The invention provides a saw blade
machining laser welding device which comprises a base, a fixing seat is fixed to the base, a supporting seat is installed on the side of the fixing seat, the supporting seat is fixedly installed on the base, a supporting plate is welded to the supporting seat, an open groove is formed in the supporting plate, an installation seat is movably installed in the open groove, and a
laser welding head is installed on the installation seat. A displacement mechanism and an adjusting mechanism are installed on the installation base, the displacement mechanism is fixedly installed on the supporting plate, a
laser welding head is fixedly installed at one end of the adjusting mechanism, an installation hole is formed in the supporting base, and an air draft
barrel is movably installed in the installation hole. According to the laser welding device for saw blade
machining, under pushing of the pushing mechanism, one end of the air draft
barrel descends, the rotating base at one end of the air draft
barrel makes contact with the saw blade to conduct up-down supporting and limiting, the rotating base rotates along with rotation of the saw blade in the later period, and therefore stability during rotation is guaranteed, and air is discharged through an opening to rapidly cool a welding point during welding.
