Description

Technical Field

[0001] This utility model relates to the field of wheel hub surface inspection technology, and in particular to an automatic identification device for wheel hub surface defects. Background Technology

[0002] Automatic wheel hub surface defect identification is a system or method that uses advanced technologies (such as machine vision and artificial intelligence algorithms) to automatically detect and identify defects such as scratches, dents, and rust on the surface of wheel hubs. Its main purpose is to improve detection efficiency, accuracy, and consistency, while reducing human intervention. It is widely used in wheel hub quality inspection in fields such as automobile manufacturing and aerospace.

[0003] Patent CN220583779U discloses an auxiliary detection device for wheel hub appearance defects, including a base plate. An automatic rotation mechanism is mounted on the upper surface of the base plate. The automatic rotation mechanism includes a servo motor fixedly connected to the upper surface of the base plate. An operating frame is fixedly mounted on the output end of the servo motor. An operating groove is formed on the upper surface of the operating frame. An adjusting column is rotatably connected to the inner right side wall of the operating groove. Two sliders are threadedly connected to the surface of the adjusting column, and a support plate is fixedly mounted on the upper surface of the sliders. Although this patent, by setting up an automatic rotation mechanism, can drive the wheel hub to rotate automatically, thereby replacing the manual operation of turning the wheel hub, which helps save labor and improve detection efficiency, in actual use, because the arc-shaped support blocks are fixed to the upper end of the support column, the distance between the two arc-shaped support blocks cannot be adjusted. This makes the device unable to adapt to wheel hubs of different sizes, thus limiting the device's applicability.

[0004] Therefore, there is a need for an automatic identification device for wheel surface defects applicable to wheel hubs of various sizes. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, which have the disadvantage that the distance between the two arc-shaped support blocks cannot be adjusted because the arc-shaped support blocks are fixed at the top of the support column, thus limiting the applicability of the device to different sizes of wheel hubs, this utility model provides an automatic wheel hub surface defect identification device applicable to multi-size wheel hubs.

[0006] This utility model provides the following technical solution: an automatic identification device for wheel hub surface defects, which further includes a worktable, cabinet doors, electric guide rails, a slide block, a servo motor, a placement seat, and an identification mechanism. Two cabinet doors are rotatably arranged on the left side of the worktable. An electric guide rail is installed on the top of the worktable. A slide block is slidably arranged on the electric guide rail. A servo motor is installed at the bottom of the slide block. A placement seat is rotatably arranged on the top of the slide block. The output shaft of the servo motor is connected to the placement seat. An identification mechanism is arranged on the worktable. The identification mechanism is used to automatically identify the wheel hub surface. It also includes a first guide rod, a top block, an elastic element, a mounting rod, a cylinder, and a top frame. Multiple first guide rods are fixedly connected to the top of the placement seat. A top block is slidably arranged at one end of the first guide rod. An elastic element is sleeved on the first guide rod. The two ends of the elastic element are respectively connected to the top block and the first guide rod. A mounting rod is fixedly connected to the bottom of the top block. A cylinder is installed at the middle position of the bottom of the placement seat. A top frame is installed on the telescopic rod of the cylinder. The top frame drives the top block to slide along the first guide rod.

[0007] Optionally, the identification mechanism includes an identification box, a control panel, and cameras. The identification box is fixedly connected to the top of the workbench, and control panels are provided on both the left and right sides of the identification box. Multiple cameras are installed on both the left and right sides inside the identification box, and the cameras are electrically connected to the control panels.

[0008] Optionally, it also includes a second guide rod, a protective plate, a fixing block, a screw, and a dual-axis motor. Two second guide rods are fixedly connected to the top of the identification box, and the protective plate is slidably installed on the two second guide rods. Fixing blocks are fixedly connected to the left and right sides of the top of the identification box. A dual-axis motor is installed in the middle of the top of the identification box. Both output shafts of the dual-axis motor are connected to screws. One end of the screw is rotatably connected to the fixing block, and the screw is threadedly connected to the protective plate.

[0009] Optionally, it also includes an anti-slip sleeve, with the top of the block covered with an anti-slip sleeve.

[0010] Optionally, it also includes an observation panel, which is embedded in the protective panel.

[0011] Optionally, the workbench is equipped with storage space.

[0012] Compared with the prior art, this utility model provides an automatic identification device for wheel hub surface defects, which has the following beneficial effects: 1. By controlling the telescopic rod of the cylinder to drive the top frame to rise, when the top frame rises, the pressing mounting rod moves outward, causing the top block to be tightly attached to the inner wall of the wheel hub. When the top block is in complete contact with the wheel hub, the wheel hub is automatically locked, thereby fixing it on the placement seat, realizing the quick locking of wheel hubs of different sizes, and improving the convenience and applicability of the device.

[0013] 2. During the detection process, the servo motor is started. The output shaft of the servo motor rotates, driving the placement seat to rotate slowly, so that the hub can rotate 360° without dead angles, ensuring full recognition.

[0014] 3. The output shaft of the dual-axis motor drives the screw to rotate, which in turn causes the protective plate to close along the second guide rod. After the protective plate closes, it can effectively prevent external light from interfering with the detection and form a closed operating space to ensure operational safety.

Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0023] Example 1: An automatic identification device for wheel hub surface defects, please refer to... Figures 1-6The system includes a workbench 1, cabinet doors 2, electric guide rails 3, slides 4, servo motors 401, a placement seat 5, and an identification mechanism. Two cabinet doors 2 are rotatably mounted on the left side of the workbench 1. An electric guide rail 3 is mounted on the top of the workbench 1, and a slide 4 is slidably mounted on the electric guide rail 3. A servo motor 401 is mounted at the bottom of the slide 4, and a placement seat 5 is rotatably mounted on the top of the slide 4. The output shaft of the servo motor 401 is connected to the placement seat 5. An identification mechanism is installed on the workbench 1 to automatically identify the surface of the wheel hub. The identification mechanism includes an identification box 6, a control panel 601, and cameras 7. The identification box 6 is fixedly connected to the top of the workbench 1. Control panels 601 are located on both the left and right sides of the identification box 6. Several cameras 7 are installed inside the identification box 6 on both the left and right sides. The camera 7 is electrically connected to the control panel 601. Four first guide rods 8 are fixedly connected to the top of the placement base 5. A top block 9 is slidably installed at one end of the first guide rod 8. An elastic element 10 is sleeved on the first guide rod 8. The two ends of the elastic element 10 are connected to the top block 9 and the first guide rod 8 respectively. An installation rod 11 is fixedly connected to the bottom of the top block 9. A cylinder 12 is installed in the middle of the bottom of the placement base 5. A top frame 13 is installed on the telescopic rod of the cylinder 12. The top frame 13 drives the top block 9 to slide along the first guide rod 8. An anti-slip sleeve 14 is sleeved on the top of the top block 9. The anti-slip sleeve 14 enhances the friction and prevents the wheel hub from slipping. An observation plate 20 is embedded in the protective plate 16. The observation plate 20 facilitates the observation of the detection process. The workbench 1 has a storage space inside, which can store tools or spare parts.

[0024] When this device is needed, first, place the wheel hub on the placement seat 5. Then, start the cylinder 12, controlling the extension rod of the cylinder 12 to drive the top frame 13 to rise. When the top frame 13 rises, the pressing mounting rod 11 moves outward, causing the top block 9 to press tightly against the inner wall of the wheel hub. When the top block 9 is in full contact with the wheel hub, the extension rod of the cylinder 12 stops extending, the elastic element 10 is compressed, and the wheel hub is automatically locked, thus fixing it on the placement seat 5. This achieves quick locking of wheel hubs of different sizes, improving the convenience of operation and the efficiency of the device. Subsequently, start the electric guide rail 3, driving the slide 4 to move horizontally, bringing the wheel hub into the detection area of ​​the identification box 6. At the same time, start the camera 7 through the control panel 601. Camera 7 captures images of the wheel hub surface from different angles. The images are analyzed by control panel 601 to automatically identify defects such as scratches, dents, and rust. During the inspection process, servo motor 401 is activated. The output shaft of servo motor 401 rotates to drive the placement seat 5 to rotate slowly, enabling the wheel hub to rotate 360° without dead angles, ensuring comprehensive identification. After identification is completed, camera 7 and servo motor 401 are turned off. Then, the telescopic rod of cylinder 12 is controlled to retract, causing top frame 13 to move downward and no longer press on mounting rod 11. At this time, elastic element 10 rebounds, pushing top block 9 to move inward and reset, releasing the limit on the wheel hub. Finally, electric guide rail 3 drives slide 4 to move out of the inspection area and remove the wheel hub from placement seat 5.

[0025] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 6 Two second guide rods 15 are fixedly connected to the top of the identification box 6. The two second guide rods 15 are slidably equipped with protective plates 16. Fixing blocks 17 are fixedly connected to the left and right sides of the top of the identification box 6. A dual-axis motor 19 is installed in the middle of the top of the identification box 6. Both output shafts of the dual-axis motor 19 are connected to screws 18. One end of the screw 18 is rotatably connected to the fixing block 17, and the screw 18 is threadedly connected to the protective plate 16.

[0026] When the wheel hub enters the detection area of ​​the identification box 6, the dual-axis motor 19 is started. The output shaft of the dual-axis motor 19 rotates to drive the screw 18 to rotate, which in turn drives the protective plate 16 to close along the second guide rod 15. After the protective plate 16 is closed, it can effectively prevent external light from interfering with the detection, and at the same time form a closed operating space to ensure operational safety.
