Abstract

The invention provides a device and method for measuring the bending angle of a bent piece. The device comprises a rotation platform, a drive device, an angle sensor, a ranging sensor and a control device, wherein the drive device is mechanically connected with the rotation platform and used for driving the rotation platform to rotate; the angle sensor is used for measuring the rotation angle of the rotation platform; the ranging sensor is fixed on the rotation platform and is used for measuring the distance between the ranging sensor and a first bent part of the bent piece; and the control device is electrically connected with the angle sensor, the ranging sensor and the drive device, and is used for controlling the drive device to drive the rotation platform to rotate in the bending direction of the first bent part according to the distance between the ranging sensor and the first bent part until the distance to the first bent part measured by the ranging sensor is minimal, and at least calculating the bending angle of the bent piece according to the rotation angle sensed by the angle sensor. The device and method provided by the invention have the advantages of simple structureand accurate measurement, and have low requirements for 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...
