Abstract

A tool head, in particular for turning and boring operations, comprises a base, an eccentric sleeve disposed therein, and a tool holder whose rearward portion engages in the eccentric bore of the eccentric sleeve, has a mounting for a tool, and may be displaced relative to the base, and secured in the position set. The eccentric sleeve forms a setting member rotatably mounted in the base and has a peripheral portion located between a front contact surface of the base and a support surface of the tool holder. The tool holder is guided so as to be non-rotatable relative to the base but displaceable transversely. An abutment for one part of a clamping device is provided on the base so that it is non-rotatably connected thereto or formed thereby. The clamping device clamps the tool holder at its support surface to the base at the contact surface thereof, also clamping the peripheral portion of the eccentric sleeve.

Dependent claims

A tool head comprising:

a base member adapted to be attached at one end to a machine tool;
a contact surface on the other end of said base member;
a cylindrical bore in said base member open at said other end;
a cylindrical sleeve rotatably supported in said bore;
a flange on said sleeve slidably engaging said contact surface on said base member;
a cylindrical eccentric bore in said sleeve having its central axis eccentric to the axis of said cylindrical bore in said base member;
a tool holder having one end in said eccentric bore and having a tool mounting means at the other end;
means to prevent relative rotation and allow relative transverse displacement between said tool holder and base member;
a support surface on said tool holder slidably engaging said flange on said eccentric sleeve;
said flange being disposed between said contact surface on said base member and said support surface on said tool holder;
axial clamping means operatively mounted within said tool holder to clamp said tool holder and eccentric sleeve to said base member to prevent relative axial displacement thereof;
means for actuating said axial clamping means;
and
radial clamping means operatively disposed within said cylindrical bore in said base member to clamp said tool holder and eccentric sleeve to said base member to prevent relative rotation thereof in response to actuation of said axial clamping means.
