  • Patent number: 5458443
    Abstract: A drilling tool is adapted for incorporation into a riveting robot. For this purpose, the drilling tool with its spindle head is mounted on a slide that is motor driven for displacement in the Z-direction of an XYZ coordinate system. The slide in turn is mounted on a console provided with a flange to be secured or docked to the riveting robot. The console is rotatable about its longitudinal axis that extends perpendicularly to the drill spindle axis and intersects the latter approximately in the center of the spindle axis. The drill spindle is rotatably mounted in a spindle head and carries a drive wheel approximately in the center between the spindle ends. The drive wheel is meshing or cooperating with a power transmission train from a motor that is also secured to the slide and moves up and down with the slide and thus with the spindle head. Another motor drives the up and down movement of the spindle head. This type of arrangement permits positioning the drill bit in difficult locations.
