Three-dimensional postweld weld stress processing system based on machine vision

Abstract

The invention discloses a three-dimensional postweld weld stress processing system based on machine vision. The three-dimensional postweld weld stress processing system is constituted by a driving mechanism, a crosshead shoe, a rotating mechanism, and a double-camera acquisition device. A stepping motor is used to drive the crosshead shoe to carry out postweld weld precision positioning, and a servo direct current motor is used to control moving of a robot body. The rotating mechanism is cooperated with the crosshead shot to realize three-dimensional motion. The driving mechanism, the crosshead shot, the rotating mechanism, and the double-camera acquisition device are cooperated with each other to realize accurate tracking and stress processing of an ultrasonic impact gun in three-dimensional space. The three-dimensional postweld weld stress processing system is used to effectively solve problems of conventional postweld processing ways such as low precision, low efficiency, and inability of realizing multi-directional weld processing, and is used to improve the quality of the postweld weld.

Description

technical field [0001] The invention relates to a three-dimensional post-weld weld stress processing system based on machine vision, in particular to a three-dimensional tracking and stress processing technology based on a dual camera module. Background technique [0002] In modern welding engineering, manual processing of welds means that workers can understand the actual weld position through eye observation and timely adjust the position, attitude and speed of the post-weld processing machine to adapt to changes in the weld trajectory; post-weld manual detection is the use of Tools such as gauges, rulers, and low-magnification magnifying glasses are used to inspect the welding condition with the naked eye, so as to judge the effect of weld seam treatment. This method requires high manpower, low safety, low detection accuracy, and takes a long time. The detection results depend on human subjective judgment, which reduces production efficiency and increases the number of su...
