Description

  

  <B>Klemmvorrichtung für Bolzen.</B>         Gegenstand    der Erfindung ist eine Klemm  vorrichtung zum Festhalten von Bolzen, bei  der den festzuklemmenden Bolzen zu umfas  sen bestimmte Mittel vorgesehen sind, von  denen das eine um eine zur Aufnahmebohrung  für den Bolzen des andern exzentrisch lie  gende Achse gegenüber diesem Mittel drehbar  angeordnet ist, so dass durch Verdrehung der  Mittel gegeneinander eine     Klemmung    des von  ihnen umfassten Bolzens rechtwinklig zur     Bol-          zenachse    herbeigeführt werden kann.  



  Der Erfindungsgegenstand ist auf der  Zeichnung in zwei beispielsweisen Ausfüh  rungsformen dargestellt.  



       Fig.    1 zeigt in einem     Schnitt    einen mittels  der Mittel nach der ersten Ausführungsform  festgeklemmten Bolzen.  



       Fig.    2 ist ein Schnitt nach der Linie     A-A     der     Fig.1.     



       Fig.    3 zeigt in einem Schnitt einen Bolzen  mit zwei auf ihm festgeklemmten, ineinander  greifenden Klemmscheiben gemäss dem zwei  ten Ausführungsbeispiel.  



       Fig.    4 zeigt eine Stirnansicht zu     Fig.    3.  Der festzuklemmende Bolzen 1 beim Aus  führungsbeispiel gemäss     Fig.    1 und 2 besitzt  an seinem obern Ende einen     Sechskantkopf    2  und an seinem untern Ende einen exzentrisch  zur     Bolzenachse    angeordneten Zapfen 3.     Auf     dem     exzentrischen    Zapfen 3 ist eine Hülse 4  mit entsprechend exzentrischer Bohrung 5 an  gebracht. Der Bolzen 1 sowohl als die exzen  trische Hülse 4     sind    in der gleichen Bohrung 6    eines nicht weiter dargestellten Teils angeord  net, wobei die Hülse in die Bohrung 6 passt.

    Wird der Bolzen 1 mittels des     Sechskantkop-          fes    um seine Achse gedreht, so wird durch die  Exzentrizität     zwischen    ihm und dem Zapfen 3  die Hülse 4 bezüglich ihrer Bohrungsachse  exzentrisch in der Bohrung 6 gedreht und  klemmt den Bolzen senkrecht zu seiner Achse  in der Bohrung 6 fest, so dass er axial nicht  mehr verschiebbar ist. Um einen gleitenden  Sitz der exzentrischen Hülse 4 in der Boh  rung 6 zu erhalten, kann die Hülse 4 an einer  Stelle auf ihrer Länge aufgeschnitten sein.  



  Nach der zweiten Ausführungsform     (Fig.    3  und 4) sind auf dem Bolzen 1 zwei mittels  eines vorstehenden bzw. eines ausgesparten       Teils        ineinandergreifende    Ringe 7 und 8 an  geordnet. Die vom vorstehenden Teil des Rin  ges 7 gebildete Nabe ist exzentrisch zur Ring  bohrung 10 angeordnet, durch die der Bolzen  1. hindurchgesteckt ist. In gleicher Weise ist  die Bohrung des ausgesparten Teils 9 des. Rin  ges 8 mit gleicher Exzentrizität zu dessen  Ringbohrung 10 ausgeführt, so dass in einer  neutralen Stellung die gleich dimensionierten  Bohrungen 10 der beiden Ringe 7 und 8 über  einstimmen.

   Werden nun zum Festhalten des       Bolzens    1 die Ringe 7 und 8 gegeneinander       ,.-erdreht,    so klemmen sie sich zufolge der Ex  zentrizität ihrer     ineinandergreifenden    Teile  bezüglich der Bohrungen 10 rechtwinklig zur       Bolzenachse    auf dem Bolzen 1 fest, so dass sie  auf diesem in axialer Richtung festgehalten  sind.



  <B> Clamping device for bolts. </B> The subject of the invention is a clamping device for holding bolts, in which certain means are provided to encompass the bolt to be clamped, one of which is eccentric around a receiving bore for the bolt of the other lying axis is arranged rotatably with respect to this means, so that by rotating the means against each other, a clamping of the bolt encompassed by them can be brought about at right angles to the bolt axis.



  The subject of the invention is shown on the drawing in two exemplary Ausfüh approximate forms.



       Fig. 1 shows in a section a bolt clamped by means of the means according to the first embodiment.



       Fig. 2 is a section along the line A-A of Fig. 1.



       Fig. 3 shows in a section a bolt with two clamped on it, interlocking clamping discs according to the two th embodiment.



       4 shows an end view of FIG. 3. The bolt 1 to be clamped in the exemplary embodiment according to FIGS. 1 and 2 has a hexagonal head 2 at its upper end and a pin 3 arranged eccentrically to the pin axis at its lower end. On the eccentric pin 3 is a sleeve 4 with a corresponding eccentric bore 5 is brought to. The bolt 1 as well as the eccentric sleeve 4 are net angeord in the same bore 6 of a part not shown, the sleeve fits into the bore 6.

    If the bolt 1 is rotated about its axis by means of the hexagon head, the eccentricity between it and the pin 3 causes the sleeve 4 to be rotated eccentrically in the bore 6 with respect to its bore axis and clamps the bolt in the bore 6 perpendicular to its axis so that it can no longer be moved axially. In order to obtain a sliding fit of the eccentric sleeve 4 in the Boh tion 6, the sleeve 4 can be cut open at one point along its length.



  According to the second embodiment (Fig. 3 and 4) on the bolt 1 two by means of a protruding or a recessed part interlocking rings 7 and 8 are arranged on. The hub formed by the protruding part of the Rin ges 7 is eccentric to the ring bore 10, through which the bolt 1. is inserted. In the same way, the bore of the recessed part 9 of the ring 8 is executed with the same eccentricity to its ring bore 10, so that in a neutral position the equally dimensioned bores 10 of the two rings 7 and 8 match.

   If the rings 7 and 8 are now rotated against each other to hold the bolt 1, they are clamped on the bolt 1 at right angles to the bolt axis due to the eccentricity of their interlocking parts with respect to the bores 10, so that they are on this in the axial direction are held.
