长春汽车工业高等专科学校 毕 业 实 践 报 告 题目/实践 壳体类零件攻丝组合机床的PLC控制系统设计毕业论文 中 文 摘 要 本文介绍壳体类零件攻丝组合机床的PLC控制系统设计，该系统具有自动化程度高，精度高等特点，在工业生产等领域有广泛应用。传统的组合机床采用继电器，精度低，可靠性不高，已不适合社会发展需要。随着PLC控制技术的迅速发展，以PLC为核心的组合机床控制系统已凸显出其优势。 本文首先介绍PLC和组合机床的历史与发展，并着重论述了组合机床的结构和运动形式以及控制方式，接着对PLC的组成和结构进行了分析，并对PLC控制系统的总体设计和程序的表达方式做了概述，然后确定PLC型号、分配I/O地址和外部配线，接着根据相关内容画出顺序功能图并利用FXGP-WIN-C软件画出PLC梯形图。在文章的最后还介绍了PLC控制系统的安装和维护以及对论文的进一步总结。 关键字：PLC；三菱FX系列；组合机床；壳体类零件；攻丝 Abstract This article introduced that the PLC control system design of the shell kind parts tapping combined machine tool, this system has a high degree of automation and precision, and also be widely used in industrial production and other fields. The traditional combined machine tool uses the relays generally, the precision is low, the reliability is not high, did not meet the social development need. Along with the PLC control technologys rapidly expand, as the core combined machine tool has highlighted its superiority take PLC. This paper first introduced that PLC and the history and development of the combined machine tools, and emphatically expounds the structure, movement and the control mode of combined machine tools, then the composition and structure of PLC is analyzed, besides these, the general arrangement of PLC control system and the presentation of program are also given an overview, then we confirm PLCs type, distribute I/O address and external wiring. According to the related content we draw sequential function chart and use FXGP-WIN-C software to draw PLC ladder diagram. At the end of the article we also introduced installation and maintenance of PLC control system and further summary fo the article. Key words: PLC ；Mitsubishi FX series；combined machine tools； shell kind parts；tapping 目录 中文摘要 Abstract 第一章 概述 1 1.1 组合机床概述............................................ 1 1.2 组合机床的发展.......................................... 1 1.3 组合机床装配模型........................................ 1 1.4 组合机床及其体系结构的发展现状....................... .....2 1.5 本章小
