[0002] A magnetic ring is a ring-shaped magnetic conductor that has a good effect on suppressing high-frequency noise and is widely used in electronic circuits. During the manufacturing process of existing magnetic rings, burrs generally exist on the outer surface. Therefore, after the magnetic ring is cut and formed, it needs to be polished to remove the burrs.

[0003] At present, the sizes of magnetic rings used in different usage scenarios are different. For cost considerations, the same magnetic ring grinding device needs to be able to adapt to the grinding of magnetic rings of different specifications. Usually, the magnetic ring burr grinding devices used in the market are equipped with multiple clamping die heads of different specifications. Firstly, before grinding, it is necessary to spend a certain amount of time to find a matching clamping die head according to the specifications of the magnetic ring; secondly, after finding a matching clamping die head, it is necessary to spend some time to replace the original clamping die head, which is inconvenient and inefficient. At the same time, the magnetic ring will produce a lot of residues during the grinding process, and the residues fall everywhere, which is troublesome for the staff to clean up.

[0036] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example

[0037] See also Figure 1 or Figure 2 or Figure 4 As shown, this embodiment provides a magnetic ring burr grinding device, which includes a supporting box 1, a grinding head 14 and a clamping assembly.

[0038] The grinding head 14 is arranged in the supporting box 1 and is used for performing a grinding operation on the burrs of the magnetic ring.

[0039] The clamping assembly is arranged in the support box 1 and is used to clamp the magnetic ring. The clamping assembly includes a motor 3, a square block 4 and a clamping plate 6. The motor 3 is arranged on the side wall of the support box 1. The working end of the motor 3 passes through the side wall of the support box 1 and is connected to a connecting rod 2. The square block 4 is connected to one end of the connecting rod 2. A telescopic mechanism is arranged on the square block 4. The clamping plate 6 has an outer shape surface adapted to the magnetic ring, and is arranged at the working end of the telescopic mechanism.

[0040] The magnetic ring burr grinding device pushes the clamping plate 6 outward through the telescopic mechanism of the square block, so that the inner wall of the magnetic ring is clamped with the clamping plate 6 that continuously exerts force outward and is not easy to fall off from the clamping assembly. Therefore, the telescopic mechanism can be adjusted to push the clamping plate 6 outward to a distance, so that magnetic rings with different inner wall sizes can be clamped in the clamping assembly for subsequent grinding. The method of grinding the magnetic ring is: the motor 3 drives the magnetic ring clamped in the clamping plate 6 to rotate, and rubs with the grinding head 14 to achieve grinding of the magnetic ring.

[0041] Specifically,

[0042] The grinding head 14 is externally connected to a power source. The grinding head 14 is electrically driven and can be retracted and arranged in the supporting box 1. When the bottom of the magnetic ring contacts the grinding head 14, the inner wall of the grinding head 14 rubs against the surface of the magnetic ring, thereby achieving the effect of grinding the magnetic ring.

[0043] The clamping assembly is arranged in the supporting box 1 and is used for clamping the magnetic ring. The clamping assembly comprises a motor 3, a square block 4 and a clamping plate 6.

[0044] The motor 3 is installed on the side wall of the supporting box 1. The working end of the motor 3 passes through the side wall of the supporting box 1 and is connected to a connecting rod 2. When the motor 3 is started, the motor 3 can drive the connecting rod 2 to rotate.

[0045] The square block 4 is connected to one end of the connecting rod 2. A telescopic mechanism is provided on the square block 4. The telescopic mechanism is a cylinder 5. There are two cylinders 5. The two cylinders 5 are respectively arranged on the upper wall surface and the lower wall surface of the square block 4. The square block 4 can be driven to rotate by the motor 3.

[0046] The clamping plate 6 is provided to match the cylinder 5. That is, the clamping plate 6 not only has an outer shape surface adapted to the magnetic ring, but also the number of the clamping plates 6 is the same as the cylinder 5. Each clamping plate 6 is fixed to the working end of each cylinder 5. The two cylinders 5 are controlled to be driven synchronously, and each cylinder 5 pushes the corresponding clamping plate 6 to move outward, so that the inner wall of the magnetic ring is clamped with the clamping plate 6 that continuously exerts force outward and is not easy to fall off from the clamping assembly. By adjusting the distance that the two cylinders 5 push the corresponding clamping plates 6 outward, magnetic rings with different inner wall sizes can be clamped in the clamping assembly. In addition, the clamping plate 6 can be driven to rotate by the motor 3, thereby driving the magnetic ring clamped by it to rotate. The magnetic ring contacts the grinding head 14 under the condition of rotation, and can be rubbed on the surface of the grinding head 14 for grinding.

[0047] By adjusting the distance of the two cylinders 5 to push the corresponding clamping plates 6 outward, the requirements of different specifications of magnetic rings being clamped by a clamping assembly can be met. After the clamping assembly clamps the magnetic ring, the motor 3 drives the magnetic ring clamped on the clamping plate 6 to rotate, and rubs against the grinding head 14 to achieve grinding of the magnetic ring. The retractable setting of the grinding head 14 ensures the grinding effect during the grinding of magnetic rings of different specifications. Example

[0048] Based on Example 1, refer to Figure 2 In order to increase the stability of the square block 4 during the rotation process and reduce the shaking of the square block 4, the clamping assembly also includes a telescopic member and a bearing 13.

[0049] The telescopic member is arranged on one side of the square block 4 relative to the connecting rod 2. The telescopic member is a hydraulic rod 12. When the magnetic ring is clamped by the clamping assembly, the hydraulic rod 12 abuts against the square block 4.

[0050] The bearing 13 is mounted on the inner wall of the supporting box 1. One end of the hydraulic rod 12 is rotatably connected in the bearing 13, so that the hydraulic rod 12 can maintain stable rotation. Example

[0051] Based on Example 1, refer to Figure 1 or Figure 3-Figure 4The magnetic ring burr grinding device also includes a collecting and protecting component. The collecting and protecting component includes a rectangular frame 7, a collecting box 8, a square frame 10 and a transparent protecting plate 11.

[0052] The rectangular frame 7 has an inclined blanking opening for receiving the burrs after grinding. The rectangular frame 7 is movably plugged into the supporting box body 1. The collecting box 8 is used to collect the residue. One side of the collecting box 8 is snapped into the rectangular frame 7, and the collecting box 8 is installed on the supporting box body 1 through the rectangular frame 7. A handle 9 is provided on the other side of the collecting box 8. The residue on the surface of the polished magnetic ring falls into the collecting box 8 in the rectangular frame 7. The collecting box 8 is taken out by manually pulling the handle 9, and the residue in the collecting box 8 is cleaned up uniformly. The square frame 10 is fixedly connected to the top of the rectangular frame 7. The transparent protective plate 11 is fixedly connected to the inner wall of the square frame 10. The transparent protective plate 11 is installed on the supporting box body 1 through the square frame 10. The transparent protective plate 11 can block the residue in the process of grinding the magnetic ring and fall into the collecting box 8 to prevent the above-mentioned residue from splashing outside the supporting box body 1, thereby achieving the purpose of collecting residue and protection. Example

[0053] Based on Example 1, refer to Figure 1 or Figure 3-Figure 4 The magnetic ring burr grinding device also includes a placement frame 17. The placement frame 17 is arranged on the outer side wall of the supporting box 1 for placing the polished magnetic ring. Example

[0054] Based on Example 1, refer to Figure 1 The four corners of the bottom of the supporting box body 1 are provided with fixing grooves. A roller 15 is fixedly connected to the inner wall of the fixing groove. A hand-held handle 16 is provided on the side wall of the supporting box body 1.

[0055] The staff holds the handle 16 to push the magnetic ring burr grinding device, and the device can be moved to a designated position under the action of the roller 15, which is very convenient.
