Abstract

In one aspect, a pipe machining system is provided and includes a positioning apparatus, a pipe machining apparatus, and an adjustment member coupled to the positioning apparatus and a pipe machining apparatus. The adjustment member is configured to move the pipe machining apparatus relative to the positioning apparatus. In one aspect, the pipe machining system also includes a position tracking apparatus configured to identify a position of the pipe machining apparatus relative to a pipe on which the system is mounted.

First claim

The invention claimed is:

1. A pipe machining system configured to machine a pipe, comprising:
a positioning apparatus comprising a body, and a plurality of coupling members provided on the body, each coupling member having a foot configured to engage the pipe and a driven member coupled to the foot and configured to move the foot relative to the pipe;
a pipe machining apparatus configured to be mounted to the pipe and to perform a cutting operation on the pipe;
a plurality of adjustment members coupled to the positioning apparatus and to the pipe machining apparatus, each adjustment member including a driven member configured to move the pipe machining apparatus relative to the positioning apparatus and relative to the pipe;
a position tracking apparatus configured to identify a position of the pipe machining apparatus; and
a controller in communication with the position tracking apparatus, the plurality of coupling members and the plurality of adjustment members for receiving data from the position tracking apparatus, from the plurality of coupling members and from the plurality of adjustment members and for transmitting data to the position tracking apparatus to the plurality of coupling members and to the plurality of adjustment members to cause each driven member to selectively act.

2. The pipe machining system of claim 1 , wherein the position tracking apparatus includes a laser emitter and receiver and a reflective member capable of being engaged by the emitted laser and reflecting the laser back to the laser emitter and receiver, the reflective member being mounted on the pipe machining apparatus.

3. The pipe machining system of claim 1 , wherein each coupling member and each adjustment member further comprises a load cell coupled to the driven member, the load cell being configured to determine a load on the respective coupling member and the adjustment member and transmit information to the controller.

4. The pipe machining system of claim 1 , wherein the driven member of each adjustment member is rotatably coupled to the positioning apparatus, and each adjustment member further includes a ball member attached to the driven member, and an arm engaged with the pipe machining apparatus and the ball member, the arm being configured to be movable relative to the pipe machining apparatus and the ball member.

5. The pipe machining system of claim 4 , wherein the arm of each adjustment member has a curved surface engaged with the pipe machining apparatus.

6. The pipe machining system of claim 5 , wherein the arm of each adjustment member extends from a respective housing of the pipe machining apparatus, and wherein each adjustment member further comprises at least one biasing member mounted between the arm and the respective housing.

7. The pipe machining system of claim 6 , wherein the arm of each adjustment member includes a recess and a socket member mounted within the recess, the ball member of each adjustment member being positioned in the respective socket member, and wherein each adjustment member further comprises a biasing member within the recess and engaged with the socket member.

8. A pipe machining system configured to machine a pipe, comprising:
a positioning apparatus comprising a body, and a plurality of coupling members provided on the body, each coupling member having a foot configured to engage the pipe and a driven member coupled to the foot and configured to move the foot relative to the pipe;
a pipe machining apparatus configured to be mounted to the pipe and to perform a cutting operation on the pipe;
a plurality of adjustment members coupled to the positioning apparatus and to the pipe machining apparatus, each adjustment member including a driven member configured to move the pipe machining apparatus relative to the positioning apparatus and relative to the pipe; and
a controller in communication with the plurality of coupling members and the plurality of adjustment members for receiving data from the plurality of coupling members and from the plurality of adjustment members and for transmitting data to the plurality of coupling members and the plurality of adjustment members to cause each driven member to selectively act.

9. The pipe machining system of claim 8 , wherein each coupling member and each adjustment member further comprises a load cell coupled to the driven member, the load cell being configured to determine a load on the respective coupling member and the adjustment member and transmit information to the controller.

10. The pipe machining system of claim 8 , wherein the driven member of each adjustment member is rotatably coupled to the positioning apparatus, and each adjustment member further includes a ball member attached to the driven member, and an arm engaged with the pipe machining apparatus and the ball member, the arm being configured to be movable relative to the pipe machining apparatus and the ball member.

11. The pipe machining system of claim 10 , wherein the arm of each adjustment member has a curved surface engaged with the pipe machining apparatus.

12. The pipe machining system of claim 11 , wherein the arm of each adjustment member extends from a respective housing of the pipe machining apparatus, and wherein each adjustment member further comprises at least one biasing member mounted between the arm and the respective housing.

13. The pipe machining system of claim 12 , wherein the arm of each adjustment member includes a recess and a socket member mounted within the recess, the ball member of each adjustment member being positioned in the respective socket member, and wherein each adjustment member further comprises a biasing member within the recess and engaged with the socket member.
