Multi-freedom-degree air control joint, multi-freedom-degree air control device and mechanical arm

Abstract

The invention discloses a multi-freedom-degree air control joint. The multi-freedom-degree air control joint comprises a first mounting seat and a second mounting seat which are arranged oppositely. Multiple bendable telescopic bodies are arranged between the first mounting seat and the second mounting seat. The telescopic bodies are provided with cavities and openings capable of allowing gas to enter and be extracted out of the cavities. The opening ends of the telescopic bodies are connected with the first mounting seat, and the sealed ends of the telescopic bodies are connected with the second mounting seat. The structure of the multi-freedom-degree air control joint is simple, the rotating action, in multiple directions and angles, of a machine and precise control over the action directions and angles of the machine can be achieved, and stress buffer and safety protection can be effectively carried out. In addition, the invention discloses a multi-freedom-degree air control deviceand a mechanical arm.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a multi-degree-of-freedom air-controlled joint and a mechanical arm. Background technique [0002] As we all know, a robot is a multi-joint manipulator or a multi-degree-of-freedom machine device for many fields such as industry. It simulates the movements of human hands and arms, and in accordance with predetermined programs, trajectories and other requirements, to achieve grasping and handling of workpieces. Or operate the function of the tool. However, the joint, as the basic component of the mechanical arm of the robot, is usually arranged between two articulated arms, or on the end of the articulated arm for connecting functional devices, and its performance directly affects the working performance of the robot. [0003] At present, the joints of a robot are usually composed of a rotating motor, a reducer, and other structures, that is, through the cooperation of the rotatin...
