ZS1105柴油机箱体制造工艺规程及专用夹具设计(铣)毕业论文.doc

I摘要本课题进行ZS1105柴油机箱体零件精铣端面专用夹具设计,主要内容分为首先是对箱体零件工艺设计,在分析了ZS1105柴油机箱体的具体结构及技术要求的基础上,详细制定了两种箱体加工整体加工工艺路线,并比较其优劣选择最优的方案进行加工。根据各道工序的技术要求,选定各道工序的背吃刀量、进给量、切削速度以及所采用的机床、刀具、夹具等,确定各道工序的时间定额,从而绘制工艺过程卡片。然后对精铣前后端面专用夹具体进行设计,根据被加工零件的结构特点、加工内容的尺寸和精度要求,确定组合铣床的配置方案,对专机进行总体设计-三图一卡即为零件工序图、加工示意图、机床联系尺寸图和机床生产率计算卡的设计。其次绘制其装配图和相关的零件图。关键词工艺过程组合机床铣床夹具IIAbstractThistopiccarriesondesignwiththecombinedmillingmachineintheZS1105dieseloilengineercasebody,themaincontentdividedintoFirst,aboutboxbodypartsprocessplanning,atthebaseofanalyzingtheZS1105dieseloilengineercasebodysconcretestructureandthetechnologicalspecification.Iformulatedtwokindofboxbodyprocessingprocessrouteindetail,andcomparedthemtochoosethemostsuperiorprocessroutetocarryontheprocessing.Idesignatedthepenetrationofacuttingtool,thefeedquantity,thecuttingvelocityaswellas,thecuttingtool,thejigandsoon,whichdeterminethetimequota,andmaketheprocesscard.Second,aboutmodularmachinetooldesign,accordingtotheuniquefeatureofthecomponents,theprocessingcontentsizeandtheaccuracyrequirement,Ideterminedthatcombinedmillingmachinesdispositionplan,carriedonasystemdesignthreedrawingsandonecardnamelythecomponentsworkingprocedurechart,theprocessingschematicdrawing,thetoolrelationdimensionaldrawingandthetoolproductivitycomputationcarddesign.Third,Idrawledtheassemblydrawingsofhydraulicslideranddetaildrawings.KeywordsTechnologicalprocessModularmachinetoolSpecialmillingfixture徐州工程学院毕业设计I目录1绪论.........................................................................................................................................12ZS1105柴油机简介.................................................................................................................22.1概述.......................................................................................................................................22.2ZS1105柴油机箱体的作用................................................................................................22.3ZS1105柴油机箱体的技术分析........................................................................................23箱体工艺分析与设计.................................................................................................................43.1箱体工艺的分析..................................................................................................................43.2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................................................................................83.2.3工艺路线的制定原则...................................................................................................83.2.4工艺路线的分析..........................................................................................................123.3切削用量和时间定额的确定............................................................................................133.3.1切削用量的选择原则.................................................................................................133.3.2切削用量和时间定额..................................................................................................144组合机床总体设计...................................................................................................................274.1组合机床概述....................................................................................................................274.2制定组合机床工艺方案注意事项.....................................................................................274.2.1组合机床设计应满足的基本要求.............................................................................274.2.2针对零件特点设计组合机床......................................................................................284.3组合机床设计.....................................................................................................................294.3.1概述..............................................................................................................................294.3.2组合机床总体设计......................................................................................................305专用夹具的设计.......................................................................................................................335.1机床夹具的作用................................................................................................................335.2对夹具的要求....................................................................................................................335.3箱体类零件定位基准的选择............................................................................................335.4专用夹具的设计步骤.........................................................................................................345.4.1研究原始资料..............................................................................................................345.4.2确定夹具的结构方案..................................................................................................345.4.3绘制夹
