Abstract

The invention relates to a fixture for turning a wheel hub, which includes a main shaft and a centering assembly; the centering assembly includes a collet that can extend into the center hole of the wheel hub, the collet is connected to one end of the main shaft and is connected to the main shaft through transmission, and the collet It can expand outward to clamp the inner wall of the center hole of the hub to transmit the torque generated by the main shaft to the hub. The clamp provided by the present invention extends into the central hole of the hub through the collet, and the collet can radially position the hub, and the collet is connected to the main shaft through transmission, and the collet expands outward to clamp the inner wall of the center hole of the hub. , so that the collet can also transmit the torque generated by the spindle to the hub. It can be seen that the collet also plays the role of radially positioning the hub and transmitting the torque of the main shaft, which simplifies the structure and is beneficial to reduce the cost of manufacturing.

Description

technical field [0001] The invention relates to the technical field of automobile wheel hub processing, in particular to a fixture for wheel hub turning. Background technique [0002] The hub is the metal part that is mounted on the axle in the center that supports the tire. In order to meet the precision requirements of the product, it is usually necessary to turn the semi-finished wheel hub, that is, the inner and outer surfaces of the wheel hub need to be turned separately. In the related art, a jig is usually used to clamp the wheel hub. The jig includes a main shaft and drives the wheel hub to rotate through the rotating shaft, so that the inner surface and the outer surface of the wheel hub can be cut with a tool. However, in the related art, the clamp generally includes a part that transmits the torque of the main shaft and a part that extends into the center hole of the hub to position the hub in the radial direction, and the two parts are arranged separately, and t...
