Test stand for e.g. ball-joint pivot, has test specimen cradle comprising clamping device with fastening element, by which test specimen is selectively lockable and releasable, and tension-compression device actuated by element

The test stand (100) has a measuring head (102), and a test specimen cradle (104) provided for a test specimen (116) e.g. ball-joint pivot. The cradle has a clamping device (106) comprising a fastening element (112), by which the test specimen is selectively lockable and releasable. The clamping device has a tension-compression device (110), by which the test specimen is held at a test specimen bed (114) in a fixed position. The tension-compression device is formed as an ejection device for the test specimen, and is actuated by the fastening element. Die Erfindung betrifft einen Prüfstand (100) und eine Spannvorrichtung für einen Prüfstand. Um das Prüfen von Prüfkörpern (116), insbesondere Gelenken zu erleichtern, ist gemäß der Erfindung vorgesehen, dass die Spannvorrichtung ein Betätigungselement (112) aufweist, mit dem ein Prüfkörper (116) wahlweise arretierbar und lösbar ist.
