1、本科畢業(yè)設(shè)計(jì)(論文)通過答辯摘要本次設(shè)計(jì)拋開以往的設(shè)計(jì)思想,濃縮了一個(gè)新方案。通過對X5020B立式升降臺銑床撥叉殼體兩種加工工藝路線的比較分析,選定前者。該方案是以三個(gè)面作為基準(zhǔn),實(shí)現(xiàn)基準(zhǔn)統(tǒng)一原則,簡化了隨行夾具的設(shè)計(jì),從而在保證所要求的質(zhì)量和勞動(dòng)生產(chǎn)率指標(biāo)的前提下降低了生產(chǎn)成本。而且專用夾具的設(shè)計(jì)嚴(yán)格按照先收集和研究有關(guān)資料,再確定夾具的結(jié)構(gòu)方案,然后繪制夾具總圖,最后確定并標(biāo)注有關(guān)尺寸及技術(shù)條件的步驟進(jìn)行,充分體現(xiàn)了提高勞動(dòng)生產(chǎn)率、保證加工質(zhì)量、降低勞動(dòng)強(qiáng)度的原則,論文中將以詳細(xì)的計(jì)算和說明證明這一說法。關(guān)鍵詞:撥叉殼體;加工工藝;夾具第1頁共36頁本科畢業(yè)設(shè)計(jì)(論文)
