Rotary connecting device of robot end executing mechanism

Abstract

The invention discloses a rotary connecting device of a robot end executing mechanism, and relates to the technical field of robots. The rotary connecting device comprises a rotary connecting arm anda fixed connecting arm, wherein a positioning ring is arranged in the middle of the rotary connecting arm, and a rotary cavity is arranged at the front end of the positioning ring; a driving cavity isarranged at the rear end of the positioning ring; a cavity, positioned at the front end face of the positioning ring, of the rotary cavity is sleeved with a rotary assembly; and a cavity, positionedat the rear end face of the positioning ring, of the driving cavity is fixedly sleeved with a driving assembly. According to the rotary connecting device, the matching surface of a rotary seat and therotary connecting arm is a soft contact surface, so that the stress concentration effect on the surface of the rotary seat is reduced, the service life of the rotary seat and the rotary connecting arm is prolonged, and the loss of the whole rotary assembly is reduced; and a main shaft of a driving motor is connected with the shaft end of a rotary shaft assembly through a coupler, so that the stress impact of direct plug-in connection of the driving motor and the rotary shaft assembly is avoided, and the service life of the whole rotary connecting device is prolonged.

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
