Abstract
A cutting tool assembly including a cutter body having a cutting unit receiving pocket for releasably receiving a cutting unit with an operative cutting edge and an abutment surface remote therefrom. An elongated bore adapted for receiving an adjustment device is formed in the cutter body, the bore opening into the receiving pocket adjacent the abutment surface. The adjustment device includes an elongated tubular adjustment member having a longitudinally directed adjustment surface inclined with respect to its longitudinal axis, and an elongated adjustment screw initially slidingly extending through the adjustment member. The adjustment member is secured on the adjustment screw such that upon screwing the adjustment screw in a given direction, the adjustment member pushes the cutting unit outward.
Claims14
A cutting tool assembly comprising a cutter body having a cutting unit receiving pocket for releasably receiving a cutting unit with an operative cutting edge and an abutment surface remote therefrom;
- an elongated bore formed in the cutter body and opening into said receiving pocket adjacent said abutment surface via an elongated slot;
- an adjustment device located in said bore and comprising:
- an elongated tubular adjustment member longitudinally slidable in said bore and having a longitudinally directed adjustment surface inclined with respect to its longitudinal axis for abutting relationship with said abutment surface;
- and
- an elongated adjustment screw initially slidingly extending through said adjustment member for bi-directional screw displacement in respect of said cutter body;
- said screw being provided with a first abutment surface arranged to abut a corresponding second abutment surface on said adjustment member whereby screw displacement in a first direction results in an outward displacement of said cutting unit in an adjustment direction substantially transverse to said operative cutting edge, and
- said screw being further provided with a retaining member remote from said first and second abutment surfaces whereby screw displacement in a second direction opposite from said first direction results in a displacement of said adjustment member in said second direction.
An adjustment device comprising an elongated tubular adjustment member having a longitudinally directed adjustment surface inclined with respect to its longitudinal axis, an elongated adjustment screw slidingly extending through said adjustment member, said adjustment screw being provided with a first abutment surface arranged to abut a corresponding second abutment surface on said adjustment member and a retaining member remote from said first and second abutment surfaces for retaining said adjustment member on said adjustment screw.
