[CN 201910029489.8] A Two-DOF Hydraulic Manipulator Joint with Ten Bytes Connection
[CN 201910029489.8] Title of a two-degree-of-freedom hydraulic manipulator joint with ten-byte connection: Application number of a two-degree-of-freedom hydraulic manipulator joint with ten-byte connection: CN 201910029489.8 Applicant: Zhejiang University Application Date: 2019-1-13 Patent Type: Invention Application The invention discloses a two-degree-of-freedom hydraulic manipulator joint with ten-byte connection, including a right oil cylinder assembly, a left oil cylinder assembly, a frame cross shaft, a support frame and a support arm; the cross shaft has a vertical rotation center line and two horizontal rotation center lines. One horizontal rotation center line is connected with the left piston rod of the left oil cylinder assembly through a rotation pair, the other horizontal rotation center line forms a rotation pair with the arm body, and the vertical rotation center line forms a rotation pair with the support frame. The right piston rod of the right oil cylinder assembly is installed on the support frame through a head hinge ten-byte assembly, the right oil cylinder of the right oil cylinder assembly is installed on the arm body through ten bytes; the present invention adopts a cross shaft structure, and the front end of the mechanical arm is hydraulically driven to simultaneously rotate around two axes with two degrees of freedom, which can be realized under heavy-duty working conditions. Flexible action has the advantages of large force-to-weight ratio, flexible action and stable action.
