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 thread adhesive assembly.
Background
Ultrasonic inspection is a nondestructive method for detecting internal defects of workpieces, in which an ultrasonic flaw detector generates electric oscillation and applies the electric oscillation to a transducer (probe), the probe is excited to emit ultrasonic waves, and an electric signal sent back by the probe is amplified and displayed in a certain mode. The reflection, transmission and attenuation characteristics of the ultrasonic wave in the object are utilized, so that the information of the defect, the position, the size and the like of the defect in the detected workpiece is obtained. A method of immersing a probe and a workpiece in a liquid and performing flaw detection using the liquid (generally, water) as a coupling agent is called a liquid (water) immersion method. The water immersion method has stable coupling, can adopt an acoustic lens to focus and improve the sensitivity, has good repeatability of detection results, and is suitable for automatic flaw detection. Generally, the workpiece is completely immersed in water, and a local water spraying method can be adopted for large workpieces.
In order to know the quality of the shell thread viscose assembly, a water immersion ultrasonic inspection method is adopted to detect the viscose coating condition in the connecting thread of the assembly. The module has small volume and is difficult to carry out ultrasonic detection by a local water spraying method, so that the whole module is immersed into water, a water immersed ultrasonic probe is also immersed into the water, and the water is used as a conducting medium of ultrasonic waves for detection when the module is detected at present. However, this detection method is also troublesome in actual implementation, and causes such problems are: 1. when the assembly is detected, water immersion detection can be carried out only by detecting water loaded in the water tank; 2. the detected thread end face of the component cannot contact water, otherwise, the water can enter the thread of the component to directly influence an ultrasonic detection result, so that the thread end face of the component needs to be plugged by wax during immersion detection, and the wax needs to be removed after detection and is difficult to remove completely; 3. because the assembly is complex, water is easy to remain in the parts to cause corrosion after immersion water detection, and a drying device is needed to carry out dehydration and drying 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 coincided with the rotating axis of the ultrasonic detection probe.
Therefore, when carrying out water logging ultrasonic testing to casing screw thread viscose subassembly at present, there need to detect devices or operations such as basin, shutoff, drying device, manual adjustment subassembly, has leaded to the inconvenient problem of this subassembly ultrasonic testing process.
