Definitions

  • the invention relates to a counter-wood device for woodworking machines with tenon and slot spindle, which has at least one counter-wood pivotable in the horizontal position in the working position against the end of a window wood, which is arranged on a horizontally movable holder.
  • the holder of the counter-wood is arranged on links running parallel to one another, so that the axis directions of the holder remain unchanged when pivoting in the horizontal plane.
  • a disadvantage of this known arrangement is that the carrier for the handlebars is arranged stationary on the machine housing is, so that movement of the tenon and slot spindle is only possible in the vertical direction. Lateral displacement of the spindle is not possible due to the fixed arrangement of the bracket.
  • the invention is accordingly based on the object of designing a counter-wood device of the type mentioned at the outset in such a way that movement of the tenoning and slot spindle transverse to its axis remains possible.
  • a ring connected to the fixed bearing is rotatably arranged concentrically to the tenon and slot spindle, on the outer circumference of which at least one bearing is arranged for a rotatably mounted disk carrying the support of the counterwood, which is connected via a flexible positive connection such as a toothed belt or a chain or the like is connected to a further disk of the same size which is arranged concentrically to the spindle and is stationary.
  • the holder for the counter-wood is always connected to the spindle or to its mounting, so that when the spindle is offset laterally, the counter-wood device follows this movement of the spindle.
  • the spindle can thus be moved laterally as required.
  • the pivoting in the horizontal plane can be carried out in various ways.
  • This external toothing can be formed, for example, by a chain, the individual links of which are attached to the outer circumference of the ring, for example by screwing or welding.
  • the ring can also be adjusted by hand using a lever or by a hydraulic or pneumatic cylinder engaging an arm.
  • two counter-timber devices can be arranged opposite one another on the ring, which is particularly important if, as proposed in another machine, the machining of the two ends of a window timber is carried out by different sides of the tools of the tenoning and slotting spindle.
  • a tenoning and slot spindle 1 is rotatably supported within a fixed bearing 2 by roller bearings 3, concentric with the tenoning and slot spindle 1 on the outer circumference of the bearing 2, a ring 4 is rotatably arranged with the interposition of bearings 5 so that it can be adjusted relative to the bearing 2.
  • the bearings 6 and 7 are arranged for a rotatable disk 10 which carries the holder 8 (cf. FIG. 1) of a counter lumber 9 and which is mounted on an axis 11 held in the bearings 6 and 7 (cf. FIG. 2 ) sits.
  • the counter-rotating device 8 and 9 carrying rotatable disc 10 is connected via a flexible positive connection 12, such as a toothed belt, a chain or the like, to another equally large, fixed disc 13 arranged concentrically to the tenon and slot spindle 1, the flexible connection 12 is guided over this disc, as shown in Fig. 1.
  • a flexible positive connection 12 such as a toothed belt, a chain or the like
  • the flexible form-fitting connection 12 remains at rest on the side of the disk 13 facing away from the counter-wood device and the connection 12 is opened onto the disk 13 or handled.
  • the disk 10 moving with the ring 14 is given a rotary movement which leads to the axes of the disk and the Counter wood device does not change direction despite the rotation of the ring 14. There is therefore a parallel displacement of these parts in the horizontal plane.
  • the ring 4 is provided with an external toothing in the form of a chain 15, the individual links of which are attached to the outer circumference of the ring, which can be done for example by screwing or welding.
  • Motor-driven pinions 18 can engage in this external toothing 15 in order to rotate the ring in the manner described.
  • the ring 4 can also be adjusted in another way, for example by means of a hand lever or by means of hydraulic or pneumatic cylinders which engage an arm. 16 are limit switches that limit the adjustment of the ring 4.
  • a second counter-wood device 17 is provided, which is opposite the first counter-wood device and which is also provided with a disk 19 rotatably mounted in bearings 20, wherein the disc 19 is seated on an axis 21 held by the bearings 20 (cf. FIG. 3).
  • the disk 19 is connected via a further flexible connection 22 to a further fixed disk 23 (cf. FIG. 3) which is arranged concentrically to the tenoning spindle, so that when the ring 4 is rotated, the counter-timbering device 17 is also displaced in parallel in the manner described .
  • the storage 2 was designated as stationary in this description, this only relates to the parts that are movable relative to this storage.
  • the entire tenoning and slotting unit can be movable relative to the machine housing.
