Mechanical arm with multiple freedom degree and achievement of more motion and method

Abstract

The invention discloses a mechanical arm with multiple freedom degree and achievement of more motion and a method. The problems in the prior art existing in a mechanical arm that a mechanical arm is small in moment of force, and more motion cannot be achieved are solved. The mechanical arm has the beneficial effects that motion of multiple freedom degrees can be achieved by the mechanical arm, themotion range of the mechanical arm is broadened, and the integral cost is low. According to the scheme, the mechanical arm with multiple freedom degrees and achievement of more motion comprises a base, a first arm, a second arm and a third arm. A gyratory mechanism is arranged on one side of the base. The first arm is a first telescopic mechanism. The telescopic mechanism is arranged between thebase and the gyratory mechanism. Rotation motion of the gyratory mechanism is driven by extension and contraction of the first arm. One side of the second arm is connected with the gyratory mechanism,and the other side of the second arm is connected with a middle support. A second telescopic mechanism is obliquely arranged on the second arm. The second arm is driven by the second telescopic mechanism to achieve pitching motion relative to the gyratory mechanism. One side of the third arm is connected with the middle support in a hinged manner. A pair of reversely-arranged third telescopic mechanisms are arranged in the third arm.

Description

technical field [0001] The invention relates to the field of mechanical arms, in particular to a mechanical arm and a method for realizing multiple movements with multiple degrees of freedom. Background technique [0002] In existing industrial production, a variety of mechanical arms are used. The mechanical arms help workers to produce and process or complete the production and processing independently, which can effectively reduce the labor intensity and labor pressure. At present, the forms of the mechanical arms are various, but the inventors found that the mechanical The arm cannot perform actions such as pitching, swinging, and rotating at the same time, and most of the existing robotic arms have the disadvantages of small torque and high cost, so many manufacturers are discouraged from using robotic arms. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a multi-degree-of-freedom multi-movement...
