Description
Schlagkolben für Bohrhämmer mit Drallumsatz. Die Erfindung betrifft einen kurzen und widerstandsfähigen Schlagkolben für Bohrhämmer, deren Umsatzvorrichtung vorn liegt.Percussion piston for rotary hammers with twist conversion. The invention relates to a short and robust percussion piston for rotary hammers, their turnover device is in front.
Es ist bekannt, den Schaft von Schlagkolben mit einem Vierkantloch für den Bohrer zu versehen. Es ist weiter bekannt, Schlagkolben mit auf dem Schaft eingefrästen Drallnuten zu versehen, Neu ist, beides zu vereinigen, d. h. auf dem mit einem Vierkantloch versehenen Schaft,des Schlagkolbens außen zugleich die Drallnuten anzubringen. Durch diese Anordnung, die Drallnuten außen ungefähr an der Stelle anzulegen, wo sich das Vierkantloeh befindet, wird der Schlagkolben und damit der Bohrhaanmer bedeutend verkürzt.It is known to have the shaft of a percussion piston with a square hole to provide for the drill. It is also known to have a percussion piston on the shaft to provide milled twist grooves, what is new is to combine both, d. H. on the with a square hole provided shaft, the percussion piston on the outside at the same time the twist grooves to attach. Due to this arrangement, the swirl grooves on the outside approximately at the same point create where the square hole is, the percussion piston and thus the Bohrhaanmer significantly shortened.
In der Zeichnung ist eine Ausführungsform des neuen Schlagkolbens angegeben, wonach i der eigentliche Kolben, 2 der Schaft, 3 das Vierkantloch ist und q. die Drallnuten sind.In the drawing is an embodiment of the new percussion piston indicated, according to which i is the actual piston, 2 the shaft, 3 the square hole and q. the twist grooves are.
Es wird durch eine Umsatzvorrichtung, welche entsprechend in .die Nuten q. eingreift, der Kolben i während seines Hin- oder Herganges gedreht, wobei der Bohrer, der in dem Vierkantloch 3 des Schaftes steckt, mitgedreht wird.It is through a conversion device, which accordingly in .die Grooves q. engages, the piston i rotated during its reciprocation, wherein the drill, which is inserted in the square hole 3 of the shaft, is also turned.
