Description

Technical Field

[0001] The present application relates to the technical field of wheel processing, and in particular to a wheel lathe. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Lathes are the most important type of metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. The function of a lathe is to perform cutting processing on rotating surfaces of various sizes and shapes, as well as spiral surfaces.

[0003] When a lathe processes a wheelset for a railway vehicle, the three-jaw chucks at both ends of the lathe clamp the wheelset, and then the wheelset is turned by a turning tool. However, most lathes can only process one type of wheelset and cannot process wheelsets of different types, which has great limitations in wheelset processing. Utility Model Content
