I摘要本论文主要分析了ZS1105柴油机箱体加工工艺规程及专用夹具的设计。分析了其各面和孔的加工方法及切屑余量等参数,制定了三条加工工艺路线,并从中选取了最为合理的一条,该路线计算出时间定额,选取适合的机床和刀具制作相应的工序过程卡片。本论文针对其中精糛中间大孔这道工序设计了镗床专用夹具。绘制出机床联系尺寸图表达夹具与机床相对位置关系,绘制加工示意图表达工件定位及镗杆的选择,最后对夹具的定位,夹紧力大小完成整个夹具装配图,并对其中典型零件进行拆画,实现了对夹紧运动作出的分析。关键词ZS1105柴油机加工工艺镗床夹具IIAbstractThisarticlemainlyanalysestheprocessplanningofthehousingandthedesignofthespecialfixtureoftheZS1105dieselengine.itanalysestheprocessmethodsandthecuttingremainingparameterinfacesandboreofthehousingandconstitutesthreekindsoftheprocessways.Chosingthelogicaleroneofthem,whichcomputesthetimeration,chosingthecompatibletoolandmachinetooltomaketheaccordingworkingprocedurecards.Inthispaper,forwhichfineboringamongbigholethisprocedurewasdesignedforboringmachine.Contactsizemachinetoolstomapoutplansexpressionfixtureandmachinerelativeposition,drawingprocessingdiagramoftheworkpiecepositioningandboringbarofchoice,thefinalfixtureonthelocation,sizeofclampingforceplanstocompletethefixtureassemblyandsparepartsfordemolitionofatypicalpainting,Andthecampaigntoclampanalysis.KeywordsZS1105dieselengineProcessingTechnologyModularMachinetoolI目录摘要.......................................................................................................................................................IABSTRACT.........................................................................................................................................II1绪论..................................................................................................................................................11.1序言............................................................................................................................................11.2夹具简介....................................................................................................................................11.3本论文主要工作........................................................................................................................22.ZS1105柴油机简介.........................................................................................................................32.1概述.............................................................................................................................................32.2ZS1105柴油机箱体的作用.......................................................................................................32.3ZS1105柴油机箱体的技术分析...............................................................................................33箱体零件工艺设计..........................................................................................................................53.1零件的分析................................................................................................................................53.1.1零件的功用...........................................................................................................................53.1.2零件的结构特点..................................................................................................................53.1.3零件的工艺分析..................................................................................................................63.2工艺规程设计............................................................................................................................73.2.1确定零件生产类型...............................................................................................................73.2.2确定零件毛坯的种类和制造方法.......................................................................................73.2.3工艺方案的制定原则分析..................................................................................................83.2.3.1组合机床概述...................................................................................................................83.2.3.2组合机床工艺方案制定的影响.......................................................................................83.2.4组合机床工艺过程确定的原则..........................................................................................83.2.4.1先面后孔的加工顺序.......................................................................................................83.2.4.2粗精加工分阶段进行.....................................................................................................93.2.4.3工序集中原则...................................................................................................................93.2.5定位基准的选择.................................................................................................................103.2.5.1工艺基准选择的原则及注意的问题.............................................................................103.2.5.2工艺基准的选择原则.....................................................................................................103.2.5.3粗基准的选择.................................................................................................................103.2.5.4精基准的选择...............................................................................................................113.2.6工艺路线的分析.......................................................
