轴承座夹具设计

摘要根据所给题目轴承座接合面铣铣床卡具设计，设计专用卡具，在制定工艺路线时，主要根据加工工艺原则：先加工基准面再加工其他表面，先安排主要表面的加工在安排次要表面的加工，先粗后精，先主后次加工等基本原则。轴承座接合面铣铣床卡具，主要包括定位元件、夹紧机构、夹具体等部件。在以上结构方案的基础上，创建所有零件的三维实体模型库，并完成夹具整体的三维实体装配模型。本设计主要采用以下技术：通过Ug软件的三维实体建模技术和虚拟装配技术，创建箱体夹具所有零件的三维实体模型库，并完成夹具整体的三维实体装配模型，从而实现面向装配的设计。关键词铣床卡具；工艺路线；三维实体建模；虚拟装配ABSTRACTTurningtothesubjectaccordingtothesideofasmallturretmillingmachinemillingfixturedesign,designspecialfixtures,inthedevelopmentprocessroute,themainprocessingtechnologybasedontheprinciple:first,re-processingofothersurfaceprocessingdatum,thefirstmajorsurfacearrangedinthearrangementsforsecondaryprocessingsurfaceprocessing,thefirstfineafterroughfirstmasterthebasicprinciplesofpost-processingtimes.Smallturretlathemillingfixturesidemilling,includinglocators,clampingmechanism,specificfoldersandothercomponents.Intheaboveprogramonthebasisofthestructure,createallcomponentsofthethree-dimensionalsolidmodellibrary,andcompletethewholethree-dimensionalsolidfixtureassemblymodel.Thisdesignmainlyusesthefollowingtechnologies:Ugsoftwarethroughthree-dimensionalsolidmodelingandvirtualassemblytechnologytocreateallthepartsfixtureboxthree-dimensionalsolidmodellibrary,andcompletethefixtureassemblyoftheoverallthree-dimensionalsolidmodelToachievedesignforassembly.KeywordsMillingfixture；processroute；Three-dimensionalsolidmodeling；VirtualAssembly目录1.1零件的作用................................................................................................................................11.2零件的工艺分析........................................................................................................................11.2.1零件图样分析........................................................................................................................11.2.2工艺分析...............................................................................................................................11.3零件表面粗糙度........................................................................................................................21.4本章小结...................................................................................................................................2第二章工艺规程设计...............................................................................................................32.1定位基准的选择........................................................................................................................32.1.1精基准的选择........................................................................................................................32.1.2粗基准的选择........................................................................................................................32.2拟定工艺路线............................................................................................................................32.2.1表面加工方法的确定............................................................................................................32.2.2加工阶段的划分....................................................................................................................42.2.3工序的集中和分散...............................................................................................................42.2.4工序顺序的安排...................................................................................................................42.2.5加工设备的选用....................................................................................................................42.3工艺路线的确定........................................................................................................................42.4本章小结...................................................................................................................................5第三章“铣接合面”工序夹具设计...............................................................................................53.1夹具的定义及分类...................................................................................................................53.2设计机床夹具的方法和步骤....................................................................................................53.2.1确定工件的定位方法............................................................................错误!未定义书签。3.2.2确定工件的加紧方式和设计加紧机构................................................错误!未定义书签。3.2.3绘制零件图和标注零件图各部分主要尺寸，公差配合和技术要求错误!未定义书签。3.2.4绘制夹具总装配图................................................................................错误!未定义书签。3.3设计机床夹具时应注意的问题................................................................................................81.1零件的作用................................................................................................................................11.2零件的工艺分析........................................................................................................................11.2.1零件图样分析........................................................................................................................11.2.2工艺分析.......................................................................................................................
