1、摘要在本次设计中，采用常规分离式主传动设计，机床主传动采用液压操纵机构，可实现十八级转速。机床主轴箱内的传动齿轮均经淬硬磨齿处理，传动比稳定，运转噪音低。机床采用单片式电磁刹车离合器，解决主轴的刹车及离合问题，离合器安装于主轴箱带轮处，使床头箱内结构大为简化，便于维修。进给方面，采用开环数控系统，即步进电机数控进给方式。采用步进电机开环数控系统已基本能满足进给精度的要求。主传动由于采用了分离传动发案，可较好的隔离电机及变速箱的震动，解决了热变形对主轴的影响，提高机床的加工精度。再者，数控系统采用单片机技术，可靠性高，成本低，经济性好。在总体
2、性能上可以达到经济精密数控机床之列，达到较好的性价比。该机床可以加工各种轴类、盘类零件，可以车削各种螺纹、圆弧、圆锥及回转体的内外曲面。作为通用型机床，特别适合汽车工业、摩托车行业、电子工业、航天、军工等行业，对旋转体类零件进行高效、大批量、高精度加工时采用。机床采用机、电、液一体化结构，整体布局紧凑合理，便于维修和保养，外形符合人机工程学的原理，宜人性好，便于操作。关键词：数控车床；CJ6132；分离传动；步进电机第49页共49页AbstractInthisdesign,theuseofconventionalseparationofth
