Abstract

The invention provides a double-beam laser welding bulkhead inclination angle measuring device and method, the device comprises laser line structure light sources and industrial cameras, the laser line structure light sources and the industrial cameras are arranged side by side on the side of T-shaped joints, and the industrial cameras collect T-shaped joint areas irradiated by the laser line structure light sources; wherein the two groups of laser line structure light sources and the two groups of industrial cameras are symmetrically arranged on the two sides of a bulkhead of the T-shaped joints, and are connected to a mechanical arm of the robot; and the device also comprises an industrial personal computer in signal connection with the laser line structure light sources and the industrial cameras. Double-side laser line structured light is adopted to scan a T-shaped joint abutted seam, the industrial cameras are used for collecting scanning images, the included angle between a bulkhead and a skin is accurately measured, and whether the inclination angle of the bulkhead is qualified or not is judged by obtaining position coordinates of the robot and automatically comparing a measurement result with a part mathematical model; and whether the deformation of parts is qualified can be judged.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a device and method for measuring the inclination angle of a double-beam laser welding frame. Background technique [0002] Due to its excellent structural stability and lightweight advantages, the ribbed panel structure has been widely used in the skin structure of aircraft, rockets and other aircraft. At present, the advanced manufacturing method of titanium alloy thin-walled ribbed panels is to use hot forming to form the required profile, and use double-beam laser welding to weld the reinforcing ribs and skin together. In the process of using laser welding to manufacture ribbed panels, the assembly deformation of the welding frame is the main problem affecting its manufacturing accuracy. The inclination of the T-joint frame after laser welding has a great impact on the structural strength and the gap between the frames in the subsequent final assembly. The connecti...
