The present invention concerns a clamping device for magnetically holding a workpiece in a precisely fixtured position, which comprises a base having a first side and a second side at the larger opposed surfaces, a workpiece support plate having a first side and a second side at the larger opposed surfaces, a first magnetic circuit contained in said base for creating a magnetic field, the first side of said workpiece support plate being attracted by the second side of said base by means of said magnetic field when said first magnetic circuit is in an activated state, centering and locating means for centering said workpiece support plate in an angular position relative to said base. The clamping device is characterized in that said at least one first magnetic circuit comprises at least one pole piece which is adapted to generate at least one magnetic flux for turning both said second side and said first side of said base into a magnetically activated state, so that said first side of said base can be magnetically secured to a support and that said second side of said base can be magnetically secured to said first side of said workpiece support plate thereby providing a one-piece configuration of said support of said base with said workpiece support plate

Abstract

The present invention concerns a clamping device for magnetically holding a workpiece in a precisely fixtured position, which comprises a base having a first side and a second side at the larger opposed surfaces, a workpiece support plate having a first side and a second side at the larger opposed surfaces, a first magnetic circuit contained in said base for creating a magnetic field, the first side of said workpiece support plate being attracted by the second side of said base by means of said magnetic field when said first magnetic circuit is in an activated state, centering and locating means for centering said workpiece support plate in an angular position relative to said base. The clamping device is characterized in that said at least one first magnetic circuit comprises at least one pole piece which is adapted to generate at least one magnetic flux for turning both said second side and said first side of said base into a magnetically activated state, so that said first side of said base can be magnetically secured to a support and that said second side of said base can be magnetically secured to said first side of said workpiece support plate thereby providing a one-piece configuration of said support of said base with said workpiece support plate
