液压机床上的夹紧油缸都是随主轴一道旋转的。当主轴转速较高时,就会产生不均衡的离心力,影响到机床主轴精度。为解决这一问题,可用固定式油缸取代旋转式油缸。一、固定式油缸结构及工作原理油缸前盖12和油缸后盖5均用六根内六方螺栓6固定在油缸8上。活塞10内装有一套双向推力球轴承1。活塞前后装有前盖16和后盖4分别用四根外六方螺栓固定。各密封部位均用O型密封圈密封。整套油缸通过过渡接盘
Hydraulic cylinder clamping cylinder are with the spindle rotation. When the spindle speed is high, it will produce unbalanced centrifugal force, affecting the accuracy of the spindle. To solve this problem, the fixed cylinder can replace the rotary cylinder. First, the fixed cylinder structure and working principle Cylinder front cover 12 and fuel tank back cover 5 are six six bolts 6 fixed on the cylinder 8. Piston 10 is equipped with a set of two-way thrust ball bearings 1. The front and rear pistons are equipped with a front cover 16 and a back cover 4, respectively, with four outer hexagonal bolts. The sealing parts are sealed with O-ring. The entire cylinder through the transition dish
