镇江市高等专科学校毕业设计（论文）摘要摘要成品取出夹子零件零件加工工艺及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AbstractAbstractpartsprocessingtechnologyandfixturedesignisthedesignoftheprocessdesign,includingthepartsprocessingprocessdesignandthethreepartspecialfixture.Intheprocessofdesignshouldfirstofallpartstoanalyze,understandpartsoftheprocessandthendesignablankstructure,andchoosethegoodpartsmachiningdatum,designstheprocessroutesoftheparts;thenthepartsofeachstepprocessdimensioncalculation,thekeyistodeterminetheprocessequipmentandcuttingtheamountofeachworkingprocedure;designthenaspecialfixture,fixtureforthevariouscomponentsofthedesign,suchastheconnectingpartpositioningdevice,clampingdevice,aguideelement,clampandthemachinetoolandothercomponents;thepositioningerrorgeneratedwhencalculatefixturepositioning,analysisoftherationalityanddeficiencyoffixturestructure,payattentiontoimprovingandwilldesignin.Keywords:Technology,process,cutting,clamping,positioning全套设计加197216396或401339828目录目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc415607909"摘要PAGEREF_Toc415607909\hIIHYPERLINK\l"_Toc415607910"AbstractPAGEREF_Toc415607910\hIIHYPERLINK\l"_Toc415607911"第1章绪论PAGEREF_Toc415607911\h1HYPERLINK\l"_Toc415607912"第2章零件的分析PAGEREF_Toc415607912\h2HYPERLINK\l"_Toc415607913"2.1零件的形状PAGEREF_Toc415607913\h2HYPERLINK\l"_Toc415607914"2.2零件的工艺分析PAGEREF_Toc415607914\h2HYPERLINK\l"_Toc415607915"第3章工艺规程设计PAGEREF_Toc415607915\h4HYPERLINK\l"_Toc415607916"3.1确定毛坯的制造形式PAGEREF_Toc415607916\h4HYPERLINK\l"_Toc415607917"3.2基面的选择PAGEREF_Toc415607917\h4HYPERLINK\l"_Toc415607918"3.3制定工艺路线PAGEREF_Toc415607918\h4HYPERLINK\l"_Toc415607919"3.3.1工艺路线方案一PAGEREF_Toc415607919\h4HYPERLINK\l"_Toc415607920"3.3.2工艺路线方案二PAGEREF_Toc415607920\h
