Description

Technical Field

[0001] This utility model relates to the field of insulation testing technology for insulating products, and in particular to an insulation testing device for processing insulating products. Background Technology

[0002] Insulating products are rubber products made primarily of rubber with added additives. They are highly elastic but difficult to conduct electricity. As electrical insulators, insulating rubber products, in addition to possessing good physical and mechanical properties of rubber, should not contain a large number of freely moving charges within them, i.e., they should have good electrical insulation properties. These properties are usually comprehensively measured by the magnitude of values ​​such as volume insulation resistance, breakdown voltage, dielectric constant, power factor, and corona discharge. Therefore, after the insulating products are processed, insulation testing devices are used to test their insulation properties to ensure their performance.

[0003] When testing insulating products, it is usually necessary to place the product on a testing table, then place the testing probe on one side of the product and place the current receiving piece on the other side of the product. The insulation performance of the product is judged by whether a current can be formed between the two. However, most existing testing devices can only fix the product in a designated position and cannot perform multi-directional testing on different positions of the product, which has certain limitations. Since insulating products need to be fixed to prevent them from sliding before testing, the fixing structure of existing testing devices is mostly too complicated, which requires a lot of time and effort to operate and affects work efficiency.

[0004] An existing patent (publication number: CN217879491U) discloses a multi-directional insulation testing device for processing insulating products. This utility model enables the clamping plate to slide quickly left and right on the guide base through a linkage rod. In this device, the first support rod, the sliding seat, the support seat, and the second support rod are all omnidirectionally rotatably connected in the horizontal direction, and the first support rod and the support seat are rotatably connected in the vertical direction. This allows the operator to adjust the position of the discharge probe in both the horizontal and vertical directions, thereby performing multi-directional insulation testing and improving the accuracy of the test results.

[0005] To address the aforementioned issues, existing patents offer solutions. However, the insulation testing devices proposed in these patents can only clamp insulating products for top-surface testing. Although the multi-directional support mechanism can adjust the position of the discharge probe, improving the comprehensiveness of top-surface testing to some extent, it still cannot test other surfaces. In actual production and application, comprehensive testing of the insulation performance of all surfaces of insulating products is crucial. For example, in high-voltage electrical equipment, poor insulation performance on any surface can lead to safety accidents. This device lacks a structure to rotate the object being tested, resulting in incomplete functionality, limited testing capabilities, and an inability to perform omnidirectional scanning. It is difficult to meet the safety requirements in complex environments and cannot provide sufficient and reliable data in production quality control and product quality certification, thus limiting the testing accuracy.

[0006] Therefore, an insulation testing device for processing insulating products is proposed. Utility Model Content

Its clamping plate can only hold the insulating product for top surface testing. Although the multi-directional support mechanism can adjust the position of the discharge probe, which improves the comprehensiveness of top surface testing to a certain extent, it still cannot test other surfaces. In actual production and application, it is crucial to comprehensively test the insulation performance of all surfaces of the insulating product. For example, in the insulating components of high-voltage electrical equipment, poor insulation performance on any surface may cause safety accidents. The device lacks a structure to rotate the object being tested, its function is incomplete, its testing capability is limited, it cannot perform all-round scanning testing, and it is difficult to meet the safety requirements of use in complex environments. In the production quality control and product quality certification stages, it cannot provide sufficient and reliable data, which limits the testing accuracy.

[0013] Preferably, the adjustment structure includes a shift groove formed on the rear side of the top of the testing platform, an adjustment screw is rotatably connected inside the shift groove, the left side of the adjustment screw passes through the interior of the shift groove and extends to the left side of the testing platform, and a threaded block is threadedly connected to the surface of the adjustment screw, the threaded block being slidably connected inside the shift groove.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An insulation testing device for processing insulating products includes a testing platform 1. A touch screen display controller 2 and an electrical control box 3 are respectively arranged on the left and right sides of the top of the testing platform 1. A support base 4 is bolted to the front side of the top of the testing platform 1. A receiving plate 5 is arranged on the top of the support base 4. A fixed rotation mechanism 6 is arranged on the top of the support base 4. An adjustment structure 7 is arranged on the rear side of the top of the testing platform 1. A discharge probe 8 is arranged at the bottom of the adjustment structure 7. The discharge probe 8 and the receiving plate 5 are both electrically connected to the electrical control box 3.

[0029] The fixed-rotation mechanism 6 includes support plates 61 bolted to both sides of the top of the support base 4. A push-clamp structure 62 is provided on the inner side of the right support plate 61. A servo motor 63 is bolted to the left side of the left support plate 61. The output end of the servo motor 63 passes through the left side of the left support plate 61. A clamping plate 64 is fixedly connected to the output end of the servo motor 63. The clamping plate 64 is located on the left side of the push-clamp structure 62. A deformation pad 65 is adhered to the inner side of the clamping plate 64.

[0030] In this embodiment: By setting up a fixed-rotation mechanism 6 and an adjustment structure 7, when the test begins, the insulating product is first placed between the clamping plate 64 and the pushing clamping structure 62 of the fixed-rotation mechanism 6. The push clamping structure 62 is moved towards the clamping plate 64 by the touch screen display controller 2. The two work together to clamp and position the insulating product. Then, the discharge probe 8 discharges, and the receiving plate 5 receives the signal. At the same time, the electrical control box 3 detects the current and calculates the insulation performance of the insulating product, and transmits the data to the touch screen display controller 2. After the top surface test is completed, the touch screen display controller 2 starts the servo motor 63 in the fixed-rotation mechanism 6 according to the set program, driving... The clamping plate 64 rotates slowly, causing the insulating product to rotate to different surfaces or angles and then stop, allowing for repeated testing and current calculation. This enables insulation testing on different surfaces of the insulating product, solving the problem of limited testing functionality in existing devices and achieving multi-surface testing. In addition, the adjusting structure 7 can adjust the discharge probe 8 in the horizontal and vertical directions, which, combined with the fixed-rotation mechanism 6, rotates the object being tested, further improving the flexibility and comprehensiveness of the testing. This allows for more precise testing of different positions on the insulating product, enhancing testing accuracy, providing reliable data for production and certification, meeting testing needs in complex environments, and ensuring the safety of electrical equipment.

[0031] Specifically, such as Figure 3 As shown, the push-clamp structure 62 includes an electric push rod 621 bolted to the right side of the right side support plate 61. The electric push rod 621 is electrically connected to the touch screen display controller 2, and the output end of the electric push rod 621 passes through the right side of the right side support plate 61.

[0032] Specifically, such as Figure 3 As shown, the output end of the electric push rod 621 is fixedly connected to a connecting plate 622, and a pressure sensor 623 is bolted to the left side of the connecting plate 622. The pressure sensor 623 is electrically connected to the touch screen display controller 2.

[0033] Specifically, such as Figure 3 As shown, a push plate 624 is provided on the left side of the connecting plate 622. The push plate 624 is located to the left of the pressure sensor 623. Slide rods 625 are fixedly connected to the four corners of the right side of the push plate 624. The right side of the slide rods 625 passes through the left side of the connecting plate 622. An auxiliary clamping plate 626 is rotatably connected to the left side of the push plate 624. The auxiliary clamping plate 626 is located to the right of the clamping plate 64.

[0034] In this embodiment: By setting the push-clamp structure 62, when fixing the insulating product, the operator only needs to input a command on the touch screen display controller 2, and the electric push rod 621 electrically connected to the controller will be activated. The output end of the electric push rod 621 pushes the connecting plate 622 to the left, and the connecting plate 622 drives the push plate 624 to advance synchronously. The slide rods 625 at the four corners on the right side of the push plate 624 slide on the connecting plate 622, playing a stabilizing and guiding role. When the auxiliary clamping plate 626 on the left side of the push plate 624 cooperates with the clamping rotating plate 64 to clamp the insulating product, the push plate 624 squeezes the connecting plate. The pressure sensor 623 on the left side of 622 monitors the pressure in real time and feeds the data back to the touch screen display controller 2. When the pressure reaches the predetermined range, the touch screen display controller 2 controls the electric push rod 621 to stop, thereby accurately controlling the clamping force and avoiding damage to the product due to excessive force or insecure fixation due to insufficient force. In addition, the rotatable auxiliary clamping plate 626 facilitates the rotation of the auxiliary clamping plate 64 to drive the insulating product to rotate, which not only improves the stability and adaptability of clamping, but also ensures that the product will not shake during the test, laying the foundation for accurate detection of insulation performance.

[0035] Specifically, such as Figure 4 As shown, the adjustment structure 7 includes a shift groove 71 opened on the rear side of the top of the detection table 1. An adjustment screw 72 is rotatably connected inside the shift groove 71. The left side of the adjustment screw 72 passes through the interior of the shift groove 71 and extends to the left side of the detection table 1. A threaded block 73 is threadedly connected to the surface of the adjustment screw 72. The threaded block 73 is slidably connected inside the shift groove 71.

[0036] Specifically, such as Figure 4As shown, a lifting rod 74 is fixedly connected to the top of the threaded block 73, and an electric telescopic rod 75 is fixedly connected to the front side of the top of the lifting rod 74. The electric telescopic rod 75 is electrically connected to the touch screen display controller 2. The telescopic end of the electric telescopic rod 75 passes through the top of the lifting rod 74. An insulating plate 76 is fixedly connected to the telescopic end of the electric telescopic rod 75. The bottom of the insulating plate 76 is bolted to the top of the discharge probe 8.

[0037] In this embodiment: By setting the adjustment structure 7, when the position of the discharge probe 8 needs to be adjusted, the adjustment screw 72 can be rotated. The adjustment screw 72 rotates in the shifting groove 71, and the threaded block 73 connected to it will slide left and right in the shifting groove 71, realizing the coarse adjustment of the discharge probe 8 in the horizontal direction. In this way, the discharge probe 8 can be quickly moved to the approximate horizontal position of the target detection area. If further precise adjustment is required, the touch screen display controller 2 can be operated to control the electric telescopic rod 75 electrically connected to the touch screen display controller 2 to work. The telescopic end of the electric telescopic rod 75 drives the insulating plate 76 to move up and down, thereby precisely adjusting the vertical height of the discharge probe 8. In this way, the position of the discharge probe 8 in the horizontal and vertical directions can be flexibly adjusted according to the shape, size and specific detection requirements of the insulating product. Combined with the fixed rotation mechanism 6 to rotate the detection object, accurate detection of different positions of the insulating product can be achieved, effectively improving the detection accuracy.

[0038] Specifically, such as Figure 5 As shown, the deformation pad 65 is made of elastic material, and anti-slip texture is provided on the right side of the deformation pad 65. The anti-slip texture is in the shape of a grid.

[0039] Specifically, such as Figure 4 As shown, an adjustment handle is fixedly connected to the left side of the adjustment screw 72. The adjustment handle is disc-shaped.

[0040] In this embodiment: by using an elastic material to make a deformation pad 65, the clamping plate 64 can act as a buffer when it comes into contact with the insulating product, avoiding damage to the product surface from rigid clamping. At the same time, its elasticity can make the clamping tighter. The grid-shaped anti-slip texture increases the friction between the pad and the insulating product, preventing the product from sliding during the test and ensuring the accuracy of the test. In addition, the disc-shaped adjustment handle is convenient for the operator to grip and apply force. Turning the adjustment handle can easily drive the adjustment screw 72 to rotate, thereby adjusting the horizontal position of the discharge probe 8 in the adjustment structure 7, providing a better user experience for the entire insulation test.

[0041] Working Principle: In the process of using the insulation testing device for insulating products, firstly, at the start of the test, the insulating product is placed between the clamping plate 64 and the auxiliary clamping plate 626. The operator inputs a command on the touch screen display controller 2, and the electric push rod 621 is activated. Its output end pushes the connecting plate 622 and the push plate 624 to the left. The slide rod 625 on the right side of the push plate 624 slides on the connecting plate 622 to provide a stable guide. When the auxiliary clamping plate 626 on the left side of the push plate 624 clamps the insulating product with the clamping plate 64, the push plate 624 squeezes the pressure sensor 623. The pressure sensor 623 monitors the pressure in real time and feeds back the data. When the predetermined range is reached, the touch screen display controller 2 controls the electric push rod 621 to stop, precisely controlling the clamping force. The rotatable auxiliary clamping plate 626 can adapt to products of different shapes, assisting the clamping plate 64 in rotating the product and ensuring the stability of the product during the test. Next, the discharge probe 8 discharges, the receiving plate 5 receives the signal, and the electrical control box 3 detects the current and... The insulation performance of the top surface of the insulating product is calculated and the data is transmitted to the touch screen display controller 2. After the top surface detection is completed, the touch screen display controller 2 starts the servo motor 63 according to the program, which drives the clamping plate 64 to rotate the insulating product to different surfaces or angles for detection and current calculation again, realizing multi-face detection. During the detection process, if it is necessary to adjust the position of the discharge probe 8, the disc-shaped adjustment handle is rotated to drive the adjustment screw 72, so that the threaded block 73 slides in the moving groove 71 to achieve coarse horizontal adjustment of the discharge probe 8. The touch screen display controller 2 controls the electric telescopic rod 75 to move the insulating plate 76 and the discharge probe 8 up and down to precisely adjust the vertical height. Combined with the rotation of the object being detected, accurate detection of different positions of the insulating product is achieved. In addition, the elastic deformation pad 65 on the inner side of the clamping plate 64 has a buffering effect to avoid damage to the surface of the product, and the grid anti-slip texture increases friction to prevent the product from sliding, ensuring accurate detection and providing a good user experience for the entire detection work.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
