The present application provides a lathe fixture for clamping an automobile hub, including a first base, a deflection block support block, a deflection block, a deflection block guide shaft, a circular plate and the like, a second base is connected with the first base via a group of eighth screws and a second pin, the circular plate is connected with the first base via a group of sixth screws, a power chuck is connected to the second base via a group of third screws, and an O-shaped rubber ring is placed between a power chuck and a groove of the second base. Compared with the conventional automobile hub lathe fixture, the lathe fixture has a large relaxing/clamping travel and may adapt to the machining of hubs of multiple sizes.

A method for machining a wheel hub assembly for a vehicle includes providing a radially outer ring having a first radial flange, a radially inner hub having a second radial flange facing the first flange, and a plurality of rolling elements disposed between and rotatably coupling the outer ring and the hub. The hub is rotated simultaneously and asynchronously about the outer ring while machining a front surface of the second flange, which faces away from the first flange, and while rotating the outer ring about an axis of rotation of the wheel hub assembly, so as to form a machined surface of the second flange. The machined surface of the second flange is perpendicular to the axis of rotation and parallel to a front face of the first flange opposite to the front face of the second flange.
