[0002] Carbon fiber sheet is formed by hardening carbon fibers arranged in the same direction with resin, which can effectively solve the problems of difficult construction and large engineering volume of multi-layer carbon fiber cloth, with good reinforcement effect and convenient construction. It uses high-quality carbon fiber raw materials and good basic resin. Carbon fiber sheet has high tensile strength, corrosion resistance, seismic resistance, impact resistance and other good properties;

The utility model facilitates the adjustment of the center line position of the fiberboard through the coordinated use of the storage groove, the adjustment screw, the fixed sleeve, the block, the placing plate, the slide bar, the limit splint, the movable plate, the movable groove and the support plate, so that the subsequent cutting of the fiberboard is more convenient, and solves the problem that the fiberboard can only be cut at the center line when the cutting fixture is used because the center line position of the fiberboard cannot be changed. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] The existing fixtures are easily deformed or offset due to the high strength and light weight of the carbon fiber plate itself, but also have high brittleness and wear resistance. The offset will cause uneven force when the fixture clamps the workpiece, which may cause the workpiece to loosen or shift, seriously affecting the processing accuracy and quality. In addition, when sliding occurs, it will cause scratches, resulting in scratches on the surface of the carbon fiber plate.

[0005] Therefore, in order to solve the above problems, a cutting fixture device for carbon fiber pultruded plate inspection samples is proposed. Utility Model Content

[0017] Compared with the prior art, the cutting fixture device for carbon fiber pultruded plate inspection samples uses the resistance stripes of the lower clamping gasket and the resistance protrusions of the upper clamping gasket to abut against the upper and lower end surfaces of the pultruded plate body between the white steel plate and the clamping plate through their clamping force, thereby increasing the friction between the pultruded plate body and the pultruded plate body, so that the fixture device can more firmly fix the carbon fiber pultruded plate and prevent the pultruded plate body from sliding during the clamping process. At the same time, it provides a softer gasket contact surface to reduce damage to the carbon fiber plate, and can effectively avoid scratches and wear on the carbon fiber plate caused by the force generated by the strength of the mechanical clamp during cutting.
