Abstract
Pipe machining apparatuses are provided. In one aspect, a pipe machining apparatus includes a tool support adapted to both part or completely cut a pipe into multiple portions, and machine a groove in an exterior surface of the pipe. In another aspect, the apparatus has a low radial clearance such that the tool support does not project a significant distance beyond a pipe. In a further aspect, a method of parting and machining a groove in a pipe with a single pipe machining apparatus is provided.
Claims20
A tool support for a pipe machining apparatus, the tool support comprising:
- a base;
- an advancement member adapted to rotate;
- an advancement shaft coupled to the advancement member and adapted to rotate with the advancement member, wherein the advancement shaft includes a threaded portion;
- a roller housing threadably coupled to the threaded portion of the advancement shaft and moveable along the advancement shaft as the advancement shaft rotates;
- a tool housing coupled to and moveable with the roller housing, wherein the tool housing is adapted to support a parting tool and a groove tool;
- a roller adapted to engage an exterior surface of a pipe;
- and
- a stop member engageable by the roller housing and adapted to stop movement of the parting tool and the groove tool in at least one direction.
A pipe machining apparatus comprising:
- a frame;
- a tool carrier coupled to and adapted to move relative to the frame;
- and
- a tool support coupled to and moveable with the tool carrier relative to the frame, wherein the tool support is adapted to support a parting tool and a groove tool, and wherein the parting tool is adapted to part a pipe and the groove tool is adapted to machine a groove into the pipe.
A method of machining a pipe with a pipe machining apparatus, the method comprising:
- coupling a frame of the pipe machining apparatus to a pipe;
- rotating a tool carrier and a tool support coupled to the tool carrier relative to the frame;
- engaging an advancement mechanism of the pipe machining apparatus with an advancement member of the tool support;
- and
- moving a parting tool and a groove tool toward the pipe as a result of engaging the advancement mechanism with the advancement member, wherein the parting tool and the groove tool are supported by the tool support.
