I无锡太湖学院信机系机械工程及自动化专业毕业设计论文任务书一、题目及专题1、题目M2120内圆磨床的改造设计2、专题二、课题来源及选题依据本课题来源于与无锡开源机床集团有限公司合作改造项目。磨床是金属切削行业的一个重要分支，随着工业的发展，对机械零件的加工精度及表面粗糙度的要求日益提高，磨削加工显得更加重要，当前的磨削技术已无法满足要求，所以要提高磨削技术的水平以达到现代工业磨削加工所要求的的精度和效率。尤其在汽车、电力、船舶、冶金、军工、航空航天等行业。数控内圆磨床对被加工零件的适应性很强，具有较高的生产率、加工精度和稳定的加工质量。为了提高加工精度、尺寸精度，本次设计针对数控内圆磨床进给部件进行改造设计。三、本设计（论文或其他）应达到的要求在了解M2120磨床的基础上，设定改造方案。完成改造后的磨床的磨头部件改造设计，绘制磨头装配图；完成M2120内圆磨床的非标准零件图设计，绘制三张零件图；完成设计说明书一份，有方案拟定，必要的分析、计算。四、接受任务学生机械92班姓名祁耀华五、开始及完成日期自2012年11月12日至2013年5月25日六、设计（论文）指导（或顾问）指导教师签名签名签名教研室主任学科组组长研究所所长签名系主任签名2012年11月12日编号无锡太湖学院毕业设计（论文）相关资料题目M2120内圆磨床的改造设计信机系机械工程及自动化专业学号0923098学生姓名祁耀华指导教师许菊若（职称副教授）（职称）2013年5月25日目录一、毕业设计（论文）开题报告二、毕业设计（论文）外文资料翻译及原文三、学生“毕业论文（论文）计划、进度、检查及落实表”四、实习鉴定表无锡太湖学院毕业设计（论文）开题报告题目M2120内圆磨床的改造设计信机系机械工程及自动化专业学号0923098学生姓名祁耀华指导教师许菊若（职称副教授）（职称）2012年11月30日课题来源与无锡开源机床集团有限公司合作改造科学依据（包括课题的科学意义；国内外研究概况、水平和发展趋势；应用前景等）（1）课题科学意义磨削技术及磨床技术在机械制造行业占有极其重要的位置，磨削技术发展很快，在机械加工中起着非常重要的作用。随着高精度、高硬度机械零件数量的增加，以及精密铸造和精密锻造工艺的发展，磨床的性能、品种和产量都在不断的提高和增长。（2）国内外研究状况，水平和发展趋势由于内圆磨床应用十分广泛，近年来，磨削技术得到了飞速发展，各种磨削新技术、新工艺和新成品层出不穷。国际上有不少著名制造商，如日本的OKAMMOTO、MITSUI三井，德国的BLOHM、ELB、ABA，瑞士的MAGERLE，意大利的FAVRATO等。在发展数控内圆磨床生产数量的同时，还要努力提高数控磨床的质量和精度。由于CBN砂轮的使用，强力磨削突破传统磨削的限制，生产倍率成倍提高，目前磨削线速度已高达120M/S，大吃深缓进给的强力磨削也得到了广泛应用。现代高精度磨削技术的发展，磨削尺寸精度达到0103M，表面粗糙度达到02005M，磨削表面变质层的残留应力均很小，明显提高了加工零件的质量。数控是内圆磨床发展的重要方面。在相当长的时期里，国外磨床的数控化率远远低于车床和铣床。在近十年来，由于数控技术的发展，适用于磨床的数控系统也有了较大发展，数控系统的性价比大大提高。目前国内高速磨削应用面不广，磨削速度一般不超过60M/S，与国外相差较大，磨削效率也相对较差，大吃深缓进给的强力磨削方法在我国生产中应用不多。随着我国机械制造业迅猛发展，国内对数控机床的要求也越来越高，自主研发了高精度机床，在控制技术方面与国外差距还很大，主要采用PLC控制为主。国内各机床厂和机床研究所对数控磨床及磨削技术的发展投入很大，取得了一些初步进展，如CIMT展出的上海机床厂的MKY7875、云南MIGHTY公司的SGS618II、威海机床厂的MJ7116等。研究内容本次设计主要针对数控磨床做部分改造，以适应加工产品时可以简单加工、精确定位、保证尺寸，提高加工效率，减轻工人劳动强度。此次改造对机床的导轨和驱动等进给部件做一定的修改，以适应产品的需要，保证在生产中的精度及效率。1采用伺服电机作驱动元件便于实现自动控制；2把原来滑动丝杠螺母副改为滚珠丝杠螺母副，便于实现回转运动转变为直线运动；3采用滚动导轨拟采取的研究方法、技术路线、实验方案及可行性分析到无锡开源机床实地考察，了解内圆磨床各部件结构，针对要改造的部件着重分析，确定进给部件需要改进的部分，作测绘画出部件、零件草图，根据主要参数、结构性能确定总设计方案计算分析，选定材料和标准件，定出尺寸，并确定各部件尺寸使用画图软件AUTOCAD画出装配图及零件图整理材料，出成果，把成果运用到实际中，得出实验结果，做设计总结研究计划及预期成果研究计划2012年10月12日2012年12月31日按照任务书要求查阅论文相关参考资料，完成毕业设计开题报告书。2013年1月1日2013年1月27日学习并翻译一篇与毕业设计相关的英文材料。2013年1月28日2013年3月3日毕业实习。2013年3月4日2013年3月17日本磨床的的主要参数计算与确定。2013年3月18日2013年4月14日本磨床总体结构改造设计。2013年4月15日2013年4月28日零件图及三维画图设计。2013年4月29日2013年5月21日毕业论文撰写和修改工作。预期成果根据提供的主要构件参数而计算出的传动构件的参数，尺寸及机体等是合理的，并且通过对本磨床滚动丝杠螺母和进给部分的改进，最终提高本磨床的精度，效率及自动化程度。特色或创新之处采用伺服电机作驱动元件，使用半闭环紧急系统提高精度效率采用滚珠丝杠螺母副，便于实现回转运动转变为直线运动；采用滚动导轨已具备的条件和尚需解决的问题实验方案思路已经非常明确，已经具备内圆磨床主要参数及其结构、性能，并且已经掌握AUTOCAD绘图软件，画出装配图及零件图加强AUTOCAD绘图能力，加强计算分析能力指导教师意见指导教师签名年月日教研室（学科组、研究所）意见教研室主任签名年月日系意见主管领导签名年月日英文原文MECHANICALDESIGNABSTRACTAMACHINEISACOMBINATIONOFMECHANISMSANDOTHERCOMPONENTSWHICHTRANSFORMS,TRANSMITSEXAMPLESAREENGINES,TURBINES,VEHICLES,HOISTS,PRINTINGPRESSES,WASHINGMACHINES,ANDMOVIECAMERASMANYOFTHEPRINCIPLESANDMETHODSOFDESIGNTHATAPPLYTOMACHINESALSOAPPLYTOMANUFACTUREDARTICLESTHATARENOTTRUEMACHINESTHETERM“MECHANICALDESIGN“ISUSEDINABROADERSENSETHAN“MACHINEDESIGN“TOINCLUDETHEIRDESIGNTHEMOTIONANDSTRUCTURALASPECTSANDTHEPROVISIONSFORRETENTIONANDENCLOSUREARECONSIDERATIONSINMECHANICALDESIGNAPPLICATIONSOCCURINTHEFIELDOFMECHANICALENGINEERING,ANDINOTHERENGINEERINGFIELDSASWELL,ALLOFWHICHREQUIREMECHANICALDEVICES,SUCHASSWITCHES,CAMS,VALVES,VESSELS,ANDMIXERSKEYWORDSMECHANICALDESIGNMECHANISMSDESIGNPROCESSTHEDESIGNPROCESSDESIGNINGSTARTSWITHANEEDREALEXISTINGAPPARATUSMAYNEEDIMPROVEMENTSINDURABILITY,EFFICIENCY,WEIGHT,SPEED,ORCOSTNEWAPPARATUSMAYBENEEDEDTOPERFORMAFUNCTIONPREVIOUSLYDONEBYMEN,SUCHASCOMPUTATION,ASSEMBLY,ORSERVICINGWITHTHEOBJECTIVEWHOLLYORPARTLYINTHEDESIGNPRELIMINARYSTAGE,SHOULDALLOWTODESIGNTHEPERSONNELFULLYTODISPLAYTHECREATIVITY,NOTEACHKINDOFRESTRAINTEVENIFHASHADMANYIMPRACTICALIDEAS,ALSOCANINTHEDESIGNEARLYTIME,NAMELYINFRONTOFTHEPLANBLUEPRINTISCORRECTEDONLYTHEN,ONLYTHENDOESNOTSENDTOSTOPSUPTHEINNOVATIONTHEMENTALITYUSUALLY,MUSTPROPOSESEVERALSETSOFDESIGNPROPOSALS,THENPERFORMTHECOMPARISONHASTHEPOSSIBILITYVERYMUCHINTHEPLANWHICHFINALLYDESIGNATED,HASUSEDCERTAINNOTINPLANSOMEIDEASWHICHACCEPTSWHENTHEGENERALSHAPEANDAFEWDIMENSIONSOFTHESEVERALCOMPONENTSBECOMEAPPARENT,ANALYSISCANBEGININEARNESTTHEANALYSISWILLHAVEASITSOBJECTIVESATISFACTORYORSUPERIORPERFORMANCE,PLUSSAFETYANDDURABILITYWITHMINIMUMWEIGHT,ANDACOMPETITIVECOSTOPTIMUMPROPORTIONSANDDIMENSIONSWILLBESOUGHTFOREACHCRITICALLYLOADEDSECTION,TOGETHERWITHABALANCEBETWEENTHESTRENGTHSOFTHESEVERALCOMPONENTSMATERIALSANDTHEIRTREATMENTWILLBECHOSENTHESEIMPORTANTOBJECTIVESCANBEATTAINEDONLYBYANALYSISBASEDUPONTHEPRINCIPLESOFMECHANICS,SUCHASTHOSEOFSTATICFORREACTIONFORCESANDFORTHEOPTIMUMUTILIZATIONOFFRICTIONOFDYNAMICSFORINERTIA,ACCELERATION,ANDENERGYOFELASTICITYANDSTRENGTHOFMATERIALSFORSTRESSANDDEFLECTIONOFPHYSICALBEHAVIOROFMATERIALSANDOFFLUIDMECHANICSFORLUBRICATIONANDHYDRODYNAMICDRIVESTHEANALYSESMAYBEMADEBYTHESAMEENGINEERWHOCONCEIVEDTHEARRANGEMENTOFMECHANISMS,OR,INALARGECOMPANY,THEYMAYBEMADEBYASEPARATEANALYSISDIVISIONORRESEARCHGROUPDESIGNISAREITERATIVEANDCOOPERATIVEPROCESS,WHETHERDONEFORMALLYORINFORMALLY,ANDTHEANALYSTCANCONTRIBUTETOPHASESOTHERTHANHISOWNPRODUCTDESIGNREQUIRESMUCHRESEARCHANDDEVELOPMENTMANYCONCEPTSOFANI
