Abstract

L'invention concerne un dispositif de serrage destiné à une ou plusieurs pièces (6,7). Ce dispositif de serrage comprend plusieurs éléments de support (22) et plusieurs éléments de serrage (24).Ce dispositif de serrage (5) comprend plusieurs parties (8,9) mobiles les unes par rapport aux autres, qui serrent entre elles les pièces (6,7) en position fermée. Les parties (8,9) portent chacune une structure (20) de support et/ou de serrage qui présente plusieurs éléments de support (22) et plusieurs éléments de serrage (24) qui se font face. Les éléments de serrage (24) se présentent sous la forme d'éléments de compression pouvant être pressés contre les pièces (6,7). L'invention concerne également un poste d'usinage destiné aux pièces (6,7), comprenant un dispositif d'usinage (2), en particulier un dispositif d'assemblage, et un dispositif de serrage (5). En outre, l'invention concerne un procédé pour serrer la ou les pièces (6,7) dans un dispositif de serrage (5) qui comprend plusieurs éléments de support (22) et plusieurs éléments de serrage (24). Les pièces (6,7) sont insérées dans le dispositif de serrage (5) ouvert qui est constitué de plusieurs parties (8,9) mobiles les unes par rapport aux autres. Lors de la fermeture du dispositif de serrage (5), les parties (8,9) se déplacent les unes vers les autres et, une fois le dispositif en position fermée, les pièces (6,7) sont serrées entre les parties (8,9) et leurs éléments de support (22) et de serrage (24).
