1、加工工藝規(guī)程制訂及其工序?qū)Ｓ脢A具的設(shè)計(jì)X5020B立式升降臺(tái)銑床撥叉殼體摘要：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(guò)對(duì)X5020B立式升降臺(tái)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(jiǎn)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
