摘　　要：由于细长轴类零件刚性较差,同时机床主轴卡盘转动的作用使工件产生振动,为了保证工件加工精度,采用一种可移动主轴箱的夹紧系统,通过主轴箱夹紧系统垂直方向四套夹紧油缸和水平方向两套夹紧油缸,实现了自动化控制的夹紧系统在机床上的应用,达到了主轴箱精准定位的效果。Because the slender shaft parts have poor rigidity,and at the same time,the spindle chuck rotation causes the vibration of workpiece,in order to ensure the machining accuracy of workpiece,a clamping system for movable headstock is used in this paper. Through four sets of clamping hydro-cylinders in vertical derection and two sets of clamping hydro-cylinders in horizontal direction,the application of automatic control for clamping system in machine tool is realized,and the effect of accurate positioning of the headstock is thus achieved.
