Definitions

  • the invention relates to a device for double-sided fine machining or superfinishing of disk-shaped workpieces or workpiece surfaces with a planar and / or spherical surface.
  • the invention has for its object to develop a device of the type mentioned so that disk-shaped workpieces can be optimally processed on both sides at the same time.
  • the device for double-sided fine machining or superfinishing of disk-shaped workpieces with flat and / or spherical surfaces has means for receiving the workpiece and is also provided with a first tool rotatably received in a first tool spindle for machining one Surface of the workpiece, wherein the first tool spindle is rotatably received in a first orbital spindle and the axis of the first tool spindle and the axis of the first orbital spindle are at a first distance from one another, with a second tool rotatably received in a second tool spindle for machining the other surface of the Workpiece, wherein the second tool spindle is rotatably received in a second orbital spindle and the axis of the second tool spindle and the axis of the second orbital spindle are at a second distance from one another, and during processing d both orbital spindles and both tool spindles are rotated in the workpiece.
  • disk-shaped workpiece surface e.g. End faces of bores understood in a housing, e.g. Pump housing are provided.
  • a housing e.g. Pump housing
  • disk-shaped workpieces can be processed in a simple and quick manner.
  • the device according to the invention leads to minimal deformations of the workpiece, which is reflected in very narrow machining tolerances.
  • Various micrographs can be produced with the device according to the invention, in particular a cross-cut can be produced.
  • the means for receiving the workpiece receive the workpiece on its edge surfaces.
  • the means for receiving the workpiece preferably form a three-point or three-line bearing.
  • a collet is used to hold the workpiece.
  • the holding means grips the workpiece on its edge surface, so that the end faces to be machined are freely accessible.
  • the workpiece is held against rotational movements, radial misalignment and the like via the holding means. captured.
  • the equipment of the device according to the invention and the Workpieces can be removed fully automatically, for example using a turret holder or a linearly movable holder.
  • the directions of rotation of all spindles are the same. This has the advantage that devices for reversing the direction of rotation can be dispensed with within the spindle drives.
  • the directions of rotation of the first tool spindle and / or the first orbit spindle is not the same as the directions of rotation of the second tool spindle and / or the second orbit spindle. This configuration enables a large number of different superfinishing processes to be carried out.
  • first tool and / or the second tool can be adjusted from both sides of the workpiece, in particular hydraulically, pneumatically or via an NC control, enables fully automatic operation.
  • control drive can be easily integrated into conventional machines.
  • Optimal work results are achieved in that the axes of the two tools are offset from one another by an angle different from 0 °, in particular by 90 °. On in this way, only one tool acts on sections of the workpiece and both tools act on other sections of the workpiece simultaneously. In addition, none of the tools acts on other sections of the workpiece, so that these sections can be cleaned and / or cooled.
  • the axes of the tools advantageously run around the center of the workpiece, in particular in a circular manner.
  • the angular offset of the two tools is preferably constant during the rotational movement of the tools around the center of the workpiece. In this way, optimal machining conditions, in which high cutting performance, tight tolerances, optimal surface quality, etc. are achieved, are maintained.
  • the axes of the tool spindles are coupled mechanically or electronically. With electronic coupling there is also the possibility that the process can be intervened in a targeted manner, e.g. initiated by in-process measuring devices.
  • the axes of the orbital spindles can be coupled to one another mechanically or electronically.
  • the axis of the tool spindle has an adjustable angle other than 0 ° to the axis of the orbital spindle.
  • the workpiece can be provided with plane-parallel end faces, or one or two convex or concave curved end faces can be machined on the workpiece.
  • the axes of the orbital spindle can have an angle to one another which is adjustable in the horizontal and / or vertical plane and is different from 0 °.
  • the tool is preferably a cup grinding wheel or a slip ring. This has the advantage that the surface of the tool that engages the workpiece is at a substantially constant distance from the axis of rotation of the tool spindle compared to a grinding wheel that is in full contact with the workpiece.
  • the axis of the first and / or second orbit spindle preferably runs through the center of the workpiece.
  • the orbital spindles are coaxial with one another and are at a distance from the center of the workpiece. This configuration enables further variations in the finishing process.
  • An additional Variation is achieved in that the rotational speed of at least one of the spindles is variable.
  • orbit spindles 1 and 2 of a superfinishing machine (not shown in more detail). These orbital spindles 1 and 2 have axes 3 and 4 about which they can be rotated. The drive of the orbit spindles 1 and 2 is not shown and is located within the housing 5.
  • Tool spindles 6 and 7 are attached to the orbital spindles 1 and 2, the axes of rotation 8 and 9 of which are each at a distance 10 and 27 from the axes 3 and 4 of the orbital spindles 1 and 2.
  • Tools 11 and 12 are fastened to the tool spindles 6 and 7 coaxially to the axes 8 and 9.
  • the spindles 1 and 2 as well as 6 and 7 as well as the tools 11 and 12 rotate in the direction of the arcuate arrows drawn around the axes 3 and 4 and 8 and 9.
  • the tools 11 and 12 are designed as cup grinding wheels 13 and 14.
  • a disk-shaped workpiece 17 which is held in place by a workpiece holder, which is only indicated by three arrows 18, on its peripheral edge 19.
  • This workpiece 17 has parallel end faces that are machined by the two tools 11 and 12 in a plane-parallel manner.
  • the workpiece 17 can also be provided with one or with two concave or convex curved end faces, which are machined using the two tools 11 and 12.
  • the two axes 3 and 4 of the orbital spindles 1 and 2 are angularly adjustable in the horizontal plane and in the vertical plane in the direction of the arrows 20 and 21 or in their opposite direction.
  • the axis 8 of the first tool spindle 6 is the axis 3 of the first orbital spindle 1 and accordingly the axis 9 of the second tool spindle 7 is the axis 4 of the second Orbital spindle adjustable in angle.
  • Axes 3 and 8 or 4 and 9 can intersect or skew to each other.
  • FIG. 2 shows the two tools 11 and 12 and the workpiece 17.
  • the center of the workpiece 17 is designated 22.
  • the axes 3 and 4 of the two orbit spindles 1 and 2 also run through this center 22.
  • the two center points of the workpieces 11 and 12 are designated by 23 and 24, the axes of rotation 8 and 9 of the tool spindles 6 and 7 being designated by these center points 23 and 24 to run.
  • the axes of rotation 8 and 9 of the tool spindles 6 and 7 and of the tools 11 and 12 move on an orbit 25 or on a circular orbit which has a diameter 26.
  • the diameter 26 corresponds approximately to twice the distance 10 or 27 of the axes 3 and 8 of the spindles 1 and 6 or the axes 4 and 9 of the spindles 2 and 7.
  • the size of the tools 11 and 12 is selected so that the area in which both tools 11 and 12 act simultaneously on both end faces of the workpiece 17 is essentially in the area of the center point 22.
  • One-sided loads, which could possibly lead to deformations, are avoided in this way.
