學生畢業(yè)設(shè)計(論文)題目：CA6140機床法蘭盤課程設(shè)計姓名：班級、學號：系(部)：專業(yè)：數(shù)控自動化指導教師：開題時間：完成時間：摘要工藝學是以研究機械加工工藝技術(shù)和夾具設(shè)計為主技術(shù)學科，具有很強的實踐性，要求學習過程中應(yīng)緊密聯(lián)系生產(chǎn)實踐，同時它又具有很強的綜合性，本次畢業(yè)設(shè)計的課題是CA6140車床法蘭盤加工工藝規(guī)程及某一工序?qū)Ｓ脢A具設(shè)計，主要內(nèi)容如下：首先，對零件進行分析，主要是零件作用的分析和工藝分析，通過零件分析可以了解零件的基本情況，而工藝分析可以知道零件的加工表面和加工要求。根據(jù)零件圖提出的加工要求，確定毛坯的制造形式和尺寸的確定。第二步，進行基面的選擇，確定加工過程中的粗基準和精基準。根據(jù)選好的基準，制訂工藝路線，通常制訂兩種以上的工藝路線，通過工藝方案的比較與分析，再選擇可以使零件的幾何形狀、尺寸精度及位置精度等技術(shù)要求得到合理的保證的一種工序。第三步，根據(jù)已經(jīng)選定的工序路線，確定每一步的切削用量及基本工時，并選擇合適的機床和刀具。對于粗加工，還要校核機床功率。最后，設(shè)計第三道工序鉆法蘭盤孔的夾具。先提出設(shè)計問題，再選擇定位基準，然后開始切削力、夾緊力的計算和定位誤差的分析。然后把設(shè)計的過程整理為圖紙。通過以上的概述，整個設(shè)計基本完成。關(guān)鍵詞機械；加工工藝；夾具設(shè)計ABSTRACTAspecializedmainspecializedcoursethatmechanicalmanufacturingengineeringisstudiedismachinery,relymainlyonstudyingmachiningtechnologyandjigtodesigntechnologicaldiscipline,haveverystrongpracticality,requirethatshouldcontactproductionpracticescloselyinthelearningprocess,atthesametimeithascomprehensivetheverystrongone,ThesubjectofthisgraduationprojectisthatCA6140latheringflangeprocessingtechnologyrulesandspecial-purposejigofacertainprocessaredesigned,themaincontentisasfollows:Firstofall,analyse,itismainlyanalysisofthefunctionofthepartandcraftanalysistothepart,throughpartanalysecanfindoutaboutbasicsituationofpart,andcraftanalysemayknowtheprocessingsurfaceofthepartandisitrequiretoprocess.Theprocessingdemandputforwardaccordingtothepartpicture,confirmthemanufactureformoftheblankandsurenessofthesize.Thesecondstep,carryonthechoicethebase,confirmthickdatumandprecisedatumintheprocessingcourse.Accordingtothedatumchosen,makethecraftroute,usuallymakethecraftrouteofmorethantwokinds,withanalysingthroughthecomparisonofthecraftscheme,andthenchoosingbeabletomakesuchspecificationrequirementsastheprecisionofgeometryform,sizeofthepartandprecisionofposition,etc.getakindofprocessoftherationalassurances.Thethirdstep,accordingtothealreadyselectedprocessroute,confirmforeverystepsofcuttingconsumptionandbasicman-hour,choosesuitablelatheandcutter.Toroughmachining,willcheckthepowerofthelathe.Finally,designthethirdprocess-thejiggettingintotheholeoftheringflange.Putforwardthequestionofdesigningfirst,andthenchoosetoorientthedatum,thenthecalculationthatbeginstocutstrength,clampstrengthandanalysisofthelocalizationerror.Thenputthedesigncourseinorderasthedrawing.Throughthesummaryoftheabove,designandfinishbasicallyentirely.Keywords:machine；Processthecraft；Thetongsdesign目錄序言.11零件的分析.21.1零件的作用.21.2零件的工藝分析.22工
