    • The present invention concerns a clamping device (8) for magnetically holding a workpiece (7) in a precisely fixtured position, which comprises a base (10) having a first side (11) and a second side (12) at the larger opposed surfaces, a workpiece support plate (13) having a first side (14) and a second side (15) at the larger opposed surfaces, a first magnetic circuit (17) contained in said base (10) for creating a magnetic field, the first side (14) of said workpiece support plate (13) being attracted by the second side (12) of said base (10) by means of said magnetic field when said first magnetic circuit (17) is in an activated state, centering and locating means (20) for centering said workpiece support plate (13) in an angular position relative to said base (10). The clamping device (8) is characterized in that said at least one first magnetic circuit (17) comprises at least one pole piece (18) which is adapted to generate at least one magnetic flux for turning both said second side (12) and said first side (11) of said base (10) into a magnetically activated state, so that said first side (11) of said base (10) can be magnetically secured to a support (16) and that said second side (12) of said base (10) can be magnetically secured to said first side (14) of said workpiece support plate (13) thereby providing a one-piece configuration of said support (16) of said base (10) with said workpiece support plate (13).
    • 本发明涉及一种用于将工件(7)磁性保持在精确固定位置的夹紧装置(8),该夹紧装置包括在较大对置表面处具有第一侧面(11)和第二侧面(12)的基部(10) ,具有在较大相对表面处的第一侧(14)和第二侧(15)的工件支撑板(13),包含在所述基座(10)中用于产生磁场的第一磁路(17),所述第一 当所述第一磁路(17)处于激活状态时,所述工件支撑板(13)的侧面(14)被所述基座(10)的第二侧(12)借助于所述磁场吸引,定心和定位 用于使所述工件支撑板(13)相对于所述基座(10)处于角位置的定心装置(20)。 夹紧装置(8)的特征在于,所述至少一个第一磁路(17)包括至少一个极片(18),该极片适于产生用于转动所述第二侧(12)和所述 所述基座(10)的第一侧(11)成为磁性激活状态,使得所述基座(10)的所述第一侧(11)可以磁性地固定到支撑件(16)上,并且所述第二侧 所述基座(10)可以磁性地固定到所述工件支撑板(13)的所述第一侧面(14)上,从而将所述基座(10)的所述支撑件(16)的一体构型与所述工件支撑板(13) )。
