Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, in particular to a lathe for processing high-speed railway couplings. Background Art

[0002] A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms so that they rotate together and transmit motion and torque. It is sometimes also used to connect the shaft with other parts such as gears and pulleys. It is often composed of two halves, which are connected by keys or tight fits, fastened to the two shaft ends, and then connected in some way. The coupling can compensate for the offset between the two shafts due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, including axial offset, radial offset, angular offset or combined offset, as well as mitigate impact and absorb vibration. The processing of high-speed rail couplings needs to be performed on a lathe.

[0003] In the prior art, a series of cutting and grinding operations need to be performed on the outer surface of the high-speed rail coupling during processing on a lathe. However, the traditional lathe will inevitably block the outside of the coupling during the clamping process of the coupling. Therefore, the clamping position needs to be continuously switched during the processing, which causes great trouble to the coupling processing. Utility Model Content
