Abstract
A boring and facing head for use in a machine tool comprising a body for insertion into a spindle on the machine tool, a tool, a slide mechanism for supporting the tool for movement transversely of the body, a series of shafts and gears for actuating the slide, and a coupling tongue located at the end of one of these shafts and slidably engageable with a rotary device supported by the machine tool whose rotary movement is precision-controlled by a numerical control unit.
Claims16
A boring and facing head for use in a machine tool, the combination comprising:
- a body adapted to be inserted into a spindle on the machine tool;
- a tool;
- first means, coupled to said body and said tool, for supporting said tool for movement transversely of said body;
- and
- second means, coupled to said first means and slidably engageable with a rotation device supported by the machine tool whose rotary movement is precision-controlled by a numerical control unit, for moving said tool transversely of said body in a precision-controlled manner,
- said second means being laterally spaced from said body.
A boring and facing head for use in a machine tool, the combination comprising:
- a body adapted to be inserted into a spindle on the machine tool;
- a tool;
- first means, coupled to said body and said tool, for supporting said tool for movement transversely of said body;
- and
- second means, coupled to said first means and slidably engageable with a rotation device supported by the machine tool whose rotary movement is precision-controlled by a numerical control unit, for moving said tool transversely of said body in a precision-controlled manner,
- said body including a lateral extension and a second extension extending perpendicularly from said lateral extension, and
- said second means including a rotatable shaft housed in said lateral extension, a tapered gear wheel coupled to said shaft, a second tapered gear wheel coupled to said tapered gear wheel, and a second rotatable shaft housed in said second extension and coupled to said second tapered gear wheel.
A boring and facing head for use in a machine tool, the combination comprising:
- a body adapted to be inserted into a spindle on the machine tool;
- a tool;
- first means, coupled to said body and said tool, for supporting said tool for movement transversely of said body;
- and
- second means, coupled to said first means and slidably engageable with a rotation device supported by the machine tool whose rotary movement is precision-controlled by a numerical control unit, for moving said tool transversely of said body in a precision-controlled manner,
- said second means including a rotatable shaft oriented at an acute angle to the longitudinal axis of said body.
A machine tool for the reception of a boring and facing head in an exposed surface thereof, the combination comprising:
- an open-ended spindle supported on the exposed surface for the slidable reception of the body of the boring and facing head;
- a rotary device, coupled to the exposed surface in a position spaced from said open-ended spindle, for transmitting rotary movement to the body of the boring and facing head and for slidably receiving a coupling tongue carried by the body;
- and
- means, coupled to said rotary device, for rotating said rotary device, said means being precision-controlled by a numerical control unit.
