1、標(biāo)準(zhǔn)文檔摘要工藝學(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CA6140車床法蘭盤加工工藝規(guī)程及某一工序?qū)S脢A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
2、工藝路線,通過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)要求得到合理的保證的一種工序。第三步,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)床和刀具。對(duì)于粗加工,還要校核機(jī)床功率。最后,設(shè)計(jì)第三道工序—鉆法蘭盤孔的夾具。先提出設(shè)計(jì)問題,再選擇定位基準(zhǔn),然后開始切削力、夾緊力的計(jì)算和定位誤差的分析。然后把設(shè)計(jì)的過程整理為圖紙。通過以上的概述,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)實(shí)用文案標(biāo)準(zhǔn)文檔ABSTRACTAspecializedmainspecialized
