Abstract:
1. A device for quality testing sheet metal parts with a testing device, comprising: a frame having at least two receptacles for mounting the sheet metal part, a pulse generator that excites the sheet metal part to oscillate, an elastomer bearing attached to the frame and to feet secured on a floor or on a machine part so as to decouple oscillations of the sheet metal part from the floor or the machine part, a sound sensor that picks up a sound profile caused by the oscillations of the sheet metal part, and an evaluation unit that compares the recorded sound profile with a reference curve and generates a signal with which the sheet metal parts are classified, characterized in that sheet metal parts can be fed to the testing device in a clock cycle controlled fashion, wherein sheet metal parts whose recorded sound profile does not lie in a tolerance range of the reference curve can be eliminated by a sorting device.
