摘 要：從企業(yè)實(shí)際需求出發(fā)，在全面分析被加工零件的基礎(chǔ)上，指出采用現(xiàn)有設(shè)備的不足，不僅工人勞動(dòng)強(qiáng)度大，而且生產(chǎn)率低，不利于保證零件加工精度．研制出了16孔單工位組合鉆床，解決了上述問(wèn)題．

關(guān)鍵詞：組合鉆床；主軸箱；傳動(dòng)設(shè)計(jì)；實(shí)驗(yàn)

目前，我國(guó)中、小型企業(yè)的產(chǎn)品質(zhì)量和生產(chǎn)效率都需要有一個(gè)新的提高．但是加工手段卻遠(yuǎn)遠(yuǎn)不能滿足需要．許多中小型企業(yè)都結(jié)合自己的實(shí)際對(duì)設(shè)備的技術(shù)狀態(tài)進(jìn)行改進(jìn)，通過(guò)強(qiáng)化自身．以求自我發(fā)展.
小型拖拉機(jī)零件(12．54．101前蓋)如圖1所示，采用普通鉆床逐孔加工法，工人頻繁忙于裝夾工件、起動(dòng)機(jī)床、進(jìn)刀、退刀、停車(chē)及卸工件，不僅勞動(dòng)強(qiáng)度大，而且生產(chǎn)率和加工精度低．每臺(tái)小型拖拉機(jī)上用前蓋一件，目前每臺(tái)小拖的市場(chǎng)銷(xiāo)量為1OO萬(wàn)臺(tái)，研制加工該零件的組合鉆床不但能提高生產(chǎn)效率，降低設(shè)備占用率，降低工人勞動(dòng)強(qiáng)度，而且還會(huì)為廠家?guī)?lái)可觀的經(jīng)濟(jì)效益．



Abstract：In view of the actual conditions of enterprises and on the basis of overall analysing workpece structure features，accuracy of size，surface roughness，accuracy of distance between drilled holes and other technical requirements，this article points out that the existing eqmpments used to manufacture workpieces may result in lower productivity，greater intensity of labour and worse workng accuracy.16 hole combination drilling machine resolves above problems

Key words：Combination drilling machine ；Spindle box ；Design of fixture；Experiment

At present, China's small and medium enterprises in product quality and production efficiency are the need for a new increase. But the processing means is far from sufficient. Many small and medium enterprises with their actual technical state of equipment improvements, through strengthening its own. In order to self-development.
