西安文理学院机械电子工程系本科毕业设计（论文）题目立式钻床钻模设计专业班级08机械2班学号08102080232学生姓名刘畅指导教师赵竹青设计所在单位西安文理学院2012年5月立式钻床钻模设计摘要针对套类零件径向孔的加工，设计出立式钻床专用钻夹具。零件为圆周径向均布等直径孔的套类零件，批量生产，主要问题是保证孔之间的位置精度很困难，用划线找正的方法费时费事，且还不易保证孔之间的位置精度，本钻夹具设计旨在能较易保证孔之间的位置精度，提高生产效率。本钻夹具设计重点为选择夹具类型，正确选择和设计钻套及钻模板的结构形式。圆周径向均布等直径孔的套类零件在机械加工生产中应用广泛，设计成熟合理，而此转位钻模正是为加工该零件而设计的专用夹具，有很好的发展前景。应用此转模至少提高工效4倍左右,定能极大地提高劳动生产率、降低操作工人的劳动强度,减小钻头的损耗,.更能延长刀具的使用寿命。关键词均布径向孔钻夹具钻套钻模板分度装置ThedesignofverticaldrillingmachinedrillmoldAbstractAccordingtothesleevepartsinradialholeprocessing,Idesignedtheverticaldrillingmachinefordrillingjig.Partsforthecircumferenceradiallyuniformdiameterholesleeveparts,massproduction,themainproblemisthatbetweentheholepositionaccuracyisverydifficult,scribingalignmentmethodtakestimeandeffort,andisnoteasytoguaranteetheholepositionaccuracybetweenthedrillingfixturedesign,tocaneasilyguaranteetheholepositionaccuracybetween,improveproductionefficiency.Thedrilljigdesignfocusonchoicethefixturetype,makecorrectchoiceanddesignthedrillsleeveandthedrilltemplatestructure.Circularradialuniformetcdiameterholeofsetofcomponentsinproductioninmechanicalprocessingapplications,designmature,buttheinversionreasonableforprocessingthedrillmodeisdesignedspecialfixtureofparts,haveverygoodprospectsfordevelopment.Applicationofthistransfermode4timesatleastimproveworkingefficiency,setaboutwouldgreatlyimprovelaborproductivity,loweroperatinglaborintensity,andreducetheloss,Drillmoreservicelifeofcuttercanextend.KeywordsUniformRadialholeDrillfixtureDrillingsheathDrilltemplate目录第1页目录第一章绪论...........................................................11.1选题背景及目的意义.............................................11.2发展前景.......................................................11.3主要研究方向及内容.............................................2第二章钻床夹具设计原理与说明.........................................32.1机床夹具设计的基本要求和步骤...................................32.2机床夹具的分类和组成...........................................42.3工件在夹具中的定位原理、常见定位方式及定位元件.................52.3.1工件定位原理..............................................52.3.2常见定位方式及定位元件...................................52.4工件在夹具中的夹紧原理.........................................62.5钻夹具设计要点.................................................62.5.1钻模类型的选择...........................................62.5.2钻套类型的选择和设计.....................................72.5.3钻模板的类型和设计......................................10第三章钻夹具设计...................................................123.1研究零件图，进行结构技术分析..................................123.2钻模类型确定..................................................133.3夹具草图构思..................................................143.4工件定位方案确定..............................................143.5工件定位误差分析..............................................16第四章分度装置设计..................................................174.1回转分度装置的组成............................................174.2分度对定机构及操纵机构的设计..................................174.2.1分度方案对比............................................174.2.2对定机构设计............................................174.2.3分度操纵机构设计........................................174.3分度盘锁紧机构的设计..........................................19第五章工件夹紧装置的设计............................................215.1工件夹紧方案..................................................215.2夹紧力确定....................................................215.3工件夹紧装置结构设计..........................................23目录第2页第六章钻套及钻模板的设计............................................246.1钻套的设计....................................................246.2钻模板的类型和设计............................................25第七章钻夹具总体方案................................................267.1夹具体的技术要求..............................................267.2主要零件的材料选择及热处理....................................267.3机床夹具的总装配..............................................277.4夹具使用说明..................................................28结束语...............................................................29致谢.................................................................30参考文献.............................................................31附录..................................................错误未定义书签。
