Description

Technical Field

[0001] The utility model relates to the technical field of torsion spring detection, in particular to a large-diameter torsion spring load detection device. Background Art

[0002] Torsion springs are coil springs. The ends of a torsion spring are fixed to other components, and when the other components rotate about the center of the spring, the spring pulls them back to their original position, creating a torque or rotational force.

[0003] After torsion springs are manufactured, they need to be tested for various properties, such as load tests at specified heights, permanent deformation tests, and fatigue life tests. Torsion springs need to pass rigorous tests before they can be put into use, because some torsion springs are used in more important occasions and have strict requirements for each product used, such as vehicles and large equipment. If the torsion spring requirements are not met, it is easy to cause major accidents during use.

[0004] However, for torsion springs with larger wire diameters, especially those made of higher strength materials such as square steel, it is difficult to fix and test them with general torsion spring testing tools, and special equipment is needed to fix them before further load testing can be performed.

[0005] Therefore, it is necessary to design a detection tool specifically for large-diameter torsion springs. There is currently a torsion spring detection tool with Chinese patent publication number CN219455430U, which uses a positioning piece to fix the torsion spring, and fixes the fixed arm of the torsion spring through a fixed structure, and connects the inspected arm of the torsion spring through a detection structure. While preventing the torsion spring from stretching itself, it can achieve corresponding load detection on the large-diameter torsion spring.

[0006] However, since the positioning member of the device is a constant rod-shaped structure, the applicable wire diameter spring is relatively single and the practicability is insufficient. Utility Model Content
