毕业设计说明书第I页卧式双面23轴组合钻床前主轴箱设计摘要机械制造设备的发展是机械工业最主要的环节,目前,机械加工对精度要求越来越高,机械工厂为了降低加工成本,提高加工质量,致使组合机床在制造业中应用越来越广泛,并已显示出巨大的优势。组合机床主要是保证被加工零件的尺寸精度和位置精度要求,高速高效的完成对缸体的加工。在组合机床的设计中,主轴箱加工工艺是关键。绘制主轴箱设计原始移居图,拟定主轴箱的传动路线,应用最优化方法布置齿轮,确定传动参数,绘制主轴箱装配图、箱体补充加工图。组合机床主轴箱的基础环节是绘制主轴箱树形图,主轴箱树形图实际上是借鉴了通用机床主传动系统设计中使用的转速图、结构图经演化而来。由于主轴箱传动系统是一个原动件带动多个从动件,没有变速机构,而传动路线条数却很多,出现许多分支。从图形上看,驱动轴相当于树根,各主轴及油泵轴均为末端件,相当于各条树枝的末梢,因此形象地命名为“树形图”。关键词:组合机床,主轴箱,“树形图毕业设计说明书第II页Horizontaldouble23shaftcombinationdrillingmachinebeforespindleboxdesignAuthor:LiBeiTutor:JiaBaiHeAbstractMachinerymanufacturingequipmentisthedevelopmentofthemachineryindustrythemostmainlink,atpresent,mechanicalprocessingtotheprecisionrequirementmoreandmorehigh,machineryfactoryinordertolowermanufacturingcosts,improvethemachiningquality,thecombinationmachinetoolsinthemanufacturingindustryismoreandmoreextensiveapplication,andhasshowngreatadvantage.Combinationmachinetoolsismainlybythesizeoftheprocessingcomponentstoensuretheprecisionandlocationaccuracy,highspeedandhighefficienttothefinishofmachining.Inthedesignofthecombinationmachinetools,spindleboxprocessingtechnologyisthekey.Drawspindleboxdesignoriginalmovedtofigure,drawsupthespindleboxtransmissionline,applicationoptimizationmethodsdecorategear,suredriveparametersanddrawthespindlebox,boxaddedprocessingchartassemblydrawings,andaxle,gearsandpartsofintensity.Combinationmachinetoolsspindleboxfoundationlinkisdrawingspindleboxtreestructures,spindleboxtreestructuresisactuallylessonsfromthegeneralmachinemaintransmissionsystemusedinthedesignofthespeeddiagram,thestructureoftheevolution.Duetothespindleboxtransmissionsystemisaformermoveadrivemorefollower,nospeedchanginginstitutions,andtransmissionlinenumberbutmanyarticle,appearmanybranches.Fromgraphics,itisequivalenttotherootsofthedriveshaft,thespindleandoilpumpshaftareattheendofathing,whichisequivalenttothevariousperipheralbranches,sotheimageofthenamedtreestructures.Keywords:transferandunitmachine,Headstock,athreechartscardTrees毕业设计说明书第III页目录1.绪论........................................................................................................................11.1组合机床的特点......................................................................................................11.2组合机床的分类和组成.....................................................................................21.3组合机床的方案选择.............................................................................................31.4课题研究的意义及国内外现状..........................................................................31.5论文构成及研究内容.............................................................................................52.加工工艺分析........................................................................错误!未定义书签。3.多轴箱的基本结构及表达方法............................................错误!未定义书签。3.1多轴箱的组成.....................................................................错误!未定义书签。3.2多轴箱总图绘制方法特点...............................................错误!未定义书签。3.3多轴箱通用零件.................................................................错误!未定义书签。4.多轴箱的设计........................................................................错误!未定义书签。4.1绘制多轴箱设计原始依据图..........................................错误!未定义书签。4.2主轴、齿轮的确定及动力计算......................................错误!未定义书签。4.2.1主轴型式的确定..............................................错误!未定义书签。4.2.2主轴直径的确定...............................................错误!未定义书签。4.2.3齿轮模数的确定...............................................错误!未定义书签。4.2.4多轴箱所需动力的计算..................................错误!未定义书签。4.3多轴箱传动设计.................................................................错误!未定义书签。4.3.1拟定传动路线..................................................错误!未定义书签。4.3.2确定驱动轴、主轴坐标尺寸..........................错误!未定义书签。4.3.3确定传动轴位置及齿轮齿数..........................错误!未定义书签。4.4绘制多轴箱总图及零件图....................................................................................94.4.1多轴箱零件设计..............................................................................94.4.2多轴箱总图设计..............................................................................95.组合机床多箱CAD系统......................................................................................11结论..........................................................................................................................12致谢..........................................................................................................................13毕业设计说明书第IV页参考文献..................................................................................................................14毕业设计说明书第1页1.绪论1.1组合机床的特点组合机床是根据工件加工需要,以大量通用部件为基础,配以少量的专用部件组成的一种高效专用机床。它能够对一种(或多种)零件进行多刀、多面、多工位加工。在组合机床上可以完成钻孔、扩孔、铣削磨削等工序,生产效率高,加工精度稳定。立卧复合多轴攻丝组合机床组合机床与通用机床、其他专用机床比较,具有以下特点:(1)组合机床上的通用部件和标准零件约占全部机床零件、部件总量的70%~80%,因此设计和制造周期短、投资少、经济效果好。(2)由于组合机床采用多刀加工,并且自动化程度高,因此比通用机床生产效率高,产品质量稳定,劳动强度低。(3)组合机床的通用部件是经过周密设计和长期生产实践考验的,又有厂成毕业设计说明书第2页批制造,因此结构稳定、工作可靠、使用和维护方便。(4)在组合机床上加工零件时,由于采用专用夹具、刀具和导向装置等,加工质量靠工艺装备保证,对操作工人水平要求不高。(5)当被加工产品更新时,采用其他类型的专用机床时,其大部分零件要报废。用组合机床时,其通用部件和标准件可以重复利用,不必另行设计和
