Definitions

  • the invention relates to a device on spectacle lens edge grinding machines for clamping the spectacle lens according to the preamble of the main claim.
  • Such a device is known from DE-U-85 00 989. It offers the advantage that an exact, angular entrainment of the suction device and thus the spectacle lens is carried out by the half-waves of the device between which the lens is held, and that the suction device has the possibility of adapting to the different curvatures and surface sections of the spectacle lens furthermore a "swimming", ie the sideways sliding of the sucker when fastening it on the glass, is avoided.
  • a holding block for mounting a lens on an edge and angle grinding machine for the processing of eye glasses is known.
  • a holding block provided on its underside with an adhesive layer Application which has three pairs of cams or projections offset by 90 angular degrees from one another, which engage in correspondingly arranged grooves in the push-on sleeve in order to facilitate the alignment of the block.
  • the problem with these known devices is that, as with the device according to DE-U-85 00 989, the teat adapts to the curvature of the glass without slipping (swimming) sideways, and on the other hand that the user easily moves the only and desired rotational position of the suction cup or block relative to the push-on sleeve takes place.
  • the invention provides in a device of the type mentioned in the preamble of the main claim that only one of the radial ribs of the ring of ribs of the suction cup or the adhesive block extending over a circle of 360 ° has a larger or smaller cross section than the neighboring ribs and only one of the recesses of the push-on sleeve has a corresponding cross section which is larger or smaller than the other recesses of the sleeve.
  • the device according to the invention has the advantage that with any inclination of the two half-shafts relative to one another, it is only necessary to turn the suction cup while gently pressing the same against the sleeve until the desired rotational position of the parts relative to one another can thereby be felt, that the only enlarged or reduced parts of the rib ring and the suction cup or block and the recess ring of the push-on sleeve interlock, which ensures the angular position of the suction cup on the glass.
  • all the ribs of the nipple and all the recesses of the push-on sleeve of the device according to the invention have the same width, the one rib of the nipple and the one recess of the sleeve being different in height and depth from the adjacent ribs and recesses.
  • the device according to the innovation has, for example, the design described below.
  • the device according to the invention has the push-on sleeve 1 and the corresponding suction or adhesive block 2, which together form a suction or adhesive block head, which is rotatably connected with the aid of the push-on sleeve to one of the two half-shafts of the spectacle lens edge grinding machine, between which the spectacle lens to be processed is clamped becomes.
  • the section 3 of the push-on sleeve 1 facing away from the sucker or block 2 (at A in FIGS. 2 and 3) has a cylindrical bore 4 with grooves 5, into which an attachment of the spectacle lens holding half-shaft can be inserted.
  • the section 6 of the push-on sleeve 1 widening outwards from section 3 has a cylindrical recess 7 into which the head of the suction device or the adhesive block, which will be described in more detail below, can be inserted. From the wall 8, which delimits the recess 7, a rib 9 extends diametrically through the recess 7, which engages in a corresponding groove 14 of the suction pad or adhesive block and thereby additionally secures the rotation of the suction pad or block relative to the insertion sleeve 1.
  • the section 6 of the push-on sleeve 1 has at the open end of the recess 7 a ring 10 made of radially arranged ribs 11 and radial groove-like recesses 12 lying between them.
  • the cross section of the recess 12a is kept larger than the other recesses of the ring 10. It has a greater depth than the adjacent recesses.
  • the part 2 When the part 2 is designed as a suction cup, in contrast to the metallic or plastic push-on sleeve, it consists of a flexible material and has an upper section 13 in which the groove 14 is arranged, into which the rib 9 of the push-on sleeve can engage.
  • the section 13 is followed by a section 15 of the suction device, which forms a thin, conical and flexible suction edge which is able to adapt to the surface of the spectacle lens and which, when a pressure is exerted in the direction of arrow P on the suction device, is more or less strongly in is deformed in such a way that when the pressure in the direction of arrow P is ended, the edge 15 tries to return to its original position and thereby in the space 16 of the section 14 which is separated from the glass surface, the edge 15 and the wall 13a of section 13 is limited, a vacuum is formed by which the suction cup is held on the lens surface.
  • the top 17 of the edge 15 of the suction cup 2 has a ring 18 of alternating radial ribs 19 and recesses 20.
  • the recesses and ribs are adapted in their radial arrangement and in their spacing and size to the ribs 11 and the groove-like recesses 12 of the push-on sleeve 1, so that these parts intermesh like a comb when the suction cup 2 is assembled with the push-on sleeve 1 to form the suction head.
  • the deeper recess 12a of the push-on sleeve corresponds to a higher rib 19a on the upper side 17 of the suction edge 15 of the suction device 2.
  • the opening width x of the recess 12a preferably corresponds to the opening width of the remaining recesses of the sleeve 1, so that the rim is evenly divided 10 and the rim 18 of the sucker is given.
  • the part is designed as an adhesive block, it has the same configuration of the ring 18 on the upper side 17 of a section corresponding to the suction edge 15, it being possible to dispense with a space 16 in whole or in part.
  • the wall of the adhesive block facing away from section 13 bears in a known manner, a self-adhesive layer or an adhesive film 21 with a tab 22 projecting laterally over the edge of the adhesive block.
  • the recess 12a of the sleeve can also have another shape which is suitable for the angular orientation of the suction pad relative to the sleeve for only one mutual position.
  • a fitting fit of sucker or adhesive block and sleeve is also excluded if, in reverse of the design of the ribs and recesses shown, the one recess 12a of the sleeve is now smaller than the neighboring recesses and the rib 19a of the sucker or block 2 is also smaller than that Neighboring ribs 19 is.
  • the recesses 12 and the recess 12a are of the same depth c, but the recess 12 is wider.
  • the width a is twice the width b of the remaining recesses 12 of the sleeve; it can also make up another whole multiple of the width b of the recesses, so that a uniform division of the edge of the sleeve 1 can be achieved.
  • 6a and 6b also shows that the depth z and the width a can be connected to one another, so that a wide and deep recess is created.
  • the ribs and recesses on the suction cup and the sleeve can also be designed trapezoidal or with curved or curved boundary walls.
