题目：回转体的加工工艺与夹具设计摘要本课题是对现有成套的角铁类车床夹具设计进行分析，以便能够解决这一类夹具的设计问题。分别用CAD和SOLIDWORKS画出本套夹具的平面图和三维图。为了解决角铁类夹具的设计问题，本课题主要通过三类车床夹具进行分析。分别是，壳体零件镗孔车端面夹具，镗脱落蜗杆支架孔车床夹具，横拉杆接头内孔车夹具，以及所给零件的工艺分析，计算、编写各工件加工工艺；各工件的定位分析（自由度）；夹具夹紧力的分析与计算；各夹具的三维零件设计、三维装配；夹具三维仿真等。本课题根据车床夹具的特点，针对具体的回转体工件进行一系列的设计。关键词：回转体车床夹具仿真Workpieces,anditsangleironoftherotarylathefixture3DdesignandsimulationAbstractThistopicistheanalysisandappraisalofexistingsetsofangleironclasslathefixturedesign,Inordertobeabletosolvetheproblemsofthistypeoffixturedesign.Fixtureinthissetoffloorplansand3DCADandSOLIDWORKSdraw.Inordertosolvetheproblemofangleironfixturedesign,Themainsubjectofthreetypesoflathefixture.Theyare,Shellpartsboringcarendfixture,Boringoffthewormbracketholelathefixture,Tierodconnectorholecarfixture,Aswellastopartsoftheprocess,Calculatedtowriteeachworkpieceprocessing;workpiecepositioning(DOF),thefixturepositioningerrorcalculation;analysisandcalculationofthefixtureclampingforce;3Dpartdesignofthefixture,three-dimensionalassembly;fixturesdimensionalsimulation;fixturedrawingsgeneration.Thesubjectaccordingtothecharacteristicsofthelathefixture,Aseriesofdesignforaspecificrotaryworkpiece.Keywords:rotarylathefixturesimulation主要符号表主要符号表a背吃刀量mmpf每转进给量mmK修正系数pK安全系数M扭矩F切削力工件与压板间的圆周方向摩擦因数。1工件与V型块间的圆周方向摩擦因数。2工件与压板间的轴向摩擦因数。3工件与V型块间的轴向摩擦因数。4d内孔直径D外圆直径摩擦因数F夹紧力(N)JF作用力(N)QL作用力臂(mm)d螺杆直径0α螺纹升角螺纹处摩擦角.1螺杆端部与工件间的摩擦角.2螺杆端部与工件间的当量摩擦半径目录摘要...............................................错误！未定义书签。Abstract.....................................................II主要符号表.................................................III1绪论.............................................................11.1课题意义和背景及其夹具的发展趋势.............................11.2国内外的现状和发展状况.......................................11.2.1现代机床夹具的新要求...................................21.2.2现代机床夹具的发展方向.................................21.3夹具的作用及意义.............................................31.3.1夹具的研究意义.........................................31.3.2夹具的作用.............................................31.4本课题研究的难点和重点.......................................31.4.1研究难点31.4.2研究重点41.4.3研究目的42镗脱落蜗杆支架孔车床夹具.........................................52.1零件的设计...................................................52.1.1零件图的绘制...........................................52.1.2零件加工工艺过程.......................................52.1.3本工序工序.............................................72.1.4加工要求72.1.5工序参数72.2零件定位设计.................................................72.2.1基准的选择.............................................72.2.2定位元件设计...........................................82.2.3定位误差分析...........................................92.3夹紧机构设计.................................................92.3.1夹紧方式92.3.2所需夹紧力的...
