Description
Die Erfindung ist eine Drahtformfeder-Sicherung für Maschinenschrauber-Werkzeuge, welche die Verbindung zwischen Verbindungsvierkant und maschinenbetätigten Werkzeugen herstellt.The invention is a wire form spring lock for machine screwdriver tools, which creates the connection between the connecting square and machine-operated tools.
Bisher wurden für die Verbindung Maschine-Werkzeug die Verbindungsstifte und 0-Ri.nge nach DIN 3129 verwendet. Diese Befestigungsart hat Nachteile. Ein schneller Wechsel des Werkzeuges ist durch die 2-teilige Sicherung nicht möglich. Außerdem steht der O-Ring über dem Außendu-,hmesser des Werkzeuges. Es kommt oft vor, daß bei sehr engen Einbauverhäitnissen der O-Ring von dem Werkzeug abgestreift wird. Bei Mehrfachschraubern ist die Montage uno Demontage aes O-Ringss nur inter großem Zeitaufwand möglich. Eine Weitung des Q-Ringes durch Alterung, Öl und falscher Montage ooer mecnanische Beschädigung sind weitere Nachteile.Until now, connecting pins and O-rings according to DIN 3129 were used to connect the machine and tool. This type of fastening has disadvantages. A quick change of the tool is not possible due to the 2-part lock. In addition, the O-ring is above the outer diameter of the tool. It often happens that the O-ring is stripped off the tool in very tight installation conditions. With multiple screwdrivers, the assembly and disassembly of the O-ring is only possible with great expenditure of time. Widening of the O-ring due to aging, oil and incorrect assembly or mechanical damage are further disadvantages.
Ein RET-Ring (Patent-Nr. 4266453) mit und ohne Stahlstift, eignet sich durch die umständliche Montage und Demontage ebenfalls nicht für den einfachen Wecnsel oer Werkzeuge.A RET ring (patent no. 4266453) with and without a steel pin is also not suitable for easy tool changing due to the complicated assembly and disassembly.
Der Erfindung liegt die Aufgabe zugrunde, die vorstehend genannter- Nachteil-· bei oer Verbindung zwischen Verbindungsvierkant und Werkzeug zu beseitigen uno eine Verbindung zu schaffen, die einfach in der herstellung, einfach und sicher in der Wirkungsweise und in der Kontags und Demontage ist.The invention is based on the object of eliminating the above-mentioned disadvantage in the connection between the connecting square and the tool and of creating a connection which is simple to manufacture, simple and safe in its operation and in connection and disassembly.
Erreicht ist dieses Ziel dadurch, oab die Drahtformfeoer-Sicherung in der Bohrung des Werkzeuges und im durchgehenden Stiftloch des Verbindungsvierkantes sicher steckt und somit ein Abgleiten des Werkzeuges vom Verbinüungsvierkant verhindert.This goal is achieved by ensuring that the wire form safety device is securely inserted into the bore of the tool and into the through-hole pin of the connecting square, thus preventing the tool from slipping off the connecting square.
Die Ausführungsform»wie in den Ansprüchen 1 bii 3 dargestellt ,erfüllt voll die gestellte Aufgabe.The embodiment as shown in claims 1 to 3 fully fulfills the stated task.
In der Zeichnung ist sie bisnerige Befestigung sowie der Erfindungsgegenstand, auch in einem Ausfünrungsbeiepiel in Schnitten, dargestellt.The drawing shows the fastening method as well as the subject matter of the invention, also in an example embodiment in sections.
Die Erfindung wird an einein Ausfuhrungsbeispiel unter Hinweis auf uie beigefügte Zeichnung Deschrieben:The invention is described using an exemplary embodiment with reference to the attached drawing:
Fiy.1 zeigt die Verbindung zwischen Verbindungsvierkant und Werkzeug mittels Verbindungböti f t una O-Ring für Innenvierkante b,j bis 2bmm nach DIN 315I9.Fig.1 shows the connection between connecting square and tool using connecting bolts and O-rings for internal squares b,j up to 2bmm according to DIN 315I9.
Fig. Z zeigt die ürahtformfeuer-bicherung in montiertem Zustand. Durch aie Bohrungen!«») unci(b) uie nach DIN 31 c 1 una DIN 31^9-Form F- festgelegt sind, wird die v-törmig gebogene iJrahtformfeder eingeführt. Mit dem Durchm. C wird die voihanoene Rille umschlossen,wotJti der Federweg von A zu B und wieaer zu A ci.it einem leid, ten Druck aes Daumens überwunden wird. Dadurch wird die urantformfeüer-Sicherung in ihrer Lage auch bei höheren Drehzahlen in inrer Position festgenalten.Fig. Z shows the wire-form fire safety device in the assembled state. The V-shaped wire-form spring is inserted through the holes 1(b) and 1(c) as defined in accordance with DIN 31 c1 and DIN 31^9-form F-. The diameter C encloses the entire groove, so that the spring travel from A to B and back to A is overcome with a gentle pressure of the thumb. This holds the wire-form fire safety device in its position even at high speeds.
bei einer = ehr hohen Belastung können 2 ituc* Drahtformfeder-Sicherungen nebeneinander eincejetzt weraen(b).At a very high load, 2 wire form spring fuses can be installed next to each other (b).
Eine Demontage aer iJrahtformfeuer-^icherung erfolgt durch EinstLcken und Crücken von hand eines geeigneten Stifte= aer etwas kj.eint.r im Durchmesser als die ciurcncehende Sti f tloi_hbonrung( b) des Verbindungsvierkentes sein mub. Mach uberwindunc der F'eoijrunc im Durcnrnesser B ist aie Verbindung gelöst.The wire-form fire safety device is dismantled by inserting and manually twisting a suitable pin which must be slightly smaller in diameter than the adjacent pin hole ( b ) of the connecting square. Once the hole in diameter B has been overcome, the connection is released.
fin.j zeict aie Form der Drahtformteuer-Sicherunc. Die werte für üurchm.C unc Hone E erceüen sich aurcn die angegeDenen Mabe für Innenvierkante nach DlN 3129. Der Crantaurchmesser wiro aer ertaraerlichen Feaerungskraft angeglichen, ibt aber so bemessen, aab der Aubsendurchmesser der Ural tform^· feder-iicherung unter dem Aubsendurchmesser des Werkzeuges liegt. Der Winkelef und das Mad A an den abgerunoeten Enden der Drahtformfeder-Sicherung sino so abgestimmt, daü auf jeden Fail die Enden fest am Innendurchmesser der Werkzeugrille anliegen.fin.j shows the shape of the wire form spring lock. The values for diameter C and height E are based on the dimensions given for internal squares according to DIN 3129. The diameter is adjusted to the required cutting force, but is dimensioned so that the outside diameter of the wire form spring lock is less than the outside diameter of the tool. The angle f and the diameter A at the rounded ends of the wire form spring lock are adjusted so that the ends always fit tightly against the inside diameter of the tool groove .
Bei sachgemäßem Gebrauch, Ausdrucken durch einen Stift durch die 5tiftlochbohrung(5), ist eine Verletzungsgefanr ausgeschlossen.When used properly, by pushing a pen through the pin hole (5), there is no risk of injury.
