass planetary gear carrier is guaranteed, and high-precision positioning is achieved. A plurality of flow guide holes are formed in the fixed sleeve, so that the stability and uniformity of induction quenching are ensured, and the quenching quality is ensured. And a lifting table is arranged at the end part of the fixed sleeve and is used for lifting a large-mass planetary gear carrier for induction quenching. And a positioning rod is arranged on the fixed sleeve and is used for positioning the whole device, so that the stability of the device in the working process is ensured, and the induction quenching quality of the planetary gear carrier is further ensured. 本实用新型属于零件淬
