Description

A flaw detection device for aluminum alloy plates Technical Field

[0001] This invention relates to the field of aluminum alloy sheet inspection technology, and in particular to a flaw detection device for aluminum alloy sheets. Background Technology

[0002] In modern industry, aluminum alloy sheets are widely used in aerospace, automotive manufacturing, and building decoration due to their excellent properties such as light weight, high strength, and corrosion resistance. However, during the production and processing of aluminum alloy sheets, defects such as porosity, inclusions, and cracks may occur due to factors such as casting, rolling, and heat treatment. These defects can seriously affect the mechanical properties and safety of aluminum alloy sheets. Therefore, it is essential to perform flaw detection on aluminum alloy sheets, and thus, a flaw detection device for aluminum alloy sheets is designed.

[0003] For example, patent CN112255254B discloses an automated aluminum alloy wheel hub flaw detection device, including a base plate and a cover fixed to the base plate. The cover has an inlet and an outlet. A conveying unit passing through the inlet and outlet is installed on the base plate. Two gripping units and two detection units are also installed inside the cover. The gripping units can grip the wheel hub at the conveying unit and place it at the detection unit. The detection units can perform flaw detection on the wheel hub.

[0004] However, the aforementioned patents are difficult to flexibly adjust to adapt to aluminum alloy plates of different thicknesses and widths, and cannot meet the feeding requirements of aluminum alloy plates of different specifications, making it difficult to meet diverse usage scenarios. At the same time, the positioning structure of the existing devices is simple and cannot automatically adjust the positioning according to the size of the plate.

Four linear bearings 623 are installed on the seat 62, and four guide rods 6221 move up and down within the four linear bearings 623 respectively. Their function is as follows: the fourth motor 641 serves as a power source, driving the connecting belt 66 to rotate, which in turn drives the transverse moving seat 62 to move left and right along the second horizontal plate 61, realizing the lateral adjustment of the plate position. The tensioning seat 65 and tensioning bolt 651 are screwed onto the second motor seat 64, which can adjust the tension of the connecting belt 66, ensuring the stable operation of the connecting belt 66 during transmission and avoiding damage. To prevent slippage and ensure the accuracy and reliability of the movement of the transverse support 62, the third hydraulic rod 621 at the lower end of the transverse support 62 can drive the support plate 622 to move up and down through the extension and retraction of the piston rod, realizing the lifting and lowering operation of the aluminum alloy sheet, making it convenient to place the sheet in the designated position. The four guide rods 6221 at the lower end of the support plate 622 cooperate with the four linear bearings 623 on the transverse support 62 to provide guidance and support for the up and down movement of the support plate 622, ensuring that the lifting and lowering process of the support plate 622 is smooth and avoiding shaking, thereby accurately placing the aluminum alloy sheet.

Two round rods 7321 are fixed between seat 731 and seat 732. A detection seat 733 is movable on the two round rods 7321. The upper end of the detection seat 733 is fixedly connected to the second drive belt 7323. A flaw detector 734 is mounted on the detection seat 733. The function of the flaw detector 734 is as follows: Motor 712 is mounted on a mounting seat 711 near the front bottom rod 71 of the top frame 8, and is connected to the connecting rod 723 via a belt. Then, the drive shaft 721 rotates, driving the first drive belt 722 to run, thereby enabling the moving rod 73 to slide back and forth on the seat plate 72. This allows the flaw detector 734 to move in the front and back direction of the plate, expanding the flaw detection coverage. The sixth motor 7322 drives the second drive belt 7323 to run, causing the detection seat 733 to move left and right on the round rod 7321, enabling the flaw detector 734 to move flexibly in multiple dimensions. This allows for comprehensive and thorough flaw detection of the aluminum alloy plate, ensuring the accuracy and reliability of the flaw detection results and improving the quality and efficiency of flaw detection work on aluminum alloy plates.

[0047] The working principle of this invention is as follows: Starting the first motor 234, power is transmitted to the right roller of the frame 23 after being changed through the gearbox 233, driving the conveyor belt 24 to start conveying aluminum alloy sheets. Operating the hand crank 211 rotates the screw of the lead screw jack 21, causing all four lead screw jacks 21 to operate synchronously via the transmission box 22. The height of the frame 23 is adjusted via the support rod 212 to accommodate different sheet specifications. Simultaneously, the first hydraulic rod 254 pushes the support arm 256 on the movable seat 255 near the right side of the positioning frame 25, causing the movable seat 255 to slide within the rail frame 252. The intermediate wheel 2531 meshes with the toothed plate 2552, driving the movable seats 255 on both sides to move synchronously, allowing the positioning roller 2554 to accurately position the sheet material, contacting the roller 255. 1. Ensure the movable seat 255 slides smoothly to prevent the plate from shifting. After the plate is conveyed to the designated position, start the second motor 323. The pulley on its output shaft drives the pulley at the lower end of the threaded rod 321 to rotate via a belt. The threaded rod 321 rotates accordingly. Since the threaded rod 321 is threadedly engaged with the threaded hole on the lifting frame 33, the lifting frame 33 slides stably and precisely up and down along the rail plate 32, lifting the plate to a suitable height for subsequent transfer processes. Start the third motor 52, driving the transmission rod 53 to rotate. This drives the first wheel 513, the second wheel 512, the third wheel 511 on the first horizontal plate 51, and the pulley of the transmission rod 53 itself to rotate synchronously, causing the transmission belt 515 to move. This, in turn, enables the movable plate 54 to move left and right on the slide rail. The slotted groove on plate 514, in conjunction with tensioning wheel 5141, allows for adjustment of the tension of transmission belt 515, ensuring stable transmission. Through the cooperation of hydraulic rod 541 and sliding plate 542, the position of support rod 543 can be flexibly adjusted, enabling the transfer and placement of aluminum alloy plates. This meets the efficient transfer requirements of plates between different workstations of the flaw detection device. Motor 641 operates, and the pulley on its output shaft drives the pulley on wheel seat 63 to rotate via connecting belt 66, causing the transverse sliding seat 62 to slide left and right on the two horizontal plates 61. Tightening the tension bolt 651 on tensioning seat 65 adjusts the tension of connecting belt 66, ensuring precise movement of transverse sliding seat 62. Hydraulic rod 621 at the lower end of transverse sliding seat 62 extends and retracts, driving the support plate 622 to rise and fall. The four guide rods 6221 at the lower end of 622 cooperate with the four linear bearings 623 on the transverse sliding seat 62 to ensure the smooth lifting and lowering of the pallet 622 and accurately move the plate to the designated position. The fifth motor 712 is installed on the mounting base 711 near the front bottom rod 71 of the top frame 8. It is connected to the connecting rod 723 via a belt, driving the shaft 721 to rotate, which drives the first drive belt 722 to run, thereby realizing the forward and backward sliding of the moving rod 73 on the seat plate 72. This allows the flaw detector 734 to move in the forward and backward direction of the plate, expanding the flaw detection coverage. The sixth motor 7322 drives the second drive belt 7323 to run, causing the detection seat 733 to move left and right on the round rod 7321, realizing the flexible movement of the flaw detector 734 in multiple dimensions.A comprehensive, thorough flaw detection process is performed on the aluminum alloy sheets to ensure accurate and reliable results.
