Embodiment Construction

[0052] An autonomous mobile double-sided double-arc welding robot system, including a robot body, a control system and a welding system, is characterized in that:

[0053] The robot body includes a crawling mechanism and an operating mechanism: the crawling mechanism includes a front wheel module using a drive-steering integrated magnetic wheel, a rear wheel module using a permanent magnetic gap adsorption device, a frame connecting the front and rear wheels, and a vehicle mounted on the frame. The motor drives the controller, the crawling mechanism is a three-wheel structure, and the three wheels are driving wheels, and the steering on the magnetically conductive wall surface is realized by redundant control steering; the operating mechanism is installed on the crawling mechanism;

[0054] The control system includes a sensing system, a robot body control box and a robot main control system; the sensing system includes a laser tracking sensor, an environment monitoring sensor ...

Abstract

The invention belongs to the technical field of robot welding, particularly an autonomous mobile double-sided double-arc welding robot system. The autonomous mobile double-sided double-arc welding robot system comprises robot bodies, a control system and a welding system; the robot bodies, the control system and the welding system are connected by cables; two robot bodies, two sets of robot body control boxes, two sets of sensing systems and two welding guns are provided; each two sets of corresponding equipment are symmetrically arranged; and the two robot bodies are respectively adsorbed at both sides of a workpiece to be welded. The autonomous mobile double-sided double-arc welding robot system has the advantages that a creeping device adopts a contact magnetic wheel adsorption and non-contact clearance adsorption composite mode and is of a three-wheel structure; all wheels are driving wheels; a redundancy control steering mode is adopted; the steering on a magnetic conducting wall surface is implemented by the differential velocity of two rear wheels and the controlled steering of the front wheel; the steering accuracy of a wall climbing robot is improved by accurately controlling the steering angle of the front wheel; the autonomous mobile double-sided double-arc welding robot system has good movement flexibility, can steer around the center of a vehicle body and has the minimum steering radius of 0; and a robot can be reliably adsorbed on the magnetic conducting wall surface and the free and flexible movement of the robot can be implemented.

Description

technical field [0001] The invention belongs to the technical field of robot welding, in particular to an autonomous mobile double-sided double-arc welding robot system. Background technique [0002] The double-sided double-arc welding process is for large thick-walled workpieces with symmetrical grooves and double-sided simultaneous welding. Compared with the traditional asymmetrical grooves of large and thick plates, there is no need to heat up the welding surface first, and preheat the welding surface before gouging. , carbon arc gouging, grinding, magnetic particle inspection and other intermediate construction processes, which greatly reduce the labor intensity of workers, significantly improve welding production efficiency, shorten the construction period, and reduce production costs. [0003] For example, the patent application number is CN200410082758.0, the application date is 2004-11-8, and the invention patent named "double-sided double-arc welding method" has a t...
