Abstract

The invention discloses a progressive laser shock ultrathin plate continuous rivet welding device and method. The rivet welding device comprises a pulse laser used for generating pulse laser; an optical splitter used for splitting the generated pulse laser into three laser beams, namely a first laser beam, a second laser beam and a third laser beam; a rivet welding die located below the optical splitter and comprising a first supporting plate, a second supporting plate and a base plate; a wedge block located above the base plate and located between the two supporting plates; and a pressing wheel arranged between the first supporting plate and the second supporting plate and located in the downstream of the wedge block. The upper surfaces of the first supporting plate and the second supporting plate are flush, a set gap is reserved between the first supporting plate and the second supporting plate, the base plate is located below the two supporting plates, and a set distance is reserved. The irradiation direction of a first laser beam and the irradiation direction of a second laser beam are located at the two sides of the pressing wheel respectively, and the irradiation direction ofa third laser beam is located between the pressing wheel and the wedge block.

Description

technical field [0001] The invention belongs to the technical field of advanced laser manufacturing, and in particular relates to a continuous riveting and welding device and a riveting welding method for a progressive laser shock ultra-thin plate, that is, the riveting and welding of the ultra-thin plate are synchronously realized by pulsed laser shock, and the The relative movement of the plate makes the progressive expansion of the riveted welding area, and finally realizes the continuous linear riveted and welded composite connection. Background technique [0002] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] In the field of modern machining and manufacturing, riveting and welding are the main ...
