Description

Technical Field

[0001] This utility model belongs to the field of heat treatment processing technology, specifically a stacking fixture for flange shafts. Background Technology

[0002] Automotive HV flange shafts are flange shafts used in automotive hybrid power systems. They play a crucial role in power transmission and structural connections in hybrid vehicles. Automotive HV flange shafts typically integrate multiple functional structures, including both the shaft body (used by ordinary shaft parts for torque transmission) and the flange structure. Bolt holes are generally evenly distributed on the flange for convenient and reliable connection to other components.

[0003] During the production and processing of automotive HV flange shafts, carburizing equipment is required to carburize the flange shafts. However, when the HV flange shafts are placed on a bracket for carburizing, their shape makes them difficult to stand upright and they are prone to tipping over. This can lead to uneven carburizing during subsequent heat treatment, thereby reducing product quality. Utility Model Content
