Abstract
Bolzen, in seiner bestimmungsgemäßen Anwendung geeignet, mittels in seinem Inneren befindlichen Kugelsystems und elastischen Federbügeln Spannkräfte zur Fixierung des Bolzens gleichmäßig in die Umgebung einzutragen.Bolt, suitable for its intended use, by means of a ball system located in its interior and elastic spring clips, to evenly apply tensioning forces to fix the bolt in the environment.
Description
Stand der TechnikState of the art
Es sind vielerlei Spannbolzen, speziell für gelochte Schweiß- und Montagetische, bekannt. Diese Bolzen verwenden zum Verspannen der zylindrischen Bolzen in entsprechenden zylindrischen Ausnehmungen im Bolzen verschiebbare Kugeln. Diese werden zentrisch nach außen gedrückt und pressen sich dann meist an Schrägen an Bohrungen an bestimmungsgemäße Aufnahmen. Die Kugeln erzeugen beim Spannen in der Anlagefläche hohe Punktlasten. Deshalb kann dieses System nicht in druckempfindlichen Materialien verwendet werden. Oft sind die Kugeln mittels Gummiringen gegen herausfallen gesichert. Dieser Gummiring versprödet im täglichen Einsatz recht schnell, und die Kugeln können den Spannbolzen ungewollt verlassen. Diese konstruktiven Ausführungen werden von Nutzern als mangelhaft kritisiert.There are many clamping bolts, especially for perforated welding and assembly tables, known. These bolts use for displacing the cylindrical bolts in corresponding cylindrical recesses in the bolt sliding balls. These are pressed centrally outward and then squeeze most of obliquely to holes on intended recordings. The balls generate high point loads during clamping in the contact surface. Therefore, this system can not be used in pressure-sensitive materials. Often the balls are secured against falling out by means of rubber rings. This rubber ring embrittles quite quickly in daily use, and the balls can leave the clamping bolt unintentionally. These structural designs are criticized by users as deficient.
Die ErfindungThe invention
Der erfindungsgemäße Spannbolzen ist konstruiert, um weitestgehend ringförmig größere Flächen für den Krafteintrag beim Spannen des Bolzens die Kraft übertragen zu lassen. Gleichzeitig sichert er die im Inneren befindlichen Kugeln vor Verlust. Mit diesem Bolzen können auf Grund der vielfach größeren Druckfläche der verwendeten Federspannbügel, die aus Teilen eines Torus bestehen, auch in druckempfindlichen Materialien dauerhaft sicher große Spannkräfte übertragen werden. Das System ist wartungsfrei.The clamping bolt according to the invention is constructed so as to allow largely annularly larger surfaces for the application of force during clamping of the bolt to transmit the force. At the same time he secures the bullets inside from loss. Due to the much larger pressure surface of the used spring tensioning clamps, which consist of parts of a torus, this bolt can permanently safely transmit large clamping forces even in pressure-sensitive materials. The system is maintenance-free.
