Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, and in particular to a test block support. Background Technology

[0002] With the development of nondestructive testing technology, ultrasonic testing has been increasingly applied in various fields. A basic ultrasonic testing system consists of an ultrasonic testing instrument, a suitable detection device (sensor), a suitable scanning system (manual or automatic), and a reference standard test block (comparison test block). The reference standard test block (comparison test block) is used to adjust the sensitivity and testing range of the testing system, and to evaluate the magnitude and location of discontinuities, ensuring the reproducibility of the test results.

[0003] Currently, the reference standard test blocks (comparison test blocks) used in the aerospace industry are typically sets of 19 flat-bottomed hole standard test blocks manufactured according to ASTM E127, "Standard Specification for Manufacturing and Control of Flat-Bottomed Hole Ultrasonic Standard Test Blocks." During scanning, the system scans flat-bottomed holes of the same diameter but different burial depths one by one, testing the maximum amplitude of the ultrasonic response of the flat-bottomed holes. The maximum amplitude is set at 80% FSH, and the maximum amplitude fluctuation range is ±5% of the 80% FSH response. The fluctuation should be within the range of 76% to 84%. The system automatically records the gain value, and saves the test results after the test is completed.

[0004] During routine scanning, flat-bottomed hole test blocks need to be placed one by one on a plane underwater. In order to improve scanning speed and efficiency, ultrasonic testing systems have begun to adopt automatic scanning. The system is required to simultaneously collect the maximum amplitude of ultrasonic response of flat-bottomed holes at different burial depths in one automatic scan. This requires that the test surfaces (upper surfaces) of all test blocks should be on the same horizontal plane and the flat-bottomed holes should be on the same horizontal line. However, due to the different heights of the test blocks, the system needs to be manually adjusted one by one during scanning, resulting in low efficiency. Utility Model Content

The upper surface of support b3 has several steps b4, each step b4 having a countersunk hole b5.

The difference between the height of the second-to-last step b4 and the height of the last step b4 is 6.3 mm.

[0024] In this embodiment, the height of step a7 at the highest point of support a2 is lower than the height of step b4 at the lowest point of support b3. Specifically, the height difference between step a7 at the highest point of support a2 and step b4 at the lowest point of support b3 is 6.3 mm.
