Abstract

La présente invention porte sur un dispositif de centrage et de guidage pour une tige métallique qui peut centrer, guider et serrer une tige métallique traitée (13) et qui comprend un support (4), une douille à collet (7), un mandrin (9) et un manchon de guidage (5). Le mandrin (9) et la douille à collet (7) sont tous deux situés sur le support (4). Le manchon de guidage (5) est installé dans la douille à collet (7) qui est centrée par le mandrin (9). Des paliers (12) et des arbres (11) sont positionnés sur les mâchoires de serrage (14) présents dans le mandrin (9). Le mandrin (9) est entouré latéralement par une chemise de protection (10). Le dispositif présente une haute précision de centrage et permet d'éviter de rayer la surface de la tige métallique.
