4樓正解,! |
4樓說的比較明白,,我理解的是:第一個是3/16”的沉頭通孔((比M4大一點,),,沉頭角度是82°,,裝的時候用#8的螺釘,有14處,; 第二個估計在其他視圖,,要是沒其他視圖,你可以按比例自己算一下,, |
The first picture: Drill a 3/16” through hole, tap the countersunk head angle of 82°, thread specification 8#, deep penetration threaded holes, a total of 14 places; The second picture: the depth of the threaded hole in the planing surface is 0.103,。 |
Very simple, easy understand from the drawings. |
第一個圖的意思是鉆3/16”通孔,攻沉頭角度82° 8#貫穿螺紋 14處 第二個圖孔的直徑應(yīng)該是標注在圖紙其他同樣的孔處 個人愚見 如有誤請大神指教 |
局部視圖大家都懶得猜了 |
