Abstract
A material removal having a plurality of cartridges mounted on an active portion where a plurality of seating members mounted in each of the plurality of cartridges pivots about an axis between a retracted position and an extended position is disclosed. Alternative embodiments have a single pivotable seating member. The pivotable extending seating members operate to extend and retract in a scissors-like motion and enable compact and efficient machining operation, particularly for crank shaft bearing supports.
Claims27
A material removal tool, comprising:
- a housing body including a mounting portion and an active portion;
- a plurality of cartridges mounted on the active portion of the material removal tool;
- and
- a plurality of seating members mounted in each of the plurality of cartridges to pivot about an axis between a retracted position and an extended position, the plurality of seating members including a pocket with a seating surface for a cutting insert,
- wherein, in the plurality of cartridges, the axis is located transverse to a longitudinal axis of the tool and axially between the pocket of a first of the plurality of seating members and the pocket of a second of the plurality of seating members.

A material removal tool, comprising:
- a housing body including a mounting portion and an active portion;
- a plurality of cartridges mounted on the active portion of the material removal tool;
- a plurality of seating members mounted in each of the plurality of cartridges to pivot about an axis between a retracted position and an extended position, the plurality of seating members including a pocket with a seating surface for a cutting insert;
- a piston head in an actuating chamber internal to the housing body;
- and
- a translating bar internal to the housing body, the translating bar including a plurality of actuation surfaces correspondingly positioned relative to the plurality of cartridges;
- wherein the translating bar includes a first end operably connected to the piston head to axially translate between a first position and a second position when the piston head translates,
- wherein in the first position, the plurality of seating members are in the retracted position, and
- wherein in the second position, the plurality of seating members are in the extended position.

A material removal tool, comprising:
- a housing body including a mounting portion and an active portion;
- a plurality of cartridges mounted on the active portion of the material removal tool;
- a plurality of seating members mounted in each of the plurality of cartridges to pivot about an axis between a retracted position and an extended position, the plurality of seating members including a pocket with a seating surface for a cutting insert;
- and
- a translating bar internal to the housing body, the translating bar including a plurality of actuation surfaces correspondingly positioned relative to the plurality of cartridges,
- wherein cartridges at substantially the same axial position are radially opposing each other,
- wherein pivoting of the seating members is actuated by translation of the translating bar operating through the actuating surface contacting a push pin,
- wherein the actuating surface has a variable radius along a set axial distance,
- wherein as the actuating surface moves relative to the push pin, the radial position of the end of the push pin along the axis changes in correlation to the variable radius of the actuating surface, and
- wherein the change in radial position of the end of the push pin directly or indirectly changes the position of or creates a force operating on the seating member.
