Abstract
Pipe machining apparatuses, tool supports, and methods of operating pipe machining apparatuses are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier coupled to and movable relative to the frame, and a tool support coupled to and movable with the tool carrier relative to the frame. The tool support is adapted to support a tool and move the tool in a first direction toward a pipe at a first increment and move the tool in a second direction away from the pipe at a second increment. The second increment is larger than the first increment.
Claims8
A method of operating a pipe machining apparatus, the method comprising:
- fixedly coupling a frame of the pipe machining apparatus to a pipe, the frame defining a circumference;
- rotating a tool carrier circumferentially relative to the frame;
- moving a tool relative to the tool carrier in a first linear direction and toward the pipe at a first increment;
- and
- moving the tool relative to the tool carrier in a second linear direction and away from the pipe at a second increment larger than the first increment.
A method of operating a pipe machining apparatus, the method comprising:
- fixedly coupling a frame of the pipe machining apparatus to a pipe;
- moving a tool carrier relative to the frame, wherein the tool carrier is movably coupled to the frame;
- providing a tool clamp adapted to support a tool, wherein the tool clamp is coupled to the tool carrier and movable with the tool carrier, and wherein the tool clamp is movable relative to the tool carrier;
- moving a worm gear to a first position;
- coupling the worm gear with a feed screw in the first position;
- rotating the worm gear in a first worm gear direction to rotate the feed screw and thereby moving the tool clamp and tool along the feed screw to move the tool clamp and tool in a first tool direction at a first increment upon rotating the worm gear in the first worm gear direction;
- rotating the worm gear in a second worm gear direction to rotate the feed screw and thereby moving the tool clamp and tool along the feed screw to move the tool clamp and tool in a second tool direction at the first increment upon rotating the worm gear in the second worm gear direction;
- moving the worm gear to a second position;
- uncoupling the worm gear from the feed screw in the second position;
- and
- rotating the feed screw independently of the worm gear with the worm gear in the second position to move the tool clamp and tool along the feed screw to move the tool clamp and tool in the second tool direction at a second increment larger than the first increment.
A method of operating a pipe machining apparatus, the method comprising:
- fixedly coupling a frame of the pipe machining apparatus to a pipe;
- moving a tool carrier relative to the frame, wherein the tool carrier is movably coupled to the frame;
- moving a tool relative to the tool carrier and toward the pipe at a first increment, wherein the tool is movably coupled to the tool carrier;
- wherein prior to moving the tool relative to the tool carrier and away from the pipe at the first increment;
- and
- thereafter moving the tool relative to the tool carrier and away from the pipe at a second increment larger than the first increment.
