Title
(EN) "MOVABLE POLE EXTENSION FOR A MAGNETIC CLAMPING APPARATUS AND MAGNETIC CLAMPING APPARATUS HAVING SUCH MOVABLE POLE EXTENSION"
Abstract
(EN)
The present invention relates to a movable pole extension (4) for a magnetic clamping apparatus (1) for holding a ferromagnetic workpiece (P), comprising a fixed pole member (5) extending in a predetermined longitudinal direction (X-X) and at least two pole members (6, 7) attached to said fixed pole member (5), said at least two pole members (6, 7) being movable relative to said fixed pole member (5). The movable pole extension is characterized in that it has holder means (8) operably coupled to said fixed pole member (5), wherein said holder means (8) are movable in said predetermined longitudinal direction (X-X) between a first operating position (PI) and a second operating position (P2) and operate on said at least two movable pole members (6, 7) to hold them in coupled contact with said fixed pole member (5).
