Description

Spannvorrichtung zum elastischen Spannen von Werkzeugen mit konischen Schäften (Bohrern, Fräsern, Reibahlen und so weiter).Clamping device for elastic clamping of tools with conical Shanks (drills, milling cutters, reamers and so on).

Das DBP Nr. 820 667 wird bei mir hergestellt. Der Versuch, Bohrer größeren Durchmessers zu gebrauchen, scheiterte. Ich habe daraufhin ein Spannfutter entwickelt, das wesentliche Verbesserungen aufweist, welche ich nachstehend schildere.The DBP No. 820 667 is manufactured by me. Trying to drill to use larger diameter failed. I then have a chuck developed, which has significant improvements, which I describe below.

Die Erfindung betrifft nicht nur ein Bohrfutter, sondern ein Spannfutter, das zum Bohren, Fräsen, Aufreiben und Gewindeschneiden gebraucht werden kann und alle Werkzeuge mit Konusschäften aufnimmt.The invention relates not only to a drill chuck, but to a chuck, that can be used for drilling, milling, reaming and thread cutting and takes all tools with conical shanks.

Im Gegensatz zu den üblichen Konushülsen, die ja nur eine starre Festhaltevorrichtung darstellen, werden die Werkzeuge jetzt mit Hilfe einer Gummispannhülse gespannt, und zwar elastisch gespannt, und mitgenommen.In contrast to the usual conical sleeves, which only have a rigid retaining device the tools are now clamped with the help of a rubber clamping sleeve, and that is elastically stretched and taken along.

Das Hauptmerkmal der Erfindung besteht darin, daß die Konusschäfte der Werkzeuge in feste Gummispannhülsen mit starken, anvulkanisierten Metallringes gesteckt und mit der am Ende der Vorrichtung befindlichen Mutter je nach Bedarf fest angespannt werden. Durch dieses elastische Spannen ist die Beschädigung der Konusschäfte beseitigt und ein Abbrechen der Werkzeuge völlig ausgeschlossen.The main feature of the invention is that the conical shafts of the tools in solid rubber clamping sleeves with strong, vulcanized metal rings plugged in and with the nut located at the end of the device as required be tightly tensed. This elastic tensioning prevents damage to the Tapered shafts eliminated and breaking of the tools completely excluded.

Was durch diese Erfindung an Kosten für die Beschaffung von Werkzeugen erspart wird, ist nicht zu ermessen. Hinzu kommt noch, daß jetzt lappen-und konusbeschädigte Werkzeuge ohne Nacharbeit wieder verwendet werden können.What with this invention in terms of costs for the procurement of tools is saved is not to be measured. In addition, flaps and cones are now damaged Tools can be used again without rework.

Die Anschaffung eines Spannfutters ist oft schon beim Einsparen eines teuren Werkzeuges wettgemacht. Die Gummispannhülsen sind so eingerichtet, daß fast der ganze Konus in Gummi gelagert ist, und sie üben einen solchen Druck aus, daß unter den schwersten Bedingungen gearbeitet werden kann.The acquisition of a chuck is often the same as saving one expensive tools made up for. The rubber clamping sleeves are set up so that almost the whole cone is mounted in rubber, and they exert such a pressure that can work under the most difficult conditions.

Bei übergroßen Beanspruchungen kann die Gumispannhülse zu reiben beginnen und unbrauchbar werden. Es geht aber nicht, wie bei den bisher üblichen Spannvorrichtungen, das meist sehr teure Werkzeug zu Bruch. Der Preis einer Gummispannhülse beträgt nur einen geringen Bruchteil des Preises für ein neues Werkzeug.In the event of excessive stress, the rubber clamping sleeve can begin to rub and become unusable. But it does not work, as with the previously common clamping devices, the usually very expensive tool broke. The price of a rubber clamping sleeve is only a small fraction of the price of a new tool.

Im Spannkörper 1 wird die Gummispanûhülse mit den anvulkanisierten Metallscheiben nach dem Einführen des mit einem Konus versehenen Werkzeuges mit der Mutter angezogen. Durch das Anziehen der Mutter wird ein so starker Druck erzeugt, daß das Werkzeug mitgenommen wird. Das Auswechseln ist denkbar einfach : Die Mutter wird etwas gelost CD und das Werkzeug einfach herausgezogen. CD Zu jedem Spannfutter gehören zwei Gummispannlülsen mit zwei verschie- denen Konusbohrungen. Dadurch ist es möglich, mit nur drei Spann- CD futtern alle Werkzeuge von Morsekonus 1 bis 5 zu verwenden. In the clamping body 1, the rubber clamping sleeve with the vulcanized metal washers is tightened with the nut after the tool with a cone has been inserted. Tightening the nut creates so much pressure that the tool is carried along. Replacing it is very easy: the mother is drawn a little CD and the tool simply pulled out. CD Each chuck has two rubber clamping sleeves with two different which conical bores. This makes it possible to use only three clamping CD chuck to use all tools from morse taper 1 to 5.

Gebrauchsmusterschutzansprüche
1) Der Schaft des Spannfutters wird mit zwei Löchern versehen, damit die Luft, welche beim Einführen des Werkzeuges sonst zusammengepreßt würde, entweichen kann. s 2) Die Gummispannhülen sind außen zylindrisch und innen konisch.
3) Die Gummispannhülsen sind so lang, daß der Lappen des Konusschaftes heraussteht, womit erreicht wird, daß sowohl fabrikneue, als auch lappenbeschädigte Werkzeuge gespannt werden kön- non
Utility model protection claims
1) The shaft of the chuck is provided with two holes so that the air, which would otherwise be compressed when the tool is inserted, can escape. s 2) The rubber clamping sleeves are cylindrical on the outside and conical on the inside.
3) The rubber clamping sleeves are so long that the flap of the conical shaft protrudes, which means that both brand-new and flap-damaged tools can be clamped. non
