Abstract

The invention discloses a modularized joint for a seven-freedom-degree cooperative mechanical arm. The modularized joint includes a shell, an end cover is installed at the top of the shell, a metal support is fixed to the inner upper portion of the shell, a servo motor fixing plate is fixed to the top surface of the metal support, and a servo motor is fixed to the top of the servo motor fixing plate; a power-off brake is fixed to the bottom wall of the servo motor fixing plate, a boss of a motor gear is inserted in a groove of a rotor of the power-off brake, the motor gear is fixed to the motor shaft in a sleeved mode, and a reducer is fixed to the bottom of the shell; a reducer gear is fixed above a wave generator of the reducer, a shaft segment of the wave generator is sleeved with a bottom sealing ring, a plurality of screw holes which are used for being connected with another modularized joint are formed in the soft bottom surface of the reducer gear, and the reducer gear and the motor gear are mutually matched with each other in an meshing mode; and the side wall of the shell is provided with a boss, a ladder hole is formed in the boss, and the axis of the ladder hole and theaxis of the reducer are in the same plane and are mutually perpendicular. The modularized joint is high in flexibility, convenient to control, and easy in installing and maintaining.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a modular joint for a seven-degree-of-freedom collaborative mechanical 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 it is difficult to realize human-machine collaboration, which greatly affects assembly and operation. However, after the miniaturization design, the load capacity of the collaborative manipulator has dropped significantly. How to improve the load / weight ratio of the lightweight collaborative manipulator and improve the compactness of the structure has become an urgent problem to be solved. [0003] The Chinese pat...
