最近我厂加工一批带锥度的工件,锥度为14.4:1,工件外径为360米,按往常的加工方法,这样大的锥度要将小刀架扳动约82°,这在一般的车床上或用一般加工方法是比较困难的。由于进刀要靠手动,劳动强度大,生产效率低,质量不能保证。因此,我们制做了如图所示的靠模装置,在车床中拖板上安装一个滚轮,在尾架导轨上固定一块底板,底板上紧固好靠模 Recently, I plant a number of processing with a taper of the workpiece, the taper of 14.4: 1, the workpiece diameter of 360 meters, according to the usual processing methods, such a large taper to move the knife holder about 82 °, which in a general lathe Or use the general processing method is more difficult. Because of the manual to feed, labor-intensive, low productivity, quality can not be guaranteed. Therefore, we made a model as shown in the figure device, in the lathe to install a roller on the carriage, the tail rail fixed to a base plate, the base plate to fasten the master model
