我厂在开始制造F06型精密滚齿机的分度娲轮时,曾采用了图1所示的夹具。 夹具休是一个简单圆盘形零件,有由中心向圆周方向放射状的四条筋,在靠近工件(蜗轮)的滚齿部分又分布一周环伏筋。工件的定位面,一个是夹具体上的安装水平面;另一个是装于夹具体的垂直于安装水平面的心轴外 I plant in the manufacture of F06-type precision gear hobbing machine indexing round, had used the fixture shown in Figure 1. Fixture Hugh is a simple disc-shaped parts, from the center radial to the circumferential direction of the four ribs, in the workpiece near the hobbing part of the distribution of a week around the ring bar. The positioning surface of the workpiece, one is the mounting level of the clamp body; the other is the spindle mounted perpendicular to the installation level
