1、淮安廣播電視大學(xué)畢業(yè)論文撥叉的CAD/CAPP設(shè)計(jì)及夾具PROE造型摘要我的畢業(yè)設(shè)計(jì)題目是撥叉的CAD/CAPP設(shè)計(jì)及夾具PROE造型，本次的畢業(yè)設(shè)計(jì)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(jì)。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(jì)，主要包括確定設(shè)計(jì)類型，確定毛坯制造形式，制定工藝路線，選擇機(jī)床及工藝設(shè)備，確定機(jī)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(shí)的確定。運(yùn)用CAPP軟件完成了撥叉的機(jī)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(jì)。在這一部分的內(nèi)容中，主要包括零件的定位基準(zhǔn)的選擇，定位機(jī)構(gòu)的設(shè)計(jì)，定
2、位遠(yuǎn)見的尺寸的確定，定位誤差的分析。設(shè)計(jì)夾具主要完成了加緊機(jī)構(gòu)的設(shè)計(jì)，加緊力及夾緊機(jī)構(gòu)的設(shè)計(jì)，夾緊力及夾緊方向的確定，以及所選擇的夾緊元件。夾緊機(jī)構(gòu)主要是采用螺母和壓板的手動(dòng)壓緊，其定位和加緊機(jī)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-IV-淮安廣播電視大學(xué)畢業(yè)論文TheCAD/CAPPDesignOfStirTheForkAndCreateTongsShapeWithPro/EngineerAbstractThetopicofmygraduatedesig
