Combination machine is designed according the fundamental , which highly centralized ,or , more correctly it can process one working procedure or more different working procedures at one time . Combination machine was developed in the end of industrial production compared with traditional machine; combination machine has many advantages , such as high efficiency , high accuracy and low cost . It is composed of some general parts , such as bed ,column ,work able ,power unit ,and some special parts designed according to different work piece machining need. The preface of a lot of works can be completed on the combination machine, but in regard to the majority current usage of combination machine, then and primarily used for the flat surface to process and the bore to process two big work preface. The main part including :(1) Formulating technological plan We,ve learned the characteristic of the part designed ,accuracy and specification ,locating and fixing ,productivity and machining structure by the practice .Then the technological operation and work order can be determined which can be finished in combination machine.(2) Combination machine frame design determines the interrelation of the different part in the machining tool ,select general parts and tool oriented .Then compute cut feed and productivity finally draw a sketch map of the machine .(3) Combination machine parts design including headstock、proper transmission layout 、shaft and gear move freely without interference which ensure the stability and accuracy during transmission ,then design dedicated select bearings and engine etc.(4) It adopts many hydraulic control valves ,which ensure the stability ,circulation and accuracy .Keywords: combination machine ;design ;process ;function目 錄摘 要1AbstractII目 錄III1 緒論11.1 課題研究意義11.2鏜孔專用設(shè)備應(yīng)用11.3 鏜孔專用設(shè)備21.3.1多軸頭21.3.2 多軸箱21.3.3多軸鉆床31.3.4 自動更換主軸箱機床31.4 鏜孔專用設(shè)備趨勢42 組合機床的總體設(shè)計52.1 組合機床方案的制定52.1.1 制定工藝方案52.1.2 確定組合機床的配置形式和結(jié)構(gòu)方案。52.2 確定切削用量及選擇刀具72.2.1 確定工序間余量72.2.2 選擇切削用量72.2.3 確定切削力、切削扭矩、切削功率72.2.4 選擇刀具結(jié)構(gòu)82.2.5 被加工零件工序圖92.2.6 機床尺寸聯(lián)系總圖103 鏜孔專用機床及夾具設(shè)計143.1 夾具的初步設(shè)計方案143.2 機床的初步設(shè)計143.2.1 動力部件的選擇143.2.2 確定切削用量及選擇刀具153.2.3 確定切削力，切削扭矩，切削功率153.3 夾具設(shè)計的計算173.3.1 受力計算173.3.2 夾緊力173.4 機床的液壓滑臺系統(tǒng)的具體設(shè)計183.4.1 液壓缸所受的外負載183.4.2 擬定液壓系統(tǒng)原理圖193.4.3 液壓系統(tǒng)的計算和選擇液壓元件204 主軸箱設(shè)計244.1 專用主軸箱設(shè)計244.2 傳動系統(tǒng)的設(shè)計244.2.1 電動機的選擇244.2.2 電動機功率的選擇244.2.3 傳動系統(tǒng)總傳動比的確定及各級分傳動比的分配254.3 齒輪的設(shè)計及參數(shù)的確定254.3.1 齒輪的設(shè)計264.3.2 齒輪參數(shù)的確定284.4 軸承的選擇31結(jié) 論33致 謝34參考文獻35
