【正文】 工藝過程綜合卡片 1張） 3．繪制夾具裝配圖（ A0 或 A1） 1張 4．繪制夾具中 1個零件圖（ A1 或 A2。 1張 4．編寫課程設(shè)計說明書（約 6000—— 8000 字）。 3～ 7天，完成零件的工藝性分析 ,確定毛坯的類型、制造方法和機(jī)械加工工藝規(guī)程的設(shè)計并編制出零件的機(jī)械加工工藝卡片。 4．第 11～ 13 天，完成夾具總裝圖的繪制。 6．第 16～ 18 天，整理并完成設(shè)計說明書的編寫。 8．第 20～ 21 天，答辯。 這次設(shè)計的是 端蓋，有零件圖、毛坯圖、裝配圖各一張，機(jī)械加工工藝過程卡片 和與所設(shè)計夾具對應(yīng)那道工序的工序卡片各一張。了解了端蓋的作用，接下來根據(jù)零件的性質(zhì)和零件圖上各端面的粗糙度確定毛坯的尺寸和機(jī)械加工余量。 遼寧工程技術(shù)大學(xué)課程設(shè)計 5 Abstract Machinery Manufacturing Technology curriculum design is finished we learn all the basic course of the University, technology and the most basic course after the specialized, which is our graduation project before conducting the various courses of study by an in depth prehensive review of the total, is also a Theory with practical training, therefore, in our four years of university life occupy an important position. This is the cover design, parts map, rough map, one of the assembly, machining process with the card and the corresponding fixture designed by the procedures of the process of a card. First of all, we must familiar with the parts, the parts subject to the cover. Cover understanding of the role, followed in accordance with the nature of parts and ponents in the face of the map on the roughness of rough determine the size and mechanical Jiagongyuliang. According to another location and then we set the benchmark fine first base, established after the benchmark crude, finalizing the cover of the road map, the enactment of the workpiece clamping programme, to draw fixture assembly. 遼寧工程技術(shù)大學(xué)課程設(shè)計 6 目錄 端蓋的工藝分析及生產(chǎn)類型的確定 ................................................ 8 、端蓋的用途 ..................................................................... 8 、端蓋的技術(shù)要求 ............................................................... 8 、審查端蓋的工藝性 ............................................................ 9 、確定端蓋的生產(chǎn)類型 ......................................................... 9 確定毛胚、繪制毛胚簡圖 ...........................................................10 選擇毛胚 .........................................................................10 確定毛胚的尺寸公差和機(jī)械加工余量 ......................................10 公差等級 ................................................................. 10 . 2 端蓋鑄造毛坯尺寸工差及加工余量 ..................................10 繪制端蓋毛坯簡圖 ......................................................10 擬定端蓋工藝路線 ................................................................... 11 、定位基準(zhǔn)的選擇 .............................................................. 11 ．精基準(zhǔn)的選擇 ......................................................... 11 ．粗基準(zhǔn)的選擇 ......................................................... 11 、表面加工方法的確定 .......................................................12 、加工階段的劃分 ..............................................................12 、工序的集中與分散 ...........................................................13 、工序順序的安排 ..............................................................13 機(jī)械加工工序 ............................................................13 ．熱處理工序 ............................................................
