002017届本科生毕业论文题目：CA6140车床主轴箱的设计院（系）：信息工程学院专业班级：机械1304班学生姓名：焦尚指导教师（职称）：何国荣（副教授）提交时间：二〇一七年五月摘要在工业生产的很多时候都要用到CA6140车床，然而，这种车床的自动化程度不高，结构又相对复杂，如果要加工一些相对复杂的工件，就需要不断换刀，给实际操作带来很多麻烦，再加上这种车床的加工过程较慢，造成效率不高，所以，只能在单件或者小批量生产中广泛应用。本文主要对该机床的主轴箱进行了设计，采用三轴支撑的滚动轴承，加上双轴滑移的共用齿轮作为进给体系；加上快速电机和十字手柄，极大改善了机床的性能，提高了操作性。本文从CA6140机床的参数设定、传动体系图制定、传动方案制定，主要零部件的校荷，对该机床的主轴箱设计进行了说明，并附有机床了零部件整体装配详图。关键词：CA6140机床；主轴箱；零件；传动；AbstractThescopeofapplicationofCA6140latheisveryextensive,butthecomplexstructureandlowdegreeofautomation,theworkpieceprocessingismorecomplicatedinshape,changetheknifetrouble,intheprocessofauxiliarytimeisrelativelylong,lowproductivity,suitableforsingleorsmallbatchproduction.Themainshaftthreesupportadoptstherollingbearing;thefeedsystemusesthetwoaxleslidingcommongearmechanism;thelongitudinalandtransversefeediscontrolledbythecrosshandle.Themachinehasgoodrigidity,largepowerandconvenientoperation.Asamajorturningprocessingmachine,CA6140machineiswidelyusedinmechanicalprocessingindustry,thedesignofthemainspindleboxforCA6140machinedesign,designisthemaincontentofthemainparametersofthemachine,drawingupthetransmissionplanandthetransmissionscheme,themainpartsofthecalculationandchecking,theuseofCADdrawingsoftwaredesignandprocessingofparts.Keywords:CA6140machinetool；spindlebox；parts；transmission目录第1章引言........................................................5第2章主要技术参数................................................6第3章传动方案和传动系统图的拟定..................................83.1.主运动传动链..............................................83.2.进给传动链...............................................11第4章主要设计零件的计算和验算...................................15..............................................................15..............................................................17...........................................................17...........................................................19...........................................................21...........................................................24...........................................................26Ⅱ轴及轴上零件设计............................................27...........................................................27...........................................................31...........................................................324.4传动系统的Ⅲ轴及轴上零件设计..............................34...........................................................344.4.2传动轴的验算.........................................384.4.3轴组件的刚度验算.....................................40Ⅳ轴及轴上零件设计............................................42...........................................................42...........................................................45...........................................................484.6.传动系统的Ⅴ轴及轴上零件设计.............................50..............................................................
