1本科畢業(yè)設(shè)計（論文）題 目 汽車變速箱鏜孔組合機(jī)床設(shè)計 學(xué) 院 工業(yè)制造學(xué)院 專 業(yè) 機(jī)械設(shè)計制造及其自動化 學(xué)生姓名 學(xué) 號 年級 指導(dǎo)教師 職稱 二 0 一五年 三 月 二十五日2摘要本設(shè)計介紹了汽車變速箱鏜孔組合機(jī)床的設(shè)計，其中包含了零件加工工藝的確定，設(shè)計中首先要了解工件的加工工藝路線及工序的計算，確定鏜孔主軸的直徑，初步選用電機(jī)型號及機(jī)床各部分部件。編制三圖一卡（被加工零件工序圖，加工示意圖，機(jī)床聯(lián)系尺寸圖，機(jī)床生產(chǎn)率計算卡） 。在多軸箱設(shè)計中，確定傳動系統(tǒng)，計算主軸坐標(biāo)，傳動部件的校核及主軸箱的總圖繪制。本設(shè)計將車床和臥式鏜床結(jié)構(gòu)有機(jī)地結(jié)合為一體，降低了機(jī)器成本，而且節(jié)省了加工時間，提高了工作生產(chǎn)效率。關(guān)鍵詞：變速箱 主軸 總圖繪制 多軸箱 3AbstractThe design on the Box axlebox more than the design, which includes parts of the processing technology of identification, design is first necessary to understand the workpiece in the processing line and process of calculation to determine Tapping the spindle diameter, the initial choice of motor Model and some parts of the machine. Figure 1 of the three cards (the processing parts process map, diagram processing, machine tools Contact size map, machine tool productivity calculation card). In multi-axle box design, drive system established to calculate coordinates spindle, transmission parts of the spindle box and check the total mapping. This design will be drilling, tapping combination of the two as one and reduce the cost of machinery, processing and save time, improve the work efficiency of production.
