Plate bending angle detection device and method

Abstract

The invention discloses a plate bending angle detection device and method. A plate is provided with a first part and a second part which form a bending angle. The device comprises a scanner and a processor, wherein the scanner is used for emitting beams to the plate and generating a detection signal comprising beam lengths and emitting angles corresponding to a plurality of points on the first part of the plate and beam lengths and emitting angles corresponding to a plurality of points on the second part of the plate; the processor is used for determining a linear equation of the first part and a linear equation of the second part according to the detection signal and calculating the bending angle of the plate according to the linear equation of the first part and the linear equation of the second part. Therefore, the bending angle can be detected in real time in the plate processing process. The plate bending angle detection device and method improve production efficiency and measurement efficiency, are high in automation degree and free of manual intervention, and reduce labor force.

Description

technical field [0001] The invention relates to the detection field, in particular to a device and method for detecting a bending angle of a plate. Background technique [0002] In the field of construction machinery, the quality of the crane boom is directly related to the overall performance of the crane, and the cross-sectional shape of the boom is the main factor affecting the bearing capacity of the boom. In the boom forming manufacturing process, the angle control of its bending parts is very important to the processing technology. [0003] There are many ways to measure the angle of bending parts, common ones are manual measurement, mechanical measurement and so on. The measurement accuracy of the manual measurement method is not high, and the reading depends on the human eye. There are cases of misreading by the operator, and to a certain extent, it affects the working efficiency of the bending machine. Mechanical measurement methods are widely used, with the advan...

The measurement accuracy of the manual measurement method is not high, the reading depends on the human eye, there are cases of misreading by the operator, and to a certain extent affects the working efficiency of the bending machine

Mechanical measurement methods are widely used, with the advantages of simplicity and low cost, but the equipment is bulky, the measurement accuracy is not high enough, and the measurement delay is large. In most cases, dynamic measurement cannot be realized, and non-contact measurement cannot be implemented.
