Definitions

  • the invention relates to a grinding machine with a rotating device for receiving a roller to be ground with a slight deviation from the cylindrical shape, containing profile, with a measuring arm, one end of which is connected to the support of the grindstone and at the other end one towards the Axis of the rotating device is movably arranged holder, which contains a component for maintaining a constant distance from the surface of the roller and is attached to the holder, the probe of a measuring or testing device for monitoring and regulating the manually controlled grinding process.
  • a grinding machine is known in which a lightly grinding stylus and an air nozzle are used to measure the diameter of the roller.
  • the stylus also wears out in this construction.
  • the air nozzle and its downstream regulators cause a constant distance between the air nozzle and the roller only when the desired state of the roller has been reached by grinding. The distances are different before sanding. For these reasons, the principle is not suitable for determining extremely precise changes in diameter and no further measuring probes can be attached to the air nozzle, the function of which presupposes compliance with a precise distance from the roller.
  • the component for maintaining a constant distance from the surface of the roller does not come into contact with it and consists of a known contact-free measuring part in the form of an air nozzle which with a holder to or from the Roller moving piston is connected by a channel so that changes in dynamic pressure cause movement of the
  • Effect piston in the direction of restoring the desired distance and more than one probe of test or measuring devices are attached to the holder, which are in the test or measuring state with a grinding grindstone and rotating rotating device.
  • the change in diameter of the roller can be determined particularly precisely and easily if a length measuring device is installed between the measuring arm and the holder. Every change in the diameter of the roller leads to an adjustment movement of the holder, as a result of which the holder changes its position or distance from the measuring arm. These changes are proportional to the change in diameter. Any length measuring device can be used.
  • the relatively complex device for precise spacing of the bracket is used twice or more if the bracket additionally z.
  • the device for measuring the diameter changes is also used several times if it is also used for the precise alignment of the roller in the turning device.
  • the alignment device of the bearings of the rotating device is connected to the length measuring device on the measuring arm via a memory and comparator.
  • the grinding machine advantageously contains a pre-programmable automatic control for the movement of the grindstone perpendicular to the axis of the rotating device and for the movement of the support parallel to the axis of the rotating device, which are connected via a comparator to the length measuring device on the measuring arm.
  • the grinding machine 11 can be moved with the grinding stone 12 on the support 13 parallel to the axis of rotation 14 of the rotating device 15. In addition, the grinding machine 11 can still be moved in the direction perpendicular to the axis of rotation 14.
  • the measuring arm 16 is fastened to the grinding machine 11, on which in turn a holder 17 is fastened via an adjusting device 18.
  • the air nozzle 19 and a probe 20 for crack testing are located under the holder 17.
  • the grindstone 12 is moved against the roller 21 to be ground and grinds it while the roller 21 is rotated by the rotary drive 15.
  • a length measuring device installed in the housing of the adjusting device 18 continuously measures the changes in diameter of the roller 21 in the area just ground.
  • the adjustment device 18 holds the holder 17 at a uniform distance from the surface of the roller 21, so that the air nozzle 19 on the holder 17 is at a distance of approximately 0.2 mm from the surface of the roller 21.
  • the roller 21 is deliberately ground somewhat spherically, as is required in rolling mills for the production of sheet steel.
  • the crown is in the fir. 2 shown.
  • the measurement results of the changes in diameter can also be shown as a curve on a screen over the length of the roller, as shown in FIG. 3. The operator can see the grinding processes still required from the comparison with the target curve and the actual curve.
  • the bearings 26 and 27 of the steady rests are adjustable by drives, not shown. These drives are automatically controlled by the measuring devices 22 to 25.
  • the measuring devices 22 to 25 are constructed on the same principle as the already operated air nozzle 19 and adjusting device 18.
  • the measuring devices 22 and 23 can be saved if the measuring arm 16 is moved along the roller 21 for the purpose of measurement and the measurement results at the edge of the end face of the roller 21 are compared.
  • the measurement of the absolute diameter of the roller to be ground is possible if two measuring probes opposite each other on the roller are attached to a common measuring bracket.
  • the determination of the absolute diameter is z. B. important for the pair of grinding of the rollers, since the same peripheral speeds must be present in the roll stand. These are only available if the rollers have exactly the same diameter.
  • the grinding machine can not only grind symmetrical profiles, according to FIG. 2. There are also z. B. pear-shaped profiles, corresponding to FIG. 5, possible.
