Title (EN) JAW-TYPE CENTERING DEVICE FOR BAR LOADERS IN AUTOMATIC LATHES
(FR) DISPOSITIF DE CENTRAGE DE TYPE À MÂCHOIRES POUR CHARGEURS DE BARRES DANS DES TOURS AUTOMATIQUES
Abstract:
(EN) A centering device (10) is intended for use in an automatic bar loader for a lathe. The centering device (10) comprises a channel (11) with a rectilinear axis (12), intended for the passage of a bar from the loader to the lathe, and also comprises mobile jaws (17, 18) on the sides of the channel (11) for defining an adjustable through- aperture in the channel. The jaws (17, 18) are mounted on respective sliding guides (18, 20) which guide the jaws for their sliding opening movement in a direction radial to the channel (11) in response to a thrust on the jaws in the channel axial direction towards the outlet end (16). A loader with such a centering device is also described.
(FR) Dispositif de centrage (10) destiné à être utilisé dans un chargeur de barres automatique pour un tour. Le dispositif de centrage (10) comprend un canal (11) ayant un axe rectiligne (12), destiné au passage d'une barre du chargeur au tour, et comprend également des mâchoires mobiles (17, 18) sur les côtés du canal (11) pour délimiter une ouverture traversante réglable dans le canal. Les mâchoires (17, 18) sont montées sur des guides coulissants respectifs (18, 20) qui guident les mâchoires en vue de leur déplacement d'ouverture coulissant dans une direction radiale au canal (11) en réponse à une poussée exercée sur les mâchoires dans la direction axiale de canal vers l'extrémité de sortie (16). L'invention porte également sur un chargeur doté d'un tel dispositif de centrage.
