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

At the pressure switch 44, the push switch 44 is triggered to control the rotation of the drive motor 6, and at the same time, the rubber roller 61 is also in contact with the rotating shaft of the drive motor 6; the rotating rod 5 drives the double U-shaped test block groove 2 to rotate to the lower end surface of the inner ring wall 33, during which the sensor 74 enters its detection range when the ultrasonic test block enters its detection range. When the double U-shaped test block groove 2 reaches the top of the receiving mechanism 7, the lifting cylinder 71 drives the lifting plate 72 to pass through the stepped shape to support the ultrasonic test block. At the same time, the switching turntable 212 is controlled to rotate, and the switching turntable 212 is rotated to the second side piece 2122 in the rotating space 2123; at this time, the rotating rod 5 rises, the slider 42 returns to its position, and the push switch 44 returns to its position; it is considered to have completed a flip and detection. If the gravity does not reach the preset value, the ultrasonic test block cannot completely compress the spring, so that the push switch 44 cannot be triggered, it can be manually assisted in pressing, and the subsequent receiving mechanism 7 is recycled and processed again.
