洛阳理工学院毕业设计（论文）填料箱盖的加工工艺及专用夹具设计摘要在机械制造的机械加工，检验，装配，焊接和热处理等冷热工艺过程中，使用着大量的夹具，用以安装加工对象，使之占有正确的位置，以保证零件和工件的质量。本次设计主要是进行填料箱盖零件的专用夹具的设计，是对我们以往所学知识的总结和对我们所掌握知识的一次扩展。本文主要从工艺规程的指定与夹具的设计两方面出发。根据零件本身的特点，生产类型以及零件在具体工作时的作用选择工艺规程和夹具。在工艺规程方面：确定生产类型，综合考虑其准确度高，生产效率高，消耗经济少等方面，选择一个最优方案；在夹具设计方面，因为是盖体类零件，加工Ф13.5孔，选择钻床加工，及ø60孔粗糙度的加工，选择立轴矩台磨床加工，考虑诸多因素拟订最优方案，最终完成本次设计。关键词：工艺规程,夹具设计,最优方案PackingboxcoverprocessingandspecialfixturedesignI洛阳理工学院毕业设计（论文）ABSTRACTThemachinemadeinthemachineprocesses,examining,assembling,weldingwithheathandletowaitcoldandhotcraftprocessin,useagreatdealoftongs,inordertothegearingprocessobject,makingitoccupyrightpositiontopromisethequalityofsparepartsandworkpiece.Thisdesignismainlythedesignofappropriationtongswhichcarriesoncoveringbodyspareparts,istallyuptheknowledgethatwelearnbeforeandtotheonceexpandingoftheknowledgethatwecontrol.Thistextmainlysetsoutfromthedesignbothsideofthespecifyingofcraftrulesdistanceandthetongs.Accordingtothecharacteristicsofspareparts,thefunctionproducedtypeandsparepartswhileconcretelyworkingchoicethecraftrulesdistanceandtongs.Inthecraftrulesdistanceaspect:Assuranceproduceatype,comprehensiveconsideritsaccuratedegreehigh,produceanefficiencyishigh,consumeeconomylittleetc.aspect,choosethesuperiorproject;Designaspectinthetongs,becauseofiscoverbodyspareparts,processФ13.5bores,thechoicedrillsabedtoprocess,consideringmanyfactorstodrawupthesuperiorproject,endcompletionoriginallytimedesign.KEYWORDS:Thedesignbothsideofthespecifyingofcraftrulesdistance,Thecraftrulesdistanceaspect,ThesuperiorprojectII洛阳理工学院毕业设计（论文）目录前言........................................................................................1第1章零件的分析...................................................21.1零件的作用..............................................................21.2零件的工艺分析...............................................2第2章确定毛坯、画毛坯图......................4第3章工艺规程的设计....................................63.1定位基准的选择...............................................63.1.1粗基准的选择...............................................63.1.2精基准的选择...............................................63.2制订工艺路线.......................................................73.3选择加工设备及刀、夹、量具...73.4加工工序设计.......................................................9第4章专用夹具设计........................................264.1专用夹具设计分析....................................264.1.1定位基准的选择....................................264.1.2切削力及夹紧力的计算..............264.2定位误差的分析............................................274.3夹具设计及操作的简要说明.......28结论....................................................................................34谢辞........................................................................................35参考文献.............................................................................36III洛阳理工学院毕业设计（论文）前言毕...
