数控车床液压尾座设计论文[带图纸].doc

I本科毕业设计(论文)题目数控车床尾座套筒液压装置设计系别机电信息系专业机械设计制造及其自动化班级姓名学号导师2013年4月27日II数控车床尾座套筒液压装置设计摘要为了完成本课题的设计,在设计之前的准备工作必须做好,首先是搜集和分析资料,主要包括国内外数控机床的发展现状液压技术和液压传动系统的基本资料同等机床液压尾座的图纸和资料等。其次是初步确定液压尾座的总体布局,包括配置形式、液压系统的布置及选择液压能源及相应的配套元件等。最后主要是关于尾座的设计计算。数控机床变档卡紧及尾座顶紧的控制方式基本上是手工控制,在通常的加工过程中,需先用手工控制的方式完成变档和卡紧工作,然后再进行装夹,在装夹完毕后还需要使用手工控制的方式完成尾座的顶紧工作。由此可知,在数控机床的加工作效率效率并不高,而且工人劳动强度大,耗时又耗力,还会增加企业成本。因此,本课题研究所要达到的预期效果是在数控车床加工过程中,当需要使用尾座时,使用本课题所设计的尾座可以提高加工过程的机械化和自动化水平,提高生产效率,降低工人的劳动强度,降低企业成本。关键词数控机床尾座液压系统液压缸IIThedesignofCNCmachineTailstockHydraulicsystemAbstractToaccomplishthisdesign,Icollectedandanalysedtheinformationbeforethedesign,includingdomesticandinternationaldevelopmentofCNCmachinetoolshydraulicsystemofhydraulictechnologyandthebasicinformationequalhydraulicmachineTailstockthedrawingsandinformation.ThenistentativelydeterminedtheoveralllayoutofhydraulicTailstock,includingtheallocationofform,layoutandthehydraulicsystemofhydraulicenergy,andselecttheappropriatematchingcomponents,suchas.ThiswasfollowedbythemainTailstockthedesignandcalculation.CNCmachinetoolschangedfilecardsbearandTailstocktoptightisbasicallymanualcontrol,intheconventionalprocess,thechangerequiredmanualcardfileandclampingatightandthenagainafterthefixturealsoneedtouseamanualTailstockThetoptight.Therefore,intheprocessofCNCmachinetoolsinefficiencyisnothigh,workersinlaborintensityandgreat.Therefore,theissueoftheInstitutetoachievethedesiredresultsintheCNClatheprocessing,whentheneedtouseTailstock,theuseofthisissuebytheTailstockdesigncanimprovetheprocessofmechanizationandautomationlevel,increaseproductionefficiencyandreduceWorkersinthelaborintensity.KeywordsNumericallycontrolledmachineTailstockHydraulicsystemHydrauliccylinderinsidediameterIII目录1绪论.........................................................................................................................................11.1研究背景和意义...............................................................................................................11.2液压传动介绍...................................................................................................................11.3国内外数控机床的发展现状...........................................................................................21.3.1国外数控机床发展现状.........................................................................................21.3.2国内数控机床发展现状.........................................................................................31.4本文研究对象...................................................................................................................42液压尾座液压传动总体设计............................................................................................52.1尾座简介...........................................................................................................................52.2回路设计...........................................................................................................................52.2.1液压尾座顶针液压回路.........................................................................................62.2.2液压尾座顶针夹紧液压回路.................................................................................73尾座部分的设计...................................................................................................................93.1液压系统压力...................................................................................................................93.2顶针油缸的计算...............................................................................................................93.2.1顶针轴向力..............................................................................................................93.2.2液压油缸计算........................................................................................................103.3液压泵的设计.................................................................................................................123.3.1液压泵工作压力的确定........................................................................................133.3.2液压泵流量的确定...................................................................错误未定义书签。3.3.3电动机功率的确定...................................................................错误未定义书签。3.4液压元件的选择.............................................................................................................163.4.1油管及管接头........................................................................................................163.4.2过滤器的选择........................................................................................................163.4.3油箱的选择............................................................................................................173.4.4油箱容积的确定....................................................................................................173.5液压系统的性能验算...................................................................................................183.5.1液压系统压力损失计算........................................................................................183.5.2液压系统发热温升的验算.............................................................
