Moreover the combination drilling machine majority is composed of general part, the development cycle is short,and is advantageous for the design, the manufacture and use maintenance, the cost is low. Moreover the machine easy to transform, when product and process changes, the general part can also the reuse,the efficiency be good.So combination of machine tools is very widespread in production in enormous quantities application.Keywords: combination drilling machine spindle box middle baseII徐州工程學(xué)院畢業(yè)設(shè)計(論文)目 錄1 組合機床概述11.1 引言11.2 組合機床組成及特點11.3 組合機床的工藝范圍及配置形式21.3.1 組合機床的工藝范圍21.3.2 組合機床的配置形式31.4 組合機床的設(shè)計步驟51.4.1 調(diào)查研究51.4.2 總體方案設(shè)計51.4.3 技術(shù)設(shè)計61.4.4 工作設(shè)計62 組合鉆床設(shè)計72.1 零件分析72.2 組合鉆床設(shè)計的組成及設(shè)計任務(wù)72.2.1 組合鉆床設(shè)計的組成72.2.2 本課題主要任務(wù)72.3 工藝方案及基準的選擇82.3.1 確定組合鉆床工藝方案的機本原則82.3.2 組合鉆床工藝方案的一般步驟92.3.3確定切削力、切削轉(zhuǎn)矩、切削功率及刀具耐用度102.4 組合鉆床主軸箱概況102.4.1 組成102.4.2主軸箱的通用零件102.5 工序與計算112.5.1 加工條件112.5.2計算切削速度、主軸轉(zhuǎn)速113多軸箱的設(shè)計133.1 多軸箱的基本結(jié)構(gòu)和表達方法133.1.1 多軸箱的簡介133.1.2多軸箱的組成133.1.3多軸箱總圖繪制方法133.2 多軸箱通用零件133.2.1 通用箱體類零件143.2.2 通用主軸143.2.3 通用傳動軸143.2.4 通用齒輪和套143.3通用多軸箱的設(shè)計分析153.3.1 繪制多軸箱設(shè)計原始依據(jù)圖153.3.2 確定多軸箱輪廓尺寸163.3.3 主軸型式和直徑的確定163.3.4主軸箱所需進給力計算183.3.5 主軸箱所需功率計算183.3.6 動力部件193.3.7多軸箱傳動設(shè)計193.3.8 計算傳動軸的坐標233.3.9 潤滑油泵和手柄軸的安置244 中間底座的設(shè)計264.1 引言264.2 中間底座的作用及基本要求264.2.1 中間底座的作用264.2.2 對于中間底座的基本要求264.3 中間底座的設(shè)計原則274.3.1 合理選擇截面形狀和尺寸274.3.2 合理布置加強筋274.4 中間底座壁厚、加強筋厚度的選擇274.5 如何提高連接處的局部剛度和接觸剛度284.6 中間底座結(jié)構(gòu)工藝性28結(jié)論29參考文獻30致謝31附錄322
