看了《机械制造》上刊登的关于C618车床扩大加工范围的途径方面的几篇文章,对我们启发很大。针对加工蜗杆螺纹时,计算比较复杂、不够简便的情况。我们作了简单易行的改进。经生产实践证明效果较好,现介绍如下: 原C618车床有11只挂轮,现增加一个齿数z=110的挂轮,就可以简化计算过程,而不必对原有结构或部件进行改造。 [例]在C618车床上车削模数2mm的双头蜗杆,试计算挂轮和变换手柄位置。 [解]在走刀箱铭牌上选取螺距4mm的位置,其挂
Read the article published in the “Machinery” published on the C618 lathe to expand the scope of the processing of several articles, inspired us a lot. For the processing of worm threads, the calculation is more complicated, not easy enough situation. We made simple and easy improvements. The production proved to be better, are presented below: The original C618 lathe with 11 hanging wheels, now adding a number of teeth z = 110 hanging wheel, you can simplify the calculation process, without having to rebuild the original structure or components. [Example] In the C618 lathe turning module 2mm double-headed worm, try to calculate the location of the hanging wheel and change the handle. [Solutions] on the nameplate on the knife box select the pitch 4mm position, the hanging
