Definitions

  • the invention relates to a copying device for dressing grinding wheels, in particular profiled grinding wheels, according to the preamble of claim 1.
  • the copying finger in the form of a probe head is moved along a guide profile of the dressing template. These movements are transferred to the dressing tool, which is then used to machine the grinding wheel in accordance with the scanned guide profile. Moving the guide profile requires great experience to dress the grinding wheel exactly according to the guide profile.
  • the dressing tool must be precisely guided and adjusted in relation to the grinding wheel in order to obtain the desired profile on it.
  • the invention has for its object the genus moderate copying device so that the grinding wheels can be dressed quickly and precisely without additional work in the grinding machine.
  • the copying device has two dressing tools which take effect one after the other in the dressing process.
  • the profile of the dressing template to be scanned corresponds to the profile of the dressing device with the two dressing tools.
  • the dressing template can be moved along the copying finger easily and with less experienced forces during the dressing process. Since the two dressing tools can be adjusted relative to one another, it is easily possible to adjust the dressing tools when worn so that the grinding wheel to be dressed is given the desired profile.
  • the drawing shows a dressing device according to the invention for grinding wheels in a schematic representation.
  • the dressing device 1 which is shown in the drawing for the sake of simplicity in front and side view, has a holder 2, which is preferred on a carrier 3 is releasably attached.
  • the carrier 3 connects the dressing device 1 to a copying device 4. It has a dressing template 5 detachably attached to the carrier 1 and a copying finger 6. It is in turn exchangeably fastened to a holder 7.
  • the holder 2 has two arms 8 and 9 which project transversely from it and each carry a dressing tool 10, 11.
  • the two arms 8, 9 are held together by a tension element 12, preferably a screw. With this tension element 12, the two arms 8, 9 and thus the dressing tools 10, 11 can be set in an exact mutual position.
  • a pressure piece 13 is also accommodated, which is preferably designed as a stud. In the exemplary embodiment, it is screwed into the arm 9 and is supported on the arm 8 with its free end.
  • the tension element 12 and the pressure piece 13 are each sunk in the arms, so that there is no risk of damage when working with the dressing device 1.
  • the dressing tools 10 and 11 are designed as rollers, the jacket of which is covered with an abrasion material, preferably diamond.
  • the lateral surfaces 14, 15 of the two dressing tools 10, 11 are spherical in cross section.
  • the dressing tools 10, 11 are detachably attached to the free ends of the arms 8 and 9. They are arranged in such a way that the dressing tools 10, 11, with their sides facing away from one another, protrude beyond the outer sides 16 and 17 of the arms 8, 9 facing away from one another and also over the end face 18, 19 thereof.
  • the dressing template 5 has the copying finger 6 on it facing area the same outline as the two arms 8, 9 with the dressing tools 10, 11th
  • the grinding wheel 20 to be dressed has a jacket 21 which is semicircular in axial section.
  • the copying finger 6 now has a diameter d which is precisely matched to the radius of the jacket surface 21 of the grinding wheel 20.
  • the dressing template 5 and the dressing device 1 are arranged in exactly the same way with respect to their described outline shape and also with regard to their radial position with respect to the carrier 3.
  • the grinding wheel 20 and the copying finger 6 are arranged such that the dressing tool 11 comes into contact with the side surface 22 of the grinding wheel 20 when the dressing template 5 comes into contact with the copying finger 6 with its side surface 23 facing the dressing device 1.
  • the dressing template 5 is now guided along the edge of the copying finger 6. Since the dressing template 5 is connected to the dressing device 1 via the carrier 3, the dressing device describes the same path as the dressing template 5.
  • the grinding wheel 20 is profiled exactly to the shape of the copying finger 6.
  • the radius or diameter d of the copying finger 6 specifies the curvature of the outer surface 21 of the grinding wheel 20.
  • the dressing tool 11 is first brought up to the side surface 22 of the grinding wheel 20 and then moved downward.
  • the side surface 22 of the grinding wheel is dressed.
  • the dressing tool 11 then reaches the lateral surface 21 and trims it up to half the thickness of the grinding wheel 20.
  • the dressing tool 11 comes out Engagement with the grinding wheel jacket.
  • the dressing template 5 lies against the copying finger 6 with its straight end face 24.
  • the dressing tool 10 comes to rest against the lateral surface 21 in half the width of the grinding wheel 10 and then profiles the remaining part of the grinding wheel lateral surface until it reaches the other side surface 25 of the grinding wheel 20.
  • This side surface 25 can then also be dressed with the dressing tool 10.
  • the dressing template 5 is guided with its side surface 26 along the copying finger 6.
  • the dressing rollers 10 and 11 are exposed to wear, so that after a long period of use the grinding wheel profile no longer corresponds to the target grinding wheel profile. This can be determined, for example, simply by measuring the dressed grinding wheel thickness and comparing it with the diameter d of the copying finger 6. If there are dimensional deviations, this is an indication of the wear of the dressing unit witnesses 10 and 11. Since they are provided on the elastically bendable arms 8 and 9, it is easily possible to exactly compensate for this wear by adjusting the dressing tools.
  • the tension element 12 is only necessary to release the tension element 12 and then elastically spread the two arms 8 and 9 apart with the pressure piece 13. Since the pressure piece 13 is a screw, the desired distance between the two dressing tools 10 and 11 can be continuously adjusted by screwing in. As soon as the desired distance is set, the tension screw 12 is screwed back again and the two arms 8 and 9 are firmly connected to one another again in the newly set position.
  • two arms 8 and 9 which are completely separate from one another can also be provided for the dressing tools 10 and 11.
  • the arms 8 and 9 are moved against each other, for example. This also ensures exact readjustment.
  • the dressing device 1 is fixedly mounted in the grinding machine (not shown) and adjusted to the distance between the center of the grinding wheel 20 and the center of the respective copying finger 6. The distance between the dressing device 1 and the dressing template 5 is also set accordingly.
  • the dressing tools 10, 11 can also have a square or semicircular cross section, for example.
  • other suitable materials such as nonwovens, are also suitable as materials for dressing.
