ABSTRACT:
The invention relates to a magnetic clamping device with a clamping body (1) comprising a cylinder plate (2) of non-magnetizable material provided with cylinders (5), a clamping plate (3) of non-magnetizable material situated at one side of the cylinder plate, a closing plate (4) situated at the other side of the cylinder plate, and pistons (9) made at least partly from magnetic material which are movable in the respective cylinders, which clamping body is further provided with channels (13, 14) to which a fluidic pressure source can be connected for the simultaneous movement of the pistons in the cylinders towards and away from the clamping plate. To improve the magnetic clamping action, all magnetic pistons (9) are fastened to a common piston plate (8). This ensures that all magnetic pistons, when energized, will exert their magnetic influence on the object to be clamped.
