TECHNICAL FIELD
[0001] The utility model relates to the technical field of ultrasonic detection, specifically to a kind of annular forging ultrasonic detection accessory and probe. BACKGROUND
[0002] Due to the characteristics of the working condition, most of the annular forgings today require ultrasonic testing (UT detection) of internal defects. Two types of probes are used for UT detection of annular forgings. One is a slant probe for scanning the inner and outer walls of the annular part, and the other is a straight probe for scanning the end face. Whether it is a slant probe or a straight probe, it needs to be in direct contact with the annular part through a coupling agent, or to be protected by a silicone soft film and directly contacted with the annular part.
[0003] However, during UT detection, due to the rough surface of the annular part and the different curvatures of the annular part, the probe wears out quickly and the single curvature detection of the probe is a problem, which seriously affects the detection results and the frequency and applicability of the probe. With the improvement of customers' quality requirements for UT detection, imported probes are needed to detect the annular part, thereby increasing the detection cost. Therefore, many annular forging enterprises use another way to paste a suitable size of organic glass in front of the probe, and then process the organic glass to reduce the service life of the probe. The disadvantage of this method is that the pasted organic glass causes refraction and reflection of the ultrasonic beam at the incident interface, causing attenuation of the ultrasonic energy and reduction of the detection capability, and affecting the determination of defect equivalent.
[0004] Recently, some enterprises have adopted a new way to detect annular forgings using non-contact water immersion ultrasonic detection. The annular part is placed in a coupling liquid tank, and the probe forms a coupling liquid layer with the annular part, achieving the effect of avoiding contact between the probe and the annular part. The disadvantage of this method is that the size of the annular part is not fixed, the size of the coupling liquid tank cannot be determined, and the hoisting of the annular part is difficult, etc. On the other hand, this device cannot be moved flexibly, the cost is very expensive, and it is easy to be damaged, etc. SUMMARY
[0005] In view of the defects of the prior art, the utility model provides an annular forging ultrasonic detection accessory and probe, which can form a coupling agent layer between the ultrasonic detection probe and the surface of the annular forging, avoid direct contact between the probe and the annular forging, reduce the contact area between the ultrasonic detection accessory and the ultrasonic detection probe and the annular forging, reduce the sliding resistance, move more conveniently and facilitate operation.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific details described herein without departing from the scope of the present application. It will be apparent to one of ordinary skill in the art that the present application can be practiced without some or all of these specific details. In other instances, well known structures have not been described in detail in order to not unnecessarily obscure the present application.
[0033] Reference is made to Figure 1, the structure schematic diagram of the annular forge piece ultrasonic detection accessory in one embodiment of the utility model is shown, which is a hollow columnar body 100, and has a first end 110 and a second end 120 opposite to each other, the first end 110 is equipped with a port 111 for the ultrasonic detection probe 200 to be installed, and the second end 120 is equipped with a contact surface 121 matched with the surface of the annular forge piece 10; when the ultrasonic detection probe 200 is installed in the port, the ultrasonic detection probe 200 and the inner wall of the hollow columnar body 100 form a cavity 130 containing the coupling agent 20.

[0037] For reference Figure 3 and Figure 5 In one embodiment, the curved surface is matched with the outer diameter surface 12 of the annular forge piece 10.
[0038] When specifically arranged, the structure of the contact surface 121 is determined according to the surface structure of the forge piece; when the inner diameter of the annular forge piece 10 is measured, the contact surface 121 is a curved surface, and the curvature is determined according to the inner diameter of the annular forge piece 10; when the outer diameter of the annular forge piece 10 is measured, the contact surface 121 is a curved surface, and the curvature is determined according to the outer diameter of the annular forge piece 10. The annular forge piece ultrasonic detection accessory reduces the contact area of the ultrasonic detection accessory and the annular forge piece 10, processes the circular arc curvature, further reduces the sliding resistance, reduces the influence of the multi-material curvature on the refraction and reflection of the ultrasonic wave, and improves the detection data precision.
[0039] In another embodiment, the contact surface 121 is a plane; the plane is matched with the end surface of the annular forge piece 10.
[0040] Need to explain, it can not only detect the outer diameter of the ring-shaped forging 10, but also can be processed into a convex arc curvature, the inner diameter of the ring-shaped forging 10 is detected, and it can also be processed into a plane, the end surface of the ring-shaped forging 10 is detected, the device is relatively simple to operate, the cost is relatively low, the type can be changed quickly, and it can be reused.

[0042] In an embodiment, the hollow cylindrical body 100 is an aluminum alloy workpiece or an organic glass workpiece.
[0043] In the above embodiment, the ring-shaped forging ultrasonic detection accessory is made of aluminum alloy or organic glass, so that the grinding modification is facilitated, that is, the curvature of the second end 120 of the ring-shaped forging ultrasonic detection accessory is modified, the curvature can be modified at any time, the corresponding ultrasonic detection accessory can be manufactured according to the product batch specification, and the wear and tear of the ring-shaped forging ultrasonic detection accessory is related to the use frequency, the manufacturing cost is relatively low, and the ring-shaped forging ultrasonic detection accessory can be mass-produced and then modified according to the specifications of the ring-shaped forging.
[0044] Referring to Figure 4 and Figure 5 , an embodiment of the ring-shaped forging ultrasonic detection probe of the utility model is shown, which comprises the above-mentioned ring-shaped forging ultrasonic detection accessory and an ultrasonic detection probe 200.
[0045] In use, coupling agent 20 is applied on the surface of the forging before ultrasonic detection, the ring-shaped forging ultrasonic detection accessory is installed on the ultrasonic detection probe 200, the gap is adjusted, and it is ensured that the coupling agent 20 can completely fill the gap and form a coupling agent protective layer during detection, so as to avoid direct contact between the ultrasonic detection probe 200 and the surface of the ring-shaped forging 10.

When used for detecting the inner diameter or the outer diameter of the workpiece, the circular arc curvature of the contact surface 121 of the second end 120 of the annular forging ultrasonic detection assembly can be processed according to the diameter of the annular forging 10, and during detection, only the ultrasonic detection assembly needs to be replaced, and the ultrasonic detection probe 200 does not directly contact the annular forging 10, that is, the end surface of the ultrasonic detection probe 200 does not rub against the surface of the annular forging 10 to consume the probe, and the friction consumption is only the position of the contact surface 121 of the ultrasonic detection assembly, when the gap reaches the limit, the connecting piece 300 can be loosened, and after the gap is adjusted again, it is fastened again, and it can be used for a very long time, and the processing cost of the annular forging ultrasonic detection assembly is far lower than the purchase price of the probe.
