Bohr- und Schleifvorrichtung. Patentiert im Deutschen Reiche vom 22. Dezember 1909 ab. Drilling and grinding device. Patented in the German Empire on December 22, 1909.

Vorliegende Erfindung betrifft ein Bohr werk, welches auch als Schleifapparat dienen kann. Die Erfindung besteht in der besonderen Ausgestaltung einer Einrichtung, mittels welcher während des Betriebes der Durchmesser des von dem Werkzeuge beschriebenen Kreises verändert werden kann.The present invention relates to a boring mill, which can also serve as a grinding apparatus. The invention consists in the particular embodiment of a device by means of which the diameter of the circle described by the tool changed during operation can be.

Fig. ι zeigt die Vorrichtung in der Seitenansicht, und dieFig. Ι shows the device in side view, and the

ίο Fig. 2 bis 6 zeigen Längs- und Querschnitte durch die Vorrichtung.ίο Fig. 2 to 6 show longitudinal and cross sections through the device.

In einem Ständer ι ist die Bohrwelle 2 dreh- und verschiebbar gelagert. Die Drehbewegung der Bohrwelle wird durch Schneckenradantrieb 3 oder in sonst geeigneter Weise bewirkt. Der Kopf der Bohrwelle ist drehbar im Schlitten 4 gelagert, welch letzterer in der Führung des Ständers 5 durch Spindel 6 hin und her bewegt werden kann und so die Längsbewegung der Bohrwelle bewirkt.In a stand ι the drilling shaft 2 is rotating and slidably mounted. The rotary movement of the drilling shaft is driven by worm gear 3 or in any other suitable manner. The head of the drilling shaft can be rotated in the slide 4 stored, which the latter moves back and forth in the guide of the stand 5 through the spindle 6 can be and thus causes the longitudinal movement of the drilling shaft.

In der hohlen Bohrwelle 2 ist eine zweite hohle Welle 7 gelagert, welche als Einstellspindel für den Werkzeugträger dient, und in dieser Welle 7 ist wieder Welle 8 gelagert, welche die Schleifspindel 9 antreibt. Welle 8 erhält ihre Bewegung durch Riemenscheibe 10 oder in anderer Weise.In the hollow drilling shaft 2, a second hollow shaft 7 is mounted, which serves as an adjusting spindle for the tool carrier, and in this shaft 7 is again supported by shaft 8, which drives the grinding spindle 9. Wave 8 gets its movement through pulley 10 or in some other way.

Das untere Ende "der Bohrwelle 2 trägt einen Schuh 11, in welchem der Werkzeugträger 12 derart gelagert ist, daß er sich um eine Achse 13 dreht, welche exzentrisch zur Mitte der Bohrwelle 2 liegt. Im Werkzeugträger 12 ist ferner die Schleifspindel 9 wiederum exzentrisch zur Drehachse 13 des Werkzeugträgers gelagert.The lower end ″ of the drilling shaft 2 carries a shoe 11 in which the tool carrier 12 is mounted so that it rotates about an axis 13 which is eccentric to the center of the drilling shaft 2 lies. In the tool carrier 12, the grinding spindle 9 is again eccentric to Axis of rotation 13 of the tool carrier mounted.

Der Werkzeugträger 12 wird durch einen an ihm befindlichen Zahnkranz 14, in den das Triebrad 15 der Einstellspindel 7 eingreift, gedreht. Hierdurch wird derN^bstand der Achse der Spindel 9 von der Achse der Bohrwelle 2 ganz nach Bedarf eingestellt.The tool holder 12 is supported by a toothed ring 14 in which the Drive wheel 15 of the adjusting spindle 7 engages, rotated. This increases the distance of the axis the spindle 9 is adjusted from the axis of the drilling shaft 2 as required.

Die Übertragung der Bewegung von Welle 8 auf Schleifspindel 9 erfolgt durch Welle 16 mit Universalgelenken oder, wie in Fig. 6 dargestellt, durch die Räder 17-21.The transmission of the movement from shaft 8 to grinding spindle 9 is carried out by shaft 16 Universal joints or, as shown in Fig. 6, by the wheels 17-21.

Um während des Betriebes den Achsenabstand zwischen den Wellen 9 und 2 verändern zu können, trägt der Schlitten 4 einen Radkranz 22 und dieser wieder einen zweiten Radkranz 23. Beide haben gleiche Innenverzahnung, wobei aber zu beachten ist, daß der Zahnkranz 23 gegen den undrehbar mit dem Schlitten 4 verbundenen Zahnkranz 22 verdreht werden kann.To change the axis distance between the shafts 9 and 2 during operation can, the carriage 4 carries a wheel rim 22 and this again a second wheel rim 23. Both have the same internal toothing, but it should be noted that the ring gear 23 can be rotated against the toothed ring 22 connected non-rotatably to the carriage 4 can.

Die Bohrwelle 2 und die Einstellspindel 7 haben andererseits gleiche Außenverzahnung 24 bzw. 25.The drilling shaft 2 and the setting spindle 7, on the other hand, have the same external toothing 24 or 25.

Auf Bohrwelle 2 ist drehbar gelagert ein Arm 28, in welchen eine Welle mit zwei Stirnzapfen fest eingesetzt ist. Auf diesen Stirnzapfen sind drehbar angeordnet zwei gleich große Zahnräder 26, 27, welche also, wie aus der Zeichnung ersichtlich, einerseits in die Zahnkränze 22 und 23, andererseits in die Zahnräder 24 und 25 eingreifen.An arm 28, in which a shaft with two end journals is firmly inserted, is rotatably mounted on the drilling shaft 2. These trunnions are rotatably mounted two equal gears 26, 27, which, then, can be seen on the one hand as the other hand, engage the drawing, in the gear rings 22 and 23, with the gears 24 and 25th

Rad 23 ist auch noch außen mit einer Verzahnung versehen, in welche das Zahnrad 29 eingreift; welches durch Welle 30 gedreht wird (Fig. i).The wheel 23 is also provided on the outside with a toothing into which the gear 29 intervenes; which is rotated by shaft 30 (Fig. i).

Sobald nun Rad 29 bewegt wird, tritt eine Verdrehung der Zahnkränze 22 und 23 gegeneinander ein und damit auch der Welle 7 gegen Welle 2. Dadurch wird auch Rad 15 in Tätigkeit gesetzt und so der Kopf 12 um Achse 13 gedreht. Wenn Bohrarbeiten ausgeführt werden sollen, wird Schleifscheibe 31 entfernt und auf den Kopf 12 der Stahlhalter 32 aufgesetzt.
Um sich den eigenartigen Bewegungsvorgang
As soon as wheel 29 is moved, the sprockets 22 and 23 rotate against each other and thus also the shaft 7 against shaft 2. When drilling work is to be carried out, the grinding wheel 31 is removed and placed on the head 12 of the steel holder 32.
To feel the peculiar movement process

ίο klarzulegen, stelle man sich vor, daß Zahnkranz 23 stillsteht (ebenso wie Zahnkranz 22). Wenn sich nun Bohrwelle 2 dreht, so wird Rad 26 mitgedreht und wickelt sich auf Zahnkranz 22 ab, wodurch der Halter 28 eine um die Bohrwellenachse kreisende Bewegung erhält. Rad 27 muß dann naturgemäß die gleiche Bewegung wie Rad 26 machen, da es sich auf dem gleich großen Zahnkranz 23 abwickelt. Die Folge ist, daß sich Rad 25 mit gleicher Winkelgeschwindigkeit und in gleichem Sinne dreht, wie Rad 24. So lange also Zahnkranz 23 unbeweglich bleibt, wird Welle 7 sich stets mit gleicher Geschwindigkeit drehen, wie Welle 2 und es findet keine Beeinflussung des Zahnkranzes.14 durch Rad 15 statt. Wird dagegen Zahnkranz 23 gedreht, so muß naturgemäß eine Relativbewegung der Welle 7 gegen Welle 2 erfolgen und dadurch eine Verstellung des Werkzeugträgers herbeigeführt werden.To clarify, imagine that gear rim 23 stands still (as well as ring gear 22). If drilling shaft 2 now rotates, then Wheel 26 rotates and unwinds on the ring gear 22, whereby the holder 28 to a the drilling shaft axis receives circular motion. Wheel 27 must then of course be the same Make movement like wheel 26, since it unwinds on the gear ring 23 of the same size. The result is that wheel 25 moves with the same angular velocity and in the same sense rotates like wheel 24. So as long as ring gear 23 remains immobile, shaft 7 will always move with it Rotate at the same speed as shaft 2 and there is no influence on the ring gear. 14 by bike 15 instead. If, on the other hand, the ring gear 23 is rotated, then naturally a relative movement of the shaft 7 against shaft 2 takes place and thereby an adjustment of the Tool carrier are brought about.
