[0001] The utility model relates to the technical field of polishing, in particular to a surface polishing treatment device for carbon fibers. Background Art

[0002] With the development of industrial technology, carbon fiber has been widely used in aerospace, automobile manufacturing, sports equipment and other fields due to its high strength, light weight and corrosion resistance. However, during the production process of carbon fiber products, the surface often needs to be polished to remove burrs, improve surface finish or enhance coating adhesion.

[0003] Traditional carbon fiber product polishing methods mostly rely on manual operations, which are not only inefficient but also difficult to ensure the consistency of polishing quality. In addition, manual polishing and arc surface polishing require high technical skills of the operator, and long-term work can easily lead to fatigue. As for the polishing equipment, the equipment itself cannot adjust the inclination angle of the polishing disc according to the changes in the carbon fiber arc surface, and the polishing disc cannot retract for protection when under pressure, causing the polishing disc to break when unevenly pressurized. In addition, it has poor adaptability to carbon fiber products of different shapes and sizes.

[0004] Therefore, developing a device that can efficiently and accurately polish the surface of carbon fiber products while having good adaptability and economy has become an urgent problem to be solved. Utility Model Content

[0031] Working principle: When in operation, the rotating table 1 is driven by the motor to rotate, driving the truss 2 and the grinding assembly 3 to rotate to meet the grinding requirements of different positions;

[0032] When the first motor 4 drives the worm 21 to rotate, the worm wheel 22 rotates accordingly, driving the truss 2 and the truss 2 with the grinding assembly 3 installed to move along the set direction. The height or angle of the grinding assembly 3 is adjusted as needed to ensure that the grinding tool can fit the surface of the workpiece.
