深孔加工专用机床设计说明书.doc

I摘要本文讨论了在现有的加工条件下完成对液压缸套内孔的加工,即深孔加工,提出了车床改造的方案。简单介绍了深孔的发展概况、深孔加工系统的组成、深孔加工系统中的常用装置、深孔加工中的常见问题。至今,深孔加工机床甚少,普通车床不具有加工深孔的功能,因此,将普通车床C6201改装为深孔加工机床,具有深远的意义。关键词深孔加工车床改装进给机构钻削IIAbstractThisarticlediscussedintheexistingprocessingconditionsofhydrauliccylinderlinercompletedintheholeprocessing,namelythedeepholeprocessing,putsforwardthelathereformingscheme.Brieflyintroducesthegeneralsituationofthedeephole,deepholeprocessingsystemcomposition,deepholeprocessingsystemofcommondevice,deepholeprocessingofcommonproblem.Sofar,thedeepholeprocessingmachinetoollittle,ordinarylathedonthavethefunctionofthedeepholeprocessing,therefore,theordinarylatheC6201modifiedforthedeepholeprocessingmachinetoolsandhasfarreachingsignificance.KeywordsthedeepholeprocessinglathetransformationfeedmechanismdrillingIII目录摘要............................................................................................................................................IAbstract.........................................................................................................................................I目录..........................................................................................................................................IIICONTENTS..................................................................................................................................V第1章绪论..................................................................................................................................11.1深孔加工机床的研究意义..............................................................................................11.2国内外发展状况和趋势..................................................................................................11.3深孔加工技术研究概述..................................................................................................31.3.1深孔的定义...........................................................................................................31.3.2深孔加工的类型、特点及要解决的主要问题...................................................41.3.3常用深孔加工系统...............................................................................................61.3.4深孔加工方法及机理的研究...............................................................................71.3.5深孔加工刀具的研究...........................................................................................91.4深孔的镗滚压加工..........................................................................................................91.4.1深孔镗削加工.......................................................................................................91.4.2深孔滚压加工.....................................................................................................11第2章深孔加工机床总体设计的理论分析..........................................................................142.1工艺方案和工艺路线的制定.....................................................................................142.2总体设计.....................................................................................................................152.2.1总体设计内容.....................................................................................................152.2.2深孔加工要求.....................................................................................................162.2.3车床设计总体方案.............................................................................................17第3章深孔加工工装设计......................................................................................................193.1机床主要部件的功能..................................................................................................193.1.1床身.....................................................................................................................193.1.2主轴箱.................................................................................................................193.1.3前、后受油器.....................................................................................................193.1.4前、后拖板.........................................................................................................203.1.5冷却排削系统.....................................................................................................20IV3.2机床设计分析与计算..................................................................................................203.2.1车床型号的选择.................................................................................................203.2.2主要设计参数和技术要求.................................................................................213.2.3钻削力,钻削功率的计算.................................................................................21第4章定位、夹紧装置设计....................................................................................................224.1总体方案设计...............................................................................................................224.2夹紧装置设计...............................................................................................................224.2.1夹瓦强度校核.................................................
