Description

Technical Field

[0001] This utility model relates to the field of flaw detection equipment, specifically to an ultrasonic flaw detection device for target materials. Background Technology

[0002] In the field of target manufacturing, the quality inspection of cylindrical targets typically involves two key steps: ultrasonic testing (UT) and vacuum sealing. Currently, in the ultrasonic testing (UT) and vacuum treatment process of cylindrical targets, the target must first be individually sealed and vacuumed before being transferred to UT equipment for water immersion testing. Traditional target sealing fixtures are single-channel and only support a single pump type. If it is necessary to switch from Roots pump pre-evacuation to molecular pump fine evacuation, the pipeline must be disassembled and the fixture replaced, resulting in cumbersome operation procedures and low target processing efficiency.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figures 1 to 4 As shown, the ultrasonic flaw detection equipment for target material 100 of this utility model includes a frame 1 with a water immersion tank 11, a detection component 2, a rotating component 3, and a sealing fixture 4.

[0017] See Figure 1 , Figure 2 The water immersion tank 11 of the frame 1 is used to place the cylindrical target 100 to be inspected. The water immersion tank 11 is filled with circulating water of a certain depth. The detection component 2 includes at least an ultrasonic probe 21. The ultrasonic probe 21 can emit high-frequency sound waves into the target 100. When the sound waves encounter defects or interfaces, some of the energy will be reflected back to the ultrasonic probe 21 and converted into an electrical signal output. The ultrasonic probe 21 is configured to move along the X-axis, Y-axis or Z-axis to achieve all-round inspection of the target 100 and to be compatible with targets 100 of different sizes. The rotating component 3 is located in the water immersion tank 11 of the frame 1. It is used to support the cylindrical target 100 and can control the circumferential rotation of the cylindrical target 100.

[0018] See Figure 3 , Figure 4 The sealing fixture 4 includes a fixture body 41, a three-way pipe 42, a first switch 43, and a second switch 44. The fixture body 41 has an air hole extending through it along its axis. The three-way pipe 42 has a main pipe 421, a first branch 422, and a second branch 423. The main pipe 421 is inserted into the air hole of the fixture body 41. The first switch 43 is located on the first branch 422 to control the opening and closing of its internal passage. The second switch 44 is located on the second branch 423 to control the opening and closing of its internal passage.

[0019] Specifically, when performing flaw detection on the cylindrical target 100, firstly, the fixture body 41 is bolted to the end of the target 100 to seal the inner cavity of the target 100. Then, the target 100 is hoisted and placed on the rotating assembly 3. The first branch 422 is externally connected to a Roots vacuum pump 51 (medium-low vacuum pump), and the first switch 43 is turned on and the second switch 44 is turned off. The Roots vacuum pump 51 is used to evacuate the target 100. After completion, the first switch 43 is turned off. The rotating assembly 3 controls the rotation of the target 100 and moves the ultrasonic probe 21 to a predetermined position, thereby completing the flaw detection of the target 100. After surface flaw detection, the target 100 is removed from the water immersion tank 11 of the frame 1. The second branch 423 of the three-way pipe 42 is connected to the diffusion molecular pump 52 (ultra-high vacuum pump) through an external pipeline. Then, the second switch 44 is turned on, and the diffusion molecular pump 52 continues to evacuate the cavity of the target 100 to obtain a higher vacuum degree, meeting the ultra-high vacuum environment requirements of subsequent processes (such as welding, encapsulation, helium detection). This setup saves the time of the diffusion molecular pump 52 evacuating the target 100, greatly reducing the complexity and operation time, and improving the efficiency of vacuum evacuation. It should be noted that the physical characteristics of the Roots vacuum pump 51 and the diffusion molecular pump 52 mean that they cannot share the same evacuation pipeline when evacuating. Therefore, two sets of gas paths are required to meet the needs of different vacuum degrees in the cavity of the target 100.

[0020] In one or more embodiments, the first branch 422 of the three-way pipe 42 is provided with a first rotary joint 61, and the second branch 423 of the three-way pipe 42 is provided with a second rotary joint 62. The first rotary joint 61 and the second rotary joint 62 can be of the RJH series rotary joint type; the gas pipe of the Roots vacuum pump 51 is connected to the fixture body 41 through the first rotary joint 61, the purpose of which is to allow the target 100 to rotate during UT testing to avoid entanglement of the gas pipe.

[0021] In one or more embodiments, the detection component 2 further includes a three-axis linear module 22 mounted on the frame 1, and the ultrasonic probe 21 is driven by the three-axis linear module 22 to move along the X-axis, Y-axis or Z-axis direction.

[0022] See Figure 1 , Figure 2 The three-axis linear module 22 includes an X-axis linear module, a Y-axis linear module, and a Z-axis linear module. The Y-axis and Z-axis linear modules are driven by the X-axis linear module along the X-axis direction, and the Z-axis linear module is controlled by the Y-axis linear module along the Y-axis direction. The ultrasonic probe 21 is mounted on the Z-axis linear module. This configuration allows the ultrasonic probe 21 to move along the X, Y, or Z axes, enabling it to adapt to the flaw detection of target materials 100 of different sizes.

[0023] In one or more embodiments, the rotating assembly 3 includes a first roller 31 and a second roller 32, a first driving device for controlling the rotation of the first roller 31 or the second roller 32, and a pushing structure for pressing against the end of the target material 100 and the fixture body 41.

[0024] See Figure 2 The first roller 31 and the second roller 32 are rotatably installed on the bottom surface inside the water immersion tank 11. The first driving device can be a servo motor. The first driving device can control either the first roller 31 or the second roller 32 to rotate. The pushing structure can press against one end of the target material 100 and the fixture body 41, so that the target material 100 does not change position when rotating, thereby improving the stability of the test results of the target material 100.

[0025] In one or more embodiments, the pushing structure includes a first pushing member and a second pushing member disposed within the immersion tank 11. The first pushing member and / or the second pushing member are configured to move along the axial direction of the first roller 31. Both the first pushing member and the second pushing member can be pushing wheels. A telescopic cylinder can be provided on the frame 1 to control the movement of the first pushing member or the second pushing member toward the target 100 to fix the position of the target 100 along the axial direction.

[0026] In one or more embodiments, a water circulation assembly is also provided on the frame 1. The water circulation assembly is used to provide circulating water to the water immersion pool 11. The water circulation assembly includes a water tank 71, a circulation pump 72, a first water pipe and a second water pipe. The outlet of the circulation pump 72 is connected to the water immersion pool 11 through the first water pipe, the inlet of the circulation pump 72 is connected to the water tank 71 through the second water pipe, and the water immersion pool 11 is connected to the water tank 71 through a third water pipe.

[0027] See Figure 1 , Figure 2 The third water pipe is an overflow pipe. When the circulating pump 72 draws water from the water tank 71 to the water tank 71 and reaches a predetermined height, the water inside the water tank 71 overflows into the water tank 71 through the third water pipe, thus circulating the water within the water tank 71 and the immersion pool 11. In other possible ways, a filter device can be added between the water tank 71 and the circulating pump 72 to reduce impurities in the water flow and improve the flaw detection accuracy of the target material 100.

[0028] In one or more embodiments, the inner wall of the pore is provided with an annular sealing groove, and a sealing ring is embedded in the annular sealing groove. The outer wall of the main pipe 421 of the three-way pipe 42 is interference-fitted with the sealing ring to improve the sealing performance after the inner cavity of the target material 100 is blocked.

[0029] In one or more embodiments, the surface of the water immersion tank 11 is coated with a polytetrafluoroethylene (PTFE) coating. The PTFE coating has a certain anti-corrosion effect, which can reduce the possibility of rust formation on the surface of the water immersion tank 11, thereby reducing the possibility of contamination of the target material 100 during the flaw detection process.

[0030] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
