摘要
本文是立式鉆床用軸均布多軸頭設(shè)計(jì)，可調(diào)式多軸頭各軸在圓周方向均布且方向可方便地沿直徑方向同步調(diào)整，以適應(yīng)多種小批量生產(chǎn)條件下法蘭盤類零件的螺孔加工。固定試式多軸頭是根據(jù)一個(gè)典型法蘭盤類零件而設(shè)計(jì)的，用于零件中大批量生產(chǎn)要求。
多軸頭架的設(shè)計(jì)參數(shù)來源于一般的加工工藝條件，以適應(yīng)更廣闊的加工范圍。針對(duì)工廠里多孔鉆削時(shí)，孔徑一般較小，多在10cm左右，而且大部分是箱體、法蘭盤等，箱體、法蘭盤多為鑄造件，材料是鑄鐵，也有個(gè)別的被加工零件的材料是低碳鋼。根據(jù)這些工件的切削條件，可以確定多軸頭架的工藝主參數(shù)。
主參數(shù)確定后便可以進(jìn)行多軸頭架的總體設(shè)計(jì)。多軸頭架的傳動(dòng)原理是通過齒輪嚙合增加鉆削軸的軸數(shù)，以滿足多孔加工的要求。通過二級(jí)齒輪嚙合，輸入軸和輸出軸的轉(zhuǎn)向沒變，但由于齒輪分支傳動(dòng)，變成多根輸出軸。
為了保證加工生產(chǎn)條件的安全，加上多軸頭工作時(shí)裝隔離裝置比較困難，所以必須嚴(yán)格校核軸頭架的強(qiáng)度，以免發(fā)生事故或達(dá)不到加工要求。
可以看出，改裝后的多軸鉆床，可以同時(shí)完成多個(gè)孔的鉆、擴(kuò)、鉸等工序。工藝范圍可以滿足一般加工情況的孔類鉆削要求?？烧{(diào)多軸頭架可以起到提高生產(chǎn)效率、降低成本、提高孔系加工精度等作用。參照該調(diào)節(jié)原理可進(jìn)行其他任意孔系加工裝置的設(shè)計(jì)，還可以用于攻絲、擴(kuò)、锪孔等加工裝置。此外該裝置具有結(jié)構(gòu)簡單、操作方便、應(yīng)用范圍廣等特點(diǎn)，值得推廣。

Abstract
The design of multiple spindles heads for drilling machine whose drills spindles are adjustable or fixed are introduced
The adjustable spindles of the multiple spindles heads are located evenly in the circuit and can be adjusted synchronism on the diameter’s direction to meet the small scale production needs of the screw hole manufacture for flange plate parts.And the fixed multiple spindles heads is design for the big scale production needs of the screw hole manufacture for flange plate parts,it can’t be used to manufacture another farts, because it’s spindle distance is designed for the only part.
The design of multiple spindles heads include three parts : the total design, the transfer system design , and the constructive design
Because of the un-development in our manufacture industry ,most company’s plant lack of the machine to drill multiple holes at the same time , and it’s a waste of funding on the manufacturing facilities which will be laid after the parts are produced . so the economic multiple spindles heads enable the normal company to drill the multiple holes in a fast way .And same company gained the economic performance by the way of reequips the machine tools. It’s the fact that the reequipped drilling machine can satisfy the process precision requirement .so the design is feasible.
Based on the design of the multiple spindles heads , we can also design the others to the manufacture of the other flange plant parts.
Key words: drilling machine ;adjustable; multiple spindles heads;
