1宁XX大学毕业设计论文半轴套管面钻孔专用机床设计所在学院专业班级姓名学号指导老师年月日2摘要组合机床组合机床是以通用部件为基础,配以按工件特定形状和加工工艺设计的专用部件和夹具,组成的半自动或自动专用机床。加工时,工件一般不旋转,由刀具的旋转运动和刀具与工件的相对进给运动,来实现钻孔、扩孔、锪孔、铰孔、镗孔、铣削平面、切削内外螺纹以及加工外圆和端面等。有的组合机床采用车削头夹持工件使之旋转,由刀具作进给运动,也可实现某些回转体类零件如飞轮、汽车后桥半轴等的外圆和端面加工。本文对半轴套管孔的加工工艺进行了详细的分析,就其孔的加工提出了一次装夹,多工位加工,达到产品图样的精度要求的思路。根据这一思路设计了钻孔组合机床设计。该组合机床由立柱、立柱底座、中间底座、液压滑台、动力箱、多轴箱等组成。本文对各部分的设计进行了详细的计算和论证。关键词组合机床,多轴箱,主轴箱,夹具3AbstractCombinationofmachinetoolsisbasedoncommoncomponents,accordingtotheworkpiecewithaspecificshapeanddesignoftheprocessingcomponentsandspecialfixture,thecompositionsemiautomaticorautomaticspecialmachine.Processing,workpiecegenerallydoesnotrotate,bymovementoftherotatablecutterandtoolandworkpiecerelativefeedmovement,toachievethedrilling,reaming,counterboring,reaming,boring,milling,cuttingandprocessingofexternalthreadfaceandetc..Somecombinationmachineadoptsclampingworkpiecemachiningheadtorotate,bythetoolforthefeedmovement,alsocanachievesomerotatingpartssuchascarrearaxleflywheel,etc.ofthefaceandprocessing.Thehalfshaftbushingholemachiningprocesswasanalyzedindetail,itsholeontheprocessingofafixture,multisiteprocessing,productdesigntoachievetherequiredaccuracytrainofthought.Accordingtothisdesigndrillholemodularmachinetooldesign.Thecombinationofmachinetoolsbyacolumn,columnbase,intermediatebase,hydraulicslipway,thepowerbox,box.Inthispaper,onthepartofthedesignofthedetailedcalculationandverification.Keywordsmodularmachinetool,spindle,spindlebox,fixture4目录摘要..........................................................................................................................................2Abstract.........................................................................................................................................3目录..........................................................................................................................................41绪论.........................................................................................................................................61.1组合机床的国内、外现状................................................................................................61.1.1国内组合机床现状..............................................................................................61.1.2国外组合机床现状..............................................................................................71.2机床设计的目的、内容、要求.......................................................................................81.2.1设计的目的.................................................................................................................81.2.2设计内容..............................................................................................................81.2.3设计要求..............................................................................................................91.2.4机床的设计步骤..........................................................................................................91)调查研究.................................................................................................................92)拟定方案.................................................................................................................93)工作图设计..............................................................................................................92组合机床的总体设计..............................................................................................................102.1组合机床方案的制定....................................................................................................102.1.1制定工艺方案.....................................................................................................102.1.2确定组合机床的配置形式和结构方案。..............................................................102.2确定切削用量及选择刀具.............................................................................................122.2.1确定工序间余量.................................................................................................122.2.2选择切削用量.....................................................................................................122.2.3确定切削力、切削扭矩、切削功率.....................................................................132.2.4选择刀具结构.....................................................................................................142.3钻孔组合机床总设计三图一卡的编制....................................................................142.3.1被加工零件工序图..............................................................................................142.3.2加工示意图........................................................................................................152.3.3机床联系尺寸图.................................................................................................192.3.4生产率计算卡.....................................................................................................212.4多轴箱的设计..............................................................................................................232.4.1绘制多轴箱设计原始依据图.........................................................
