Description

Technical Field

[0001] The utility model relates to a tool position fine-tuning device for laser processing of tool surface micro-texture, belonging to the technical field of machining. Background Technique

[0002] The micro-texture on the tool surface refers to a microscopic structure created on the tool edge surface through precision machining technology. This structural design can achieve effects such as improving cutting performance, reducing wear, improving heat dissipation, and enhancing the stability of the edge at the cutting edge. Laser processing of micro-texture is a widely used manufacturing technology. Lasers can precisely control energy, achieve precision at the micron or even nanometer level, can manufacture complex geometric shapes, and laser processing does not contact the material surface, reducing the thermal impact on the material and protecting the original properties of the material, which is particularly suitable for processing tool materials. When processing a tool, an adjustment platform is required to fix and adjust the angle of the tool. The adjustment device needs to strictly control errors, has high requirements for equipment accuracy, and also needs to be easy to operate. When laser processing the micro-texture on the tool surface, there is a lack of precise control over the distance between the processing pattern and the cutting edge of the tool and the contact angle between the tool surface and the laser, which greatly affects the design effect of the micro-texture on the tool surface.

[0003] The Chinese utility model patent with the publication number CN206717549U discloses a knife grinder. An adjustment platform is installed on the workbench. The adjustment platform includes an X-axis platform that moves along the X-axis and a Y-axis platform that moves along the Y-axis. By setting the adjustment platform, grinding of the tool in the X-axis and Y-axis directions is achieved; a rotating table and a manual fine-tuning table are also provided on the adjustment platform, which can adjust the grinding position of the tool and the grinding wheel to achieve tool setting with the grinding wheel. A tool clamping device is also provided on the manual fine-tuning table. The tool clamping device includes a second Y-axis platform, a Z-axis platform, and a tool clamping head. The tool is clamped on the tool clamping head. Again, fine tool setting is achieved through the second Y-axis platform and the Z-axis platform, minimizing the tool setting error between the tool and the grinding wheel, thereby improving the grinding accuracy of the tool and reducing the grinding error; a knife grinding device is also provided on the vertical workbench. An elevating device is installed on the knife grinding device, which can adjust the grinding angle of the grinding wheel. Through the multi-axis control of the adjustment platform, the knife grinding device, and the tool clamping device, processing of the tool is achieved, reducing manual labor, improving the processing accuracy of the tool, reducing the processing error, and improving the processing efficiency.

[0004] When the above-mentioned knife grinder grinds a knife, it grinds through a grinding wheel, is provided with multiple axis platforms and a knife grinding device, and the operation process is complex, and the grinding wheel needs to be adjusted according to the grinding. Moreover, the accuracy requirements still cannot meet the requirements for forming micro-texture on the tool surface by laser processing. Therefore, there is an urgent need to design a device suitable for laser processing of different tool surfaces of a blade and capable of fine-tuning the position and angle of the tool.
