Abstract
Adsorbable electromagnetic field auxiliary device for large components, comprises an iron core being adsorbed on the component to be processed with an integral rectangular frame including a pair of lateral sides and a pair of longitudinal sides; lateral sides are installed with electromagnetic coils having opposite magnetic pole pointing to the component. A photoelectric sensor installed on the longitudinal side senses the real-time position of the laser head; the longitudinal opposite sides are each provided with a screw movement device and a brush device; the brush head of the brush device slides on the surface of the component forming a directional electric field; the motor controlled by the central controller adjusts the position of the brush device, so that the two brush heads and the laser head are always in a straight line to ensure the stability of the electric field in the laser processing area and uniformity.
