Claims (6)

  1. Outil pour la fixation dans un porte-outil d'une perceuse à percussion, comprenant une tige de fixation sensiblement circulaire avec au moins deux rainures d'entraînement en rotation (14, 15, 34, 35) dont les flancs latéraux (16, 17) sollicités lors du perçage ne sont pas diamétralement opposés et débouchent, pour l'introduction axiale de tocs d'entraîne-ment en rotation du porte-outil, dans une surface terminale libre (18) de la tige de fixation (11), et deux gorges de verrouillage (12, 13, 22, 23, 32, 33) qui, pour recevoir au moins un corps de verrouillage (49) du porte-outil, sont fermées ou présentent une section transversale réduite au moins à leurs extrémités avoisinant la surface terminale (18) de la tige de fixation (11), pour limiter le mouvement axial de l'outil, caractérisé en ce que, pour assurer une répartition plus uniforme de l'aire de la section, les gorges de verrouillage (12, 13, 22, 23, 32, 33) ne sont pas diamétralement opposées.
  2. Outil selon la revendication 1, caractérisé en ce que, pour des rainures d'entraînement en rotation (14, 15, 34, 35) avec des sections transversales différentes, la rainure d'entraînement en rotation (15, 35) d'une section transversale plus petite se situe à l'intérieur d'un angle α inférieur à 180° formé par les deux médiatrices élevées sur les sécantes des gorges de verrouillage (12, 13, 22, 23, 32, 33).
  3. Outil selon la revendication 1 ou 2, caractérisé en ce que les gorges de verrouillage (22, 23, 32, 33) présentent des sections transversales variables.
  4. Outil selon l'une des revendications précédentes, caractérisé en ce que les sections (37, 38) des gorges de verrouillage (32, 33) qui avancent lors du perçage et avoisinent la tige de fixation (11) de section circulaire, s'étendent au moins sur une partie de l'aire de la section sensiblement à symétrie ponctuelle l'une par rapport à l'autre.
  5. Outil selon la revendication 3 ou 4, caractérisé en ce que la gorge de verrouillage (32) avec la section transversale plus grande présente une forme de section transversale (39) qui ne fait pas partie d'un cercle.
  6. Porte-outil pour outils de perçage à percussion, comprenant deux tocs d'entraînement en rotation (44, 45) diamétralement opposés et présentant des sections transversales différentes, lesquels sont prévus pour l'introduction axiale dans des rainures d'entraînement en rotation (34, 35) d'outils, et au moins un corps de verrouillage (49) guidé dans un évidement (41) du porte-outil et prévu pour l'introduction dans l'une des deux gorges de verrouillage (32) de l'outil, caractérisé en ce qu'une médiatrice élevée sur la sécante de la surface d'ouverture de l'évidement (41) pour le corps de verrouillage (49) dirigée vers l'outil forme avec, la médiatrice élevée sur la sécante du toc d'entraînement en rotation (45) plus petit, un angle β inférieur à 90°.
