Description
Technical Field
The invention relates to the technical field of ultrasonic inspection, in particular to a water immersion ultrasonic waterproof positioning detection tool for a shell threaded viscose assembly.
Background
Ultrasonic inspection is a nondestructive inspection method for detecting internal defects of a workpiece, an ultrasonic flaw detector generates electric oscillation and is added to a transducer (probe), the probe is excited to emit ultrasonic waves, and meanwhile, an electric signal sent back by the probe is amplified and displayed in a certain mode. The reflection, transmission and attenuation characteristics of ultrasonic waves in the object are utilized to obtain information such as the existence of defects in the detected workpiece, the positions and the sizes of the defects and the like. The method of immersing the probe and the workpiece in a liquid and performing flaw detection using the liquid (typically water) as a couplant is called a liquid (water) immersion method. The water immersion method has stable coupling, can adopt an acoustic lens to focus to improve the sensitivity, has good repeatability of detection results, and is suitable for automatic flaw detection. The workpiece is generally immersed in water completely, and a method of locally spraying water can be adopted for large-sized workpieces.
In order to know the quality of the shell thread gluing component, a water immersion ultrasonic testing method is needed to detect the gluing condition in the connecting threads of the component. The assembly has small volume and is difficult to carry out ultrasonic detection by using a local water spraying method, so that when the assembly is detected at present, the whole assembly is immersed in water, and the immersed ultrasonic probe is also immersed in water, and the water is used as a conducting medium of ultrasonic waves for detection. However, this detection method is troublesome in practice, and the reason for this problem is that: 1. when the assembly is detected, water immersion detection can be performed only by detecting water loaded in the water tank; 2. the detected thread end surface of the component cannot be contacted with water, otherwise, the water can enter the thread of the component to directly influence the ultrasonic detection result, so that the component needs to plug the thread end surface by wax during immersion detection, and the wax is required to be removed after detection, and is difficult to remove cleanly; 3. because the assembly is complex, water is easy to remain in parts to cause corrosion after immersed water is detected, and a drying device is needed to be used for dehydrating and drying the assembly after the assembly is detected; 4. when the assembly is detected, the position of the assembly is manually adjusted, so that the center of the assembly is coincident with the rotation axis of the ultrasonic detection probe.
Therefore, when the shell thread viscose assembly is subjected to water immersion ultrasonic detection at present, devices or operations such as a water tank, a plugging device, a drying device, a manual adjustment assembly and the like are required to be detected, so that the problem of inconvenience in the ultrasonic detection process of the assembly is caused.
