我厂是一个新广,使用的大都是通用设备,劳动强度大,效率低。我们根据现有五台Z32K摇臂钻加工品种多和升降频繁的情况进行了改装,使手摇升降变为自动升降(图见下页),效果良好。自动升降动力来源于Z32K变速箱里的滑动变速大齿轮,由它将动力传递给自动升降传动箱的大齿轮23,经过伞齿轮15传递给轴13,这样便通过皮 I plant is a new wide, most commonly used equipment, labor-intensive, low efficiency. According to the existing five sets of Z32K rocker drilling variety and frequent lifting conditions were modified, the hand lift into automatic lift (see the next page), the effect is good. Automatic lifting power comes from the Z32K gearbox sliding gear, which will be the power transmitted to the automatic lifting gear box 23, the bevel gear 15 is passed to the shaft 13, so that through the skin
