Abstract
The device comprises a body longitudinally provided with a stem which is suitable for being inserted into the hole of a part being machined. On the body an element is slideably coupled which has an element for attachment to the mandrel of the machine tool, which element is adapted for imparting rotation to the body itself. On the stem is slideably mounted a shaft which is articulated at its end with a tool and is coupled to the attachment element so that an axial sliding of the same element towards the part being machined actuates a sliding motion in the opposite direction of the shaft adapted for actuating the radial projection of said tool from said stem.
Claims10
In combination, a machine tool mandrel and a device for performing spot-facings, in particular at non-accessible ends of through holes, said device comprising at least one attachment element, at least one tool, at least one shaft having an end, and at least one body having at least one longitudinal stem, said stem being adapted for insertion into a hole formed in a workpiece, said attachment element being attachable to said machine tool mandrel and slidably mounted on said body, said machine tool mandrel being adapted for rotation, said attachment element being adapted for imparting said rotation of said machine tool mandrel to said body, said shaft being slidably guided on said stem, said tool being articulated to said end of said shaft and rotatable between a position whereat said tool is aligned with said stem and a position whereat said tool projects radially from said stem, said shaft being coupled to said attachment element so that an axial sliding movement of said attachment element towards a workpiece actuates a sliding motion in an opposite direction of said shaft adapted for moving said tool to said position whereat said tool projects radially from said stem.
