Definitions

  • the invention relates to a method and a device for finishing the outer peripheral surface of slotted, radially outwardly exciting, ring-shaped workpieces, in particular of piston rings combined into a package according to the preambles of claims 1 and 8.
  • DE 30 11 670 discloses such a method and an associated device.
  • the screws are used to adjust the contact pressure of the right Execute half against the left half.
  • the honing rifle adjusts the contact pressure.
  • the disadvantage of this device is based on the fact that when the contact pressure is adjusted, a non-roundness of the Inner bore adjusts itself.
  • the consumption of honing tins is a particular problem in piston ring machining. Due to the large wear of the inner bore of the A large number of tins must be provided for honing tins.
  • the adjustment The honing rifle has proven itself in terms of the quality requirements of modern engines not proven to be useful.
  • the aqueous or oily used Lapping media cause high disposal costs.
  • the invention has for its object the known devices overcome inherent disadvantages and a new finishing process create with which surface topographies can be achieved, in particular the Improve the running properties of piston rings. This task is accomplished through a process and a device according to claims 1 and 8 solved.
  • a closed, locked machining tool is created, which is used for guiding and machining the workpieces.
  • the specific contact pressure is generated by the internal stress of the workpieces.
  • the workpieces are preferably moved axially back and forth and rotated by discs arranged at the end region of the package, it being particularly advantageous that the workpieces are guided in the package with axial play, so that each individual workpiece lies against the grinding belt under its own tension.
  • the discs transmit the rotary motion to the workpieces. The transmission of the rotary movement is initiated in the dead center of the axial back and forth movement.
  • the transmission of the rotary movement to the individual workpieces within the package takes place by means of frictional forces between the individual workpieces. It is also conceivable that the workpieces are specifically axially clamped and relaxed during machining in order to initiate a forced, periodic rotation and thereby to produce a targeted grinding pattern.
  • the speed of the individual movements can be selected so that cross hatching with a predeterminable cross angle and a roughness depth R z of less than or equal to 3 ⁇ m is produced.
  • a wobble movement is initiated during the back-and-forth movement.
  • the workpieces comprehensive tool consisting of at least two segments
  • the Segments have a surface that has a defined radius of curvature It is proposed that the workpieces lay flat Workpieces and tools relatively moved the tool consists of two segments, the Radius of curvature approximately that of a workpiece clamped to the nominal diameter corresponds and on the surface of which an abrasive belt is arranged.
  • the segments are additional the package can be delivered radially via a guide and when the Machining position fixable with fasteners.
  • the disks As the package in the open Processing station is retracted, the usual package infeed via a Insertion cone. This can cause breakouts on the workpieces at the edges can be avoided, the committee is reduced and the quality is improved.
  • an adjustment mechanism acting on the disks are additionally the disks on one Adjustable swivel angle. This setting can be changed during editing become. It would also be conceivable for the disks to be stationary and the processing station to be pivotable, or to use panes with an inclined flat surface.
  • the segments (3, 3 ') are between the disks (7, 7 ') held package (2) radially delivered via a guide (8).
  • this position is locked via Fastening means (9), for example in the form of hydraulic cylinders.
  • Fastening means (9) for example in the form of hydraulic cylinders.
  • a swivel angle ⁇ can be set via an adjustment mechanism (10).
