Haltevorrichtung fuer Werkstuecke
The holding device has a carrier on which a holding element is attached to receive the workpiece. The shape of the holding element is designed to fit the shape of workpiece so that it can only be used for identical types of workpieces. The holding device is designed so that it can retain a large number of differently shaped workpieces. The holding element is therefore provided with at least one magnet whose poles are adjustable. In one pole position, the holding element is held to the carrier by magnet force and in the other pole position, it can be removed from the carrier. In the latter pole position, the magnetic circuit is diverted from the carrier so that the holding element can easily be removed from the carrier or placed in another position on it. By repositioning the holding elements, workpieces of different shapes can be perfectly held. The holding device can be used on machine tools, automatic assembly stations or similar.
