Claims

[Scope of utility model registration request]

A rotatable headstock having cutter heads at multiple locations in the circumferential direction, the position of the circumferential guide portion being displaced in the axial direction of the headstock, and the annular guide portion being positioned concentrically with the headstock. Each cutter head has an annular guide rail fixedly arranged at the rear of the stock, and a transmission gear rotatably arranged concentrically with the head stock to mesh with a gear of the spindle of each cutter head. The case body is fitted into the fitting hole of the headstock so as to be slidable in the longitudinal direction, the spindle is rotatably held on a bearing inside the case body, and the transmission unit is attached to the rear part of the spindle protruding from the rear end side of the case body. A gear meshing with the gear, a roller holder attached via a bearing to the rear of the spindle that also protrudes from the rear end side of the case body, and a roller rotatably held by the roller holder so as to be guided by the guide section. In the pipe end beveling machine having a body, the spindle is constituted by a front shaft body having a cutter attached to its tip and rotatably held within the case body, and a rear shaft body to which the gear and roller holder are attached. , both shaft bodies can be removably connected via a key and a keyway, and a through hole is formed in the rear shaft body along its axis, and a through hole is formed at the rear end of the front shaft body. Forms a female screw hole, inserts a connecting rod into the through hole, screws its tip into the female screw hole, attaches a nut member to the rear end of the connecting rod protruding from the rear shaft body, and tightens it. A pipe end chamfering machine characterized in that a front shaft body and a rear shaft body are integrally connected by fixing.
