正交孔中心线不相交允差的检测

Test Non-intersecting Tolerance of the Centre Line of Perpendicular Hole

介绍了鸡西煤矿机械有限公司生产的BM0101轴向柱塞泵的工作原理,泵壳的2-80H7孔中心线与55H7中心线不相交允差为0.02 mm,对这一技术要求测量不准确的后果进行了阐述,对自制的检测量具和使用方法进行了说明。

BM0101Axial plunger pump principle and 2 - φ80H7 hole center line of shell pumps are produced by Jixi coal mining machinery co. , ltd, which tolerance does not intersect 0.02mm by φ55H7 centedine. The inaccurate consequence with measuring technical requirements is explained, homemade detection tools and using methods are noted.
