Laser cladding head based on double-galvanometer system

The invention discloses a laser cladding head based on a double-galvanometer system. The laser cladding head comprises a light guide cylinder and a cladding end head arranged at the far end of the light guide cylinder, wherein a laser projection channel is arranged on the cladding end head; a first galvanometer, a second galvanometer, a focusing lens and a protective lens are sequentially arrangedin the laser projection channel from back to front along the projection direction of a laser beam; the rotation center line of the first galvanometer is vertical to the rotation center line of the second galvanometer; and the rotation center line of the first galvanometer is vertical to the projection direction of the laser beam in the light guide cylinder. The first galvanometer and the second galvanometer are driven to scan in the x-axis direction and the y-axis direction respectively to form rectangular light spots; the light spots enable the light beam irradiated on the surface of a material to be more uniform un
