A robot joint

Abstract

The invention discloses a robot joint. A spring pressing plate and a steel ball capable of performing axial telescopic motion along a mechanical supporting structure are arranged in the supporting structure, a shallow pitch matched with the arc face of the steel ball is arranged on a steel ball pressing plate, and the steel ball pressing plate is connected with the mechanical supporting structure in a rotatable mode through a bearing connecting device. When torque is input on the mechanical supporting structure by the outside world, the steel ball drives the steel ball pressing plate to rotate, and when the torque is overlarge, the steel ball deviates from the shallow pitch of the steel ball pressing plate. An annular clamping groove with a groove is formed in a first connecting plate and connected with protruding bars on the side walls of the steel ball pressing plate in a clamping mode, and dual protecting effect occurs to the robot joint. The robot joint is simple and compact in structure and convenient and fast to disassemble and assemble, and achieves the overload protecting function on the joint under the condition that the normal electromechanical connection is not affected, and after the overloading disappears, the robot joint can conveniently and fast return to an original state to perform normal work.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a robot joint. Background technique [0002] With the rapid development of automobiles, chemicals, electronics, food processing, plastics, life sciences and other fields, especially in the field of robotic equipment, the transmission accuracy, safety and reliability, small size, and shock absorption of the drive joint transmission system Noise, light weight, maintenance-free and other performances put forward more stringent standards. [0003] Modular industrial robots change the limitations of traditional industrial robots, can adapt to complex and changeable working environments and given tasks, expand the application fields of industrial robots, and gradually become a hot spot in robot research. Modular robots are assembled from a series of modules. Through the free and flexible reconfiguration of the modules, they can be constructed into robot configurations with ...

Problems solved by technology

[0004] When the robot needs to perform operations such as picking and placing, handling, and drilling, it will generate a large load force; especially when the robot encounters sudden failures such as sudden loading and excessive acceleration, the load will increase greatly; if the electromechanical interface is simply transmitted The torque and impact force will be completely transmitted to each joint, which will easily cause damage to the robot parts; or require the size of the parts to increase and the drive power to increase, which will cause a waste of cost
