Tool holder and pipe machining tool

Abstract

A skiving apparatus is provided for at least partial removal of the surface of an least approximately tubular body having a center axis, in particular of a plastic pipe, comprising a clamp assembly having a center axis and at least one clamp member for clamping the skiving apparatus to the tubular body, a skiving assembly comprising a skiving arm unit, a skiving knife arrangement disposed at a first end of the skiving arm unit, and a skiving arm support that connects the clamp assembly to the skiving arm unit. The skiving arm unit is connected by its first and second ends to the skiving knife arrangement and the skiving arm support and is pivotable in the common plane with the center axis of the clamp assembly in such a way that the skiving knife arrangement keeps its orientation relative to the center axis of the clamp assembly in every pivoted position of the skiving arm unit. A clamp assembly as a tool holder for a tool such as a skiving tool is also provided, for machining an approximately tubular body having a center axis, in particular a plastic pipe, having a center axis, a mandrel disposed coaxially with the center axis of the clamp assembly, and at least one clamping device disposed on the mandrel and directed substantially radially outwards.
