背景技术Background technique
车床是主要用车刀对旋转的工件进行车削加工的机床。在车床上还可用钻头、扩孔钻、铰刀、丝锥、板牙和滚花工具等进行相应的加工。按用途和结构的不同，车床主要分为卧式车床和落地车床、立式车床、转塔车床、单轴自动车床、多轴自动和半自动车床、仿形车床及多刀车床和各种专门化车床，如凸轮轴车床、曲轴车床、车轮车床、铲齿车床。在所有车床中，以卧式车床应用最为广泛。A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used for corresponding processing on the lathe. According to different purposes and structures, lathes are mainly divided into horizontal lathes and floor lathes, vertical lathes, turret lathes, single-spindle automatic lathes, multi-spindle automatic and semi-automatic lathes, profiling lathes and multi-tool lathes and various specializations. Lathes, such as camshaft lathes, crankshaft lathes, wheel lathes, spade tooth lathes. Among all lathes, horizontal lathes are the most widely used.
现有的车床在加工轴类工件时，通常是将轴类工件用卡盘进行夹紧固定，由于现有的卡盘采用传统结构，无法对轴类工件伸出卡盘的轴向长度进行自由精确的调整，导致轴类工件在加工过程中震动大，加工精度低，材料损耗大，影响轴类工件的加工质量，不利于企业的生产和发展。When the existing lathes process the shaft workpiece, the shaft workpiece is usually clamped and fixed by the chuck. Since the existing chuck adopts the traditional structure, it is impossible to freely adjust the axial length of the shaft workpiece protruding from the chuck. Accurate adjustments lead to large vibrations of shaft workpieces during processing, low machining accuracy, and large material loss, which affects the processing quality of shaft workpieces and is not conducive to the production and development of enterprises.
