济南大学毕业设计--毕业设计题目电子拉力弹簧试验机的设计摘要电子拉力弹簧试验机，主要用于测试弹簧或者其他弹性器件的受力与变形之间的量值关系，确定试件的品质，进而对试件的加工工艺、工序是否合理做出正确的判断，为合理修正、提高工序能力提供科学依据。本产品主要应用于弹簧制造、低压电器、家用电器、轻工纺织、军工机械、科研、院校等部门。本电子拉力弹簧试验机采用伺服电机作为动力源，为了增大传动比，采用蜗轮蜗杆减速机减速，滚珠丝杠系统制造精密，稳定可靠，用单片机实现对电机转速的控制，可随时控制压盘上下移动的距离，能够实现手动加载，具有超行程保护功能。整机框架采用封闭式结构，结构紧密，造型美观，安全可靠、操作方便。本次毕业设计在充分了解试验机知识的基础上，整合了电子拉力弹簧试验机的优点，对普遍存在的问题进行了改善，做了进一步提高。关键词：试验机；弹簧；单片机；伺服电机；ABSTRACTElectronictensilespringtestingmachine,Mainlyusedtotestthespringsorotherelasticdevicesbetweenforceanddeformationvaluerelationship，的determinethequalityofthespecimen,Andthenprocessthespecimen,whetheritisreasonableprocedurestomaketherightjudgments,reasonableamendmentstoimprovetheprocesscapabilitytoprovidescientificevidence.Thisproductismainlyusedinspringmanufacture,low-voltageelectricalappliances,householdappliances,lighttextile,militarymachinery,scientificresearchinstitutionsandotherdepartments.Theelectronictensiletestmachineusingservomotorasapowersource，Toincreasethetransmissionratio，Wormgearreducerused，Manufactureofprecisionballscrewsystems，Stableandreliable，WithMCUcontrolofmotorspeed，，Controlthepressureplatecanmoveupordownatanydistance，，Canbeachievedmanuallyloaded,Withover-travelprotection。Machineframeismadeofclosed-endstructure，Compact,attractiveappearance,safe,reliable,easytooperate.Thegraduationbasedoninthefullknowledgeandunderstandingofthetestmachine，Theintegrationofelectronictensiletestmachinespringsadvantages，Issuesofcommonimprovementsmadetofurtherimprove.Keywords：testingmachine;spring;SCM;servomotor;目录摘要……………………………………………………………..…….….……………...=1\*ROMANIABSTRACT………….……………….……………………..…………….=2\*ROMANII1前言……….…………………………………………………………….….……………..11.1国内外研究现状、水平及存在的问题................………….………….………..11.2选题目的目的及意义.........................……….......…………….………….………..11.3实施方案及主要研究方案..........…………………………….…....……..………11.4课题创新之处......................…....………........…………………….…....……….11.5预期研究成果......................…....………...
