[0002] Surge arresters are critical overvoltage protection devices in power systems. Their main body is typically a columnar insulator, such as a porcelain bushing or a composite bushing. During processing, transportation, and assembly, the surge arrester body may bend or deform due to external forces. If the bending degree exceeds the allowable range, it will not only affect its installation accuracy in the power cabinet but may also lead to uneven internal electric field distribution, reducing its protective performance and even causing safety accidents. Therefore, it is necessary to test its bending degree.

However, manual measurement is inefficient, requires multiple adjustments to the measurement position for each test, and cannot achieve continuous testing across the entire length range, making it difficult to accurately reflect the overall bending condition of the workpiece. To address these issues, existing equipment needs to be improved. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 This utility model provides a technical solution: a bending degree detection device for lightning arrester processing, based on... Figure 1 and Figure 2As shown, the positioning mechanism 4 is located on the upper end of the work frame 2, and an electrical control cabinet 1 is located on the other side of the upper end of the work frame 2. The front of the electrical control cabinet 1 has a touch screen 101 and operation buttons 102. Inside the electrical control cabinet 1 are a PLC and a data acquisition card. The PLC communicates with the detection component 8 via the data acquisition card. The PLC model is Mitsubishi FX5U-32MT / ES. The PLC acts as the "brain" of the system, coordinating the actions of each component, controlling the detection process, and achieving automation. The data acquisition card has high-speed and accurate sensor signal acquisition capabilities, providing a data foundation for precise analysis. The touch screen 101 model is Weintek MT8102iE. The touch screen 101 intuitively displays the detection data and results, facilitating operation and result traceability. The bottom of the work frame 2 has movable self-locking rollers 3, and a movable slide 6 is located above the positioning mechanism 4. The movable slide 6 is connected to the upper end of the work frame 2 on both sides via positioning brackets 5. The inner side of the upper end of the movable slide 6 is connected to the mounting slide 7 via an electric linear guide rail. The electric linear guide rail model is THK. The HSR25 uses an electric linear guide to drive the detection component 8 to move at a constant speed, achieving uniform scanning. The inner side of the mounting slide 7 is slidably connected to the outer side of the moving slide 6 via a guide groove 601. The guide groove 601 ensures the straightness of the mounting slide 7 during movement, improving the accuracy of the detection position. The front of the mounting slide 7 is equipped with the detection component 8, which includes a laser displacement sensor and an industrial camera. The laser displacement sensor is a Keyence IL-600. The laser displacement sensor facilitates the core detection element, enabling non-contact, high-precision, and rapid surface contour measurement. The industrial camera assists in imaging, which can be used for visual positioning or recording the appearance of the workpiece, improving the accuracy of the detection results.

[0017] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the positioning mechanism 4 includes an adjusting and moving component and a fixed adjusting component. The adjusting and moving component includes a first placement seat 401, and electric linear guides 402 are symmetrically arranged on both sides of the lower end of the first placement seat 401. The electric linear guides 402 drive the first placement seat 401 to move laterally to adapt to workpieces of different lengths. At the same time, the upper ends of the first placement seat 401 are connected to corresponding electric cylinders 404 through side plates 403. The output ends of the two electric cylinders 404 are respectively connected to the middle of the outer side of the corresponding positioning frame 405. The positioning frame 405 has an L-shaped structure, and a fan-shaped elastic pad 4051 is provided inside the V-shaped groove on the inner side of the positioning frame 405. Magnetic blocks 406 are provided on the upper inner side of the positioning frame 405. The electric cylinders 404 are of the SMC type. The MGPM20-50 uses an electric cylinder 404 to move the positioning frame 405, automatically clamping the workpiece from both sides. The V-groove design enables automatic centering. Protected by elastic pads 4051, excessive clamping force is avoided to prevent damage to the workpiece surface, while also increasing friction to prevent slippage. Magnetic blocks 406 further assist in fixing the positioning frame 405, ensuring stable workpiece position during inspection. The fixing and adjusting assembly includes a second placement seat 407, which has a U-shaped structure. A limiting elastic strip 408 is engaged and connected internally within the second placement seat 407, with a swing arm positioned on the inner side of the limiting elastic strip 408. The second placement seat 407, located away from the adjustment and movement component, has a positioning component 409 in the middle of its side. The middle of one side of the positioning component 409 is connected to the output end of the servo motor 410. The servo motor 410 is connected to the corresponding mounting bracket 411 via an electric guide rail 412. The electric guide rail 412 drives the servo motor 410 and the positioning component 409 to move, which facilitates the positioning of the center of different workpieces. The servo motor 410 drives the positioning component 409 to rotate, so that the workpieces rotate synchronously, which is convenient for the detection component 8 to take pictures and detect their appearance.

[0018] To further explain, the positioning component 409 includes a limiting plate 4091, a locator 4092, and a placement frame 4093. The locator 4092 is located inside one side of the limiting plate 4091 to improve positioning accuracy. Meanwhile, the placement frame 4093 is located outside the locator 4092 on the limiting plate 4091. The placement frame 4093 has a U-shaped structure and a silicone anti-slip pad 4094 is installed inside the placement frame 4093. At the same time, multiple reinforcing protrusions 4095 are equidistantly arranged on both sides of the silicone anti-slip pad 4094. The positioning component 409 facilitates precise positioning of the workpiece from the end, ensuring a unified detection benchmark.

[0019] In use, the surge arrester is placed on the positioning mechanism 4, and then the electric cylinder 404 of the moving component is adjusted to push the positioning frame 405 to clamp the workpiece from both sides. Under the action of the magnetic block 406 and the elastic pad 4051, the workpiece is ensured to be stable and undamaged. The positioning component 409 of the fixed adjustment component accurately positions the workpiece from the end. Then, the PLC system in the electrical control cabinet 1 issues a command, and the electric linear guide rail drives the mounting slide 7 to move the detection component 8 smoothly along the moving slide 6, so that the laser displacement sensor and industrial camera in the detection component 8 continuously scan and photograph the surface of the surge arrester, and collect position data in real time over the entire length range. Finally, the data acquisition card transmits the sensor signal to the PLC, the PLC analyzes and calculates the data to obtain the bending value, and the detection result is displayed on the touch screen 101 for easy viewing by the staff.
