液压缸的加工工艺分析与深孔推镗夹具设计--毕业设计说明书汇编（完整版）资料(可以直接使用，可编辑优秀版资料，欢迎下载）摘要将液压缸提供的液压能重新转换成机械能的装置称为执行元件。执行元件是直接做功者，从能量转换的观点看，它与液压泵的作用是相反的。根据能量转换的形式，执行元件可分为两类三种：液压马达、液压缸、和摆动液压马达，后者也可称摆动液压缸。液压马达是作连续旋转运动并输出转矩的液压执行元件；而液压缸是作往复直线运动并输出力的液压执行元件。液压缸是机器和部件的基础零件，由它将机器和部件中许多零件连接成一个整体，并使之保持正确的相互位置，彼此能协调地运动。保证零件加工质量的前提下，提高生产率，降低成本，是国内外现代机械加工工艺的主要发展方向之一。本文通过对液压缸零件图及结构形式的分析基础上，对液压缸零件进行工艺分析、工艺说明及加工过程仿真和精度分析。同时以此液压缸零件为例进行工艺过程设计，编写相应工艺卡片；其次再对液压缸的孔的加工进行专用夹具设计与精度和误差分析。实践证明，该工艺与夹具结果能满足生产要求。关键词：液压缸加工工艺定位夹具设计AbstractHydrauliccylinderwillbeabletoprovidethehydraulic-mechanicalenergyconversiondevicecalledactuators.Workisadirectimplementationofcomponents,fromthepointofviewofenergyconversion;itistheroleofthehydraulicpumpopposite.Accordingtoenergyconversionintheformofimplementationofthethreecomponentscanbedividedintotwocategories:hydraulicmotors,hydrauliccylinders,hydraulicmotorsandswing,whichmayalsobesaidswinghydrauliccylinder.Hydraulicmotoristhecontinuoustorqueandrotationalmovementofthehydraulicactuators,andhydrauliccylinderisareciprocatinglinearmotionandtheoutputofthehydrauliccomponents.Hydrauliccylinderisthebasisofmachinesandcomponentsparts,whichmakesmanypartsarelinkedintoawhole,andmakeitmaintainthecorrectmutualposition,inacoordinatedmannerwitheachothermovements.Atthepremiseofensurepartsprocessingquality,improveproductivityandreducethecostisoneofthemaindevelopmentdirectioninmodernmachiningtechnologyathomeandabroad.Thisarticlebasedontheanalysisofbodypartsgraphandthestructuretohaveprocessingprocesssimulationandprecisionanalysisaboutthepartsandprocessdescription.Atthesametime,hydrauliccylindertomaketheasanexamplewedesigntheprocessdesign,andmakethecorrespondingprocesscards.Andthentodesignthespecialfixtureforthemachiningtheholeatthesurfaceoftheboxesandanalysestheprecisionandtheerror.Thepracticeprovedthatthisprocessandfixturecansatisfytheproductionrequirements.Keywords：hydrauliccylinder;Processingtechnology;Fixedpos
