Abstract

The invention discloses a multi-freedom hollow cooperative mechanical arm, which includes seven modular joints, two connecting arms and a base. The rotating end of the first modular joint is fixedly connected to the base, the fixed end of the first modular joint is fixedly connected to the rotating end of the second modular joint, the fixed end of the second modular joint is fixedly connected to one end of the first connecting arm, The other end of the first connecting arm is fixedly connected with the rotating end of the third modular joint, the fixed end of the third modular joint is fixedly connected with the rotating end of the fourth modular joint, and the fixed end of the fourth modular joint is connected with the second One end of the connecting arm is fixedly connected, the other end of the second connecting arm is fixedly connected to the fixed end of the fifth modular joint, the rotating end of the fifth modular joint is fixedly connected to the fixed end of the sixth modular joint, and the sixth modular joint The rotating end is fixedly connected with the fixed end of the seventh modular joint. Adopting the invention can effectively improve the load/self-weight ratio, and has simple structure and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a multi-degree-of-freedom hollow series cooperative mechanical arm constructed of a joint module and a connecting arm. Background technique [0002] At present, collaborative robotic arms are gaining popularity in various industries. As people's requirements for the capabilities of manipulators and workplaces are getting higher and higher, the requirements for modularization and lightweight of collaborative manipulators are also gradually increasing. Existing collaborative robotic arms are often cumbersome, and the degree of human-machine collaboration is low, which greatly affects assembly and operation. However, after the miniaturization design, the load capacity of the manipulator is greatly reduced. How to improve the load / weight ratio of the lightweight cooperative manipulator and improve the compactness of the structure has become an urgent problem to be solved. The struct...
