1、XX學(xué)院畢業(yè)設(shè)計(論文)法蘭機(jī)械加工工藝及夾具設(shè)計班級專業(yè)教學(xué)系指導(dǎo)老師完成時間年月日至年月日I摘要本次設(shè)計的主要內(nèi)容是法蘭機(jī)械加工工藝及夾具設(shè)計,法蘭主要是與其它零件配對使用,其主要加工表面及控制位置為外圓和內(nèi)孔。由零件要求分析可知,保證外圓和內(nèi)孔尺寸的同時應(yīng)該盡量保證其同軸度,這對于后工序裝配和總成使用上來說都有重要影響。所以,工序安排時,采取以大外圓粗定位夾緊加工后,對外圓進(jìn)行車削加工同時成型。因其粗糙度為Ra3.2,可通過粗車、半精車滿足。對于車削內(nèi)孔時,主要以法蘭的凸臺定位,控制其自由度,以達(dá)到加工出
2、來的產(chǎn)品滿足要求并且一致性好的目的。本文的研究重點在于通過對法蘭的工藝性和力學(xué)性能分析,對加工工藝進(jìn)行合理分析,選擇確定合理的毛坯、加工方式、設(shè)計高效、省力的夾具以及設(shè)計出簡單、實用的數(shù)控加工程序,通過實踐驗證,最終加工出合格的法蘭零件。關(guān)鍵詞:法蘭,加工余量,工藝,夾具IIAbstractEnableproducingthetargetinprocessofproductionrawmaterials,theblank,stateofqualityandquantityonpartbecomealwaysta
