Abstract

A circumferential positioning device of automobile hub having rotary positioning seat, transition seat, bearing, positioning pin, positioning cylinder, bearing, base frame, main rotating shaft with sliding spline, coupling assembly, link snap-gauge assembly, lead screw, connecting bolt, nut, servo motor, lower bracket of main rotating shaft, small bracket of belt servo motor, belt pulley servo motor, small belt pulley axle, small belt pulley, belt, large belt pulley. The device in the present invention two radial grooves passing through the center that are formed in the bottom surface of the flange of the hub, correspond to the spoke direction on the facade of the hub and are just matched with the two radial bosses passing through the center on the top face of the positioning seat to achieve a positioning purpose.

First claim

The invention claimed is:

1. A circumferential positioning device of an automobile hub comprising: rotary positioning seat, a transition seat, a first bearing, a positioning pin, a positioning cylinder, a second bearing a base frame, a main rotating shaft with a sliding spline, a coupling assembly, a link snap-gauge assembly, a lead screw, a connecting bolt, a nut, a servo motor, a lower bracket of the main rotating shaft, a small bracket of a belt servo motor, a belt pulley servo motor, a small belt pulley axle, a small belt pulley, a belt, a large belt pulley, and an upper bracket of the main rotating shaft, wherein the rotary positioning seat, transition seat and bearing are fixed on the base frame; the positioning pin is connected to the positioning cylinder, and the positioning cylinder is fixed on the base frame and the upper bracket of the main rotating shaft; the main rotating shaft with the sliding spline, the coupling assembly and the lead screw are fixed inside the base frame, and they are fixedly rotated with the upper bracket of the main rotating shaft and the lower bracket of the main rotating shaft; the belt pulley servo motor drives the small belt pulley axle to drive the small belt pulley to rotate, and the large belt pulley is connected with the small belt pulley through the belt; the main rotating shaft with the sliding spline is connected with the large belt pulley through internal and external splines; the large belt pulley rotates to drive the main rotating shaft with the sliding spline to rotate in the second bearing, the servo motor is connected with the lead screw, the lead screw is connected with the main rotating shaft with the sliding spline through the coupling assembly, the nut is fixed on the lower bracket of the main rotating shaft through the connecting bolt, and the lead screw is driven by the rotation of the servo motor to move up and down in the nut, so as to drive the main rotating shaft with the sliding spline to move up and down; the link snap-gauge assembly is located in the coupling assembly.
