撥叉的CADCAPP設(shè)計及夾具PROE造型說明書畢業(yè)論文.doc

-I-撥叉的CAD/CAPP設(shè)計及夾具PROE造型摘要我的畢業(yè)設(shè)計題目是撥叉的CAD/CAPP設(shè)計及夾具PROE造型，本次的畢業(yè)設(shè)計中我的論文分為三大部分：第一部分主要是撥叉的工藝規(guī)程設(shè)計。其中包括采用CAD完成了零件圖，用PROE完成了毛坯圖的繪制。完成了撥叉的工藝規(guī)程設(shè)計，主要包括確定設(shè)計類型，確定毛坯制造形式，制定工藝路線，選擇機床及工藝設(shè)備，確定機械加工余量，工序尺寸和毛坯尺寸，以及切削用量和基本工時的確定。運用CAPP軟件完成了撥叉的機械加工過程卡和工序卡。第二部分主要是撥叉的夾具設(shè)計。在這一部分的內(nèi)容中，主要包括零件的定位基準的選擇，定位機構(gòu)的設(shè)計，定位遠見的尺寸的確定，定位誤差的分析。設(shè)計夾具主要完成了加緊機構(gòu)的設(shè)計，加緊力及夾緊機構(gòu)的設(shè)計，夾緊力及夾緊方向的確定，以及所選擇的夾緊元件。夾緊機構(gòu)主要是采用螺母和壓板的手動壓緊，其定位和加緊機構(gòu)簡單，方便可靠。第三部分主要是采用Pro/engineer完成了撥叉的夾具造形。其中主要是詳述了撥叉零件的繪制過程。關(guān)鍵詞：撥叉；Pro/engineer；CAPP-II-TheCAD/CAPPDesignOfStirTheForkAndCreateTongsShapeWithPro/EngineerAbstractThetopicofmygraduatedesignistheCAD/CAPPdesignofstirtheforkandcreatetongsshapewithPro/engineer,inthisgraduatedesign,mygraduatethesisprimarilyisdividedintothreebigparts:Thefirstpartisthecraftruledesignofstirthefolkprimarily.AmongthemincludingadopttheCADcompletedthesparepartsdiagram,semi-finishedproductdiagramdraws.Completedtostirthecraftrulesdistanceofthefolkdesign,primarilyincludingmakesuretheproductiontype,makingsurethesemi-finishedproductmanufacturingform,establishingthecraftroute,choosingthemachinebedandcraftequipments,makingsurethemachineprocessremainingmeasures,workprefacesizewithsemi-finishedproductsizeandthesizeofslicethedosage,makingsurethebasicman-hourreally.ApplyingCAPPsoftwaretocompletethemachineofthefolkprocessandtheprocesscardwiththeworkprefacecard.Thesecondpartprimarilyisthedesignoftongstostirthefork.Inthispartofcontenses,includingthefiducialchoiceinfixedpositionofthesparepartsprimarily,thedesignofthefixedpositionoftheorganization,fixedpositionandtheanalysisforthesizeofsettling,positioningerrormargin.Thetongsdesignincludingcompletedtheclipdesignofthetightorganizationprimarily,clipthetightdintandsetupthedirectiontosettlreally,andchooseofthecliptightofapiece.Clipthetightorginationprimarilyistoadopttheboltandtheknothole-III-withpressmovetocompresstights,thefixedpositionwithclipthetightorginationsimple,convenienceanddependable.ThethirdpartisthetongstoadoptPro/engineercompletingtostirtheforkshapeprimarily.Amongthemprimarilyfinishedtheprocessofdrawingofthestirtheforkindetail.Keywords:stirthefork；Pro/engineer；CAPP-IV-目錄摘要.IAbstract.II第1章緒論.6第2章零件的分析.72.1撥叉的作用.72.2撥叉的加工工藝過程分析.72.2.1撥叉的分析.72.2.2合理選擇定位基準.72.2.3表面加工法.72.2.4加工順序安排.8第3章零件的工藝規(guī)程設(shè)計.93.1確定零件生產(chǎn)類型.93.1.1確定生產(chǎn)類型的依據(jù)生產(chǎn)綱領(lǐng).93.1.2確定生產(chǎn)類型.93.2確定毛坯的制造方式.93.3制訂工藝路線.103.3.1基準的選擇.103.3.2零件表面加工方法的選擇.113.3.3熱處理的位置.123.3.4零件的表面加工順序的劃分安排.123.3.5工藝方案比較.133.4機床及工藝裝備的選擇.143.4.1機床的選擇.143.4.2刀具的選擇.153.4.3量具的選擇.153.5機械加工余量工序尺
