Description

Technical Field

[0001] This invention relates to the field of casting flaw detection technology, and more specifically, to a casting flaw detection and testing device. Background Technology

[0002] Large cylindrical ingots are the most common form of casting in the metal casting industry. After casting, large cylindrical ingots require ultrasonic testing. Ultrasonic testing can detect internal defects in the ingot, such as porosity, inclusions, and cracks, thereby ensuring the quality of the ingot. During ultrasonic testing of large cylindrical ingots, a coupling agent is first applied to the surface of the ingot along the trajectory of the testing head. After application, the testing head is controlled to move linearly along the outer surface of the ingot. After testing, any remaining coupling agent on the ingot surface is wiped off. However, current ultrasonic testing methods still... There are certain drawbacks: First, in the inspection of large cylindrical ingots, if a water-based coupling agent is used, the overall inspection time is long due to the large diameter and length of the ingot. The coupling agent in the later areas of the inspection may dry out before the inspection head arrives, resulting in a large number of false defect signals and affecting the comprehensiveness and accuracy of the inspection results. On the other hand, if an oil-based coupling agent is used, although it can stay on the surface of the ingot for a long time and is not easily volatilized, it needs to be cleaned with a special cleaning agent after the inspection, and the cleaning is relatively difficult.

[0003] Secondly, the entire flaw detection trajectory is coated with coupling agent before flaw detection and the residual coupling agent is cleaned uniformly after flaw detection. This results in a longer flaw detection cycle for the entire large cylindrical ingot. Furthermore, as the number of inspections increases, the time lost will gradually accumulate, and the impact on production efficiency and cost will gradually increase.

[0004] Furthermore, due to the large diameter of large cylindrical ingots, a single flaw detection path can usually only cover a part of the area, which can easily miss some defects hidden at different angles or depths, thus making it necessary to improve the comprehensiveness and accuracy of the flaw detection results. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a casting flaw detection device, including a base and a fixed rotating part fixedly installed on the top of the base for placing the ingot. A gantry frame is slidably installed on the top of the base. A linear moving part with an integrated working part is provided above the fixed rotating part. A driving component for driving the linear moving part to rise and fall is provided on the top of the gantry frame. The integrated working part includes a wiping and rubbing assembly and a reversing assembly for controlling the reversing of the wiping and rubbing assembly.

[0006] The wiping and probing assembly includes a fixed shaft fixedly connected to the linear moving part and a rotating shaft rotatably mounted at the bottom of the fixed shaft. A reversing plate is fixedly mounted at the bottom of the rotating shaft, and a coupling agent nozzle, a flaw detector head, and a wiping cloth are sequentially mounted on the bottom of the reversing plate from left to right.

[0007] Furthermore, the reversing assembly includes a helical groove formed on the outside of the rotating shaft and a reversing sleeve slidably sleeved on the outside of the rotating shaft. A spring telescopic rod one is slidably connected in the helical groove, and a spring telescopic rod two, which is symmetrical to the spring telescopic rod one, is fixedly installed on the rear side of the reversing sleeve. The fixed section of the spring telescopic rod one is fixedly inserted through the reversing sleeve.

[0008] Furthermore, the output end of the drive component slides through the top of the gantry and is fixedly mounted with a drive plate. The front and rear sides of the drive plate are fixedly mounted with fixed plates by several C-shaped rods. The two fixed plates are symmetrical front and rear. A reversing groove is opened on the side of the fixed plate near the rotating shaft. The telescopic sections of spring telescopic rod one and spring telescopic rod two are slidably connected in the front and rear reversing grooves respectively. The reversing groove is a parallelogram and a check groove is opened at each of the two acute angles of the reversing groove. The groove depth of the check groove is greater than the groove depth of the reversing groove, and a transition arc surface is opened at the connection between the check groove and the horizontal section of the reversing groove.

[0009] Furthermore, the fixed rotation part includes a plurality of support components arranged at equal intervals, a clamping component disposed on the support components, and a control component for controlling the rotation of the ingot. The support components include a mounting plate fixedly installed on the top of the base and a support plate symmetrically installed on the top of the mounting plate. A plurality of rollers for supporting the ingot are rotatably installed on the top of the support plate. The control component is provided with an indicator for controlling the rotation angle of the ingot so that the ingot rotates at a fixed angle.

[0010] Furthermore, the clamping assembly includes two hinged plates rotatably mounted between two support plates and symmetrically arranged front and back. The rotation point of the hinged plates is located above their center. A clamping plate is rotatably mounted on the top of the hinged plates. The two clamping plates are symmetrical to each other and are used to clamp and fix the ingot. A push rod is fixedly mounted on the bottom end of the hinged plates. The push rod is located below the rotation point of the hinged plates. A push plate is slidably mounted on the outer side of the two opposing push rods. The push plate has two push grooves symmetrically arranged front and back. The push grooves are inclined. The two push grooves symmetrically arranged front and back form a figure-eight structure with the small diameter end facing upward. The two push rods are slidably connected in the two push grooves respectively.

[0011] Furthermore, the control assembly includes control rods fixedly installed at the bottom of the push plate, control slots are provided on the support plate, a control plate is slidably installed in several control slots, the bottom ends of the three control rods are fixedly connected to the control plate, and two symmetrical cylinders are fixedly installed on the top of the base, with the output ends of the cylinders fixedly connected to the control plate.

[0012] Furthermore, the linear moving part includes a linear slide rail fixedly mounted on the bottom of the drive plate and an electric slider slidably mounted on the bottom of the linear slide rail, with a fixed shaft fixedly mounted on the bottom of the electric slider.

[0013] Furthermore, a limiting rod that slides through the gantry is fixedly installed on the top of the drive plate, and a limiting circular plate is fixedly installed on the top of the limiting rod.

[0014] Furthermore, the top of the base is provided with two symmetrical sliding grooves, and the bottom left and right sides of the gantry frame are slidably installed in the two sliding grooves respectively.

[0015] The beneficial effects of the present invention are as follows: 1. The integrated operation unit of the present invention continuously completes the operations of applying coupling agent, conducting immediate flaw detection and wiping coupling agent on the same path, ensuring a more stable contact state between the flaw detection head and the surface of the ingot. It eliminates the need to apply coupling agent separately before flaw detection and to wipe off the coupling agent uniformly after flaw detection, thereby greatly improving the accuracy and consistency of flaw detection results and significantly improving overall efficiency.

[0016] 2. In this invention, the flaw detection head and the couplant nozzle move synchronously. The couplant is sprayed onto the surface of the ingot before the flaw detection head arrives. Instead of spraying all the couplant in the flaw detection area at once, the water-based couplant will not dry out in a short time, even if the flaw detection time is long or in a high-temperature and well-ventilated environment. It can still maintain good coupling performance, thereby greatly improving the comprehensiveness and accuracy of the flaw detection results.

[0017] 3. By setting the rotation and reversal directions of the coupling agent nozzle, the flaw detection head, and the wiping cloth, this invention ensures that the coupling agent nozzle, the flaw detection head, and the wiping cloth all remain operational during the left and right movement of the electric slider. The coupling agent nozzle always applies coupling agent in the direction of movement and is the first to work, thereby enabling continuous multiple flaw detection tests on the current flaw detection area and improving the accuracy of the test results.

[0018] 4. In each flaw detection process, the electric slider moves along the linear slide rail, and the coupling agent nozzle accurately sprays coupling agent according to the movement path of the flaw detection head. The flaw detection head follows closely to perform detection, and then the wiping cloth immediately cleans up the residual coupling agent, ensuring that each flaw detection position undergoes the same processing procedure, thereby greatly improving the accuracy and consistency of flaw detection results.

[0028] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0029] See Figure 1 , Figure 3 , Figure 4 and Figure 8 A casting flaw detection device includes a base 1 and a fixed-rotation part 2 fixedly mounted on the top of the base 1 for placing an ingot. The fixed-rotation part 2 includes a plurality of support components 201 arranged at equal intervals, clamping components 202 disposed on the support components 201, and a control component for controlling the rotation of the ingot. A gantry frame 4 is slidably mounted on the top of the base 1, and a drive component 5 is fixedly mounted on the top of the gantry frame 4. The output end of the drive component 5 slides through the top of the gantry frame 4 and is fixedly mounted on a drive plate 6. An integrated working part 8 is provided at the bottom of the drive plate 6 through a linear moving part 7. The integrated working part 8 includes a wiping and probing component 801 and a reversing component 802 for controlling the rotation direction of the wiping and probing component 801. It should be noted that the drive component 5 can be an existing hydraulic cylinder or a pneumatic cylinder.

[0030] See Figure 1 and Figure 8 A limiting rod 9, which slides through the gantry frame 4, is fixedly installed on the top of the drive plate 6. A limiting circular plate is fixedly installed on the top of the limiting rod 9. Two symmetrical sliding grooves 3 are opened on the top of the base 1. The bottom left and right sides of the gantry frame 4 are slidably installed in the two sliding grooves 3 respectively. A driving component (not shown in the figure) for driving the gantry frame 4 to move back and forth along the sliding groove 3 is provided in the sliding groove 3. It should be noted that the driving component can be a conventional driving component such as an electric slider or a lead screw mechanism.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 8 The supporting assembly 201 includes a mounting plate 2011 fixedly installed on the top of the base 1 and support plates 2012 symmetrically installed on the top of the mounting plate 2011. Several rollers 2013 for supporting ingots are rotatably mounted on the top of the support plates 2012. The control mechanism consists of an electric push rod with a through bearing installed on the vertical section of the gantry frame 4 and an electric three-jaw chuck mounted on the pushing end of the electric push rod.

[0032] It should be noted that the pushing end of the electric actuator is connected to the existing drive source to enable the electric actuator to drive the three-jaw chuck to rotate; in addition, two electric actuators can also be connected to the same drive source through a pulley mechanism. The position arrangement of the pulley mechanism and the drive source can be adapted according to the position of other components of the equipment, provided that it does not obstruct the operation of other components.

[0033] See Figure 1 , Figure 2 and Figure 3The clamping assembly 202 includes two hinged plates 2021 rotatably mounted between two support plates 2012 and symmetrically arranged front and back. A clamping plate 2022 is rotatably mounted on the top of the hinged plate 2021. The two clamping plates 2022 are symmetrical with each other and cooperate to clamp and fix the ingot. A push rod 2025 is fixedly mounted on the bottom end of the hinged plate 2021. The rotation point of the hinged plate 2021 is located above the push rod 2025, and the rotation point of the hinged plate 2021 is located above its center. A push plate 2023 is slidably mounted on the outer side of the two opposing push rods 2025. The push plate 2023 has two push grooves 2024 symmetrically arranged front and back. The push grooves 2024 are inclined and form a small-diameter, upward-facing V-shaped structure. The push rods 2025 are slidably connected in the corresponding push grooves 2024.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 The control component 203 includes control rods 2032 fixedly installed at the bottom of the push plate 2023, control slots 2031 are provided on the support plate 2012, and a control plate 2033 is slidably installed in several control slots 2031. The bottom ends of the three control rods 2032 are all fixedly connected to the control plate 2033. Two symmetrical cylinders 2034 are fixedly installed on the top of the base 1, and the output end of the cylinders 2034 is fixedly connected to the control plate 2033.

[0035] In practical use, initially, the gantry 4 is located at the rearmost side of the slide 3 (the side furthest from the ingot) to avoid obstructing the hoisting and placement of the ingot (e.g., Figure 8 As shown, when it is necessary to detect whether there are defects inside the ingot, the ingot is lifted from the storage position by external hoisting equipment, and then the ingot is slowly moved and placed steadily on the roller 2013 on the top of the pallet 2012, ensuring that the ingot is in good contact with the roller 2013 and the center of gravity is stable. Then, the cylinder 2034 is activated, and the output end of the cylinder 2034 pushes the control plate 2033 upward, thereby driving the push plate 2023 upward through the control rod 2032, which in turn causes the push groove 2024 to squeeze the push rod 2025, driving the hinge plate 2021 to rotate closer to the ingot, and then driving the clamping plate 2022 to clamp and fix the ingot. After the ingot is fixed, the gantry 4 is driven to move forward along the slide 3 by the drive component, thereby driving the linear moving part 7 and the integrated working part 8 to move forward until the gantry 4 moves to the front of the slide 3, and the linear moving part 7 and the integrated working part 8 are exactly above the ingot.

[0036] When it is necessary to control the rotation of the ingot to adjust the flaw detection position, first control the output end of the cylinder 2034 to retract, driving the clamping plate 2022 to release the clamp on the ingot. Then, the electric push rod moves the electric three-jaw chuck toward the end of the ingot to a suitable position. Then the electric three-jaw chuck works to clamp the end of the ingot, but at this time the ingot is still supported by the support plate 2012 and the roller 2013. Then, the electric push rod is controlled to rotate through the corresponding existing drive source, and the ingot is driven to rotate through the three-jaw chuck to change to the next flaw detection position. After the switch is completed, the three-jaw chuck is reset by the electric push rod to avoid affecting subsequent inspections.

[0037] See Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 8 The wiping and probing assembly 801 includes a fixed shaft 8011 fixedly connected to the linear moving part 7 and a rotating shaft 8012 rotatably mounted at the bottom end of the fixed shaft 8011. A reversing plate 8013 is fixedly mounted at the bottom of the rotating shaft 8012. From left to right, a coupling agent nozzle 8014, a flaw detector head 8015, and a wiping cloth 8016 are fixedly mounted on the bottom of the reversing plate 8013. To improve the accuracy of each rotation angle of the ingot and ensure comprehensive flaw detection of the ingot, an indicator is set on the rotation control component to control the rotation angle of the ingot so that the ingot rotates at a fixed angle. The indicator includes a scale with angle lines set on the outer side of one of the vertical sections of the gantry frame 4. The scale is concentric with the corresponding electric push rod, and an indicator plate is set on the outer side of the fixed end of the electric push rod. The single rotation angle of the ingot is controlled by the indicator plate and the angle lines. The distribution angle of the angle lines basically matches the application range of the coupling agent nozzle 8014. When the electric push rod drives the ingot to rotate through the three-jaw chuck, the indicator plate rotates synchronously with the electric push rod. With the cooperation of the indicator plate and the angle line, the rotation angle of the ingot can be accurately controlled, avoiding missed areas and improving the effectiveness and quality of ingot inspection.

[0038] See Figure 4 , Figure 5 , Figure 6 and Figure 8 The linear moving part 7 includes a linear slide rail 701 fixedly installed at the bottom of the drive plate 6 and an electric slider 702 slidably installed at the bottom of the linear slide rail 701. The fixed shaft 8011 is fixedly installed at the bottom of the electric slider 702.

[0039] In practical use, after the gantry 4 moves the linear moving part 7 and the integrated working part 8 to directly above the ingot, the drive unit 5 is activated. The output end of the drive unit 5 pushes the drive plate 6 downward, thereby driving the electric slider 702 downward through the linear slide rail 701, and then driving the reversing plate 8013 downward until the coupling agent nozzle 8014, the flaw detector head 8015, and the wiping cloth 8016 are still a small gap from the ingot in the vertical direction. Then the output end of the drive unit 5 stops, and the electric slider 702 is first controlled to move to the right along the linear slide rail 701. When the coupling agent nozzle 8014 gradually moves above the ingot, the coupling agent nozzle 8014 connected to the existing coupling agent spraying equipment is controlled to spray coupling agent onto the surface of the ingot. When the flaw detector head 801... As the probe 8015 gradually moves above the ingot, the output of the control drive 5 is pushed downwards a short distance, causing the flaw detector 8015 to come into contact with the top of the ingot. Then, the electric slider 702 continues to move along the linear slide rail 701 to perform flaw detection. During the flaw detection process, the coupling agent nozzle 8014 continuously applies coupling agent to the surface of the ingot along the moving path of the flaw detector 8015. The flaw detector 8015 can pass through the coupling agent in time, and the coupling agent can fill the gap between the flaw detector 8015 and the surface of the ingot, thereby ensuring that the ultrasonic waves can propagate efficiently between the probe and the workpiece and reducing signal attenuation. After the flaw detector 8015 performs the detection, the wiping cloth 8016 immediately wipes away the residual coupling agent on the position that the flaw detector 8015 just detected, achieving the effect of wiping and probing in one step.

[0040] After a single flaw detection, the reversing plate 8013 is rotated 180° by the reversing assembly 802 to swap the positions of the coupling agent nozzle 8014 and the wiping cloth 8016. Then, the flaw detection is performed again to detect the same flaw location at least twice. After the detection, the ingot is rotated to switch the flaw detection position, and then the above flaw detection operation is repeated.

[0041] See Figure 4 , Figure 5 and Figure 6 The reversing assembly 802 includes a spiral groove 8022 formed on the outside of the rotating shaft 8012 and a reversing sleeve 8021 slidably sleeved on the outside of the rotating shaft 8012. A spring telescopic rod 8023 is slidably connected in the spiral groove 8022. A spring telescopic rod 8024, which is symmetrical to the spring telescopic rod 8023, is fixedly installed on the rear side of the reversing sleeve 8021. The fixed section of the spring telescopic rod 8023 passes through the reversing sleeve 8021.

[0042] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The drive plate 6 has a fixed plate 8026 fixedly installed on both the front and rear sides by a number of C-shaped rods 8025. The two fixed plates 8026 are symmetrical front and rear and located below the linear slide rail 701. The fixed plate 8026 has a reversing groove 8027 on the side near the rotating shaft 8012. The telescopic sections of the spring telescopic rod 1 8023 and the spring telescopic rod 2 8024 are slidably connected in the front and rear reversing grooves 8027 respectively. The reversing groove 8027 is parallelogram-shaped and has a check groove 8028 at each of the two acute angles. The groove depth of the check groove 8028 is greater than the groove depth of the reversing groove 8027, and a transition arc surface 8029 is provided at the connection between the check groove 8028 and the horizontal section of the reversing groove 8027.

[0043] In practical use, when the electric slider 702 drives the coupling agent nozzle 8014, the flaw detection head 8015, and the wiping cloth 8016 to move linearly along the linear slide rail 701 for the initial flaw detection of the ingot, the extension sections of the spring telescopic rod 1 8023 and spring telescopic rod 2 8024 first slide from the lower left check groove 8028 to the right, then pass through the transition arc surface 8029 and enter the lower horizontal section of the reversing groove 8027. As the flaw detection operation gradually progresses, when the spring telescopic rod 1 8023 and spring telescopic rod 2 8024 move to the right inclined section of the reversing groove 8027, the electric slider 702 continues to move, and the spring telescopic rod 1 8023 and spring telescopic rod 2 8024 will move along the reversing groove 802... When the right-inclined section of 7 moves upward, the spring telescopic rod 8023 and the spring telescopic rod 8024 will drive the reversing sleeve 8021 to move upward synchronously. At the same time, the fixed section of the spring telescopic rod 8023 cooperates with the spiral groove 8022 to drive the rotating shaft 8012 to rotate. When the spring telescopic rod 8023 and the spring telescopic rod 8024 enter the connection between the upper right check groove 8028 and the right-inclined section of the reversing groove 8027, they stop moving upward. At this time, the rotating shaft 8012 rotates 180°, thereby driving the reversing plate 8013 to rotate 180°, and then driving the coupling agent nozzle 8014, the flaw detector head 8015 and the wiping cloth 8016 to rotate 180°, changing direction to prepare for secondary flaw detection.

[0044] During secondary flaw detection, the electric slider 702 drives the coupling agent nozzle 8014, the flaw detection head 8015, and the wiping cloth 8016 to move linearly along the linear guide rail 701. The telescopic sections of spring telescopic rod one 8023 and spring telescopic rod two 8024 first slide from the upper right check groove 8028 to the left, and then enter the upper horizontal section of the reversing groove 8027 after passing the corresponding transition arc surface 8029. As the flaw detection operation progresses, when spring telescopic rod one 8023 and spring telescopic rod two 8024 move to the left inclined section of the reversing groove 8027, they will move downward along the left inclined section. As spring telescopic rod one 8023 and spring telescopic rod two 8024 move downward, the reversing sleeve 8021 moves downward synchronously. At the same time, the fixed section of spring telescopic rod one 8023... The spiral groove 8022 works in conjunction with the rotating shaft 8012 to rotate. When the first spring telescopic rod 8023 and the second spring telescopic rod 8024 enter the lower left check groove 8028, they stop moving. At this time, the rotating shaft 8012 rotates 180°, thereby driving the reversing plate 8013 to rotate 180°, which in turn drives the coupling agent nozzle 8014, the flaw detector head 8015, and the wiping cloth 8016 to rotate 180° to reverse their direction and reset. During the left and right movement of the electric slider 702, the coupling agent nozzle 8014, the flaw detector head 8015, and the wiping cloth 8016 all remain in operation. The coupling agent nozzle 8014 always applies coupling agent in the direction of movement and is the first to work. This allows for continuous multiple flaw detections of the current flaw detection area, improving the accuracy of the detection results.

[0045] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
