Definitions

  • the invention relates to a milling machine, in particular a hand milling machine, for milling elongated holes, with a basic body, on the base and / or a workpiece to be milled contact surfaces to be created are arranged, and one in Feed direction displaceable on the main body of the drive unit, one drive motor and one in operation includes rotating output shaft, being with the output shaft one during the feed movement in front of the front of the body arriving milling tool is non-rotatably connectable.
  • Such a milling machine is for example from DE 690 22 076 T2 known.
  • Two workpieces made of wood, for example, can be connected to each other by means of a dowel connection.
  • This type of connection is common in furniture making, for example, if walls are perpendicular to each other or the like should be connected to each other.
  • Dowel holes are inserted into both workpieces, after which the dowels are inserted in the dowel holes of one workpiece and then with its area protruding from the workpiece the dowel holes of the other workpiece and in this fixed.
  • the dowels usually used have a circular shape Cross-section so that the dowel holes are circular.
  • dowels with an elongated cross-sectional shape so that dowel holes with elongated hole cross-section in the workpieces - in the present case called "elongated holes" - must be milled.
  • the object of the present invention based on a milling machine of the type mentioned create with itself in a simple manner Have slots that are as clean as possible.
  • the user only has to advance the drive unit in the feed direction. Otherwise, the milling machine can keep its position throughout Milling process maintained since the back and forth movement of the milling tool takes place within the machine, so to speak.
  • the cross drive device you can work with continuous feed motion, during which the rotating milling tool is constantly moving and moved here, so that a zigzag-like milling path results. As tests have shown, this milling process is essential quieter than the previous milling machines.
  • the workpiece that is shown schematically in FIGS. 1 and 5 3 is, for example, a furniture wall that is be connected at right angles to the standing furniture wall should. This connection is, as already mentioned at the beginning, with Made with the help of dowels, not shown, which one Have slot 2 corresponding cross-section.
  • the elongated hole 2 forms a dowel hole going into the depth of the workpiece 3, into which the one already connected to the other furniture wall Plug is inserted and glued.
  • the workpiece 3 is shown cut off in FIG. 5.
  • the elongated hole 2 shown is located in its end face 4 and forms the end hole of a front row of elongated holes.
