DEVICE AND METHOD FOR MEASURING BENDING ANGLE OF BENDING PIECE

摘要

A device for measuring the bending angle of a bending piece is composed of a rotating platform (100), a drive device (400) mechanically connected with the rotating platform (100) to drive the rotating platform (100) to rotate, an angle measuring device (200) for measuring the angle of rotation of the rotating platform (100), a distance measuring device (300) fixed on the rotating platform (100) to measure the distance between the distance measuring device (300) and the first bending part (30a) of the bending piece, and a control device (500) electrically connected with the angle measuring device (200), the distance measuring device (300) and the drive device (400). According to the distance between the distance measuring device (300) and the first bending part (30a), the control device (500) can control the drive device (400) to drive the rotating platform (100) to rotate in the bending direction of the first bending part (30a), until the distance between the rotating platform and the first bending part (30a) measured by the distance measuring device (300) is minimal, then the bending angle of the bending piece can be calculated based on the angle of rotation measured by the angle measuring device (200) at this point. A method for measuring the bending angle of a bending piece is also disclosed. The device and method has the advantages of simple structure, accurate measurement and lower demand for the external environment.
