COUPLING MEMBERS AND PIPE MACHINING APPARATUSES INCLUDING COUPLING MEMBERS

摘要

Coupling members and pipe machining apparatuses including coupling members are provided. In one aspect, a coupling member includes a shaft and an engagement member defining a cavity there through and including a projection. The shaft is at least partially positioned within the cavity and extends through the cavity, and the shaft is adapted to rotate relative to the engagement member. The coupling member also includes a plunger at least partially positioned within the cavity and moveable relative to the engagement member, and further includes a biasing member at least partially positioned within the cavity between the plunger and the engagement member.

主权项

1. A pipe machining apparatus comprising:
a first section including a first portion of a frame and a first portion of a tool carrier; a second section including a second portion of the frame and a second portion of the tool carrier, wherein the first section and the second section are adapted to be coupled together, and, with the first and second sections coupled together, the tool carrier is adapted to move relative to the frame; a tool support coupled to one of the first or second portions of the tool carrier and adapted to support a tool for movement with the tool carrier relative to the frame; and a coupling member adapted to couple the tool support to the one of the first or second portions of the tool carrier, the coupling member including a shaft adapted to engage the one of the first or second portions of the tool carrier and an engagement member coupled to the shaft and rotatable relative to the shaft and the tool support between a coupled condition, in which the engagement member couples the tool support to the one of the first or second portions of the tool carrier, and an uncoupled condition, in which the engagement member does not couple the tool support to the one of the first or second portions of the tool carrier.
