摘 要
本文讨论了在现有的加工条件下完成对液压缸套内孔的加工,即深孔加工,提出了车床改造的方案。简单介绍了深孔的发展概况、深孔加工系统的组成、深孔加工系统中的常用装置、深孔加工中的常见问题。至今,深孔加工机床甚少,普通车床不具有加工深孔的功能,因此,将普通车床C620-1改装为深孔加工机床,具有深远的意义。
关键词: 深孔加工; 车床改装; 进给机构; 钻削
Abstract
This article discussed in the existing processing conditions of hydraulic cylinder liner completed in the hole processing, namely the deep hole processing, puts forward the lathe reforming scheme. Briefly introduces the general situation of the deep hole, deep hole processing system composition, deep hole processing system of common device, deep hole processing of common problem. So far, the deep hole processing machine tool little, ordinary lathe don't have the function of the deep hole processing, therefore, the ordinary lathe C620-1 modified for the deep hole processing machine tools and has far-reaching significance.
Key words: the deep hole processing ; lathe transformation ; feed mechanism ; drilling
