The invention discloses a driving cylinder-built-in type multi-degree-of-freedom mechanical arm. The mechanical arm comprises a shoulder component, a connecting piece, a large arm component, a small arm A component, a small arm B component and a tail end; the shoulder component and the connecting piece are used for completing deflection action of a shoulder through a piston cylinder; the connecting piece and the large arm component are used for completing bending and stretching actions of a large arm through a piston cylinder; the large arm component and the small arm A component are used forcompleting bending and stretching actions of a small arm A through a piston cylinder; the small arm A component and the small arm B component are used for completing bending and stretching actions ofa small arm B through a piston cylinder; and the small arm B component and the tail end are used for completing deflection action of the tail end through a piston cylinder. According to the mechanicalarm, power is supplied through hydraulic pressure, the mechanical arm is driven by the plurality of built-in piston cylinders, the driving cylinders are arranged in the axial direction of the mechanical arm, are arranged inside shells, so that the size is compact, and the integration degree is high. The plurality of piston cylinders drive the mechanical arm in parallel, so that five degrees of freedom are achieved, the mechanical arm has the multiple degrees of freedom and is suitable for heavy load working conditions, and has excellent engineering application prospect.
Description
technical field [0001] The invention relates to the field of hydraulic engineering, in particular to mechanical arm parts such as hydraulic robots and hydraulic mechanical arms. Background technique [0002] Hydraulic manipulators are widely used in various engineering fields, especially for heavy-duty working conditions. Many working conditions, especially some special working conditions, such as the heavy-duty rescue of the manipulator, require very high flexibility of the manipulator, which requires the manipulator to have multiple degrees of freedom. The traditional robotic arm has only three degrees of freedom, and the flexibility is far from the required requirements. Traditional robotic arms with more than three degrees of freedom are bulky and not highly integrated. Contents of the invention [0003] The object of the present invention is to design a multi-degree-of-freedom mechanical arm with a built-in drive cylinder in view of the deficiencies in the prior art...
