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 field of advanced laser manufacturing technology, and specifically relates to a progressive laser shock continuous riveting welding device and welding method for ultra-thin plates, that is, the riveting and welding of ultra-thin plates can be realized synchronously through pulsed laser impact, and the laser beam and The relative movement of the plates enables the gradual expansion of the riveting and welding area, and finally realizes the continuous linear riveting and welding composite connection. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In the field of modern machining and manufacturing, riveting and welding are...
