              斜墊鐵檢驗時工件毛刺用挫刀修去

              斜墊鐵檢驗時先將工件毛刺用挫刀修去:

                    斜墊鐵用平臺和百分表檢驗兩相對平面的乎行度,將工件乎放在平臺上,百分表架在斜墊鐵上左右移動,就可檢驗兩相對平面的平行度。檢查兩乎面的垂直度,可用直角尺,看其透光是否均勻。檢驗時,須先將工件各接邊的毛刺用挫刀修去,而日委確定一個面作為檢查基準面。

                    斜墊鐵兩相對平面間的平行度可用外卡鉗檢查。檢查時將卡腳張開,先以一個卡腳接觸工件一面,然后再使另一十腳與工件另一面擺動接觸,接觸工件兩面的松緊程度要憑感覺來決定,要不緊不松??ㄐ卦诳üぜr不能傾斜,并按照圖中細直線檢驗各處的松緊程度是否一致,若是一致的,就說明列頂是平行的。有時會發現1、2點的松一樣而3、4兩點又另一樣,假如2、4點都很緊,就說明3、4點的尺寸比1、2點的大,兩面不平行。如果l、3兩點的松紫—樣,而2、4兩點與1、3兩點不一樣,也說明兩面不平行。
