The present invention provides an improvement (20) in a Davenport~ automatic screw machine having a stationary spindle. The improvement broadly includes a quick-change mechanism (26) associated with the stationary spindle (22). The mechanism includes mating frusto-conical first and second surfaces (28, 31) on the spindle and tool holder, and a multi-lead threaded connection (32) between the tool holder and stationary spindle such that the tool holder may be quickly locked into mating engagement with the stationary spindle by relative rotation therebetween through a short angular distance. The invention may also include an adjustment mechanism (33) that allows the axis (X2-X2) of the tool to be aligned with the axis (X1-X1) of a spaced rotatable spindle. This adjustment mechanism includes a base member (34), an adjustment member (35), and a locking mechanism (37) for selectively holding the adjustment member in the desired position relative to the base member.

La présente invention concerne une amélioration (20) apportée à une visseuse automatique Davenport® à broche stationnaire. L'amélioration concerne d'une façon générale un mécanisme d'échange rapide (26) associé à la broche stationnaire (22). Le mécanisme comporte des premières et secondes surfaces tronconiques complémentaires 28, 31) sur la broche et le porte-outil, une liaison filetée à plusieurs filets (32) entre le porte-outil et la broche stationnaire de façon que le porte-outil puisse venir se bloquer rapidement en emboîtement avec la broche stationnaire par rotation relative entre eux par franchissement d'un écart angulaire court. L'invention peut également comporter un mécanisme de réglage (33) permettant d'aligner l'axe (X2-X2) de l'outil sur l'axe (X1-X1) d'une broche rotative écartée. Ce mécanisme de réglage comporte un élément de base (34), un élément de réglage (35) et un mécanisme de blocage (37) permettant de maintenir sélectivement l'élément de réglage dans la position voulue par rapport à l'élément de base.
