Description
Technical field
The present invention relates to a kind of external screw thread Special gauge, especially a kind of have multinomial qualitative detection function external screw thread Special gauge and detection method, belong to thread measurement specific purpose tool technical field.
Background technology
Existing English, made in U.S.A or metric thread quantitatively accurate detection can be realized by measurers such as slide gauge, thread gage and plug thread gauges, although this kind of measurer accuracy of detection is higher, but when being used for detecting English, U.S. standard screw thread, need metric length unit conversion Cheng Ying, long measure made in U.S.A, cumbersome. If measuring with ordinary steel ruler, both not accurate enough, it is also required to conversion equally, therefore also directly perceived not. Above measurer and detection method cannot be carried out quick detection, and efficiency is comparatively low.
By metric system and English from a pile metric system English, the bolt of mixing made in U.S.A, plug screw, made in U.S.A carry out fast grouping, and to distinguish different specifications, troublesome with the detection of existing measurer, need to measure externally threaded external diameter, pitch (or per inch tooth number) and thread form angle respectively, major diameter of thread also needs to be converted into inch from millimeter, both loaded down with trivial details not directly perceived yet, and require that operator have higher proficiency level.
