Description

Technical Field

[0001] This utility model relates to the field of inspection tools, and in particular to an inspection tool for inspecting magnetic core delamination. Background Technology

[0002] Inspection fixtures are specialized testing equipment used to test various parameters and performance of magnetic cores. They are mainly used for quality control in the production of electronic components to ensure that the performance of magnetic cores meets design standards, improve product reliability and energy efficiency, and are widely used in fields such as electronic manufacturing and power equipment.

[0003] Existing inspection tools lack the function of quickly detecting magnetic core delamination. Without this function, traditional visual inspection or tapping and listening methods may be inefficient, highly dependent on personnel experience and condition, and prone to fatigue-induced missed detections during long-term operation.

[0004] Therefore, given the lack of rapid detection of magnetic core delamination in existing inspection tools, the low efficiency of traditional detection methods, their high dependence on personnel experience and condition, and the tendency for fatigue-induced missed detections during long-term operation, there is an urgent need to design a new type of inspection tool for detecting magnetic core delamination. Utility Model Content

[0005] In order to overcome the lack of existing inspection tools to quickly detect magnetic core delamination, traditional inspection methods are inefficient, highly dependent on personnel experience and condition, and prone to fatigue-induced missed detections during long-term operation.

[0006] The technical solution of this utility model is as follows: a test fixture for inspecting magnetic core delamination includes a base; it also includes a test platform, a sleeve and a counterweight ring. The test platform is installed at the middle position of the upper surface of the base, the sleeve is installed at the middle position of the upper surface of the test platform, and a lifting assembly is provided on the rear side of the upper surface of the base. The lifting end of the lifting assembly is provided with a counterweight ring.

[0007] Preferably, by setting up a sleeve, the operator can place the magnetic core concentrically with the testing platform each time, thus preventing deviations in test results due to positional shifts. Furthermore, by setting up a testing platform, which is slightly smaller than the magnetic core, the outer portion of the core can be suspended. Finally, by placing a counterweight ring on the upper surface of the magnetic core and observing whether the suspended portion sinks, it can be determined whether delamination has occurred. This achieves a quick and convenient method for detecting magnetic core delamination, addressing the lack of rapid detection of magnetic core delamination in existing inspection tools. Without this function, traditional visual inspection or tapping and listening methods are inefficient, highly dependent on operator experience and condition, and prone to fatigue-induced missed detections over long periods.

[0008] Preferably, the lifting assembly includes a lifting frame, a limiting rod, a slider, and a clamp; the lifting frame is installed on the rear side of the upper surface of the base, the limiting rod is installed on the right side of the inner upper surface of the lifting frame, the slider is slidably connected to the outer surface of the limiting rod, the clamp is installed on the front surface of the slider, and the inner surface of the clamp is in contact with the outer surface of the counterweight ring.

[0009] Preferably, a limit rod 2 is installed on the left side of the upper inner surface of the lifting frame, and a slide groove is provided through the upper surface of the slider on the left side, with the limit rod 2 slidably connected to the slide groove.

[0010] Preferably, the upper surface of the lifting frame is equipped with symmetrical support plates, and a pulley is rotatably connected between the two support plates. A pull rope is connected to the upper surface of the slider, and the pull rope and the pulley are in contact.

[0011] Preferably, the lifting frame has mounting slots on both the left and right sides inside, and several rollers are rotatably connected inside the two mounting slots.

[0012] Preferably, a weight-reducing groove is provided through the upper surface of the sleeve, and the weight-reducing groove passes through the testing platform and the base.

[0013] Preferably, the rear surface of the lifting frame is connected to one end of two symmetrical support plates, and the other ends of the two support plates are connected to the upper surface of the base.

[0014] The beneficial effects of this utility model are: 1. By setting up a sleeve, the geometric constraint function of the sleeve ensures that when the operator performs the core positioning operation, the core axis and the center axis of the testing platform are forcibly aligned, eliminating the axial offset error caused by manual placement, thereby ensuring the geometric consistency of the testing benchmark. The testing platform is specially designed to form a stepped bearing interface, and its bearing surface diameter is smaller than the core benchmark outer diameter, so that the outer edge of the core forms an annular suspended area. During testing, by placing a counterweight ring on the upper surface of the core, when the core has a delamination defect, the suspended area will produce an observable deformation and sinking under the load, thereby achieving the purpose of quickly and conveniently detecting whether the core is delaminating. This solves the problem that existing inspection tools lack the function of quickly detecting core delamination. Without the function of quickly detecting core delamination, traditional visual inspection or tapping and listening methods may be inefficient, highly dependent on the experience and condition of personnel, and prone to fatigue-induced missed detections during long-term operation.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-4 This utility model provides an embodiment of a testing tool for inspecting magnetic core delamination, comprising a base 1; and further comprising a testing platform 2, a sleeve 3, and a counterweight ring 5. The testing platform 2 is installed at the middle position of the upper surface of the base 1, and the sleeve 3 is installed at the middle position of the upper surface of the testing platform 2. A lifting assembly is provided on the rear side of the upper surface of the base 1, and the counterweight ring 5 is provided inside the lifting end of the lifting assembly. By setting the sleeve 3, the operator can place the magnetic core concentrically with the testing platform 2 each time, so that the test results will not be deviated due to positional shift during testing. Furthermore, by setting the testing platform 2, which is slightly smaller than the magnetic core, the outer part of the magnetic core can be suspended. Finally, by placing the counterweight ring 5 on the upper surface of the magnetic core, it is observed whether the suspended part of the magnetic core sinks, thereby determining whether the magnetic core has delamination, thus achieving the purpose of quickly and conveniently detecting whether the magnetic core has delamination.

[0019] Please see Figures 1-3In this embodiment, the lifting assembly includes a lifting frame 401, a limiting rod 402, a slider 403, and a clamp 404. The lifting frame 401 is mounted on the rear side of the upper surface of the base 1. The limiting rod 402 is mounted on the right side of the inner upper surface of the lifting frame 401. The slider 403 is slidably connected to the outer surface of the limiting rod 402. The clamp 404 is mounted on the front surface of the slider 403. The inner surface of the clamp 404 is in contact with the outer surface of the counterweight ring 5. By setting the limiting rod 402, the freedom of the slider 403 is restricted, allowing it to slide up and down along the limiting rod 402. When the slider 403 moves, it drives the clamp 404 to move. When the clamp 404 moves, it drives the counterweight ring 5 to move, thereby achieving the integration of the counterweight ring 5 and the inspection fixture, avoiding the possibility of loss if the inspection fixture and the counterweight ring 5 are used separately. The lifting frame 401... A limiting rod 2 6 is installed on the left side of the upper internal surface. A groove 7 is provided through the upper surface of the slider 403 on the rear left side. The limiting rod 2 6 is slidably connected to the groove 7. By setting the groove 7, the other side of the slider 403 is restricted to rotation by the limiting rod 2 6, thereby limiting the position of the counterweight ring 5 and making the counterweight ring 5 and the gauge concentric. This achieves the purpose of not needing to adjust the position to align with the concentric point during use. The upper surface of the lifting frame 401 is equipped with symmetrical support plates 8. A pulley 9 is rotatably connected between the two support plates 8. A pull rope 10 is connected to the upper surface of the slider 403. The pull rope 10 and the pulley 9 are in contact. By setting the pulley 9 as a rollable fixed fulcrum for the pull rope 10, the operator can move the slider 403 and its connected parts simply by pulling or releasing the pull rope 10, thereby facilitating the operator's work.

[0020] Please see Figures 2-4 In this embodiment, the lifting frame 401 has mounting grooves 11 on both the left and right sides inside. Several rollers 12 are rotatably connected inside the two mounting grooves 11. By setting the rollers 12, friction between the slider 403 and the inside of the lifting frame 401 during movement is avoided, which would cause the slider 403 to get stuck. This achieves the purpose of assisting the slider 403 in moving. The upper surface of the sleeve 3 has a weight reduction groove 13 that runs through the detection platform 2 and the base 1. By setting the weight reduction groove 13, the overall weight of the inspection tool is reduced, and the materials required to make the inspection tool are reduced, thereby reducing the manufacturing cost of the inspection tool. The rear surface of the lifting frame 401 is connected to one end of two symmetrical support plates 14. The other end of the two support plates 14 is connected to the upper surface of the base 1. By setting the support plates 14, a triangular support is formed between the lifting frame 401 and the base 1, thereby strengthening the installation strength of the lifting frame 401.

[0021] During operation, a limiting rod 402 is used to restrict the freedom of the slider 403, allowing it to slide up and down along the limiting rod 402. When the slider 403 moves, it drives the clamp 404 to move, which in turn drives the counterweight ring 5 to move. This integrates the counterweight ring 5 with the fixture, preventing potential loss if the fixture and counterweight ring 5 are used separately. A groove 7 is provided, allowing the other side of the slider 403 to be rotated by a limiting rod 6, thus defining the position of the counterweight ring 5 and ensuring it is concentric with the fixture. This eliminates the need for adjustment during use to align the counterweight ring with the fixture. A pulley 9 is provided for the pull rope 10 to roll. The movable fixed fulcrum allows the operator to move the slider 403 and its connected parts simply by pulling or releasing the pull rope 10, thus facilitating the operator's work. By setting the roller 12, friction between the slider 403 and the inside of the lifting frame 401 during movement is avoided, preventing the slider 403 from getting stuck, thus assisting the movement of the slider 403. By setting the weight reduction groove 13, the overall weight of the fixture is reduced, and the materials required for manufacturing the fixture are also reduced, thus reducing the manufacturing cost of the fixture. By setting the support plate 14, a triangular support is formed between the lifting frame 401 and the base 1, thereby strengthening the installation strength of the lifting frame 401.

[0022] Through the above steps, by setting the sleeve 3, the geometric constraint function of the sleeve 3 ensures that when the operator performs the magnetic core positioning operation, the magnetic core axis and the central axis of the detection platform 2 are forcibly aligned, eliminating the axial offset error caused by manual placement, thereby ensuring the geometric consistency of the detection benchmark. The detection platform 2 is specially designed to form a stepped bearing interface, and its bearing surface diameter is smaller than the outer diameter of the magnetic core benchmark, so that the outer edge of the magnetic core forms an annular suspended area. During the inspection, by placing the counterweight ring 5 on the upper surface of the magnetic core, when the magnetic core has a delamination defect, the suspended area will produce an observable deformation and sinking under the load, thereby achieving the purpose of quickly and conveniently detecting whether the magnetic core is delaminating, so as to solve the problem that the existing inspection tools lack the function of quickly detecting magnetic core delamination. Without the function of quickly detecting magnetic core delamination, the traditional visual inspection or tapping and listening method may be inefficient, highly dependent on the experience and condition of the personnel, and prone to fatigue-induced missed detections during long-term operation.
