Z3040型摇臂钻床电气控制系统设计 摘要：本课程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，本论文对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梯形图程序的设计。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;梯形图;电气控制系统? Abstract: this course is designed to research that is commonly used in mechanical processing Z3040 radial drilling machine traditional electric control system transformation problem, aims to solve the traditional relay - contactor electric control system of circuit complexity, reliability difficult problems such as poor stability, failure diagnosis and elimination. Due to the PLC electrical control system compared with the relay - contactor electric control system, has the advantages of simple structure, convenient programming, commissioning period is short, high reliability, strong anti-interference ability, low failure rate, low requirement for working environment a series of advantages. Therefore, this paper Z3040 radial drilling machine electric control system transformation, the PLC control technology into the reform scheme, thus greatly improving the performance of radial drilling machine. Paper analyzes the control principle of radial drilling machine, formulated by programmable controller reforming Z3040 radial drilling machine electric control system design, completed the electrical control system hardware and software design, including PLC type choice, the distribution of the I/O ports, I/O hardware wiring diagram drawing, PLC ladder diagram design of the program. For PLC control of radial drilling machine, and gives a detailed description of the working process, this paper discusses the PLC to replace the traditional relay - contactor electric control system to improve the working performance of the ma
