Abstract

The invention discloses an ultrastrong laser shock based thin plate connecting device and a connecting method thereof. The ultrastrong laser shock based thin plate connecting device comprises a work bench, a concave mold, a laser irradiation absorbing layer, a plasma wave constraining layer and a laser irradiation device, wherein a clamping support device for overlying two to-be-connected thin plates is arranged on the work bench, and a connection part is formed after the two to-be-connected thin plates are overlaid; the concave mold is mounted on the work bench and is supported below the connection part, so that the concave mold is used for supporting the connection part; the upper surface of the connection part is coated with the laser irradiation absorbing layer; the plasma wave constraining layer is arranged on the upper surface of the laser irradiation absorbing layer; the laser irradiation device is used for irradiating laser to the upper surface of the connection part. The thin plates can be precisely connected in an environment-friendly and controllable manner, the operability is high, the application range is wide, and the connecting device and the connecting method are applicable to connection of thin plates for marine, automobiles and rail transit engineering equipment.

Description

technical field [0001] The invention relates to a thin-plate connecting device and a connecting method based on super-strong laser shock, and relates to the technical field of installation of marine, automobile and rail transit engineering equipment. Background technique [0002] At present, with the development of the automobile industry, the connection of thin plates such as aluminum alloy plates and high-strength steel plates has attracted more and more attention. The traditional plate connection mainly includes: welding, riveting and screw connection. During the welding process, with the input of a large amount of welding heat, the plate will be deformed and internal residual stress will occur. Moreover, with the development of the automobile industry, more and more coated or coated plates are used, and the welding heat will damage the coating or coated layer to a certain extent. Threaded connections also have many inconveniences for thin plate connections, such as the...
