  • the advantages of this non-contact Measuring device of the invention are: Less wear of the Dimensional transmission, as the rail no longer touched touching is, and thus no wear on the measuring pin arises. Errors due to dimensional translations (gears, analog-to-digital converters etc.) are avoided. At the same time increases the standby time of the meter. Higher accuracy the measurement because the individual parameters without the above measured wear, systematically avoided errors and the repeatability can be improved enormously.

  • Laser 1 is in a recording 9 mounted, with which one the laser beam in can move all three axes.
  • the laser beam has to be exact to 14 mm below rail level at a vertical angle hit the rail axis. Does the laser beam have one Angle deviation, the laser point moves, depending on the angle error, with track adjustment along the rail contour along and can no longer be accurately detected by the CCD unit 4 become.
  • Fig. 4 Opposite rail 2 is for improved detection a Radlenker 3 set with the smallest assuming distance. Between rail 2 and 3 Radlenker is a cross slide 7 mounted for movements in x and y direction. On the cross slide 7 is the recording for a mirror 10. With this recording it is additional possible to turn the mirror 10 about its own axis and to adjust in height.
  • the laser 1 is parallel to Rail 2 mounted (in Fig. 4 rotated by 90 °, for the better Representation), so that its beam is on the mirror axis meets.
  • the laser beam is transmitted through the mirror 10 to the Driving edge or projected onto the Radscher 3 and from the CCD unit 4 detected when it is exactly 14 mm below rail top and impinges at 90 ° to the rail axis.

  • the laser distance sensor 6 operates according to the triangulation principle with a certain distance to the workpiece 2, 3, in which its measuring range begins. On Due to its size, the laser distance sensor 1 can not directly the distance between itself and the workpiece 2, 3 measure up. It must also here the laser beam over a Mirror mechanism on the rail 2 or Radlenker 3 projected In FIG. 5, the laser distance sensor is rotated by 90 °, for a clearer presentation). Sensor 6 and mirror 10 are rigidly connected and thus are here Angle error rather avoid, as with the CCD unit. 4 Compared to vibration, this system is less sensitive, as in the CCD unit 4 of FIG. 4th
  • a miniature sensor 6 measures the distance to the rail 2 and the other sensor 6 measures the distance to Radlenker 3. These measured data are offset against each other and a real result is determined from this.
