Definitions

  • the invention relates to a spectacle lens edge grinding machine, in particular a hand grinding machine, with a grinding wheel and a motor driving it.
  • the spectacle lens and the coaxial template are held on the machine upper part, while the grinding wheel is driven in the base frame by a belt drive.
  • the spectacle lens and the template can be held on a bracket mounted in the machine frame, while the grinding wheel with its motor and the transmission means are preferably moved in a straight line on a slide.
  • the grinding wheel with its location is in the base frame stored and driven via a belt drive by a motor in the frame or placed directly on one end of the motor shaft.
  • the object of the invention is to create a structurally simple and inexpensive machine which is space-saving and maintenance-friendly, exhibits favorable behavior during operation and can also be used to carry out additional, preferably manual, grinding operations.
  • the invention provides a spectacle lens edge grinding machine of the type mentioned at the outset, in which the motor is an external rotor motor and the grinding wheel is arranged directly on the rotating rotor or rotor.
  • external rotor motors are used as asynchronous motors with an internal chain part and a rotor or a rotor for driving sound recording and reproducing devices.
  • the rotor or rotor is provided with a pulley, via which the rotary movement is then transmitted to a further part of the device, the advantage of the external rotor motor, namely a large momentum and small speed fluctuations for sound recording and Playback devices are used.
  • the specialist for spectacle lens edge grinding machines had no reference to the idea of the invention to put the grinding wheel and thus the working part of the machine directly on the rotor or rotor.
  • the advantage of the machine according to the invention is that a transmission means such as belts or the like can be dispensed with and the machine is therefore maintenance-friendly and structurally simple. Since the rotor or rotor is integrated directly into the scope of the motor, the entire lens edge grinding machine is very narrow and extremely space-saving. It has a favorable symmetrical arrangement of its rotating head and its ice speed is excellent in grinding. In the free areas can "In the drawing, an embodiment of the invention is shown in side view.
  • the base frame 1 of the machine has a mounting bracket 2, the horizontal web 3 of which is connected to the frame, while the vertical, longer web 4 carries the motor.
  • the motor flange 5 is connected via screw means 6 to the vertical web 4 of the angle 8, so that the motor is arranged on the fly.
  • a two-sided mounting of the motor can also be selected.
  • the asynchronous external rotor motor has the external rotor or rotor 7 with short-circuit winding and the stator C with the power supply unit, which is penetrated by the rotor or rotor shaft 9, which protrudes from the stator on both sides of the motor.
  • the shaft end 10 is guided through a bore 11 of the vertical web 4 of the angle 2.
  • the grinding wheel 13 has a further recess 17 into which a ring 18 is fitted, which holds the grinding wheel while resting on the flange 12 by means of the screws 19 distributed evenly.
  • the concentricity of the rotor or rotor and the grinding wheel can be achieved by suitable means.
  • the shaft end 10 carries a conical machining tool 20, while the end 21 of the shaft 9 is provided with a coupling device 21, with the aid of which another, preferably a flexible shaft, is connected to the shaft 9 of the rotor or rotor 7 - can be.
  • the gap is to keep grinding fluid away from the stator and the short-circuit winding of the rotor or rotor sealed between stator and rotor or rotor in a manner not shown with known means.
  • the external rotor motor accommodates the grinding wheel with its drive in the smallest space and the motor itself offers the possibility of connecting further tools.
