Marine I-shaped sandwich plate laser welding tool and using method thereof

Abstract

The invention provides a marine I-shaped sandwich plate laser welding tool and a using method thereof. A clamp comprises an external panel fixing device and an internal web supporting assembly, wherein the external panel fixing device comprises an outer frame and a clamp group; the clamp group comprises a plurality of horizontal clamps; the horizontal clamps are divided into two rows and are oppositely arranged in the first direction and are in threaded connection with the outer frame; the internal web supporting assembly comprises a plurality of special-shaped magnets; and the cross sections of the special-shaped magnets are convex. According to the marine I-shaped sandwich plate laser welding tool and the using method thereof, the outer frame, the special-shaped magnets and the horizontal clamps are combined, the structure is simple, the design is reasonable, the operation is convenient, and the working efficiency and the welding quality of sandwich plate laser welding can be greatly improved.

Description

technical field [0001] The invention relates to the field of welding fixtures, in particular to a marine I-type sandwich plate laser welding fixture and a method for using the same. Background technique [0002] Compared with traditional marine steel structures, sandwich plate structures have higher specific strength and specific stiffness. While ensuring the overall structural performance of the ship, the use of I-type sandwich panels can greatly reduce the overall weight of the ship. In addition, I-type sandwich panels have the advantages of anti-corrosion, heat insulation, noise reduction, radiation reduction and impact resistance. They have been widely used not only in the field of ships, but also in aerospace, vehicle manufacturing, high-speed rail, light rail and construction packaging. . [0003] Laser welding is used to manufacture I-type sandwich panels, which can significantly improve production efficiency and reduce energy consumption. Compared with other weldi...

AI Technical Summary

Problems solved by technology

[0012] 1. The size of the magnetic welding fixture itself is too large, which is not suitable for laser welding of thin plates;

[0013] 2. The production of continuous corrugated sandwich units not only makes the process more complicated, but also has disadvantages such as low efficiency, high energy consumption, and unfavorable lightweighting;

[0014] 3. Adding solder at the contact interface between the panel and the web can effectively improve the welding quality, but it does not solve the problem of fixing the web;

[0015] 4. Manufacturing fixed molds or fixtures for specific dimensions greatly increases process costs;

[0016] 5. Filling the interlayer with material to make it a whole and welding not only increases the cost, but also increases the possibility of defects
