A connection system for connecting an interchangeable tool head to the spindle of a numerically controlled machine includes radially displaceable wedge members which when actuated radially to an outer clamping position provide for a clamping connection between the spindle and the tool head. When actuated to an inner release position the system allows for withdrawal of the tool head from the spindle. The wedge members are displaced by a central actuating rod connected to the wedge members via cam means such that the wedge members are positively driven by the cam means in both radial directions of movement.

Connection system for connecting an interchangeable tool head to a tool

The present invention deals with a bore head for deep-hole boring, in which a plurality of circumferentially spaced cutting members may be radially displaced in the bore hole by a common actuating device during operation. The actuating device includes an actuating rod for each cutting member, which actuating rod is in engagement with its associated cutting member by gear means including inclined teeth. The actuating rods are secured to a central actuating bar by a common connecting member. The bore head is interchangeably secured to a boring tube, and the actuating rod may be separated from the connecting member by a coupling which is automatically engaged and disengaged during changing of the bore head.

Bore head for deep-hole boring

A tool for a nc machine is provided with a radially displaceable surface slide serving as a tool holder. The tool head is interchangeable by a tool head changing device mounted on the nc machine. The tool head is automatically releasably mounted on the work spindle by means of a clamping cone and a tie rod concentrically disposed within the work spindle and engaging the conical surface of the clamping cone. There is provided a pair of control rods for radially displacing the surface slide and for limiting the radial movement of the surface slide, which control rods are adapted to be automatically separated by releasable clutches for interchanging the tool head (FIG. 1).
