Definitions

  • the invention relates to a system for controlling the grinding wheel of a machine for grinding parts such as rails, comprising a wheel bearing device movable in a support frame between a position in which the grinding wheel is moved away from the workpiece and a position in which the grinding wheel is in contact with this part and a contact detection device of the grinding wheel with the part.
  • a control system of this type is known from the document EP 05 93 361, in its application to the grinding of railroad tracks, to redo the profile or to erase signs of wave or slip wear from wheels.
  • the main difficulty during such grinding comes from the rapid wear of the grinding wheel during job.
  • Known methods use principles for limiting the pressure of the grinding wheel on the rail or manual approaches, which does not guarantee sufficient precision and does not authorize a integration into this automatic process.
  • the object of the present invention is to provide a device capable of accurately detecting docking of the grinding wheel on the rail and this whatever the conditions of use and the environment.
  • control system is characterized in that the means of detection of the contact between the grinding wheel and the workpiece is a device for detecting sparks produced during of this contact.
  • the detection device includes a sensor for sparks placed near the grinding wheel, a detector of light, which is offset and arranged in a location protected against parasites, and a means of transmission of light between the sensor and the detector.
  • the transmission means are formed by an optical fiber.
  • the machine essentially comprises a grinding wheel 1 placed on a grinding wheel carriage 2 movable along a beam 3 which is pivotally mounted at each of its ends on a displacement device 4 in translation of the beam 3.
  • This drive device in translation 4 of the beam is mounted on a module 5 of rotation of the beam around the rail 6.
  • This set is mounted on a support frame 7 which has two elements 8, 9 each in the form of a frame through which extends the rail 6. The two frame elements are placed at a certain distance from each other, in the longitudinal direction of the rail 6.
  • the grinding wheel 1 is rotatably mounted on the carriage 2 and is rotated by a hydraulic motor 11.
  • the translational drive device 4 of the beam 3 essentially comprises a driving element 12 such as a jack provided with a rod 13 at the end of which the end of beam 3 is articulated.
  • grinding also comprises a device for retaining the rail 6, which essentially comprises stop members 15 as well as at the level of each frame 8, 9 a rail clamping cylinder 17 and a clamping cylinder rails 18, which act perpendicular to the direction longitudinal of the rail to push it on the stop elements 19.
  • the grinding wheel carriage 2 door above the grinding wheel 1 a protective plate 20, advantageously made of aluminum, which extends perpendicular to the axis of the grinding wheel while styling it.
  • a sensor 22 which allows recognition of the emission of sparks produced when the grinding wheel 1 comes into contact with the workpiece, in the example shown rail 6.
  • This sensor essentially comprises a block 21, advantageously made of aluminum, and a sensor member made of shape of a plexiglass pad 23, mounted in the block 21 at the narrower bottom of a conical channel 25 opening towards grinding wheel 1 and tangentially arranged compared to the latter.
  • the opening 26 of the channel is located at a certain distance from the contact point of the grinding wheel with the rail.
  • the pellet is housed in a support 28 coming to screw in abutment on the end of an optical fiber 29.
  • the fiber is held in the block by a tightening screw 30
  • a blowing device of air is integrated into the block and has conduits 31 which open in channel 25 and through which air tablet is blown into the canal to prevent dust and grinding particles can enter in the canal and reach the plexiglass patch at bottom of the canal.
  • the other end of the optical fiber 29 is connected to a light detector 33 formed advantageously by a photodiode and mounted together with its electronics, in a sealed waterproof box 34 on the grinding wheel carriage 2, as seen on the Figure 2.
  • the housing 34 is offset from the sensor of sparks 22 and located at a location where it is protected against thermal variations, vibrations, grinding particles and dust.
  • the housing is cooled to prevent degradation of components it contains. As seen in Figure 2, the housing is located at the top of the carriage 2, above the protective plate 20.
  • the wheel is slightly tilted at an angle inclination of 1 or 2 ° from the rails, on the rear of its longitudinal displacement movement. So the grindstone front is biting and you get a quasi-punctual contact of the grinding wheel with the rail. The location of production of sparks during the docking of the wheel on the rail is therefore well defined.
  • the invention has many advantages by state of the art. By proposing a process optical detection of the wheel coming into contact with the rail, by recognition of the emission of sparks, in taking into account in particular the frequency of light emitted as a function of the temperature of the loose grains and heated by friction, the invention is not subject to noise propagating in the rail.
  • the offset light detection means and controls, light capture point by optical fibers provides perfect protection against variations thermal, vibration, dust and noise. Protection against light interference is ensured by the use of an infrared wavelength and an angle of capture of the end of the optical fiber. Protection against electrical noise is obtained by the arrangement in a compact block of the detector and electronic processing unit.
