Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ultrasonic flaw detection, in particular to an ultrasonic flaw detector coupling agent automatic supply device. BACKGROUND

[0002] Industrial flaw detection is an important means to ensure the safe service of industrial equipment, and is widely used in daily inspection and detection of various equipment. At present, there are many methods of industrial flaw detection, among which ultrasonic flaw detection is the most frequently used in industrial flaw detection because it can detect internal defects without damaging the device. In the process of ultrasonic detection, the ultrasonic flaw detector needs to emit ultrasonic waves into the detected part, and then receive the emitted sound waves to determine whether there are internal defects. In order to improve the transmission of sound energy between the probe and the workpiece, improve the sound intensity of ultrasonic waves on the detection surface, and improve the detection accuracy. Therefore, in the actual detection process, a layer of coupling agent needs to be applied between the probe and the workpiece to ensure the normal development of the detection work. If the coupling agent is not applied between the probe and the workpiece during the detection process, the sound energy cannot be effectively transmitted to the inside of the workpiece, resulting in the inability to carry out the detection work. At the same time, uneven application of coupling agent still leads to the inability to effectively measure local defects, thereby reducing the detection accuracy and leading to the inability to effectively measure the defects of the workpiece.

[0003] In the actual ultrasonic detection work, the coupling agent needs to be applied on the surface of the workpiece by artificial, and then the detection probe is used to reciprocatingly detect the surface of the workpiece. The process of artificial application of coupling agent mainly includes holding a brush in one hand to apply and holding a coupling agent barrel in the other hand. In this way, the labor intensity of artificial detection is increased, and the uniformity of application is insufficient due to the inability to sense the content of coupling agent on the brush, or repeated application is required, thereby reducing the overall work efficiency and work quality, which also affects the efficiency and accuracy of subsequent ultrasonic detection work.

[0004] Therefore, an ultrasonic flaw detector coupling agent automatic supply device is needed to solve the above problems. UTILITY MODEL CONTENTS
