Definitions

  • the present invention relates to a block piece for Holder of an optical workpiece for its processing according to The preamble of claim 1.
  • the invention relates to a block piece for holding a spectacle lens for their processing, as they are mass-produced in recipe workshops, i.e. Production facilities for the production of individual Eyeglass lenses made of the usual materials (polycarbonate, Mineral glass, CR 39, HI index, etc.) according to recipe Use come.
  • the block piece is first in a predetermined position opposite the protected, already finished surface of the eyeglass lens blank and then in this position the space between block piece and eyeglass lens blank with a molten material (wood-metal or wax) filled. After solidification of the filling material represents the block piece a recording for processing the eyeglass lens blank. Only then can the spectacle lens blanks, depending on the material be prepared by grinding, milling or turning, wherein the previously unprocessed optically effective surface of the respective spectacle lens blank according to their macrogeometry Receive recipe. Then the fine machining of the spectacle lenses, in which the pre-machined optically effective surface of respective spectacle lens receives the desired microgeometry. Depending on u.a.
  • the eyeglass lens is separated from the block piece before finally cleaning steps and possibly further Finishing steps, e.g. an anti-reflective coating or hard coating connect the eyeglass lenses.
  • the block piece remains accordingly, with several processing operations on the spectacle lens and must keep it reliable.
  • Figs. 11 to 14 show a prior art block piece 10, which is designed according to the German standard DIN 58766.
  • the Block piece 10 has an annular base body 12, the cutting made of steel or an aluminum alloy. Starting from a flat, annular end face 14, on the the spectacle lens (not shown) by means of the temporarily deformable Material (not shown) is blockable, the Base 12 on the outer circumference a cylindrical clamping surface 16, over which the blocked on the base body 12 Spectacle lens on a spindle (not shown) of a processing machine is determinable. Close to the clamping surface 16 a conical centering surface 18, which is a flat annular surface 20 at the bottom of the body 12 back rejuvenated.
  • the base body 12 further has a central through hole 22, which can be divided into three longitudinal sections.
  • a first cone surface 24 which extends in the direction the lower annular surface 20 tapers.
  • a second conical surface 26 which extends in the direction the lower annular surface 20 extended, so that the second Tapered surface 26 seen from the end face 14 of an annular Undercut on the body 12 forms.
  • the second Conical surface 26 finally passes over a flat annular shoulder 28 in a third cone surface 30, which is significantly longer than the first and second conical surface 24, 26 and also to extended lower ring surface 20 out.

Consequently is the spectacle lens held in a form-fitting manner on the block piece 10, wherein the fusible material engages behind the second cone surface 26, around the spectacle lens in the axial direction on the block piece 10 and engages the blind holes 36 to the spectacle lens against twisting with respect to the block piece 10 to secure.
  • a disadvantage of this definition of the spectacle lens on the block piece 10, however, is seen to be a result of, albeit low shrinkage of the cooling after the blocking process fusible material to a certain movement between the spectacle lens and the block piece 10 can come, which the machining accuracy is detrimental. More precisely shrinks the fusible material in the area of the first and second cone surface 24, 26 slightly in the direction of the central axis M of the base body 12, so that a small annular gap between the outer periphery of the fusible material and the first and second conical surface 24, 26 may result.
  • the invention is based on the object, a simply trained Block piece for holding an optical workpiece, in particular a spectacle lens, for creating it, on which the optical workpiece by means of the temporarily deformable Materials as reliable as possible and for the fate of the optical Workpiece on the block piece permanently play-free fixable is.
