Abstract

Die Erfindung betrifft ein rückstoßgedämpftes Druckluftschlaggerät, welches aus zwei in einem Zylinder angeordneten, in entgegengesetzte Richtungen von einem über einen Zuführungskanal eingespeisten Druckmittel bewegbaren Kolben, einem Schlagkolben und einem Ausgleichskolben, besteht, wobei außerdem jedem der Kolben im Zylinder vorgesehene Luftkanäle und dem Schlagkolben ein Döpper zugeordnet sind.The invention relates to a recoil-damped compressed air impact device, which consists of two arranged in a cylinder, in opposite directions from a fed via a supply port pressure piston movable piston, a percussion piston and a balance piston, wherein also each of the piston provided in the cylinder air ducts and the percussion piston an anvil assigned.

Während es Aufgabe der Erfindung ist, eine Lösung vorzuschlagen, mit der die Rückstoßdämpfung weiter erhöht und damit, ohne dass es zu einer Überbelastung der Gelenke des Industrieroboters kommt, das Druckluftschlaggerät als robotergeführtes Fügewerkzeug eingesetzt werden kann, sowie eine Verkantung des einzutreibenden Verbindungselements (z. B. Stanzniet) unterbunden und eine Anpassung der Schlagenergie an unterschiedliche Fügeaufgaben ermöglicht werden kann, wird diese dadurch gelöst, dass der Schlagkolben (9) und der Ausgleichskolben (10) in ein und demselben Zylinder (8) angeordnet sind, wobei dem Schlagkolben (9) eine mit dem Döpper (5) zusammenwirkende Kolbenstange (11) zugeordnet ist sowie der Zylinder (8) eine feststehende Kolbenstange (12) aufweist, auf der der Ausgleichskolben (10) verschiebbar geführt und der Zuführungskanal (13) für das einzuspeisende Druckmittel (14) in dieser Kolbenstange (12) vorgesehen und dabei deren kolbenseitiges Ende (15) sich bis in den Bereich zwischen den Schlagkolben (9) und den Ausgleichskolben (10) erstreckend ausgestaltet ist.

Figure imgaf001
While it is an object of the invention to propose a solution with which the recoil damping further increases and thus, without causing overloading of the joints of the industrial robot, the compressed air impact device can be used as a robot-guided joining tool, as well as a tilting of the einzutreibenden connecting element (z. B. punch rivet) and an adaptation of the impact energy to different joining tasks can be made possible, this is achieved in that the percussion piston (9) and the balance piston (10) in one and the same cylinder (8) are arranged, wherein the percussion piston (9 ) is associated with the striker (5) cooperating piston rod (11) and the cylinder (8) has a fixed piston rod (12) on which the compensating piston (10) displaceably guided and the supply channel (13) for the pressure medium to be fed (14 ) provided in this piston rod (12) while the piston-side end (15) until i n the area between the percussion piston (9) and the balance piston (10) is designed to extend.
