Abstract

L'invention concerne un rail de guidage raccordé portatif, un procédé de raccordement associé et une pince de travail. Le rail de guidage raccordé peut être divisé en une partie de section de base (23), une section d'extension (22) et une partie de section d'extrémité (21) raccordées les unes aux autres. Les faces de raccordement sont reliées de manière à s'enclencher, ce qui permet d'empêcher l'apparition des défauts suivants : faible stabilité, faible force de liaison et précision réduite lors du raccordement sur un même plan horizontal. L'utilisation de deux paires de tiges de positionnement (3) et de trous de positionnement (5) sur la face de raccordement du rail de guidage (2) pour un positionnement précis permet d'obtenir un positionnement fiable lors de la liaison. L'interfonctionnement entre le rail de guidage (6) et une face de guidage (4) permet d'améliorer la précision de raccordement. Un arbre de clouage de tige auxiliaire (7) qui est relié de manière fixe garantit la stabilité structurale et l'intégrité du rail de guidage raccordé. La pince de travail dédiée permet d'obtenir une précision améliorée et une mise en œuvre pratique du procédé de liaison. Le rail de guidage raccordé, dans son intégralité, présente une structure simple et est facile à raccorder.
