摘要
数控车床进给系统是指能分别沿着X 向和Y向做进给运动的系统,是许多机电一体化设备的基本部件,如数控车床的纵—横向进刀机构、数控铣床和数控钻床的X-Y工作台、激光加工设备的工作台、电子元件表面贴装设备等。模块化的X-Y数控工作台,通常由导轨座、移动滑块、工作、滚珠丝杠螺母副,以及伺服电动机等部件构成。其中伺服电动机做执行元件用来驱动滚珠丝杠,滚珠丝杠螺母带动滑块和工作平台在导轨上运动,完成工作台在X、Y方向的直线移动。导轨副、滚珠丝杠螺母副和伺服电动机等均以标准化,由专门厂家生产,设计时只需根据工作载荷选取即可。控制系统根据需要,可以选取用标准的工作控制计算机,也可以设计专用的微机控制系统。
