Description

Technical Field

[0001] The present invention relates to the technical field related to water-conducting laser cutting devices, and in particular to a water-conducting laser cutting processing device and a use method thereof. Background Art

[0002] Water-conducting laser processing technology is a method of processing with the help of a water conductor using a high-energy-density laser beam. It combines the high precision of laser cutting with the fast cutting speed of water jet cutting, and is suitable for cutting and processing a variety of metal and non-metal materials. The basic principle of water-conducting laser processing is to guide the laser beam from the laser to the processing area, and cool and clean the cutting area with a high-pressure water flow during the processing. Water-conducting laser processing technology is based on the principle of total internal reflection. A high-energy laser beam is generated by a laser, usually a fiber laser or a CO2 laser, which can generate a laser beam completely contained in a water jet. The laser beam is reflected at the air-water interface with a lower density medium. The laser beam propagates from the nozzle along the micron-level water beam to the surface of the workpiece. The laser is used to ablate the workpiece; water can be used to cool the cutting area and flush away the laser ablation debris in time. Compared with traditional laser direct ablation removal, water-conducting laser processing generates less heat accumulation and burrs, the surface of the processing area is smoother, and high-precision and straight-edge cutting effects can be obtained. Water-conducting laser processing technology is widely used in the field of high-precision and low-damage processing.

[0003] The role of waterjet laser is mainly reflected in the following aspects: waterjet laser technology combines the advantages of high-pressure water jet and laser cutting. High-pressure water jet can quickly remove melted materials during the cutting process, while laser provides high-precision cutting capabilities. This combination enables waterjet laser to complete cutting work with complex shapes and details in a shorter time; waterjet laser can cut a variety of materials, including metals (such as steel, aluminum alloy), composite materials, plastics, etc. This makes it widely applicable in industrial production, and it can play an important role in aerospace, automobile manufacturing or other engineering fields; compared with traditional laser cutting, waterjet laser can effectively reduce the heat affected zone of the cutting area because it uses high-pressure water jet at the same time. This is especially important for some materials that are sensitive to thermal deformation, and can maintain the geometric accuracy and material properties of the cutting part.

[0004] In addition, water-guided laser technology utilizes the energy of water and laser in the cutting process, which can reduce energy consumption and environmental pollution compared with traditional mechanical cutting and thermal cutting. This makes it more attractive in the context of today's increasing environmental awareness.

[0005] However, many water-guided laser cutting devices currently use a single clamping method, which makes them unable to adapt to the processing of various types of parts, reducing the processing range. The design of ordinary clamping devices may not be flexible enough. For the processing of different types of parts, it is usually necessary to replace the clamping structure or the operation of adjusting the device is complicated. In water-guided laser cutting, it is often necessary to replace the tool or adjust the clamping position to adapt to different workpieces and cutting requirements, which requires the clamping device to be able to be adjusted and replaced quickly and accurately. In addition, ordinary clamping devices may require a long downtime during maintenance and replacement, increasing production costs and reducing production efficiency. Summary of the invention
