Abstract

Pipe machining apparatuses and methods of operating are provided. In one aspect, a pipe machining apparatus includes an advancement mechanism coupled to a frame and adapted to move relative to the frame between a first position, in which the advancement mechanism is in a travel path of an advancement member and is adapted to be engaged by the advancement member to advance a tool, and a second position, in which the advancement mechanism is positioned out of the travel path of the advancement member and is not adapted to be engaged by the advancement member. In another aspect, a pipe machining apparatus includes multiple motors and pinion gears engaged with a gear rack of a tool carrier. In a further aspect, a pipe machining apparatus includes a race wiper. In yet another aspect, a pipe machining apparatus includes a race lubrication member.

First claim

The invention claimed is:

1. A pipe machining apparatus comprising:
a frame;
a tool carrier coupled to the frame and movable relative to the frame;
a tool support coupled to the tool carrier and adapted to support a tool for movement with the tool carrier relative to the frame, the tool support including an advancement member coupled to the tool to advance the tool; and
an advancement mechanism including a base and a fastener for rotatably coupling the base to the frame, the base is configured to rotate between a first position in which the advancement mechanism is in a travel path of the advancement member and is adapted to be engaged by the advancement member to advance the tool, and a second position in which the advancement mechanism is positioned out of the travel path of the advancement member and is not adapted to be engaged by the advancement member, wherein the base rotates between the first position and the second position about the fastener.

2. The pipe machining apparatus of claim 1 , wherein the advancement mechanism further includes a limiting member coupled to the frame, and wherein the base engages the limiting member when the advancement mechanism is in the first position and is disengaged from the limiting member when the advancement mechanism is in the second position.

3. The pipe machining apparatus of claim 1 , wherein the advancement mechanism further includes a guide member moveably coupled to the base, an adjustable coupling member for coupling the guide member to the base, a biasing member adapted to apply a biasing force to the guide member, wherein the coupling member is adjustable between a coupled condition, in which the guide member is fixed relative to the base, and an uncoupled condition, in which the biasing member is adapted to move the guide member relative to the base.

4. The pipe machining apparatus of claim 3 , wherein the biasing member is adapted to move the guide member away from the frame when the coupling member is in the uncoupled condition.

5. The pipe machining apparatus of claim 1 , wherein the advancement mechanism further includes a finger assembly coupled to the base, wherein the finger assembly includes
a housing defining a cavity,
an engagement member at least partially positioned within the cavity and adapted to engage the advancement member of the tool support, and
a biasing member positioned between the housing and the engagement member, wherein the biasing member is adapted to bias the engagement member in a direction out of the cavity;
wherein engagement between the engagement member and the advancement member moves the engagement member against the biasing member and into the cavity and disengagement between the engagement member and the advancement member moves the engagement member in the direction out of the cavity under bias from the biasing member.
