Description

technical field [0001] The invention relates to the technical field of curvature measurement of a curved F-shaped rail, in particular to a two-dimensional measuring device and a detection method for the curvature of a maglev curved F-shaped rail. Background technique [0002] In the processing of curved F-rail of medium and low-speed maglev track, the curvature (or linear) control of curved F-rail is the difficulty and focus in the processing of curved F-rail, so the detection of the curvature of curved F-rail is particularly important. [0003] At present, the most commonly used method is to calculate the curvature or curve radius by measuring the chord height with a flat ruler or stretched wire. The measurement accuracy is low, and it can only meet the inspection requirements of rough bending, and cannot guarantee the measurement accuracy requirements of the finished product after F-rail processing. . [0004] Three-dimensional laser measurement technology can also be use...
