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。

Abstract
This article introduced that the PLC control system design of the shell kind parts bined machine tool, this system has a high degree of automation and precision, and also be widely used in industrial production and other fields. The bined 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 technology's rapidly expand, as the bined machine tool has highlighted its superiority take PLC.
This paper first introduced that PLC and the history and development of bined machine tools, and emphatically expounds the structure, movement and the control mode bined machine tools, then position 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 PLC's 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 bined machine tools, shell kind parts、tapping
