Description

Schrämwerkzeug mit schwingbar gelagerter Säge. -Die Erfindung betrifft eine Schrämmaschine mit hin und her schwingender Säge von guter Wirkung und leichter Bedienbarkeit. Schrämmaschinen mit schwingbar gelagerten- Sägeblättern sind an sich bekannt. Nach der Erfindung wird die am Ende eines Gestänges angeordnete schwingende Säge unmittelbar mit einem Antriebsmotor versehen. Es wird auf diese Weise am Ende des Gestänges aus Säge und Motor ein sicher arbeitender Schrämkopf gebildet, der - leicht gehandhabt werden kann. Insbesondere ist die Bedienung der ganzen Schrämvorrichtung von Hand möglich.Cutting tool with swinging saw. -The invention concerns a cutting machine with a swinging saw that works well and is lighter Usability. Cutting machines with swingably mounted saw blades are per se known. According to the invention, the oscillating arranged at the end of a rod Equip the saw directly with a drive motor. It will end up that way of the linkage from the saw and motor, a safely working cutter head is formed - can be handled easily. The operation of the whole cutting device is particularly important possible by hand.

Am Ende des Gestänges ist beispielsweise querverschiebbar ein Druckluftkolben angebracht, mit dem gelenkig ein in einem Schlitz des Sägeblattträgers eingreifender Hebel verbunden ist. Beim Hinundhergehen des Kolbens wird durch den Hebel ein Schwingen des Sägeblattes herbeigeführt. Die ganze Anordnung kann so schmal ausgeführt werden, daß der ganze Schrämkopf mittels des Gestänges in den Schram hineingeschoben werden kann.At the end of the linkage, for example, a compressed air piston is transversely displaceable attached, with the articulated one engaging in a slot of the saw blade carrier Lever is connected. As the piston goes back and forth, the lever causes it to swing the saw blade brought about. The whole arrangement can be made so narrow that the whole cutter head can be pushed into the scraper by means of the rod can.

In der Zeichnung ist eine Ausführungsform der Vorrichtung in zwei Schnitten dargestellt.In the drawing is an embodiment of the device in two Sections shown.

In dem am Ende des Gestänges a .angeordneten Kopf b ist der Halter c der Sägeblätter d, e um den Bolzen f schwingbar gelagert und außerdem der Zylinder g des die Säge antreibenden Kolbens h ausgebildet. An dem Mittelteil des Kolbens h ist ein Hebel i um den Bolzen k ausschwenkbar befestigt. Dieser He. bel greift in einen Schlitz des am Sägeblattträger d angebrachten Ansatzes m ein. Aus der Zeichnung ergibt sich ohne weiteres, daß beim Hinundhergehen des Kolbens h die Sägeblätter d und e hin und her geschwenkt werden. Die selbsttätige Umsteuerung des Kolbens h kann in beliebiger Weise, z. B. durch einen Schieber oder kraftschlüssig wie bei den bekannten Bohrhämmern, erfolgen.In the head b arranged at the end of the rod a, the holder c of the saw blades d, e is mounted so that it can swing around the bolt f and the cylinder g of the piston h driving the saw is also formed. A lever i is attached to the central part of the piston h so that it can pivot about the bolt k. This hey. bel engages in a slot in the attachment m attached to the saw blade carrier d . The drawing clearly shows that when the piston h goes back and forth, the saw blades d and e are swiveled back and forth. The automatic reversal of the piston h can in any way, for. B. by a slide or non-positively as in the known rotary hammers.
