一种新型的自动售货机用取物箱的设计论文[带图纸].doc

编号无锡太湖学院毕业设计(论文)题目一种新型的自动售货机用取货箱的设计信机系机械工程及自动化专业学号学生姓名指导教师(职称副教授)(职称)2013年5月25日无锡太湖学院本科毕业设计(论文)诚信承诺书本人郑重声明所呈交的毕业设计(论文)一种新型的自动售货机用取货物的设计是本人在导师的指导下独立进行研究所取得的成果,其内容除了在毕业设计(论文)中特别加以标注引用,表示致谢的内容外,本毕业设计(论文)不包含任何其他个人、集体已发表或撰写的成果作品。班级机械94学号0923175作者姓名2013年5月25日III摘要论文主要介绍了一种新型的自动售货机用取物箱的设计过程。在设计过程中还综合各方面因素对设计做了多次改进,简述了自动售货机的原理、分类以及内部结构与电子元件和国内外发展概况。就实际使用中所出现的因防盗板运动方式的不同所引起的取物箱高度过高而导致的取物箱体积增大的问题,提出了解决方法。运用PLC对自动售货机的控制系统做了设计。新型的防盗板联动机构具有结构简单、运动平稳、受力情况好、成本低、加工容易等优点。新型取物箱的结构设计运用了机械设计、机械原理、材料力学、创新思维等多方面的知识,是对所学知识的一次综合考验。此次设计的取物箱大多数零件都是钣金件,因此,为了完成这一设计,我学会了运用SolidEdge三维绘图软件,此软件最大的优点就是具有强大的钣金件建模能力。此外,我还充分利用了AutoCAD软件强大的参数化特征将设计图形显而易懂的呈现在大家面前。关键词自动售货机取物箱防盗板钣金SolidEdgeAutoCADPLCIVAbstractThispapermainlyintroducedanewtypeofvendingmachineinthedesignprocessoftakecontentbox.Alsosynthesizedvariousaspectsfactorinthedesignprocesstodesigndoesimprovedmanytimes,hassummarizedthelimitingconditionandthedomesticdevelopmentsurveywhichthevendingmachines,classification,theinternalstructureandelectroniccomponents,thedomesticandforeigndevelopmentsituation.Accordingtothepracticaluseofguardagainsttheftoccurredbecauseofthedifferentwaysofplatemovementcausedbythecontentboxhighlyexorbitantandtaketheleadtotakecontentboxtheincreaseinsize,solutionsareputforward.IdidtheapplicationofPLCcontrolsystemofthevendingmachinetodothedesignThenewsecurityboardlinkagemechanismpossessessimplestructure,smoothmovement,forceofgood,Lowcost,easyprocessing.Takethenewcontentboxstructuredesignusingamechanicaldesign,mechanicalprinciple,materialmechanics,innovativethinkingandsoonvariousknowledge,istheknowledgeofacomprehensivetest.Thedesignofthetakecontentboxismostpartsmetalsheet,Therefore,inordertofinishthedesign,IlearnedtouseSolidEdge3Ddrawingsoftware.BesidesthatIfullydesignthegraphusingtheAutoCADsoftwareformidableparametrizationcharacteristictorevealeasytounderstandpresentinfrontofus.KeywordsVendingmachineTakecontentboxSecurityboardSheetmetalpartsSolidEdgeAutoCADPLCV目录摘要.................................................................................................................................................................IIIAbstract..............................................................................................................................................................IV1绪论...................................................................................................................................................................11.1课题来源.....................................................................................................................................................11.2本课题的研究内容和意义........................................................................................................................11.2.2设计意义..............................................................................................................................................11.3自动售货机的起源、兴起和普及............................................................................................................11.3.1起源......................................................................................................................................................11.3.2兴起.....................................................................................................................................................21.3.3自动售货机产业的普及.....................................................................................................................21.4自动售货机在国内的发展........................................................................................................................21.5自动售货机在国外的应用........................................................................................................................31.6自动售货机在国外的市场发展................................................................................................................41.7新型自动售货机的新增功能....................................................................................................................42自动售货机的分类...........................................................................................................................................63自动售货机的结构与功能分析.......................................................................................................................73.1结构............................................................................................................................................................73.2功能分析....................................................................................................................................................84自动售货机的控制技术.................................................................................................................................104.1PLC的系统结构.......................................................................................................................................114.2I/O分配表....................................................................................................................
