Definitions

  • the invention relates to a brushing device for machining workpieces, comprising a bundle of fiber rods arranged parallel to one another and a protective sleeve surrounding the fiber rods, which sleeve is axially adjustable relative to the fiber rods.
  • Such brushing directions are particularly used on machine tools to grind, polish or clean the surfaces of workpieces and to deburr or round off the edges of workpieces.
  • the fiber rods which may for example consist of a ceramic material, are subjected to wear during the said operations. Therefore, the extent to which the free ends of the fiber rods protrude beyond the protective sleeve must be adjusted periodically.
  • Bürst publisheden a holder carrying the fiber rods has a locking screw which extends through a longitudinal slot in the protective sleeve. To adjust the above measure, the locking screw is released, the protective sleeve axially displaced by an amount and then tightened the locking screws again. This requires for each adjustment manual intervention, which are associated with a standstill of the machine.
  • the document WO2015 / 178273A1 describes a Bürst driven with machine adjustment of the relative position of the protective sleeve and the fiber rods. This is made possible by a nut-spindle combination, which is connected to the fiber rods and the protective sleeve. To readjust the nut and the spindle must be rotated relative to each other, which is achieved by a relatively complex construction of the Bürst driving, which also makes the use of a standard tool holder for the Bürst adopted practically impossible.
  • the present invention seeks to eliminate the disadvantages of the known prior art and to propose a Bürst adopted that is simple and easy to use and manages without relatively rotatable parts.
  • the clamping mechanism allows in a simple way to lift the positive connection and make the adjustment.
  • the Bürst comprises a bundle of fiber rods 1, which is anchored in a holder 9.
  • the fiber rods 1 are enclosed by a protective sleeve 2, wherein their free ends protrude by an amount from the protective sleeve 2.
  • the holder 9 is connected to a shaft 12, which in turn is surrounded by a guide tube 4.
  • At the opposite end of the fiber rods Bürst driven is connected to a standard tool holder 10 type HSK (hollow shaft cone).
  • HSK high shaft cone
  • the protective sleeve 2 is connected to a housing 8 in which a clamping cone 3 is received, which is axially adjustable against the force of springs 11 and the protective sleeve 2 connects non-positively to the guide tube 4.
  • the clamping cone 3 is advantageously divided into, for example, four segments which are arranged around the guide tube 4 around.
  • the brushing direction is clamped in a tool axis of a machine tool and rotated about its longitudinal axis 15.
  • the fiber rods 1 are subject to wear which is compensated from time to time by increasing the amount by which the fiber rods 1 project beyond the protective sleeve to a desired amount.
  • the tool axis is moved with the Bürst founded to a fixed counter-bearing 7 and advanced in the direction of the longitudinal axis, come to the brush direction existing pressure pin 5 on a contact surface 6 of the thrust bearing to the plant.
  • the standing with the pressure pin 5 in contact clamping cone 3 is thus prevented from continuing to follow the axial movement of the tool axis.
  • the housing 8 together with the protective sleeve 2 follows this movement by a small amount, wherein the housing 8 relative to Clamping cone 3 shifts, thereby reducing its clamping force and thus solves the non-positive connection between the guide tube 4 and the housing 8 with the protective sleeve 2 arranged thereon.
  • the combination of tool holder 10, guide tube 4, shaft 12, holder 9 and fiber rods 1 of the axial movement of the tool axis continue to follow, whereby the distance between the free ends of the fiber rods 1 and the free end of the protective sleeve 2 increases.
  • the amount by which the free ends of the fiber rods 1 project beyond the free end of the protective sleeve 2 can be determined in a simple manner by means of a measuring device present on the machine tool, for example a laser measuring device. Once this amount falls below a predetermined value, the described adjustment is initiated.
