    vibration
    The invention relates to a vibration damper for use in the turning of workpieces with cavities. For example, occur during threading at the end of large pipes vibrations, which cause unwanted vibration marks or chatter marks. In addition, the vibrations have a negative effect on tool wear and machining quality. It is known to close the pipe ends with elastic plugs, which can cause a certain damping within narrow limits. Frequently, however, the achieved damping effect is not sufficient, which is why, depending on the wall thickness of the workpieces, the cutting parameters must be adjusted in order to achieve the desired manufacturing quality. This procedure usually extends the cycle time and shortens the tool life, since optimal cutting parameters can no longer be used.
    It is the object of the present invention to provide a vibration damper for the machining of workpieces with cavities.
    This object is achieved with a device according to claim 1. Advantageous embodiments are the subject of the dependent claims.
    According to an advantageous aspect of the invention, the vibration damper is provided with a spanned by a threaded spreader, which is pressed over two clamping cone against the pipe inner wall. Due to the shape of the expansion element and clamping cone, pressing zones form between the expansion element and the inner wall of the pipe. This prevents tilting of the vibration damper in the pipe. The flat contact of the expansion element on the tube inner wall ensures the damping. About the variation of the tightening torque of the threaded spindle, a desired preload can be adjusted. With suitable change parts, expansion element and clamping cone can be adapted to the inner diameter of different workpieces.
    In this way, the vibrations are independent of the wall thickness of the '' 20
    Workpiece reliably damped, so that you can work with optimal Schnittparamclcrn. Because the face of the workpiece is in the process of being machined must be freely accessible, the Schwmgunysdämpfer is placed in automated machines by a detachable setting in the end of the tube and stretched and released after processing and removed from the tube. Placing, removing, clamping and relaxing can also be done manually. The introduction of the torque for tightening or loosening and the axial securing position of the vibration damper by means of a non-positive or positive connection.
    A scraper arranged on the front side of the vibration damper reliably removes chips or coolant residues from the workpiece.
    The invention will be explained in more detail below with reference to an exemplary embodiment.
    Show it:
    1 shows the vibration damper in the untensioned state. FIG. 2 shows the vibration damper in the tensioned state
    1 shows the unstressed vibration damper in the end region of a tube 1. The main body 2 comprises a cylindrical surface and a conical portion with a conical surface 13. On the left side of the base body 2, the setting unit 4 is arranged. This comprises a setting rod 11 and an anti-rotation 12. About the setting rod 11, the setting unit 4 can be coupled to the vibration damper. In the bore of the base body 2, the hollow shaft 3 is arranged with the threaded spindle 17. At this a self-locking saw thread 14 is provided for the nut 7. The hollow shaft 3 is set on the setting rod 11 in rotation. In this case, the nut 7 shifts the sliding cone 5 towards the conical surface 13 in order to spread the expansion element 6. The rotation 12 prevents rotation of the base body 2 when the hollow shaft 3 rotates. The vibration damper is used with the setting unit 4 in the tube 1 and removed from this again. In the bore in the hollow shaft 3 is the shutter 9, which is pressed by the spring 10 in the closed position (Fig. 2). 1, the Vcrsehlussschiobor 9 was against the 20th
    Spring force shifted to the right.
    2, the vibration damper is shown in the tensioned state. The sliding cone 5 was moved by the nut 7 to the conical surface 13 out. As a result, the expansion element 6 was pressed against the inner walls of the tube 1, so that its vibrations are reliably prevented. The first and second keys 8, 15 prevent the nut 7 from rotating with the threaded spindle 17. By selecting a suitable torque, the desired preload can be adjusted. The setting unit 4 has been uncoupled, so that the tube 1 is freely accessible from the front side. The shutter 10 is in the closed position. The arranged on the front side of the vibration damper scraper 16 removes chips or coolant residues safely from the tube first
