Description

Technical Field

[0001] The utility model relates to the technical field of hub bearing processing, and particularly relates to a numerical control lathe for hub bearing processing. Background Technique

[0002] Hub bearings are essential components used in automobiles. Their main functions are to bear the weight and provide precise guidance for the rotation of the hub. They bear both axial loads and radial loads. Hub bearings are generally composed of two sets of tapered roller bearings or ball bearings combined. The installation, greasing, sealing, and clearance adjustment of the bearings are all carried out on the automobile production line. When the bearing sleeve is processed and formed, the outer surface of the hub bearing sleeve is relatively rough and needs to be polished to make the outer surface of the bearing sleeve smooth. Most of the existing polishing devices can only polish the outer surface of a single bearing sleeve independently. It is necessary to place a single bearing sleeve on the polishing device separately, and only a single bearing sleeve can be polished, resulting in a slow polishing speed of the bearing sleeve and being not conducive to the batch production of bearing sleeves. For this reason, a numerical control lathe for hub bearing processing is proposed. Content of the Utility Model
