Problems solved by technology

[0005] The purpose of the present invention is to provide a carbon fiber-resin composite material hydraulic cylinder design scheme with an integrated connection structure to solve the problem of the large mass of the all-metal cylinder and the corresponding hydraulic cylinder work in the prior art. The problem of unsatisfactory weight ratio; at the same time, a composite material hydraulic cylinder design with an independent structure is proposed to solve the problem of high maintenance cost of existing composite material hydraulic cylinders; at the same time, it provides a method that does not need to destroy the structural integrity of carbon fiber-resin composite materials The connection scheme can be realized, which solves the problem that the connection of the existing composite material hydraulic cylinder weakens the load-bearing structure

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, a carbon fiber-resin composite hydraulic cylinder barrel with an integrated connection structure provided by the present invention is similar in structure to a traditional hydraulic cylinder barrel, except that the outer layer 2 of the cylinder barrel and the tightly wound layer 4 are made of composite materials, and the sealing ring 3 In addition to selecting the corresponding standard parts according to the national standard, other parts are made of steel. The cylinder of the present invention includes a head coupling 1, a cylinder outer layer 2, a sealing ring 3, a tightly wound layer 4, a cylinder lining 5, a cylinder bottom 6, and hinged earrings 7; wherein, the head coupling 1, the sealing ring 3. The cylinder liner 5, the cylinder bottom 6, and the hinged earrings 7 together constitute the basic components of the cylinder; the ...

Abstract

The invention discloses a carbon fiber-resin composite material hydraulic cylinder barrel with an integrated connecting structure. The cylinder barrel comprises a head connecting piece, a hinge lug ring, a tight winding layer, a cylinder barrel outer layer, a cylinder barrel liner, a cylinder bottom and a sealing ring; the tight winding layer and the cylinder barrel outer layer are both cured by winding carbon fiber-resin composite materials at the outer peripheries of other parts; and the axial force transfer and the internal pressure bearing are mainly realized by the tight winding layer and the cylinder barrel outer layer. Compared with a traditional hydraulic cylinder barrel, the cylinder barrel has obvious weight reducing advantage; the carbon fiber-resin composite materials and metal parts are connected without by using such modes as threads, bolts, pins and clamping keys; the composite material structures are not locally damaged by machining; and the cylinder barrel can be repeatedly dismounted with other end covers and piston modules, and all structures are not damaged, so that the hydraulic cylinder is lower in total maintenance cost and difficulty compared with a bonding connection type composite material hydraulic cylinder.

Description

technical field [0001] The invention relates to a carbon fiber-resin composite material hydraulic cylinder barrel with an integrated connection structure. Background technique [0002] The development trend of hydraulic actuators is lightweight and high power-to-weight ratio. Traditional metal hydraulic cylinders generally use metal as the structural material; where the weight is particularly demanding, fiber-reinforced composite materials are generally used as the load-bearing structure. [0003] The specific gravity of carbon fiber-resin composite materials is much lower than that of steel; the tensile strength of carbon fiber is generally higher than 3500MPa, and the tensile strength of some carbon fiber materials can reach more than 4500MPa. These characteristics make carbon fiber reinforced composite materials have great advantages in manufacturing hydraulic cylinders. [0004] The hydraulic cylinders made of carbon fiber-resin composite materials that have appeared s...
