Z35 摇臂钻床 PLC 控制系统设计——论文摘要本设计是研究机械加工中常用的 Z3040 摇臂钻床传统电气控制系统的改造问题,旨在解决传统继电器—接触器电气控制系统存在的线路复杂、可靠性稳定性差、故障诊断和排除困难等难题。由于 PLC 电气控制系统与继电器—接触器电气控制系统相比，具有结构简单，编程方便，调试周期短，可靠性高，抗干扰能力强，故障率低，对工作环境要求低等一系列优点。因此，本设计对 Z3040 摇臂钻床电气控制系统的改造，将把 PLC 控制技术应用到改造方案中去，从而大大提高摇臂钻床的工作性能。论文分析了摇臂钻床的控制原理，制定了可编程序控制器改造 Z3040 摇臂钻床电气控制系统的设计方案，完成了电气控制系统硬件和软件的设计，其中包括 PLC机型的选择、I/O 端口的分配、I/O 硬件接线图的绘制、PLC 的 SFC 图和梯形图程序的设计，由于没有实物，还进行了仿真电路设计。对 PLC 控制摇臂钻床的工作过程作了详细阐述，论述了采用 PLC 取代传统继电器—接触器电气控制系统从而提高机床工作性能的方法，给出了相应的控制原理图。关键词：可编程控制器；摇臂钻床；电气控制系统；梯形图IAbstractThis design is to studies the machine process in common use Z3040 in inside radial drillingmachine electric control system improves problem. The aim is solving device complexity,inferior reliability and stability, malfunction analysis and trouble obviation of the traditionalrelay electric control system. Because of electric control system PLC there are lots ofadvantages which include design, install, connect the line and adjust to try workload small,the period of research and manufacture is short, reliability is high, the ability of Anti-interference is very strong, the rate of break down is low, the demand of work environmentis low, maintenance convenience a series of advantage etc. Therefore, a work for to theZ3040 radial drilling machine electric control system reforming, will reforming PLC controltechnique application in the project, then increasing radial drilling machine’s work fun...
