Abstract

The invention discloses a thread testing process device, which is provided with two sleeves. A bolt to be tested penetrates through the center holes of the two sleeves. A nut is arranged in one sleeve and is screwed with the bolt to be tested. Two testing chucks are respectively arranged on the two sleeves. One end of each testing chuck is in threaded fit with the inner wall of the sleeve and the other end of the testing chuck is clamped by a jaw of a universal mechanical tester. By adopting the technical scheme, since the testing chucks are in threaded connection with the sleeves, the structure is compact and the device is convenient to manufacture; the universality is higher and the device is suitable for mass production; a series of tooling can be manufactured according to the specifications of nuts to be tested to meet testing requirements; and the strength of the testing chucks and the sleeves can be easily guaranteed and the service life of the tooling is longer.

Description

technical field [0001] The invention belongs to the technical field of mechanical parts testing, and relates to the testing technology of threaded parts. More specifically, the invention relates to two kinds of thread testing process devices. In addition, the present invention also relates to the test methods adopted by the two screw thread test process devices. Background technique [0002] In the prior art, there is no corresponding test equipment for testing the mechanical properties of threads, and only the chemical composition of bolts and nuts can be tested. Its disadvantages are: [0003] 1. The chemical composition of the test material needs to prepare a large amount of chemical reagents each time, so the test cycle is relatively long and the cost is relatively high. [0004] 2. Mechanical properties are important parameters for judging whether bolts and nuts are qualified. Materials with the same chemical composition have great differences in mechanical properties...
