Definitions

  • the invention relates to an eyeglass lens grinding machine with a grinding wheel driven by a motor.
  • the grinding wheel and the template counter bearing are mounted in a stationary manner in the machine frame, the grinding wheel being driven by a motor arranged in this frame.
  • the eyeglass lens and the template holding or rotating the eyeglass holder shaft is pivotable about a horizontal axis in an upper part rotatable about a vertical axis in such a way that the eyeglass lie on the grinding wheel and the template lie on their counter bearing using gravity horizontal pivoting of the eyeglass lens about the vertical axis of the machine upper part and further by the up and down pivoting of the part supporting the lens holder shaft un the horizontal axis on the machine upper part, there are two circular arc sections which are perpendicular or approximately perpendicular to one another and on which the spectacle lens moves.
  • the object of the invention is to facilitate the relative adjustment or movement of the spectacle lens relative to the grinding wheel and to make the path of one of the two parts more precise compared to the other part, i. H. to be able to determine both the relative pressure of the spectacle lens against the grinding wheel better than hitherto; B. in an electronic or electrical control of the movement of one of the two parts, this movement can be mastered without problems.
  • the machine should be designed to be structurally simple.
  • the invention provides a spectacle lens edge grinding machine of the type mentioned, which is characterized in that the motor and the grinding wheel can be adjusted in the horizontal plane in two mutually perpendicular directions relative to the stationary spectacle lens.
  • the motor and the grinding wheel are arranged on a common carriage which is directed towards the eyeglass lens and
  • the triangular positioning of the carriage on the movable plate has the great advantage that the horizontal guide rod on the plate alone searches for a precisely defined guide for the carriage, while the roller or joint bearing at the top of the bearing triangle has one in relation to the guidance of the slide does not form a forced guidance.
  • This type of guide is in contrast to known guides on two parallel guide rods, the storage of which must be very precise in order to allow the carriage to be moved very easily in the longitudinal direction of the two guide rods.
  • the blade processing the lens 1 on its edge is driven by a motor 4 via a belt drive 3.
  • a particularly preferred embodiment which allows the motor and the grinding wheel to move freely in a straight line parallel to the grinding wheel axis when the spectacle lens for the facet grinder lies in the groove of the grinding wheel, provides that the slide on the plate eliminates a three-way bearing. This consists of a horizontal guide rod on the plate near the grinding wheel and a ball or roller bearing near the motor at the top of the bearing triangle.
  • the spectacle lens edge grinding machine has the advantage that, due to the linear movement of the grinding wheel relative to the spectacle lens, the two parts mentioned no longer perform an arc-shaped movement, thereby making facet grinding easier and more precise. If the grinding process is subject to electronic or electrical control, the straight-line movement of the grinding wheel relative to the prilled glass is of particular advantage.
  • the motor or spring force to adjust the on the slide is also straightforward of the slide and the motor as well as the grinding wheel can be controlled more precisely than if the parts were one .
  • Template is arranged, is fixed in the machine frame and rotated in a known manner by one of the two half-shafts by a motor.
  • the grinding wheel shaft 6, which is driven by the motor 4 via the belt 3, is directed parallel to the shaft 5 of the spectacle lens and the template.
  • the shaft of the motor 7 is also parallel to the shaft 5.
  • Both the grinding wheel 2, which consists of the section 8 for circumferential grinding and the section 9 with the facet groove 10, and the motor 4 are mounted on a carriage 11.
  • it has two angular supports 12, between the vertical legs 13 of which the grinding wheel shaft 6 extends, the indices of which are held in bearing bores 14, 15 and on which the grinding wheel 2 is arranged in a rotationally fixed manner approximately in the middle of the shaft.
  • the horizontal leg 16, 17 of each carrier 12, which engages the strikers 11, is connected to the carriage 11 and each provided with a bore 18 through which the ends of a guide rod 19 protrude.
  • This rod is held in a block 20 which is shorter than the distance between the legs 16, 17 from one another, the two angular supports 12 being freely displaceable on the rod ends 19 or else these ends are connected to the supports 12 and the block 12 between them Carriers can move freely.
  • the block 20 sits parallel to the grinding wheel shaft 6 a plate 21 which carries a guide block 24, 25 in the vicinity of its two edges 22, 23, which is located at right angles to the grinding wheel shaft 6 and through which a further guide rod 26, 27 projects in the longitudinal direction, the ends of which are fixed in place on the machine frame arranged support blocks 28 are held.
  • the plate 21 carries near its edge 29 a pin holder 30 with a perpendicular to the longitudinal axis of the guide rod 19 bearing pin 31 for a ball or roller bearing roller 32 on which the underside 33 of the carriage 11 is supported.
  • a pin holder 30 with a perpendicular to the longitudinal axis of the guide rod 19 bearing pin 31 for a ball or roller bearing roller 32 on which the underside 33 of the carriage 11 is supported.
  • the carriage 11 is thus guided at the ends of the rod 19 and lies there on the rod, while the section of the carriage 11 located below the motor 4 falls onto the roller 32.
  • a triangular bearing is realized, which is symbolized by the two lines 34, 35 and the guide rod 19.
  • the preferably spherical roller 32 is not a guide for the carriage 11, but rather only a rolling support.
  • the adjusting means engages for the movement of the carriage in the direction of arrow S on the plate 21.
  • a pulling device in the form of a band, a mette or the like. 36 can be used, which can be opposite a spring 37 at the other end of the plate 21, which is fixed at 36 to the machine frame.
