Description

Technical Field

[0001] The invention belongs to the technical field of magnetic core production, in particular to a grinding table for magnetic core production. Background Art

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

[0003] Magnetic cores are usually made of magnetic materials such as ferrite, iron powder core, amorphous alloy, etc. During the production process, after the molding process, the surface of the magnetic core often has certain bumps, flash, burrs, and dimensional deviations. These defects not only affect the appearance quality of the magnetic core, but also have adverse effects on its electromagnetic properties, such as increasing core loss, reducing magnetic permeability, and affecting the stability of inductance. In order to eliminate these defects and ensure the accuracy of the magnetic core, grinding has become an indispensable and important process in the production process of magnetic cores.

[0004] At present, when grinding the end faces of both sides of the annular magnetic core, the magnetic core is generally placed directly on a workbench and ground with a grinding wheel. During the sintering process of the magnetic core, certain bumps, flash or burrs will appear on the surface of the magnetic core. When the magnetic core with bumps, flash or burrs is placed on the workbench for grinding, the presence of defects will cause the magnetic core to be in a tilted state during grinding, resulting in the ground surface of the magnetic core also being an inclined surface.

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, and then the gear 21 will move along the Z-shaped plate 3 and move away from each other, and at the same time pull the slide bar 2 and the card shaft 22 away from each other;

In this embodiment, the loading assembly includes a loading barrel 4, and the loading barrel 4 is a rectangular barrel; the loading barrel 4 is provided with an opening at the top and is closed at the bottom; the bottom of the loading barrel 4 is fixedly connected to a support rod 41, and both sides of the support rod 41 are respectively fixedly connected to the baffle 11; The two side end surfaces of the upper barrel 4 facing the Z-shaped plate 3 are provided with notches 42 at the bottom of the upper barrel 4, and the notches 42 are connected to the inner cavity of the upper barrel 4; the upper barrel 4 is connected to a cover door 43 by a torsion spring rotation toward the grinding assembly, and the cover door 43 is closed in the initial state; when the clamping assembly moves to the Z-shaped plates 3 on both sides of the upper barrel 4, the gear 21 is located on the opposite side of the two inner plates 31, and then the gear 21 will move along the Z-shaped plates 3 and move away from each other, and at the same time, it will pull the slide bar 2 and the card shaft 22 away from each other, and the card shaft 22 moving away from each other will pass through the two sides of the upper barrel 4, and when the gear 21 is detached from the outer plate 33, the slide bar 2 and the card shaft 22 will return to their initial state under the action of the spring, and the card shaft 22 restored to its initial state will be inserted into the through hole of the magnetic core 17 at the bottom of the upper barrel 4 through the notch 42; The blanking assembly includes a blanking plate 44, and the blanking plate 44 is fixedly connected to the base 1 through an L-shaped plate; when the clamping assembly drives the magnetic core 17 to move to the position of the Z-shaped plate 3 on both sides of the blanking plate 44, the gear 21 is located on the opposite side of the two inner plates 31, and then the gear 21 moves along the Z-shaped plate 3 and moves away from each other, and at the same time pulls the slide bar 2 and the clamping shaft 22 away from each other, and then continues to move along the semi-ring plate 34, and drives the clamping shaft 22 to pass through both sides of the blanking plate 44, and the blanking plate 44 will not hinder the movement of the clamping shaft 22 and the slide bar 2; In this embodiment, the grinding assembly includes a support shaft 45; support shafts 45 are installed on both sides of the base 1; The two support shafts 45 are both fixedly connected to the mounting plates 46; the two mounting plates 46 are commonly fixedly connected to the rotating rod, and the rotating rod is driven by the 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, and the rotating grinding wheels 48 will grind the end surfaces of both sides of the magnetic core 17, and the grinding wheels 48 do not contact the sliding rod 2; A toothed belt 49 is provided between the two Z-shaped plates 3 on the two baffles 11, and the toothed belt 49 is rotatably mounted in the baffle 11 and driven by a third motor 491; the teeth on the toothed belt 49 mesh with the passing gear 21; Specifically, when grinding the magnetic core 17, the magnetic core 17 is first transferred to the upper barrel 4. The magnetic core 17 entering the upper barrel 4 will be stacked in sequence in the upper barrel 4, and then the first motor 15 is controlled to rotate. The rotating first motor 15 will drive the driving shaft 14 and the two sprockets 13 on the driving shaft 14 to rotate, and the two rotating sprockets 13 will drive the two chains 12 to rotate counterclockwise. When the chain 12 drives the clamping assembly to move to the Z-shaped plate 3 position of the upper barrel 4, the gear 21 on the clamping assembly will move to the opposite side end surface of the two inner plates 31, and then the gear 21 will continue to move along the inclined plate 32 and the outer plate 33. In the process of the movement of the gear 21, the slide bar 2 and the clamping shaft 22 will be driven away from each other, so that the clamping shaft 22 will pass through both sides of the upper barrel 4. When the gear 21 is detached from the outer plate 33, the spring The sliding rod 2 and the clamping shaft 22 will restore their initial state under the action of , and the clamping shaft 22 restored to the initial state will be inserted into the through hole of the magnetic core 17 at the bottom of the upper barrel 4 through the notch 42 on the upper barrel 4, and then the chain 12 will continue to move, thereby driving the clamping assembly to move, and the sliding rod 2 and the clamping shaft 22 on the clamping assembly will drive the magnetic core 17 to move. In the process of the movement of the magnetic core 17, the cover door 43 on the upper barrel 4 will be squeezed, and the cover door 43 will overcome the elastic force of the torsion spring and rotate, and then the magnetic core 17 will move out of the upper barrel 4, and the cover door 43 will restore its initial state, and then the magnetic core 17 will move toward the grinding assembly position, and at the same time, the rotating chain 12 will drive the clamping assembly to pass through the upper barrel 4 in turn, and when each clamping assembly passes through the upper barrel 4, under the action of the Z-shaped plate 3, a magnetic core 17 will be taken out of the upper barrel 4; More specifically, when the clamping assembly drives the magnetic core 17 to move, the slide bar 2 clamping the magnetic core 17 will gradually move between the grinding wheel 48 and the toothed belt 49. When 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 will drive the two grinding wheels 48 to rotate. When the third motor 491 rotates, it will drive the toothed belt 49 to rotate. The rotating toothed belt 49 will drive the gear 21 to rotate. The rotating gear 21 will drive 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 that of the grinding wheel 48. Therefore, when the rotating magnetic core 17 passes through the grinding wheel 48, the rotating grinding wheel 48 will grind the end faces of both sides of the magnetic core 17. Furthermore, when the grinding of the magnetic core 17 is completed, the clamping assembly will drive the magnetic core 17 to move to the position of the Z-shaped plate 3 on one side of the blanking assembly. When the clamping assembly drives the magnetic core 17 to move to the position of the Z-shaped plate 3 on both sides of the blanking 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, and at the same time, it will pull the slide bar 2 and the clamping shaft 22 away from each other. In the process of the clamping shaft 22 moving away from each other, the clamping shaft 22 is gradually pulled out of the magnetic core 17. When the gear 21 moves to the position of the outer plate 33, the clamping shaft 22 The magnetic core 17 is completely pulled out from the through hole of the magnetic core 17. At this time, the magnetic core 17 will fall on the blanking plate 44 and roll down along the blanking plate 44. At the same time, when the gear 21 is detached from the outer plate 33, the gear 21 will continue to move along the semi-ring plate 34 and drive the clamping shaft 22 to pass through both sides of the blanking plate 44. The blanking plate 44 will not hinder the movement of the clamping shaft 22 and the slide bar 2. When the gear 21 is detached from the semi-ring plate 34, the slide bar 2 and the clamping shaft 22 return to their initial state. At this time, the clamping shaft 22 and the slide bar 2 that have returned to their initial state are located below the blanking plate 44, and the cycle continues. Furthermore, by controlling the chain 12 to drive the clamping assembly to rotate in a circular motion, the clamping assembly can clamp the magnetic core 17 from the through-hole position of the magnetic core 17, and then the two sides of the magnetic core 17 are directly ground by two grinding wheels 48. In this process, there is no need to place the magnetic core 17 on the workbench for grinding. At the same time, it can be avoided that when the magnetic core 17 is placed on the workbench, the magnetic core 17 is in a tilted state during grinding, which causes the ground surface of the magnetic core 17 to also be an inclined surface, thereby affecting the accuracy of the magnetic core 17. At the same time, no manual operation is required, thereby saving labor costs. Example

[0020] A limiting cylinder 481 is rotatably mounted on the rotating rod between the two grinding wheels 48; In this embodiment, an extrusion plate 35 is provided above the two toothed belts 49, and the extrusion plates 35 are fixedly connected to the baffle 11 through an L-shaped plate; the extrusion plate 35 is bent toward the opposite side from the side facing the upper barrel 4; In this embodiment, two limit plates 36 are provided on the left side of the upper barrel 4 between the two baffles 11, and two fixing rods 37 are installed at the bottom of the limit plates 36, and the fixing rods 37 are fixedly connected to the baffles 11 respectively; The distance between the two limit plates 36 is the same as the height of the magnetic core 17. The magnetic core 17 will move between the two limit plates 36. The top of the limit plate 36 is located below the through hole of the magnetic core 17. The two limit plates 36 are bent toward the opposite side from the side facing the loading barrel 4. The end surfaces of the opposite sides of the two limit plates 36 are fixedly connected to the support plate 38, and the top of the support plate 38 is a semicircular smooth surface. Specifically, when the clamping shaft 22 brings the magnetic core 17 out of the loading barrel 4, the chain 12 will continue to drive the clamping assembly and the magnetic core 17 to move. Since an extrusion plate 35 is provided above the toothed belt 49, 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, the gear 21 will be pushed to move under the limit guidance of the extrusion plate 35. 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 completely inserted into the magnetic core 17, and the relative clamping shafts 22 can fit each other, thereby preventing the clamping shaft 22 from being fully inserted into the through hole of the magnetic core 17. More specifically, when the clamping shaft 22 brings the magnetic core 17 out of the loading barrel 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, and then under the limitation and guidance of the limiting plate 36, the magnetic core 17 will move along the limiting plate 36. In 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. Furthermore, when the magnetic core 17 moves to 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 contacts the support plate 38, the limiting cylinder 481 and the support plate 38 can limit the magnetic core 17. At the same time, the limiting plate 36 can limit the magnetic core 17, so that the magnetic core 17 can be located exactly between the two grinding wheels 48 and the magnetic core 17 is 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 avoid the magnetic core 17 from being misplaced or tilted. At the same time, the distance between the two grinding wheels 48 and the height of the grinding wheels 48 can be adjusted according to the specifications of the magnetic core 17, and the distance between the two limiting plates 36 can be adjusted at the same time, so as to grind the magnetic cores 17 of different specifications. Example

[0021] The outer ring surface of the clamping shaft 22 is provided with evenly 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; In this embodiment, a sliding cavity 25 is formed on the end surface of each of the clamping shafts 22 away from the slide rod 2, and the sliding cavity 25 is connected to a plurality of sliding grooves 23; The sliding cavity 25 is slidably connected with a conical rod 26, and the side of the extrusion block 24 close to the conical rod 26 is in contact with the columnar rod; the conical rod 26 is fixedly connected with a spring, and the spring is fixedly connected in the sliding cavity 25, and in the initial state, the columnar rod part extends out of the outside of the clamping shaft 22; Specifically, since there is an extrusion block 24 sliding in the slide groove 23 on the card shaft 22, when the card shaft 22 is inserted into the through hole of the magnetic core 17, under the limit of the extrusion plate 35, the two card shafts 22 can be fitted together, and the card shafts 22 fitted together will squeeze the tapered rod 26. When the tapered rod 26 is squeezed, it will move into the slide cavity 25 and squeeze a plurality of extrusion blocks 24. When the extrusion blocks 24 are squeezed, they will squeeze the through hole of the magnetic core 17, thereby fixing the magnetic core 17. Since the extrusion blocks 24 are made of elastic rubber material, they will be deformed during the process of squeezing the magnetic core 17, thereby avoiding squeezing the magnetic core 17. More specifically, due to the presence of the limit plate 36, when the clamping shaft 22 is pulled out from the through hole of the magnetic core 17, the limit plate 36 can limit the magnetic core 17 to prevent the magnetic core 17 from moving with one of the clamping shafts 22, thereby causing the magnetic core 17 to be unable to detach from the clamping shaft 22 and the unloading process to be unable to be realized.
