Abstract
Disclosed is a device for use in machining an interior surface of a tubular object which comprises a pair of rails that can be longitudinally instad through the interior section of the tubular object. Braces join the rail for fixing the rails to the tubular object. A platform is movably mounted on the rails to allow longitudinal movement of the platform. A machine tool can be mounted on the platform.
Claims15
A device for use in machining an interior surface of a generally tubular object comprising:
- a rail means extending interiorly through said tubular shaped object;
- a brace means positionable in a plurality of angular positions on the interior surface of the tubular object for fixing the rail means to the tubularly shaped object;
- a platform means movably mounted on said rail means to be interiorly traversable through said tubularly shaped object, said platform having a machining means mount object thereon;
- and
- an angular position indicating means for indicating the angular position in which the brace means is located.
A device for use in machining an interior surface of a generally tubular object comprising:
- a rail means extending interiorly through said tubular shaped object;
- a brace means positionable in a plurality of annular positions on the interior surface of the tubular object for fixing the rail means to the tubularly shaped object;
- a platform means movably mounted on said rail means to be interiorly traversable through said tubularly shaped object, said platform having a machining means mount object thereon;
- and
- a lock means mounted to said brace means in said angular positions against the tubular object, said lock means having a lock shoe adjacent said exterior peripheral surface and operatively connected to said brace means, at least two lock arms, each lock arm having an exterior end, a medial portion, and an interior end, said lock arm exterior end being connected pivotally to said lock shoe, said lock arm medial portion being connected pivotally to said brace means, and said lock arm interior end being positionably connected to said brace means.
