PATENTAMT.PATENT OFFICE.
Die Erfindung bezweckt ein rasches Befestigen von Preßluftbohrmaschinen an Arbeitsstücken, wie Kessel, Schiffswände usw., wo bisher oft der Zeitverlust, der durch das Einspannen verursacht wurde, den Nutzen der Anwendung von Preßluftbohrmaschinen in Frage stellte.The invention aims to quickly attach pneumatic drilling machines to workpieces, such as boilers, ship walls, etc., where up to now the loss of time caused by clamping was often the case Benefit of the use of pneumatic drills called into question.
Die Einspannvorrichtung (Fig. i) besitzt ein oder mehrere mit Kautschuk a abgedichtete Saugnäpfe b, die nach Entleerung der Luft durch den äußeren Luftdruck an das Arbeitsstück angepreßt werden.The clamping device (Fig. I) has one or more suction cups b sealed with rubber a which, after the air has been emptied, are pressed against the workpiece by the external air pressure.
Die Preßluftbohrmaschine (Fig. 2) besteht aus mehreren Einzelmotoren c, die auf eine gemeinsame Welle arbeiten. Die Entleerung der Saugnäpfe der Einspannvorrichtung wird dadurch bewirkt, daß man die Einlasse eines oder mehrerer dieser Motoren c vermittels eines Dreiweghahnes d und eines geeigneten Schlauches e anstatt mit der Preßluftleitung, mit den Saugnäpfen b in Verbindung bringt. Läßt man dann die übrigen Einzelmotoren c durch die bei f eintretende Preßluft antreiben, so wirken die mit den Saugnäpfen in Verbindung stehenden. Motoren als Luftpumpen. Bei genügender Luftleere wird der Dreiweghahn d umgeschaltet und alle Motoren arbeiten auf den Bohrer. Durch die dritte Stellung des Dreiweghahnes d wird Preßluft in die Saugnäpfe gelassen , und die Vorrichtung kann entfernt werden.The air drill (Fig. 2) consists of several individual motors c, which work on a common shaft. The suction cups of the clamping device are emptied by bringing the inlets of one or more of these motors c into connection with the suction cups b by means of a three-way valve d and a suitable hose e instead of the compressed air line. If the remaining individual motors c are then driven by the compressed air entering at f , those connected to the suction cups act. Motors as air pumps. When the air is sufficiently empty, the three-way valve d is switched over and all motors work on the drill. The third position of the three-way cock d lets compressed air into the suction cups and the device can be removed.
Die Anpreßvorrichtung an und für sich, bestehend aus einem Bügel mit Saugnäpfen und ihre Befestigung am Werkstück durch Entleerung der Luft aus den letzteren, ist nicht neu; die neue Erfindung bezieht sich lediglich auf die besondere Ausbildung der Vorrichtung zur Herstellung der Luftleere.The pressing device in and of itself, consisting of a bracket with suction cups and their attachment to the workpiece by evacuating the air from the latter not new; the new invention relates only to the special training of the Device for creating the air void.
