Description

Technical Field

[0001] This application relates to the field of magnetic core manufacturing technology, and in particular to a grinding apparatus for magnetic core manufacturing. Background Technology

[0002] A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. The magnetic core includes a base plate, side legs, and a center post. The side legs are located on both sides of the base plate, and the center post is located in the middle of the base plate. The upper surface of the center post is lower than the upper surface of the side legs, and a winding cavity that can accommodate a coil is formed between the side legs and the center post.

[0003] In the production process of magnetic cores, high-temperature sintering is required. During sintering, factors such as the magnetic powder formula, pressing density, and kiln sintering atmosphere often lead to defects such as core deformation and unevenness at the bottom after sintering. Because magnetic core products have strict dimensional accuracy requirements, they must be ground on a grinding machine before being finished. During grinding, the edges are usually ground flat first, followed by the central column, requiring two grinding operations. This is cumbersome, time-consuming, and reduces work efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation, connection, and linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] Reference Figures 1 to 3 This application provides a grinding apparatus for producing magnetic cores, including: a base 100; a conveying mechanism 200 disposed on the base 100 for conveying magnetic cores; and a grinding mechanism including a lifting assembly 310, a rotating assembly 320, and a grinding wheel 330. The lifting assembly 310 is disposed on the base 100, the rotating assembly 320 is disposed on the lifting assembly 310, and the grinding wheel 330 is connected to the rotating assembly 320 and located above the conveying mechanism 200. The grinding wheel 330 has a first grinding surface 340 and a second grinding surface 350. The first grinding surface 340 is located at both ends of the grinding wheel 330 and is used to grind the edge leg. The second grinding surface 350 is disposed between the first grinding surfaces 340. The diameter of the second grinding surface 350 is larger than the diameter of the first grinding surface 340 and is used to grind the central column. The control mechanism includes a sensor 400 and a controller. The sensor 400 is used to sense the magnetic core. The sensor 400 is connected to the conveying mechanism 200 and the grinding mechanism respectively. The controller is connected to the sensor 400, the conveying mechanism 200 and the grinding mechanism respectively.

[0028] During operation, the conveying mechanism 200 transports the magnetic core to the grinding mechanism. Then, the sensor 400 detects that the magnetic core has reached the grinding position, at which point the conveying mechanism 200 stops transporting, and the grinding mechanism begins operation. The rotating component 320 drives the grinding wheel 330 to rotate, and the lifting component 310 lowers the grinding wheel 330, bringing it closer to the magnetic core, thus achieving the grinding of the magnetic core. By simultaneously setting the first grinding surface 340 and the second grinding surface 350 on the grinding wheel 330, the grinding wheel 330 can perform grinding of the side legs and the central column in one pass, shortening grinding time and improving work efficiency.

[0029] The length of the second grinding surface 350 is greater than the diameter of the central column and less than the distance between the first grinding surfaces 340. This ensures grinding of the central column while avoiding friction between the grinding wheel 330 and the side wall of the side leg, thus improving grinding quality and ensuring product quality.

[0030] Reference Figure 1 and Figure 2 In this embodiment, the conveying mechanism 200 includes a conveyor belt 210 and limiting plates 220. The conveyor belt 210 is disposed on the machine base 100 for conveying the magnetic core, and the limiting plates 220 are disposed on both sides of the conveyor belt 210 to limit the lateral displacement of the magnetic core. By setting the limiting plates 220 on both sides of the conveyor belt 210 to limit the lateral displacement of the magnetic core, the stability of the magnetic core conveying is ensured, thereby improving the grinding quality. Further, the machine base 100 is provided with a fixing frame 230, which is located on both sides of the conveyor belt 210, and the limiting plates 220 are slidably disposed on the fixing frame 230. By using the sliding arrangement of the limiting plates 220, the distance between the limiting plates 220 can be adjusted to accommodate magnetic cores of different specifications, thus expanding the applicable range. Specifically, the fixing frame 230 is provided with a strip-shaped hole, and the limiting plates 220 are connected to the adjusting hole by adjusting screws, resulting in a simple structure and easy operation. Of course, multiple fixing holes can be used instead of strip holes, and this application does not restrict this.

[0031] As can be conceived, the machine base 100 includes a column 110, which is located on one side of the conveying mechanism 200, and a lifting assembly 310 is located on the column 110. The lifting assembly 310 includes a cylinder and a mounting base. The cylinder is located on the column 110, and the mounting base is connected to the telescopic end of the cylinder. A rotating assembly 320 is located on the mounting base. The height adjustment of the grinding wheel 330 is achieved through the cylinder, resulting in a simple structure and stable operation.

[0032] It should be noted that the cylinder can also be implemented by a motor and a lead screw and nut, or by a motor and a gear and rack. Those skilled in the art can make a reasonable choice according to the actual situation, and this application does not limit it.

[0033] As is readily understood, the rotating assembly 320 includes a motor and a rotating shaft. The motor is mounted on the lifting assembly 310, and the rotating shaft is connected to the motor. The grinding wheel 330 is mounted on the rotating shaft. The motor drives the rotating shaft to rotate, thereby rotating the grinding wheel 330 and allowing the grinding wheel 330 to grind the magnetic core. The structure is simple and the operation is convenient. The motor and the rotating shaft can be directly connected via a coupling or via a gear set, as long as the rotation of the grinding wheel 330 to grind the magnetic core is achieved. This application does not impose any limitations on this.

[0034] Reference Figure 1 and Figure 2 Optionally, the base 100 is provided with a bracket 120, and the sensor 400 is adjustablely mounted on the bracket 120. The sensor 400 can be adjusted both horizontally and vertically. By making the sensor 400 adjustable, its position can be adjusted, thereby expanding its applicability and reducing production costs.

[0035] Optionally, the base 100 is equipped with a protective cover 130, and the grinding mechanism is located inside the protective cover 130. In this case, the dust generated during grinding is confined within the protective cover 130, reducing pollution of the working environment and improving work safety. Furthermore, the grinding device for core production also includes a dust removal mechanism 500, which includes a dust removal pipe 510 and a dust removal fan 520. The dust removal pipe 510 is located on the base 100, with its opening facing the core. The dust removal fan 520 is connected to the dust removal pipe 510 and is also connected to the sensor 400 and the controller. When the sensor 400 detects the core, the conveying mechanism 200 stops working, the grinding mechanism begins grinding, and simultaneously the dust removal fan 520 operates to generate negative pressure, causing the dust removal pipe 510 to absorb the dust generated during grinding, thereby achieving dust removal and improving work stability and safety.
