A retractable three-degree-of-freedom industrial robot arm

Abstract

The invention discloses a retractable three-degree-of-freedom industrial mechanical arm, which belongs to the field of industrial robots. It includes a mechanical forearm that can be freely retracted, a hinged connection between the mechanical humerus and the elbow joint of the mechanical forearm, and a hinged connection between the right end of the mechanical forearm and the wrist joint of the manipulator. It is installed on the mechanical humerus to drive the mechanical forearm. The power mechanism A that rotates relatively around the elbow joint is installed on the mechanical forearm and can drive the power mechanism B for the relative rotation of the manipulator around the wrist joint; the mechanical forearm includes the mechanical forearm body, the mechanical forearm telescopic rod and the torsion Joint; the body of the mechanical forearm and the telescopic rod of the mechanical forearm are installed on the same axis, and can move relative to each other along their common axis. The invention is an industrial mechanical arm with simple and compact structure, more stable movement, three degrees of freedom, free expansion and contraction, and no vibration gap in expansion and contraction.

Description

technical field [0001] The invention mainly relates to the field of industrial robots, in particular to a scalable three-degree-of-freedom industrial mechanical arm. Background technique [0002] The research of robots has made great achievements and has been applied to every aspect of human life. Robots usually use mechanical arms to work. At present, the research on mechanical arms at home and abroad mainly focuses on the bending motion of the robotic arm, while there are relatively few researches on the mechanical arm that has both telescopic and bending motions. Therefore, in the special environment or harsh environment of industrial robot application, it is very important to study the retractable mechanical arm. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a simple and compact structure, more stable movement, three degrees o...
