Title
(ES) Extensión polar móvil para un aparato de sujeción magnética y aparato de sujeción magnética que tiene tal extensión polar móvil
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 (Pl) 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).

(FR)
La présente invention porte sur une rallonge polaire mobile (4) pour un appareil de serrage magnétique (1) servant à maintenir une pièce à usiner ferromagnétique (P), ladite rallonge comprenant un élément polaire fixe (5) s'étendant dans une direction longitudinale prédéterminée (X-X) et au moins deux éléments polaires (6, 7) fixés au dit élément polaire fixe (5), lesdits au moins deux éléments polaires (6, 7) étant mobiles par rapport au dit élément polaire fixe (5). La rallonge polaire mobile est caractérisée par le fait qu'elle présente des moyens de support (8) couplés de manière fonctionnelle audit élément polaire fixe (5), lesdits moyens de support (8) étant mobiles dans ladite direction longitudinale prédéterminée (X-X) entre une première position fonctionnelle (P1) et une seconde position fonctionnelle (P2) et fonctionnent sur lesdits au moins deux éléments polaires mobiles (6, 7) pour les maintenir accouplés, en contact avec ledit élément polaire fixe (5).
