Definitions

  • the invention relates to a receiving chuck for receiving optical lenses and other optical components during fine grinding and polishing, with at least one lens support surface made of elastic material and a channel arrangement for supplying or removing air or other flowable media from the area not to be processed Back of lens.
  • Fine grinding and polishing are carried out after pre-grinding.
  • Fine grinding and polishing use grinding pastes that are placed between a tool that has the shape of a spherical cap and the lens surface to be machined.
  • the pressure of the tool deforms the lenses more or less.
  • Thin lenses are deformed relatively strongly, i.e. those in which the ratio between lens diameter and lens thickness is large.
  • the working pressure creates a so-called aspheric bending, which results in inaccuracies in the lens surface.
  • the invention has for its object to provide a chuck of the type mentioned in such a way that the working pressure of the tool is absorbed so that aspheric bending is avoided as far as possible.
  • the lens support surface has at least two support zones, each support zone being assigned its own channel system in such a way that the pressure in each support zone can be set independently of the pressures in the other support zones.
  • the ability to regulate the support pressure zone by zone also allows larger working pressures, which significantly increases the machining time Lich can be reduced.
  • the intake chuck according to the invention is particularly suitable for processing sensitive lenses with a large diameter / thickness ratio. When using the feed according to the invention, the work result is easily reproducible from processing to processing.
  • the lens support surface is formed by a membrane covering the entire back of the lens (claim 2).
  • This embodiment has the advantage that a seal does not have to be provided between the back of the lens and the lens support, since the support pressure is regulated on the side of the membrane that is free from the back of the lens.
  • the support zones are preferably arranged concentrically to one another. This arrangement is most useful for circular lenses with spherical surfaces, but the support zones can also be arranged differently from a concentric arrangement for special lens shapes.
  • the membrane thickness can be different in the different support zones (claim 4), e.g. it can be thicker in an inner support zone than in an outer support zone (claim 5). This has the advantage that the membrane can still be adapted to certain support forces in certain zones of the workpiece. For a given material, the bending characteristic depends on the membrane thickness.
  • the membrane can be attached particularly cheaply if it has clamping edges according to claim 6. Such clamping edges result in a form-fitting engagement of the membrane in other parts of the receiving chuck, whereby an axial migration of the membrane is avoided with certainty.
  • the receiving chuck preferably has a centering edge which interacts with the peripheral surface of the lens (claim 7). This results in a lateral fixation of the lenses without having to be sucked or glued to their base. If the centering edge consists of elastic material (claim 8), the centering pressure is distributed over the circumference of the lens, thereby avoiding so-called oval fitting errors.
  • the centering ring is integrally formed on the membrane and can be expanded when the membrane is pressurized. This gives you a clamp. In the expanded state, the lens can be inserted comfortably and, after the pressure has been reduced, is centered precisely with elastic pressure on the centering edge.
  • the invention can be used both for intake chucks for only one lens and for intake chucks for the simultaneous intake of several lenses.
  • An advantageous constructive design for feed for only one lens is specified in claims 10 to 12.
  • An advantageous embodiment for a multiple feed is specified in claims 13 and 14.
  • the receiving chuck A 1 according to FIG. 1 is rotationally symmetrical to its axis 1.
  • the receiving chuck has a base body 2, a surrounding ring 3, a membrane holding ring 4, a membrane 5 and a membrane holding plate 6. The design and the interaction of these main components is described in detail below.
  • the base body 1 has a shaft 7 with which it can be attached to a fine grinding and polishing machine.
  • the base body 2 has a flat end surface 8.
  • the end surface 8 there are two annular grooves in which elastic sealing rings 9 and 10, namely so-called O-rings, are accommodated.
  • elastic sealing rings 9 and 10 In the area between the two mutually concentric sealing rings 9, 10 8 channels 11 open on the surface, which emanate from a collecting space 12 located in the base body.
  • a body 14 is screwed into the bore 13, which is provided with an internal thread, and has a continuous channel 15 in its center.
  • the membrane retaining ring 4 lies with a flat lower surface 16 on the surface 8 of the base body and is pressed against the surface 8 by the surrounding ring 3.
  • the encircling ring 3 has an inner shoulder 17 which presses on an annular projection 18 of the membrane holding ring 4.
  • the surrounding ring 3 is pressed onto the base body 2.
  • the press seats are at 19.
  • the membrane retaining ring 4 has on its lower surface 16 a flat annular groove 20 which, together with the surface 8, form an annular channel into which the channels 11 open.
  • annular projection 20 From the annular groove 20 go channels 21 which open on the upper end surface 22 of the membrane retaining ring. There is an outer circumferential groove 23 on the membrane retaining ring, which is bounded at the bottom by the annular projection 18 and at the top by an annular projection 24.
  • the annular projection 24 has a smaller diameter than the annular projection 18.
  • the membrane 5 has a central part 25 of relatively large thickness s 1 and an annular outer part 26 concentrically surrounding the central part, of smaller thickness s 2 .
  • the front side 27 of the membrane supports the rear side 28 of the lens L 1 over its entire extent.
  • Two annular walls protrude from the back of the membrane, namely an outer wall 29 and an inner wall 30 which is concentric with the outer wall. The radial expansion of the outer membrane part is limited by the walls 29, 30.
  • the outer wall 29 has a fastening edge 31 which engages in the circumferential groove 23 of the membrane holding ring 4.
  • the outer wall 31 is held between the outer surface of the annular projection 24 and an inner cylindrical surface 32 of the surrounding ring 3 and is thereby fixed in the radial direction.
  • the outer surface of the inner wall 30 of the membrane lies against a cylindrical surface 33 of the membrane retaining ring 4. It is pressed against this surface by the membrane holding plate 6. This holding plate is gripped by a fastening edge 33 which engages in a fold 34 of the membrane holding plate.
  • the feed A 1 works as follows.
  • the duct 15 is connected to a line through which air is drawn out and air with excess pressure can be supplied.
  • the room 1t is connected to another line through which compressed air can be supplied or air can be extracted.
  • the air supply or Air extraction via the duct 15 or the collecting space 5 are independent of one another.
  • a lens L 1 is inserted, there is ambient pressure on the underside of the membrane 5.
  • 5 certain pressures are built up below the membrane. In this case, different pressures can be built up under the middle part 25 and the outer part 26.
  • the pressure setting below the middle part 25 takes place via the channel 15, into which, depending on requirements, air with an overpressure relative to the environment is introduced or extracted via the air and a pressure is built up which is below the ambient pressure.
  • the channel 15 communicates via the recess 2a and a central bore 35 in the membrane holding plate 6 with the space 36 below the middle part of the membrane, which forms a first support zone. This space is sealed airtight in relation to the space 37 below the outer membrane part, namely by the sealing ring 9 and the membrane wall 30.
  • the space 37 communicates via the channels 21, the annular groove 20 and the channels 11 with the collecting space 12, so that a pressure can be built up via this flow path below the outer membrane part, which is independent of the pressure below the central membrane part 25. Der The outer membrane part 26 thus forms a second support zone. Pressure losses in this area are prevented from the outside by the sealing ring 10.
  • the lens L 1 is centered within the receiving chuck A 1 by the contact of its outer edge 38 on the cylindrical surface 32 of the surrounding ring 3.
  • the working pressure arises from the pressure of a processing tool, not shown in the drawing, which has the shape ner spherical cap and is pressed onto the lens surface 39.
  • a grinding paste is located between the processing tool and the lens surface 39.
  • the intake chuck A 2 according to FIG. 2 is used for the simultaneous processing of several lenses L 21, of which only one is shown in FIG. 2.
  • the receiving chuck A 2 has a base body 40, a support body 41, a surrounding ring 42 and a cap-like cover 43 which rests on the support body 41.
  • the base body 40 has a shaft 44 for holding the receiving chuck in a processing machine.
  • a central opening 45 for the penetration of a body 46 in which a channel 47 is located.
  • an annular groove for receiving an annular elastic seal 49, namely an O-ring.
  • the support body 41 lies with a flat lower surface 50 on the surface 48 of the base body and compresses the seal 49 elastically.
  • a channel 51 in the lower, internally threaded end of which the body 46 is screwed in such a way that its channel 47 communicates with the channel 51.
  • the support body 51 there are also a plurality of channels 52 which are inclined from the bottom inside to the top outside. The lower ends of the channels 52 open into the opening 45 of the base body 40. The upper end of each channel 52 opens into a cylindrical recess 53 of the support body 41. Via the support body 41, e.g. four depressions 53 may be distributed.
  • the support body 41 has an external groove 54 on the support body 41 for anchoring the cover 43.
  • the support body 41 has a fastening flange 55 below the groove 54, on which the support body 41 is pressed against the base body 40.
  • the surrounding ring 43 is used to connect the two bodies 40, 41. It has a shoulder 56 which presses on the flange 55. The surrounding ring is pressed onto a cylindrical outer surface 57 of the base body 40.
  • the cover 43 has a fastening edge 58 which engages in the outer groove 54 of the support body 41.
  • the mounting rim 58 is prevented from migrating out of the groove 54 by the encircling ring 42, which rests with a cylindrical surface 59 on a cylindrical surface 60 of the cover 43.
  • the cover 43 can be made of rubber, for example.
  • the coating 43 forms a membrane 61 in the region of each depression 53.
  • the membrane 61 forms with its upper side 62 the bottom of a depression for receiving a lens L 2 .
  • the depression is further delimited by a narrow cylindrical edge 63 which bears against the outer cylindrical edge 64 of the lens L 2 .
  • a cylindrical wall 66 protrudes from the rear side 65 of each membrane 61 and is integrally formed on the membrane and, over the membrane, on the covering 43.
  • the outside of the cylindrical wall 57 bears against the cylindrical wall of the depression 53.
  • a membrane holding plate 67 is arranged within the cylindrical wall 57 and has an off at its lower edge fold for the engagement of a retaining edge 68 which is located at the lower edge of the cylindrical wall 66. There is a central opening 69 in the membrane holding plate, which is aligned with the channel 52. The membrane holding plate is recessed at the top, so that a space 70 remains between the membrane 61 and the membrane holding body 67.
  • the circular membrane region 61a within the cylindrical wall 66 forms a first support zone.
  • the annular membrane region 61b outside the cylindrical wall 66 forms a second support zone.
  • a pressure can be built up under each support zone, which is independent of the pressure below the other support zone.
  • the pressurization of the first support zone 61a takes place via the opening 45 in the base body and the channels 52.
  • the pressurization of the support zones 61b takes place via the channel 51 be built up, but only up to the cylindrical walls 66, which prevent communication with the rooms 70.
  • the feed A 2 works as follows.
  • the channel 47 communicates with a line via which air can be supplied and removed.
  • the opening 45 communicates with a line via which air can also be supplied and removed. Air is supplied and removed via flow paths 47 and 45 via independent systems.
  • the channels 47, 51 are under a certain excess pressure, so that an air pressure which is greater than the ambient pressure builds up between the surface of the support body and the coating 43. As a result, the cylindrical edges of the lens receiving recesses are spread out, so that lenses could be inserted easily sen.
  • the pressure under the first support zones 61a is adjusted so that the working pressure of the tool cannot produce aspherical registration errors.
  • a pressure serving this purpose is also built up in the outer support zones 61b, which pressure is generally different from the pressure below the first support zones 61a.
  • the processing tool (not shown in the drawing) is a hollow spherical cap which covers the entire receiving chuck A 2 and whose spherical surface interacts simultaneously with all lenses L 2 ', for example four lenses L 2 .
