Problems solved by technology

The advantage of the magnetic suction docking mechanism is that the connection is flexible and fast, but only relying on electromagnetic attraction to connect parts has the disadvantages of low connection strength and poor stability
The traditional claw-type docking mechanism is complex in claw design and requires a drive and transmission mechanism, which is costly and heavy, and the docking lock fails due to the lack of claw claws during docking.
Therefore, the existing docking mechanism cannot meet the requirements in terms of connection stability, simplification and light weight

Abstract

The invention discloses a fast electromechanical docking device for a modular joint of a mechanical arm, belonging to the technical field of mechanical arm docking. The docking device of the present invention includes a first connection module and a second connection module respectively installed at both ends of the two mechanical arms, the first connection module and the second connection module cooperate to realize the connection and disconnection between the two mechanical arms . The fast docking mechanism of the manipulator module of the present invention is fixedly connected with the ends of the two manipulators or placed between other parts, and fixedly connected with other parts, the magnetic seat is attracted to the electromagnet, and at the same time, a memory wire is controlled to shrink , through the guide wheel, the cam is pulled to drive the four claws, and when reaching the highest point of the cam, the claws of the first connecting module are grasped and locked to realize the mechanical connection of the two mechanical arms. When the four claws in the second connection module lock the first connection module, the electrical connection spring contact contacts the electrical connection contact to realize electrical connection. The invention has small volume and light weight, and can quickly connect or separate the mechanical arms.

Description

technical field [0001] The invention belongs to the technical field of mechanical arm docking, and in particular relates to a fast electromechanical docking device for modular joints of a mechanical arm. Background technique [0002] The docking mechanism is a device that realizes the connection and separation between two robotic arm modules or other components. It has the characteristics of stable connection when docking, simple action when separating, and can quickly separate the two connected parts. Based on this docking mechanism, the assembly between different robot arms and other parts can be realized. However, the connection stability and docking simplicity of the current docking mechanism are insufficient. [0003] At present, various docking mechanism designs include magnetic suction docking mechanisms, claw-type docking mechanisms, and the like. The advantage of the magnetic suction docking mechanism is that the connection is flexible and fast, but the connection...
