Abstract
A groove cutting assembly comprising a cutter housing, a cutter assembly with a cutting edge, and the cutter assembly being accommodated by the cutter housing, and a drive mechanism, coupled to the cutter assembly, for indexing the cutter assembly one of radially inward and radially outward relative to the cutter housing upon rotation of the cutter assembly past an indexing member. The drive mechanism comprises a barrel assembly, engaged with the cutter assembly, and a feed member which threadedly engages with the barrel assembly. Rotation of the feed member, in a first rotational direction, indexes the cutter assembly radially outwardly away from the cutter housing, while rotation of the feed member, in an opposite rotational direction, indexes the cutter assembly radially inwardly toward the cutter housing.
Claims20
A groove cutting assembly defining a longitudinal axis and comprising:
- a cutter housing defining a longitudinal through bore which extends along the longitudinal axis;
- a cutter assembly have a cutting edge, and the cutter assembly being accommodated by the cutter housing and being movable along the longitudinal through bore;
- and
- a drive mechanism, coupled to the cutter assembly, for automatically indexing the cutter assembly one of radially inward and radially outward, relative to the cutter housing and along the longitudinal through bore, upon rotation of the cutter assembly past an indexing member.
A groove machining combination comprising:
- a groove cutting assembly;
- a boring bar, the boring bar having at least one tool holder and a set screw is provided for securing the groove cutting assembly within the tool holder;
- a stationary indexing member;
- and
- the groove cutting assembly comprising:
- a cutter housing;
- a cutter assembly have a cutting edge, and the cutter assembly being accommodated by the cutter housing;
- and
- a drive mechanism, coupled to the cutter assembly, for indexing the cutter assembly one of radially inward and radially outward relative to the cutter housing upon rotation of the cutter assembly past an indexing member.
A method of forming a groove in a surface of a bore being repaired via a groove cutting assembly supported by a tool holder of a boring bar, and a stationary indexing member for indexing the groove cutting assembly, wherein the groove cutting assembly defines a longitudinal axis and comprises a cutter housing defining a longitudinal through bore which extends along the longitudinal axis, a cutter assembly have a cutting edge, and the cutter assembly being accommodated by the cutter housing and movable along the longitudinal through bore, and a drive mechanism, coupled to the cutter assembly, for indexing the cutter assembly one of radially inward and radially outward relative to the cutter housing and along the longitudinal through bore;
- and the method comprising the steps of:
- locating the groove cutting assembly in a bore being repaired:
- rotating the boring bar and the groove cutting assembly in a first rotational direction;
- and
- indexing, via the stationary indexing member, the groove cutting assembly one of radially inward and radially outward and along the longitudinal through bore each time the groove cutting assembly rotates past the stationary indexing member to machine the groove in the bore being repaired.
