  • Patent number: 9919387
    Abstract: A differential device including a planetary gear mechanism having a sub-gear, an annular gear and a planetary gear is more compact than a differential gear using a bevel gear mechanism. Since revolution torque of the planetary gear is transmitted to a free gear, and torque from the main gear is reduced to be transmitted, the differential device can use a small-sized drive unit in comparison with a conventional one. Hence, a machining apparatus including such a differential device is also compact. If the machining apparatus has three drive units, a pair of ring gears, first and second power transmission shafts, a radial movement mechanism and an axial movement mechanism, a tool holder, namely, a tool coupled to the radial movement mechanism and the axial movement mechanism, can be freely moved in axial and radial directions with respect to the pipe.

  • Patent number: 8935973
    Abstract: In an improvement to a pipe re-facing machine having a rotatable flange plate and a coaxially-mounted collar rotatable with and longitudinally movable relative to the flange plate, a support bracket projects from the flange plate, and a support block is retainingly mounted to and movable relative to the support bracket in an angled radial direction. The support block is adapted to receive a tool holder carrying a cutting element. An actuating mechanism is engageable with the support block such that longitudinal movement of the collar will move the support block relative to the support bracket. The actuating mechanism can thus move the cutting element in an angled direction relative to the axis of a tubular workpiece, thereby enabling machining of a bevelled edge on an annular shoulder of a tubular workpiece non-rotatably mounted to the re-facing machine by longitudinally moving the collar while rotating the flange plate.

  • Patent number: 8245610
    Abstract: A device for cutting bar-shaped or tubular workpieces (1, 27), for example a peeling machine, is presented, in which, for the first time, the advance of the tools (7, 26, 44, 46) is brought about by a relative rotation between a toolholder (3, 25, 45) carrying the tools (7, 26, 44, 46) and an advancing sleeve (4, 24, 47). The toolholder (3, 25, 45) and advancing sleeve (4, 24, 47) are driven via gearwheels (19, 18) arranged on the same gear shaft (17) and having an oppositely oriented helical toothing. By means of an axial movement of the gear shaft (17), a relative rotation between the toolholder (3, 25, 45) and advancing sleeve (4, 24, 47) is achieved on account of the helical toothing. Moreover, it is proposed to use milling cutters (26, 44) as tools.

  • Publication number: 20120067180
    Abstract: The invention relates to a tube machining device for machining the end of a tube, the tube machining device having an inner clamping unit with clamping wedges, which can be moved radially in relation to an axial longitudinal axis of the tube machining device relative to the tube to be machined for releasably fixing the inner clamping unit on the end region of a tube to be machined. Furthermore, a tool receiving unit for receiving a tool is provided, wherein the tool receiving unit is arranged concentrically in relation to the axial longitudinal axis and is mounted rotatably about this longitudinal axis relative to the inner clamping unit. To prevent foreign bodies from unintentionally falling into the tube to be machined and being lost there during the machining of the end of the tube, according to the invention the tube machining device also has a sealing body that can be introduced with the inner clamping unit into the end region of the tube to be machined.
