Definitions

  • the invention relates to a flange for mounting a tool, in particular grinding tool, such.
  • a tool in particular grinding tool, such.
  • the flange cooperates in the assembled state with one end with a spindle and in the region of the other opposite end has an orthogonal to the axis of rotation of the flange aligned receiving surface on which rests in the mounted state of the tool.
  • Tools in the form of grinding wheels are used in practice, for example, to edit the edges of objects, which consist of brittle materials, by grinding.
  • Such an article is, for example, a disk, such as a windshield of a motor vehicle.
  • the disadvantage is that when processing, for example, a disc in the tool vibrations can occur, which has a non-circular and restless running of the tool result.
  • a processing of the edge regions of objects, in particular of thicknesses of less than 3 mm is therefore no longer possible, since it is due to the Vibrations can lead to Ausplatzern in the edge region of the object to be machined.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a flange which allow the machining of thin, consisting of a brittle material objects, by a rotating tool, in particular a grinding wheel.
  • the flange for damping vibrations has at least a partial area which extends over the entire cross-sectional area of the flange and which consists of a vibration-damping material.
  • the flange may for example consist of metal, in particular of steel.
  • any resulting vibrations in the sub-area are reduced. Thus, neither vibrations are transmitted from the spindle to the tool nor vice versa transferred from the tool to the spindle.
  • a composite material has a higher natural frequency compared to steel, so that vibrations are correspondingly well degraded in the subregion.
  • the composite may consist of two or more bonded materials.
  • the connection of the materials with each other can be done by material or positive connection or a combination of both.
  • Particularly suitable are fiber composites, such as carbon fiber composites.
  • fiber composites small particles and / or fibers are embedded in a matrix, such as an epoxy matrix.
  • the fibers may extend in one or more particular directions. Fiber composites can also be produced in layers. In that regard, at least a portion of a plastic or a plastic composite material may be made.
  • At least one subarea can simultaneously form the receiving surface for the tool to be attached.
  • the portion at the same time represents the receiving surface of the flange.
  • the portion may be flanged either on a conventional flange.
  • a conventional flange is shortened in length before attaching the portion so that after attaching the portion of the flange has the same length as a conventional flange. Then the flange according to the invention can be used without structural changes in a conventional processing machine.
  • the flange may have two flange regions, between which at least one partial region is arranged.
  • the second flange region then adjoins this subarea, so that, viewed in the longitudinal direction of the flange, the two flange regions are separated from one another by the subregion.
  • the two flange portions form the two ends of the flange itself.
  • the flange according to the invention has the same length as a conventional flange. Then the flange according to the invention can be used without structural changes in a conventional processing machine.
  • the flange areas are made of steel, for example.
  • the subregion is constructive, i. for example, with respect to the thickness or other dimensions, formed so that the two flange portions do not touch.
  • At least one partial area and the adjacent flange or an adjacent flange area can be connected to one another by gluing.
  • each subregion is secured relative to the adjacent flange or an adjacent flange region by at least one pin, preferably aligned parallel to the axis of rotation of the flange.
  • the thickness d of the portion is chosen so that each pin protrudes with its one part length in the partial area and with its remaining part length only in the respective flange area.
  • a plurality of concentrically distributed over the circumference arranged pins are provided.
  • the subregion has a relation to the contact surface projecting, preferably cylindrically shaped and preferably concentric with the axis of rotation of the flange, centering, which in a corresponding recess of the flange or of the flange engages.
  • the flange or the flange region may have a centering projection projecting from the contact surface, preferably cylindrically shaped and preferably concentric with the axis of rotation of the flange, which engages in a corresponding recess of the partial region ,
  • the receiving surface has a relation to the receiving surface projecting, preferably cylindrically shaped and preferably concentric with the axis of rotation of the flange, centering, which in a corresponding tool-side recess engages.
  • the receiving surface has a relation to the receiving surface projecting, preferably cylindrically shaped and preferably concentric with the axis of rotation of the flange, centering, which in a corresponding tool-side recess engages.
  • At least one screw in particular as a center hole into which a screw is screwed, formed screw is provided.
  • the screw is arranged centrally.
  • Flange of two flange portions and a portion disposed therebetween, is useful when provided in the spindle-side flange portion and a thread in the workpiece-side flange portion and in the subregion formed as a through hole center hole for a screw.
  • a damping washer is provided between a clamping surface of the screw head oriented orthogonally to the rotational axis and a corresponding effective surface of the workpiece-side flange region.
  • the screw can be assigned a damping washer, through which the screw is performed.
  • the screw may be in the contact area on the underside of the screw head made of a damping material so far or provided with a damping material.
  • FIGURE shows a flange according to the invention, which consists in the illustrated embodiment of two end flange portions 1, 2 and a located between the two flange portions 1, 2 portion 3. Spaced to the flange, a tool 4 designed as a grinding wheel is shown.
  • the portion 3 extends over the entire cross-sectional area of the flange.
  • the portion 3 consists for example of a composite material, while the two flange portions 1, 2 are made for example of steel. Both Flange portions 1, 2 are separated from each other by the portion 3 seen in the longitudinal extent of the flange.
  • the left flange portion 1 shown in the figure is attached to a spindle 5.
  • the spindle 5 has a centrally conically converging receptacle 6 in the region of its free end. In this recording 6, the conically converging free end of the left flange portion 1 is introduced.
  • the flange region 1 has a contact surface 10.
  • a relative to the contact surface 10 projecting, cylindrically shaped and concentric with the axis of rotation 11 of the flange aligned centering projection 12 is provided, which engages in a corresponding recess 13 of the portion 3.
  • the portion 3 On its corresponding contact surface 14 on a projecting, cylindrically shaped and concentric with the axis of rotation 11 of the flange centering projection 15 which in a corresponding recess 16 of the right Flange portion 2 engages, which serves for tool holder.
  • the length of the pins 17 is selected so that the pin 17 protrudes with a partial length in the partial area 3 and with the remaining other partial length only in the respective flange 1 or 2.
  • a central bore 26 For axial securing a central bore 26 is provided, into which a screw 19 is screwed.
  • the middle bore 26 has a thread 27.
  • the central bore 26 is formed as a through hole.
  • the screw head 20 is countersunk in the right tool-side flange region 2.
  • a damping washer 21 is provided between the orthogonal to the rotation axis 11 aligned clamping surface of the screw head 20 and the corresponding effective surface of the flange portion 2.
  • the thickness d of the portion 3 can be set arbitrarily.
  • the thickness d is at least greater than the longest part length of a pin 17, which projects into the portion 3.
  • the tool 4 consists in the illustrated embodiment of a grinding wheel, which identifies a corresponding tool-side recess 22 for centering.
  • the tool-side recess 22 cooperates with a relative to a receiving surface 23 projecting, cylindrically shaped and concentrically aligned with the axis of rotation 11 of the flange centering 24 together.
