Description
Kugelkontaktklemme Die Erfindung betriff eine Kugelkontaktklemane mit zwei um einen Bolzen zangenartig verschwenkbarenm Backen und mit einem senkrecht zur Achse des Bol zens längs einer Spindel- verstellbaren Konus, auf dem die hinteren Enden der Backen gleiten.
Bei einer solchen bekannten Klemme ist der Konus rund ausgebildet und weist ein Innengewinde auf, mit dem der Konus auf der Spindel geschraubt werden kann.
Wegen der runden Form dies Konus liegen die hinteren Enden dar Backen. nur punktförmig auf dem Konus auf, so dass der Druck zwischen den hinteren Endren der Backen und dem Konus sehr gross ist, was zu einem starken Verschleiss der Konusfläche führt.
Anch müssen die hinteren Enden der Backen über einen langen Weg, nämlich längs einer Spirale, auf dem Konus gleiten,
um ein geringes Spreizen der Backen zu erreichen.. Für diesen langen Weg muss deshalb eine grosse Kraft aufgewendet werden, um die Reibung zwischen den, hinteren Enden der Backen und dem Konus zu überwinden.
Der Erfindung liegt die Aufgabe zugrunde, die Nach- teile der bekannten Kugelkontaktxlämnne zu vermeiden, wofür erfindungsgemäss vorgeschlagen wird, dass der Konus die Form eines Keils hat,
der in der Breite den hinteren Enden der Backen angepasst ist,, und dass der Keil mit geringem Spiel auf der Spindel in Längsrichtung gleitet und mit einer auf der Spindel geführten Schraub hülse drehbar verbunden ist.
Durch diese Ausbildung ergibt sich zweckmässig eine linienförmige Berührung zwischen den hinteren Enden der Backen und dem. Ko nus, was zu.
einem geringeren Druck zwischen diesen Teilen führt. Der Keil wird lediglich ein Längsrichtung der Spindel bewegt, so dass die hinteren Enden der Backen auf dem Keil nur einen geradlinigen, kurzen Weg zurück legen..
Der Vorschub des Keils wird durch die mit 'hm drehbar verbundene Schraubhülse hervorgerufen.
Um beim Zurückschrauben des Konus der bekannten Klemme ein selbsttätiges Öffnen der Backen zu erreichen, sind in der Klemme Federn vorgesehen,
welche die Bak- ken auseinanderdrücken. Wegen der Drehbewegung des Konus ist auch eine zwangsläufige Führung der hinteren Enden der Backen an dem Konus gar nicht möglich.
Wenn dagegen gemäss der Erfindung ein lediglich in Längsrichtung dich bewegender Keil verwendet wird, ist es möglich,
die Federn. der bekannten Klemme weg- zulassen und das öffnen der Backen zwangsläufig her- beizuführen, wobei eine Weiterausbildung der Erfindung vorsieht;
dass die Backen an den hinteren Enden seitlich abstehende Stifte aufweilsen und dass an den Seiten des Kefls die Stifte aufnehmende Schlitze angebracht sind. In diesen Schlitzen
am Keil werden die Stifte der hin- teren Enden der Backen zwangsläufig geführt.
Vorzugsweise sind die Schlitze durch an den. Seiten das Keiles befestigte, umgebogene Bleche gebildet. Beispielhafte Ausführungsformen der Erfindung sind in der Zeichnung dargestellt,
und zwar sind Fig. 1 ein Längsschnitt durch eine Kugelkontakt- klamme mit geöffneten.
Backen, Fig. 2 eine Seitenansicht der Kugelkontaktldemme nach Fig. 1, angesetzt an einem Kugelkopf, Fig. 3 eine Vorderansicht einer anderen Ausführungs- form der Kugelkontaktklemme,
angesetzt an einem Ku- gelkopf, und Fig. 4 ein Querschnitt längs der Linie IV-IV in Fig. 3. Die Klemme nach den Fig. 1 und 2 dient zum An- setzen an dienRTI ID="0001.0254" WI="16" HE="4" LX="1321" LY="2149"> Kugelkopf 1.
Die Klemme besteht aus zwei Backen. <I>2</I> und 3, die um den Bolzen. 4 zangenartig verschwenkbar sind. Von dem Bolzen geht eine Spindel 5 aus, auf der die Schmub- hülse 6 geführt ist.
An der Schraubhülse 6 .ist mittels eines Kragens der Keil 7, der de Spindel 5 mit geringem Spiel umgibt,
drehbar befestigt. Die Breite des Keils 7 entspricht der Auflagebreite der hinteren Enden 8 und 9 der Backen 2 und 3 (Fig. 2).
Die Klemme nach den Fig. 3 und 4 wird :in gleicher Weise an dem Kugelkopf 1 angesetzt und besteht aus den beiden, um den Bolzen 4 schwenkbaren Backen 2 und 3.
Auf der Spindel 5 ist ebenfalls eine Schraubhülse 6 geführt, an welcher der Keil 7 drehbar befestigt ist, auf dem die hinteren Enden 8 und 9 der Backen 2 und 3 gleiten. An den hinteren Enden 8 u. 9 der Backen 2 u. 3 sind seitlich abstehende Stifte 11, 12, 13 und 14 ange bracht.
An den Seiten des Keä#s 7 sind der Form des Keils angepasste, umgebogene Bleche 15 und 16 mittels Nieten 17 und 18 befestigt.
Die umgebogenen Teile der Bleche ergeben Schlitze, die parallel zur Keilfläche ver- laufen und in denen die Stifte 11, 12, 13 und 14 gleiten.
Beim Abwärtsbewegen des Keils 7 gleiten die Stifte 11, 12, 13 und 14 zwangsläufig an den umgebogenen Teilen der Bleche 15 und 16, wodurch die hinteren Enden 8 und 9 der Backen 2 und 3 aufeinander zu bewegt werden und somit die Backen 2 und 3 den Kugelkopf 1 freigeben.
Ball contact clamp The invention relates to a ball contact clamp with two jaws pivotable around a bolt like pliers and with a cone which is adjustable perpendicular to the axis of the bolt along a spindle and on which the rear ends of the jaws slide.
In such a known clamp, the cone is round and has an internal thread with which the cone can be screwed onto the spindle.
Because of the round shape of this cone, the rear ends lie on the jaws. only punctiformly on the cone, so that the pressure between the rear end of the jaws and the cone is very high, which leads to severe wear on the cone surface.
Also, the rear ends of the jaws must slide over a long way, namely along a spiral, on the cone,
in order to achieve a slight spreading of the jaws. For this long distance, therefore, a great deal of force must be expended in order to overcome the friction between the rear ends of the jaws and the cone.
The invention is based on the object of avoiding the disadvantages of the known Kugelkontaktxlämnne, for which it is proposed according to the invention that the cone has the shape of a wedge,
which is adapted in width to the rear ends of the jaws, and that the wedge slides with little play on the spindle in the longitudinal direction and is rotatably connected to a screw sleeve guided on the spindle.
This design results in a useful linear contact between the rear ends of the jaws and the. Ko nus what to.
less pressure between these parts. The wedge is only moved in a longitudinal direction of the spindle so that the rear ends of the jaws only cover a short, straight path on the wedge.
The advance of the wedge is brought about by the screw sleeve rotatably connected to 'hm.
In order to achieve an automatic opening of the jaws when screwing back the cone of the known clamp, springs are provided in the clamp.
which push the jaws apart. Because of the rotational movement of the cone, an inevitable guidance of the rear ends of the jaws on the cone is also not possible.
If, on the other hand, according to the invention, a wedge that only moves in the longitudinal direction is used, it is possible
the feathers. omit the known clamp and inevitably bring about the opening of the jaws, a further development of the invention provides;
that the jaws have laterally protruding pins at the rear ends and that the pin-receiving slots are made on the sides of the kefl. In these slots
the pins of the rear ends of the jaws are inevitably guided on the wedge.
Preferably the slots are through to the. Sides of the wedge attached, bent sheets formed. Exemplary embodiments of the invention are shown in the drawing,
1 is a longitudinal section through a ball contact clamp with an open one.
Jaws, FIG. 2 a side view of the ball contact terminal according to FIG. 1, attached to a ball head, FIG. 3 a front view of another embodiment of the ball contact terminal,
attached to a ball head, and FIG. 4 shows a cross section along the line IV-IV in FIG. 3. The clamp according to FIGS. 1 and 2 is used for attachment to the RTI ID = "0001.0254" WI = "16" HE = "4" LX = "1321" LY = "2149"> ball head 1.
The clamp consists of two jaws. <I> 2 </I> and 3 that are around the bolt. 4 are pivotable like pliers. A spindle 5, on which the push-on sleeve 6 is guided, extends from the bolt.
The wedge 7, which surrounds the spindle 5 with little play, is attached to the screw sleeve 6 by means of a collar.
rotatably attached. The width of the wedge 7 corresponds to the support width of the rear ends 8 and 9 of the jaws 2 and 3 (Fig. 2).
The clamp according to FIGS. 3 and 4 is: attached in the same way to the ball head 1 and consists of the two jaws 2 and 3 pivotable about the bolt 4.
A screw sleeve 6 is also guided on the spindle 5, to which the wedge 7 is rotatably attached, on which the rear ends 8 and 9 of the jaws 2 and 3 slide. At the rear ends 8 u. 9 of the jaws 2 u. 3 laterally protruding pins 11, 12, 13 and 14 are introduced.
On the sides of the key 7, bent sheets 15 and 16 adapted to the shape of the wedge are fastened by means of rivets 17 and 18.
The bent parts of the metal sheets result in slots that run parallel to the wedge surface and in which the pins 11, 12, 13 and 14 slide.
When the wedge 7 is moved downwards, the pins 11, 12, 13 and 14 inevitably slide on the bent parts of the sheets 15 and 16, whereby the rear ends 8 and 9 of the jaws 2 and 3 are moved towards one another and thus the jaws 2 and 3 Release ball head 1.
