A hydraulic lightweight parallel manipulator

Abstract

A hydraulic lightweight parallel mechanical arm belongs to the field of robot structure technology and is composed of a mobile platform connection component, a large arm mobile component, a mechanical large arm component and a hydraulic parallel mechanical small arm component. The large arm mobile component is installed on the mobile platform On the connection assembly, the mechanical boom assembly is installed on the boom moving assembly, and the hydraulic parallel mechanical small arm components are installed on the mechanical boom assembly. Compared with other existing methods, the advantages of the present invention are: using hydraulic components to assemble the small arm of the manipulator, which is lighter in structure, can realize stepless speed regulation during the movement of the manipulator, and has higher motion precision; adopts hydraulic parallel Combined assembly in a combined way to realize the six degrees of freedom of the robotic arm, compared with other existing robotic arms, it is lighter in weight and has a higher load-to-weight ratio; the assembled combined robotic arm can meet the requirements of various types of work, The flexible transformation of various terminal execution parts can be realized by using the replaceable execution terminal installation parts.

Description

technical field [0001] The invention relates to a hydraulic lightweight parallel mechanical arm, belonging to the technical field of robot structure. Background technique [0002] With the continuous progress of robot technology, the application of robots can be seen everywhere in the fields of processing and manufacturing, life services, aerospace, medicine and medicine. But in the field of robotics now, the manipulator, as the main structural part of industrial and construction robots, undertakes the final component of action execution and load force support. The main factor restricting the development of robots is that the manipulator has a single structure and adopts an integrated structure manufacturing method. By processing the entire rigid body, the manipulator is heavy in weight, high in cost, poor in flexibility, poor in positioning accuracy, and high in load-to-weight ratio. The disadvantage of the high cost of terminal change. [0003] In summary, there is a lac...

Problems solved by technology

The main factor restricting the development of robots is that the mechanical arm has a single structure. It adopts an integrated structure manufacturing method and processes the entire rigid body, resulting in heavy weight, high cost, poor flexibility, poor positioning accuracy, and high load-to-weight ratio. Disadvantages of high cost of terminal changes

[0003] To sum up, there is a lack of a lightweight robotic arm that is suitable for a variety of terminal actuators, has a high load-to-weight ratio, good flexibility, and high positioning accuracy.
