Problems solved by technology

However, when the mechanical arm described in this patent is stretched, because the hinge pushed by its electric push rod is close to the joint, the moment of force applied by the electric push rod is too small, and the stretching of the mechanical arm will be very difficult. Moreover, when the mechanical arm is stretched Finally, the mechanical arm is completely supported by the electric push rod, which will bring an excessive burden to the electric push rod, thereby shortening the service life of the electric push rod

Abstract

The invention relates to the field of mechanical arm production manufacturing and particularly discloses a mechanical arm. The mechanical arm comprises a base, and a plurality of brackets sequentiallyconnected and hinged in series; the base is hinged to one bracket; a driving mechanism is arranged between the base and the bracket; a driving mechanism is arranged between every two adjacent brackets; the driving mechanisms can drive the brackets to be folded and stretch; and each driving mechanism comprises a telescopic rod, and a primary pushing rod and a secondary pushing rod which are hingedwith the telescopic rod. The mechanical arm further comprises a supporting mechanism; the supporting mechanism comprises a supporting rod and a flexible auxiliary piece; and the auxiliary piece abutsagainst the supporting piece and is used for steadily supporting the supporting rod. The mechanical arm can be folded, and can also stretch in a time-saving and labor-saving manner, and the mechanical arm can be steadily supported without driving force during stretching, so that energy consumption is low.

Description

technical field [0001] The invention relates to the field of manipulator manufacturing, in particular to a manipulator. Background technique [0002] The robotic arm is a widely used automated mechanical device, which can be seen in the fields of 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 locate to a certain point in three-dimensional (or two-dimensional) space for operation. The robotic arms in the prior art are mainly customized for factories or specific occasions. The actions that can be completed are programmed and fixed. There are few robotic arms that can be used in vehicles or mobile, and there is generally room for expansion. It is not wide, the volume is too large after folding, the supporting force is not enough, and the rigidity is not strong. [0003] Publication nu...
