Abstract

The invention discloses a hydraulic system for a mechanical arm gripper, and the gripper, and belongs to the field of mechanical devices. The hydraulic system comprises a first control valve, an oil cylinder, an electromagnetic stop valve and a second control valve, wherein an oil port c of the first control valve communicates with a rodless cavity of the oil cylinder; a rod cavity of the oil cylinder communicates with an oil port a of the electromagnetic stop valve; an oil port b of the electromagnetic stop valve communicates with an oil port a of the second control valve; an oil port b of the second control valve communicates with an oil supply port of the hydraulic system; an oil port c of the second control valve communicates with an oil discharge outlet of the hydraulic system; the electromagnetic stop valve comprises a power off state and a power on state; when the electromagnetic stop valve is at the power off state, a direction from the oil port a of the electromagnetic stop valve to the oil port b of the electromagnetic stop valve does not communicate unidirectionally; and when the electromagnetic stop valve is at the power on state, the oil port a of the electromagnetic stop valve communicates with the oil port b of the electromagnetic stop valve. According to the hydraulic system for the mechanical arm gripper, and the gripper provided by the invention, the reliability of the gripper can be improved.

Description

technical field [0001] The invention belongs to the field of mechanical devices, and in particular relates to a hydraulic system and a claw for a mechanical arm. Background technique [0002] The gripper is an important part of the robotic arm, which mainly includes a gripper mechanism and a hydraulic system for controlling the gripper mechanism. 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] If there is an 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 grasped by the claw mechanism to fall.
