Description

Technical Field

[0001] This disclosure belongs to the field of magnetic core polishing technology, and specifically relates to a through-type conveying device for double-sided polishing of magnetic cores. Background Technology

[0002] Magnetic cores are magnetic components made by sintering iron oxide with other metal oxides (such as manganese, zinc, and nickel), belonging to the category of soft magnetic ferrite materials. They are mainly divided into two types: manganese-zinc ferrites and nickel-zinc ferrites. Manganese-zinc ferrites have high permeability and low loss characteristics, making them suitable for low- to medium-frequency applications; nickel-zinc ferrites, due to their high resistivity, are suitable for high-frequency applications, with operating frequencies reaching hundreds of megahertz. Common structures include toroidal, E-shaped, and can-shaped cores. During production, magnetic cores require polishing to improve their quality and precision.

[0003] Chinese Patent Application No. 02266743.1 discloses a grinding machine suitable for machining soft magnetic ferrite parts, including a first conveying mechanism, a second conveying mechanism, a grinding device, and a grinding zone conveying device. The grinding device includes a reverse-axis permanent magnet chuck component and a reverse-axis component. The reverse-axis permanent magnet chuck component consists of a lifting mechanism and a permanent magnet chuck. The reverse-axis component consists of a motor, a spindle, a grinding wheel, and a housing. The end of the first conveying mechanism is adjacent to the reverse-axis permanent magnet chuck component. The grinding zone conveying device and the reverse-axis component are located below the permanent magnet chuck component. A second conveying mechanism is installed at the output position of the grinding zone conveying device. When used in conjunction with a linear pass-through grinding machine, the bottom and front surfaces of the workpiece can be machined in one operation, improving production efficiency.

[0004] Chinese Patent Application No. 202022272239.8 discloses a novel linear through-feed grinding machine, comprising a first conveyor belt and a second conveyor belt spaced at intervals on the same horizontal line, and a third conveyor belt positioned between the first and second conveyor belts. Strong magnetic tables are wound within the first, second, and third conveyor belts. The two ends of the third conveyor belt are respectively positioned above the first and second conveyor belts. A first flat grinding head is positioned above both the first and second conveyor belts, and a second flat grinding head is positioned between the first and second conveyor belts, below the third conveyor belt. At least one central column grinding head is also positioned above the first conveyor belt. This grinding machine uses the first flat grinding head and the second flat grinding head to grind the upper and lower end faces of the magnetic core, respectively, and the central column grinding head to grind the double central columns of the magnetic core. It features a high degree of automation, reduces labor costs, improves grinding efficiency, and achieves higher grinding accuracy, thus improving the quality of the magnetic core.

[0005] The aforementioned patents present several problems in practical applications, particularly when grinding large, flat magnetic cores using a pass-through grinder. To prevent the cores from becoming unsatisfactory in terms of flatness, the cores must not wobble during grinding. Therefore, the magnetic force of the strong magnetic chuck needs to be relatively large, causing the cores to shift before entering the grinding area of ​​the grinding wheel (i.e., the cores shift due to the magnetic force when moving from the non-magnetic area to the area of ​​the strong magnetic chuck). This shifting can cause the cores to collide with each other, resulting in defects such as chipped corners or cracked grinding surfaces.

[0006] Therefore, there is an urgent need for a through-type conveyor for double-sided grinding of magnetic cores, which uses an adjustable magnetic component to transition the magnetic core into a strong magnetic region, thus avoiding defects such as core chipping or cracking of the grinding surface caused by core movement. Utility Model Content

[0007] The purpose of this disclosure is to provide a through-feed conveyor for double-sided grinding of magnetic cores, thereby solving the problems mentioned in the background art. The through-feed conveyor provided in this disclosure has the characteristic of preventing magnetic core movement that could lead to chipped corners or cracked grinding surfaces.

[0008] To achieve the above objectives, this disclosure provides the following technical solution: a through-type conveyor for double-sided grinding of magnetic cores, comprising a first conveyor belt, a second conveyor belt, and a third conveyor belt arranged sequentially. The two ends of the second conveyor belt are respectively located above the ends of the first conveyor belt and the third conveyor belt. A second strong magnetic block corresponding to a first grinding head is installed inside the first conveyor belt, and a first strong magnetic block corresponding to a second grinding head is installed inside the second conveyor belt. An adjustable magnetic component is provided inside the first conveyor belt on the side of the second strong magnetic block near the incoming material. The adjustable magnetic component includes a connecting plate, a magnetic block is connected above the connecting plate, and an adjusting component for adjusting the height of the magnetic block is connected to the bottom of the connecting plate.

[0009] In this disclosure, the first strong magnetic block is mounted on the mounting frame of the second conveyor belt via a mounting plate, and the second strong magnetic block is mounted on the mounting frame of the first conveyor belt via a mounting plate.

[0010] To attach the magnetic core to the bottom surface of the second conveyor belt and transport it backward on the bottom surface of the second conveyor belt, a magnetic plate is further provided inside the second conveyor belt. The two sides of the magnetic plate are located above the ends of the first and third conveyor belts, respectively.

[0011] To adjust the distance between the magnetic block and the conveying surface of the first conveyor belt, the adjusting component is a miniature electric cylinder, and the connecting plate is installed on the output end of the miniature electric cylinder.

[0012] To adjust the distance between the magnetic block and the conveying surface of the first conveyor belt, the adjusting component further includes a mounting plate, wherein a connecting plate is connected to the mounting plate via at least two optical shafts, a wedge-shaped pad is provided above the mounting plate, and an inclined surface that mates with the wedge-shaped pad is provided at the bottom of the connecting plate. The optical shafts are connected to the mounting plate via linear bearings.

[0013] To increase the height of the internal space of the first conveyor belt and provide space for the installation of adjustment components, two tensioning shafts are further provided on the first conveyor belt.

[0014] To facilitate adjustment of the pads, the two sides of the mounting frame of the first conveyor belt are further designed with a hollow structure.

[0015] To further polish the cylindrical surface of the magnetic core, a third grinding head is provided above the third conveyor belt, and the structure of the third conveyor belt is the same as that of the first conveyor belt.

[0016] Compared with the prior art, the beneficial effects of this disclosure are:

[0017] 1. The present invention provides an adjustable magnetic component inside the first conveyor belt on the side of the second strong magnetic block near the incoming material. The magnetic block increases the frictional resistance between the magnetic core to be ground and the conveying surface of the first conveyor belt, preventing the magnetic core to be ground from moving under the action of the second strong magnetic block and colliding with the magnetic core being ground, which would cause corner chipping or cracking.

[0018] 2. This disclosure adjusts the distance between the magnetic block and the conveying surface of the first conveyor belt by adjusting the adjustment component, thereby adjusting the magnetic attraction force of the magnetic block on the magnetic core to be ground, thereby adjusting the frictional resistance between the magnetic core and the conveying surface of the first conveyor belt, avoiding slippage between the magnetic core and the first conveyor belt, and thus extending the service life of the conveyor belt.

[0019] 3. The second conveyor belt of this disclosure is also provided with a magnetic plate inside. The magnetic plate is less magnetic than the first strong magnetic block. The two sides of the magnetic plate are located above the ends of the first conveyor belt and the third conveyor belt, respectively. The magnetic plate attracts the magnetic core to the bottom surface of the second conveyor belt, so that the magnetic core is transported backward on the bottom surface of the second conveyor belt.

[0020] 4. The first conveyor belt of this disclosure is provided with two tensioning shafts, which increases the height of the internal space of the first conveyor belt and provides space for the installation of adjustment components.

[0021] 5. A third grinding head is provided above the third conveyor belt of this disclosure. The structure of the third conveyor belt is the same as that of the first conveyor belt. The third grinding head is used to grind the cylindrical surface of the magnetic core. Attached Figure Description
