The invention relates to the technical field of automobile hub machining, in particular to a fixture for hub machining, which comprises a fixing plate, at least three clamping blocks which are annularly distributed at intervals are arranged on the fixing plate, the clamping blocks are slidably connected with the fixing plate, and the clamping blocks radially slide along a circle where the at least three clamping blocks are annularly distributed. And a rotating plate is connected between the at least three clamping blocks and the same lifting ring. The hub machining device has the advantages that the lifting ring can be synchronously driven by the lifting driving mechanism to stably move up and down, the multiple clamping blocks are driven by the rotating plate to synchronously move in a linkage mode so that a hub can be clamped at high precision, and displacement generated during hub machining is avoided; the contact surface is higher than the non-contact surface, so that the contact area is reduced, and the
