加工中心自动换刀装置自动控制过程设计

加工中心自动换刀装置自动控制过程设计ee（ee）指导老师：ee[摘要]本设计的题目是加工中心自动换刀装置自动控制过程设计。通过分析刀库的自动换刀的过程，使刀库在加工中心上能配合换刀机械手的需要——能在数控程序的控制下灵活的实现换刀过程,每次换新刀只需输入相应换刀号信号即可。在分析控制要求的基础上，设计出相应控制程序。控制程序包含：建立当前刀具库映像、记录请求刀具号、转盘转动方向判断并确定转盘正反转、发出脉冲控制刀盘转动、到位灯及换刀指示灯显示等部分,程序结构性好、可读性强、运行效率高，能很好地满足实用要求。[关键词]自动换刀自动控制过程MachiningCenterToolChangeControlSystemDesignee(ee)Teacher:ee[Abstract]thisdesigntopicisbasedonthemachiningcentertoolchangecontrolsystemdesign.Throughtheanalysisoftheknifeoftheautomatictoolchangingprocess,sothatthecutterinmachiningcentercanbematchedwiththetoolchangingmanipulatorneeds--inNCprogramunderthecontrolofflexibleimplementationtoolchangingprocesseverytimenewknifeonlyneedstoinputthecorrespondingtoolchangesignalcanbe.Theanalysisandcontrolonthebasisoftherequirements,designsthecorrespondingcontrolprocedure.Thecontrolprogramincludes:establishthelibraryimage,recordingrequesttoolnumber,therotationoftheturntabledirectionjudgmentandtodeterminetheturntableisreversed,tosendpulsestocontrolthecutterdisctorotateinplace,lightsandtoolchangeindicatordisplayparts,goodprogramstructure,readabilityisstrong,operationefficiencyishigh,whichcanmeetthepracticalrequirements.[Keywords]theknifeoftheautomatictoolchangingautomaticcontrolsystemeeI目录目录.........................................................................................................................................I引言........................................................................................................................................11PLC在加工中心中的应用.....................................................................................................51.1数控加工中心组成结构及工作过程.........................................................................51.2数控机床中PLC和NC的关系................................................................................71.3PLC在数控机床中的应用.........................................................................................91.3.1PLC在数控机床中的应用形式.......................................................................91.3.2PLC与数控系统及数控机床间的信息交换...................................................91.3.3PLC与数控机床外围电路的关系.................................................................102刀库自动选刀系统.................................................................................错误!未定义书签。2.1刀库自动选刀机械系统..............................................................错误!未定义书签。2.2刀库选刀方式.............................................................................错误!未定义书签。2.3驱动装置步进电机工作原理与控制..........................................错误!未定义书签。2.3.1步进电机工作原理和特性..............................................错误!未定义书签。2.3.2基于PLC步进电机的控制原则.....................................错误!未定义书签。2.3.3控制系统结构...................................................................错误!未定义书签。3选刀控制的PLC系统设计...................................................................错误!未定义书签。3.1三菱PLC及其原理.....................................................................错误!未定义书签。3.1.1PLC系统组成及各部分的功能.......................................错误!未定义书签。3.1.2PLC的基本工作原理.......................................................错误!未定义书签。3.2编程方法与规则..........................................................................错误!未定义书签。3.2.1编程要求..........................................................................错误!未定义书签。3.2.2编程方法..........................................................................错误!未定义书签。3.3CCNC与PLC的通信.................................................................错误!未定义书签。3.4PLC型号的选择分析..................................................................错误!未定义书签。3.5PLC地址分配..............................................................................错误!未定义书签。3.6PLC接线图..................................................................................错误!未定义书签。4换刀控制过程........................................................................................错误!未定义书签。4.1换刀总过程..................................................................................错误!未定义书签。4.1.1换刀控制实现的功能.......................................................错误!未定义书签。4.2换刀程序过程..............................................................................错误!未定义书签。4.2.1建立刀具库映像...............................................................错误!未定义书签。4.2.2换刀号输入.......................................................................错误!未定义书签。4.2.3得出换刀号所在的刀座号...............................................错误!未定义书签。4.2.4判断刀盘转动方向并得出控制刀盘转动脉冲数...........错误!未定义书签。4.2.5发出脉冲以及控制指示灯...............................................错误!未定义书签。4.3三菱FX2N指令使用.................................................................错误!未定义书签。4.4程序流程图..................................................................................错误!未定义书签。5程序梯形图............................................................................................错误!未定义书签。6编程环境.................................................................................................错误!未定义书签。6.1GXDeveloper的特点..................................................................错误!未定义书签。6.2GXDeveloper的环境...................................................
