Fuel element grillwork strip buckling looseness detection tool and method

The invention belongs to the technical field of nuclear fuel element detection, and particularly relates to a fuel element grillwork strip buckling looseness detection tool and method. With the grillwork strip buckling looseness detection tool adopted, a sample is always subjected to balanced downward pressure without the action of other forces in a test process. Effective clamping of the sample is realized; a grillage strip is effectively fixed in the clamp, and the height of the grillage strip is controlled by a spring part; and a welding tongue piece can be effectively fixed, the strip can be effectively supported. The detection tool and method can be used for a buckling looseness test of the sample. 本发明属于核燃料元件检测技术领域，具体涉及一种燃料元件格架条带扣松检测工装及方法。本发明提供了格架条带扣松工装，样品在试验过程中始终受均衡的下压力而无其它力的作用。实现了样品的有效夹持，格架条带在夹具内有效固定，弹簧部位控制其高度；可以实现对焊舌片的有效固定和对条带的有效支撑，能够用于样品的扣松试验。
