《过盈螺纹丝锥》部标准编制组在对过盈螺纹丝锥的设计、制造及使用情况的调研中,发现有的单位没有按标准要求保持AG过盈螺纹的配合紧度,他们在螺纹加工出来后,没有用量规检查螺纹中径的极限尺寸和分组尺寸;螺桩组合时也未使用限力扳手。这样,对于保证产品质量是有问题的。由于AG过盈螺纹在航空产品上应用比较广泛,很多受力较大的主要零部件都靠它起连接作用。所以,对于按标准规定保持应有的配合紧度的问题,应予以足够重视。 In the investigation of the design, manufacture and use of the interference thread tap, the unit in the “Compilation Thread Taps” Department found that some units did not maintain the tightness of the AG interference thread according to the standard requirements and they were processed by the thread After that, there was no gauge to check the limit size and group size of the thread diameter; the limit wrench was also not used in the screw pile combination. In this way, there is a problem with ensuring product quality. As the AG interference thread in the aviation products more widely used, many of the major components of the larger forces rely on it to play the role of connection. Therefore, due regard to the standard should maintain the tight fit should be paid enough attention.
