APPARATUS FOR LASER PEENING HIDDEN SURFACES

A laser shock peening apparatus is provided for use with a workpiece having a cavity. The apparatus includes a tubular body configured for insertion longitudinally inward of the cavity. The tubular body has a peripheral wall bounding a laser delivery channel, and has an aperture reaching outward from the laser delivery channel through the peripheral wall. An optical device is located in the laserdelivery channel. The optical device is configured to direct a laser beam outward through the aperture. Additionally, the peripheral wall has internal surfaces defining a water delivery channel configured to convey a stream of overlay water to the aperture. 提供了一种与具有空腔的工件一起使用的激光冲击喷丸设备。所述设备包括管状主体，所述管状主体被配置为用于从所述空腔向内纵向插入。所述管状主体具有界定激光传输通道的外围壁，并且具有穿过所述外围壁从所述激光传输通道到达外部的孔。光学器件位于所述激光传输通道中。所述光学器件被配置为将激光束向外引导穿过所述孔。此外，所述外围壁具有限定水传送通道的内部表面，所述水传送通道被配置为将覆盖水流输送至所述孔。
