Description

Technical Field

[0001] This utility model relates to the field of magnetic core burr removal technology, specifically a magnetic core burr removal mechanism adaptable to different sizes. Background Technology

[0002] A magnetic core is a material used in electromagnetic devices to concentrate and guide magnetic fields. It is typically made of ferrite, silicon steel sheets, or other magnetic materials. A burr removal mechanism for magnetic cores of different sizes is usually a device designed to remove burrs from the surface or edges during the manufacturing and processing of magnetic cores. For example, an adaptive burr removal mechanism for magnetic cores (publication number CN222386592U) includes: a worktable with collection ports on both sides of the top center; a side cover fixedly installed on one side of the worktable; stable feet fixedly installed at the four corners of the bottom of the worktable; and stable support feet fixedly installed on both sides below the two ends of the worktable; a burr removal mechanism above the worktable to clean the burrs on the magnetic core; and a cleaning mechanism inside the worktable cavity to collect and clean the burr waste removed by the burr removal mechanism. The deburring mechanism can be used to fix and remove burrs from magnetic cores of various sizes, improving the practicality, adaptability and flexibility of the magnetic core burr removal mechanism. At the same time, the rotation of the magnetic core, combined with the rotation of the deburring brush roller, improves the efficiency and quality of deburring.

[0003] Although the above-mentioned technology can collect and clean the burr waste removed by the deburring mechanism through the cleaning mechanism, its cleaning effect is limited. The cleaning structure of the above-mentioned technology cleans by air, but the burrs and debris generated during the polishing of the magnetic core are magnetic, and the air force cannot remove those fine particles that adhere to the surface or corners of the magnetic core.

[0023] 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.

[0024] This utility model provides the following technical solution: a burr removal mechanism for magnetic cores of different sizes.

[0025] Example 1: The drain pipe 7 and spray nozzle 8 can be used to clean the magnetic core and the top of the water tank 1. Figures 1-6 As shown, the system includes a water tank 1, a support frame 2 on top of the water tank 1, a drive motor installed at the bottom of the support frame 2, a rotating shaft 3 at the output end of the drive motor, a turntable 4 on top of the rotating shaft 3, and a protective cover 5 on top of the water tank 1. A water pump is installed inside the water tank 1, and an outlet pipe 6 is installed at the output end of the water pump. The other end of the outlet pipe 6 passes through the water tank 1 and the protective cover 5 and is equipped with a rotary joint. The other end of the rotary joint is equipped with a drain pipe 7, and a row of spray nozzles 8 is installed at the bottom of the drain pipe 7. A water inlet hole 13 is opened at the top of the water tank 1. Support bars are installed at both ends inside the water tank 1, and filter plates 24 are installed on the top of the two support bars. A discharge pipe is installed at one end of the lower part of the water tank 1, and a solenoid valve is installed on the discharge pipe. A magnet is installed at the top of the turntable 4, and the magnet is located at the center of the turntable 4.

[0026] Place the magnetic core to be deburred on top of the turntable 4, and then fix it with a magnet. When cleaning is required after the burrs are removed, the water pump can be started to draw water from the water tank 1 into the water outlet pipe 6, and then through the rotary joint to the drain pipe 7 and the spray head 8. Then the magnetic core and the top of the water tank 1 are cleaned. The cleaned water will carry the burr debris into the water inlet 13, and then into the water tank 1, where it will be filtered by the filter plate 24, thus achieving the effect of circulating water.

[0027] Example 2: Unlike Example 1, the rotating component can drive the drain pipe 7 to rotate, such as... Figure 3 and Figure 6 As shown, the rotating shaft 3 is provided with a rotating assembly for rotating the drain pipe 7. The rotating assembly includes a first bevel gear 9, which is located at one end of the rotating shaft 3. The first bevel gear 9 meshes with a second bevel gear 10, and the gear shaft of the second bevel gear 10 is connected to a rotating column. The rotating column is rotatably connected to the protective cover 5. One end of the drain pipe 7 and one end of the rotating column are provided with a first synchronous pulley 11, and a first synchronous belt 12 is provided between the two first synchronous pulleys 11.

[0028] When the drive motor is started and the rotating shaft 3 is rotated, the turntable 4 and the first bevel gear 9 will rotate, which in turn will drive the second bevel gear 10 and the rotating column to rotate. Then, under the action of the two first synchronous pulleys 11 and the first synchronous belt 12, the drain pipe 7 will rotate.

[0029] Example 3: Unlike Example 2, the polishing component can remove burrs from magnetic cores of different sizes, such as... Figures 1-3 , Figure 5 and Figure 6As shown, the top of the water tank 1 is equipped with a grinding assembly for deburring the magnetic core. The grinding assembly includes two movable columns 14, which are slidably connected to both ends of the top of the water tank 1 via two sliding plates. The outer surfaces of both movable columns 14 and the outer surface of the rotating shaft 3 are equipped with second synchronous pulleys 15. A second synchronous belt 16 is provided between the two second synchronous pulleys 15 on both sides. Each movable column 14 has a limiting sleeve at its top, and each limiting sleeve contains a grinding roller 17. The protective cover 5 is equipped with a moving assembly that drives the grinding roller 17 to move. The support frame 2 is equipped with an adjusting assembly that adjusts the tension of the second synchronous belt 16. The moving assembly includes two threaded rods 18, which are rotatably connected between the two ends of the protective cover 5 and the two ends of the support frame 2. The two threaded rods 18 are threadedly connected to the inside of the two sliding plates. The skateboards are all slidably connected to limit rods, and the two limit rods are respectively located between the two ends of the protective cover 5 and the two ends of the support frame 2. The adjustment assembly includes two first piston rods 19, which are respectively located at the two ends of the support frame 2. The two first piston rods 19 are slidably connected to second piston rods 20, and one end of each of the two second piston rods 20 is connected to one end of each of the two skateboards. The upper part of the support frame 2 is also provided with third piston rods 21 at both ends. Hollow tubes are provided between the two third piston rods 21 and the two first piston rods 19, and the two third piston rods 21 are slidably connected to fourth piston rods 22. One end of each of the two fourth piston rods 22 is provided with two connected sliders, and the top of each of the four sliders is provided with tensioning wheels 23. The sliders connected to the two fourth piston rods 22 are slidably connected to the two ends of the upper part of the support frame 2.

[0030] The magnetic core to be deburred is placed on turntable 4. Adjustments are made according to the different sizes of the magnetic cores. Two threaded rods 18 can be rotated, and under the action of two limiting rods, they drive two sliding plates to move, thereby changing the distance between the two limiting sleeves, the grinding roller 17, and the magnetic core. As the sliding plates gradually approach the support frame 2, they also drive two second piston rods 20 to move inside the first piston rod 19, compressing the air inside the first piston rod 19. This air is then discharged through a hollow tube into the third piston rod 21, pushing the fourth piston rod 22 to one end, thereby moving the slider and tension wheel 23, which in turn drives the two second synchronous belts 16 to adapt to the grinding roller 17 moving towards the turntable. The different distances between 4 are then used to start the drive motor, which drives the rotating shaft 3 to rotate. Then, under the action of the four second synchronous pulleys 15 and the two second synchronous belts 16, the two movable columns 14 and the grinding rollers 17 are driven to rotate, thereby grinding the magnetic core and removing burrs. The rotating shaft 3 only needs to rotate 180 degrees. The 180-degree rotation of the rotating shaft 3 will drive the turntable 4 to rotate 180 degrees. The turntable 4 is equipped with grinding rollers 17 on both sides, so the 180-degree rotation of the turntable 4 can achieve 360-degree grinding of the magnetic core. The 180-degree rotation of the rotating shaft 3 will also drive the first bevel gear 9 to rotate 180 degrees, thereby avoiding the contact between the water spray head 8 and the top of the inner part of the protective cover 5.
