Technical Field

The utility model relates to a carbon fiber resin combined material processing technology field especially relates to clamping device is used in profile machining in thin wall carbon fiber resin combined material conical member.

Background

The material composed of the carbon fiber reinforced material and the resin matrix is called carbon fiber resin composite material or carbon fiber reinforced plastic. Compared with glass fiber, the carbon fiber has high elastic modulus which is 4-6 times of that of the glass fiber, and the tensile strength is slightly higher than that of the glass fiber. The carbon fiber also has better high-temperature performance. Therefore, when the carbon fiber is combined with a resin matrix such as epoxy resin, phenolic resin, polytetrafluoroethylene and the like to form the composite material, the advantages of the glass fiber reinforced plastic are maintained, and the performance of the composite material is improved. For example, the strength and elastic modulus of the carbon fiber-epoxy resin composite material exceed those of aluminum alloy, even approach to high-strength steel, and make up for the disadvantage of low elastic modulus of glass fiber reinforced plastic. And the specific gravity of the composite material is smaller than that of glass fiber reinforced plastics, so that the composite material has the highest specific strength and specific modulus. Because the carbon fiber has high elastic modulus, the composite material part is allowed to be used in an ultimate stress state, and the defect that the glass fiber resin composite material is only allowed to be used under the condition of less than 60 percent of ultimate stress is overcome. The strength loss of the carbon fiber reinforced plastic in the high-temperature aging test is smaller than that of the glass fiber reinforced plastic. In addition, the material has the advantages of impact resistance, fatigue resistance, antifriction and wear resistance, self-lubrication, corrosion resistance, heat resistance and the like.

The carbon fiber reinforced plastics are mainly used for bearing parts (such as connecting rods), wear-resistant parts (bearings, sealing rings, pistons and lining plates) and corrosion-resistant parts (chemical pumps, high-pressure pumps, power sealing devices of hydraulic systems, pipelines and containers) in the mechanical industry. The gear material has large consumption, can meet the design requirements of metal gears, and has the advantages of light weight, self-lubrication and the like. When the material is used as automobile parts, the deadweight can be reduced 1/3, and the fuel saving effect is very obvious. In addition, it can be used to make the wingtips, tail wings, landing gear and many parts in aircraft. The nozzle is also selected from the aspects of a nose cone of a rocket, a nose cone of a missile, a nozzle of the rocket, a satellite bracket and the like. In conclusion, the emergence of carbon fiber resin composite materials provides excellent materials for modern industry and modern scientific and technical industry. Clamping tools are required to be used in the machining process of the carbon fiber resin composite material conical piece, the existing clamping device is mostly clamping pincers, clamping is not stable enough, and adjustment is inconvenient.
