【正文】 定其表達(dá)方案 Analyze what type the part belongs to 分析屬哪類零件 Determine the projection direction of the front view 確定主視圖觀察方向 Determine how many views are needed (Where to use section or cut view ) 需用幾個(gè)視圖表達(dá) (何處用剖視或斷面圖 ) 請(qǐng)點(diǎn)擊鼠標(biāo)左鍵顯示后面內(nèi)容 Detail drawings from assembly drawings 由裝配圖拆畫零件圖 (4) Dimensioning and tolerance 標(biāo)注尺寸及公差 1) Dimensions not marked in the assembly drawing should be measured for calculation (round off to integers). 裝配圖中 未注的尺寸 , 應(yīng)量取后根據(jù)圖上的比例換算求得 (取整數(shù) )。 根據(jù)零件名稱和明細(xì)欄 找出 其在圖中的 位置 ； 2) Separate the part from others, according to the consistence of the section line in each view。 2. Analyzing views 分析視圖 Methods and Steps 讀圖的方法和步驟 請(qǐng)點(diǎn)擊鼠標(biāo)左鍵顯示后面內(nèi)容 By bining dimensioning and technical requirements, further analyze the structure, transmission relations and working principles, create an image of the assembly structure. 在以上各步驟的基礎(chǔ)上，結(jié)合尺寸標(biāo)注及技術(shù)要求等有關(guān)內(nèi)容，進(jìn)一步綜合分析總體結(jié)構(gòu)、傳動(dòng)關(guān)系和工作原理，通過歸納總結(jié)，想象出裝配體的總體結(jié)構(gòu)形狀。 4） Analyze the structure and dimension of each part or subassembly. 分析零、部件的結(jié)構(gòu)及尺寸。 2） Start from the view representing the movement relationship. 從表達(dá)運(yùn)動(dòng)關(guān)系的視圖入手。 Let us take the ball valve in Fig. 92 for example to explain the methods and steps for reading and interpreting an assembly drawing. 現(xiàn)以“球閥”為例，說明讀裝配圖的方法和步驟。 Interpreting and Separating Assembly Drawings 讀裝配圖和由裝配圖拆畫零件圖 Objectives and requirements 讀圖的目的和要求 Methods and steps 讀圖的方法和步驟 Detail drawings from assembly drawings 由裝配圖拆畫零件圖 Exercises 練習(xí)題 請(qǐng)點(diǎn)擊相應(yīng)標(biāo)題顯示其內(nèi)容 2) Clarify the purpose, the relative position, the fitting relationship of
