Problems solved by technology

[0002] The prior art such as DE 299 04 532 U1 describes the clamping of workpieces machined by workpiece holders with magnets, but there are many disadvantages: the workpiece is too small with its supporting surface and the available holding force is too small, wherein the image diameter is approximately Thin-walled rings such as bearing rings in the range of 250 to 5000 mm basically cause such problems due to their shape; moreover, the workpiece may move due to the forces generated by the machining process; A lot of time must be spent to correctly position the workpiece before clamping

Embodiment Construction

[0014] figure 1 It is a schematic front view of a chuck 1 that can realize the present invention to be operated manually or by force, and this figure can be used to illustrate the present invention, because the present invention can continue to use the chuck 1 of the prior art to operate the jaws 2 without modification basic structure. figure 1 Indicates a chuck body 3, in which a plurality of 6 jaws 2 are radially arranged, and a pole piece 7 with at least one electromagnet 4 is arranged below the jaws 2 of the chuck body 3, as shown The embodiment is to set 6 electromagnets 4 again, and they are placed between the adjustment ranges of the claws 2 . According to a non-illustrated embodiment, each magnet segment 5 can also have regions of different polarity divided by the center, wherein adjacent regions of adjacent magnet segments retain their different polarity unchanged. The magnet fields 5 are delimited by these electromagnets, wherein adjacent magnet fields 5 have diffe...

Abstract

The invention relates to a method for chucking workpieces (6) sensitive to deformation, particularly thin-walled rings, wherein the workpiece (6) to be chucked is placed between the clamping jaws (2) of a chuck (1) comprising a pole block (7) having at least one magnet (4) in the chuck body (3) thereof beneath the clamping jaws, and wherein the workpiece is centered by closing the clamping jaws (2) and fixed in this centered position by the magnet (4). The invention further relates to a chuck (1) comprising a magnet (4) disposed in a pole block (7) beneath the clamping jaws (2).

Description

technical field [0001] The invention relates to a method for clamping deformable workpieces, especially thin-walled rings, in which the workpiece to be clamped is placed between the jaws of a chuck which has a Pole piece with at least one magnet, the workpiece is centered by locking the jaws and held in this centered position by the magnet. The invention also relates to a chuck for carrying out the method. Background technique [0002] The prior art such as DE 299 04 532 U1 describes the clamping of workpieces machined by workpiece holders with magnets, but there are many disadvantages: the workpiece is too small with its supporting surface and the available holding force is too small, wherein the image diameter is approximately Thin-walled rings such as bearing rings in the range of 250 to 5000 mm basically cause such problems due to their shape; moreover, the workpiece may move due to the forces generated by the machining process; A lot of time must be spent to correctly...
