Automobile hub positioning structure

The utility model relates to the technical field of hub machining and positioning, in particular to an automobile hub positioning structure which comprises a hub and a positioning mechanism. A plurality of hub positioning protruding blocks arranged at intervals are arranged on the inner ring of the outer wall of the hub in the circumferential direction. The positioning mechanism comprises a positioning carrier plate and a centering positioning disc; the centering positioning disc is fixed in the middle of the positioning carrier plate; a positioning convex ring is arranged on the outer ring of the centering positioning disc; the outer end face of the positioning protruding ring abuts against the inner end face of each hub positioning protruding block for positioning. The hub centering positioning mechanism has the advantages that the positioning convex ring on the centering positioning disc is matched with the hub positioning convex block in an abutting mode, it can be guaranteed that the positioning mechanis
