Definitions

  • circular oscillators known from Applicant's "Race 717" machine tools can be used.
  • a radially outwardly of the workpiece to be machined arranged pivot arm is provided, which engages over a ring cross section of a workpiece to be machined by means of a U-shaped bracket, so that at a free end of the bracket held finishing tool can be brought into operative contact with a radially inwardly facing workpiece surface.
  • This design also allows the machining of workpiece surfaces with small radii of curvature.
  • the virtual pivot axis is aligned with a center of curvature or a center of curvature of a workpiece surface to be machined and / or with a curvature center axis of a curved effective surface of the finishing tool or at least substantially aligned, in particular with a deviation of at most 1 mm.
  • the drive device comprises a drive element which drives the finish tool holder along a drive track running concentrically to the guide track. This makes it possible to use the drive means to provide a pivotal position of the finish tool holder along the curved guideway.
  • a distance adjusting device for adjusting a distance between the rotational axis of a rotary drive of the eccentric drive and the virtual pivot axis of the finishing tool holder.
  • the distance setting device allows, for example, the setting of a basic position of the finishing tool holder.
  • the Abstandseinstell Marie is not only used to set up a workpiece machining, but to produce the actual oscillating pivoting movement or for generating a low-frequency movement, which is superimposed on the higher-frequency oscillation movement of the finishing tool ("overlay stroke").
  • a particularly precise guidance of the sheet rail results when the guide elements are in the form of rollers. If a guide element with respect to the curved rail radially inward and two guide elements are arranged radially outwardly relative to the sheet rail, results in a particularly stable arrangement.
  • a device for finish machining a workpiece is designated in the drawing as a whole by the reference numeral 10.
  • the device 10 has a carrier 12 which, in particular, can be fastened, for example, to a cross slide or a robot arm with an upper end in relation to the direction of gravity, and thus can be positioned freely in space.
  • Guiding elements 14, in particular in the form of rollers 16, 18, 20, are provided on support 12, in particular on a lower end of support 12 with respect to the direction of gravity.
  • the rollers 16, 18, 20 are fixed relative to the carrier 12, but rotatably arranged about mutually parallel axes.
  • rollers 16 and 18 are arranged radially outward with respect to a curved rail 22; the roller 20 is disposed radially inwardly relative to the sheet bar 22.
  • the bow rail is recorded between the rollers 16, 18 and 20 without play.
  • the curved rail 22 and the guide elements 14 together form a guide device 54 for guiding the finishing tool holder 26 relative to the carrier 12.
  • the virtual pivot axis 60 is aligned with the center of curvature axis or the center of curvature of a workpiece surface to be machined.
  • the center axis of curvature 32 of the finishing tool 28 also aligns with the virtual pivot axis 60.
  • the connecting rod 50 can also in a bottom dead center (see FIG. 3 ), which corresponds to a lower reversal position of the finish tool holder 26.
