Definitions

  • Such milling machines are used for cleaning, roughening or removing concrete, asphalt or metal surfaces.
  • they have a drum which is rotated and equipped with milling wheels.
  • milling wheels On the circumference of flanges, which close such drum-like cages on the front sides or reinforce in the middle axes are mounted on which several freely rotating milling wheels are lined up.
  • Such tools are presented, for example, in EP0661144 ( Figures 5 & 6).
  • Drums used for finishing work are equipped with tungsten carbide or diamond cutting tools at the circumference and at the end faces.
  • the present invention now has the task to improve a universal milling machine of the type mentioned so that the advantages of the known stable milling machines for large areas remain and at the same time a greater flexibility is achieved by the corner and edge areas and the lateral Borders and edges can be subjected to machining.
  • the presented milling machine for edge and corner areas is constructed on a base frame 1.
  • a base frame 1 As shown in Figure 1, 1, two guide wheels 3 and a drawbar 2 are attached to this base frame.
  • This base frame 1 has a gallows-like stem 8, which is provided with a slot. The direction of this slot is in the continuation of the drawbar, in the direction of travel of the guide wheels 3.
  • a bracket 6, On the gallows-like stem 8 is in the assembled state, a bracket 6, which in turn represents an angle whose front leg 9 is vertical. At this front leg 8, a support roller 4 is attached.
  • the lying on the stem 8 of the base frame 1 leg of the holder 6 also has a slot whose width is exactly above the slot of the stem 8, but whose length is designed so that holder 6 relative to the base frame 1, a movement of the assembled state ( FIG. 1) can be pulled apart into the state during the conversion (FIGS. 2 and 3), in that the connecting screw 7 only has to be loosened and not removed.
  • the base frame 1 and holder 6 are guided, for example, by spring and groove such that they can only be displaced in the extension of the drawbar, but not in the transverse direction.
  • a connecting screw 7 is inserted through the slot provided in both parts.
  • this connecting screw 7 has an external thread, which fits into a corresponding internal thread in the transmission flange 22.
  • a flange whose diameter is certainly greater than the width of the slots in stem 8 and holder 6, and on this flange a large ring is fixed at right angles, which allows the manual operation of this connecting screw 7.
  • the connecting screw 7 is secured against complete removal. It can not be removed from the transmission flange 22 without special tools.
  • the milling unit 21, 22, 23 is held together by the gearbox flange 22.
  • a gear 25 On one side of the gear flange 22 of the electric motor 21, secured against rotation, fixed.
  • the drive shaft of the electric motor 21 is positively and non-positively connected to the transmission 25.
  • the electric motor 21 can be operated with the same force in both directions of rotation.
  • the milling tool 23 On the same axis A, on the side opposite the electric motor 21 side of the transmission flange 22, there is the milling tool 23. This is fixedly connected to the output shaft of the transmission 25 and rotatably mounted in the transmission flange 22.
  • the milling tool 23 is surrounded by a Staubabsauggeh 24. This has a nozzle 26 to which any commercial industrial vacuum cleaner can be attached.
