[0002] The rear axle bearing sleeve of a vehicle is an important part of the rear axle system of the vehicle. It mainly supports the wheels and connects the rear wheels. At the same time, it also undertakes the functions of driving, deceleration and differential in the drive axle. The rear axle bearing sleeve is usually composed of two half-axles, which can realize the differential movement of the half-axles.

[0003] When processing existing rear axle bearings, most of them adopt horizontal lathes to mill the end faces of the bearings, which requires workers to manually load, clamp, and unload materials. Although this processing method can realize the milling of the end faces of the bearings, it has the following shortcomings: 1. Manual loading, unloading, and clamping have low work efficiency, and debris will fly during the milling process of the machine tool. The temperature of the bearing sleeve after milling is high, which may easily cause injuries to workers and pose safety problems. 2.

[0067] The first motor 23 is controlled to rotate 90 degrees. During the rotation process, the second driven gear 296 in the clamping mechanism 29 contacts the unloading plate 213 on the T-shaped frame 25. Driven by the unloading plate 213, the clamping mechanism 29 releases the limit of the grinding bearing sleeve 6. The center of gravity of the bearing sleeve 6 is located on the inclined surface of the lower clamping plate 293. The bearing sleeve 6 tilts under the action of its own gravity and falls on the unloading plate 5, completing the unloading operation.

[0068] Under the control of the PLC control center, the above steps are cycled to realize the automatic loading, milling, grinding and unloading operations of the bearing sleeve 6, thereby realizing automated production and processing.
