无摘要零件的工艺编制,在机械加工中占有非常重要的地位,零件工艺编制得合不合理,这直接关系到零件最终能否达到质量要求;夹具大的设计也是不可缺少的一部分,它关系到能否提高其加工效率的问题。因此这两者在机械加工行业中是至关重要的环节。这次毕业设计,我设计的课题是一级减速器箱体加工工艺及夹具设计。该箱体零件结构较复杂,体积较大。为了提高生产效率和降低劳动强度,我设计了一款钻床夹具。本次设计说明书分为三个部分:第一部分分为机械加工工艺规程的慨述,其中有工艺的组成,工艺规程的内容和作用,机械制造工艺规程的类型及格式,工艺规程的原理和步骤的介绍。同时对定位基准的选择,工艺路线中表面加工方法的选择、加工方法的划分、加工顺序的安排起到详细的介绍。第二部分分为机床夹具的设计,讲解机床夹具的慨述,机床夹具的组成分类。工件定位的原理,定位方法和定位元件对定位误差的计算,对夹紧装置的组成和夹紧力的三要素作了分析。在这次工艺中表面在铣床上加工;直径为40mm以上的在镗床上加工;其余的孔因分部面多我专门设计了一款夹具便于在钻床上加工(有图)。第三部分主要介绍对零件加工的全过程,我这次设计主要选的是铸件对毛坯的确定;加工中的时效性处理;工艺路线的编制和工序卡片的编写(有卡片工艺、工序全过程)在加工完后的检验。在加工中夹具的设计和计算,对机械简明手册的翻阅对国标对准。在加工完后绘制出了完美的零件图(A0号)。在经济时效下保证了加工满足的要求。关键词:箱体、工艺、工序、夹具、绘制零件图图无英文摘要ThePartoftheprocess,inmachiningplaysaveryimportantpartoftheprocess,preparetoreasonableorunreasonable,itdirectlyrelatestothequalityrequirementscouldeventuallyparts,Thedesignoffixtureisbig,itistheindispensablepartinrelationtoimprovetheefficiencyofthemachining.Sobothinmechanicalprocessingindustryiscruciallink.Thegraduationdesign,thetopicisIdesignprocessandfixtureenclosurereducerdesign.Thiscaseiscomplex,volumepartsstructure.Inordertoimproveproductionefficiencyandreducelaborintensity,Idesignadrillfixture.Thedesignmanualisdividedintothreeparts:Thefirstpartisdividedintothemachiningprocessofthespecifiedprocedures,includingprocess,contentsandprocedure,mechanicalmanufacturingprocessplanningofthetypeandtheprocedureformats,introducedtheprincipleandprocedure.Thechoiceofthelocatingdatum,theprocessrouteintheselectionofsurfacemachiningmethod,themethodofprocessing,sequencearrangementhasbeenintroducedindetail.Thesecondpartofthemachinetool'sfixturedesign,theinterpretationofthemachinetool'sfixtureofthemachinetool'sfixturesoup,compositionandclassification.Theprinciple,workpiecepositionandorientationofthepositioningerrorcalculationofcomponentsforclampingdevice,thecompositionandclampingforceofthreefactorsareanalyzed.Intheprocessofsurfaceinmillingmachining,Diameter40mminformoreboring,TherestoftheholefordivisionIfaceafixturedesignedtofacilitatetheprocessing(inpress).Thethirdpartmainlyintroducestheprocessofpartsprocessing,Ichoosethedesignismainlyfordeterminationofcastingbillet,Thetimeliness,Thepreparationprocessrouteandtheprocessofwriting(card),wholeprocesscardtechnologyinprocessingafterinspection.Intheprocessofcalculation,andfixturedesignofmechanicalconcisemanualofgbthroughalignment.Inprocessingaftermappedtheperfectpartsgraph(A0).Underthelimitationintheeconomicguaranteeprocessingrequest.Keywords:process,process,anddrawingpartsfixture,toto无目录摘要1英文摘要2第一章绪论51.1制造工业的重要性51.2减速器的运用、类型51.3工艺设计的重要性61.4减速器箱体设计工艺的重要性7第二章对零件的工艺分析82.1工艺过程的组成82.2工艺规程的内容与作用82.2.1工艺规程是指导生...
