摘　　要

      （一）電機機座鉆孔組合機床是大型組合機床，它的配置型式具有固定式液壓夾緊的單工位組合機床，這類組合機床夾具和工作臺都是固定不動的，動力滑臺實現進給運動。滑臺上的動力箱實現切削運動，根據工件結構特點，以及精確要求，采用結合面為定值基準面。在基準面對應的另一圓柱面上，用壓塊壓緊，由于結合面的加工精度較高，以它為基面，完全可以達到要求的加工精度。
     （二）幾何機床總體設計----三圖一卡①“被加工零件工序圖”它是組合機床的設計的主要依據，它是制造使用，檢修和調整機床的重要技術條件②繪制加工示意圖，它是刀具夾具，多軸箱，液壓電器裝置設計及通用部件選擇主要原始資料，它是調整機床，刀具及試車依據。③繪制聯系和運動關系及檢驗機床各部件相對于位置及聯系是否滿足加工要求，通用部件的選擇是否合適，并為進一步開展主軸箱，夾具等專用部件，零件的設計提供依據。④相對生產率計算卡，它用來反映機床的加工過程，完成這一動作所需要的時間，切削用量，機床生產率及機床負荷率。
    (三)組合機床主軸箱設計，按專用要求進行設計，由通用零件組成，其主要作用是根據被加工零件的要求，安排各主軸位置并將動力和運動由電機或動力部件傳給各主軸，使之得到要求的轉速，機床主軸箱選用400*400,用中間傳動軸帶動主軸傳動。
    （四）夾具設計
     在前述定位基準面選擇的前提下，用擺動式壓板杠桿夾緊結構，夾緊力經驗算可以保證。

Abstract

 (一)Combmtvin  drilling  machine  is a large combination machine it adept a dispose form. The form has a fixed fitture’s single working location combination.
This kind of combination machine fitture and working bench are all fixed. Powen-sliding plat makes advam cry mourent. The power box on the power sliding plat from made scatting movement.This comgination and agle in instuit and is comvenient in desxging making and operating .Acording to precision demerd it adopt a datum place fixed in side .It is lined light with après lump on the other lylinder side against the datum palne .Itcan read working prelistion indemard a wording to the datum plane. Bacause of it is high working precision in side besides it has a round hole in high precision in side. It has a threaceling hole on the ohassion.
It can make full use of the strulture charactlst of the work piece. To design two short round cancel in the round hole in the side. To limit three degrees .To design acutside cancel on the bassface the battom. To limit one free degree. To limit three free degree one the deofimtine datum plane.It definet up a ccnrately and it’s fixture power is depene.
 (二)To desing the combination machine body-therr draning and one carcl that is ① the working orther draning of the working spares . it’s the major basis of the combination maching body. It’s a important paper in making using excmining and rensing maching .②To draw working schematw. Drawing  it’s for design a cutting tool. Assist tool afixture a multiple axle box hydravlive,pressure and a deetric capacity derise and important first hand date of the natirrad. Pants chovced and it’s a rewse machine kinf tool and the mgor basis for the test run.③ To draw the relation dimension drawing the relation dimension drawing is to impress the matual .assembly nelation  and the motin redation of the each form spanes of the machine.in order to enamine the relative .Pustion of all the machine spares and if the dimersion nelational .Spares is fix ,in the disigerents of dere loping the main axle box fixtrer’s special purpose pats.④Todesign the machin productirilg planning card .It’swod to report the working process of the machine to finish the need tine the cutting capacity the machine producticity and machine’s rate for the cach activity.
 (三)To design the comuination machine main axle box .To design it a cocording to the special cemoncl.It’s made up of the mational pants.As magin use is to arrange the position of all the mational axle box and transrnit the power and the motion to all the main axle by the electrical machinery or the power pants .According to the working demands of the worked pants and make it taget the demand transpont speed.The machine main axle is mode in side 400*400. It’sdraved by the mediwm drive.
 (四)To desing the fixture
 First to choice the forer word fixed position datum plane.It’s fixed by swing depressor fixtume structure the despower can be assured by checking computations.
