[0001] The present invention relates to the technical field of non-destructive testing block detection devices, and in particular to a flip auxiliary detection device for ultrasonic test blocks and a method of using the same, which is suitable for ultrasonic testing blocks that are thicker, heavier, and need to be flipped. Background Art

[0002] Ultrasonic test blocks are test pieces with simple-shaped artificial reflectors designed and manufactured for certain purposes. Ultrasonic testing uses test blocks as a basis for comparison. There are various known features on the test blocks, such as specific dimensions to create fixed acoustic features; or flat-bottomed holes, grooves, slits, etc. of a certain size. Since the test block is the basis for debugging the ultrasonic device, during the production process of the test block, defects such as flat-bottomed holes, grooves, and slits will produce certain weight deviations in manufacturing. Due to the deviation in the weight of the test block, sometimes it will cause fundamental errors when testing and debugging the ultrasonic device. Therefore, it is necessary to perform weight detection on the ultrasonic test block, and after the detection, it is usually necessary to flip the ultrasonic test block for operation. However, most of the detection devices in the prior art are not compact enough, and they are all separately provided with weight detection devices and flipping devices, which occupy a large space. A single flipping device or manual flipping is laborious, so it is necessary to design a labor-saving and compact ultrasonic test block auxiliary detection device. Summary of the invention
