【正文】 用組合機床及專用夾具，完成“三圖一卡”及夾具的全套圖紙。根據(jù)機械制造中的相關(guān)公式選擇、計算各工藝參數(shù)，填寫加工工藝規(guī)程。但同時也要看到，我們國家的制造業(yè)和西方發(fā)達資本主義國家的制造業(yè)還 有差距，而且在某種層度上說，差距還很大，這就要求我們國家還要付出更大的努力去提高我國的制造業(yè)在世界制造業(yè)中的地位，使我國的制造業(yè)對我國的經(jīng)濟發(fā)展能夠發(fā)揮更大的作用，為人民和人類帶來更大的幫助。尤其是在最近幾十年了，發(fā)達的資本主義國際憑借其先進的制造技術(shù)，利用其強大的科技和財政實力獲得了巨大的經(jīng)濟利益。那時候的課程設(shè)計太過于簡單，涉及的知識也不夠全面，也不夠深入，而且我讀研的專業(yè)就是機械制造及其自動化專業(yè)，所以這樣的 畢業(yè)設(shè)計對我及其重要，不但使我更扎實的學好該專業(yè)的知識，更是對我將來的發(fā)展具有及其重要的意義，所以我一定要努力圓滿的完成該畢業(yè)設(shè)計。在大一到大四的四年中，我很好的完成了機械測繪、機械原理、機械設(shè)計及機械制造工藝學相關(guān)的專業(yè)課的課程設(shè)計。 關(guān)鍵詞 ： ZS1105 柴油機箱體；加工工藝；鏜床專用夾具 II Abstract According to the structural characteristics of ZS1105 diesel engine, the design is based on the argument in full right to develop the processing technology cabi line. According to the related machine selection formula to calculate the process parameters, and plete processing of order. In addition, the processing conditions according to the actual calculation of the corresponding time scale, and the selection of appropriate economic, rational process of machine tools and tool processes pleted card. In addition to the above, but also the design process for the special cabi bination drilling machine and special fixtures to plete the threemap and one card and a full set of fixtures drawings.
