| 61 | MACHINE FOR MACHINING PIPE ENDS, HAVING A CENTERING DEVICE FOR CENTERING A TUBULAR WORKPIECE IN RELATION TO AN AXIS OF ROTATION | US14377552 | 2013-07-31 | US20150321303A1 | 2015-11-12 | Karl-Josef ESSER |
| The invention relates to a machine (1) for machining pipe ends. At least one centering device (8; 35) is associated to said machine, which centering device centers a tubular workpiece (5, 5′) in relation to an axis of rotation (D) of the machine for machining pipe ends extending in the center of the machine, the tubular workpiece either being stationary in the case of a rotating tool head (4) or rotating in the case in which the tubular workpiece is fastened in the machine chuck (9). Precise centering of the tubular workpiece (5, 5′) is quickly and simply achieved in that the centering device (8; 35) has a clamping housing (13; 130) that is open toward the axis of rotation (D), which clamping housing is designed comprising at least three means (14, 15, 16; 140, 150, 160) for contacting the tubular workpiece at the outer circumference and for clamping the tubular workpiece (5, 5′) in a centered manner, which means are circumferentially distributed and adjust mechanically independently of each other to the particular diameter of the workpiece (5, 5′) to be machined. | ||||||
