Abstract

The invention relates to the technical field of laser additive welding, and provides a laser additive welding device which comprises a base, a support, a sleeve piece, an abutting plate, a first downward pressing piece, a second downward pressing piece, a first supporting plate and a second supporting plate. In the moving process of the abutting plate, under the condition that the long rod is fixed into the notch through the bolt, the abutting plate can synchronously push the sleeve piece to move along the outer surface of the support through the long rod, so that the welding head in the sleeve piece is located above the center position of the laser additive all the time, the bolt is rotated to be separated from the threaded groove, and the welding head is welded. At the moment, the limiting piece borne by the long rod disappears, and the long rod can freely rotate along the side face of the auxiliary plate under the condition that the long rod is hinged to the auxiliary plate, so that the long rod does not abut against the side face of the sleeve piece any more, and the sleeve piece can freely move on the outer surface of the support; the problem that the position of a welding head in a kit is inconvenient to finely adjust so as to more accurately weld the laser additive is solved.
