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.

Abstract: A wheel fixture is disclosed. A main shaft drives a first positioning pull rod on a chuck body to extend and contract in the radial direction via a tightening screw, a clamping jaw is at a position within the travel range of extension and contraction, a wheel is positioned and clamped by the fixture, airtight support blocks are pressed down by the wheel and flush with the support plane of the clamping jaw, at this time, airtight ejector rods press second O rings to prevent air from flowing out of the airtight detection position, a detection system of a machine tool detects a preset air pressure value which indicate that the wheel has been placed correctly, and if the wheel is not placed correctly on the fixture, the machine tool will alarm through the detected pressure feedback.
