填料箱盖的加工工艺及专用夹具设计--毕业论文.doc

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PackingboxcoverprocessingandspecialfixturedesignABSTRACTThemachinemadeinthemachineprocesses,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,Thesuperiorproject目录TOC\o"1-3"\t""\h\z\uHYPERLINK\l_Toc13584前言PAGEREF_Toc135841HYPERLINK\l_Toc27100第1章零件的分析PAGEREF_Toc271002HYPERLINK\l_Toc288351.1零件的作用PAGEREF_Toc288352HYPERLINK\l_Toc280901.2零件的工艺分析PAGEREF_Toc280902HYPERLINK\l_Toc32605第2章确定毛坯、画毛坯图PAGEREF_Toc326054HYPERLINK\l_Toc14383第3章工艺规程的设计PAGEREF_Toc143836HYPERLINK\l_Toc274503.1定位基准的选择PAGEREF_Toc274506HYPERLINK\l_Toc14123.1.1粗基准的选择PAGEREF_Toc14126HYPERLINK\l_Toc308733.1.2精基准的选择PAG
