The invention provides an automatic assembling and
welding device and method for bent ribs. The
welding device is formed by arranging an assembling device storage and grabbing
portal frame, a panel clamping mechanism, a guide rail base, an overturning jig frame, and a
welding portal frame. The welding device is used for automatically welding the bent ribs. According to the automatic assembling andwelding device and method for the bent ribs, automatic scanning, adjusting, assembling and welding functions of horizontal T-shaped section bars and bent T-shaped section bar ribs can be achieved, rib sections with the outer
diameter ranging from 6 m to 11 m and horizontal T-shaped section bars with the length
ranging from 1 m to 10 m can be machined, and the problem that welding reversible deformation is too large is solved. Tools can be saved, the construction period is shortened, the
assembly precision is improved, construction is easy, and the
assembly process can be effectively optimized. Meanwhile, the device has the advantages of simple and convenient
assembly mode, high assembly precision, high efficiency and wide
machining range. The method is suitable for being applied to automatic assembling and welding of the ship bent ribs.
