Abstract

The invention relates to a chassis mechanism for a mobile welding robot. The chassis mechanism is driven in a differential mode and structurally comprises a machine body, a driving device, a permanent magnet adsorption device, and a falling-preventing device, an obstacle-avoiding device, and a guiding wheel. The driving device is arranged below the machine body and used for driving the robot chassis to move and swerve. The permanent magnet adsorption device is arranged at the bottom of the machine body, increases the adhesive force of the driving wheel and a working plane, increases stability of the machine body and prevents the driving wheel from skidding. The guiding wheel and the driving wheel commonly support a machine body platform. The obstacle-avoiding device is arranged in front of the machine body and used for detecting obstacles in front of the machine body. The falling-preventing device is arranged below the machine body to prevent the machine body from falling off from the working plane. The chassis structure for the mobile welding robot is flexible in moving and simple in driving and swerving mechanism, and has the obstacle-avoiding and falling-preventing functions.

Description

technical field [0001] The invention relates to a chassis mechanism of a mobile welding robot, belonging to the technical field of robots. Background technique [0002] In the prior art, the driving modes of the mobile robot chassis mechanism include wheel type, multi-legged type, crawler type and hybrid type and the like. Wheeled mobile robots are easy to control, consume the least amount of energy per movement unit distance, and usually move faster than tracked and multi-legged chassis mechanisms, so they are the most widely used. The chassis mechanism of wheeled mobile robot can be roughly divided into: direction-driven and differential drive; in the direction-driven mobile chassis mechanism, the control and drive of the direction are driven by different motors. Steering control and drive can be done on the same wheels (like a front wheel drive car), but speed and direction are controlled separately. The differential drive chassis mechanism uses the same wheels and driv...
