从一个加工位置移动重型工件到另一个加工位置的通用气动系统,一般需用外部的阀来控制零件的加速及减速,而且在行程的终点往往需要缓冲器。最近美刊介绍了一种新型回转分度器,它由部件内部的机械连杆机构来控制回转运动的速度,其特点是不管 General pneumatic systems that move heavy workpieces from one machining location to another generally require an external valve to control acceleration and deceleration of the part and a buffer is often required at the end of the stroke. Recently, the American Journal introduced a new type of rotary indexer, which consists of a mechanical link mechanism inside the part to control the speed of slewing motion, which is characterized by no matter
