摘要

Z3040型摇臂钻床适用于单件或批量生产带有多孔的大型零件的孔加工，是

机械加工车间常用的机床，在机械行业中得到了广泛应用。由于传统继电器－

接触器控制的摇臂钻床存在电路接线复杂，触点多、噪音大、可靠性差、故障

诊断与排除困难等缺点，因此对Z3040摇臂钻床控制系统的技术改造是非常必

要的。

本文在分析Z3040型摇臂钻床继电接触控制系统工作原理的基础上，提出

了用可编程控制器（PLC）对摇臂钻床控制系统进行改造设计。文中介绍了PLC

的原理和特点；给出了摇臂钻床PLC控制系统的硬件组成和软件设计；其中包

括PLC的选型、输入/输出（I/O）地址分配、PLC外部接线图、PLC梯形图程序

设计；分析了用PLC控制摇臂钻床的工作过程；对主要电器元件进行了选择。

改造后的Z3040型摇臂钻床简化了控制线路，使机床功能完善，使用方便，

维护简单，降低了设备运行的故障率，提高了设备运行的使用率，可实现生产

过程的高效、节能和低成本。在工业上有广泛的应用前景。
