基于plc的搖臂鉆床電氣控制系統(tǒng)的設(shè)計(jì)-全文預(yù)覽
【正文】 搖臂鉆床的工作性能。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)。關(guān)鍵詞：可編程控制器，搖臂鉆床，梯形圖，電氣控制系統(tǒng)Abstract: This paper is to studies the machine process in mon use Z3040 in inside radial drilling machine electric control system improves problem. The aim is solving device plexity, 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目 錄1緒 論............................................................ 1 本課題的選題背景和意義 1 國(guó)內(nèi)外關(guān)于本課題的技術(shù)研究現(xiàn)狀和發(fā)展動(dòng)態(tài) 22 Z3040搖臂鉆床傳統(tǒng)電氣控制系統(tǒng)的原理 3 3 控制電路、信號(hào)及照明電路 3 主電動(dòng)機(jī)的旋轉(zhuǎn)控制 4 搖臂的升降控制 4 立柱和主軸箱的松開(kāi)及夾緊控制 43 基于PLC的Z3040搖臂鉆床電氣控制系統(tǒng)硬件部分的設(shè)計(jì) 53．1 PLC型號(hào)的選擇 5 根據(jù)PLC的物理結(jié)構(gòu) 5 根據(jù)PLC的指令功能 5 根據(jù)PLC的輸入輸出點(diǎn)數(shù) 6 根據(jù)PLC的存儲(chǔ)容量 6 根據(jù)PLC的輸入模塊的類(lèi)型 6 根據(jù)PLC的輸出模塊的類(lèi)型 6 PLC的I/O端口分配表 6 PLC的I/O電氣接線圖的設(shè)計(jì) 84 Z3040搖臂鉆床電氣控制系統(tǒng)軟件部分的設(shè)計(jì) 9 PLC梯形圖程序的優(yōu)化設(shè)計(jì)及程序調(diào)試 9 系統(tǒng)預(yù)開(kāi)程序 9 主電動(dòng)機(jī)的起動(dòng)控制程序 9 搖臂升降控制程序 10 主軸箱和立柱同時(shí)放松或夾緊控制程序.......................... 10 主軸箱和立柱分別單獨(dú)夾緊或放松程序 10 信號(hào)顯示程序 11 電源工作狀態(tài)指示信號(hào)程序 115 結(jié) 論 12 研究成果......................................................
