Description

Schnelleinspannvorrichtung für Flach- und Rundstäbe an Zerreißmaschinen. Die Erfindung stellt eine neuartige Schnelleinspannvorrichtung für Flach- und Rundstäbe ohne Schultern bei Zerreißmaschinen dar; welche in erster Linie zu sogenannten Schnellversuchen verwendet werden soll.Quick clamping device for flat and round bars on shredding machines. The invention provides a new type of quick clamping device for flat and round bars without shoulders in shredding machines; which primarily to so-called rapid tests should be used.

Der Erfindungsgegenstand ist in den Abbildungen, teilweise im Schnitt, dargestellt, und zwar zeigt: Abb. i eine Vorderansicht, Abb. z eine Seitenansicht und Abb. 3 einen Querschnitt im GrundriB.The subject of the invention is shown in the figures, partly in section, shown, namely: Fig. i is a front view, Fig. z is a side view and Fig. 3 is a cross-section in plan.

In die vertikale, genau zentrische, mit seitlicher öffnung versehene Bohrung des Spannkopfes wird das einseitig offene Rundkeillagen L eingesetzt und durch sogenannten Bajonettverschluß in seiner Lage festgehalten. Die beiderseitigen Spannkeile S' und SZ sind durch Rundführungen im Keillager und durch die Kugellenker K im Handhebel h derart gelagert, daB sie sich den mehr oder minder unebenen, auch windschiefen Enden der Prüfstäbe genau anpassen können. Durch die vertikal, genau zentral angeordnete Feder f wird der Handhebel h niedergehalten, so daB beim Loslassen desselben ohne weiteres ein. zentrisches. Festhalten und Klemmen der Prüfstäbe ermöglicht ist. Die beiden rückwärts herausziehbaren Federbolzen b ermögliehen eine rasche Auswechselung der beiden Spannkeile mit ihren Kugellenkern, so daß die jeweils erforderlichen Spannkeile rasch ohne Herausnahme des Keillagers selbst eingesetzt werden können.The round wedge layer L, which is open on one side, is inserted into the vertical, precisely centered bore of the clamping head, which is provided with a lateral opening, and is held in its position by a so-called bayonet lock. The clamping wedges S 'and SZ on both sides are supported by round guides in the wedge bearing and by the ball link K in the hand lever h in such a way that they can be precisely adapted to the more or less uneven, even crooked ends of the test rods. The hand lever h is held down by the vertically, precisely centrally arranged spring f , so that when it is released it is easily activated. centric. Holding and clamping of the test rods is enabled. The two backward pull-out spring bolts b allow a quick exchange of the two clamping wedges with their ball links, so that the clamping wedges required in each case can be inserted quickly without removing the wedge bearing itself.

Einseitig offene Keillager sind an sich bei Ei-nspannvorrichtungen für Prüfstäbe bekannt. Auch sind Kugellenker zum Verbinden der Spannkeile mit dem Handhebel bereits verwendet worden. Die Vorteile der neuen Bauart liegen in der Vereinigung beider Vorrichtungen mit der Rundführung der beiden Spannkeile, wozu als weitere Verbesserungen die zentrale Feder für den Handhebel und die dem Handhebel parallel liegenden, daher leicht herausz,iehbaren Federbolzen hinzukommen.Wedge bearings that are open on one side are inherently in clamping devices known for test rods. There are also ball links to connect the clamping wedges with the Hand lever has already been used. The advantages of the new design lie in the Combination of both devices with the round guide of the two clamping wedges, including as further improvements the central spring for the hand lever and the hand lever spring bolts that are parallel and therefore easy to pull out are added.

PATENTANSPRÜCHE: r. SchnelleinspannvorrichtungfürFlach-@und Rundstäbe ohne Schultern bei Zerreißmaschinen, dadurch gekennzeichnet, daß das einseitig vorn offene Keillager durch Baj onettverschluß in der vertikalen Bohrung dr-s; Spannkopfes genau zentrisch gelagert ist, für dessen Spannkeile eine runde Führung sowie eine Kugelaufhängung im Handhebel vorgesehen ist, derart, daß eine selbsttätige Einstellung je nach Beschaffenheit und Lage der Endflächen der Prüfstäbe erfolgt, welche eine genau achsiale Beanspruchung gewährleistet. a. Vorrichtung nach Anspruch r, gekennzeichnet durch eine vertikale, genau zentral wirkende Belastungsfeder des Handhebels, vermöge deren das ganze System mit genauem Zwangsschluß arbeitet. 3. Vorrichtung nach Anspruch r, dadurch gekennzeichnet, daß die Spannkeile im Handhebel derart aufgehängt sind, daß durch einfaches Zurückziehen der Federbolzen eine rasche Auswechselbarkeit der Keile ermöglicht ist. PATENT CLAIMS: r. Rapid clamping device for flat and round bars without shoulders in tearing machines, characterized in that the wedge bearing, which is open on one side at the front, is secured by bayonet lock in the vertical bore dr-s; Clamping head is mounted exactly centrally, for the clamping wedges a round guide and a ball suspension is provided in the hand lever, so that an automatic setting takes place depending on the nature and position of the end faces of the test rods, which ensures an exactly axial load. a. Device according to claim r, characterized by a vertical, precisely centrally acting loading spring of the hand lever, by virtue of which the entire system works with an exact positive connection. 3. Apparatus according to claim r, characterized in that the clamping wedges are suspended in the hand lever in such a way that a quick interchangeability of the wedges is made possible by simply pulling back the spring bolts.
