摘 要数控加工的加工精度高,生产率高,能减轻操作者劳动强度,改善劳动条件,有利于生产管理的现代化以及经济效益的提高。它的进展和运用,影响着制造业水平高低,实现生产过程的数控化,已经成为当今制造业的进展方向,所以非常值得我们去讨论。本设计通过对数控车床六工位自动控制刀架工作原理的分析,综合考虑刀架工作过程的优缺点,确定了设计方案,得到了最终设计的结果,也达到了预先设定的目的。本设计主要包括了数控车床刀架机构的主要部件,其中包括转位机构,刀架的定位机构,驱动伺服电机的选择,蜗轮蜗杆的设计,刀架主轴的结构设计等。最终得到常用的数控车床六工位刀架应满足的要求。关键词:六工位;电动刀架 ABSTRACTWith its high working accuracy and productivity, the numerical control processing can reduce the operators’ labor intensity, improve labor condition, and is thus advantageous in the modernization of manufacturing management as well as improvement of economic benefit. Hence, the development and the utilization the numerical control processing play a role and become the development direction in the advancement of manufacturing industry.Based on the analysis of operating principle and process of six-station automatic control knife rest of numerically controlled lathe, this paper determines its solution approach and conclusion. The paper first discusses how to choose such critical pieces of the knife rest of numerically controlled lathe as indexing mechanism, positioning mechanism, drive servo motors, and then discusses the design of worm gear, worm drive, and the structure of principle axis of the knife rest, etc.. The paper then concludes the requirements of common six-station automatic control cutter of numerically controlled lathe.Key words: six-location; electronic knife rest 第一章 引言 毕业设计的背景及目的。机械制造业是一个国家或地区经济进展的重要支柱,其进展水平标志着该国或地区经济的实力、科技水平、生活水准和国防实力。国际市...
