Multi-joint manipulator and mechanical arm

Abstract

The invention relates to the technical field of manipulators, in particular to a multi-joint manipulator and a mechanical arm. The multi-joint manipulator comprises a base, the middle of the upper end of the base is fixedly connected with a first rotating shaft, the upper end of the first rotating shaft is rotatably connected with a first crank arm, and the rear end of the first crank arm is rotatably connected with a second crank arm; and the middle of the right side of the second crank arm is rotationally connected with a first mechanical arm, the right side of the first mechanical arm is rotationally connected with a third crank arm, the front end of the third crank arm is rotationally connected with a fourth crank arm, the middle of the lower end of the fourth crank arm is rotationally connected with a second mechanical arm, the lower end of the second mechanical arm is fixedly connected with a tail end mechanical arm, so that the manipulator can clamp a clamped object more stably in the using process, the manipulator can clamp irregular objects more stably, the possibility that the objects are damaged in the moving process is reduced, economic benefits are enhanced, and the adaptability of the manipulator to different working conditions is improved.

Description

Technical field [0001] The present invention relates to the technical field of robotics, in particular a multi-joint robot and a robot arm. Background technique [0002] The robot refers to some of the actions that mimics the human hand and the arm, which can be controlled according to the set procedure, handling, etc. Automatic operation, robot can replace the people to carry out heavy labor to achieve the mechanization and automation of production, can be harmful to the human body In place of the person in the environment, the multi-joint robot is the joint structure, which can realize the grabbing of the object, the mechanical wall can realize the accurate movement of the robot in a certain space. [0003] However, there is an unstable condition when the mechanical work is taken, and there may be unstable cases, which may result in falling the object to be removed. [0004] To this end, a multi-joint robot and a robot arm are proposed. Inventive content [0005] It is an obje...
