APPARATUS FOR FINAL FINISHING A WHEEL HUB OF A KNUCKLE ASSEMBLY AND RELATED METHOD

摘要

A fixture for final finishing flange faces of a hub of a knuckle assembly includes a mounting surface, a drive arrangement and a clamping arrangement. The drive arrangement is operative for engaging and rotating the hub of the knuckle assembly relative to the remainder of the knuckle assembly. The drive arrangement includes a drive member extending along a drive axis. The drive member is rotatable about the drive axis. The clamping arrangement is carried by the mounting surface. The clamping arrangement radially surrounds the drive arrangement and is operative for clamping the fixture relative to the mounting surface. The clamping arrangement includes a housing, a piston assembly radially positioned between the housing and the drive member, and a clamping sleeve radially disposed between the piston assembly and the clamping sleeve. The piston is movable in a first direction generally parallel to the drive axis. The clamping sleeve and the piston are cooperatively configured to radially force an upper end of the piston assembly radially outward in a second direction in response to movement of the piston in the first direction for engaging a back bore of the knuckle assembly.
