Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection equipment, in particular to an ultrasonic detection device based on solid coupling. Background Art

[0002] In existing technology, the testing solution for the part to be tested is to immerse the part and the ultrasonic probe in a reservoir filled with liquid couplant to isolate the air (the acoustic impedance matching between air and the part is poor during ultrasonic testing, and bubbles trapped at the interface significantly affect the scanning imaging). A single-element ultrasonic probe is used to perform reflection imaging analysis on the part to be tested, or two single-element probes are placed on either side of the part to be tested for transmission imaging analysis. The movement during the test process is as follows:

[0003] The part to be tested is immersed in liquid coupling agent and placed vertically and fixed. During the testing process, the probe moves back and forth in a certain plane to scan the part to be tested and obtain ultrasonic imaging in the corresponding scanning area.

[0004] However, during the testing process, the part to be tested needs to be completely immersed in the liquid coupling agent, which may contaminate the part to be tested itself. In addition, the liquid coupling agent may be easily brought out during the clamping operation of the part to be tested, thereby contaminating the testing equipment.

[0005] In summary, it is urgent to develop an ultrasonic detection device that does not directly contact the liquid coupling agent. Utility Model Content

[0006] In response to the shortcomings of the above-mentioned existing production technology, the applicant provides an ultrasonic testing device based on solid coupling, which can prevent the parts to be tested from directly contacting the liquid coupling agent, thereby avoiding contamination of the parts to be tested by the liquid coupling agent, and has wide applicability.

[0007] The technical solutions adopted in this utility model are as follows:

[0008] An ultrasonic detection device based on solid coupling includes a main body base, on which a first liquid reservoir assembly and a second liquid reservoir assembly are arranged. The first liquid reservoir assembly and the second liquid reservoir assembly are arranged vertically. After the first liquid reservoir assembly and the second liquid reservoir assembly move toward each other, they abut against each other and fit tightly together. A solid coupling flexible layer is attached to the opposing surfaces of the first liquid reservoir assembly and the second liquid reservoir assembly; a part to be tested is clamped between the first liquid reservoir assembly and the second liquid reservoir assembly, and a probe assembly is arranged above the part to be tested.

[0009] As a further improvement of the above technical solution:

[0010] Preferably, the relative motion between the first liquid reservoir assembly and the second liquid reservoir assembly is a linear motion.

[0011] Preferably, the second liquid reservoir assembly is mounted on the limiting support assembly, and the first liquid reservoir assembly is assembled on the driving assembly; the first liquid reservoir assembly is driven by the driving assembly and moves in the direction facing the opposite surface of the second liquid reservoir assembly.

[0012] Preferably, the first liquid reservoir assembly is matched with a guide assembly in the direction of movement; during the relative movement of the first liquid reservoir assembly and the second liquid reservoir assembly, the first liquid reservoir assembly in motion is guided by the guide assembly.

[0013] Preferably, during the relative movement of the first reservoir assembly and the second reservoir assembly, the solid coupling flexible layer on the opposite surfaces between the first reservoir assembly and the second reservoir assembly abuts against and clamps the part to be tested.

[0014] Preferably, the cavities of the first liquid reservoir assembly and the second liquid reservoir assembly are both filled with liquid coupling agent, ensuring that the liquid level exceeds the uppermost end of the part to be tested, and the probe assembly extends into the liquid coupling agent and is located on both sides of the part to be tested for ultrasonic testing.

[0015] Preferably, the probe assembly includes a base body, a slide rail arranged on the base body and extending in a straight direction, and a slide table slidably arranged on the slide rail; a mounting frame is provided on the slide table, and a first probe and a second probe arranged opposite to each other are respectively configured on the mounting frame, and the first probe and the second probe respectively match and correspond to the first liquid reservoir assembly and the second liquid reservoir assembly.

[0016] Preferably, the first probe and the second probe are located on both sides of the part to be measured and are displaced up, down, left, and right in a plane.

[0017] Preferably, the first liquid reservoir assembly is provided with a force sensor for detecting the pressure on the part to be tested on a side away from the second liquid reservoir assembly, so as to detect the part to be tested under different pressure conditions.

[0018] Preferably, a limiting unit is provided on the side of the second liquid reservoir assembly away from the first liquid reservoir assembly, and the limiting unit abuts against the second liquid reservoir assembly during the relative movement of the first liquid reservoir assembly and the second liquid reservoir assembly, so that the second liquid reservoir assembly always maintains a vertical setting state.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model has a compact structure. Through the clamping fit between the two liquid reservoirs and the provision of a solid coupling flexible layer on the contact surface with the part to be tested, the probe assembly extends into the liquid coupling gel in the liquid reservoir to perform ultrasonic detection. During the entire process, the part to be tested does not come into contact with the liquid coupling agent, so the part to be tested will not be contaminated.
