Abstract

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.

Description

technical field [0001] The invention relates to the field of angle measurement, and in particular to a measuring device and method for detecting the bending angle of a bent workpiece. Background technique [0002] The busbar bending machine is a kind of equipment used to process the busbar. figure 1 The application of angle control in busbar bending machine is shown. Such as figure 1 As shown, the busbar bending machine includes a die 10 and a pressure head 20 . When using the busbar bending machine to change the bending angle of the busbar 30, the busbar 30 is placed in the die 10, and the punch 20 is used to stamp the busbar 30, thereby changing the bending angle of the busbar 30. In this busbar bending machine, the control of the bending angle is realized through the angle indicating device. The angle indicating device includes a push rod 40, a pointer 50 and a dial 60. The push rod 40 is located in the die 10, connected with the pointer 50, and moves downward with th...
