Definitions

  • the invention is related to grinding wheel and carrier flange configuration on which the grinding wheels are connected in double wheel face grinding machines.
  • cooling fluid can be fed continuously and at constant flow rate to the workpiece that is being ground between the two wheels.
  • the cooling fluid being fed through the hole in the center of the wheel carrying flange cools the workpiece by spreading over the grinding wheel surface through the grooves cut on the surface of the grinding wheel that grinds the workpiece.
  • the depth of the grooves diminishes due to removed surface material and therefore the amount of flowing cooling fluid decreases.
  • the workpiece is not cooled sufficiently, grinding burns occur on the ground surfaces and the workpiece becomes unusable.
  • the wheels need to be removed and new grooves should be cut. This method both causes waste of time and creates risks in terms of work safety.
  • the depth of the grooves on the grinding wheel diminish as the grinding wheel is sharpened, thus the flow rate of the cooling fluid gradually decreases.
  • the cooling fluid is conveyed to each groove of the grinding wheel through a single hole.
  • the cooling fluid is conveyed to the through grooves machined on the grinding wheel via the grooves machined on the carrier grinding wheel.
  • the systems that feed cooling fluid to cool the workpiece via the grinding wheel differ from the grinding wheel and carrier flange configuration described in this document by feeding of cooling fluid into the through grooves machined on the grinding wheel via the grooves machined on the carrier grinding wheel.
  • the object of this invention is to realize the grinding wheel and carrier flange configuration that enables constant flow and continuous feeding of cooling fluid into the through grooves machined on the grinding wheel via the grooves machined on the carrier grinding wheel.
  • Figure-l is a general schematic view of the grinding wheel and carrier flange configuration of the invention.
  • Figure-2 is a schematic view of the channels and the grooves in the grinding wheel and carrier flange configuration of the invention.
  • Figure-3 is another schematic view of the channels in the grinding wheel and carrier flange configuration of the invention.
  • Figure-4 is a schematic view of the channels and the nut in the grinding wheel and carrier flange configuration of the invention.
  • the grinding wheel (1) and carrier flange (2) configuration of the invention comprises;
  • the grinding wheel (1) that grinds the workpiece (8) and that enables passage of cooling fluid through the channels (9) machined along the thickness of the grinding wheel (1),
  • the bolt (5) that attaches the grinding wheel (1) to the carrier flange (2)
  • the circular groove (6) that accumulates the cooling water coming from the grinding machine and that transfers it to the groove (7) on the other side of the carrier flange (2) through the hole on the carrier flange (2)
  • the groove (7) which is the space machined inside the carrier flange (2) and that accumulates the cooling fluid coming from the carrier flange (2) body and that transmits it to the corresponding channels (9) on the grinding wheel (1),
  • the workpiece (8) which is located between the upper guideway (3) and the lower guideway (4), on which continuous cooling fluid at constant flow rate is fed while it is being ground by the grinding wheel (1) and thus the grinding burns are prevented,
  • the channel (9) which is in the form of holes cut in the grinding wheel (1) and that conveys the cooling fluid passing through to the workpiece (8).
  • the grinding wheel (1) enables feeding of cooling fluid to the workpiece (8) through the channels (9) machined along the thickness of the grinding wheel (1) during grinding of the workpiece (8) and prevents workpiece (8) burns.
  • the cooling fluid that accumulates in the circular groove (6) passes through the hole in the center of the carrier flange (2), then to the grooves (7) on the connection surface of the carrier flange (2) with the grinding wheel (1), from the grooves (7) to the channels (9) machined along the thickness of the grinding wheel (1) and finally from the channels (9) to the workpiece (8).
  • the cooling fluid enables cooling by flowing continuously and at constant flow rate and prevents grinding burns.
  • the grinding wheel (1) and carrier flange (2) configuration (2) of the invention differs from the known state of the art in that there is no groove on the grinding wheel (1) and but instead there are channels (9) machined along the thickness of the grinding wheel on the wheel. Moreover, there are the circular groove (6) and the groove (7) in the front and back of the grinding wheel that serve as the balancing factor of the cooling fluid flow rate. Besides these channels (9), there are bolts (5) embedded into the grinding wheel (1) in order to attach the grinding wheel (1) to the carrier flange (2).
  • Grooves (7) are machined on the surface of the carrier flange (2) to which the grinding wheel (1) is connected such that they correspond to the channels (9) machined on the grinding wheel (1).
  • the grinding wheel (1) is connected to the carrier flange (2) by the bolts (5).
  • the cooling fluid that comes from the part of the grinding wheel carrier flange (2) that is connected to the grinding machine and that is accumulated in the circular groove (6) machined on it, passes through the hole in the center of the carrier flange (2), then to the grooves (7) on the connection surface of the carrier flange (2) with the grinding wheel (1), then to the channels (9) machined along the thickness of the grinding wheel (1) and finally to the workpiece (8).
  • This continuous and constant flow feeding of the cooling fluid enables cooling and prevents grinding burns.

Abstract

L'invention concerne une configuration de roues de meulage (1) et de bride de support (2), sur laquelle configuration les roues de meulage (1) sont reliées dans des machines de meulage de face à doubles roues. Par la configuration de roues de meulage (1) et de bride de support (2) selon l'invention, un fluide de refroidissement peut être acheminé de façon continue et sous un débit d'écoulement constant jusqu'à la pièce à travailler (8) qui est meulée entre les deux roues pendant l'opération de meulage. La roue de meulage (1) qui meule la pièce à travailler (8) permet l'alimentation d'un fluide de refroidissement à travers les canaux (9) usinés le long de l'épaisseur de la roue de meulage (1). La bride de support (2) sur laquelle la roue de meulage (1) est attachée par le boulon (5) permet l'alimentation de fluide de refroidissement aux canaux (9) par l'intermédiaire de la rainure circulaire (6) et de la rainure (7) sur elle-même.
