Definitions

  • the present invention relates to a grinding wheel dressing unit having a dresser shaft, a dressing roller and a dressing roller mounting device for mounting the dressing roller on the dresser shaft of the grinding wheel dressing unit.
  • Grinding wheel dressing units are used for profiling grinding wheels and are often integrated directly into grinding machines. They have their own drive unit for driving a dresser shaft on which the dressing roller is mounted. By sinking the rotating dressing roller into the rotating grinding wheel, a dressing of the grinding wheel profile takes place.
  • the dressing can be done intermittently or continuously during the processing of a workpiece by the grinding wheel, wherein continuous dressing is advantageous in that clogging of the grinding wheel with metal particles is prevented and thus a constantly sharp grinding wheel is guaranteed.
  • the grinding wheel diameter reduction caused by the grinding wheel wear during machining and by the dressing process is compensated by means of a corresponding feed of the dressing roller.
  • the DE-A-35 31 044 discloses a tool and method for profiling and dressing a grinding wheel.
  • Yet another object is to provide a Abrichtrollenmontage founded in which can be dispensed with expensive installation tools, in particular on heat cabinets and refrigerators.
  • a Schleifscheibnabrichtech of the aforementioned type which is characterized in that the Abrichtrollenmontage dressed has a positionable at a free end of the dresser shaft mounting sleeve, the outer surface is provided with a conical mounting portion serving as centering and Aufschiebe ashamed during assembly of the dressing roller on the dresser shaft, wherein a maximum outside diameter of the conical mounting area is smaller than or equal to a dressing roller receiving diameter of the dresser shaft.
  • the dressing roll bore is not slid directly onto the end of the dresser shaft, but first onto the conical mounting region of the dressing roll assembly, the diameter of which is less than or equal to the dressing roll take-up diameter of the dresser shaft.
  • a tilting of the dressing roller of the dresser shaft when placing the dressing roller on the dresser shaft and, accordingly, damage of the highly precisely manufactured Hole or shaft can be safely prevented.
  • a mounting or dismounting of the dresser shaft can also take place relatively easily in the processing space of a grinding machine.
  • the automatic centering of the dressing roll bore to the dresser shaft when pushed onto the conical mounting region of the dressing roll mounting device according to the invention and the associated optimized alignment of the components to be joined make the use of heat and / or cold cabinets superfluous. Accordingly, assembly / disassembly times and costs can be reduced.
  • the outer surface of the mounting sleeve may be provided with a conical disassembly area, which serves as Abstreifhne during disassembly of the dressing roller from the dresser shaft. In this way, the disassembly is much easier.
  • the mounting area and the disassembly area are advantageously arranged such that they merge into one another.
  • the dismantling area is preferably in the intended condition of Abrichtrollenmontage issued facing the dresser shaft, while the mounting region of the dresser shaft is facing away.
  • the mounting area and, if present, the disassembly area preferably extend over the entire length of the mounting sleeve, so that it is used optimally.
  • the mounting sleeve is preferably designed such that it can be fastened to a spindle journal of the dresser shaft.
  • the Abrichtrollenmontage appeared particularly easy to mount on the dresser shaft.
  • the mounting sleeve is preferably made of a material having a high hardness, such as, for example, an advantageously hardened chromium-nickel alloy.
  • FIG. 1 shows a Abrichtrollenmontage worn 10 during installation of a dressing roller 12 on a dresser shaft 14 of a grinding wheel dressing unit, not shown.
  • the Abrichtrollenmontage stimulating 10 consists of an elongate mounting sleeve 16 which is centrally provided with a through hole 18. In the in FIG. 1 illustrated state, this mounting sleeve 16 is attached to the spindle pin 20 of the dresser 14, which is received during normal operation of the grinding machine dressing in a corresponding storage.
  • the outer surface of the mounting sleeve 16 along its entire length L is provided with a conical mounting portion 22 whose outer diameter, starting from a maximum outer diameter d max in the direction of the free end 23 of the spindle pin 20 is tapered to a minimum outside diameter d min , where d max ⁇ the dressing roll take-up diameter D.
  • the mounting sleeve 16 can be withdrawn from the spindle pin 20 so that the spindle pin 20 can be re-stored (not shown).
  • the dressing roller 12 is still secured with corresponding fastening elements (not shown), one of which is screwed onto the external thread 27 of the dresser shaft 14.
  • the mounting sleeve 16 is again positioned on the spindle pin 20 of the dresser shaft 14, so that the dressing roller 12 can be deducted guided by the mounting sleeve 16 of the dresser shaft 14. Again, damage to the Abrichtrollenbohrung 25 of the dresser shaft 14 is prevented thanks to the guide through the mounting sleeve 16.
  • FIG. 2 shows an arrangement similar to FIG. 1
  • an alternative dressing roll mounting device 30 according to a second embodiment of the present invention is provided.
  • the Abrichtrollenmontage founded 30 is in the form of an elongated mounting sleeve 32 made of a hardened chromium-nickel alloy provided through which extends centrally a through hole 34.
  • the mounting sleeve 16 and the mounting sleeve 32 is attached to a spindle pin 20 of the dresser 14.
  • the outer surface of the mounting sleeve 32 is provided with a conical mounting portion 36 extending from a free end of the assembled mounting sleeve 32 over about 3 ⁇ 4 of the length L of the mounting sleeve 32 and gradually widens up to a maximum outer diameter d max where d max ⁇ the dressing roll take-up diameter D.
  • a disassembly area 38 whose outer diameter tapers again until the end of the mounting sleeve 32, adjoins the mounting area 36 without transition.
  • the mounting portion 36 of the mounting sleeve 32 unfolds substantially the same effect as the mounting portion 22 of the mounting sleeve 16 of FIG FIG. 1 shown Abrichtrollenmontage liked 10, which is why will not be discussed again.
  • the disassembly portion 38 of the mounting sleeve 16 facilitates the removal of the dressing roller 12 from the dresser shaft 14 during disassembly.
