(FR) UNITÉ DE RACCORD RAPIDE POUR PINCES DE CHARGEUR À BARRES
Abstract:
(EN) Quick coupling unit for bar loader clamps (A), of the type comprising an end shaft (2) that can be accommodated rotatably within a corresponding seat (3) of a tubular body (4) that is integral with the bar pusher of said loader and an element (5) for stable coupling to the terminal stem (B) of the respective clamp (A), wherein said element (5) comprises a sleeve (6) provided with a recess (7) whose shape and dimensions are complementary to those of an insert (8) which can be accommodated in said recess (7), and wherein a locking ring (10) having a variable inside diameter surmounts said sleeve (6), the rotation of said ring (10) to a first configuration defining clamping of said insert (8) within said recess (7) and locking of said stem (B), and to a second configuration defining radial freedom of said insert and free exit of said stem (B).
(FR) La présente invention concerne une unité de raccord rapide pour des pinces de chargeur à barres (A), du type comprenant un arbre d'extrémité (2) qui peut être reçu de façon rotative à l'intérieur d'un siège correspondant (3) d'un corps tubulaire (4) solidaire du poussoir de barre dudit chargeur et un élément (5) d'accouplement stable à la tige terminale (B) de la pince respective (A), ledit élément (5) comprenant un manchon (6) pourvu d'un évidement (7) dont la forme et les dimensions sont complémentaires de celles d'un insert (8) qui peut être logé dans ledit évidement (7), et un anneau de verrouillage (10) ayant un diamètre intérieur variable surmontant ledit manchon (6), la rotation dudit anneau (10) dans une première configuration définissant le serrage dudit insert (8) dans ledit évidement (7) et le verrouillage de ladite tige (B), et à une seconde configuration définissant une liberté radiale dudit insert et une sortie libre de ladite tige (B).
