为解决解放(CA 10 B)倒车双联齿轮的内孔磨削质量,我们制造了图示节圆夹具,达到齿轮节圆偏差0.02～0.04毫米,保证了图纸要求0.06毫米。夹具优点:1.由于夹具体在靠近卡盘的一端开出四个圆心角60°的天窗口,实现了零件的“另端”夹紧,从 In order to solve the internal hole grinding quality of Jiefang (CA 10 B) reversing double gear, we manufactured a graphing jig with a pitch circle deviation of 0.02 to 0.04 mm, which ensured that the drawing required 0.06 mm. Fixture advantages: 1. As the clamp body near the end of the chuck out of four central angle of 60 ° skylight, to achieve the parts of the “other end” clamping, from
