Hydraulic artificial muscle

Abstract

The invention discloses hydraulic artificial muscle comprising a closed end connector, an elastic rubber tube, a high-strength fiber woven mesh, a water end connector, two end fastener rings, two middle fastener rings and two inverted-taper-tooth-surface fastener rings. When the hydraulic artificial muscle operates, the elastic rubber tube and the high-strength fiber woven mesh deform under the hydraulic action, the diameter of the hydraulic artificial muscle increases with the increased length, and a drive object connected to a threaded blond hole of the closed end connector is pulled. The elastic rubber tube closes water of certain pressure inside. The high-strength fiber woven mesh is in a tubular shape tightly woven with high-strength fibers and covers the outside of the elastic rubber tube, and accordingly the hydraulic artificial muscle can bear sufficient inner hydraulic pressure. Under the fastening action of the fastener rings and the structural action of the inverted-taper-tooth-surface and the shoulders, the hydraulic artificial muscle can bear large pull load, thus the high-strength hydraulic artificial is formed.

Description

technical field [0001] The invention relates to a fluid-driven artificial muscle used in the fields of robots, special operation manipulators, and automated production lines, in particular to a high-strength water pressure artificial muscle. Background technique [0002] In the drive and control of robot joints, fluid-driven artificial muscles are a new type of drive, which can be divided into pneumatic artificial muscles and hydraulic artificial muscles. Pneumatic artificial muscles have been applied in the fields of robots and automated production lines, and have the advantages of simple structure, smooth movement, and large output force / weight ratio. The hydraulic artificial muscle not only has the advantages of simple structure, but also helps to achieve miniaturization and light weight. Compared with pneumatic artificial muscles, it has higher output force, faster response speed and lower working noise. Artificial muscles have no relative friction moving parts. For und...

Problems solved by technology

[0004] The existing hydraulic artificial muscles still adopt the structure of pneumatic artificial muscles, which are generally in the form of rubber tubes, and the two ends are connected by fastened joints. Sparse, the strength is not high, the rubber cylinder will swell out from the pores of the braided mesh under high pressure, resulting in damage; the second is that the joints used for the two ends of the connection only clamp the rubber cylinder and the fiber braided mesh through fastening. Disengagement occurs under high tensile loads

The structure of existing artificial muscles cannot meet the strength requirements of hydraulic artificial muscles, and currently there is no high-strength hydraulic artificial muscle that can work under higher pressure and output force, so it is necessary to develop a new type of high-strength hydraulic artificial muscle to meet the requirements of water pressure artificial muscles. pressure and high output force requirements
