【正文】 零件如醫(yī)療手術(shù)真的鉆削加工，針對工件的特點，涉及采用了相應(yīng)設(shè)備和裝置如氣壓上料，由于工件較小(~4mm),所以加工精度提到設(shè)計要求中，鉆削微小的偏差都能導致工件的報廢，因此它也是此次設(shè)計的關(guān)鍵部分。對于批量生產(chǎn)這種工件來說，更是人力和資料的浪費，面對此種現(xiàn)狀，各個廠家都在采用技術(shù)革新，來縮短加工時間和降低廢品率 。對于醫(yī)療手術(shù)針這類微小工件，加工它只是在期末端鉆削一個微孔，只需幾秒鐘的時間。 在我國由于工業(yè)起步較晚，所以相對于美英等國的制造業(yè)仍有一段差距，特別是在高精密的儀器制造方法，差距較大。 采用自動化機床，具有其顯著的特點，通過它可大大縮減在生產(chǎn)過程中的輔助時間，這樣，就大大提高生產(chǎn)效率，譬如，生產(chǎn)中一般零件的裝卸就占據(jù)所加工的 40%,而采用自動化生產(chǎn)線時，其裝卸都是有規(guī)律地自動裝卸，所需時間較短，同時，自動生產(chǎn)線還避免了人的主觀和客觀上的誤差，大大提高了加工精度，當然，采用自動線，勢必增加機床的復(fù)雜程度，對工人的素質(zhì)需要也相應(yīng)的提高。自動上下料裝置是自動機床和自動線設(shè)計中復(fù)雜程度高而且難度較大的組成部分之一。 本設(shè)計是一帶自動上下料裝置的高精度精密鉆床。 關(guān)鍵詞 高精度 微型 自動上下料 畢業(yè)設(shè)計說明書（論文）外文摘要 Title: A High Accuracy That Takes Voluntarily About Material Installation Precise Drilling Machine Abstract: It is a high accuracy that takes voluntarily about material installation precise drilling machine. Drilling machine is a kind of most ordinary machine tool in mechanical profession, however, this design characteristic is: High accuracy at the same time adopts voluntarily about material for surmounting many shorting of former artificial about material and designing , this has increased the difficulty of design. On automatic, next material installation is one of plex position parts with high level and greater difficulty in the bed of automatic machine and the design of transfer matic. On automatic taking off material installation the work pleted passes scattered in disorder out of order working element directional anization is directional to put them on the clamping apparatus of machine tool in order in order , then, queue up , and unload type workpiece from clamping apparatus after processing is over. The mini precise drilling machine of this design makes the efficiency in batch production notable because of having adopted voluntarily about material installation , has at the same time reduced production cost, the object that he processes is small element as medical operation needle get into to cut processing , according to the characteristic of workpiece, have been concerned with to adopt corresponding equipment and installation expects on atmospheric pressure, since workpiece is less( ～ 4 mm), so, processing precision to mention go to design requirement, get into to cut small deviation can cause workpiece scrap , therefore it is also the crucial part of this design. In this design, I have adopted atmospheric pressure on material, flexible card is expected tightly, under ejector pin and precision differential trimming etc. means.
