Title
(EN) OPERATING HEAD WITH ELECTRO SPINDLES
(FR) TÊTE D'ACTIONNEMENT DOTÉE D'ÉLECTRO-BROCHES
Abstract
(EN)
An operating head with electro spindles comprises a central structure (10) rotating orthogonally to a work plane, able to support a plurality of electro spindles distributed on a circumference with the same angular distance, the axis of rotation of each electro spindle disposed radially with respect to the axis of rotation of the central structure (10). The central structure (10) comprises a substantially polygonal prismatic turret provided on each side face of a flanged seat (11) adapted to receive and support a cylindrical casing (12) of each electro spindle.
(FR)
L'invention concerne une tête d'actionnement dotée d'électro-broches, comprenant une structure centrale (10) tournant orthogonalement à un plan de travail, apte à soutenir une pluralité d'électro-broches réparties sur une circonférence avec la même distance angulaire, l'axe de rotation de chaque électro-broche étant disposé radialement par rapport à l'axe de rotation de la structure centrale (10). La structure centrale (10) comprend une tourelle prismatique sensiblement polygonale agencée sur chaque face latérale d'un siège à bride (11) conçu pour recevoir et soutenir un boîtier cylindrique (12) de chaque électro-broche.
