[CN 201820671177.8] Wrist Joint of All-Sea Deep Hydraulic Manipulator
[CN 201820671177.8] Wrist Joint Title of All-Sea-Deep Hydraulic Manipulator: Wrist Joint Application Number of All-Sea-Deep Hydraulic Manipulator: CN 201820671177.8 Applicant: Hangzhou Yukong Electromechanical Engineering Co., Ltd. Application Date: 2018-5-7 Patent Type: Utility Model This utility model relates to a hydraulic manipulator and aims to provide a wrist joint of all-sea-deep hydraulic manipulator. The wrist motor in this product includes a motor housing and a motor end face distribution plate of a multi-acting inner curve radial piston hydraulic motor. The axial section of the motor output shaft is T-shaped, and its disc-shaped outer end is located between the motor rear end cover and the claw base. The shaft part passes through the motor rear end cover, the motor housing, the motor end face distribution plate, the motor front end cover and the lock nut pressing plate; the inner end side of the motor output shaft is provided with two distribution channels, and the outer end side shaft center is provided with a cavity as the cylinder body of the gripper cylinder. The utility model transforms the very mature ordinary multi-acting inner curve radial plunger hydraulic semi-motor through structural transformation to make it structurally complete, with angle detection and flow distribution functions for the gripper cylinder, greatly reducing the cost and significantly improving the reliability; Short size, light weight, high integration, low cost, high reliability, large output torque, low minimum stable speed, and wide application range.
