Description

Technical Field

[0001] The utility model relates to the technical field of bolt axial force detection, in particular to an intelligent detection device for the axial force of a high-strength bolt. Background Art

[0002] The intelligent detection device for high-strength bolt axial force is an advanced device specially used to detect the axial force of high-strength bolts. It uses a force sensor connected in series with a high-strength bolt connection pair to measure the axial force on the strain tube with a resistance strain gauge attached through the connection thread. When the strain tube is subjected to axial tensile load, the resistance value of the resistance strain gauge will increase, resulting in an unbalanced bridge circuit.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN217466529U discloses a multifunctional high-strength bolt automatic detector, including a frame, on which are provided a bolt clamp, a torsion shear body and a driving mechanism for transmitting power to the torsion shear body, an inner turntable and an outer turntable are provided at the output end of the torsion shear body, the outer turntable is detachably provided with an outer sleeve, the inner turntable is detachably provided with an inner sleeve, and the outer turntable is provided with a clamping piece that can limit the rotation of the outer turntable.

[0004] The above-mentioned automatic detection instrument drives the inner and outer sleeves to torsion shear type high-strength bolts through the torsion shear body, and can also drive the inner sleeve to tighten the large hexagonal high-strength bolts after the clamping part limits the rotation of the outer turntable, and measure the axial force and torsion at the same time. The instrument automatically calculates the torque coefficient to ensure the normal detection of the two types of bolts; however, before the detection, when fixing the bolts, the first fixing plate and the second fixing plate need to be completely removed to install the bolts, and during the installation process, the first fixing plate and the second fixing plate need to be supported, which is cumbersome in actual operation and affects the efficiency of bolt detection.

[0005] Therefore, the utility model provides a high-strength bolt axial force intelligent detection device to solve the above problems. Utility Model Content
