摘　　要：文中采用静压导轨和直驱技术相结合的方式,设计了一种用于铣车复合加工中心的静压直驱转台。通过力矩电机直接驱动,可以有效地消除传统驱动方式下由中间传动环节引起的多种误差,提高转台的精度,改善动态响应特性。同时转台配有检测、冷却、锁紧机构,保证直驱转台可以完成铣削转台和车削主轴的功能转换,为铣车复合加工中心的发展提供技术支撑。A hydrostatic direct drive rotary table of the milling- turning compound CNC is designed by combination of static pressure guide and direct drive technology. Through driving by the torque motor,a variety of error caused by the intermediate transmission link in the traditional transmission mode can be eliminated effectively. The accuracy and the dynamic response characteristics of the rotary table are improved. The rotary table is equipped with detection,cooling,locking mechanism,and can ensure the rotary table function conversion of milling table and turning spindle. and the technical can provide support for the development of milling- turning compound CNC.
