我校实习工厂中常遇到抽油机机轴两端的螺纹孔的加工,工艺过程是在车床上先打孔再攻螺纹。 为了能在车床上进行钻孔,开始采用钻头装在尾座套筒内,用固定尾座,手动进给工。由于来回推拉尾座,又靠手动进给,因此劳动强度大,生产率低。 现我们设计了如图所示的装置。钻头装在专门设计的尾座套筒内,套筒装在去掉丝杠的尾座内。加工时,大拖板挂自动,通过固定在刀架上的拨叉带动套筒
I often encountered in the factory internship factory pumping shaft ends of the threaded hole processing, the process is in the lathe first punch and then tapping thread. In order to be able to drill holes in the lathe, began to use the drill installed in the tailstock sleeve, with a fixed tailstock, manual feed workers. Due to push back and forth tailstock, but also by manual feeding, so labor-intensive, low productivity. Now we have designed the device as shown. The drill bit is housed in a specially designed tailstock sleeve that is housed in the tailstock with the lead screw removed. When processing, the big carriage hangs automatically, and the sleeve is driven by the fork fixed on the knife holder
