摘 要
本論文是研究機(jī)械加工中常用的Z3040搖臂鉆床傳統(tǒng)電氣控制系統(tǒng)的改造問題,旨在解決傳統(tǒng)繼電器—接觸器電氣控制系統(tǒng)存在的線路復(fù)雜、可靠性穩(wěn)定性差、故障診斷和排除困難等難題。由于PLC電氣控制系統(tǒng)與繼電器—接觸器電氣控制系統(tǒng)相比，具有結(jié)構(gòu)簡(jiǎn)單，編程方便，調(diào)試周期短，可靠性高，抗干擾能力強(qiáng)，故障率低，對(duì)工作環(huán)境要求低等一系列優(yōu)點(diǎn)。因此，本論文對(duì)Z3040搖臂鉆床電氣控制系統(tǒng)的改造，將把PLC控制技術(shù)應(yīng)用到改造方案中去，從而大大提高搖臂鉆床的工作性能。論文分析了搖臂鉆床的控制原理，制定了可編程控制器改造Z3040搖臂鉆床電氣控制系統(tǒng)的設(shè)計(jì)方案，完成了電氣控制系統(tǒng)硬件和軟件的設(shè)計(jì)，其中包括PLC機(jī)型的選擇、I/O端口的分配、I/O硬件接線圖的繪制、PLC梯形圖程序的設(shè)計(jì)。對(duì)PLC控制搖臂鉆床的工作過程作了詳細(xì)闡述，論述了采用PLC取代傳統(tǒng)繼電器—接觸器電氣控制系統(tǒng)從而提高機(jī)床工作性能的方法，給出了相應(yīng)的控制原理圖。

Abstract: This paper is to studies the machine process in common use Z3040 in inside radial drilling machine electric control system improves problem. The aim is solving device complexity, inferior reliability and stability, malfunction analysis and trouble obviation of the traditional relay electric control system. Because of electric control system PLC there are lots of advantages 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 environment is low, maintenance convenience a series of advantage etc. Therefore, a work for to the Z3040 radial drilling machine electric control system reforming, will reforming PLC control technique application in the project, then increasing radial drilling machine’s work function. The paper introduces to the control principle of the radial drilling machine. Established the programmable controller improve the design project of electric control system of Z3040 radial drilling machine. Completed the design of the software and hardware of the electric control system, Among them include the model of PLC choice、the I/O allotment of the address、the I/O hardware connects the line diagram、PLC trapezium diagram’s design. It explains that PLC control the work process of radial drilling machine. Discussing the adoption PLC replaces the traditional electric control system’s method and increases the work function of radial drilling machine, give a homologous control principle diagram.
Key words: PLC，Radial drilling machine，Trapezium diagram，Electric Control System
