1、摘要機(jī)械加工行業(yè)作為一個傳統(tǒng)而富有活力的行業(yè)，近十幾年取得了突飛猛進(jìn)的發(fā)展，在新經(jīng)濟(jì)時代，行業(yè)呈現(xiàn)了新的發(fā)展趨勢，由此對其質(zhì)量、性能要求有了新的變化?，F(xiàn)在機(jī)械加工行業(yè)發(fā)生著結(jié)構(gòu)性變化，工藝工裝夾具的設(shè)計與改良已成為企業(yè)生存和發(fā)展的必要條件，工藝工裝夾具的設(shè)計與改良直接影響加工產(chǎn)品的質(zhì)量與性能。本課題主要是針對支架工藝規(guī)程和加工3×Φ7螺紋孔工裝夾具設(shè)計及其調(diào)研,文中介紹了支架的加工工藝規(guī)程，以及在制定過程中所遇到問題的分析、工時定額、切削用量的計算等。同時通過對夾具整體方案的設(shè)計，定位機(jī)構(gòu)的設(shè)計，以及了解了專用夾具的設(shè)計要求，詳細(xì)設(shè)計出了支架零件鉆3×Φ7螺紋孔的夾具機(jī)構(gòu)，并
2、對加工中用到的夾具的設(shè)計過程，包括定位、夾緊及誤差進(jìn)行了分析和計算。通過設(shè)計，進(jìn)一步熟悉了加工工件工藝分析過程，了解夾具的設(shè)計規(guī)程，通過調(diào)研和查閱資料，從而設(shè)計出最佳的加工工藝方案和工件專用的夾具。通過刀具的合理選擇以及夾具的實(shí)際設(shè)計，掌握了一個零件加工工藝方案如何制定、夾具如何設(shè)計，并提高分析問題解決問題的能力。通過使用AutoCAD和Proe進(jìn)行夾具設(shè)計，進(jìn)一步提高了計算機(jī)繪圖能力，為我以后的學(xué)習(xí)和工作奠定了良好的基礎(chǔ)。關(guān)鍵詞：支架；工藝方案；夾具；刀具ABSTRACTMechanicalprocessingindustryasatraditionalandvigorou
