Abstract

The invention provides a double-acting hydraulic artificial muscle linear reciprocating actuator which comprises hydraulic artificial muscles, a pressure-isolating sealing linkage device and a guidingdeflector; each hydraulic artificial muscle comprises a closed end connector, a rubber pipe and a water passing end connector; the center of an inverted cone tooth surface portion of the closed end connector is provided with a cylindrical blind hole in an axial direction; the center of the water passing end connector is sequentially provided with a water passing hole A and a water passing hole Bin the axial direction from outside to inside; the pressure-isolating sealing linkage device comprises a cylinder linkage device, a pressure-isolating sealing main body and a sealing ring; the cylinder linkage device extends into a through hole of the pressure-isolating sealing main body; each of the two ends of the pressure-isolating sealing linkage device is connected with one hydraulic artificial muscle; the guide deflector is provided with a diversion trench, a diversion hole A, a diversion hole B, a diversion hole C and a diversion hole D; the diversion hole A, the diversion hole B, the diversion hole C and the diversion hole D communicate with each other; and the two ends of the cylinder linkage device extend into the diversion hole D of the guide deflector through clearance fit. Thedouble-acting hydraulic artificial muscle linear reciprocating actuator provided by the invention solves various problems caused by a complex structure of a hydraulic system of an existing hydraulicactuator.

Description

technical field [0001] The invention relates to the technical field of artificial muscles and reciprocating actuators, in particular to a double-acting hydraulic artificial muscle linear reciprocating actuator. Background technique [0002] At present, fluid-driven artificial muscles are a new type of drive, which can be divided into pneumatic artificial muscles and hydraulic artificial muscles. Pneumatic and hydraulic 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. The output force of the fluid-driven artificial muscle increases with the increase of the working pressure. Incre...
