Welding position control system of welding gun

Abstract

The invention provides a welding position control system of a welding gun. The system comprises a welding gun tracking module, which is used for tracking the position of the welding gun in real time through a preset laser tracking device to acquire spatial position information of the welding gun; a welding tracking module, which is used for acquiring a welding image in real time through a preset snapshot camera and tracking welding seam information and welding spot information in real time based on the welding image; a simulation module, which is used for constructing a simulation scene model based on the spatial position information of the welding gun, the welding seam information and the welding spot information; and a regulation and control module, which is used for regulating and controlling the position of the welding gun so that the welding gun can conduct welding at the corresponding welding spot position according to the simulation scene model. The system has the beneficial effects that welding information can be comprehensively controlled through welding seam data collection and welding gun data collection, then the spatial information of the welding information is determined by constructing the simulation scene model based on the comprehensive control over the welding information, and finally the spatial regulation and control of the welding spot position are realized based on the simulation scene model.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding position control system of a welding torch. Background technique [0002] At present, the automatic welding of large steel structural parts is done by welding torches. In this welding process, the welding torch needs to increase the swing to achieve multi-layer and multi-pass welding, improve the edge formation of the molten pool, and eliminate the "undercut" defect. , Improve the quality of the weld and enhance the appearance of the weld bead. At the same time, in order to adapt to the welding process of different welds, the welding torch posture, swing frequency, swing amplitude and left and right dwell time all need to be adjusted. [0003] In the multi-layer and multi-pass welding process of large steel structure parts, the welding process of each weld seam is different, and the welding torch posture and swing parameters need to be adjusted. In the existing weldin...
