Buffering mechanism of robot

Abstract

The invention discloses a buffering mechanism of a robot. The buffering mechanism comprises a base, a robot body is arranged at the top of the base, plug pins are arranged at the four corners of the bottom of the base, and the ends, close to the base, of the plug pins sequentially penetrate through the base and the robot body and extend to the top of the robot body. The robot body and the base areboth movably connected with the plug pins, and compression springs are arranged at the four corners of the top of the base. According to the buffering mechanism, by arranging the compression springs,vibration can be weakened through deformation force, the remaining vibration force can be transmitted into shock pads to be further eliminated, the effect of improving the stability of the robot bodyin running can be achieved through double buffering of the compression springs and the shock pads, and the problems that an existing welding robot is not provided with a buffering mechanism, in the driving process on a complex road, dry collision is likely to happen between internal components of the welding robot, and consequently the service life of the welding robot is shortened are solved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a buffer mechanism of a robot. Background technique [0002] A welding robot is an industrial robot engaged in welding. A welding robot is a multi-purpose, reprogrammable automatic control operation machine used in the field of industrial automation. In order to adapt to different purposes, the mechanical interface of the last axis of the robot is usually a The connecting flange can be connected with different tools or end effectors. The welding robot is to install the welding tongs on the flange of the final axis of the industrial robot, so that it can be welded, cut or thermally sprayed. [0003] Some crawling welding robots are mostly driven by wheels, but the existing welding robots do not have a buffer mechanism. During the driving process on complex roads, the internal components of the welding robot are prone to dry collisions, resulting in a reduction in the service life o...
