鼓形齿轮是矿冶设备中传动零件之一(见图1)。以前,在Y320滚齿机上加工m12的鼓形齿轮,需要八小时左右,由于采用手摇横向进刀,所以劳动强度大,而且精度差、易出废品。现在,我们将横向手动进给改为机械——电气复合靠模装置的自动进给,从而减轻了劳动强度、缩短了加工工时、提高了产品质量,加工光洁度达▽5,保证了设计要求。 Drum gear mining equipment is one of the transmission parts (see Figure 1). In the past, the Y320 hobbing machine m12 drum gear processing takes eight hours or so, due to the manual horizontal infeed, so labor-intensive, and poor precision, easy to waste. Now, we have changed the horizontal manual feed into the automatic feed of the mechanical-electric composite die-setting device, which has reduced the labor intensity, reduced the working time and improved the product quality. The machining finish reaches ▽ 5, which ensures the design requirements.
