1、摘要工藝學(xué)是以研究機(jī)械加工工藝技術(shù)和夾具設(shè)計(jì)為主技術(shù)學(xué)科，具有很強(qiáng)的實(shí)踐性，要求學(xué)習(xí)過(guò)程中應(yīng)緊密聯(lián)系生產(chǎn)實(shí)踐，同時(shí)它又具有很強(qiáng)的綜合性，本次畢業(yè)設(shè)計(jì)的課題是軸承蓋加工工藝規(guī)程及夾具設(shè)計(jì)主要內(nèi)容如下：首先，對(duì)零件進(jìn)行分析，主要是零件作用的分析和工藝分析，通過(guò)零件分析可以了解零件的基本情況，而工藝分析可以知道零件的加工表面和加工要求。根據(jù)零件圖提出的加工要求，確定毛坯的制造形式和尺寸的確定。第二步，進(jìn)行基面的選擇，確定加工過(guò)程中的粗基準(zhǔn)和精基準(zhǔn)。根據(jù)選好的基準(zhǔn)，制訂工藝路線，通常制訂兩種以上的工藝路線，通過(guò)工藝方案的比較與分析，再選擇可以使零件的幾何形狀、尺寸精度及位置精度等技術(shù)要求得到合理的
2、保證的一種工序。最后，根據(jù)已經(jīng)選定的工序路線，確定每一步的切削用量及基本工時(shí)，并選擇合適的機(jī)床和刀夾具。對(duì)于粗加工，還要校核機(jī)床功率。然后把設(shè)計(jì)的過(guò)程整理為圖紙。通過(guò)以上的概述，整個(gè)設(shè)計(jì)基本完成。關(guān)鍵詞：機(jī)械；加工工藝；夾具設(shè)計(jì)全套圖紙，加ABSTRACTAspecializedmainspecializedcoursethat"mechanicalmanufacturingengineeringisstudied"ismachinery,relymainlyonstudyingmachiningtechnologyandjigtodesigntechnologicaldiscipline
