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...
