Abstract: A milling fixture for forged wheel includes a connecting plate installed on a milling machine table, a linear bearing installed on the connecting plate, a small diameter end of a positioning rod penetrates through a spring and a linear bearing, and a limiting screw installed on a side wall of the linear bearing and connected with the positioning rod. Under the coaction of the spring and an external force, the positioning rod is configured to move in the linear bearing. Bidirectional threaded rods are uniformly installed on a bottom plate, one end of each of the bidirectional threaded rods penetrate through pressure claws, the pressure claws are sandwiched between compression nuts and the connecting plate. The fixture can meet the requirement for milling a forged wheel, and at the same time, has the characteristics of a simple structure, is convenient to manufacture, provides stable performance and is low cost.
