Abstract

Selon l'invention, lorsqu'un ouvrier tente de serrer un boulon au niveau d'un point de serrage sélectionné, à l'aide d'une clé dynamométrique (10), le point de serrage est spécifié par une caméra (30) et la valeur prescrite pour le point de serrage spécifié est transmise d'un ordinateur (40) à la clé dynamométrique (10). L'ouvrier règle le couple de serrage de la clé dynamométrique (10) de façon à se situer dans la plage de la valeur prescrite. Après réglage, l'ouvrier serre le boulon au point de serrage spécifié. A ce stade de l'opération, le couple de serrage est transmis d'un émetteur (13) à l'ordinateur (40) par un moyen d'émission/réception (20). L'ordinateur (40) détermine si le couple de serrage correspond ou non à la valeur prescrite et affiche les résultats de la détermination. Si le résultat est satisfaisant, l'ouvrier passe au point de serrage suivant. Si le résultat n'est pas satisfaisant, l'ouvrier reprend l'opération de serrage.
