Automatic assembling and welding device and method for bent ribs

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of workpiece assembly, in particular to a device for automatic scanning, alignment, adjustment, assembly and welding of large-size high-strength steel curved rib assembly web panel end faces, in particular to an automatic assembly and welding device for curved ribs Devices and methods. [0002] technical background [0003] With the development of large-scale industrial equipment and tooling manufacturing industry, the assembly technology of large-scale structural parts urgently needs to be updated, and the assembly method of structural plates is shifting from the single manual assembly in the past to semi-automatic or automatic assembly; but for large-scale high-strength steel curved ribs Due to the special limitations of plate size, thickness, strength and other special restrictions on the assembly of web panels and large-size, high-strength, horizontal T-profile panel webs, the original methods of manual c...

Problems solved by technology

This method uses laser scanning for three-dimensional positioning, adjusts the height of the web end according to the space data of the panel scanning end point, and realizes the automatic centering of the panel web and the alignment assembly of the end face through the panel web clamping mechanism. The welding process does not require tack welding, and the panel web The clamping mechanism can automatically clamp and loosen according to the welding progress to ensure the shape retention and positioning of the panel web during the welding process, and solve the technical problems of positioning and assembly of curved ribs
