Title (EN) CLAMPING DEVICE WITH RADIALLY MOVABLE CLAMPING SEGMENTS
(FR) DISPOSITIF DE FIXATION MUNI DE SEGMENTS DE FIXATION A DEPLACEMENT RADIAL
Abstract: front page image
(EN)The present invention relates to a clamping device (1) for a tool holder (5), which comprises a tubular shaft (17) having at least two concave, abutment surfaces (18a) facing away from the free end of the tubular shaft (17), the clamping device (1) and the tool holder (5) being intended to be received from separate directions in a first through hole (20) of a coupling unit (3), and that the clamping device (1) comprises a drawbar (7) as well as means (10) for imparting the drawbar (7) an axial displacement in relation to the coupling unit (3). Characteristic of the clamping device (1) according to the present invention is that the clamping device (1) comprises at least two clamping segments (16), which are formed to move radially outwards or inwards upon a relative motion between the drawbar (7) and the clamping segments (16), and that the clamping segments (16) have convex abutment surfaces (33) that have a shape mating to the concave abutment surfaces (18a).
(FR)La présente invention concerne un dispositif de fixation (1) d'un porte-outil (5), qui comprend un manche tubulaire (17) présentant au moins deux surfaces attenantes concaves (18a) éloignées de l'extrémité libre du manche tubulaire (17). Le dispositif de fixation (1) et le porte-outil (5) sont destinés à se loger, à partir de directions séparées, dans un premier trou débouchant (20) d'une unité de couplage (3). Le dispositif de fixation (1) comprend une barre de traction (7), ainsi qu'un moyen (10) pour imprimer à la barre de traction (7) un déplacement axial relativement à l'unité de couplage (3). Le dispositif de fixation (1) de l'invention se caractérise en ce qu'il comprend au moins deux segments de fixation (16) conçus pour se déplacer radialement vers l'extérieur ou vers l'intérieur lorsqu'un mouvement relatif est accompli entre la barre de traction (7) et les segments de fixation (16). Il se caractérise en ce que les segments de fixation (16) présentent des surfaces attenantes convexes (33) dont la forme épouse celle des surfaces attenantes concaves (18a).
