Description

Technical Field

[0001] This invention belongs to the field of magnetic core production technology, specifically a grinding table for magnetic core production. Background Technology

[0002] In modern electronics industry, magnetic cores are key components of various electromagnetic elements such as inductors and transformers. Their performance and precision play a crucial role in the operational stability and efficiency of the entire electronic device. With the continuous development of electronic technology, the quality requirements for magnetic cores are becoming increasingly stringent.

[0003] Magnetic cores are typically made of magnetic materials such as ferrite, iron powder cores, and amorphous alloys. During their production, after the forming process, the surface of the magnetic core often has certain defects such as bumps, flash, burrs, and dimensional deviations. These defects not only affect the appearance quality of the magnetic core but also adversely affect its electromagnetic properties, such as increasing core loss, reducing permeability, and affecting the stability of inductance. To eliminate these defects and ensure the precision of the magnetic core, grinding has become an indispensable and important process in the magnetic core production process.

[0004] Currently, when grinding the two end faces of a toroidal magnetic core, the core is usually placed directly on a worktable and ground with a grinding wheel. During the sintering process, the surface of the core may have certain bumps, burrs, or other defects. When a core with bumps, burrs, or other defects is placed on a worktable for grinding, the defects will cause the core to be tilted during grinding, resulting in a slanted surface after grinding. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a grinding table for magnetic core production. By setting up a magnetic core grinding platform, the magnetic core can be prevented from being in an inclined state during grinding, thus avoiding the situation where the ground surface of the magnetic core is also inclined, which would affect the accuracy of the magnetic core. The specific structure is as follows:

[0006] A grinding table for producing magnetic cores includes a magnetic core grinding platform; the magnetic core grinding platform includes a base; baffles are fixedly connected to the top of both sides of the base;

[0007] Each of the two baffles has a chain on one side of its opposite surface; each of the two baffles has two sprockets rotatably connected to both sides; the two sprockets located on the right side of the two baffles are connected by a drive shaft and driven by a first motor.

[0008] Multiple corresponding mounting blocks are fixedly connected to one side of the two chains; each mounting block is provided with a clamping assembly; the clamping assembly includes a slide rod; each mounting block is slidably connected with a slide rod, and the slide rod extends between two opposite mounting blocks;

[0009] The sliding rods are all fixedly connected to the opposite side surfaces, and the locking pins are used to insert into the through holes of the magnetic core; the sliding rods are all fixedly connected to the opposite side end faces, and the gears are at a certain distance from the top end face of the baffle.

[0010] The top of the two baffles is fixedly connected to Z-shaped plates on both sides of the baffle, and the Z-shaped plates are composed of inner plates, inclined plates and outer plates; when the chain drives the gear to rotate counterclockwise to the position of the Z-shaped plate, the gear is located on the opposite side of the two inner plates. Then the gear will move along the Z-shaped plate and move away from each other, while pulling the slide rod and the locking shaft away from each other.

[0011] A feeding assembly is provided between the two outer plates on the two Z-shaped plates on the right side of the two baffles, and the feeding assembly is used to feed the magnetic core;

[0012] On the left side of the two Z-shaped plates of the two baffles, a semi-ring plate is fixedly connected to the two outer plates on the side away from the inclined plate, and the semi-ring plate extends to the position below the baffle; a feeding assembly is provided between the two semi-ring plates, and the feeding assembly is used to feed the ground magnetic core.

[0013] A grinding component is provided between the feeding component and the unloading component, and the grinding component is used to grind the magnetic core.

[0014] Preferably, the feeding assembly includes a feeding cylinder, which is a rectangular cylinder; the top of the feeding cylinder has an opening and the bottom is closed; a support rod is fixedly connected to the bottom of the feeding cylinder, and the two sides of the support rod are respectively fixedly connected to a baffle.

[0015] The feed cylinder has notches on both sides of the Z-shaped plate at the bottom, and these notches are connected to the inner cavity of the feed cylinder. The side of the feed cylinder facing the grinding assembly is connected to a cover door via a torsion spring, and the cover door is initially closed. When the clamping assembly moves to the Z-shaped plates on both sides of the feed cylinder, the gears are located on opposite sides of the two inner plates. The gears then move along the Z-shaped plates and move away from each other, pulling the sliding rod and the locking shaft away from each other. The locking shafts that are moving away from each other pass through both sides of the feed cylinder. When the gears disengage from the outer plate, the sliding rod and the locking shaft return to their initial state under the action of the spring. At this time, the locking shaft that has returned to its initial state will be inserted into the through hole of the magnetic core at the bottom of the feed cylinder through the notch.

[0016] The feeding assembly includes a feeding plate, which is fixedly connected to the base via an L-shaped plate. When the clamping assembly moves the magnetic core to the Z-shaped plate position on both sides of the feeding plate, the gear is located on the opposite side of the two inner plates. The gear will then move along the Z-shaped plate and move away from each other, while pulling the slide rod and the locking shaft away from each other. It will then continue to move along the semi-circular plate and drive the locking shaft to pass through both sides of the feeding plate. The feeding plate will not obstruct the movement of the locking shaft and the slide rod.

[0017] Preferably, the grinding assembly includes a support shaft; support shafts are installed on both sides of the base;

[0018] Mounting plates are fixedly connected to both of the support shafts; a rotating rod is fixedly connected to both mounting plates, and the rotating rod is driven by a second motor; two grinding wheels are installed on the rotating rod. When the magnetic core moves to the position of the grinding wheels, the magnetic core will pass between the grinding wheels, and the rotating grinding wheels will grind the two end faces of the magnetic core, and the grinding wheels will not contact the sliding rod.

[0019] A toothed belt is provided between the two Z-shaped plates located on the two baffles, and the toothed belt is rotatably installed inside the baffle and driven by a third motor; the teeth on the toothed belt mesh with the passing gears.

[0020] Preferably, a limiting sleeve is rotatably mounted between the two grinding wheels on the rotating rod.

[0021] Preferably, an extrusion plate is provided above both of the toothed belts, and the extrusion plates are fixedly connected to the baffle by L-shaped plates; the extrusion plates are bent from the side facing the upper cylinder to the opposite side.

[0022] Preferably, the left side of the feeding cylinder is provided with two limiting plates between the two baffles, and two fixing rods are installed at the bottom of the limiting plates, and the fixing rods are respectively fixedly connected to the baffles;

[0023] The distance between the two limiting plates is the same as the height of the magnetic core. The magnetic core will move between the two limiting plates. The top of the limiting plates is located below the through hole of the magnetic core. The two limiting plates bend from the side facing the upper cylinder to the opposite side. The opposite end faces of the two limiting plates are fixedly connected to the support plate, and the top of the support plate is a semi-circular smooth surface.

[0024] Preferably, the outer ring surface of the card shaft is provided with uniformly arranged sliding grooves; each of the sliding grooves is slidably connected to an extrusion block, and the extrusion block is made of elastic rubber material.

[0025] Preferably, each of the card shafts has a sliding cavity on the end face away from the slide bar, and the sliding cavity is connected to multiple sliding grooves;

[0026] Each of the sliding cavities is slidably connected to a tapered rod, and the side of the extrusion block closest to the tapered rod is in contact with the cylindrical rod; a spring is fixedly connected to the tapered rod, and the spring is fixedly connected inside the sliding cavity, and in the initial state, the cylindrical rod extends out of the outer side of the retaining shaft.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. The grinding table for magnetic core production described in this invention controls the chain to drive the clamping assembly to rotate cyclically, allowing the clamping assembly to clamp the magnetic core from the through hole position. Then, two grinding wheels directly grind both sides of the magnetic core. In this process, it is not necessary to place the magnetic core on the worktable for grinding. At the same time, it can avoid the situation where the magnetic core is placed on the worktable, which would cause the magnetic core to be in a tilted state during grinding, resulting in a sloping surface after grinding, which would affect the accuracy of the magnetic core. In addition, no manual operation is required, thus saving labor costs.

[0029] 2. The grinding table for producing magnetic cores according to the present invention allows the magnetic core to contact the limiting cylinder when it moves to below the grinding wheel. Simultaneously, since the bottom of the magnetic core contacts the support plate, the limiting cylinder and support plate can limit the magnetic core's position. Combined with the limiting plate's position, the magnetic core is positioned precisely between the two grinding wheels and remains horizontal. Therefore, when grinding the magnetic core, only the two sides need to be ground, preventing misalignment or tilting. Attached Figure Description

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0043] like Figures 1 to 10 As shown, the grinding table for magnetic core production according to the present invention is specifically as follows:

[0044] The system includes a magnetic core grinding platform; the magnetic core grinding platform includes a base 1; baffles 11 are fixedly connected to the top of both sides of the base 1;

[0045] Each of the two baffles 11 has a chain 12 on one side of its opposite surface; each of the two baffles 11 has two sprockets 13 rotatably connected to both sides; the two sprockets 13 located on the right side of the two baffles 11 are connected by a drive shaft 14 and driven by a first motor 15.

[0046] Multiple corresponding mounting blocks 16 are fixedly connected to one side surface of the two chains 12; each mounting block 16 is provided with a clamping assembly; the clamping assembly includes a slide rod 2; each mounting block 16 is slidably connected with a slide rod 2, and the slide rod 2 extends between the two opposite mounting blocks 16;

[0047] The sliding rod 2 is fixedly connected to the opposite side surface of each of the sliding rods 2, and the locking shaft 22 is used to insert into the through hole of the magnetic core 17; the sliding rod 2 is fixedly connected to the opposite side end face of each of the sliding rods 2, and there is a certain distance between the gear 21 and the top end face of the baffle 11.

[0048] The tops of the two baffles 11 are fixedly connected to Z-shaped plates 3 on both sides of the baffles 11, and the Z-shaped plates 3 are composed of inner plates 31, inclined plates 32 and outer plates 33. When the chain 12 drives the gear 21 to rotate counterclockwise to the position of the Z-shaped plate 3, the gear 21 is located on the opposite side of the two inner plates 31. Then the gear 21 will move along the Z-shaped plate 3 and move away from each other, while pulling the slide bar 2 and the locking shaft 22 away from each other.

[0049] A feeding assembly is provided between the two outer plates 33 on the two Z-shaped plates 3 on the right side of the two baffles 11, and the feeding assembly is used to feed the magnetic core 17.

[0050] On the left side of the two Z-shaped plates 3, the two outer plates 33 are fixedly connected to the side end face away from the inclined plate 32, and the semi-ring plate 34 extends to the position below the baffle 11; a feeding assembly is provided between the two semi-ring plates 34, and the feeding assembly is used to feed the ground magnetic core 17.

[0051] A grinding component is provided between the feeding component and the unloading component, and the grinding component is used to grind the magnetic core 17.

[0052] In this embodiment, the feeding assembly includes a feeding cylinder 4, which is a rectangular cylinder; the top of the feeding cylinder 4 is open and the bottom is closed; the bottom of the feeding cylinder 4 is fixedly connected to a support rod 41, and the two sides of the support rod 41 are respectively fixedly connected to the baffle 11.

[0053] The two end faces of the feeding cylinder 4 facing the Z-shaped plate 3 are provided with notches 42 at the bottom of the feeding cylinder 4, and the notches 42 are connected to the inner cavity of the feeding cylinder 4. The side of the feeding cylinder 4 facing the grinding assembly is connected to the cover door 43 by a torsion spring, and the cover door 43 is initially closed. When the clamping assembly moves to the Z-shaped plates 3 on both sides of the feeding cylinder 4, the gear 21 is located on the opposite side of the two inner plates 31. Then the gear 21 will move along the Z-shaped plate 3 and move away from each other. At the same time, it will pull the sliding rod 2 and the locking shaft 22 away from each other. The locking shaft 22, which moves away from each other, will pass through both sides of the feeding cylinder 4. When the gear 21 is disengaged from the outer plate 33, the sliding rod 2 and the locking shaft 22 will return to their initial state under the action of the spring. At this time, the locking shaft 22, which has returned to its initial state, will be inserted into the through hole of the magnetic core 17 at the bottom of the feeding cylinder 4 through the notch 42.

[0054] The unloading assembly includes an unloading plate 44, which is fixedly connected to the base 1 via an L-shaped plate. When the clamping assembly moves the magnetic core 17 to the Z-shaped plate 3 on both sides of the unloading plate 44, the gear 21 is located on the opposite side of the two inner plates 31. Then the gear 21 will move along the Z-shaped plate 3 and move away from each other, while pulling the slide bar 2 and the locking shaft 22 away from each other. Then it will continue to move along the semi-circular plate 34 and drive the locking shaft 22 to pass through both sides of the unloading plate 44. The unloading plate 44 will not obstruct the movement of the locking shaft 22 and the slide bar 2.

[0055] In this embodiment, the grinding assembly includes a support shaft 45; support shafts 45 are installed on both sides of the base 1.

[0056] Mounting plates 46 are fixedly connected to both support shafts 45; a rotating rod is fixedly connected to both mounting plates 46, and the rotating rod is driven by a second motor 47; two grinding wheels 48 are installed on the rotating rod. When the magnetic core 17 moves to the position of the grinding wheels 48, the magnetic core 17 will pass between the grinding wheels 48. The rotating grinding wheels 48 will grind the two end faces of the magnetic core 17, and the grinding wheels 48 will not contact the slide rod 2.

[0057] A toothed belt 49 is provided between the two Z-shaped plates 3 located on the two baffles 11, and the toothed belt 49 is rotatably installed inside the baffle 11 and driven by a third motor 491; the teeth on the toothed belt 49 mesh with the passing gear 21.

[0058] Specifically, during the grinding of the magnetic core 17, the magnetic core 17 is first transferred into the loading cylinder 4. The magnetic cores 17 entering the loading cylinder 4 are stacked sequentially. Then, the first motor 15 is controlled to rotate. The rotating first motor 15 drives the drive shaft 14 and the two sprockets 13 on the drive shaft 14 to rotate. The two rotating sprockets 13 drive the two chains 12 to rotate counterclockwise. When the chains 12 move the clamping assembly to the Z-shaped plate 3 position in the loading cylinder 4, the gear 21 on the clamping assembly moves to the opposite end faces of the two inner plates 31. The gear 21 then continues to move along the inclined plate 32 and the outer plate 33. During the movement of the gear 21, the sliding rod 2 and the retaining shaft 22 move away from each other, causing the retaining shaft 22 to pass through both sides of the loading cylinder 4. After the gear 21 disengages from the outer plate 33, the spring... The sliding rod 2 and the locking shaft 22 will return to their initial state. At this time, the locking shaft 22, which has returned to its initial state, will be inserted into the through hole of the magnetic core 17 at the bottom of the loading cylinder 4 through the notch 42 on the loading cylinder 4. Then the chain 12 will continue to move, thereby driving the clamping assembly to move. The sliding rod 2 and the locking shaft 22 on the clamping assembly will drive the magnetic core 17 to move. During the movement of the magnetic core 17, it will squeeze the cover 43 on the loading cylinder 4. The cover 43 will rotate against the elastic force of the torsion spring. Then the magnetic core 17 will be moved out of the loading cylinder 4, and the cover 43 will return to its initial state. Then the magnetic core 17 will move towards the grinding assembly position. At the same time, the rotating chain 12 will drive the clamping assembly through the loading cylinder 4 in turn. When each clamping assembly passes through the loading cylinder 4, under the action of the Z-shaped plate 3, a magnetic core 17 will be brought out of the loading cylinder 4.

[0059] More specifically, as the clamping assembly moves the magnetic core 17, the slide bar 2 clamping the magnetic core 17 gradually moves between the grinding wheel 48 and the toothed belt 49. As the magnetic core 17 gradually approaches the grinding wheel 48, the second motor 47 and the third motor 491 are controlled to rotate. When the second motor 47 rotates, it drives the two grinding wheels 48 to rotate. When the third motor 491 rotates, it drives the toothed belt 49 to rotate. The rotating toothed belt 49 drives the gear 21 to rotate. The rotating gear 21 drives the slide bar 2, the clamping shaft 22, and the magnetic core 17 to rotate. The rotation direction of the magnetic core 17 is opposite to the rotation direction of the grinding wheel 48. Therefore, when the rotating magnetic core 17 passes the grinding wheel 48, the rotating grinding wheel 48 grinds the two end faces of the magnetic core 17.

[0060] Furthermore, after the magnetic core 17 is polished, the clamping assembly will move the magnetic core 17 to the Z-shaped plate 3 on one side of the unloading assembly. When the clamping assembly moves the magnetic core 17 to the Z-shaped plates 3 on both sides of the unloading plate 44, the gear 21 is located on the opposite side of the two inner plates 31. Then the gear 21 will move along the Z-shaped plate 3 and move away from each other, while pulling the slide rod 2 and the retaining shaft 22 away from each other. During the process of the retaining shaft 22 moving away from each other, the retaining shaft 22 is gradually pulled out from the magnetic core 17. When the gear 21 moves to the outer plate 33, the retaining shaft 22 is then pulled out. Completely pulled out of the through hole of the magnetic core 17, the magnetic core 17 will fall onto the feed plate 44 and roll down along the feed plate 44. At the same time, after the gear 21 disengages from the outer plate 33, the gear 21 will continue to move along the semi-ring plate 34 and drive the locking shaft 22 to pass through both sides of the feed plate 44. The feed plate 44 will not obstruct the movement of the locking shaft 22 and the slide rod 2. After the gear 21 disengages from the semi-ring plate 34, the slide rod 2 and the locking shaft 22 return to their initial state. At this time, the locking shaft 22 and the slide rod 2, which have returned to their initial state, are located below the feed plate 44. This cycle continues.

[0061] Furthermore, by controlling the chain 12 to drive the clamping assembly to rotate cyclically, the clamping assembly can clamp the magnetic core 17 from the through hole position of the magnetic core 17. Then, the two grinding wheels 48 directly grind both sides of the magnetic core 17. In this process, it is not necessary to place the magnetic core 17 on the worktable for grinding. At the same time, it can avoid the situation where the magnetic core 17 is placed on the worktable, which would cause the magnetic core 17 to be in a tilted state during grinding, resulting in the surface of the magnetic core 17 after grinding being also a slope, thus affecting the accuracy of the magnetic core 17. At the same time, no manual operation is required, thus saving labor costs. Example

[0062] A limiting sleeve 481 is rotatably mounted on the rotating rod between the two grinding wheels 48;

[0063] In this embodiment, an extrusion plate 35 is provided above each of the two toothed belts 49, and the extrusion plate 35 is fixedly connected to the baffle 11 by an L-shaped plate; the extrusion plate 35 is bent from the side facing the upper feed cylinder 4 to the opposite side.

[0064] In this embodiment, two limiting plates 36 are provided on the left side of the feeding cylinder 4 between the two baffles 11, and two fixing rods 37 are installed at the bottom of the limiting plates 36, and the fixing rods 37 are respectively fixedly connected to the baffles 11.

[0065] The distance between the two limiting plates 36 is the same as the height of the magnetic core 17. The magnetic core 17 will move between the two limiting plates 36. The top of the limiting plate 36 is located below the through hole of the magnetic core 17. The two limiting plates 36 are bent to opposite sides of the upper feed cylinder 4. The opposite end faces of the two limiting plates 36 are fixedly connected to the support plate 38, and the top of the support plate 38 is a semi-circular smooth surface.

[0066] Specifically, after the clamping shaft 22 brings the magnetic core 17 out of the feeding cylinder 4, the chain 12 will continue to drive the clamping assembly and the magnetic core 17 to move. Since the toothed belt 49 is provided with an extrusion plate 35, the moving gear 21 will gradually contact the curved side of the extrusion plate 35 and then continue to move along the extrusion plate 35. If the clamping shaft 22 is not fully inserted into the through hole of the magnetic core 17, under the limiting guidance of the extrusion plate 35, the gear 21 will be pushed to move. The moving gear 21 will drive the slide bar 2 and the clamping shaft 22 to move, so that the clamping shaft 22 can be fully inserted into the magnetic core 17 and the opposite clamping shafts 22 will fit together, thereby avoiding the clamping shaft 22 not being fully inserted into the through hole of the magnetic core 17.

[0067] More specifically, after the clamping shaft 22 brings the magnetic core 17 out of the loading cylinder 4, the chain 12 will continue to drive the clamping assembly and the magnetic core 17 to move. Since the distance between the two limiting plates 36 is the same as the height of the magnetic core 17, the magnetic core 17 will first move along the curved side of the limiting plate 36. Then, under the limiting and guiding of the limiting plate 36, the magnetic core 17 will move along the limiting plate 36. During this process, the position of the magnetic core 17 can be limited so that the magnetic core 17 is located between the two grinding wheels 48.

[0068] Furthermore, when the magnetic core 17 moves below the grinding wheel 48, the magnetic core 17 will contact the limiting cylinder 481. At the same time, since the bottom of the magnetic core 17 is in contact with the support plate 38, the limiting cylinder 481 and the support plate 38 can limit the magnetic core 17. With the limiting plate 36 limiting the magnetic core 17, the magnetic core 17 can be positioned exactly between the two grinding wheels 48 and kept in a horizontal state. Therefore, when grinding the magnetic core 17, only the two sides of the magnetic core 17 can be ground, which can prevent the magnetic core 17 from being misaligned or tilted.

[0069] At the same time, the distance between the two grinding wheels 48 and the height of the grinding wheels 48 themselves can be adjusted according to the specifications of the magnetic core 17, and the distance between the two limiting plates 36 can also be adjusted so as to grind magnetic cores 17 of different specifications. Example

[0070] The outer ring surface of the clasp 22 is provided with uniformly arranged sliding grooves 23; each of the sliding grooves 23 is slidably connected with an extrusion block 24, and the extrusion block 24 is made of elastic rubber material;

[0071] In this embodiment, each of the card shafts 22 has a sliding cavity 25 on the side face away from the slide bar 2, and the sliding cavity 25 is connected to a plurality of sliding grooves 23;

[0072] Each of the sliding cavities 25 is slidably connected with a tapered rod 26, and the side of the extrusion block 24 near the tapered rod 26 is in contact with the cylindrical rod; a spring is fixedly connected to the tapered rod 26, and the spring is fixedly connected inside the sliding cavity 25. In the initial state, the cylindrical rod extends out of the outside of the retaining shaft 22.

[0073] Specifically, since the pressing block 24 slides in the groove 23 on the clamping shaft 22, when the clamping shaft 22 is inserted into the through hole of the magnetic core 17, under the limitation of the pressing plate 35, the two clamping shafts 22 can be made to stick together. The clamping shafts 22 that stick together will press the tapered rod 26. When the tapered rod 26 is pressed, it will move into the sliding cavity 25 and press multiple pressing blocks 24. When the pressing blocks 24 are pressed, they will press the through hole of the magnetic core 17, thereby fixing the magnetic core 17. Since the pressing block 24 is made of elastic rubber material, the pressing will deform during the pressing of the magnetic core 17, thereby avoiding the magnetic core 17 from being crushed.

[0074] More specifically, due to the presence of the limiting plate 36, when the retaining shaft 22 is pulled out from the through hole of the magnetic core 17, the limiting plate 36 can limit the magnetic core 17, preventing the magnetic core 17 from moving with one of the retaining shafts 22, thus preventing the magnetic core 17 from detaching from the retaining shaft 22 and making it impossible to complete the unloading process.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
