Abstract

The invention discloses a seven degree-of-freedom cooperative mechanical arm. The seven degree-of-freedom cooperative mechanical arm comprises seven modular joints, two connecting arms and a base. Therotating end of the first modular joint is fixedly connected with the base, the fixed end of the first modular joint is fixedly connected with the rotating end of the second modular joint, the fixedend of the second modular joint is fixedly connected with one end of the first connecting arm, and the other end of the first connecting arm is fixedly connected with the fixed end of the third modular joint; the rotating end of the third modular joint is fixedly connected with the fixed end of the fourth modular joint, the rotating end of the fourth modular joint is fixedly connected with one endof the second connecting arm, and the other end of the second connecting arm is fixedly connected with the fixed end of the fifth modular joint; and the rotating end of the fifth modular joint is fixedly connected with the fixed end of the sixth modular joint, and the rotating end of the sixth modular joint is fixedly connected with the fixed end of the seventh modular joint. The seven degree-of-freedom cooperative mechanical arm can effectively improve the load / deadweight ratio, the structure is simple, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a novel configuration structure of a hollow series cooperative mechanical arm constructed of modular joints and connecting arms. 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 it is difficult to realize human-machine collaboration, which greatly affects assembly and operation. However, after the miniaturization design, the load capacity of the cooperative manipulator drops significantly. How to improve the load / weight ratio of the lightweight manipulator and improve the compactness of the structure has become an urgent problem to be so...
