Holding device

The invention relates to a holding device for temporarily fixing a workpiece. The holding device comprises a workpiece holder (2; 53) which is designed for receiving a workpiece and / or for introducing a gripping force onto a workpiece, and which comprises a first magnet device (3), a second magnet device (4; 44) which is designed for magnetic interactions with the first magnet device (3) for the purpose of exerting bearer forces or load forces and gripping forces on the first magnet device (3); one of the magnet devices (3,4;44) has a permanent magnet assembly (5;55) having a magnetic field line path (8), and a magnet exciting coil; the other magnet device (3,4;44) has a superconducting device (6) with a magnetic field feature (7;64;77) matched with the magnetic field path (8); and the magnetic field feature is adapted for a relative positioning of the magnet devices (3, 4; 44) in at least one preferred position. 本发明涉及种用于暂时地地固定工件的保持装置，其带有工件架(2;53)，工件架(2;53)构造成用于容纳工件和/或用于将夹紧力引入到工件上且包括第磁性装置(3)以及带有第二磁性装置(4;44)
