Definitions

  • the invention relates to a carrying device for a plurality of feed for fine grinding and / or polishing surfaces optically Components, the feed chuck with a vacuum / air connection is provided and the support device a spindle shaft with a central bore for vacuum / air supply.
  • a feed of the type mentioned for single lens processing is known from DE 198 12 186 A1.
  • a carrying device with several such feed is described in DE 100 03 291.5.
  • the Carrier consists of a base body and a cover part.
  • Several of the feed chucks are embedded in the cover part elastic support elements included as lens pads.
  • the Support elements are connected to the vacuum / air supply overlying surfaces of the optical components to be machined customized.
  • the top of the lid is spherical to the radius of a grinding or Adjusted polishing cap.
  • the components in the feed such as. convex or concave lenses, are characterized by the Support elements with the surface to be machined against the grinding or Polished caps pressed.
  • the feed with the elastic Support elements can be firmly inserted into the cover part. It can but also rotatable in the cover part via a cylindrical holder be stored. Several can be symmetrical to the spindle axis Receiving food can be kept in the lid part.
  • the cover part can be exchangeably attached to the base body be to adapt the system to different radii of the To allow grinding or polishing spheres.
  • the material and The time required to manufacture the cover parts is considerable, not only Cover parts for different machining radii, but also for different diameters of the feed are provided have to. This increases the storage volume.
  • the setup times for that Replacing the cover parts are particularly important for small ones Machining series not to be neglected.
  • the invention was therefore based on the object while maintaining the Multiple arrangement of feed chucks of the type described Accelerate adaptation to different machining radii and the effort for stocking feed intake reduce.
  • the stakes in the arms can be easily attached to the fasteners commercially available intake chucks with elastic support elements for Individual lens processing can be adjusted.
  • the angle adjustment of the Arms allows quick adjustment of the position of the Intake chuck against different radii of grinding or Polierkalotten. Through a suitable construction of the angle adjustment the arm position can be both convex and concave Grinding or polishing spheres are adjusted. About the size and Number of arms is an easy adjustment to feed intake different diameters possible.
  • An advantageous embodiment of the angular adjustment includes one of the spindle shaft height-adjustable support plate, on its circumference several upright supports are attached.
  • the head of the Spindle shaft has a circumferential groove. The poor will on the one hand swiveling on the supports and on the other hand movable supported in the groove.
  • By adjusting the support plate the bearings on the supports continuously from a position above in a position below the groove. The direction of the Axes of the feed in the inserts changed increasingly away from the spindle axis.
  • the carrying device shown in FIG. 1 contains a spindle shaft 1, on the drive shaft of a grinding or not shown Polishing machine can be put on.
  • the spindle shaft 1 is with an external thread 2, on which a support plate 3 and one Lock nut 4 are screwed on.
  • the spindle shaft 1 contains one central bore 5 for vacuum / air supply.
  • the shaft 7 together with a disc 8 a circumferential groove 9 on the head of Spindle shaft 1 forms.
  • the support plate 3 is designed as a circular disc, on its circumference has four mutually symmetrical flats 10, such as can be seen from the illustration in FIG. These flattenings 10 supports 11 are screwed. At their free end, the Supports 11 a bearing bore 12 for receiving a bearing axis 13 on, as can be seen from the illustration in FIG. It is recognizable that depending on the diameter of the not shown Intake feed a different number of flats 10 and Supports 11 can be arranged on the support plate 3.
  • Arms 14 are pivotable on the supports 11 via the bearing axles 13 hinged.
  • the arms 14 point at their in Fig fork-shaped end also bearing holes 12 'to the Bearing bore 12 of the supports 11 are arranged in alignment.
  • a stepped cut 15 provided that is adapted to the radius of the disc 8 and with the the arms 14 engage in the groove 9 on the head of the spindle shaft 1.
  • An insert 16 is provided in the surface of the arms 14, in which e.g. commercial feed not shown for Single lens processing can be screwed in.
  • the stakes are closed on the back with a cup-shaped cylinder 17 a flexible vacuum / air line 18 for connection to the Bore 5 in the spindle shaft 1 is connected.
  • the axis 19 of the inserts 16 directed towards the axis 20 of the spindle shaft 1.
  • the bearing axis 13 is located above the groove 9, so that it is a Working position in cooperation with a convex grinding or Polishing dome acts.
  • the support plate 3 on the Spindle shaft 1 can be turned down.
  • the arms 14 run with their milling 15 in the groove 9 about the axis 20 of Spindle shaft 1 around.
  • the flexible vacuum / air line 18 can to be released from the cup-shaped cylinder 17.
  • the axis 19 of the inserts 16 is more and more of the Axis 20 of the spindle shaft 1 directed away and finally goes in a working position for interacting with a concave Grinding or polishing dome over after also working for plane surface processing has been carried out.
  • the one described Carrying device has particularly in the processing of Proven lens surfaces with a radius of at least ⁇ 50 mm.
  • the accuracy of the angle adjustment of the arms 14 depends from the pitch and the game of the thread of the support plate 3 in Male thread 2 from.
  • a feed chuck with elastic support elements are deviations between the Angular position of the surface of the optical component to be machined and the Surface of the grinding or polishing tool but over a larger one Tolerance range balanced.
