Three-degree-of-freedom industrial mechanical arm capable of extending

Abstract

The invention discloses a three-degree-of-freedom industrial mechanical arm capable of extending, and belongs to the field of industrial robots. The three-degree-of-freedom industrial mechanical arm capable of extending comprises a mechanical small arm capable of freely extending, an elbow joint for connecting mechanical humerus with the mechanical small arm by adopting a hinge mode, a wrist jointfor connecting the right end of the mechanical small arm with a manipulator by adopting a hinge mode, a power mechanism A mounted on the mechanical humerus and capable of driving the mechanical smallarm to relatively rotate around the elbow joint, and a power mechanism B mounted on the mechanical small arm and capable of driving the manipulator to relatively rotate around the wrist joint; the mechanical small arm comprises a mechanical small arm body, a mechanical small arm extension rod and a small arm torsion joint; and the mechanical small arm body and the mechanical small arm extension rod are coaxially mounted, and can relatively move along common axis. The industrial mechanical arm is simple and compact in structure and more stable in movement, has three degrees of freedom, can freely extend, and has no vibration gap during extending.

Description

Technical field [0001] The invention mainly relates to the field of industrial robots, and specifically refers to a telescopic three-degree-of-freedom industrial mechanical arm. Background technique [0002] The research of robots has made great achievements and has been applied to all aspects of human life. Robots usually use robotic arms to work. At present, the research on robotic arms at home and abroad is mainly focused on the bending motion of the robotic arms, while the research on the robotic arms with both telescopic and bending motions is relatively rare. Therefore, in the special environment or harsh environment where industrial robots are used, the research on telescopic manipulators has very important use value. Summary of the invention [0003] The technical problem to be solved by the present invention is: in view of the technical problems existing in the prior art, the present invention provides a simple and compact structure, more stable movement, three degrees o...
