Fixing device for machining axle housing of automobile drive axle

The invention discloses a fixing device for automobile drive axle housing machining and relates to the technical field of automobiles, the fixing device comprises a bottom plate, and a fixing clamping mechanism is arranged at the top of the bottom plate. Cylindrical parts at the two ends of the drive axle housing are placed in the two arc-shaped sleeves on the bottom plate, and the inner walls of the arc-shaped sleeves are inclined planes, so that when the cylindrical parts at the two ends of the drive axle housing are placed in the two arc-shaped sleeves, transverse component force can be applied to the cylindrical parts at the two ends of the drive axle housing along with gravity; when the drive axle housing is placed in the arc-shaped sleeve, the drive axle housing can automatically slide to a heavy stress balance state, so that the drive axle housing is stably placed, and the problems of abrasion and deformation caused by non-uniform stress on the surface of the drive axle housing are reduced. 本发明公开了一种汽车驱
