Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic automatic inspection, in particular to an automatic ultrasonic flaw detection device. Background Art

[0002] Ultrasonic flaw detection involves an operator moving a probe over the workpiece surface, inch by inch. The flaw detector emits an ultrasonic signal and returns it to the testing equipment. The returned signal is used to determine the presence of defects beneath the metal. This process involves the operator feeling across the workpiece surface inch by inch. If the probe does not fully cover the workpiece, it can easily lead to missed detections. Employees determine possible defects based on the waveforms on the workpiece surface. Individual experience varies, making misjudgments easy. Varying detection speeds and the waveforms received by the equipment can also lead to misjudgments.

[0003] When optimizing existing automated ultrasonic flaw detection equipment, most of the improvements are reflected in the effects of the device. For example, the Chinese utility model patent with publication number CN201910297338.0 discloses an "ultrasonic flaw detection device". This utility model patent sets up a telescopic structure. When the probe touches the boss of the workpiece, it can generate a trigger signal, thereby causing the control device to perform an in-and-out retraction action to avoid damage to the probe. If the telescopic structure generates trigger signals multiple times, it can sense that the surface of the workpiece is uneven, and the device can automatically adjust the height relationship between the probe and the workpiece.

[0004] Although the above method has certain advantages in terms of improvement, it still has certain disadvantages: if the flaw detection device is not activated, the flaw detection head can only detect one part of the workpiece. If other parts are not detected, the detection data will be inaccurate. If other parts are to be detected, personnel need to move the workpiece, which may require a lot of manpower.
