Abstract

The invention provides a cable bending radius measurer and a detection method. The cable bending radius measurer comprises a fixation support, a telescopic calibrated scale and a rotating shaft. The rotating shaft enables the fixation support and the telescopic calibrated scale to be fixed together; and the fixation support and the telescopic calibrated scale can rotate around the rotating shaft.The telescopic calibrated scale comprises three hollow square cubes, that is, an upper calibrated scale, a middle calibrated scale and a lower calibrated scale respectively, wherein the upper calibrated scale, the middle calibrated scale and the lower calibrated scale are progressively increased in external diameter; the upper calibrated scale can be withdrawn into the middle calibrated scale, andthe middle calibrated scale can be withdrawn into the lower calibrated scale; and the upper calibrated scale, the middle calibrated scale and the lower calibrated scale are respectively marked with scale lines. The cable bending radius measurer and the detection method enable detection of cable bending radius to be simple and easy to carry out; the method can visually and accurately detect whether the cable bending radius meets design requirements, thereby improving cable bending radius detection accuracy and improving detection efficiency of the cable bending radius; and the cable bending radius measurer and the detection method can be well suitable for detection of various cable bending radiuses.

Description

technical field [0001] The invention belongs to the technical field of aircraft assembly, and in particular relates to a cable bending radius measuring device and a detection method. Background technique [0002] Today, with the rapid development of the aerospace industry, the reliability of the quality of aircraft cable laying is an important indicator parameter affecting the safety performance of the aircraft. Controlling the bending radius of the cable during the cable laying process is an important parameter to ensure the safe use of the cable. The aircraft is a high-speed, high-vibration whole. Sufficient cable bending radius is an important guarantee to ensure that the cables are not subject to vibration stress during the flight of the aircraft. The existing measurement technology at this stage is to use a vernier caliper to measure the bending radius of the cable, but due to the structural limitations of the vernier caliper, the center of the arc where the cable is be...
