车床电气及可编程控制系统研究作者姓名:周宏威专业名称:电气工程及其自动化指导教师:王安讲师摘要多年来，可编程控制器（以下简称PLC）从其产生到现在，实现了接线逻辑到存储逻辑的飞跃；其功能从弱到强，实现了逻辑控制到数字控制的进步；其应用领域从小到大，实现了单体设备简单控制到胜任运动控制、过程控制及集散控制等各种任务的跨越。今天的PLC在处理模拟量、数字运算、人机接口和网络的各方面能力都已大幅提高，成为工业控制领域的主流控制设备，在各行各业发挥着越来越大的作用。论文介绍了PLC在普通卧式车床中的应用，给出了普通卧式车床电气控制的软、硬件设计，基于PLC设计出完整的车床电气控制系统。硬件部分介绍了利用PLC进行控制系统设计的步骤；软件部分阐述了程序设计思路，并给出I/O接口，梯形图。本系统既可以用于新型车床的开发也可以用于车床的数控改造。关键词：可编程控制器单体设备简单控制工业控制AbstractFormanyyears,theprogrammablecontroller(hashereafterreferredtoasPLC)toproducefromittothepresent,hasrealizedthewiringlogictothestoredlogicleap;Itsfunctionfromweakonestostrongones,realizedlogictocontrolthenumericalcontroltheprogress;Itsapplicationdomainfrominfancytomaturity,realizedthemonomerequipmenttocontrolthecompetentmovementcontrol,theprocesscontrolandthecollectionanddistributioncontrolsimplyandsooneachkindofdutyspanning.TodayPLCintheprocessingsimulationquantity,thedigitaloperation,theman-machineconnectionandnetworkvariousaspectsabilityalllargelyenhanced,becomestheindustrycontroldomainthemainstreamcontroldevice,isplayingthemoreandmoremajorroleinallthevarioustradesandoccupations.ThewholesystemhasadoptedaPLCtocontrol,thewholecontrolsystemsetsupacontrolroomandutilizeaPLCcontrolmillingmachinetorun.Itrealizedthefunctionofmillingmachine’sstartorstop,troublestop,stoppromptly.Andithastwokindsofcontrolmethodsthemanuallycontrolandautomaticallycontrol,thusrealizedtheautomaticfunctionofthemillingmachine’soperation.Keywords:PLC,Monomerequipmentsimplecontrol,Industrycontrol目录摘要...........................................IAbstract.......................................II目录.........................................III前言...........................................11.车床的简介、发展及组成..........................31.1车床简介.................................................................................31.2车床的发展和分类.................................................................31.3普通车床的组成及功用.........................................................51.4车床的使用.............................................................................72.PLC基础知识及工作原理..........................92.1PLC基础知识..........................................................................92.2PLC的基本工作原理............................................................132.2.1PLC的工作过程......................................................................132.2.2PLC工作方式..........................................................................152.3PLC控制与继电器控制的区别...........................................162.4PLC控制系统的设计基本原则............................................172.5PLC的应用选型....................................................................173.普通卧式车床的电气控制线路.....................223.1车床电气控制线路设计要求...............................................223.2CM6132普通车床的电气控制线路分析..............................233.3C650普通车床的电气控制线路分析...................
