【正文】 主軸和傳動軸裝配表把多軸箱中每根軸（主軸、傳動軸、油泵軸）上齒輪套等基本零件的型號規(guī)格、尺寸參數(shù)和數(shù)量及標(biāo)準(zhǔn)件、外購件等，按軸號配套，用裝配表表示。這樣使圖表對照清晰易看，節(jié)省設(shè)計時間，方便裝配。（4）多軸箱技術(shù)條件 多軸箱總圖上應(yīng)注明多軸箱部裝要求。即： 1）多軸箱制造和驗收技術(shù)條件：多軸箱按ZBJ5801189《組合機床多軸箱制造技術(shù)條件》進行制造，按ZBJ5801289《組合機床多軸箱驗收技術(shù)條件》進行驗收。 2）主軸精度：按JB304382《組合機床多軸箱精度》標(biāo)準(zhǔn)（詳見《組合機床設(shè)計簡明手冊》P148表712）進行驗收。多軸箱零件設(shè)計 多軸箱總圖設(shè)計中，大多數(shù)零件是選用通用件、標(biāo)準(zhǔn)件和外購件；對于變位齒輪、專用軸等零件，則應(yīng)設(shè)計零件圖；對于多軸箱體類通用件，必須繪制補充加工圖。 （1）專用零件工作圖 如變位齒輪、專用軸和套等零件，可按一般零件工作圖規(guī)定。參照同類通用零件圖，結(jié)合專用要求設(shè)計繪圖。 （2）補充加工圖 多軸箱體、前蓋、后蓋等通用零件，應(yīng)根據(jù)多軸箱總圖要求，繪制出需補充加工的部位，（如多軸箱體主軸承孔、傳動軸承孔、油泵及其軸孔，定位銷孔、后蓋窗口擴大部位結(jié)構(gòu)等），通常習(xí)慣用粗實線畫出補充加工部位的結(jié)構(gòu)，其尺寸、形位公差、表面粗糙度等均按機械制圖國際規(guī)定格式標(biāo)記；通用鑄件的原有部分的輪廓等一律用細(xì)實線表示。結(jié) 論本次畢業(yè)設(shè)計是468Q發(fā)動機缸體雙面臥式組合機床及左主軸箱設(shè)計。通過此次設(shè)計，了解了468Q發(fā)動機的工作原理和加工工藝。設(shè)計過程中參觀了太原第一機床廠，了解了組合機床的設(shè)計。本次設(shè)計任務(wù)量大、難度大，但在老師的指導(dǎo)下，設(shè)計者順利完成了本次設(shè)計。本次設(shè)計的重點和難點是主軸箱的設(shè)計，比較突出的是軸和齒輪的選擇，所以重點對軸和齒輪進行了校核。這次設(shè)計是對大學(xué)四年所學(xué)專業(yè)知識的一次總結(jié)，并得到了一些見解和收獲，對以后的工作和學(xué)習(xí)產(chǎn)生了深遠(yuǎn)的影響。感謝指導(dǎo)老師對我的指導(dǎo)和關(guān)心，使我得以順利完成畢業(yè)任務(wù)。由于本人理論基礎(chǔ)和實踐水平有限，錯誤在所難免，希望老師和同學(xué)諒解并指正。外文資料The aggregate machinetool CAD system development and research abstract aggregate machinetool CAD is in Window 95/98, Wndows under the environment, designs personnel39。s specialpurpose CAD system with and the AutoCAD R14 ADS/ARX technology development face the aggregate software technological advance, performance reliable, function strong, convenient practical, has provided the modernized design tool for our country aggregate machinetool profession.　Key word: Aggregate machinetool CAD jig CAD multiaxlebox CAD1 uses the aggregate machinetool CAD technology imperative　The aggregate machinetool is with according to serialized, the standardized design general part and the special purpose machine which poses according to the work piece shape and the processing technological requirement design specialpurpose part, belongs to the disposable design, the disposable manufacture piecework , the design quantity is big, the design work is the current petition intense market economy, the user to the engine bed technical sophistication, the quality reliability as well as the goods supply cycle all requests very high, but guaranteed these many factors the key is the design. In the past that backward manual design method has not been able to satisfy the product design the request, uses the CAD technology, throws off the chart board, has bee the current technological revolution the tidal current, imperative.2 aggregate machinetool CAD the application present situation Overseas aggregate machinetool CAD technology research starts the parison the beginning of the 7039。s, some industry developed country first starts in the multiaxlebox CAD aspect to study. Has entered since in particular for the 9039。s, along with the puter technology development, the interactive cartography and the database management system and so on the development and the application, causes the aggregate machinetool CAD technology day by day practical also the use scope expands unceasingly, the developed country has used the CAD technology generally in the aggregate machinetool present, to CAD/CAM integrative system development. In recent years, according to us to American several main engine bed factories (BURGMAST, KINGSBURY, panies and so on INGERSOLL LAMB, CINCINNATI, MILACRON, CROSS) the understanding, its CAD technology obtained the universal application. In which most noticeable is INGERSOLL Corporation has 50 interactive CAD workstation position software and hardware environment, caused it to realize nearly 100% CAD. On the domestic machine tool design portfolio using CAD understanding earlier. The beginning of the 1970s, Dalian Machine Tool Institute portfolio started on the research in this area of work. 1978 state as a bination of mechanical CAD machine industrial projects, and instructed the Shanghai Jiaotong University. Dalian Machine Tool Institute portfolio, a ministry official in charge of the Institute of Automation, Dalian Polytechnic University, Qinghua University, Beijing University of Technology, Shanghai Institute of mechanical and electrical products and other units to participate in the drilling machine CAD bination of research, This raised our portfolio Machine CAD technology in the district. After 10 years of efforts and achieved initial results. However, the bination of machine CAD system is 1227 in VAX II and Micro VAX II on the development, hardware investment, which is difficult to use. By the time the hardware and software environment for the restrictions, narrow scope of application software, users inconvenient.3 Development portfolio dedicated machine CAD system software CAD technology is the contemporary electronic information technology an important ponent of , CAD technology to be mercialized as the most important hightech industries. The supporting software and hardware, on the basis of different industries, different professions secondary development software, developed for the industry, The dedicated professional mercial software can not only make good economic returns, but will make significant social benefits. Ninth FiveYear Plan period state auto industry as a pillar industry of the national economy, for the industry to provide a bination of technologies and equipment to machine tool industry to develop rapidly. Along with the development of the auto industry, machine designed to enhance portfolio quality, shorten the design cycle has bee an extremely urgent task. Combined Machine CAD technology and can shorten the design cycle and improve design quality, enterprises in the sector improve its petitive edge, enterprises will bring about significant economic benefits. Dalian is China39。s important industrial base, as a bination of Machine Tool Industry Technology and Development Center in Dalian Machine Tool Institute portfolio, industry should play the leading role for the realization of design automation, enhance technological innovation and product petitiveness. promoting our portfolio machine d
