摘要PAGEIV铣曲轴工艺定位面铣床夹具摘要本次毕业设计题目为铣曲轴工艺定位面铣床夹具,铣床类夹具主要用于加工零件上的平面、键槽、缺口及成型表面等。由于铣削加工的切削力较大,又是断续切削,加工中易引起振动,因此要求铣床夹具的相应的元件要有足够的强度,夹紧力应足够大,且有较好的自锁性。此外,铣床夹具一般通过对刀装置确定刀具与工件的相对位置,其夹具体底面大多设有定向键,通过定向键与铣床工作台T形槽的配合来确定夹具在机床的正确位置。夹具与铣床的工作台上的连接还要通过螺栓紧固,因此在设计中综合地考虑了相关安装尺寸。在现代制造技术迅猛发展的今天,机床夹具无论在传统机床上还是在数控机床、加工中心上,仍是必不可少的重要工艺装备。通过机床夹具设计,我们不仅可以培养综合运用已学知识的能力而且可以得到工程设计的综合训练。关键词:曲轴,定位,铣床,强度,自锁CRANKSHAFTMILLINGMACHINEFIXTURESURFACEPOSITIONINGTECHNOLOGYABSTRACTThegraduationprojectentitledTechnologicalPositioningCrankshaftmillingmachinefixturetypeface,clamp-typemillingmachinemainlyusedforprocessingpartsoftheplane,keyway,andthegapandformingsurface.Millingofthecuttingforceduetothelarger,butalsointermittentcutting,processingiseasytocausevibration,thereforerequestedthemillingmachinecomponentscorrespondingfixtureshouldhavesufficientstrength,clampingforceshouldbelargeenough,andhavebetterself-lockingof.Inaddition,themillingcutterfixturedevices,usuallyderivedbythetoolandtheworkpiecetodeterminetherelativeposition,thefolderhasdirectedmostofthespecifickeybottom,throughthedirectionalkeysandthemillingtablewithT-shapedslotinthemachinetoolfixturetodeterminethecorrectposition.Millingmachinefixtureandconnecttheworkplatformthroughfasteningbolts,sothedesignofanintegratedconsiderationoftherelevantinstallationsize.Intherapiddevelopmentofmodernmanufacturingtechnologyoftoday,bothinthetraditionalfixtureonthemachineorCNCmachinetools,machiningcenterisstillanimportanttechniqueandequipmentisessential.FixtureDesignthroughthemachine,wecandeveloptheintegrateduseofnotonlyhastheabilityandknowledgeengineeringcanbeintegratedtraining.KEYWORDS:crankshaft,positioning,millingmachines,strength,self-locking前言目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc231984976"前言PAG
