contact surfaces. 畫各零件的細(xì)小結(jié)構(gòu),完 成全部圖形。 5) Draw the dimension boundaries, dimension lines, and number leaders, and plete the entire drawing. 畫尺寸界線 、 尺寸線 、 序號指引線等。 ( 明細(xì) 欄) (標(biāo)題欄) 技術(shù)要求 ( ……) 請點擊鼠標(biāo)左鍵顯示后面內(nèi)容 Exercises 練習(xí)題 1. Build up a sectional assembly drawing of the ponent parts looking on the cutting plane A— A by tracing over and correctly positioning each part (obtain sizes by measuring the drawing and retain the integer, scale 1:1). 畫出帶輪機(jī)構(gòu)的 A— A剖視裝配圖(尺寸數(shù)值由圖中 測量,取整數(shù),比例 1:1)。 3. Draw an assembly drawing of flat nose pliers on A2 sheet (scale 1:1). 在 A2圖紙上,按 1?1的比例拼畫平口鉗裝配圖。 (2) Working principle and transmission route 工作原理與傳動路線 Turn the screw with the handle to drive the nut and to make the movable body of the clamp to perform rectilinear movements along the fixed body of the clamp. This will make the mouth of the clamp open or close to clamp or unload the part. 用手柄轉(zhuǎn)動螺桿,使螺桿帶動螺母,進(jìn)而帶動活動鉗身沿著固定鉗身 作直線運(yùn)動,從而使鉗口張開或閉合,即可夾緊或卸下零件。螺母與活動鉗身用螺 釘連成一體,螺母下方凸出的臺階與固定鉗身接觸,當(dāng)螺桿轉(zhuǎn)動時,螺母只作 直線運(yùn)動,不作旋轉(zhuǎn)運(yùn)動。螺桿左端 有一個環(huán)用銷釘與螺桿固定
