Definitions

  • FIG. 5 represents a front view of the device of FIG. 4.
  • FIG. 1 represents a view of fins 1 forming part of a pack 2 of fins (see FIG. 2) each fin has at its top 3 several pins 4.
  • the pins 4 can be inserted into the holes 5 of a bandage 6 .
  • the carriage 14 is provided with rollers 16 which move on the edges of two vertical circular segments 17 integral with two vertical uprights 34 of a support 18. It also includes rollers 19 which move on the surface of the vertical uprights 34.
  • the plate 11 is oriented so that the axis of the riveting head 9 forms with the vertical plane P orthogonal to the axis of the rotor an angle c equal to the angle made by the axis of the tenons 4 with the same plane .
  • the inclined parts 24 are parallel to the plane P and the flanges 23 are parallel to the axis of the head 9. These flanges 23 have been chosen taking into account the angle c of inclination of the let's stick 4.
  • a retractable endoscope 32 In front of the bolt 10 is mounted a retractable endoscope 32 under the effect of a jack 33 mounted on the riveting head 9 by a link 35.
  • the endoscope passes through the opening 31.
  • the process according to the invention is as follows.
  • the rotor is arranged with its horizontal axis, the pack 2 of fins mounted on a wheel 7 of this rotor is brought by rotation of the rotor in a substantially horizontal position.
  • the pins 4 of the fins form an angle c with the vertical plane P of symmetry of the wheel of which the pack 2 of fins is part.
  • the endoscope is adjusted to the position of a tenon 4 of the horizontal fin.
  • the axis of the head 9 is thus in the extension of the axis of the tenon 4.
  • the horizontal and vertical movements of the head 9 are clamped by clamping devices (not shown).
  • the jaw 25 is applied against a group of fins (for example five fins) by operating the motor 26.
  • the other jaw 27 is applied by the jack 28 against the group of fins thus clamping this group of fins.
  • the end piece 29 is applied against the tire 6, the endoscope 32 still being in position.
  • the endoscope 32 is raised and the actual riveting is carried out.
  • the snap 10 comes into contact with the post 4 and, by a concentric movement at the periphery of the post 4, flattens the latter.
  • the duration and the force applied can be precisely adjusted to take account of the studs used.
  • the snap 10 then automatically moves away from the pin 4.
  • the bandage 6 is unclamped by moving the end piece 29 back.
  • the group of fins is unclamped by spreading the jaws 27 then 25; then we unbridle the vertical and horizontal movements of the riveting head 9.
  • the endoscope 32 is replaced, which is centered on another tenon 4 and so on.
  • the displacement of the riveting head 9 is easy when passing from the lug of one fin to the corresponding lug of another fin since they are located in the same vertical plane; it then suffices to move the carriage 14 along the circular segments 17 to pass from one stud 4 to another.
  • the axis of the riveting head 9 is no longer chosen in a horizontal plane passing through the axis of the rotor (where it can move by rotation of the plate) but in a plane passing through the 'axis of the rotor and making an angle close to 45 ° to 90 ° with the horizontal plane.

  1. Verfahren zur Vernietung einer Bandage (6) auf einer Schaufel (1) eines Rads (7) eines Rotors mit waagrechter Achse (xx'), wobei jede Schaufel (1) an ihrer Spitze (3) einen oder mehrere Zapfen (4) aufweist, die in eines oder mehrere Löcher (5) der Bandage eingeführt werden können, wobei man gemäß diesem Verfahren
    - einen Nietkopf (9) für ein bestimmtes Rad (7) so einstellt, daß er sich einerseits gemäß einer kreisförmigen Richtung bewegen kann und dabei in der Nähe der Spitzen (3) der Schaufeln (1) des Rads (7) vorbeiläuft, und daß andererseits seine Achse sich in der Verlängerung der Achse des Zapfens (4) befindet, wenn er über einem Zapfen (4) steht, und
    - dann die folgende Gruppe von Nietvorgängen durchführt:
    - man zentriert einen ersten Zapfen (4) vor dem Nietkopf (9),
    - man spannt die Bandage (6) gegen die Spitze (3) der Schaufel (1) fest,
    - man vernietet den Zapfen (4),
    - man gibt die Bandage (6) wieder frei,
    - dann verschiebt man den Kopf (9) derart, daß ein zweiter Zapfen (4) vor dem Nietkopf (9) angeordnet wird,
    - man beginnt die Gruppe von Nietvorgängen von neuem, bis alle Zapfen (4) einer Bandage (6) derart behandelt wurden, dadurch gekennzeichnet, daß man, wenn die Zapfen einen spitzen Winkel c mit der Mittelebene P des Rads (7) orthogonal zur waagrechten Achse (xx') bilden,
    - den Kopf (9) gegen senkrechte und waagrechte Bewegungen vor dem Vernieten festspannt und eine Gruppe von Schaufeln (1) zusammenspannt, die die mit dem Nietkopf (9) zu bandagierende Schaufel (1) enthält, und dann nach dem Vernieten
    - die Gruppe von Schaufeln (1) und die senkrechten und waagrechten Bewegungen des Kopfes (9) freigibt.
  2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß man ein Endoskop verwendet, das vom Kopf (9) getragen wird, um diesen auf einen Zapfen (4) zu zentrieren.
