Abstract

In one aspect, a tool support for a pipe machining apparatus includes a support arm defining a groove therein and configured to support a tool, and a guide member at least partially positioned in the groove to allow movement of the support arm in a first direction and inhibit movement of the support arm in a second direction. In one aspect, a tool support includes a one-piece unitarily formed body member defining a cavity there through, and a tool support arm at least partially positioned in the cavity and configured to translate within the cavity. In one aspect, a tool support includes a first translating member configured to translate a tool toward and away from a pipe, and a second translating member configured to translate the tool toward and away from the pipe. The second translating member is coupled to and moveable relative to the first translating member.

First claim

The invention claimed is:

1. A tool support for a pipe machining apparatus, the tool support comprising:
a support arm defining a groove therein and configured to support a tool;
a guide member at least partially positioned in the groove to allow movement of the support arm in a first direction and inhibit movement of the support arm in a second direction; and
a body member defining a cavity that includes a first section having a fixed size and a second section having an adjustable size, wherein the body member also defines a receptacle in communication with the first section of the cavity, wherein the support arm is positioned in the cavity and moveable relative to the body member in the first direction, and wherein the guide member is at least partially positioned in the receptacle and extends into the first section of the cavity to be at least partially positioned in the groove;
wherein the body member includes an adjustable portion configured to adjust a size of the second section of the cavity, wherein the adjustable portion is moveable to provide a first size of the second section of the cavity, in which the adjustable portion engages the support arm to secure the support arm to the body member and inhibit movement of the support arm in the first direction, and a second size of the second section of the cavity, in which the support arm is moveable relative to the body member in the first direction, wherein the second size is larger than the first size.

2. The tool support of claim 1 , wherein the first direction is translation of the support arm along a longitudinal axis of the support arm and the second direction is rotation of the support arm about the longitudinal axis.

3. The tool support of claim 1 , wherein the groove is V-shaped and the guide member has a complementary V-shaped.

4. The tool support of claim 1 , wherein the tool support is a pivotal tool support.

5. The tool support of claim 1 , wherein the guide member is moveable to adjust a depth the guide member extends into the groove.

6. The tool support of claim 5 , further comprising an adjustable mechanism useable with the guide member to adjust the depth the guide member extends into the groove.

7. A tool support for a pipe machining apparatus, the tool support comprising:
a one-piece unitarily formed body member defining a cavity there through; and
a tool support arm at least partially positioned in the cavity and configured to translate within the cavity, wherein the tool support arm defines a groove therein;
wherein the body member defines a receptacle in communication with the cavity, the tool support further comprising a guide member at least partially positioned in the receptacle and extending into the cavity where the guide member engages the tool support arm to allow movement of the tool support arm in a first direction and to inhibit movement of the tool support arm in a second direction different than the first direction, and further comprising an adjustable mechanism useable with the guide member to adjust the guide member relative to the receptacle and the groove.

8. The tool support of claim 7 , wherein the tool support is a pivotal tool support.

9. The tool support of claim 7 , wherein the body member includes an adjustable portion configured to adjust a size of the cavity.

10. The tool support of claim 7 , wherein the cavity includes a first section and a second section, wherein the first section has a fixed size and the second section has an adjustable size.

11. The tool support of claim 10 , wherein the body member includes an adjustable portion configured to adjust a size of the second section of the cavity.

12. The tool support of claim 11 , wherein the adjustable portion includes a first resilient member and a second resilient member selectively moveable relative to one another to adjust the size of the second section of the cavity.

13. The tool support of claim 12 , further comprising a first member configured to move the first resilient member and the second resilient member toward one another to reduce the size of the second section of the cavity and a second member configured to move the first resilient member and the second resilient member away from one another to increase the size of the second section of the cavity.

14. A tool support for a pipe machining apparatus, the tool support comprising:
a first translating member configured to linearly translate a tool toward a pipe in a linear direction; and
a second translating member configured to linearly translate the tool toward the pipe in the same linear direction as the first translating member, wherein the second translating member is coupled to and moveable relative to the first translating member.

15. The tool support of claim 14 , further comprising:
a locking member configured to selectively secure the first and second translating members to one another to selectively inhibit or allow movement of the second translating member relative to the first translating member; and
an engagement member coupled to the first translating member to translate the first translating member relative to the pipe.

16. The tool support of claim 14 , wherein the first translating member is configured to translate a tool during a machining operation of the pipe machining apparatus and the second translating member is configured to translate a tool at least one of prior to or subsequent to a machining operation.

17. A tool support for a pipe machining apparatus, the tool support comprising:
a first translating member configured to translate a tool toward and away from a pipe;
a second translating member configured to translate the tool toward and away from the pipe, wherein the second translating member is coupled to and translatable relative to the first translating member; and
a locking member that selectively rigidly secures the second translating member to the first translating member, wherein the locking member is moveable between a first position, in which the first and second translating members are rigidly secured together and are not moveable relative to each other, and a second position, in which the first and second translating members are translatable relative to each other.
