Description

Technical Field

[0001] This utility model relates to the field of magnetic clamping technology, specifically a magnetic clamping device for contour positioning of curved weld seams on ships. Background Technology

[0002] The magnetic clamp for contour positioning of curved welds on ships is a specialized auxiliary device for welding curved surfaces on ships. It uses a built-in magnetic system to firmly attach the clamp to the surface of a curved panel made of magnetically conductive material. At the same time, the contour structure design ensures that the clamp fits tightly with the curved surface of the workpiece, so as to achieve precise positioning and stable fixation of the weld, thereby effectively improving welding accuracy and work efficiency. It is especially suitable for welding operations of complex curved structures in shipbuilding. However, in actual use, it also has drawbacks such as insufficient adsorption stability, strong dependence on material, thermal deformation affecting positioning accuracy, limited operational flexibility, and high maintenance costs.

[0003] In shipbuilding, the welding quality of curved welds directly affects the strength and sealing of the hull structure. To improve welding accuracy and stability, existing technologies often employ magnetic clamps for curved weld seams to magnetically hold and fix curved workpieces. These clamps firmly fix the curved panels using magnetic attraction and, combined with a contoured structure, achieve a close fit with the workpiece surface, thus maintaining workpiece stability during welding.

[0004] However, in practical applications, the lack of effective alignment structures on both sides of the curved surface of a ship results in certain positional deviations or shape differences when the two curved surfaces are joined, affecting the precise joining of the weld. This difference not only increases the difficulty of welding adjustment, but also leads to uneven weld quality, aggravated welding deformation, and even affects the smooth progress of subsequent processes. Therefore, a magnetic clamp for conformal positioning of the weld seam on the curved surface of a ship is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a contour positioning magnetic clamp for ship curved surface welds, which has advantages such as improving the quality of ship curved surface welding. It solves the problem that when existing positioning magnetic clamps hold ship curved surfaces, the lack of an effective alignment structure on both sides of the ship curved surface leads to certain positional deviations or shape differences on both sides of the curved surface during docking, affecting the accurate docking of the weld. This difference not only increases the difficulty of welding adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:
