Vacuum chamber loading is to place the object under test in a closed vacuum chamber to achieve vacuum loading, but this loading method has limitations in the detection of internal defects of large outdoor objects; the previous portable vacuum loading method is often carried out on samples at fixed positions. Detection does not require mobile detection equipment and vacuum loading devices at all times, but this method has certain limitations when detecting large outdoor objects, and the rubber chassis of the vacuum cover can only achieve adsorption loading of flat objects, and cannot Adsorption loading is carried out on different curved surfaces. Therefore, it is of great significance and application prospect to study a vacuum loading detection device and detection method based on curvature adjustment.

The invention discloses a vacuum loading detection device and method based on curvature adjustment. The device comprises a moving trolley, mechanical arms, a curvature measuring mechanism, a vacuum loading mechanism, a detection head and a computer. The two mechanical arms and the computer are respectively arranged on a base on the upper surface of the moving trolley; the curvature measuring mechanism and the vacuum loading mechanism are respectively arranged at the free ends of the two mechanical arms; the computer is in communication connection with the curvature measuring mechanism and the vacuum loading mechanism, after the curvature measuring mechanism transmits measured curvature data to the computer, the computer feeds back the curvature data to the vacuum loading mechanism, and the vacuum loading mechanism carries out vacuum loading on different curved surfaces according to different curvature data; and the detection head is arranged at the center of the vacuum loading mechanism for internal defect detection. The problem that manual movement is needed in traditional vacuum loading is solved, and the detection efficiency is improved; and meanwhile, vacuum loading of different curved surfaces is realized by measuring the curvature of the curved surfaces in real time.
Description
technical field [0001] The invention relates to the technical research field of non-destructive testing equipment, in particular to a vacuum loading testing device and testing method based on curvature adjustment. Background technique [0002] Laser shear speckle interferometry is widely used in machinery, aerospace and other fields due to its advantages of high precision and full-field real-time measurement. The use of shear speckle interferometry for non-destructive testing requires external loads on the object to be tested. The loading methods include thermal loading, vacuum loading, vibration loading, etc., among which vacuum loading is the most widely used for loading testing. [0003] Conventional vacuum loading includes vacuum chamber loading and portable vacuum loading. Vacuum chamber loading is to place the object under test in a closed vacuum chamber to achieve vacuum loading, but this loading method has limitations in the detection of internal defects of large ou...
