Abstract
Description
Technical Field
[0001] This invention belongs to the field of laser processing technology, and specifically relates to a laser jet composite impact device. Background Technology
[0002] After years of research, laser processing methods have developed into a variety of applications, including laser cleaning, laser marking, and laser shock peening. Laser cleaning uses high temperature or impact to remove dirt, while laser shock peening uses high-power lasers to induce plasma shock waves to cause plastic deformation of the material surface.
[0003] In traditional laser devices, liquids typically serve as coolants or confinement layers, playing an auxiliary role. Laser-liquid hybrid processing is relatively rare, and laser equipment is generally complex and expensive. Therefore, there is an urgent need for a modular, detachable device that allows for disassembly and adjustment without affecting the normal operation of the laser, integrating laser processing and jet processing to improve processing efficiency, reduce costs, and optimize mechanical stability. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a laser jet composite impact device, comprising a substrate, a lens module, and a nozzle module. One side of the substrate has a trapezoidal groove, with the longer base on the inside and the shorter base on the outside. The internal laser emission channel, the lens module, and the external laser channel are aligned on the same straight line and coaxial. The lens module is located inside the substrate and includes a lens channel, a convex lens, a lens frame, and a lens frame sealing ring. The internal laser emission channel is a cylinder, with one end face inside the substrate, connecting to the light outlet of the laser generator. The other end face is in close contact with the inner end face of the lens channel, and the outer end face of the lens channel is in close contact with the outer end face of the external laser channel. Near the inner end face, the convex lens is located inside the lens frame and is coaxial. The lens frame is embedded inside the lens channel, and there is a lens frame sealing ring between the lens frame and the nozzle base. The nozzle module includes a nozzle base, an inner nozzle channel, an inner base channel, a nozzle channel sealing ring, and an outer laser channel. The nozzle base is generally trapezoidal and can be pushed into the base through the trapezoidal groove. The outer laser channel is located inside the nozzle base and is hollow. When in use, it is filled with liquid. One end of the inner nozzle channel is connected to the inner base channel, and the other end leads to the outer end of the nozzle module for emitting a liquid jet. The inner nozzle channel and the inner base channel are sealed with a nozzle channel sealing ring to prevent water leakage.
[0005] Furthermore, the trapezoidal groove can be another recessed shape with an inner space larger than the outer outlet, and a portion of the nozzle inner channel near the inner channel of the substrate faces the interior of the substrate, allowing the liquid to flow in this portion toward the interior of the substrate.
[0006] Furthermore, transparent materials, including but not limited to glass, can also be embedded inside the external laser channel.
[0007] Furthermore, a transparent material, including but not limited to glass, is embedded inside the laser emission channel.
[0008] The beneficial effects of this invention are as follows: This invention provides a composite processing device for laser processing and jet processing, which improves processing efficiency, facilitates assembly and disassembly, and has mechanical stability.
