芜湖职业技木修浣WuhuInstituteofTechnology毕业设计说明书论文题目典型盘套类零件的机械加工工艺及夹具设计学院____________________________________________专业____________________________________________毕业生学号___________________________________________及姓名___________________________________________指导教师姓名___________________________________________2020年5月摘要本次设计内容涉及了机械制造工艺及机床夹具设计、金属切削机床、公差配合与测量等多方面的知识。盘套加工工艺及其钻孔的夹具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，误差分析ABSTRACTThedesigncontentofthemechanicalmanufacturingtechnologyandmachinetoolfixturedesign,metalcuttingmachinetool,tolerancematchingandmeasurementofaspectsofknowledge.Flangeprocessingandmilling3holesfixtureisincludingpartsprocessingprocessdesign,processdesignandspecialfixturedesignthreeparts.Shouldfirstanalyzethepartsintheprocessdesign,understandpartsoftechnologytodesignthestructureofblank,andchoosethegoodpartsprocessingbenchmark,designprocessoftheparts;Thenthepartssizeofeachworkstepoftheprocess,thekeyistodeterminetheprocessequipmentforeachprocessandcuttingparameter;Forthedesignofspecialfixture,thenselectdesignoutofthecomponentpartsofthefixture,suchasthepositioningdevice,clampingdevice,ledcomponents,specificconnectionwithmachinepartsandotherparts;Calculatedattheexitoffixturelocatingpositionerror,analysistherationalityofthefixturestructureanddeficiency,andpayattentiontotheimprovementinthelaterdesign.Keywords：Thecraft,theworkingprocedure,thecuttingspecifications,clamp,thelocalization,theerrorii目录摘要......................................................................IABSTRACT.......................................................................................................................II第1章零件结构的工艺性分析...............................................11.1零件的结构特点..................
