毕业设计（论文）设计（论文）题目：简易自动门的设计学院名称：机械工程学院专业：******班级：********姓名：******学号：*******指导教师：******职称：******定稿日期：2016年月日诚信承诺我谨在此承诺：本人所写的毕业论文《简易自动门的设计》均系本人独立完成，没有抄袭行为，凡涉及其他作者的观点和材料，均作了注释，若有不实，后果由本人承担。承诺人（签名）：年月日中文摘要I摘要本设计是实际生活中的自动感应门为模型进行设计，自动门系统主要由可编程控制器（PLC）、感应器件、驱动装置和传动装置组成。驱动装置通过直流电机进行驱动整个门的左右移动，电机采用自动门专用电机，最大转速为200r/min，电机功率为75W，自动门的移动速度为200-450mm/s，自动门的机械传动部分采用同步带轮实现直线移动，将门架安装在同步带上，为了防止门将同步带压弯或者压变形增加导轮装置进行承载，设计两组导轮装置进行承压。横梁采用槽钢固定在墙体上，整个驱动装置和传动装置固定在槽钢上。自动门控制部分的主要工作原理是感应器件将检测到的人体或物体信号传送到PLC，PLC再综合收到的自动门状态信号作出判断，而后发出控制信号，使驱动装置运行，在通过传动装置带动门的动作。关键词：自动门；驱动装置；传动装置；PLC英文摘要IAbstractThisdesignistheautomaticinductiondoorinactuallifeasamodelfordesign,automaticdoorsystemismainlycomposedofprogrammablecontroller(PLC),inductiondevice,drivingdeviceanddrivingunit.Drivethroughthedcmotordrivesthedooraroundmobile,motoradoptsautomaticdoorspecialmotor,themaximumspeedof200r/min,themotorpoweris75w,automaticdoormovementspeedfor10to50cm/s,automaticdoorsofthemechanicaltransmissionpartadoptssynchronousbeltwheeltorealizelinearmovement,insynchronizationwiththedoorframeinstallation,inordertopreventthegoalkeepersynchronousbeltbendingorpressuredeformationincreasebearingrollerdevice,designtwosetsofrollerdeviceisunderpressure.Beamsusingchannelfixedonthewall,thedriveandtransmissiondeviceisfixedonthechannel.ThemainworkingprincipleofautomaticdoorcontrolpartissensorwilldetectthehumanbodyorobjectsignalstoPLC,PLCintegratedautomaticdoorstatehavereceivedsignalstojudge,andthenacontrolsignals,drivingdevice,operation,throughthetransmissiongeardrivethemovementofthedoor.Keywords:Automaticdoor;Drive;Transmissiondevice;PLC目录I目录1.绪论..........................................................................................................................11.1自动门概述......................................................................................................................11.2自动门的发展现状..........................................................................................................11.3自动门的常见分类.........................................................................................................21.4本课题的主要任务..........................................................................................................32.自动门的机械部分设计................................................................................................42.1主运动方案设计..............................................................................................................42.2简易自动门方案的确定..................................................................................................42.3机械传动的计算..............................................................................................................52.3.1驱动装置的计算........................................................................................................52.3.2传动比的计算............................................................................................................62.3.3同步轮的计算............................................................................................................72.3.4滚动轮的校核..........................................................................................................103.自动门控制部分设计..................................................................................................133.1PLC控制程序设计......................................................................................................133.2自动门控制系统总体方案设计....................................................................................143.3系统设计的基本步骤....................................................................................................143.4功能器件的基本工作原理............................................................................................143.4.1简易自动门的基本工作原理..................................................................................143.4.2行程开关(限位开关)的工作原理............................................................................153.4.3光电开关介绍..........................................................................................................153.5自动门控制系统软件的设计........................................................................................163.5.1程序流程图..............................................................................................................165.4机械手的梯形图.............................................................................................................163.5.2电气原理图..............................................................................................................173.5.3I/O分配表................................................................................................................183.5.4梯形图.....................................................................................................................18总结............................................................................................................................20致谢..............................................................................................................................21目录II参考文献.
