Problems solved by technology

The original technology is a carbon fiber cylinder without lining. In the process of composite carbon fiber winding, the control of the deformation of the inner hole of the cylinder and the dimensional accuracy and roughness of the inner hole after winding cannot meet the design requirements, and cannot withstand high pressure; when After the metal lining is added to the inner hole of the carbon fiber cylinder, when the cylinder is under high pressure, the expansion coefficients of the metal lining and the non-metallic carbon fiber cylinder are inconsistent

Abstract

The invention provides a composite carbon fiber oil cylinder capable of realizing oil supply by a cylinder bottom and a cylinder cover, belongs to the technical field of hydraulic cylinders, and aims to provide a carbon fiber oil cylinder which meets the design requirement on inner bore precision, geometric tolerance and degree of finish of a cylinder barrel and works stably under high pressure. According to the technical scheme, the cylinder barrel is formed by winding composite carbon fibers and nano materials, threads which are formed by winding the composite carbon fibers and the nano materials are respectively arranged at two ends of the cylinder cover, and threads are also machined at connecting ends of the cylinder bottom, the cylinder cover and the cylinder barrel; an oil cylinder reverse cavity inlet is formed in the cylinder cover, and an oil cylinder forward cavity inlet is formed in the cylinder bottom; and the invention is applied to the carbon fiber oil cylinder.

Description

technical field [0001] The utility model relates to a composite carbon fiber oil cylinder with oil through the cylinder bottom and the cylinder head, belonging to the technical field of hydraulic oil cylinders. Background technique [0002] Lightweight design is a development direction of hydraulic cylinders. The most fundamental advantage of composite carbon fiber cylinders is that they greatly reduce the weight of components and enhance their load performance. The original technology is a carbon fiber cylinder without lining. In the process of composite carbon fiber winding, the control of the deformation of the inner hole of the cylinder and the dimensional accuracy and roughness of the inner hole after winding cannot meet the design requirements, and cannot withstand high pressure; when After the metal lining is added to the inner hole of the carbon fiber cylinder, when the cylinder is under high pressure, the expansion coefficients of the metal lining and the non-metall...
