METHOD AND DEVICE FOR NEGATIVELY COUNTERBALANCING AN IMPELLER, AND METHOD FOR PRODUCING A NEGATIVELY COUNTERBALANCED IMPELLER

摘要

The invention relates to a device for negatively counterbalancing an impeller (6), said device comprising a grip mechanism (1) provided with a grip drive (2) and a grip (4) for gripping the impeller (6). Said device also comprises a laser device (8) provided with a laser (9), and a positioning unit (10) for adjusting the position of the laser (9) and thus the laser beam (12) produced by the laser (9). The inventive device further comprises a control unit (14) that is embodied in such a way as to control the grip device (1) such that it grips the impeller (6) and positions the same (6) in relation to the laser device (8). Said control unit is also embodied in such a way as to control the positioning unit (10) and the laser (9) such that a pre-determinable contour (16) can be cut out of the impeller (6) by the laser (9). It is also used to control the grip device (1) in such a way as to position the impeller (6) and to release the same (6).
