六档箱体双面攻丝机床左主轴箱设计说明书[带图纸].doc

六档箱体双面攻丝机床左主轴箱设计摘要组合机床是一种专用机床，它是由系列化标准化的通用部件和按被加工零件的形状及加工工艺要求设计的专用部件组成。组合机床随着生产力的发展，是由万能机床和专用机床发展而来的。此次设计的目的就是设计一台攻丝组合机床，用于加工六挡箱侧支架的12个孔。任务是六挡箱双面攻丝机床左主轴箱的设计。这次设计的内容有组合机床“三图一卡”，组合机床的简要设计，主轴箱设计及其液压系统设计，选择出机床总体及各部件的主要参数，画出液压系统图。主轴箱的设计是这次任务的重点，它是组合机床的重要部件之一。它是由通用部件，按照被加工零件的加工要求，根据专用要求设计的。合理的安排每一根轴的的位置，选择合适的各级传动比，将动力和运动由电机或动力部件传给各工作主轴,使之得到要求的转速和转向从而实现对零件的加工。其次，合理安排各主轴和传动轴上齿轮所在的排数；合理布置进油口、放油螺栓、分油盘及油管的位置；确定主轴和传动轴的支撑方式和预紧方法也是非常重要的工作。本文依据主轴箱的设计原则完成了对结构型式的选择及动力计算，传动系统的设计与计算，主轴箱总图设计,主轴箱坐标计算和液压部分的设计。关键词：组合机床，主轴箱，传动轴，攻丝，齿轮DESIGNOFVERTICALHEADSTOCKUSEDINTHEDRILLINGOFSIDESUPPORTABSTRACTThemodularmachine-toolisonekindofspecialpurposemachine.Itiscomposedbythegeneralpartandthespecial-purposepart.Thegeneralpartsaredesignedaccordingtotheserializedstandardizationdesign.Thespecial-purposepartisaccordingtothemachinedandtheprocessingtechnologicalrequirement.Themodularmachine-toolisalongwiththeproductiveforcesdevelopment.Itcomesbythegeneralpurposemachineandthespecialpurposemachinedevelopment.Theaimofourcurrentdesignistodesignaaggregatedrillmachinetool,whichisusedforprocessingthe12holesinthestentoftractor.Thetaskisthedesignofverticalheadstock.Thisdesigninvolvesthecontentthatincludingtheaggregatemachine-toolsathreechartscard、thedesigningofverticalheadstockanditshydraulicsystem、thebriefdesigningofaggregatemachine-tool、choosingtheoverallenginebedandvariouspartsmainparameteranddrawingthehydraulicscheme.Thekeypointofpresentdesignistheverticalheadstockdesigning.Theheadstockisonemajorcomponentsofaggregatemachine-tool.Itisdesignedbyaccordingtothespecial-purposerequest.Itiscomposedbythegeneralpart.Itactsaccordingtowhichisprocessedthecomponentstheprocessingrequest.Itreasonablyarrangeseachthepositionofaxis.Thealllevelsofvelocityratiosischoosingsuitably.Thepowerandthemovementbequeathedbyittotheelectricalmachineryorthepowerparteachworkmainaxle.Itenableeachworkmainaxletoobtaintherequesttherotationalspeedandchangesthusrealizestothecomponentsprocessing.And,reasonablyarrangingrowsbetweenthemainshaftandtransmissiongear；reasonablyarrangingthepositionofoilimport,oil-site,vitta,andoilbolt；determiningthesupportwayandpreloadmethodsbetweentheprincipalaxisandtransmissionshaft.Itsalsomymaintask.Thisarticlehascompletedinlinewiththeheadstockprincipleofdesigntothestructurepatternchoiceandthepowercomputation。Transmissionsystemdesigningandcomputation、multi-spindleboxassemblydrawingdesigningandpartialhydraulicpressuredesigninghydraulicpressurepartialdesigns.KEYWORDS：aggregatemachine-tool,headstock,drivingshaft，vertical，gear目录前言.1第1章组合机床概述.21.1组合机床简介.21.2组合机床的特点.21.3组合机床工艺范围及发展方向.41.3.1组合机床工艺范围.41.3.2组合机床发展方向.4第2章被加工零件工艺方案的制定.62.1零件分析.62.1.1零件的用途.62.1.2零件的技术要求.62.2工艺方案的制定.72.3组合机床切削量及切削力的确定.82.3.1组合机床切削量的确定.82.3.2组合机床切削力的确定.82.4主轴直径的确定和主轴箱所需动力计算.92.4.1主轴直径的确定.92.4.2动力箱的选用.9第3章侧支架立式主轴箱的设计.113.1主轴箱的基本机构及表达方法.113.1.1主轴箱简介.113.1.2通用主轴箱的组成.113.1.3通用主轴箱的通用零件.113.2绘制主轴箱设计原
