Embodiment Construction

[0057] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] see Figure 1 to Figure 4 and Figure 10 , as a specific embodiment of the bolt torque detection device of the present invention, it includes a sleeve 100 and a bolt clamping assembly 200 . Wherein, the sleeve 100 has an accommodating cavity 110 with one end open, which is suitable for covering on the bolt 300 to be tested. One end of the bolt clamping assembly 200 is disposed in the accommodating chamber 110 and is suitable for clamping the measured bolt 300 . The closed end of the sleeve 100 is provided with a fixing portion 120 . The fixing part 120 cooperates with a torque wrench.

[0059] It sets a bolt torque detection device used in conjunction with a torque wrench, and sets a bolt clamping assembly 200 in the housing chamber 110 of the sleeve ...

Abstract

The invention disclose a bolt torque detector which is used in cooperation with a torque wrench. The bolt torque detector comprises a sleeve and a bolt clamping assembly, the sleeve includes an accommodation cavity with an opening at one end, and can cover a detected bolt; one end of the bolt clamping assembly is arranged in the accommodation cavity, and used to clamp the detected bolt; and the enclosed end of the sleeve is provided with a fixation part, and the fixation part cooperates with the torque wrench. The detector fixes the detected bolt via the bolt clamping assembly, avoids the detected bolt from a welding process, does not influence the original tensile strength of the bolt, ensures the accuracy of a detection result, and effectively solves the problem that the detection result is low in accuracy traditionally due to the fact that the torque of the bolt is damaged.

Description

technical field [0001] The invention relates to the field of bolt testing, in particular to a bolt torque detection device. Background technique [0002] In order to test the reliability of the riveted product using the riveted bolt, the maximum ejection force and the maximum breaking torque of the riveted bolt on the product are usually tested. At present, when testing the breakage torque of riveted bolts, in order to prevent thread slippage between the nut and the screw, the nut and the screw part are usually welded first, and then the torque wrench is inserted into the nut to test the maximum breakage torque. However, when the nut and the screw part are welded, it is easy to melt the bolt part at high temperature, thereby weakening the original tensile strength of the bolt, so that the accuracy of the detection result of the breaking torque of the bolt is low. Contents of the invention [0003] Based on this, it is necessary to provide a bolt torque detection device ca...
