Hydraulic lightweight parallel mechanical arm

Abstract

A hydraulic lightweight parallel mechanical arm belongs to the technical field of robot structures and comprises a moving platform connecting assembly, a big arm moving assembly, a mechanical big arm assembly and a hydraulic parallel mechanical forearm part, the big arm moving assembly is mounted on the moving platform connecting assembly, the mechanical big arm assembly is mounted on the big arm moving assembly, and the hydraulic parallel mechanical forearm part is mounted on the mechanical big arm assembly. Compared with other existing methods, the method has the beneficial effects that a mechanical arm forearm is assembled through a hydraulic assembly, the structure is lighter and more convenient, stepless speed regulation of the mechanical arm in the movement process can be achieved, and the movement precision is higher; the six-degree-of-freedom mechanical forearm is combined and assembled in a hydraulic parallel connection mode, six degrees of freedom of the mechanical forearm are achieved, and compared with other existing mechanical arms, the six-degree-of-freedom mechanical forearm is lighter and has a higher load self-weight ratio; and the assembly type combined mechanical arm is adopted, the requirements of various types of work can be met, and flexible conversion of various terminal execution components can be achieved through a replaceable execution terminal installation part.

Description

technical field [0001] The invention relates to a hydraulic lightweight parallel mechanical arm, which belongs to the technical field of robot structures. Background technique [0002] With the continuous advancement of robot technology, the application of robots can be seen everywhere in the fields of processing and manufacturing, life services, aerospace, medicine and medical engineering. But in the field of robot technology, the mechanical arm is the main structural part of industrial and construction robots, and it is the terminal component responsible for action execution and load force support. 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. The disadvantage of high terminal change cost. [0003] To sum up, t...

AI Technical Summary

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.
