[CN 201721058163.0] Hydraulic mechanical gripper with internal oil circuit
[CN 201721058163.0] Title of Hydraulic Mechanical Gripper with Internal Oil Circuit: Application Number of Hydraulic Mechanical Gripper with Internal Oil Circuit: CN 201721058163.0 Applicant: Chongqing Lanlue Road New Technology Co., Ltd. Application Date: 2017-8-22 Patent Type: Utility Model The utility model discloses a hydraulic mechanical gripper with internal oil circuit, including a drive housing and a gripper. The drive housing is provided with a first oil circuit channel, a second oil circuit channel and an oil storage cavity, A piston is arranged in the oil storage cavity. The piston divides the oil storage cavity into an upper oil cavity and a lower oil cavity. The first oil passage and the second oil passage communicate with the upper oil cavity and the lower oil cavity respectively. The piston is connected with a piston rod. One end of the piston rod extends out of the oil storage cavity and is equipped with a gripper. When the piston rod expands and contracts, the gripper is driven to open or close, the hydraulic oil opened or closed by the driving gripper of the utility model flows in and out inside the driving shell, and there is no need to insert an external oil pipe around the driving shell. Compared with the traditional driving, it effectively reduces the rotation of the manipulator The weight of the joint improves its flexibility, and it will not interfere with the oil pipe like the traditional manipulator.
