Abstract

La présente invention se rapporte à un dispositif de fixation de vis du type à percussion pour la fixation d'une vis, acheminée via un tuyau de percussion en forme de tube grâce à une pression externe, à une structure d'assemblage utilisant un foret de puissance. Le dispositif de fixation de vis du type à percussion comprend : un trou traversant de foret défini de manière à s'étendre de l'extrémité arrière à l'extrémité avant du corps de forme cylindrique du foret de puissance, afin de permettre au foret de puissance de passer à travers ; un corps constitué d'un élément muni d'un trou de raccord de support de percussion défini dans celui-ci, le trou de raccord de support de percussion étant formé à un certain angle par rapport au trou traversant du foret, depuis la périphérie externe du corps jusqu'au trou traversant du foret, de façon à ce qu'une extrémité du trou de raccord de support de percussion communique avec le trou traversant du foret ; un support de percussion, constitué d'un élément en forme de colonne cylindrique muni d'un trou de support de percussion défini en son centre, dont une des extrémités est raccordée au tuyau de percussion et dont l'autre extrémité est raccordée à un certain angle au corps ; et une tête de fixation, constituée d'un élément en forme de bloc auquel est accouplée une partie de préhension de vis disposée à l'extrémité avant du corps, pour fixer une vis qui est acheminée à travers le support de percussion en utilisant le foret de puissance et en le faisant avancer, puis pour détacher la vis du corps dans un état stationnaire, la partie de préhension de vis possédant une configuration étagée à ajustage flexible de manière à assurer le maintien d'une vis. L'autre extrémité du support de percussion est insérée dans le trou de raccord de support de percussion de manière à s'étendre jusqu'à une position au-delà de l'axe du trou traversant du foret, et un trou traversant de foret anti-interférence qui est concentrique par rapport au trou traversant du foret est défini dans l'autre extrémité du support de percussion afin d'éviter toute interférence avec le foret de puissance lorsqu'il pénètre dans le trou traversant du foret (illustration en figure 4).
