Abstract

The invention relates to the field of laser shock peening processing, and specifically relates to a light-water-coaxial laser shock peening device. The light-water-coaxial laser shock peening device comprises a shell body, a laser focusing lens, a laser window and a nozzle, wherein a hydraulic balance cavity is formed in the shell body, the laser window is formed in one side of the hydraulic balance cavity, and the nozzle is formed in the other side of the hydraulic balance cavity; a connector is formed in the shell body and communicates with the hydraulic balance cavity; the laser focusing lens is arranged in the shell body and arranged at the outer side of the laser window; laser enters from a rear-end opening of the shell body and sequentially penetrates through the laser focusing lens,the laser window and a liquid in the hydraulic balance cavity, and then is irradiated into the nozzle; a jet orifice is formed in a part at the outer side of the nozzle, of the shell body, the liquidforms a jet after passing through the nozzle, and the jet is sprayed out from the jet orifice; and the laser enters into the jet and spreads in a jet direction. According to the light-water-coaxial laser shock peening device, the problem that an existing laser shock peening device is difficultly applied to surface shock peening in a narrow and small space or a semi-enclosed space, is effectivelysolved.

Description

technical field [0001] The invention relates to the field of laser shock strengthening processing, in particular to a light-water coaxial laser shock strengthening device. Background technique [0002] Laser shock peening technology has been widely used in the surface performance strengthening treatment of structural parts of various metal materials. Laser shock peening technology generally uses water or mineral oil as a confinement layer to limit the plasma diffusion generated by the laser, thereby forming an effective shock wave to strengthen the workpiece material. Therefore, in the existing laser shock peening equipment, it is necessary to place a water jet nozzle near the workpiece so as to form a constrained layer on the surface of the workpiece. However, when laser shock peening is performed on surfaces in narrow or semi-enclosed spaces, water jet nozzles often do not have enough space to place them, which greatly limits the application range of laser shock peening t...
