  • the finishing stone is in one Swivel device clamped, the swivel axis in the The center of curvature of the surface to be machined lies. It has been shown that with such devices only a limited number of workpieces can be machined can. Workpieces with slightly curved surfaces, i.e. with surfaces whose radius of curvature is very large can not be processed with such devices because the swivel arm for swiveling the finishing stone in the Is usually too short. This is especially true for angle-adjustable floating bearings and large spherical roller bearings. In addition, CNC processing machines are known with which Machining tools, e.g. Drills, turning tools and the like in the Space can be moved.
  • Machining tools e.g. Drills, turning tools and the like in the Space can be moved.
  • Such machines are not suitable for tools which the workpiece is not punctiform or linear flat, namely processed via a finishing stone.
  • This finishing stone does not only have to be in relation to the tool the X-Y plane but also exactly in its angular position be positioned so that the cutting surface of the Finishstones flat on the surface to be machined Surface of the workpiece rests.
  • the invention is therefore based on the object To provide device with which such Workpieces can be processed relatively easily.
  • This task is accomplished with a finishing device at the beginning mentioned type solved according to the invention in that the Holder by means of a swiveling device around the X-Y plane orthogonal virtual swivel axis swiveling is stored and that to the position of the finishing stone corresponding swivel angle of the holder over the Computing means can be determined and the swivel device from the control unit can be controlled.
  • the finishing stone about the drive device not only in the X-Y plane process but also pivoted such that the Finish stone permanently flat on the one to be processed Surface rests.
  • the to every position of the finishing stone Corresponding swivel angle is calculated using the computing means from the geometry of the surface to be machined or calculated from the profile of the workpiece. This requires in the rule of two points and the radius of curvature of the Surface. From this information the virtual Swivel angle calculated by which the finishing stone is only pivoted. Because this virtual Swivel angle a very large distance to finishing surface via the drive device in the X direction and in the Y direction procedure and in addition to an actual one Swivel axis swiveled.
  • the Swivel device integrated in the drive device. So the finishing stone is in via the drive device Move X and Y direction, which is done by the swivel device via the drive device is moved on which the holder for the finishing stone is provided. In addition, the swivel device the holder and thus the finishing stone swiveled.
  • the Swivel device is machine-proof, and in the A drive device is provided, which the holder for the finishing stone in two to each other orthogonal directions.
  • this swiveling device can be electrically e.g. via servo motors or the like, electromagnetic, can be activated hydraulically and / or pneumatically.
  • this swivel device has an oscillator on which the holder can be moved oscillating can.
  • the device according to the invention is suitable for level and curved surfaces as well as concave and convex Machining surfaces.
  • surfaces be edited that are inclined so that the virtual Pan axis outside the plane of the rule annular component.
  • a further training provides that the holder and / or the Drive device a pressure device for the Has finishing stone.
  • This pressure device holds the Finish stone permanently on the surface to be processed and drives it with a given force. On in this way the desired removal is achieved and the Compensation for wear on the finishing stone.
  • the pressure device is pneumatic or hydraulic loadable, the finishing stone also with spring force can be pressed onto the surface to be processed.
  • a pneumatic device has the main advantage that the contact pressure is kept relatively constant relatively easily can be.
  • the device according to the invention is like this in one variant executed that the actual pivot axis in the Contact level of the finishing stone and the one to be machined Surface lies.
  • the actual swivel axis lies between the Touch level and the location of the virtual swivel axis.
  • the position of the actual pivot axis is preferred adjustable with regard to the surface to be processed.
  • FIG. 1 shows an overall designated 1 Finishing device with a machine housing 2, in which Supply units, drives, a control unit 23 with Computing means and the like for the device 1 housed are.
  • a carriage 3 on the machine housing 2 on a vertical guideway 4 in the Y direction (Double arrow 5) is movable.
  • a support arm 6 There is 3 on this carriage attached to a support arm 6 a swivel device 7, on which a swivel arm 8 about a swivel axis 9 is pivotally mounted.
  • This swivel device 7 is Can be moved in the vertical direction via the slide 3.
  • Between the swivel device 7 and the support arm 6 there is another carriage 10, over which the Swivel device 7 in an orthogonal to the plane of the drawing Direction, namely in the direction of the x-axis, is movable.
  • a Face plate 12 is a workpiece via holding devices 13 14 attached, which are rotated about the axis of rotation 11 can.
  • the axis of rotation 11 and the central axis lie here of the workpiece 14 coaxially with each other.
  • the swivel arm 8 has the shape of a U open at the bottom and engages its free end into the workpiece 14.
  • This Free end 15 is a holder 16, which one Finish stone 17 picks up.
  • This finishing stone 17 attacks of the inner surface 18 to be machined (FIG. 2).
  • On the finishing stone 17 lies flat over this inner surface 18 on. So he has the same on his contact surface Curvature like the inner surface 18.
  • the two slides 3 and 10 form one Drive device 22 for the holder 16 and the Finish stone 17 in the X direction 20 and in the Y direction 5.
  • the finishing device 1 is in plan view in Direction of arrow II shown in Figure 1. It is clearly recognizable how the finishing stone 17 on the Inner surface 18 abuts.
  • the holder 16 has one Pressure device 19, via which the finishing stone 17 with constant force is pressed onto the inner surface 18.
  • the pivoting device 7 in is moved over the slide 10 Direction of double arrow 20, i.e. Move in the X direction.
  • the two slides 3 and 10 thus allow the descent the inner surface 18 of the workpiece 14 in the x-y plane 21.
  • About the pivoting device 7 is also the Finished stone 17 pivoted about the pivot axis 9, so that it is permanently flat on the inner surface 18 is present.
  • the pivot axis 9 is at a distance from Inner surface 18.
  • Swivel arm 8 there is also the possibility that the pivot axis 9 exactly in the interface between the inner surface 18 and the finishing stone 17 is coming.
