Description

Technical Field

[0001] This utility model belongs to the technical field of magnetic core grinding devices, and specifically relates to a magnetic core burr grinding device. Background Technology

[0002] Magnetic cores, as key components in electronic devices, are widely used in transformers, inductors, and other equipment. During the manufacturing process of magnetic cores, limitations in cutting and stamping processes often result in varying degrees of burrs on the core surface. These burrs not only affect the appearance quality of the core but can also cause degradation in electromagnetic performance, assembly difficulties, and reliability issues. Therefore, it is necessary to polish the magnetic core. However, existing polishing equipment makes core removal inconvenient, requiring manual removal, resulting in high difficulty and low efficiency in core removal. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic core burr grinding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a magnetic core burr grinding device, comprising a housing, an inner barrel installed inside the housing, the top of the inner barrel being open to form a cavity for accommodating steel needles and magnetic cores, and the bottom of the inner barrel being open to form a discharge hole communicating with the cavity, a filter screen being installed inside the discharge hole, a plug being provided inside the housing that moves up and down relative to the inner barrel, the plug being located below the inner barrel, a discharge trough being open on one side of the housing to form a discharge trough communicating with its own interior, the discharge trough being located below the discharge hole, a turntable being rotatably connected inside the housing, the turntable being located below the plug, and an electromagnet being fixedly connected to the top of the turntable.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) This utility model moves the plug to block the discharge hole of the inner barrel. After the magnetic core is ground inside the inner barrel, the plug moves away from the discharge hole, so that the ground magnetic core is discharged through the discharge hole and discharged through the discharge trough. There is no need for manual removal of the ground magnetic core, which reduces the difficulty of removing the magnetic core and improves the removal efficiency of the magnetic core.

[0018] 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.

[0019] Please see Figures 1-4 As shown, this utility model provides the following technical solution:

[0020] A magnetic core burr grinding device includes a housing, an inner barrel 7 installed inside the housing, the top of the inner barrel 7 being open to form a cavity for accommodating steel needles and magnetic cores, and the bottom of the inner barrel 7 being open to form a discharge hole 8 communicating with the cavity, a filter screen being installed inside the discharge hole 8, a plug 11 being provided inside the housing that moves up and down relative to the inner barrel 7, the plug 11 being located below the inner barrel 7, a discharge trough 5 being open on one side of the housing and communicating with its own interior, the discharge trough 5 being located below the discharge hole 8, a turntable 14 being rotatably connected inside the housing, the turntable 14 being located below the plug 11, and an electromagnet 15 being fixedly connected to the top of the turntable 14.

[0021] With the above technical solution, when personnel need to grind the magnetic core, the magnetic core to be ground is added to the cavity of the inner barrel 7, and then a steel needle is placed inside the cavity. After the magnetic core is added, the plug 11 is moved to block the discharge hole 8. The turntable 14 rotates and the electromagnet 15 is energized, so that the steel needle inside the cavity rotates continuously under the action of the electromagnet 15. The steel needle grinds the magnetic core and removes the burrs on the magnetic core. After the magnetic core is ground, the plug 11 moves down until the plug 11 is completely separated from the discharge hole 8. The turntable 14 stops rotating, and the ground magnetic core is discharged through the discharge hole 8. The steel needle is blocked from being discharged from the cavity by the filter screen. After the steel core is ground, the ground magnetic core is discharged through the discharge trough 5.

[0022] To guide the polished magnetic core, such as Figures 2-4 As shown, a guide cover 13 is also fixedly connected inside the housing. The bottom of the guide cover 13 is open to form a bottom groove. The guide cover 13 is located below the plug 11, and the turntable 14 is located inside the bottom groove.

[0023] In this embodiment, when the ground magnetic core is discharged from the discharge hole 8, the magnetic core is guided by the guide cover 13, so that the magnetic core slides down from the guide cover 13, making it easy to collect the magnetic core.

[0024] Furthermore, regarding how the plug 11 moves in this utility model, as follows: Figures 3-4 As shown, an electric push rod 12 is fixedly connected to the top of the guide cover 13, and the telescopic end of the electric push rod 12 is fixedly connected to the bottom of the plug 11.

[0025] In this embodiment, when it is necessary to move the plug 11, the electric push rod 12 is operated to move the plug 11, so that the plug 11 blocks the discharge hole 8 or separates the plug 11 from the discharge hole 8.

[0026] Furthermore, regarding how turntable 14 rotates, as follows: Figures 3-4 As shown, a motor 10 is fixedly connected inside the bottom trough. The output end of the motor 10 is fixedly connected to the bottom of the turntable 14, and the motor 10 is fixedly connected inside the guide cover 13.

[0027] In this embodiment, when it is necessary to drive the turntable 14 to rotate, the motor 10 works, thereby driving the turntable 14 to rotate, which in turn drives the electromagnet 15 to rotate.

[0028] Specifically, in one embodiment, regarding the aforementioned housing component, such as Figures 1-4 As shown, the housing component includes an outer shell 1, with one side of the outer shell 1 open to form a side groove 6, a discharge groove 5 formed on one side of the outer shell 1 and located below the side groove 6, a cabinet door 3 for covering the side groove 6 is rotatably connected to one side of the outer shell 1, a handle 4 is fixedly connected to the outside of the cabinet door 3, and a foot 2 is fixedly connected to the bottom of the outer shell 1.

[0029] In this embodiment, the outer shell 1 is supported by the base 2. When the magnetic core needs to be processed, the cabinet door 3 is pulled by the handle 4, which makes the cabinet door 3 rotate around the outer shell 1, thereby exposing the side groove 6. The magnetic core is then added into the inner barrel 7 through the side groove 6. After the magnetic core is added, the cabinet door 3 is closed, and the magnetic core processing can be carried out.

[0030] When the device discharges the magnetic core, in order to improve the core discharge efficiency, such as Figures 3-4 As shown, a ramp 9 is formed at the bottom of the inner part of the outer casing 1, and the horizontal height of the ramp 9 on the side near the discharge chute 5 is lower than the horizontal height on the other side.

[0031] In this embodiment, when the magnetic core is discharged through the discharge chute 5, the ramp 9 is used to make the discharge of the magnetic core more efficient.

[0032] 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.
