Description

Technical Field

[0001] This utility model relates to the field of magnetic core magnetic force testing technology, specifically a magnetic force testing device for magnetic core processing and production. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. In order to increase the magnetic induction intensity of the electromagnet, a magnetically conductive material is placed in the magnetic circuit of the inductor coil.

[0003] After the magnetic core is processed, its magnetic force is tested. This is usually done by combining the magnetic core with an electromagnet and then manually pulling the magnetic core. However, this testing method requires manual operation and is highly subjective in reading the data, making it difficult to obtain accurate data. This inaccurate data affects the processing of the magnetic core. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic force detection device for magnetic core processing, in order to solve the problem mentioned in the background art that requires manual operation, has a high degree of subjectivity in data reading, and cannot accurately read the data, resulting in inaccurate detection data and affecting the processing of magnetic cores.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic force detection device for magnetic core processing and production, comprising a test frame, a fixing plate fixedly connected to the upper outer surface of the test frame, a cylinder fixedly connected to the upper surface of the fixing plate, a connecting plate connected to the output shaft of the cylinder, a display fixedly connected to the lower surface of the connecting plate, a tension sensor fixedly connected to the lower surface of the display, a clamping plate fixedly connected to the lower surface of the tension sensor, a sliding groove formed on the lower surface of the clamping plate, a slider slidably connected to the inner side of the sliding groove, a clamping plate fixedly connected to the lower surface of the slider, a bidirectional lead screw threadedly connected to the inner side of the slider, and a rotating ring fixedly connected to the outer surface of the bidirectional lead screw.

[0006] Preferably, a power board is fixedly connected to the upper surface of the lower end of the test fixture, a pole is fixedly connected to the upper surface of the power board, an electromagnet is slidably connected to the outer surface of the pole, connecting rods are rotatably connected to both sides of the upper surface of the power board, and pressure plates are fixedly connected to the outer surface of the connecting rods.

[0007] Preferably, both the fixing plate and the connecting plate are plate-shaped, and the display and the tension sensor are fixedly connected to the bottom of the connecting plate. Their function is to activate the cylinder, causing the output shaft of the cylinder to drive the connecting plate, the display, the tension sensor and the clamping plate to move downward, thereby causing the magnetic core to come into contact with or disconnect from the electromagnet, thus detecting the magnetic force of the magnetic core.

[0008] Preferably, the clamping plate is U-shaped, the sliding groove is T-shaped, and the slider is in two sets slidably connected to the inside of the sliding groove. Its function is to facilitate the fixing of the magnetic core to the bottom of the clamping plate by sliding the two sets of sliding grooves in a direction closer to each other on the inside of the slider.

[0009] Preferably, the clamping plate is L-shaped and there are two sets of clamping plates. The bidirectional lead screw is rod-shaped and threadedly connected to the two sets of sliders. Its function is to rotate the rotating ring, thereby causing the rotating ring to drive the bidirectional lead screw to rotate, thereby causing the two sets of sliders to slide towards each other on the inner side of the slide groove, thereby causing the clamping plate to move synchronously, thus clamping the magnetic core between the two sets of clamping plates.

[0010] Preferably, the pole post is cylindrical in shape and there are two sets of pole posts. The lower end of the electromagnet is provided with a circular groove that matches the two sets of pole posts. Its function is to connect the electromagnet to the two sets of pole posts, so that when energized, the electromagnet can generate an attractive force, thereby attracting the magnetic core and facilitating the detection of the magnetic force of the magnetic core.

[0011] Preferably, the connecting rod is rod-shaped and rotatably connected to the upper surface of the power board. The pressure plate is plate-shaped and its function is to rotate the connecting rod so that the pressure plate rotates, thereby causing the two sets of pressure plates to slide and connect to the upper surface of the electromagnet, thus fixing the electromagnet above the power board.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By placing the magnetic core under the clamping plate and manually rotating the rotating ring, the rotating ring drives the bidirectional lead screw to rotate, thereby causing the two sets of sliders to slide towards each other on the inner side of the slide groove. This causes the two sets of clamping plates to move synchronously, thus fixing the magnetic core in the inner side of the two sets of clamping plates, which facilitates the subsequent magnetic force testing of the magnetic core.

[0014] 2. By rotating the connecting rod, the pressure plate rotates, causing the two sets of pressure plates to slide and connect to the upper surface of the electromagnet, thus fixing the electromagnet above the power board. Then, by turning on the power, the cylinder is activated, causing the cylinder's output shaft to move the connecting plate, display, tension sensor, and clamping plate downwards, bringing the magnetic core into contact with the electromagnet. Activating the electromagnet again causes it to generate an attractive force, drawing the magnetic core together. Activating the cylinder again causes it to move the clamping plate upwards. Because the electromagnet attracts the magnetic core, the tension sensor generates a pulling force. When the magnetic core disconnects from the electromagnet, the tension value generated by the tension sensor is displayed on the screen, allowing for accurate reading of the magnetic force value on the display and making the magnetic force detection data of the magnetic core more accurate.

[0025] Furthermore, both the fixing plate 2 and the connecting plate 4 are plate-shaped. The display 5 and the tension sensor 6 are fixedly connected to the bottom of the connecting plate 4. Their function is to activate the cylinder 3, so that the output shaft of the cylinder 3 drives the connecting plate 4, the display 5, the tension sensor 6 and the clamping plate 7 to move downward, thereby making the magnetic core contact with or disconnect from the electromagnet 15, so as to detect the magnetic force of the magnetic core.

[0026] Furthermore, the clamping plate 7 is U-shaped, the slide groove 8 is T-shaped, and the slider 9 is connected in two sets to the inside of the slide groove 8. Its function is to facilitate the fixing of the magnetic core to the bottom of the clamping plate 7 by sliding the two sets of slide grooves 8 in a direction closer to each other on the inside of the slider 9.

[0027] Furthermore, the clamping plate 10 is in the shape of an "L" plate, and there are two sets of clamping plates 10. The bidirectional lead screw 11 is rod-shaped and is threadedly connected to the two sets of sliders 9. Its function is to rotate the rotating ring 12, thereby causing the rotating ring 12 to drive the bidirectional lead screw 11 to rotate, thereby causing the two sets of sliders 9 to slide in the inner side of the slide groove 8 towards each other, thereby causing the clamping plate 10 to move synchronously, thereby clamping the magnetic core between the two sets of clamping plates 10.

[0028] Furthermore, the pole post 14 is cylindrical in shape and there are two sets of pole posts 14. The lower end of the electromagnet 15 is provided with a circular groove that matches the two sets of pole posts 14. Its function is to connect the electromagnet 15 with the two sets of pole posts 14, so that when energized, the electromagnet 15 can generate an attractive force, thereby attracting the magnetic core, which facilitates the detection of the magnetic force of the magnetic core.

[0029] Furthermore, the connecting rod 16 is rod-shaped and rotatably connected to the upper surface of the power board 13. The pressure plate 17 is plate-shaped, and its function is to rotate the connecting rod 16 so that the pressure plate 17 rotates, thereby causing the two sets of pressure plates 17 to slide and connect to the upper surface of the electromagnet 15, thereby fixing the electromagnet 15 above the power board 13.

[0030] Working principle: A fixing plate 2 is fixedly connected to the upper outer surface of the test frame 1. A cylinder 3 is fixedly connected to the upper surface of the fixing plate 2. The output shaft of the cylinder 3 is connected to a connecting plate 4. A display 5 is fixedly connected to the lower surface of the connecting plate 4. A tension sensor 6 is fixedly connected to the lower surface of the display 5. A clamping plate 7 is fixedly connected to the lower surface of the tension sensor 6. A groove 8 is opened on the lower surface of the clamping plate 7. A slider 9 is slidably connected to the inner side of the groove 8. A clamping plate 10 is fixedly connected to the lower surface of the slider 9. A bidirectional lead screw 11 is threadedly connected to the inner side of the slider 9. A rotating ring 12 is fixedly connected to the outer surface of the bidirectional lead screw 11. By placing the magnetic core under the clamping plate 7 and manually rotating the rotating ring 12, the rotating ring 12 drives the bidirectional lead screw 11 to rotate, thereby driving the two sets of sliders 9 to slide towards each other on the inner side of the groove 8. This causes the two sets of clamping plates 10 to move synchronously, thereby fixing the magnetic core in the inner side of the two sets of clamping plates 10, which facilitates the subsequent magnetic force detection of the magnetic core.

[0031] A power board 13 is fixedly connected to the upper surface of the lower end of the test fixture 1. A pole post 14 is fixedly connected to the upper surface of the power board 13. An electromagnet 15 is slidably connected to the outer surface of the pole post 14. Connecting rods 16 are rotatably connected to both sides of the upper surface of the power board 13. Pressure plates 17 are fixedly connected to the outer surface of the connecting rods 16. After connecting the electromagnet 15 and the pole post 14 according to their positive and negative poles, rotating the connecting rods 16 causes the pressure plates 17 to rotate, thereby causing the two sets of pressure plates 17 to slide on the upper surface of the electromagnet 15, thus fixing the electromagnet 15 above the power board 13. Then, by turning on the power, the cylinder 3 is started. The output shaft of cylinder 3 drives connecting plate 4, display 5, tension sensor 6, and clamping plate 7 downward, causing the magnetic core to come into contact with electromagnet 15. Activating electromagnet 15 generates attraction, drawing it towards the magnetic core. Activating cylinder 3 again causes clamping plate 7 to move upward. The attraction between electromagnet 15 and the magnetic core causes tension sensor 6 to generate tension. Once the magnetic core is disconnected from electromagnet 15, the tension value generated by tension sensor 6 is displayed on display 5, allowing for precise reading of the magnetic force value and more accurate magnetic force detection data for the magnetic core.
