[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and sashes. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of the load-bearing rods (rods that bear and transmit deadweight and loads) and doors and windows composited with wood and plastic, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. Aluminum alloy doors and windows need to be welded using welding equipment;

The utility model can adjust the position of the laser welding head by using a screw motor, and the height of the laser welding head by using a welding cylinder.

[0029] The welding air cooling mechanism 300 includes a movable seat 301, and a cylinder 302 is installed on the upper surface of the movable seat 301. The telescopic end of the cylinder 302 passes through the movable seat 301 and is fixedly connected to a mounting plate 304. Both sides of the mounting plate 304 are fixedly connected to a clamping seat 305. Two groups of clamping seats 305 are clamped with air outlet pipes 307. One end of the two groups of air outlet pipes 307 are connected to an air guide pipe 308. The air guide pipe 308 is convenient for connecting with an external device blower, and then the air is blown to the connection node where the window frame is connected through the air outlet pipe 307, which is convenient for cleaning impurities before welding and cooling the weld, thereby improving the quality of window frame welding.
