Embodiment Construction

[0009] This patent is only applicable to the measurement of the coaxiality of two internally threaded holes with different directions of rotation, and conventional thread plug gauges are used for accurate thread measurement. This article takes the coaxiality measurement of the parts with M12×1.5LH-5H6H and M12×1.5-5H6H two threaded holes requiring a coaxiality of 0.1 as an example to illustrate.

[0010] A gauge used to detect the coaxiality of two internal threads with different directions of rotation, the structure is as follows figure 1 As shown, it includes thread gauge Ⅰ1, thread gauge Ⅱ2 and pin 3, wherein the left-handed thread of thread gauge Ⅰ1 matches the left-handed thread of the part to be tested Ⅰ4, and the right-handed thread of thread gauge Ⅱ2 matches with the part to be tested Ⅱ5. The right-handed thread cooperates and plays a positioning role together. The φ6 axis on the pin 3 is matched with the φ6 holes on the thread gauge I1 and the thread gauge II2 as the...

Abstract

The invention relates to a gauge for detecting the coaxiality of two internal threads with different rotation directions and a detection method thereof. The gauge includes two thread gauges I, thread gauge II and pins with different rotation directions. The thread gauge I matches the thread of the part I to be measured, and the thread gauge II matches the thread of the part II to be measured. , The φ6 axis on the pin is matched with the φ6 holes on the thread gauge head I and thread gauge II, as the measuring part. The steps of using the aforementioned gauge to detect the concentricity of two internal threads with different directions of rotation are as follows: holding the handle, screw the thread gauge Ⅰ and thread gauge Ⅱ into the threads of the part to be tested Ⅰ and part Ⅱ from both sides respectively. hole, and then insert the pin into the hole of thread gauge I and thread gauge II, if it is fully inserted, the coaxiality is consistent, otherwise, the coaxiality is not consistent. The device and method have the advantages of simple operation, convenience and practicality.
