Abstract

The invention relates to a thin-wall structure laser welding system and method based on multi-robot collaboration. The thin-wall structure laser welding system based on multi-robot collaboration comprises two parallel guide rails. A welding robot for welding a wallboard part and an auxiliary robot for pressing the wallboard part are arranged on the two guide rails through external shafts respectively, a laser welding head is arranged on the welding robot, and the welding robot and the auxiliary robot have strokes for moving in the width direction of the guide rails through the external shafts respectively. A skin used for supporting the wallboard part is connected between the two guide rails, and a flexible tool used for adjusting and positioning the skin is arranged at the bottom of the skin. The invention belongs to the technical field of laser welding.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser welding system and method for thin-walled structures based on multi-robot collaboration. Background technique [0002] The use of laser welding technology to manufacture T-joints of aircraft fuselage panels is an advanced manufacturing technology generally accepted in the field of aviation manufacturing at home and abroad. The existing T-joints of aircraft fuselage panels are generally manufactured by riveting connection technology, but the riveted structure has limitations such as heavy weight, low production efficiency and high manufacturing cost, and is not conducive to the structural integrity of aircraft fuselage panels. ensure. Laser welding technology simplifies the structural design of this type of wall panel and uses materials for construction, which has become the development trend of panel structure manufacturing. Compared with traditional welding techn...
