Description

Technical Field

[0001] This utility model relates to the field of round bar inspection technology, specifically an online flaw detection device for the production of aluminum alloy round cast bars. Background Technology

[0002] Various defects may occur during the casting process of aluminum alloy round cast bars, such as cracks, inclusions, porosity, and material looseness. These defects can seriously affect the performance and quality of subsequent processed products. Therefore, quality inspection of aluminum alloy round cast bars is necessary.

On the other hand, some online flaw detection devices use simple ultrasonic testing methods. However, because the position and angle of the probe cannot be flexibly adjusted, it is difficult to achieve optimal detection results for round castings of different specifications, which can easily lead to missed defects.

[0050] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0051] refer to Figure 1-7 ,like Figure 1 As shown, an online flaw detection device for the production of aluminum alloy round casting rods includes a front section of screw conveyor 1, a rear section of screw conveyor 2, a middle section of screw conveyor 3, a detection component 4, a position sensor (not shown in the figure), and an encoder (not shown in the figure). The front section 1 of the screw conveyor is connected to the feeding mechanism (not shown in the figure), which can smoothly receive the aluminum alloy round casting rods conveyed by the feeding mechanism, preparing for the subsequent inspection process. The rear section 2 of the screw conveyor is connected to the unloading mechanism (not shown in the figure), which can transport the round casting rods that have completed flaw detection to the unloading mechanism, realizing the smooth connection of the entire production process. The middle section 3 of the screw conveyor is located between the front section 1 and the rear section 2. The detection component 4, position sensor and encoder are all located in the middle section 3 of the screw conveyor. The detection component 4, position sensor and encoder are all electrically connected. The detection component 4 can perform flaw detection on the round casting rod. The position sensor can sense the position information of the round casting rod in the middle section 3 of the screw conveyor in real time. The encoder can accurately record key data such as the spiral scanning distance of the round casting rod during the inspection process. Through the cooperation of the detection component 4, position sensor and encoder, the damage condition and location of the round casting rod can be obtained, thus obtaining comprehensive information about the round casting rod, providing an important basis for subsequent inspection and analysis.

[0052] In some embodiments, the front section 1, the rear section 2, and the middle section 3 of the screw conveyor each include a plurality of conveying components 5. Each of the multiple conveying components 5 is provided with a rotatable round casting rod. The conveying components 5 are provided with position sensors and encoders to accurately acquire various parameters of the round casting rod during the conveying process.

[0053] In some embodiments, the conveying assembly 5 includes a conveying frame 51, a rotating support 52, a main rotating roller 53, a driven rotating roller 54, and a drive motor 55. The conveying frame 51 provides a stable support structure for the entire conveying assembly. The rotating support 52 is mounted on the conveying frame 51. The main rotating roller 53 is arranged on one side of the rotating support 52, and the driven rotating roller 54 is arranged on the other side. The main rotating roller 53 and the driven rotating roller 54 are parallel to each other and are rolled together with the round casting rod. Both the main rotating roller 53 and the driven rotating roller 54 can be drum-shaped rotating rollers. The drive motor 55 is mounted on the conveying frame 51 and can be connected to the main rotating roller 53 through a transmission device such as a reducer. When the drive motor 55 is running, it drives the main rotating roller 53 to rotate, thereby using friction to drive the round casting rod to roll forward between the main rotating roller 53 and the driven rotating roller 54. To ensure the stability and smoothness of the rotation of the main rotating roller 53 and the driven rotating roller 54, the conveying assembly 5 is also equipped with multiple bearing seats 56. Both ends of the main rotating roller 53 and the driven rotating roller 54 are connected to the rotating support seat 52 through the bearing seats 56.

[0054] In some embodiments, the conveying assembly 5 further includes a plurality of bearing seats 56, and both ends of the main rotating roller 53 and the secondary rotating roller 54 are connected to the rotating support seat 52 through the bearing seats 56. By utilizing the low friction characteristics of the bearings, the resistance during rotation is reduced, thereby improving the stability of the round casting rod conveying.

[0055] In some embodiments, the detection assembly 4 includes a small core detection structure 6, an external detection structure 7, and a large core detection structure 8. The small core detection structure 6 is located on the side of the middle section 3 of the screw conveyor near the front section 1, and is mainly used to detect core defects in small-sized round cast bars. The external detection structure 7 is located on the side of the middle section 3 of the screw conveyor near the rear section 2, and is responsible for detecting external defects in the round cast bars. The large core detection structure 8 is located between the small core detection structure 6 and the external detection structure 7, and is specifically used to detect core defects in large-sized round cast bars. Furthermore, conveying assemblies 5 are provided between the small core detection structure 6 and the large core detection structure 8, and between the external detection structure 7 and the large core detection structure 8, to ensure smooth conveying of the round cast bars between different detection structures.

[0056] In some embodiments, the small core detection structure 6, the large core detection structure 8, and the external detection structure 7 have similar structures, all including a fixed base 61, a water tank 62, a lifting component 63, two support wheel sets 64, and a probe adjustment component 65. The water tank 62 is fitted onto the fixed base 61 and is used to accommodate the ultrasonic probe and coupling water. The lifting component 63 is located between the fixed base 61 and the bottom surface of the water tank 62 and is used to adjust the height of the water tank 62, facilitating flaw detection of round cast rods of different specifications according to different detection requirements. The water tank 62 can be made of 304 stainless steel, which contains a certain proportion of alloying elements such as chromium and nickel, forming a dense oxide film on the surface. This effectively resists corrosion from water and other chemicals, ensuring the reliability of the water tank 62 during long-term use. The water tank 62 can be connected to an external water tank via a pipeline. The external water tank can collect and filter the coupling water, automatically replenish and overflow, and can be cleaned and drained through a drain outlet. This is prior art and will not be described in detail here. Two support wheel sets 64 are symmetrically arranged on both sides of the water tank 62. The support wheel sets 64 are rolledly connected to the round casting rod, which can support the round casting rod, stabilize the position of the round casting rod, and ensure the accuracy of the detection process. The probe adjustment component 65 is located inside the water tank 62 and is used to adjust the position and angle of the ultrasonic probe to achieve accurate detection.

[0057] In some embodiments, the small core detection structure 6 is equipped with a small core probe assembly 66, which is mounted on the probe adjustment component 65; the large core detection structure 8 is equipped with a large core probe assembly 81, which is also mounted on the probe adjustment component 65; the external probe assembly 71 of the external detection structure 7 is also mounted on the probe adjustment component 65. A local water immersion ultrasonic testing method is used, employing pulse-echo ultrasonic waves to detect internal and surface defects in the round cast rod. The probe adjustment component 65 allows for flexible adjustment of the probe angle and position according to the specifications of the round cast rod and the testing requirements, achieving optimal testing results. The small core probe group 66, the large core probe group 81, and the external probe group 71 can all be in pairs, symmetrically arranged on both sides of the probe adjustment component 65. The small core probe group 66 and the large core probe group 81 each include six water immersion probes. Olympus (original imported) dedicated water immersion probes can be used for optimal results. The ultrasonic longitudinal waves emitted by the water immersion probes are incident along the diameter direction of the round cast rod to achieve radial longitudinal wave flaw detection, checking for internal defects such as cracks, through cracks, inclusions, porosity, and material looseness. The external probe group 71 also includes six water immersion probes, using Olympus (original imported) dedicated water immersion probes for optimal results. The ultrasonic longitudinal waves emitted by the water immersion probes are incident at a certain angle to achieve radial transverse wave flaw detection, checking for near-surface and surface defects such as cracks, inclusions, and porosity. By combining longitudinal wave detection and transverse wave detection, blind spots in the round cast rod detection can be avoided, achieving 100% inspection of the round cast rod.

[0058] In some embodiments, the probe adjustment component 65 includes a mounting block 651, a first rotating rod 652, a second rotating rod 653, a first adjusting rod 654, a first moving block 655, a second adjusting rod 656, a second moving block 657, and an adjusting plate 658. The mounting block 651 is firmly fixed to the bottom wall of the water tank 62, providing a stable mounting base for other components. The first rotating rod 652 and the second rotating rod 653 are arranged laterally and rotatably within the mounting block 651. The first rotating rod 652 and the second rotating rod 653 are parallel to each other, and a small core probe group 66, a large core probe group 81, or an external probe group 71 are mounted on both the first rotating rod 652 and the second rotating rod 653. The first adjusting rod 654 and the second adjusting rod 656 are arranged longitudinally and rotatably on the mounting block 651. The first moving block 655 is sleeved on the first adjusting rod 654, and the first moving block 655 and the first adjusting rod 654 are screwed together. The second moving block 657 is sleeved on the second adjusting rod 656, and is screwed together with the second adjusting rod 656. The top of the adjusting plate 658 is fixedly connected to the first rotating rod 652 or the second rotating rod 653, and the bottom is hinged to the side of the first moving block 655 or the second moving block 657. When the first adjusting rod 654 and the second adjusting rod 656 are rotated, the first moving block 655 and the second moving block 657 will move axially on the adjusting rod due to the action of the threads. This axial movement is converted into the rotation of the first rotating rod 652 or the second rotating rod 653 by the adjusting plate 658, thereby realizing the precise adjustment of the probe angle.

[0059] In some embodiments, to ensure the stability of the probe after adjustment, the probe adjustment component 65 is also provided with a locking component (not shown in the figure). The locking component is installed between the mounting block 651 and the first adjusting rod 654 or the second adjusting rod 656. When the probe is adjusted to a suitable angle, tightening the locking component increases the friction between the first adjusting rod 654 or the second adjusting rod 656 and the mounting block 651, fixing the first adjusting rod 654 or the second adjusting rod 656 in its current position and preventing it from rotating due to vibration or other factors during the detection process. This ensures the stability of the probe angle and thus the accuracy of the detection results. The locking component can be a locking pin or other fixing structure, which is prior art and will not be described in detail here.

[0060] In some embodiments, because the flat-bottomed hole being inspected is small, the two small core probe groups 66 and the two large core probe groups 81 are staggered to prevent small defects from being missed. This staggered arrangement allows for inspection of the core of the round casting rod from different angles, more comprehensively capturing defect information and thus improving the accuracy and reliability of the inspection.

[0061] In some embodiments, a control system is also included. The control system is electrically connected to the conveying assembly 5, the small core detection structure 6, the large core detection structure 8, the external detection structure 7, the position sensor, and the encoder. The control system can transmit the information of the round casting rod obtained by the small core detection structure 6, the large core detection structure 8, the external detection structure 7, the position sensor, and the encoder to the control system in real time. Based on this data, the control system can accurately analyze the operating status of the round casting rod and the specific location of defects, thereby obtaining the flaw detection results of the round casting rod.

[0062] The specific working principle is as follows:

[0063] During the testing process, the external probe assembly 71 is first adjusted to a suitable angle according to the specifications of the round cast rod. Then, the feeding system moves the round cast rod horizontally to the front section 1 of the screw conveyor, and the drive motor 55 starts to drive the round cast rod forward in a screw conveyor. At the same time, the water supply system starts to provide coupling water for the ultrasonic probe. During the screw conveyor process, the round cast rod passes through the small core detection structure 6, the large core detection structure 8, and the external detection structure 7 in sequence.

[0064] When the round casting rod is a small round rod, the small core detection structure 6 and the external detection structure 7 are activated.

[0065] The lifting component 63 in the small core detection structure 6 pushes the water tank 62 of the small core detection structure 6 to rise, and the lifting component 63 in the external detection structure 7 pushes the water tank 62 of the external detection structure 7 to rise.

[0066] When the round casting rod is conveyed to the water tank 62 in the small core detection structure 6, the round casting rod comes into contact with the coupling water in the water tank 62, and at the same time, the small core probe group 66 detects defects in the core area of ​​the round casting rod. The encoder records the spiral scanning distance of the round casting rod, and the position sensor records information such as the position and running time of the round casting rod.

[0067] When the round casting rod is conveyed to the water tank 62 in the external detection structure 7, the round casting rod comes into contact with the coupling water in the water tank 62, and at the same time, the external probe group 71 detects defects in the external area of ​​the round casting rod. The encoder records the spiral scanning distance of the round casting rod, and the position sensor records information such as the position and running time of the round casting rod.

[0068] When the round casting bar is a large round bar, the external inspection structure 7 and the large core inspection structure 8 are activated. The lifting component 63 in the large core inspection structure 8 pushes the water tank 62 of the large core inspection structure 8 to rise, and the lifting component 63 in the external inspection structure 7 pushes the water tank 62 of the external inspection structure 7 to rise. The flaw detection process is similar to the above process and will not be described in detail here.

[0069] After flaw detection, the round casting rod enters the rear section 2 of the screw conveyor from the middle section 3, and then enters the feeding mechanism through the conveying component 5, thus completing the online flaw detection of the round casting rod.

[0070] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
