Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile axle parts assembly, in particular to a device for positioning and rotating automobile axle parts. BACKGROUND

[0002] In the process of assembling automobile axle parts, the axle housing needs to be rotated after assembling the main reducer, so as to facilitate the installation of other parts of the automobile axle. The existing rotation method is to use two overhead cranes, one of which uses a rope to hoist the shaft pipe at both ends of the axle housing, and the other hoists the main reducer.
