钢丝螺套工具的选用

 钢丝螺套工具的选用： 丝锥： 从附表中的8、9、10、11、12列中选用 。为了便于合理地选择及正确使 用，请参考原文第18页—“盲孔或通孔的机械或手工攻制。” 量规： 从附表中的第13、14、15列选用。一般提供二种配合精度的量规 。建议 装入螺套前先用量规测量螺纹孔尺寸。 旋入工具： 从附表中的第16列选用。请注意，细牙螺套旋入工具的芯轴上带有螺纹， 这样可避免当螺套旋入时产生错牙。粗牙螺套旋入工具的芯轴不带螺纹。 安装柄折断工具： 从附表中的第17列选用。请注意：安装柄折断工具可通用。 螺套旋出工具： 从附表中第18列选用。四种规格的工具可满足所有规格尺寸的螺套需要。 气动旋入工具： 从附图中第20页说明。满足长度规格不大于2D的螺套使用 。工具配有定 位套。 螺丝公称螺套系尺寸 列 钢丝螺安装深度 钢丝螺套丝锥 套低孔钢丝螺套工作塞规 塞规 安装工具 安装长度以名义直径的倍数表示 1d 1.5d 2d 2.5d 3d 9 10 11 -
