Problems solved by technology

These fixed solid molds are large in size, occupy a large space for storage, and have low utilization rate. Once the shape design of the aircraft is changed, the existing molds must be repaired, which increases the equipment cost and the part development cycle; in addition, the assembly of the fixed solid mold needs to be set up With a large number of fixed points, the complexity and occupied space of the required fixtures are multiplied, which is likely to cause the interference of the spatial structure

specific Embodiment 1

[0062] Specific embodiment 1: take the supporting mechanism as an example from the lowest position to be welded, that is, the initial support position to the position to be welded adjacent to the initial support position, the spatial coordinates of the support position are (X 2 ,Z 3 ), then the space coordinate of the translation position is (X 1 ,Z 1 ), the space coordinate of the rotated position is (X 2 ,Z 2 ), then the translational distance of the support mechanism X 1 =X 2 +Z 1 sina, support mechanism lifting height Z 3 -Z 2 = Z 3 -Z 1 cosa, since the slope tana of the tangent line on the back of the ribbed panel 4 is known, the value of angle a is obtained according to arctana. According to common knowledge in the field, the value of angle a is less than 360°, so the value of angle a obtained according to arctana is unique . When the value of angle a is obtained, the values ​​of sina and cosa are obtained immediately, so as to obtain the translation distance ...

Abstract

The invention relates to a supporting positioning device and method for laser welding of a ribbed wall board. The supporting positioning device for laser welding of the ribbed wall board comprise a bed body, a plurality of positioning tools for positioning the ribbed wall board are arranged on the bed body in the X direction, and the number of the positioning tools is adjusted adaptively accordingto the size and shape of the ribbed wall board. The positioning tools comprise mobile box bodies slidably arranged on the bed body and used for sliding in the X direction, telescopic positioning rodsmoving in the Y direction and the Z direction are arranged on the mobile box bodies, vacuum suction discs for fixing the ribbed wall board are arranged at the top ends of the telescopic positioning rods, and supporting mechanisms for supporting the ribbed wall board are arranged on the mobile box bodies. The welding of ribbed wall board bodies with in various shapes and sizes can be achieved, thewelding process stability is improved, welding deformation is effectively controlled, and assembly efficiency and degree of automation are improved.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a support positioning device and method for laser welding of ribbed wall panels. Background technique [0002] Ribbed panels are widely used load-bearing components in aircraft structures, and are generally processed from thin-walled skins with low stiffness and special curved surface configurations and long straight stringers. Laser welding has the advantages of high welding speed, small deformation after welding, good weld quality and easy automation. The T-joint double-beam laser welding process replaces the traditional riveting for the manufacture of ribbed panels, which can greatly reduce the structural weight factor and realize the lightweight of the airframe; the non-penetrating joint form on the back of the skin can meet the overall aerodynamic shape of the aircraft. Accurate, smooth streamlines and surface defects. [0003] Aircraft ribbed panels have the charact...
