Description

Technical Field

[0001] This invention relates to the field of magnetic core manufacturing technology, specifically to a magnetic core manufacturing equipment and method. Background Technology

[0002] The magnetic core is the core magnetic component of a transformer that realizes electromagnetic energy conversion and isolation. The magnetic core is a closed or nearly closed magnetic circuit made of soft magnetic material with high permeability and low loss characteristics. In a transformer, the core function of the magnetic core is to establish and constrain the alternating magnetic flux generated by the primary winding current, forming a magnetic path with low magnetic resistance and high coupling efficiency, so as to realize the efficient transmission and voltage transformation of electrical energy through the form of magnetic field. However, there are still some shortcomings in the current technology for producing magnetic cores.

[0003] The invention patent with publication number CN118737676A discloses a cutting device for producing high-frequency transformer cores, including a base plate assembly. A pushing assembly is slidably mounted on the base plate assembly. A clamping assembly, a cutting mechanism, and a driving assembly are sequentially arranged on the front side of the pushing assembly. The cutting mechanism is also fixedly installed on the top of the base plate assembly in front of the clamping assembly. The pushing assembly includes a right push plate and a left push plate. Sliding handles are fixedly installed on both sides of the right push plate. This cutting device for producing high-frequency transformer cores, through the arrangement of the base plate assembly and the driving assembly on it, can adjust the position of the driving disc and the motor disc on it through a second hydraulic cylinder, thereby fitting the front end of the core and squeezing and limiting it by an airbag seat. At the same time, the motor disc drives the entire core to rotate and gradually contact the cutting mechanism, realizing rotary cutting.

[0004] Although the above-mentioned device can achieve rotary cutting of the magnetic core, it cannot lift the magnetic core first and then clamp it during use, which makes it inconvenient to extend the longitudinal working space during subsequent cutting. It cannot achieve the production length adjustment function of C-type magnetic core by using a single cutting device in conjunction with the switching structure, and it cannot use the overload protection structure of the cutting component to achieve the cutting surface grinding function. Summary of the Invention

[0010] As a further embodiment of the present invention: the first connecting shell, the connecting column and the connecting frame are fixedly connected as an integral structure, the connecting columns are symmetrically distributed on both sides of the first connecting shell, and there are gaps between the lower half of the connecting column and the guide frame and the first connecting shell.

[0011] As a further embodiment of the present invention: the mounting shaft is rotatably connected to the second gear, and the second gear and the first gear are rotatably connected to the first connecting shell. A second groove is provided in the mounting shaft, and a second spring is installed in the second groove. A support block is fixedly provided on the second spring. A docking groove for docking with the support block is provided on the second gear. The side of the support block away from the mounting shaft and the central axis is an arc surface.

[0012] As a further embodiment of the present invention: the switching assembly includes a first synchronous wheel rotatably mounted on a mounting shaft, a first keyway being provided in the first synchronous wheel, a key block being provided on the side of the first synchronous wheel, a first key rod being mounted on the key block, a second keyway and a guide groove being provided on the mounting shaft, a first synchronous belt being provided on the outside of the first synchronous wheel, a second synchronous wheel being mounted on the first synchronous belt, a third screw being connected to the second synchronous wheel, and the third screw being threadedly connected to the connecting block.

[0013] As a further embodiment of the present invention: a side plate and a guide rail are installed on the connecting column, a cross bar is welded on the side plate, a slide rod is slidably installed on the outside of the cross bar, a handle is installed on the slide rod, and the connecting block is slidably installed on the outside of the guide rail.

[0014] As a further embodiment of the present invention: the guide frame is provided with a U-shaped groove for guiding the second slider, and a stop block is fixedly connected to the guide frame.

[0015] A method for manufacturing a magnetic core includes the following steps: S1: Place the transformer core on the base, drive the third synchronous wheel to rotate through the first motor, and cooperate with the fixing component to automatically clamp the transformer core after it is lifted. When cutting, first extend the electric push rod to drive the first connecting shell, connecting column and guide frame to move downward. Drive the circular saw to rotate through the third motor. The circular saw completes the first cut of the transformer core. Since the transformer core is flat O-shaped, after the first cut is completed, shorten the electric push rod, adjust the switching component so that the drive component can not only act on the circular saw, adjust the initial position of the second connecting shell, adjust the cutting surface of the circular saw to the symmetrical position of the first cut, reset the switching component, and perform the second cut to cut the O-shaped transformer core into two C-shaped cores of specific length. S2: When the device is cutting, it can cut along a specific trajectory, thereby increasing the cutting range. The first gear is driven to rotate by the second motor, and the first gear drives the second gear to rotate. The friction between the second gear and the mounting shaft causes the mounting shaft and the connecting frame to rotate. When the connecting frame rotates, it will drive the first slider and the second slider to move along a specific trajectory on the guide frame. S3: After the device completes the secondary cutting, the initial height of the circular saw is adjusted by extending or shortening the electric push rod, so that the grinding ring fits against the cutting surface, and the switching component is connected to the mounting shaft, so that the rotation of the mounting shaft acts on the switching component. S4: The guide component allows the circular saw to move left and right along a specific trajectory, and the switching component allows the circular saw to move back and forth. When the grinding ring abuts against the cutting surface and rotates, it can grind the cutting surface. When the circular saw blade becomes dull, the rotational resistance of the mounting shaft increases, and the mounting shaft stops rotating. When the grinding ring abuts against the cutting surface and cannot move further towards the cutting surface, the rotational resistance of the mounting shaft increases, the second gear slides on the mounting shaft, and the circular saw stops moving but still continues to rotate, allowing for targeted grinding of local areas of the cutting surface.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The device is equipped with a support plate, a fixing component, and a third synchronous wheel, realizing the automatic lifting and clamping of the transformer core in an integrated manner. The first motor drives the first and second bidirectional screws to rotate synchronously through the third synchronous wheel and the second synchronous belt, which drives the two support plates on both sides to move towards each other. When the first oblique surface of the support plate contacts the side of the core, it generates an upward component force, lifting it away from the base. When the core is fully clamped, the transmission resistance increases, and the clamping block compresses the first spring, causing the third synchronous wheel to slide on the first connecting shaft, stopping further clamping. This solves the problem of traditional equipment failing to lift the core before clamping, resulting in the cutting tool touching the worktable and insufficient longitudinal working space.

[0017] 2. The device is equipped with a drive assembly, a guide assembly, and a switching assembly, enabling the use of a single circular saw to complete two symmetrical cuts and flexibly adjust the final C-shaped magnetic core length. The connecting frame is rotated via the mounting shaft, and the second slider is guided by the U-shaped groove on the guide frame. After the first cut, the switching assembly is operated to push the handle, connecting the key block with the first and second keyways, changing the power transmission path of the drive assembly, thereby adjusting the initial position of the second connecting shell and the circular saw on the guide rail. During this process, the circular saw can move to a position symmetrical to the first cut surface for the second cut. Compared to existing equipment that requires multiple stations or tools to produce C-shaped magnetic cores, this device achieves segmented cutting with only a single cutting device, improving production flexibility and equipment integration.

[0018] 3. The device is equipped with a second gear, a mounting shaft, and a switching assembly, which realizes overload protection and cutting surface grinding functions when the circular saw blade becomes dull. When the circular saw blade becomes dull, causing its movement resistance to increase, the rotational resistance of the mounting shaft exceeds the preset force of the second spring, the support block retracts, the second gear slides on the mounting shaft, the circular saw stops feeding but continues to rotate, realizing overload protection. When grinding is required, the switching assembly switches the power to drive the circular saw to move back and forth, and drives the third screw to rotate through the first synchronous belt, so that the grinding ring abuts against the cutting surface. At this time, the feed resistance will also trigger the second gear to slide on the mounting shaft, thereby realizing the grinding function for the cutting surface. This solves the problem that traditional magnetic core production equipment cannot use the overload protection structure of the cutting component to realize the cutting surface grinding function, and enhances the safety of the device during use.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0023] Example 1: like Figures 1-14As shown, this embodiment proposes a magnetic core production equipment, including a base 1 and an electric push rod 2. A first motor 3 is mounted on the base 1, and a third synchronous wheel 26 is connected to the output shaft of the first motor 3. A first connecting shaft 4 is rotatably connected inside the third synchronous wheel 26. A fixing assembly 5 is mounted on the first connecting shaft 4, and a transformer magnetic core 7 is disposed on the fixing assembly 5. A first connecting shell 9 is mounted on the bottom of the electric push rod 2. A drive assembly 10 and a guide assembly 17 are mounted on the first connecting shell 9. A switching assembly 11 is mounted on the drive assembly 10. The drive assembly 10 includes a second motor 1001 mounted on the first connecting shell 9. A first gear 1002 is fixedly connected to the output shaft of the second motor 1001. A second gear 1003 is meshed with the first gear 1002. An installation shaft 1004 is mounted on the second gear 1003. The guide assembly 17 includes a connecting frame 1701 fixedly connected to the installation shaft 1004. A first slider 1702 is slidably mounted on the connecting frame 1701. A second slider 1703 is fixedly connected to 1702. A guide frame 1705 is provided on the outer side of the second slider 1703. A connecting post 1704 is installed on the guide frame 1705 and connected to the first connecting shell 9. A connecting block 12 is installed on the switching assembly 11. A second connecting shell 13 is connected below the connecting block 12. A third motor 14 is installed on the second connecting shell 13. A circular saw 15 is connected to the output shaft of the third motor 14. A grinding ring 16 is installed on the circular saw 15. The transformer core 7 is placed on the base 1. The first motor 3 drives the third synchronous wheel 26 to rotate. Together with the fixing assembly 5, the transformer core 7 can be automatically clamped after being lifted. During cutting, the electric push rod 2 extends, causing the first connecting shell 9, connecting column 1704, and guide frame 1705 to move downwards. The third motor 14 drives the circular saw 15 to rotate, completing the first cut of the transformer core 7. Because the transformer core 7 is a flat O-shape, after one cut, as... Figure 9 and Figure 10 As shown, by shortening the electric push rod 2 and adjusting the switching component 11, the drive component 10 can not only act on the circular saw 15, but also adjust the initial position of the second connecting shell 13, adjust the cutting surface of the circular saw 15 to the symmetrical position of the first cut, reset the switching component 11, and perform the second cut, thereby cutting the O-type transformer core 7 into two C-type cores of specific lengths.

[0024] The device can cut along a specific trajectory during cutting, thereby increasing the cutting range, such as... Figure 1 and Figures 5-7As shown, the second motor 1001 drives the first gear 1002 to rotate, and the first gear 1002 drives the second gear 1003 to rotate. The friction between the second gear 1003 and the mounting shaft 1004 causes the mounting shaft 1004 and the connecting frame 1701 to rotate. When the connecting frame 1701 rotates, it drives the first slider 1702 and the second slider 1703 to move along a specific trajectory on the guide frame 1705, thus ensuring that the circular saw 15 performs efficient cutting only within a suitable working area. After the secondary cutting is completed, the initial height of the circular saw 15 is adjusted by extending or shortening the electric push rod 2, so that the grinding ring 16 fits against the cutting surface. By connecting the switching component 11 to the mounting shaft 1004, the rotation of the mounting shaft 1004 acts on the switching component 11. At this time, as... Figure 7 As shown, the guide component 17 enables the circular saw 15 to move left and right along a specific trajectory, and the switching component 11 enables the circular saw 15 to move back and forth. When the grinding ring 16 abuts against the cutting surface and rotates, the function of grinding the cutting surface can be realized. When the blade of the circular saw 15 becomes dull, the rotational resistance of the mounting shaft 1004 increases, thereby causing the mounting shaft 1004 to stop rotating. When the grinding ring 16 abuts against the cutting surface and cannot move further towards the cutting surface, the rotational resistance of the mounting shaft 1004 also increases, thereby causing the second gear 1003 to slide on the mounting shaft 1004. At this time, the circular saw 15 stops moving, realizing targeted grinding of local positions of the cutting surface.

[0025] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. like Figure 1 As shown, in a preferred embodiment, based on the above method, a second connecting shaft 6 is further provided on one side of the first connecting shaft 4. The first connecting shaft 4 and the second connecting shaft 6 are rotatably connected to the base 1. A first groove 8 is provided on the base 1. The first connecting shaft 4 and the second connecting shaft 6 facilitate subsequent pressing and fixing of both sides of the transformer core 7. The first groove 8 makes the cutting operation space of the device larger.

[0026] like Figures 2-4 , Figure 13 and Figure 14As shown, in a preferred embodiment, based on the above method, the fixing component 5 further includes a first bidirectional screw 501 fixedly connected to the first connecting shaft 4, a second bidirectional screw 502 mounted on the second connecting shaft 6, a fourth synchronous pulley 27 rotatably connected to the outer side of the second connecting shaft 6, an outer bushing 503 threadedly connected to the outer sides of both the first bidirectional screw 501 and the second bidirectional screw 502, a clamping plate 504 and a support plate 505 fixedly mounted on the outer bushing 503, a locking block 507 slidably mounted on both the first connecting shaft 4 and the second connecting shaft 6, a first spring 508 installed between the locking block 507 and both the first connecting shaft 4 and the second connecting shaft 6, and a second synchronous belt 28 installed between the third synchronous pulley 26 and the fourth synchronous pulley 27. Figures 2-4 , Figure 13 and Figure 14 As shown, the first spring 508 on the first connecting shaft 4 keeps the outer wall of the locking block 507 in contact with the third synchronous wheel 26, causing the third synchronous wheel 26 to rotate. When the third synchronous wheel 26 rotates, it drives the fourth synchronous wheel 27 to rotate through the second synchronous belt 28. The third synchronous wheel 26 and the fourth synchronous wheel 27 drive the first bidirectional screw 501 and the second bidirectional screw 502 to rotate. The first bidirectional screw 501 and the second bidirectional screw 502 drive the two sets of clamping plates 504 and support plates 505 on both sides of the base 1 to move closer to each other. When the two sets of support plates 505 move closer to each other, they press and fix the two sides of the transformer core 7. After pressing, the two sets of support plates 505 cannot move further, the rotational resistance of the third synchronous wheel 26 increases, and the third synchronous wheel 26 will slide on the outside of the first connecting shaft 4. The first spring 508 on the locking block 507 is intermittently compressed.

[0027] like Figures 2-4 , Figure 13 and Figure 14 As shown, in a preferred embodiment, based on the above method, the support plate 505 is further provided with a first oblique surface 506, the cutting surfaces of the first oblique surfaces 506 on two adjacent support plates 505 are oriented in opposite directions, the threads of the first bidirectional screw 501 and the second bidirectional screw 502 are oriented in opposite directions, and the third synchronous wheel 26 and the fourth synchronous wheel 27 are each provided with a first slot 509 for docking with the locking block 507. The outer wall of the locking block 507 is in close contact with the inner wall of the first slot 509, and the side of the locking block 507 near the first slot 509 is an arc surface. When the first oblique surface 506 on the support plate 505 abuts against the transformer core 7, it will automatically lift the transformer core 7, thereby avoiding damage to the base 1 by the circular saw 15 during subsequent cutting. The locking block 507 and the first slot 509 can achieve a flexible locking function.

[0028] like Figure 6 , Figure 7 and Figure 11As shown, in a preferred embodiment, based on the above method, the first connecting shell 9, the connecting post 1704 and the connecting frame 1701 are further fixedly connected as an integral structure. The connecting post 1704 is symmetrically distributed on both sides of the first connecting shell 9. There are gaps between the lower half of the connecting post 1704 and the guide frame 1705 and the first connecting shell 9. The gaps allow the connecting frame 1701 to rotate so that the connecting frame 1701 and the first slider 1702 can move along a specific trajectory. Thus, two cuts are completed through a single cutting structure, achieving efficient production of two C-shaped magnetic cores.

[0029] like Figures 4-10 As shown, in a preferred embodiment, based on the above method, the mounting shaft 1004 and the second gear 1003 are rotatably connected, and the second gear 1003 and the first gear 1002 are rotatably connected to the first connecting shell 9. A second groove 1005 is provided in the mounting shaft 1004, and a second spring 1007 is installed in the second groove 1005. A support block 1006 is fixedly provided on the second spring 1007. A docking groove 1008 for docking with the support block 1006 is provided on the second gear 1003. The side of the support block 1006 away from the mounting shaft 1004 and the central axis is an arc surface. The first gear 1002 and the second gear 1003 are rotatably connected. The 003 can rotate stably within the first connecting shell 9. The second spring 1007 causes the outer wall of the support block 1006 to abut against the inner wall of the docking groove 1008, keeping the second gear 1003 and the mounting shaft 1004 in a flexible engagement state. Subsequently, when the blade of the circular saw 15 becomes dull, the resistance to the mounting shaft 1004 continuing to drive the circular saw 15 to move increases, the support block 1006 contracts after being compressed, the second spring 1007 is compressed, and the second gear 1003 slides on the mounting shaft 1004. At this time, although the circular saw 15 rotates, it stops moving further, realizing the function of slow movement after the circular saw 15 becomes dull, realizing the overload protection function, and enhancing the safety of the device during use.

[0030] like Figures 4-10 As shown, in a preferred embodiment, based on the above method, the switching assembly 11 further includes a first synchronous pulley 1101 rotatably mounted on the mounting shaft 1004. A first keyway 1104 is formed inside the first synchronous pulley 1101. A key block 1103 is provided on the side of the first synchronous pulley 1101. A first key rod 1102 is mounted on the key block 1103. A second keyway 1105 and a guide groove 1106 are formed on the mounting shaft 1004. A first synchronous belt 1107 is provided on the outer side of the first synchronous pulley 1101. A second synchronous pulley 1108 is mounted on the first synchronous belt 1107. A third screw 1109 is connected to the second synchronous pulley 1108. The third screw 1109 is threadedly connected to the connecting block 12. Figure 8As can be seen, the cross-sectional area of ​​the key block 1103 decreases from the side closest to the first key rod 1102 to the side furthest from the first key rod 1102. Similarly, the cross-sectional area of ​​the guide groove 1106 decreases from the side closest to the first key rod 1102 to the side furthest from the first key rod 1102. Therefore, the key block 1103, in conjunction with the guide groove 1106, can achieve a guiding function, allowing the first key rod 1102 to achieve a key connection function without precise alignment with the first key groove 1104 and the second key groove 1105. This enables the switching of the power for the transverse moving circular saw 15 to the forward and backward moving circular saw 15, facilitating subsequent grinding of the cut surface.

[0031] like Figure 7 As shown, in a preferred embodiment, based on the above method, a side plate 18 and a guide rail 24 are further installed on the connecting column 1704. A cross bar 19 is welded on the side plate 18. A slide bar 21 is slidably installed on the outside of the cross bar 19. A handle 23 is installed on the slide bar 21. The connecting block 12 is slidably installed on the outside of the guide rail 24. When the device is in use, the slide bar 21 can be pushed by holding the handle 23, so that the slide bar 21 can slide horizontally through the cross bar 19, so that the moving cutting can be switched to grinding later.

[0032] like Figure 1 , Figure 6 , Figure 7 and Figure 11 As shown, in a preferred embodiment, based on the above method, a U-shaped groove 1706 for guiding the second slider 1703 is further provided on the guide frame 1705. A stop block 25 is fixedly connected to the guide frame 1705. The stop block 25 is not connected to the second connecting shell 13. The second connecting shell 13 is only connected to the guide frame 1705 as shown in the figure. Figure 9 When in the initial position shown, it is in contact with the stop 25. The U-shaped groove 1706 on the guide frame 1705 ensures that the circular saw 15 inside the second connecting shell 13 can move along the U-shaped trajectory, ensuring that the device completes the production steps of the C-shaped magnetic core in a suitable cutting work space.

[0033] like Figure 12 As shown, in a preferred embodiment, based on the above method, a damping pad 20 is further installed on the cross bar 19, and a moving groove 22 is opened on the slide bar 21. The damping pad 20 is in frictional contact with the inner wall of the moving groove 22 to ensure that the slide bar 21 can always be pressed by the damping pad 20. After the slide bar 21 moves to a suitable position, it can remain fixed. During the production of magnetic cores, it can remain stable after the cutting is switched to grinding.

[0034] Example 3: The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods. Specifically, when using this magnetic core production equipment: (e.g.) Figures 1-10 As shown, the transformer core 7 is placed on the first groove 8 of the base 1, and the third synchronous wheel 26 is driven to rotate by the first motor 3. This, combined with the fixing assembly 5, allows the transformer core 7 to automatically clamp after being lifted. Figures 2-4 , Figure 13 and Figure 14 As shown, the specific working process of the fixing component 5 is as follows: the third synchronous pulley 26 drives the fourth synchronous pulley 27 to rotate synchronously through the second synchronous belt 28. The third synchronous pulley 26 and the fourth synchronous pulley 27 respectively drive the first connecting shaft 4 and the second connecting shaft 6 to rotate. The first bidirectional screw 501 and the second bidirectional screw 502 have opposite rotation directions. Therefore, the outer bushing 503 of the drive thread connection moves towards each other. Figure 4 The arrows indicate the moving direction of each set of clamping plates 504 and support plates 505 (which can realize the clamping function of transformer core 7). Since the support plate 505 has a first oblique surface 506, when the two sets of support plates 505 move towards each other, the first oblique surface 506 contacts the side of the core and lifts it upward until the clamping plate 504 and support plate 505 jointly press the core. After the pressing is completed, the transmission resistance increases, which causes the locking block 507 installed on the first connecting shaft 4 and the second connecting shaft 6 to compress the first spring 508. The locking block 507 slides out from the first locking groove 509 on the third synchronous wheel 26 and the fourth synchronous wheel 27, thereby realizing transmission disengagement and overload protection, ensuring that the device automatically clamps both sides of the transformer core 7 after lifting, and realizes the function of fixing the transformer core 7 in the center.

[0035] like Figures 6-12 As shown, during cutting, the electric push rod 2 is first extended, driving the first connecting shell 9, connecting column 1704, and guide frame 1705 to move downwards. The third motor 14 then drives the circular saw 15 to rotate, completing the first cut of the transformer core 7. Because the transformer core 7 is a flat O-shape, after one cut, as shown... Figure 9 and Figure 10As shown, by shortening the electric push rod 2 and adjusting the switching component 11, the drive component 10 can not only act on the circular saw 15, but also adjust the initial position of the second connecting shell 13. The adjustment process of the switching component 11 is as follows: hold the handle 23 and push the slide rod 21 connected to it. The slide rod 21 slides in the moving groove 22 and drives the cross rod 19 to move. The cross bar 19 pushes the key block 1103 and the first key bar 1102, so that the first key bar 1102 is simultaneously embedded in the first keyway 1104 on the first synchronous pulley 1101 and the second keyway 1105 on the mounting shaft 1004. The torque of the mounting shaft 1004 can be transmitted to the second synchronous pulley 1108 through the first synchronous pulley 1101 and the first synchronous belt 1107. The second synchronous pulley 1108 drives the third screw 1109 to rotate. Since the third screw 1109 is threadedly connected to the connecting block 12, and the connecting block 12 is slidably mounted on the guide rail 24, under the guidance of the guide rail 24, the second connecting shell 13 and the circular saw 15 on it move back and forth along the guide rail 24, thereby adjusting the cutting surface of the circular saw 15 to be symmetrical with the first cutting position. After the adjustment is in place, the handle 23 is reversed to reset the switching component 11, and the first key bar 1102 disengages from the keyway for a second cut, thereby cutting the O-type transformer core 7 into two C-type transformer cores 7 of specific lengths.

[0036] During cutting, the device can cut along a specific trajectory, thereby increasing the cutting range. Figures 5-7 As shown, the second motor 1001 drives the first gear 1002 to rotate, and the first gear 1002 drives the second gear 1003 to rotate. The friction between the second gear 1003 and the mounting shaft 1004 causes the mounting shaft 1004 and the connecting frame 1701 to rotate. Specifically, as shown... Figure 8 and Figure 10 As shown, the support block 1006, under the elastic force of the second spring 1007, engages in the mating groove 1008 on the end face of the second gear 1003, thereby achieving torque transmission. When the mounting shaft 1004 and the connecting frame 1701 rotate, the connecting frame 1701 drives the first slider 1702 and the second slider 1703 to move along the trajectory of the U-shaped groove 1706 on the guide frame 1705, thereby ensuring that the circular saw 15 performs efficient cutting work only within a suitable working area. Combined with the lifting structure for the transformer core 7, this reduces the lateral space occupied during the cutting operation. After the secondary cutting is completed, the initial height of the circular saw 15 is adjusted by extending or shortening the electric push rod 2, so that the grinding ring 16 fits against the cutting surface. By connecting the switching assembly 11 to the mounting shaft 1004, the rotation of the mounting shaft 1004 acts on the switching assembly 11. At this time, as... Figure 7As shown, the guide component 17 enables the circular saw 15 to move left and right along a specific trajectory, and the switching component 11 enables the circular saw 15 to move back and forth. When the grinding ring 16 abuts against the cutting surface and rotates, the function of grinding the cutting surface can be realized. When the blade of the circular saw 15 becomes dull, the rotational resistance of the mounting shaft 1004 increases, thereby causing the mounting shaft 1004 to stop rotating. When the grinding ring 16 abuts against the cutting surface and cannot move further towards the cutting surface, the rotational resistance of the mounting shaft 1004 also increases, thereby causing the second gear 1003 to slide on the mounting shaft 1004. At this time, the circular saw 15 stops moving, realizing targeted grinding of local positions of the cutting surface.
