减速箱体机械加工工艺及夹具设计学生姓名：mxl_c学生学号：院（系）：年级专业：指导教师：二〇〇八年六月）摘要摘要箱体零件是一种典型零件，其加工工艺规程和工装设计具有典型性。该箱体零件结构复杂，零件毛坯采用铸造成形。在加工过程中，采用先面后孔的加工路线，以保证工件的定位基准统一、准确。为了消除切削力、夹紧力、切削热和因粗加工所造成的内应力对加工精度的影响，整个工艺过程分为粗、精两个阶段。通过被加工零件的分析完成了机械加工工艺的设计及各加工工序机动时间的计算根据箱体零件的结构及其功能，运用定位夹紧的知识完成了夹具设计。关键词箱体，工艺，夹具I攀枝花学院本科毕业设计(论文)ABSTRACTABSTRACTThisboxmachineelementistypical,themanufacturingprocessandtoolingdesignofitistypical.Thestructureofthisboxmachineelementiscomplicated,themachineelement’sblankadoptcastingshape.Intheprocessofmanufacture,inordertoensureth-elocationdatumaccurateandunity,Iadoptthemanufacturinglinefromfacetohole.Inordertoclearawaytheinfluenceformachiningaccurateofinternalstress,cuttingforce,clampingforce,heatincuttingfromcoarsemanufacturing,thewholemanufacturingpro-cessismadeofcoarseandaccuratemanufacturing.Partswereprocessedthroughthea-nalysisofthecompletemachiningprocessdesignandthemanufacturingprocessesformobiletimecalculations.Accordingtotheboxcomponentsandthefunctionandstructu-re,theuseoftheknowledgepositioningclampcompletedthefixturedesign.KeywordsBoxmachine，Processing，JigII攀枝花学院本科毕业设计（论文）目录目录摘要...............................................................................................................................IABSTRACT...................................................................................................................II1绪论...............................................................................................................................11.1课题背景...............................................................................................................11.2制订工艺规程的意义与作用及其基本要求..............................................................11.3夹具的设计............................................................................................................12零件的分析...................................................................................................................22.1箱体零件的功用和结构特点...................................................................................22.2箱体零件图样分析.................................................................................................22.3箱体零件工艺分析.................................................................................................32.4箱体零件的主要技术要求.......................................................................................42.5主要设计内容........................................................................................................53工艺规程设计...............................................................................................................73.1箱体的材料及毛坯.................................................................................................73.2减速箱箱体加工的主要问题和加工工艺过程设计所应采取的相应措施....................83.3减速箱体加工定位基准的选择................................................................................83.4制定箱体的工艺路线.........................................
