Claims

[Claims for Utility Model Registration] (1) A drive mechanism attached to a base of a size that can be inserted into a pipe, a guide attached to the base so that the drive mechanism can press against the inner surface of the pipe, and a machining head having a machining tool support eccentrically attached to the base body so that the machining tool can be displaced in a predetermined relationship with respect to the inner surface of the pipe by the drive mechanism; What is claimed is: 1. A pipe inner surface machining device comprising: a forward/backward drive mechanism for moving the machining head along the axis; and a rotation drive mechanism for rotating the machining head. (2) The pipe inner surface machining device according to claim 1, wherein the drive mechanism has a swinging mechanism that swings the guide and the processing tool support. (3) The swing mechanism includes a drive cylinder fixed to a base body, and a link disposed between the drive cylinder and a guide and a processing tool support section. The pipe inner surface processing device according to item 2. (4) The pipe inner surface machining device according to claim 1, wherein the machining tool support section has a rotation drive section that rotates the machining tool that is in pressure contact with the inner surface of the pipe. (5) The pipe inner surface machining apparatus according to claim 4, wherein the guide is provided so as to hold the pressure reaction force of the machining tool that presses against the inner surface of the pipe.
