A rotary connection device of a robot end effector

Abstract

The invention discloses a rotary connection device of a robot end effector, relates to the technical field of robots, and comprises a rotary connection arm and a fixed connection arm. cavity, the rear end of the positioning ring is provided with a driving cavity, the cavity of the rotating cavity and the front end surface of the positioning ring is sleeved with a rotating assembly, the cavity of the driving cavity is at the rear end surface of the positioning ring The fixed socket has a drive assembly. In the present invention, the mating surface of the rotating seat and the rotating connecting arm is a soft contact surface, thus reducing the stress concentration effect on the surface of the rotating seat, prolonging the service life of the rotating seat and the rotating connecting arm, and reducing the loss of the entire rotating assembly; In the invention, the main shaft of the driving motor is connected to the shaft end of the rotating shaft assembly through a coupling, which avoids the stress impact of direct plugging between the driving motor and the rotating shaft assembly, thus improving the service life of the entire device.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a rotary connection device of a robot end effector. Background technique [0002] Robots play a very important role in modern automated production. Through the precise control of workpieces by flexible robotic arms, various actions such as positioning, moving, testing and processing of workpieces can be realized. Compared with manual operations, robots have great advantages. Controllability, and its error rate is low, high efficiency, thus greatly improving the overall efficiency and quality of production, so it is widely used in the industry today. [0003] In the prior art, the end effector of the robot already has relatively flexible control to realize various actions such as clamping, grasping, and rotation, but there are still the following deficiencies in the actual operation: in high-speed rotation and high impact During processing, it is easy to produce stress concentrati...

Problems solved by technology

[0003] In the prior art, the end effector of the robot already has relatively flexible control, and can realize various actions such as clamping, grasping, and rotation, but there are still the following deficiencies in the actual operation: in high-speed rotation and high impact During processing, it is easy to produce stress concentration effect due to shock and vibration, which will easily cause stress erosion inside the rotating parts, which will easily cause damage to the rotating joints and need to be replaced frequently, thus increasing labor costs to a certain extent, and often The stoppage of the replacement will cause a certain loss to the production
