Abstract

The invention provides an automatic balance adjusting system of mechanical arms, and relates to an automatic balance adjusting system. By the automatic balance adjusting system of the mechanical arms, the problems that the existing mechanical arm can apply idle work during movement due to the gravity of the existing mechanical arm, and the idle work can consume a large amount of mechanical power are solved. The automatic balance adjusting system comprises at least one mechanical arm, at least one hydraulic cylinder subassembly, a hydraulic driving system, an intelligent control system and a plurality of energy accumulators; a signal outputting end of the intelligent control system transmits a control signal to the hydraulic driving system; the hydraulic driving system controls movement of at least one hydraulic cylinder; each mechanical arm is matched with the corresponding hydraulic cylinder subassembly; each hydraulic cylinder subassembly moves to drive the corresponding mechanical arm to move; and the energy accumulators are arranged on the hydraulic cylinder subassemblies. Gravitational potential energy of the mechanical arms which work in a reciprocating manner is stored in the energy accumulators, and is released when the mechanical arms rise, power consumption on rising of the mechanical arms is reduced effectively, and the mechanical arms are prevented from applying idle work to a maximum extent. By the automatic balance adjusting system, ascending and descending of the mechanical arms can be adjusted.

Description

technical field [0001] The invention specifically relates to an automatic balance adjustment system of a mechanical arm. Background technique [0002] The robotic arm is currently the most widely used automated mechanical device in the field of robotics. It can be seen in industrial manufacturing, medical treatment, entertainment services, military, semiconductor manufacturing, and space exploration. Although their shapes are different, they all have a common feature, that is, they can accept instructions and precisely locate a certain point in two-dimensional or three-dimensional space for operation. [0003] For example, in construction machinery, the mechanical arm on the excavator or the cantilever crane needs to overcome the influence of gravity during the working process. Its self-weight during the lifting process often consumes a lot of mechanical power to do useless work, and these powers account for almost 10% of the total energy consumption. 50%, this situation no...
