摘要： The invention relates to a magnetic holding device which holds the blanks (4), said blanks being made of ferromagnetic sheet metal and are to be welded to one another, on a fixing plate (1) by the force of a permanent magnet (6). The permanent magnet (6) can be adjusted from the holding position thereof on the blank (4) to a withdrawn neutral position by means of an adjusting cam in the form of a cylinder piston unit (18). In the neutral position, the magnetic force of the magnet on the blank (4) is too small in order to be able to hold the blank (4) on the fixing plate (1).

摘要： A magnetic chuck has a housing (1), a top plate (2) fixed to the housing, and an inner system (3) provided within the housing under the top plate. The top plate (2) comprises a plurality of spaced pole parts (7) of soft-magnetizable material and parts (9) of substantially non-magnetizable material positioned between them. The inner system (3) comprises, in a similar division as with the top plate, a plurality of pole parts (6) of soft-magnetizable material and magnetic elements (5) positioned between them. In the inner system (3), the center distance of adjacent pole parts (6) and magnetic elements (5), respectively, the so-called pole pitch, is smaller than ca. 8 mm. The inner system (3) is slidable parallel to the top plate (2) between the on- and off- positions, by means of a spindle and nut drive (11) and it can assume all intermediate positions. The magnetic chuck can particularly be used in combination with a pallet for reproducible positioning on the working table of a machining apparatus, wherein the pallet (4) is constructed as housing for the magnetic chuck. If the magnetic chuck is used in a condition submerged into a fluid, a fluid supply line is connectable to the chuck, and flushing holes (21) for the fluid open through the upper surface of the top plate. Said flushing holes (21) are distributed in a regular pattern (23) on the surface of the top plate (2) and are provided with screw-thread for receiving tap bolts of mechanical clamping elements or the like.
