Laser line generator tool for a pipe machining apparatus
A pipe machining apparatus according to an aspect includes a frame capable of being mounted onto a pipe, a tool carrier coupled to and movable relative to the frame, a tool support coupled to and movable with the tool carrier relative to the frame, and a laser line generator tool mounted on and movable with the tool support. The laser line generator tool is used to image a laser light onto the pipe to align with a mark(s) on the pipe which denotes a proper cut line around the pipe. The apparatus can be repositioned relative to the pipe in order to enable an operator to properly position the apparatus on the pipe prior to a cutting operation.
1. A pipe machining apparatus comprising:
a frame capable of being mounted around a pipe;
a tool carrier coupled to and movable relative to the frame such that the tool carrier is rotatable around an outer diameter of the pipe;
a tool support coupled to and movable with the tool carrier relative to the frame, the tool support having a passageway therethrough;
a laser line generator tool capable of being mounted in the passageway of the tool support and capable of being removed from the passageway of the tool support, the laser line generator tool being movable with the tool support when mounted thereon, the laser line generator tool imaging a laser light onto the pipe as the tool carrier is rotated around the pipe; and
a cutting or machining tool capable of being mounted in the passageway of the tool support when the laser line generator tool is not mounted in the passageway such that the laser line generator tool and the cutting or machining tool are interchangeably mounted within the passageway, the cutting or machining tool capable of being removed from the passageway of the tool support, the cutting or machining tool being movable with the tool support when mounted thereon, the cutting or machining tool cutting or machining the pipe as the tool carrier is rotated around the pipe when mounted on the tool support.
2. The pipe machining apparatus of claim 1 , wherein the laser line generator tool comprises a housing that defines a centerline and a laser line generator that defines a centerline, the centerline of the laser line generator being offset from the centerline of the housing.
3. The pipe machining apparatus of claim 2 , wherein the laser line generator tool is offset 1/4 ″ from the centerline of the housing.
4. The pipe machining apparatus of claim 1 , wherein the laser line generator tool is fixed to the tool support by a set screw.
5. The pipe machining apparatus of claim 1 , wherein the tool support comprises an inner housing and outer housing which can be detached from each other, the inner and outer housings forming the passageway.
6. The pipe machining apparatus of claim 1 , further comprising adjustable members attached to the frame and configured to be engaged with the pipe, the adjustable members being used to adjust the position of the frame relative to an exterior surface of the pipe.
7. The pipe machining apparatus of claim 1 in combination with a pipe, the pipe having marks on an exterior surface thereof, the laser line generator tool being configured to image laser light onto the marks as the tool carrier is rotated around the pipe.
