箱体的特性 箱体是各机构的主要零件,它能保证其他零件的 正确位置和相互作用。 对箱体的主要要求是:①轴孔精度按尺寸和形状均应在OCT第3～1级范围内;②在两侧或数侧体壁上孔的同心性;③各中心线之间及其对各基面间的平行性和垂直性;④各孔中心线之间与基面间距离的精度;⑤端
The characteristics of the box Cabinet is the main parts of the institutions, it can guarantee the correct position and interaction of other parts. The main requirements of the box are: ① axial hole accuracy by size and shape should be within the OCT level 3 ~ 1; ② concentricity of holes on both sides or on the side wall; ③ between the center line and Its parallelism and perpendicularity between each base surface; ④ each hole centerline between the accuracy of the distance between the base surface; ⑤ end
