摘要 PAGE IV w 多工步组合机床的PLC控制系统设计 摘要 随着社会与科学技术的不断进步和发展，组合机床及其自动化生产线在工业生产当中扮演着越来越重要的角色，其先进性和技术水平在很大程度上决定着相关部门的生产效率。随着机床电气控制技术的不断发展和可编程控制器的广泛应用，可编程序控制技术以其灵活性好，可靠性高，通用性强，逐渐取代了传统继电器控制方式，PLC对组合机床的应用，无疑是当今工业控制的主要发展方向。本文将可编程控制器应用于多工步组合机床的电气控制系统设计，并对设计思想作了详细介绍。通过对多工步组合机床的控制系统的分析，设计好系统的主电路和控制电路， PLC的外部接线图，以及编写好控制程序顺序功能图和梯形图等。 关键词：多工步组合机床，PLC，步进顺序控制 Design of much work step machine tool control system of PLC ABSTRACT As the development of society and science technology, modular machine tool with its automatic line has play a more and more important role in Industry production, which has largely determined the productivity of the related department due to its advancement and technical. Along with the electrical control of machinery tools and the wide application of PLC, it has gradually substituted for the traditional relay-control because of its very flexibility, good reliability and great commonality, which is no doubt to be the major direction of the contemporary industry area.this paper mainly introduces the applying of PLC to the many stages drilling modular tool control system and explains the designing idea. By analyzing the control system, finally designed the main circuit and the controlling circuit, drawn out the external wiring diagram of PLC, and completed the sequence functional diagram, ladder diagram of control program etc. KEY WORDS: Many stages drilling modular tool，PLC，Stepping sequence control 前言 目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc295390545 前　言 PAGEREF _Toc295390545 \h 1 HYPERLINK \l _Toc295390546 第1章 组合机床的发展 PAGEREF _Toc295390546 \h 2 HYPERLINK \l _Toc295390547 1.1背景 PAGEREF _Toc295390547 \h 2 HYPERLINK \l _Toc295390548 1.1.1组合机床国内外现状 PAGEREF _Toc295390548 \h 3 HYPERLINK \l _Toc295390549 1.1.2 PLC应用技术的国内外现状 PAGEREF _Toc295390549 \h 4 HYPERLINK \l _Toc295390550 1.2 可编程控制器及其应用 PAGEREF _Toc295390550 \h 5 HYPERLINK \l _Toc295390551 1.2.1可编程控制器的定义 PAGEREF _Toc295390551 \h 5 HYPERLINK \l _Toc295390552 1.2.2可编程控制器的结构 PAGEREF _Toc295390552 \
