下面介绍一组齿轮加工夹具结构。这些结构大都具有定心精度高、生产效率高、操作简便等优点,使用效果良好。一、车齿坯夹具 1.车齿坯用斜楔式滑块定心夹紧心轴图1所示系斜楔式滑块定心夹紧心轴。心轴对于加工工件所具有定心与夹紧作用,它是通过滑块与锥体拉杆右端的圆锥工作表面之间的相对滑动来实现的。当装在机床主轴尾端的气缸(或油缸)活塞拉杆带动心轴上的锥体拉杆向左移动时,滑块向外移升,
Here is a set of gear processing fixture structure. Most of these structures have the advantages of high centering accuracy, high production efficiency, easy operation and the like, and the use effect is good. First, the car billet fixture 1. Car billet with wedge-type slider centering clamping mandrel Figure 1 shows the wedge-type slider centering clamping mandrel. The mandrel has a centering and clamping action on the workpiece, which is achieved by the relative sliding between the slider and the conical working surface at the right end of the cone rod. When installed in the end of the machine spindle cylinder (or cylinder) piston rod to drive the mandrel cone lever moves to the left, the slider moves up,
