Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing, in particular to a curved surface nondestructive testing frame. Background Art

[0002] Nondestructive testing refers to the method of inspecting and testing the structure, state and type, quantity, shape, nature, position, size, distribution and changes of defects inside and on the surface of the test piece by using physical or chemical methods, with the help of modern technology and equipment, under the premise of not damaging or affecting the performance of the tested object and not harming the internal organization of the tested object, without damaging the internal structure of the tested object. With the development of modern science and technology, the use of nondestructive testing frames is becoming more and more frequent, and the functions of the upper end are gradually increasing, so that it can better meet the needs of use.

[0003] In view of this, Chinese patent number CN111781273A proposes a curved surface non-destructive testing frame, which pushes multiple groups of support plates to move out of the hydraulic groove. The support plates at different positions intersect with the curved plate at different positions when rising. The curved plate limits the support plate through the pressure of the clamping plate until the support plate contacts the bottom end of the curved plate through the rubber head opened at the top, so that the multiple groups of support plates form the shape of the bottom end of the curved plate. However, the existing testing frame usually rotates the curved workpiece during the testing process. However, when rotating a workpiece with a small arc angle, it is easy to lose the center of gravity and cause the workpiece to fall. Therefore, a self-rotatable and adjustable testing structure is required. Utility Model Content
