Description

Technical Field

[0001] This utility model relates to the field of integrated deburring technology for magnetic cores, specifically to an integrated device for rapid deburring of magnetic cores. Background Technology

[0002] The integrated deburring device for magnetic core processing is an automated device specifically designed for removing surface or edge burrs from magnetic cores made of magnetic materials (such as ferrite, silicon steel sheets, etc.) after processing. The device integrates multiple functional modules to complete the deburring operation. It is a mechanical device specifically designed for the post-processing stage in the magnetic core manufacturing process and typically includes: a feeding system, a positioning and clamping mechanism, a deburring execution unit, a dust collection / chip removal system, and a material unloading or conveying system. The overall design emphasizes "integration" and "speed," meaning that all deburring operations are completed in one station or continuous process without manual intervention or multiple transfers.

[0003] Common deburring devices for magnetic core processing often employ mechanical brushing, belt sanding, or pneumatic blowing. These methods are effective in removing burrs from conventional outer surfaces, but they have significant limitations when dealing with complex geometric structures such as microholes, narrow slits, internal chamfers, and cross grooves on the magnetic core. Due to the size and rigidity limitations of the mechanical tools, their working heads cannot easily enter hidden areas with shallow depths or narrow channels, resulting in the inability to effectively contact and remove burrs in these areas. Residual burrs not only affect the assembly accuracy of the magnetic core but may also scratch the enameled wire during subsequent winding, causing short circuits or insulation failure.

[0004] Furthermore, magnetic core materials such as ferrite, amorphous alloys, or nanocrystals generally have the characteristics of high brittleness, high hardness, and easy edge chipping. During dry deburring, high-speed friction or impact can easily generate fine debris and dust. Most traditional devices are open or semi-closed structures, lacking effective dust control measures, resulting in a large amount of dust escaping into the workshop environment during processing. This not only pollutes the work space and endangers the health of operators, but may also affect the quality of subsequent processes due to dust adhering to the surface of the magnetic core. More seriously, the fine particles generated by materials such as ferrite have strong adsorption and conductivity. If they are not removed in time, they may accumulate inside the equipment, causing electrical faults or reducing the equipment's lifespan.

[0005] Therefore, existing deburring devices are significantly inadequate in terms of both adaptability to complex structures and dust suppression capabilities, making it difficult to meet the requirements of high-precision and high-cleanliness magnetic core manufacturing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an integrated device for rapid deburring of magnetic cores. Ultrasonic and micro-abrasive work together to remove burrs deep into crevices, while a sealed wet chamber suppresses dust. It is suitable for brittle magnetic cores such as ferrite cores, balancing cleanliness and high efficiency. It solves the problems of common deburring devices that have difficulty handling micro-holes and narrow crevices, and the high dust levels caused by dry operations, which cannot meet the cleanliness and structural adaptability requirements of precision magnetic cores.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated rapid deburring device for magnetic core processing, comprising a deburring processing box; further comprising a sealing cover rotatably connected to the upper end of the deburring processing box, the lower end face of the sealing cover being provided with a sealing ring, the deburring processing box being provided with a partition, the partition dividing the deburring processing box into an upper cavity and a lower cavity, the lower cavity being used to accommodate a transmission structure; a motor is installed on the lower end face of the deburring processing box, the output end of the motor is connected to a drive gear through a connecting rod, a rotating rod is rotatably connected to the bottom surface inside the deburring processing box, a driven gear is provided on the outer side of the rotating rod, the driven gear meshes with the drive gear, a rotating disk is connected to the upper end of the rotating rod, a fixed disk is detachably installed on the upper end of the rotating disk, and a placement rack arranged in a ring array is provided on the upper end of the fixed disk;

[0008] An ultrasonic generator is installed on the front surface of the deburring processing box. Two ultrasonic transducers are provided on the upper surface of the partition, and the ultrasonic transducers are electrically connected to the ultrasonic generator. A liquid storage tank is provided on the left end of the deburring processing box. A delivery pump is installed on the upper end of the liquid storage tank. The output end of the delivery pump is connected to the injection head located on the lower end of the sealing cover through a delivery hose. A drain port is provided on the partition. A pump body is installed on the lower end of the liquid storage tank. The output end of the pump body is connected to the drain port through a discharge hose.

[0009] Furthermore, the sealing cover is rotatably connected to the upper end of the deburring box via a hinge or rotating shaft, and when the sealing cover is closed, it forms a sealing fit with the upper port of the deburring box through a sealing ring.

[0010] Furthermore, the rotating disk and the fixed disk are connected by bolts for easy replacement of the fixed disk to accommodate magnetic cores of different specifications.

[0011] Furthermore, the placement rack is an upward-protruding columnar ring structure with a baffle at the top for limiting the magnetic core, and multiple placement racks are distributed at equal intervals along the circumference of the fixed disk.

[0012] Furthermore, the ultrasonic transducer is embedded on the upper surface of the partition plate and located on both sides below the rotating disk, with its vibration direction facing the area where the magnetic core is located in the upper cavity.

[0013] Furthermore, both the delivery hose and the discharge hose are corrosion-resistant flexible pipes, and the injection head is located in the center area of ​​the lower end face of the sealing cap, used to uniformly inject the micro-abrasive suspension into the upper cavity.

[0014] Furthermore, a filter screen is installed at the drain port on the partition, and the pump body draws the used liquid from the upper cavity back to the storage tank for circulation through the discharge hose.

[0015] Furthermore, a vacuum connector is provided on the sealing cover. The vacuum connector passes through the sealing cover and communicates with the upper cavity, and is used to connect an external vacuum machine to evacuate the inside of the deburring processing box.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] 1. The ultrasonic transducer excites high-frequency vibration in the upper cavity, causing the injected micro-abrasive suspension to produce a cavitation effect. When the cavitation bubbles collapse, the local impact force released and the micro-abrasive particles work together on the surface of the magnetic core. The two work together to effectively enter complex structural areas such as micropores and narrow slits, achieving efficient removal of burrs in hidden areas.

[0018] 2. The entire deburring process is carried out in a closed wet chamber consisting of a sealing cover, sealing ring and partition. The dust generated during the process is encapsulated by the liquid medium and discharged with the circulating liquid, effectively suppressing dust flying. It is especially suitable for brittle magnetic core materials such as ferrite that are fragile and prone to producing fine particles, ensuring a clean working environment and product integrity.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-5 This embodiment of a rapid deburring integrated device for magnetic core processing includes a deburring processing box 1; it also includes a sealing cover 2 rotatably connected to the upper end of the deburring processing box 1, and a sealing ring 3 provided on the lower end face of the sealing cover 2. The deburring processing box 1 is provided with a partition 4, which divides the deburring processing box 1 into an upper cavity and a lower cavity. The lower cavity is used to accommodate the transmission structure. A motor 10 is installed on the lower end face of the deburring processing box 1. The output end of the motor 10 is connected to a drive gear 11 through a connecting rod. A rotating rod 5 is rotatably connected to the bottom surface inside the deburring processing box 1. A driven gear 6 is provided on the outer side of the rotating rod 5. The driven gear 6 meshes with the drive gear 11. A rotating disk 7 is connected to the upper end of the rotating rod 5. A fixed disk 8 is detachably installed on the upper end of the rotating disk 7. A placement rack 9 arranged in a ring array is provided on the upper end of the fixed disk 8.

[0027] In this embodiment, the ultrasonic transducer 20 excites the micro-abrasive suspension to generate a cavitation effect. Its impact force and the synergistic effect of the abrasive can penetrate deep into the narrow gaps of micropores to efficiently remove hidden burrs. At the same time, it operates in a closed wet cavity formed by the sealing cover 2, the sealing ring 3 and the partition 4. The dust is wrapped by the liquid and discharged with the circulating liquid, which effectively suppresses dust. It is especially suitable for brittle magnetic cores such as ferrite, and takes into account both the deburring effect and environmental cleanliness.

[0028] Please see Figures 1-4 In this embodiment, in order to efficiently remove hidden burrs by penetrating deep into the tiny gaps of the magnetic core, an ultrasonic generator 19 is installed on the front surface of the deburring processing box 1. Two ultrasonic transducers 20 are provided on the upper surface of the partition 4, and the ultrasonic transducers 20 are electrically connected to the ultrasonic generator 19. A liquid storage tank 13 is provided on the left end of the deburring processing box 1. A delivery pump 14 is installed on the upper surface of the liquid storage tank 13. The output end of the delivery pump 14 is connected to the injection head 16 located on the lower end of the sealing cover 2 through a delivery hose 15. A drain port is provided on the partition 4. A pump body 17 is installed on the lower end of the liquid storage tank 13. The output end of the pump body 17 is connected to the drain port through a discharge hose 18.

[0029] In this embodiment, the ultrasonic generator 19 provides high-frequency electrical energy to the ultrasonic transducer 20, causing the micro-abrasive suspension to generate a cavitation effect, enhancing the ability to remove burrs from the fine gaps in the magnetic core. The storage tank 13 is used to store the micro-abrasive suspension. The delivery pump 14 injects the liquid into the processing chamber through the injection head 16 to form a wet environment. The pump body 17 draws the used liquid back from the chamber through the discharge hose 18 and returns it to the storage tank 13 through the discharge port for recycling. This reduces consumable consumption and effectively suppresses dust generation while efficiently deburring.

[0030] It should be noted that the rotating disk 7 and the fixed disk 8 are detachably connected by bolts to facilitate the replacement of the fixed disk 8 with different specifications of magnetic cores. The ultrasonic transducer 20 is embedded on the upper end face of the partition plate 4 and located on both sides below the rotating disk 7. Its vibration direction is towards the area where the magnetic core is located in the upper cavity. The rotating disk 7 and the fixed disk 8 are detachably connected by bolts, which facilitates the quick replacement of the fixed disk 8 with different specifications of magnetic cores, improves the versatility and changeover efficiency of the equipment. The ultrasonic transducer 20 is installed on the upper end face of the partition plate 4 and faces the magnetic core area. It is used to generate high-frequency vibration to excite cavitation effect during processing, which enhances the removal effect on the surface and edge burrs of the magnetic core.

[0031] Please see Figures 1-5 In this embodiment, in order to effectively lock in dust and prevent it from flying, especially suitable for fragile ferrite cores, and to keep the environment clean and the product intact, the sealing cover 2 in this embodiment is rotatably connected to the upper end of the deburring processing box 1 through a hinge or rotating shaft. When the sealing cover 2 is closed, it forms a sealed fit with the upper port of the deburring processing box 1 through the sealing ring 3. The placement rack 9 is an upwardly protruding columnar annular structure with a baffle for limiting the magnetic core on its top. Multiple placement racks 9 are evenly distributed around the fixed disk 8. The sealing cover 2 is provided with a vacuum connector 12, which penetrates the sealing cover 2 and communicates with the upper cavity for connecting an external vacuum machine to evacuate the inside of the deburring processing box 1.

[0032] In this embodiment, the sealing cover 2 is opened and closed by a hinge or a rotating shaft. When closed, it relies on the sealing ring 3 to form a sealed cavity with the box body, effectively preventing dust from escaping. The vacuum connector 12 connects to an external vacuum machine to evacuate the cavity, further suppressing dust diffusion and enhancing the cavitation effect. The placement rack 9 adopts a columnar ring structure with a baffle to stably limit the magnetic core and avoid displacement or collision during processing. The overall structure is particularly suitable for fragile ferrite magnetic cores, ensuring product integrity and maintaining a clean working environment.

[0033] It should be noted that both the delivery hose 15 and the discharge hose 18 are corrosion-resistant flexible pipes, and the injection head 16 is located in the center area of ​​the lower end face of the sealing cover 2, which is used to uniformly inject the micro-abrasive suspension into the upper cavity. The discharge port on the partition 4 is equipped with a filter screen. The pump body 17 draws the used liquid from the upper cavity back to the storage tank 13 for circulation through the discharge hose 18.

[0034] The working principle of the above embodiments is as follows:

[0035] In use, the magnetic core to be processed is first placed in the placement rack 9 on the fixed plate 8. The baffle at the top of the placement rack 9 limits the magnetic core to prevent it from shifting or colliding during processing. Then the sealing cover 2 is closed. The sealing cover 2 is rotated to the closed position by a hinge or rotating shaft, and relies on the sealing ring 3 on the lower end face to fit tightly with the upper port of the deburring processing box 1 to form a sealed upper cavity.

[0036] Next, an external vacuum machine is connected through the vacuum connector 12 on the sealing cover 2 to evacuate the inside of the upper cavity, reduce the air pressure inside the cavity, provide favorable conditions for subsequent ultrasonic cavitation, and at the same time reduce bubble interference and improve cavitation intensity.

[0037] Subsequently, the micro-abrasive suspension in the storage tank 13 is transported to the injection head 16 on the lower end face of the sealing cover 2 by the delivery pump 14 through the delivery hose 15, and is evenly injected into the upper cavity from the injection head 16, so that the magnetic core is completely immersed in the liquid environment, forming wet deburring conditions.

[0038] At this time, the ultrasonic generator 19 installed on the front side of the deburring processing box 1 is started, providing high-frequency electrical energy to the two ultrasonic transducers 20 on the upper end face of the partition 4. The ultrasonic transducers 20 generate high-frequency vibration, which excites the micro-abrasive suspension to generate cavitation effect. When the cavitation bubbles collapse, they release local impact force, which works in synergy with the micro-abrasive particles to penetrate deep into the micropores, narrow gaps and hidden edge areas of the magnetic core, and efficiently remove burrs.

[0039] At the same time, the motor 10 at the lower end of the deburring processing box 1 starts, and drives the drive gear 11 to rotate through the connecting rod. The drive gear 11 meshes with the driven gear 6, driving the rotating rod 5 and the rotating disk 7 above to rotate slowly. The fixed disk 8 rotates synchronously with the rotating disk 7, so that the magnetic cores on each placement rack 9 move at a uniform speed in the cavity, ensuring that all surfaces are uniformly subjected to ultrasonic and abrasive action, and improving the consistency of deburring.

[0040] After deburring is completed, the pump body 17 is started, and the used suspension is drawn from the upper cavity through the discharge hose 18 and the discharge port on the partition 4. The discharge port is equipped with a filter screen to intercept large particles of impurities. The liquid returns to the storage tank 13 and is filtered and settled to achieve recycling, reducing the waste of consumables.

[0041] Finally, open the sealing cover 2 and take out the deburred magnetic core. The whole process is completed in a closed wet environment. The dust is wrapped in liquid and discharged with the circulating liquid, which effectively suppresses dust. It is especially suitable for brittle magnetic cores such as ferrite, which not only ensures the integrity of the product, but also maintains a clean working environment.

[0042] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.

[0043] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
