Other AbstractThe invention discloses a laser head for strengthening laser shock for shielding parts of a blisk, and belongs to the field of laser shock strengthening treatment of blisks of aero-engines. The laser head comprises a numerical control rotary table, a swinging arm, a laser head tail end, a large focus lens, a small focus lens, a small reflector and a small reflector base; one end of the swinging arm is fixedly mounted on the numerical control rotary table, and the other end of the swinging arm is connected to the laser head tail end; the small reflector base is fixed at the end of the laser head tail end; the small reflector is embedded in a groove of the small reflector base; and the small focus lens is fixed at a light outgoing opening of the laser head tail end. When the laser beam having a light beam diameter of less than 27 mm, a wavelength of 1064 nm and a radiating angle of less than 3 mrad enters the laser head, circular light spots are formed on the surface of the vane, thereby achieving the strengthening of the laser shock for the shielding parts of the blisk. The laser head for strengthening laser shock disclosed by the invention facilitates the processing of the parts, which are hard to process and impossible for processing, on the blisk of an engine, and guarantees the uniformity and the stability of the laser shock strengthening quality.
