学院毕业设计论文分度台机械加工工艺及夹具设计所在学院专业班级姓名学号指导老师年月日摘要分度台零件加工工艺及钻床夹具设计是包括零件加工的工艺设计、工序设计以及专用夹具的设计三部分。在工艺设计中要首先对零件进行分析，了解零件的工艺再设计出毛坯的结构，并选择好零件的加工基准，设计出零件的工艺路线；接着对零件各个工步的工序进行尺寸计算，关键是决定出各个工序的工艺装备及切削用量；然后进行专用夹具的设计，选择设计出夹具的各个组成部件，如定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件；计算出夹具定位时产生的定位误差，分析夹具结构的合理性与不足之处，并在以后设计中注意改进。关键词：工艺，工序，切削用量，夹紧，定位，误差全套设计加197216396或401339828AbstractThefixturedesignofacertaintypeofmotorarmaturebracketpartsprocessinganddrillingmachineisdesignprocessdesign,includingthepartsprocessingprocessdesignandthethreepartspecialfixture.Intheprocessofdesignshouldfirstofallpartstoanalyze,understandpartsoftheprocessandthendesignablankstructure,andchoosethegoodpartsofthemachiningdatum,designstheprocessroutesoftheparts;thenthepartseachstepprocessdimensioncalculation,thekeyistodeterminetheprocessequipmentandcuttingtheamountofeachworkingproceduredesign;thenaspecialfixture,fixtureforthevariouscomponentsofadesign,suchastheconnectingpartpositioningdevice,clampingelement,aguideelement,clampandthemachinetoolandothercomponents;thepositioningerrorcausedcalculatefixturewhenpositioning,analysisoftherationalityanddeficiencyoffixturestructure,payattentiontoimprovingandwilldesignin.Keywords:process,process,cutting,clamping,positioning,目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc419315995"摘要PAGEREF_Toc419315995\hIIHYPERLINK\l"_Toc419315996"AbstractPAGEREF_Toc419315996\hIIIHYPERLINK\l"_Toc419315997"目录PAGEREF_Toc419315997\hIVHYPERLINK\l"_Toc419315998"第1章序言PAGEREF_Toc419315998\h1HYPERLINK\l"_Toc419315999"第2章零件的分析PAGEREF_Toc419315999\h2HYPERLINK\l"_Toc419316000"2.1零件的形状PAGEREF_Toc419316000\h2HYPERLINK\l"_Toc419316001"2.2零件的工艺分析PAGEREF_Toc419316001\h3HYPERLINK\l"_Toc419316002"第3章工艺规程设计PAGEREF_Toc419316002\h4HYPERLINK\l"_Toc419316003"3.1确定毛坯的制造形式PAGEREF_Toc419316003\h4HYPERLINK\l"_Toc419316004"3.2基面的选择PAGEREF_Toc419316004\h4HYPERLINK\l"_Toc419316005"3.3制定工艺路线PAGEREF_Toc419316005\h5HYPERLIN
