ActiveCN105571808AReliable specimen clampingLow costShock testingStrength propertiesFatigue testingEngineering
The invention discloses a clamp with all-freedom constraints for an impact fatigue testing machine. A general clamp can not ensure reliable clamping under effects of reciprocating impacts of the impact fatigue testing machine, and even the clamp itself is damaged. The clamp of the invention is composed of a distance adjusting mechanism, an X-direction clamping mechanism, a Y-direction clamping mechanism, a Z-direction clamping mechanism and a Z-direction clamping and self locking mechanism, wherein the distance adjusting mechanism is used for adjusting the distance between two sample supporting seats to be applied to samples of different lengths; the X-direction clamping mechanism, the Y-direction clamping mechanism and the Z-direction clamping mechanism are used for clamping a sample to constrain all freedoms of the sample; and the Z-direction clamping and self locking mechanism is used for preventing the Z-direction clamping mechanism in the impact direction from getting loose. The clamp of the invention can be used for clamping a rectangular section sample for the impact fatigue testing machine, all freedoms of the sample can be constrained, and as the self locking device is arranged in the impact direction, the reliability and the safety of sample clamping can be ensured.
