である。 In recent years, resin pipes such as plastic or polyethylene have been widely used as gas pipes, and fusion bonding is often employed to join such resin pipes. That is, the end faces of the tubes are heated with a heater to melt them, and the tubes to be joined are pressed together at a predetermined pressure for a predetermined period of time, and then they are allowed to cool and integrate. In this case, in order to reliably join the pipes, it is necessary to cut the end faces of the pipes into uniform vertical flat surfaces prior to the joining operation. The present invention aims to provide a chamfering machine suitable for use in such cases.

た。 However, the conventional chamfering machine is troublesome to attach and detach from the fusion splicer. That is, a carriage that slides along the parallel guide rod of the fusion splicer is provided, and the chamfering machine is pivotally connected to this carriage so that it can rotate freely around a pivot point. Therefore, since it is necessary to install a carriage and it is difficult to remove the chamfering machine from the carriage, for example, when working in a narrow hole at a buried pipe site, it is necessary to rotate the chamfering machine around a pivot point. This presented problems such as the fact that there were cases where the system could not be moved.

External teeth 41A are formed on the outer periphery of the main body 22, and teeth 55A of a gear 55 pivotally supported on the main body 22 by a shaft 53 mesh with the external teeth. Furthermore, the gear 55 is a tooth 4 of a gear 47 that is pivotally supported on the main body 22 by the shaft 51.
7 meshes. The gear 47 itself is the drive gear 4 connected to the output shaft of the motor M attached to the main body 22.
It meshes with the tooth 49A of No. 9. These gear trains serve as reduction gears by appropriately selecting their tooth ratios. By rotating the disc 41 with the motor M, the end faces of the pipes P 1 and P 2 that are pressed against the cutting blades 43 attached to both sides of the disc can be chamfered. The cutting blade 43 is removably attached to cutting blade attachment recesses 42 formed on both sides of the disk 41 by means of set screws 44 . Incidentally, 45 is a handle provided on the main body 22, which serves as a handle when attaching or detaching the chamfering machine or when rotating around the groove 21.
