汽车万向节滑动叉专用夹具设计摘要机床夹具是指在机械加工过程中，为了保证加工精度，固定工件，以接受加工或检测的工艺装备。机床夹具是一种不可缺少的工艺装备，它的设计直接影响加工的精度、劳动生产率和产品的制造成本等，在企业的产品设计制造以及生产技术装备中占有极其重要的地位。只有工件需要大批量生产时，商家才会选用专用夹具。专用夹具的设计，在一定程度上可以解决了现有夹具在工件大批量生产中的问题，从而提高了总体的生产效益。它同其他一般夹具一样包括定位装置、夹紧装置、夹具体。专用夹具的专用性强，操作迅速方便，是针对某一工件某一工序的加工要求而专门设计和制造的机床夹具，专用夹具的使用可以使产品相对稳定、在大批量生产中可以获得较高的精度和生产效率，对工人的技术水平要求相对较低。本文为万向节滑动叉专用夹具的设计。它除了具有一般夹具的特点外，还有装夹简单，定位准确，不要找正，操作容易的特点。特别适合产品质量要求较高的大批量生关键词：机床夹具，定位装置，夹紧装置GimbalslidingforkmachiningproceduresandprocessequipmentABSTRACTMachinefixturemeansthatthemachiningprocess,inordertoensurethattheprocessingaccuracy,fixedworkpiecetoacceptprocessingortestingofequipment.Machinefixtureisanindispensabletechniqueandequipment,itisdesigneddirectlyaffecttheaccuracyofprocessing,laborproductivity,andproductmanufacturingcosts,intheenterpriseproductdesignandmanufacturingaswellasproductiontechnologyandequipmentoccupiesanextremelyimportantposition.Onlywhentheworkpieceneedsofmassproduction,businessmenwillusespecialfixture.Fixtureforthedesign,toacertainextent,theexistingfixturecanbesolvedinthemassproductionoftheworkpiece,thusenhancingtheoverallproductionefficiency.Hegenerallyitwithotherpositioningdevicesincludingthesamefixture,clampingdevices,specificfolders.Fixturefordedicatedstrong,operationquicklyandeasily,isapartofaprocessfortheprocessingrequirementsofthedesignandmanufactureofspecializedmachinefixture,thefixturefortheuseofproductscanberelativelystable,willbeinmassproductioninthehighertheaccuracyandefficiencyofproductionandthelevelofskillsofworkersinrelativelylowdemand.ThisarticlesemiautomaticCylindricalGrinderplacedunderspecialfixturedesign.Inadditiontothecharacteristicsofageneralfixture,butalsoclampingsimple,accuratepositioning,isnottofind,easyoperationcharacteristics.Particularlysuitableforthehigherqualityrequirementsmassproduction.KEYWORDS:machinetooljig，positioningdevice，clamp，spring目录前言.............................................................................................................1第一章零件的分析.....................................................................................41.1零件的作用...................................................................................41.2零件的工艺分析............................................................................7第二章工艺规程设计.................................................................................52.1确定毛配的制造形式...................................................................52.2基面的选择....................................................................................52.3制定工艺路线................................................................................62.3.1工艺路线方案一.................................................................62.3.2工艺路线方案二.................................................................62.3.3工艺方案的比较与分析.....................................................72.4...
