Abstract

The invention discloses a mechanical arm hydraulic system, and belongs to the field of mechanical devices. The hydraulic system comprises an energy supply module, a shoulder joint module, an elbow joint module, a wrist joint pitching module, a wrist joint swinging module and a paw module; the paw module comprises a first control valve, a paw oil cylinder, an electromagnetic stop valve and a secondcontrol valve; the a oil port of the first control valve communicates with the oil supply port of the energy supply module; the b oil port of the first control valve communicates with an oil tank ofthe hydraulic system; the c oil port of the first control valve communicates with a rodless cavity of the paw oil cylinder; a rod cavity of the paw oil cylinder communicates with the a oil port of theelectromagnetic stop valve; the b oil port of the electromagnetic stop valve communicates with the a oil port of the second control valve; the b oil port of the second control valve communicates withthe oil supply port of the energy supply module; and the c oil port of the second control valve communicates with the oil tank. The reliability of a mechanical arm can be improved.

Description

technical field [0001] The invention belongs to the field of mechanical devices, in particular to a hydraulic system of a mechanical arm. Background technique [0002] The robotic gripper is an important part of the robotic arm, which is controlled by a hydraulic system. The hydraulic system usually includes an oil cylinder and a solenoid valve. The solenoid valve controls the expansion and contraction of the piston rod of the oil cylinder to realize the tightening and loosening of the claws. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] In case of unexpected power failure, the solenoid valve will not be able to control the oil cylinder, and the pressure of the oil cylinder will not be maintained, causing the heavy objects grabbed by the mechanical claws to fall. Contents of the invention [0005] The embodiment of the present invention provides a hydraulic system o...
