The invention discloses a large-batch special-shaped part laser shock processing device and method and relates to the field of laser shock processing. The large-batch special-shaped part laser shock processing device comprises an industrial control computer, a laser, an optical fiber and a light modulation device. The light modulation device comprises an outer cavity and an inner cavity with the light transmission bottom. The inner cavity is arranged in the outer cavity through a rotary shaft and is connected with the laser through the optical fiber. A motor capable of controlling the rotary shaft and the inner cavity to rotate is arranged outside the outer cavity. A rotary table is arranged at the lower portion of the inner cavity and provided with a focus lens. The bottom of the outer cavity is provided with a special-shaped lens matched with a part. The motor and the rotary table are connected with the industrial control computer. The defect that the thin area of the part sinks due to overhigh impact is overcome, the cost is lowered, and operating space is saved.
Description
technical field [0001] The invention relates to the field of laser shock strengthening, in particular to a laser shock strengthening device for large batches of special-shaped parts. Background technique [0002] There are many thin-walled parts such as engine blades in aero-engines. These parts are used in harsh environments and are prone to fatigue damage. Improving the reliability and service life of parts in the engine has an important impact on the performance and safety of aviation equipment. [0003] Laser shock strengthening technology can easily introduce residual compressive stress on the surface of the workpiece, thereby inhibiting fatigue damage such as microcracks on the surface of the workpiece, and greatly extending the service life of the workpiece. Compared with the existing surface strengthening methods such as cold extrusion and shot peening, it has outstanding advantages such as non-contact, flexibility, strong controllability and remarkable strengthening...
