Description

Technical Field

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

[0002] Titanium and titanium alloy ingots are essential raw materials for the manufacturing of high-end equipment in aerospace, chemical, and shipbuilding industries. Their internal and surface quality directly affects the performance and safety of subsequently processed products. Therefore, comprehensive non-destructive testing of titanium ingots before shipment is an indispensable process. However, existing titanium ingot testing methods, especially optical or eddy current testing of surface defects (such as cracks, porosity, and inclusions), generally face the following technical bottlenecks: The detection environment is highly susceptible to interference, making it difficult to guarantee accuracy: Many surface defect detection technologies (such as machine vision and laser scanning) are very sensitive to ambient light. In bright workshop environments, the reflection of external light and glare can severely interfere with the signals received by the sensors, leading to missed detections, false detections, and poor reliability and consistency of the detection results.

[0003] Incomplete detection coverage with blind spots: Traditional methods often use fixed sensors to scan stationary or linearly moving titanium ingots. For cylindrical or nearly square titanium ingots, the top and sides can be detected well, but the bottom and the area in contact with the support surface often become blind spots, making it impossible to achieve true 360-degree coverage without dead angles.

[0004] Low testing efficiency and continuity: Most testing equipment requires manual loading and unloading or precise positioning of titanium ingots at the testing station, resulting in long testing cycles for single pieces and making it difficult to adapt to large-scale, continuous production. The testing process is often intermittent, affecting overall production efficiency.

[0005] There is a risk of damaging the workpiece surface: To achieve full-surface inspection, it is sometimes necessary to lift or flip the titanium ingot. During this process, fixtures or equipment parts may collide with the surface of the titanium ingot. In particular, protective doors or baffles of some inspection equipment may leave scratches on the smooth surface of the moving titanium ingot if they come into hard contact with it, causing secondary damage.

[0006] Insufficient automation and intelligence: The detection, conveying, and protection processes are often controlled independently with poor coordination. They cannot automatically adjust detection parameters or perform avoidance actions based on the real-time position of the titanium ingot, resulting in a low level of intelligent linkage throughout the entire process.

[0007] Therefore, developing a high-efficiency titanium ingot flaw detection device that can provide a stable detection environment, realize full-surface automatic scanning, support continuous operation, and intelligently protect the workpiece is of great significance for improving product quality control and production efficiency. Summary of the Invention

[0013] As a preferred embodiment of the present invention, the placement seat mechanism includes a plurality of mounting side plates fixed to the base, the mounting side plates being fixedly connected to the placement seat, and the placement seat being provided with vertical grooves and side grooves.

[0014] As a preferred embodiment of the present invention, the conveyor belt mechanism includes a second motor mounted on a placement seat, the output shaft of the second motor being fixedly connected to a first conveyor wheel, the first conveyor wheel being rotatably connected to the placement seat, the first conveyor wheel being driven to connect two conveyor belts, the conveyor belts being driven to connect a second conveyor wheel, and the second conveyor wheel being rotatably connected to the placement seat.

[0015] As a preferred embodiment of the present invention, the follower lever mechanism includes a first tension spring fixed on the placement seat, the first tension spring being fixedly connected to a follower block, the follower block being located on a vertical groove, the follower block being slidably connected to the placement seat, and a lever being provided on the follower block.

[0016] As a preferred embodiment of the present invention, the synchronous lever mechanism includes a third motor mounted on a follower block.

The gear shafts are fixedly connected to second gears, which mesh with each other. The gear shafts are fixedly connected to a multi-stage electric telescopic rod. A motor frame is mounted on the displacement block, and a fifth motor is fixedly connected to the motor frame. The output shaft of the fifth motor and one of the gear shafts are coaxially fixedly connected.

[0017] As a preferred embodiment of the present invention, the reset lever mechanism includes a second tension spring fixed to the bottom of the follower block. The end of the second tension spring away from the follower block is fixedly connected to a pull plate. The follower block is fixedly connected to a deflection frame seat.

[0018] The present invention has the following advantages: 1. This titanium ingot flaw detection device, through its integrated design, achieves significant improvements in detection accuracy, efficiency, and workpiece protection. Its core advantage lies in the detection chamber mechanism, which creates a closed, dark environment, effectively isolating the optical sensors from external stray light interference, thus providing ideal conditions for high-contrast, high-precision surface imaging or scanning. The internal rotating detection mechanism drives multiple flaw detection sensors to rotate uniformly around the titanium ingot's axis. Combined with the ingot's own axial movement, this forms a spiral scanning path, achieving truly comprehensive, blind-spot-free detection of the titanium ingot's cylindrical surface, completely eliminating blind spots inherent in traditional fixed scanning methods.

[0019] 2. This device achieves continuous and highly automated testing, significantly improving operational efficiency. The conveyor belt mechanism smoothly and continuously transports titanium ingots through the testing stations, eliminating the frequent start-stop and positioning time required in traditional methods. More importantly, its innovative highlight is the intelligent linkage lever system. The follow-up lever mechanism automatically senses and "attaches" to the moving end of the titanium ingot, moving synchronously; the synchronous lever mechanism precisely controls the multi-stage electric telescopic rod to drive the lever action based on the real-time position of the titanium ingot, opening the testing chamber cover before the titanium ingot arrives and closing it promptly after the ingot has completely passed, ensuring the darkroom is sealed. This design fully automates the testing process, and the cover is only opened when necessary, maximizing the stability of the darkroom environment.

[0020] 3. This design fully embodies the concept of protecting high-value workpieces. Through precise follow-up and synchronization control, the opening and closing of the cover and the movement of the titanium ingot are perfectly synchronized, avoiding any form of scratching or collision between the edge of the cover and the surface of the titanium ingot, effectively preventing secondary damage to the smooth surface of the titanium ingot during the inspection process. The reset lever mechanism ensures that after each operation cycle, all moving parts can accurately return to their initial position, preparing for the next inspection and guaranteeing the reliability and repeatability of the device operation.

[0021] 4. Overall, this device organically integrates functional modules such as stable environment creation, full-surface scanning, continuous flow operation, and intelligent flexible hazard avoidance. Its ingenious mechanical structure design and well-coordinated control system not only significantly improve the accuracy and reliability of titanium ingot flaw detection but also greatly enhance the overall efficiency and automation level of the inspection operation. It is suitable for integrated application in modern titanium material production lines and has high practical value. Attached Figure Description

[0039] In an embodiment of the present invention, the workflow is as follows: Initialization and Loading: The device is powered on and initialized, and all mechanisms are in their correct positions. The titanium ingot to be inspected is then smoothly placed onto the conveyor belt 603 on the inlet side using a crane or forklift. At this time, the covers 203 at both ends of the inspection box 201 are closed, forming a dark chamber inside.

[0040] Start the conveyor and trigger the follower: Start the second motor 601, the conveyor belt 603 starts running, driving the titanium ingot to move at a constant speed towards the detection box 201. At the same time, when the head of the titanium ingot contacts the lever 703 on the inlet side placement seat, it pushes the follower block 702 to start sliding forward synchronously.

[0041] Synchronous opening of the cover: First, depending on the length and height of the titanium ingot to be conveyed, the third motor 801 is activated to adjust the angle of the deflection frame 803, aligning the multi-stage electric telescopic rod 809 with the actuation point of the cover 203; the fourth motor 804 drives the displacement block 806 to extend to a predetermined distance; the fifth motor 811 adjusts the two multi-stage electric telescopic rods 809 to a suitable opening angle; finally, the multi-stage electric telescopic rods 809 are adjusted to a suitable length. As the titanium ingot moves the lever 703, which in turn moves the follower block 702, the multi-stage electric telescopic rods 809 move, thus opening the cover 203.

[0042] Rotary scanning inspection in a dark chamber: The titanium ingot enters the sealed inspection chamber 201. At this time, the first motor 306 drives the rotating ring 303 and all the cameras 404 on it to revolve around the titanium ingot at high speed. With the titanium ingot being fed axially at a uniform speed, the camera group performs spiral full-coverage image acquisition on the surface of the titanium ingot. The acquired data is transmitted to the computer processing system in real time for defect analysis and judgment.

[0043] Synchronous closing of the cover: When the titanium ingot is fully inside the detection box 201, the follower block 702 reaches the end of the vertical groove 503. At this time, the first tension spring 701 is stretched, and the titanium ingot will press the lever 703. At the same time, the top frame 908 will push the deflection frame 904, and the positioning rod 905 will no longer be inserted in the positioning slot. That is, the lever 703 will move downward. Since there is no titanium ingot to block the lever 703, the follower block 702 can be reset under the pull of the first tension spring 701. As the follower block 702 resets, the multi-stage electric telescopic rod 809 will also reset. Thus, the multi-stage electric telescopic rod 809 can open the cover 203, and the cover 203 closes and seals under its own weight.

[0044] The follower mechanism quickly resets: After the reset is completed, the linear motor 907 retracts the top frame 908, the deflection frame 904 falls back under the action of gravity, the positioning rod 905 re-engages into the slot of the pull plate 902, locking the follower block 702, waiting for the arrival of the next titanium ingot, and starting a new detection cycle.

[0045] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
