Abstract
A boring apparatus comprises an elongate support body adapted to be rotatable by a machine tool spindle, a cutter mounting body releasably securable to the end of the support body remote from the machine tool spindle and is provided with a cutter guide which slidably receives a cutter therein which is constrained by the guide to be displaceable in an adjustment direction inclined to the rotational axis of the elongate support body. An adjustment member is disposed within the elongate support body and is movable along an axis substantially coaxial with the rotational axis of the elongate support body, and an interengaging coupling on the adjustment member and on the cutting tool is provided whereby movement of the adjustment member along its axis of motion induces movement of the cutting tool in its adjustment direction.
Claims21
A boring apparatus comprising:
- an elongate support body adapted to be rotatable by a machine tool spindle;
- first securing means for releasably securing said elongate support body to said machine tool spindle;
- an adjusting member disposed within said elongate support body and being movable along an axis which is substantially coaxial with the rotational axis of said elongate support body;
- coupling means on a first end of said adjusting member adapted to be releasably securable to an adjusting portion of said spindle which is extensible and retractable along said rotational axis in order to advance and retract respectively said adjustment member along said rotational axis;
- a first coupling component on a second end of said adjusting member opposite to said first end;
- a cutter support body releasably securable to the end of said elongate support body remote from said machine tool spindle;
- second securing means for releasably securing said cutter support body to said end of said elongate support body;
- cutter guide means in said cutter support body;
- a cutter slidably disposed in said cutter guide means and restricted by said guide means to be displaceable along an adjustment axis inclined to the rotational axis of said elongate support body as dictated by said guide means;
- a second coupling component on said cutter releasably engageable with said first coupling component on said ajusting member, whereby movement of said adjusting member along its said axis of motion induces movement of said cutter along said adjustment axis, and whereby removal of said cutter support body from said end of said elongate support body disengages said first and second coupling components of said adjusting member and said cutter respectively.

- a cutter support body releasably securable to the end of said elongate support body remote from said machine tool spindle;
- second securing means for releasably securing said cutter support body to said end of said elongate support body;
- cutter guide means in said cutter support body;
- two cutters slidably disposed in said cutter guide means and restricted by said guide means to be displaceable in opposite directions parallel to an adjustment axis inclined to the rotational axis of said elongate support body as dictated by said guide means;
- a second coupling component on each of said cutters releasably engageable with said first coupling component on said adjusting member, whereby movement of said adjusting member along its said axis of motion induces movement of said cutter along said adjustment axis, and whereby removal of said cutter support body from said end of said elongate support body disengages said first and second coupling components of said adjusting member and said cutters respectively.
