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C620-1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,theordinarylatheC620-1modifiedforthedeepholeprocessingmachinetoolsandhasfar-reachingsignificance.Keywords:thedeepholeprocessing；lathetransformation；feedmechanism；drillingIII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.234.2.2钻杆固定架设计.244.2.3弹簧设计.254.2.4压板设计.274.3授油器的结构设计.28结论.30致谢.31参考文献.32VCONTENTSAbstract.错误!未定义书签。Abstract.错误!未定义书签。CONTENTS.错误!未定义书签。Chapter1Introduction.11.1Thedeepholeprocessingmachinetoolsresearchsignificance.11.2Thedomesticandforeigndevelopmentstatusandtrends.11.3Thedeepholeprocessingtechnologyresearchoverview.31.3.1Definitionofdeephole.31.3.2Commonlyusedthedeepholeprocessingsystem.错误!未定义书签。1.3.3Thedeepholeprocessingcuttingtool.61.3.4Deepholecutfeaturesbore.71.3.5Deepholerollingprocessingcharaceteristics.91.4Deepholeboringandrollingprocessing.91.4.1Deepholeboringprocessing.91.4.2Deepholerollingprocessing.11Chapter2Thedeepholeprocessingmachinetheoveralldesignoftheanalysis.142.1Technicalschemeandtheformulation.142.2Theoveralldesignscheme.152.2.1Generaldesigncontent.152.2.2Deepholeprocessingrequirements.162.2.3Latheoveralldesignscheme.17Chapter3Thedeepholeprocessingequipmentdesign.193.1Thefunctionofthemaincomponentsofthemachinetool.193.1.1Lathebed.1
