摘要组合机床，是由大量的通用部件和少量专用部件组成的工序集中的高效率机床。其特点有结构紧凑、工作质量可靠、设计和制造周期短、投资少、经济效果好、生产率高等。本次设计的题目是铣削组合机床及主轴组件。首先针对所要加工的零件入手，对机床进行总体方案设计，进而确定机床的总体布局，随后，对主轴组件进行设计。在设计主轴组件时，以主轴为线索，在满足刚度、精度等要求下，完成其它（如轴承、轴向调节机构、锁紧机构等）所有零件的设计。设计机械加工工艺规程遵循如下原则1）保证零件图样上所有技术要求的实现。2）必须能满足生产纲领的要求。3）在满足技术要求和生产纲领要求的前提下，要求工艺成本最低，低耗节能。4）尽量减轻工人的劳动强度，保障生产安全。维护环境卫生。本产品是按用户要求而设计的，用户讨论合格后，投入生产，希望指导、鉴定。关键词组合机床，主轴组件，主轴，轴承，轴向调节机构AbstractModularMachine,bythelargenumberofcommonpartsandasmallnumberofspecializedcomponentsoftheprocessfocusedefficientmachine.Itsfeaturesincludecompact,reliablequality,designandmanufacturingcycleshorter,lessinvestmentandeconomiceffects,andhigherproductivity.Thedesignisthesubjectofcombinedmillingmachinespindlecomponents.Firstofall,fortheprocessingofpartstostartwithageneralprogramofmachinedesign,machinetoolandthendeterminetheoveralllayout,thenthedesignofthemaincomponents.Componentsinthedesignofthespindletospindleforclues,tomeetthestiffnessandprecisionrequiredtocompletetheothersuchasbearings,axialadjustmentagencies,locking,etc.thedesignofallparts.Designmechanicalprocessingordertofollowthefollowingprinciples1Toensurethatallpartsdrawingsontherealizationofthetechnicalrequirements.2Programmustbeabletomeetproductionrequirements.3Tomeetthetechnicalrequirementsandrequirementsoftheproductionprogram,underthepremiseoftheminimumrequirementsofcost,lowenergy.4Minimizethelaborintensityofworkers,protectionofproductionsafety.Thisproductisbasedonuserrequirementsanddesign,theuserdiscussionafterpassingtheproduction,hopetheguide,identified.KeywordsModularMachine,spindlecomponents,spindle,bearings,axialadjustment目录绪论................................................................................................................................1第1章机床总体设计...............................................................................................11.1机床总体方案设计的依据................................................................................11.2工艺分析.............................................................................................................11.3机床主要技术参数的确定.................................................................................31.4进给驱动电动机功率的确定.............................................................................5第2章主轴组件要求与设计计算...........................................................................62.1主轴的基本要求.................................................................................................62.2主轴组件的布局.................................................................................................92.3主轴结构的初步拟定.......................................................................................122.4主轴的材料与热处理.......................................................................................132.5主轴的技术要求...............................................................................................132.6主轴直径的选择...............................................................................................142.7主轴前后支承轴承的选择...............................................................................152.8主轴内孔直径...................................................................................................162.9主轴前端悬伸量...............................................................................................172.10主轴支承跨距.................................................................................................182.11主轴结构图.....................................................................................................182.12主轴组件的验算.............................................................................................18第3章主轴组件相关部件.....................................................................................233.1主轴轴承的润滑...............................................................................................213.2主轴组件的密封...............................................................................................213.3轴肩挡圈...........................................................................................................233.4挡圈...................................................................................................................233.5圆螺母...............................................................................................................233.6套筒...................................................................................................................243.7前、后支承的轴承盖.......................................................................................253.8主轴用套筒及其锁紧部分...............................................................................263.9主轴尾部的内花键...........................................................................................273.10主轴组件轴向调节机构.................................................................................283.11箱体设计.........................................................................................................30第4章结论.......................................................................................................
