Description

Technical Field

[0001] This utility model belongs to the field of iron core cutting technology, specifically relating to a flexible clamping and positioning device for iron core cutting. Background Technology

[0002] The iron core is a magnetically conductive component in electrical equipment used to guide and concentrate magnetic flux. It is a core component of electromagnetic devices such as transformers, motors, and inductors. The main function of the iron core is to provide a low magnetic reluctance path for the magnetic field, guiding and concentrating magnetic flux through its interior, thereby improving the utilization rate of magnetic flux and achieving efficient conversion between electrical and magnetic energy. This enhances equipment efficiency and reduces energy consumption. Iron core cutting is a crucial process in iron core manufacturing and subsequent processing. Its core principle is to precisely separate the iron core material according to the design dimensions while minimizing damage to its magnetic conductivity.

[0003] In the existing technology, when cutting iron cores, it is necessary to cut iron cores of different sizes, which causes traditional clamping devices to frequently disassemble the insert rods and shims to adjust the position of the clamping blocks to adapt to different sizes. This operation is time-consuming, has low switching efficiency, poor adaptability, and poor practicality. Utility Model Content

[0004] This utility model provides a flexible clamping and positioning device for iron core cutting, which aims to solve the problem of low switching efficiency caused by the need for existing clamping devices to adapt to iron cores of different sizes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a flexible clamping and positioning device for iron core cutting, comprising: frame; Two limiting mechanisms are provided, both of which are slidably mounted on the frame. Each limiting mechanism has a vertical abutment surface and a limiting part located at the bottom of the vertical abutment surface. The spacing direction between the two limiting mechanisms is defined as a first direction, and the direction perpendicular to the first direction and horizontal is defined as a second direction. The limiting part is slidably mounted along the second direction to jointly limit and clamp the pre-positioned iron core with the corresponding vertical abutment surface. A cutting gap is formed between the two vertical abutment surfaces. Each clamping mechanism has multiple telescopic ends, and each telescopic end can extend along the second direction toward each limiting mechanism and abut against the iron core to clamp the iron core.

[0006] In one possible implementation, the rack includes: The mounting bracket has two slide rails; Two connecting slides are provided, and each connecting slide is slidably disposed on the two slide rails along the second direction; A drive structure is poweredly connected to one of the connecting slides to drive the corresponding connecting slide to slide along the second direction.

[0007] In one possible implementation, each of the limiting mechanisms includes: A limiting slide block is slidably disposed on the connecting slide block that is not connected to the driving structure along the first direction; A limiting abutment block is fixedly mounted on the limiting slide block. The limiting abutment block has a horizontal section and a vertical section. The horizontal section of the limiting abutment block is fixedly mounted on the limiting slide block. The bottom end of the vertical section of the limiting abutment block is integrally connected to the horizontal section of the limiting abutment block. The top end of the vertical section of the limiting abutment block extends upward in the vertical direction. The side wall of the vertical section of the limiting abutment block is the vertical abutment surface. A limiting plate is provided along the second direction, one end of which is fixed on the horizontal section of the limiting abutment block, and the other end of which extends along the second direction toward another limiting slide block; A limiting slider is slidably disposed on the limiting plate along the second direction, and the limiting slider is the limiting part; The corresponding connecting slide is provided with a limiting track for each limiting slide to slide.

[0008] In one possible implementation, the limiting abutment block is provided with a limiting reinforcing plate, which connects the horizontal section and the vertical section of the limiting abutment block.

[0009] In one possible implementation, two clamping mechanisms are provided, each clamping mechanism corresponding to one of the two limiting mechanisms. Each clamping mechanism and its corresponding limiting mechanism are spaced apart along the second direction. Each clamping mechanism includes: A clamping slide is slidably disposed on the connecting slide that connects to the driving structure along the first direction; A clamping connecting block is fixed on the clamping slide. The clamping connecting block has a horizontal section and a vertical section. The horizontal section of the clamping connecting block is fixed on the clamping slide. The bottom end of the vertical section of the clamping connecting block is integrally connected to the horizontal section of the clamping connecting block. The top end of the vertical section of the clamping connecting block extends upward in the vertical direction. The telescopic structure is provided in multiple ways. The fixed end of each telescopic structure is fixed on the vertical section of the clamping connecting block, and the telescopic end of each telescopic structure extends out toward another connecting slide along the second direction.

[0010] In one possible implementation, the clamping connecting block is provided with a clamping reinforcing plate, which connects the horizontal section of the clamping connecting block and the vertical section of the clamping connecting block.

[0011] In one possible implementation, the two clamping connecting blocks are correspondingly arranged with the two limiting abutment blocks, and each clamping connecting block is provided with a limiting sliding hole through which the corresponding limiting plate passes along the second direction.

[0012] In one possible implementation, each of the telescopic structures has a flexible abutment piece on its telescopic end.

[0013] In one possible implementation, the telescopic structure is a hydraulic push rod.

[0014] In this implementation, compared with existing technologies, the limiting mechanism can slide along the frame, and the limiting part can slide along the second direction. Without disassembling the insert rod and shims, the distance between the two limiting mechanisms and the distance between the limiting part and the vertical contact surface can be adjusted, shortening the size changeover time and improving production efficiency. A cutting gap is formed between the two vertical contact surfaces, providing a working channel for the cutting tool, ensuring accurate cutting paths, reducing cutting errors, and improving processing quality. Multiple telescopic ends of the clamping mechanism abut against the iron core along the second direction, forming multi-point clamping. Combined with the limiting mechanism's limiting function, the iron core is fixed in multiple directions, preventing offset and vibration during cutting, ensuring cutting accuracy, and reducing the damage to the iron core's magnetic conductivity caused by vibration. The structural design is universal; by adjusting the positions of the limiting part and telescopic ends, it can adapt to irregularly shaped and special-sized iron cores, improving the device's adaptability and practicality, and meeting diverse production needs.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] It should be noted that the terms "length", "width", "height", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "head", and "tail" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0018] It should also be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a structure. They can refer to a mechanical connection or an electrical connection.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0020] Please refer to the following: Figures 1 to 4The flexible clamping and positioning device for iron core cutting provided by this utility model will now be described. The flexible clamping and positioning device for iron core cutting includes a frame 10, a limiting mechanism 20, and a clamping mechanism 30. Two limiting mechanisms 20 are provided, both slidably mounted on the frame 10. Each limiting mechanism 20 has a vertical abutment surface and a limiting portion located at the bottom of the vertical abutment surface. The spacing direction between the two limiting mechanisms 20 is defined as a first direction, and the direction perpendicular to and horizontal to the first direction is defined as a second direction. The limiting portion is slidably mounted along the second direction to clamp and limit the pre-positioned iron core together with the corresponding vertical abutment surface. A cutting slit is formed between the two vertical abutment surfaces. Each clamping mechanism 30 has multiple telescopic ends, each of which can extend along the second direction toward each limiting mechanism 20 and abut against the iron core to clamp it.

[0021] The flexible clamping and positioning device for iron core cutting provided in this embodiment, compared with the prior art, allows the limiting mechanism 20 to slide along the frame 10 and the limiting part to slide along the second direction. Without disassembling the insert rod and shims, the distance between the two limiting mechanisms 20 and the distance between the limiting part and the vertical contact surface can be adjusted, shortening the size changeover time and improving production efficiency. A cutting slit is formed between the two vertical contact surfaces, providing a working channel for the cutting tool, ensuring accurate cutting paths, reducing cutting errors, and improving processing quality. The clamping mechanism has more than 30 telescopic ends that abut against the iron core along the second direction, forming multi-point clamping. Combined with the limiting mechanism 20, this achieves multi-directional fixation of the iron core, preventing offset and vibration during cutting, ensuring cutting accuracy, and reducing the damage of vibration to the magnetic conductivity of the iron core. The structural design is universal; by adjusting the positions of the limiting part and telescopic ends, it can adapt to irregularly shaped and special-sized iron cores, improving the device's adaptability and practicality, and meeting diverse production needs.

[0022] In some embodiments, the rack 10 described above may be as follows: Figure 1 , Figure 3 , Figure 4 The structure shown. See also Figure 1 , Figure 3 , Figure 4 The frame 10 includes a fixed frame 11, a connecting slide 12, and a drive structure 13. The fixed frame 11 has two slide rails. There are two connecting slides 12, each of which is slidably mounted on the two slide rails along a second direction. The drive structure 13 is poweredly connected to one of the connecting slides 12 and is used to drive the corresponding connecting slide 12 to slide along the second direction.

[0023] Two connecting slides 12 respectively support the limiting mechanism 20 and the clamping mechanism 30. The drive structure 13 drives one of the connecting slides 12 to slide, allowing for quick adjustment of the distance between the two connecting slides 12. This enables position adjustment of the limiting mechanism 20 and the clamping mechanism 30 in the second direction, accommodating iron cores of different dimensions in the second direction. Adjustment requires no manual pushing, resulting in a high degree of automation, convenient operation, and high efficiency. The drive structure 13 is poweredly connected to the connecting slide 12, allowing for precise control of the moving speed and position of the connecting slide 12. The positioning accuracy is higher than traditional manual adjustment, reducing clamping instability caused by positional deviations and improving cutting accuracy. The frame 10 has a reasonable structure, and the fixed frame 11 is made of high-strength material, ensuring the device's load-bearing capacity and structural stability, withstanding cutting vibrations and impacts, and extending its service life.

[0024] In some embodiments, the limiting mechanism 20 may employ, for example, Figures 1 to 4 The structure shown. See also Figures 1 to 4 Each limiting mechanism 20 includes a limiting slide 21, a limiting abutment block 22, a limiting plate 23, and a limiting slider 24. The limiting slide 21 is slidably mounted on the connecting slide 12, which is not connected to the driving structure 13, along a first direction. The limiting abutment block 22 is fixed on the limiting slide 21 and has a horizontal section and a vertical section. The horizontal section of the limiting abutment block 22 is fixed on the limiting slide 21, and the bottom end of the vertical section of the limiting abutment block 22 is integrally connected to the horizontal section of the limiting abutment block 22. The top end of the vertical section of the limiting abutment block 22 extends upward along the vertical direction, and the side wall of the vertical section of the limiting abutment block 22 is a vertical abutment surface. The limiting plate 23 is arranged along a second direction. One end of the limiting plate 23 is fixed on the horizontal section of the limiting abutment block 22, and the other end of the limiting plate 23 extends towards another limiting slide 21 along the second direction. The limiting slider 24 is slidably disposed on the limiting plate 23 along the second direction, and the limiting slider 24 is the limiting part.

[0025] The corresponding connecting slide 12 is provided with a limiting track for each limiting slide 21 to slide.

[0026] The limiting slide block 21 is slidably mounted on the limiting track connecting the slide block 12 along the first direction. The distance between the two limiting abutment blocks 22 can be adjusted to accommodate iron cores of different sizes in the first direction. Adjustment does not require disassembly of parts, making operation convenient and improving the efficiency of size switching. The limiting abutment block 22 is an integrated structure of horizontal and vertical sections. The horizontal section is fixed to the limiting slide block 21 to ensure installation stability. The side wall of the vertical section is a vertical abutment surface that fits against the side wall of the iron core, providing lateral limiting and preventing the iron core from shifting in the first direction. The limiting plate 23 is set along the second direction and fixed to the horizontal section of the limiting abutment block 22. The limiting slider 24 is slidably mounted on the limiting plate 23 along the second direction. The distance between the limiting slider 24 and the vertical abutment surface can be adjusted to accommodate iron cores of different sizes in the second direction. At the same time, the limiting slider 24 and the vertical abutment surface form a bidirectional clamping effect on the bottom of the iron core, improving the positioning stability in the second direction. The limiting block 22 is integrally formed and the limiting plate 23 is fixedly connected to ensure the structural strength of the limiting mechanism 20, withstand cutting vibration and impact, avoid structural deformation leading to positioning deviation, and improve processing accuracy.

[0027] In some embodiments, the aforementioned limiting abutment block 22 may be adopted as follows: Figures 1 to 4 The structure shown. See also Figures 1 to 4 The limiting abutment block 22 is provided with a limiting reinforcing plate 221, which connects the horizontal section and the vertical section of the limiting abutment block 22.

[0028] During the cutting process, the iron core exerts lateral pressure on the vertical contact surface, and the cutting vibration impacts the limiting contact block 22. Long-term use can easily lead to stress concentration, deformation, or breakage at the connection between the horizontal and vertical sections. The limiting reinforcement plate 221 can disperse the stress at the connection, enhance the overall structural strength and rigidity of the limiting contact block 22, avoid deformation caused by lateral pressure and vibration, and ensure the flatness and perpendicularity of the vertical contact surface, providing structural protection for the precise positioning of the iron core. Deformation of the limiting contact block 22 can cause the vertical contact surface to shift, affecting the clamping and positioning accuracy and causing cutting errors. The limiting reinforcement plate 221, by enhancing structural strength, suppresses the deformation of the limiting contact block 22, ensuring that the vertical contact surface maintains its preset position, ensuring the consistency and accuracy of clamping and positioning, and improving the cutting quality. The limiting reinforcement plate 221 can reduce wear and fatigue damage to the limiting contact block 22, extend its service life, and reduce equipment maintenance costs and replacement frequency.

[0029] In some embodiments, the clamping mechanism 30 may employ, for example... Figures 1 to 4 The structure shown. See also Figures 1 to 4Two clamping mechanisms 30 are provided, each corresponding to one of the two limiting mechanisms 20. Each clamping mechanism 30 and its corresponding limiting mechanism 20 are spaced apart along a second direction. Each clamping mechanism 30 includes a clamping slide 31, a clamping connecting block 32, and a telescopic structure 33. The clamping slide 31 is slidably mounted on the connecting slide 12 of the connecting drive structure 13 along a first direction. The clamping connecting block 32 is fixed to the clamping slide 31 and has a horizontal section and a vertical section. The horizontal section of the clamping connecting block 32 is fixed to the clamping slide 31, and the bottom end of the vertical section of the clamping connecting block 32 is integrally connected to the horizontal section. The top end of the vertical section of the clamping connecting block 32 extends upwards along the vertical direction. Multiple telescopic structures 33 are provided. The fixed end of each telescopic structure 33 is fixed to the vertical section of the clamping connecting block 32, and the telescopic end of each telescopic structure 33 extends towards another connecting slide 12 along the second direction.

[0030] The combination of clamping slide 31, clamping connecting block 32, and multiple telescopic structures 33 enhances the clamping stability and adaptability of the device. The clamping slide 31 slides along the first direction on the connecting slide 12 of the connecting drive structure 13. The position of the clamping mechanism 30 can be adjusted, coordinating with the limiting mechanism 20 to precisely adapt to iron cores of different dimensions in the first direction. This ensures that the telescopic end of the telescopic structure 33 accurately abuts against the corresponding position of the iron core, achieving reliable clamping. The clamping connecting block 32 is an integrated structure of horizontal and vertical sections. The horizontal section is fixed to the clamping slide 31 for stable installation. The vertical section provides the installation foundation for the telescopic structure 33, ensuring that the telescopic structure 33 does not shake or shift during operation, and ensuring stable transmission of clamping force. Compared to the traditional single-clamping-point design, multiple telescopic structures 33 can clamp the iron core from different positions, forming multi-point fixation, dispersing clamping stress, avoiding excessive local pressure that could lead to iron core deformation or surface damage, while also improving the stability of the iron core during cutting, preventing shifting and vibration, and ensuring cutting accuracy.

[0031] In some embodiments, the clamping connecting block 32 may be adopted as follows: Figures 1 to 4 The structure shown. See also Figures 1 to 4 The clamping connecting block 32 is provided with a clamping reinforcing plate 311, which connects the horizontal section and the vertical section of the clamping connecting block 32.

[0032] The clamping reinforcement plate 311 disperses the stress generated by the reaction force, enhances the overall structural strength and rigidity of the clamping connecting block 32, prevents deformation or damage at the connection point, and ensures the structural stability of the clamping connecting block 32. Deformation of the clamping connecting block 32 can cause the installation position of the telescopic structure 33 to shift, resulting in a deviation in the direction of the contact force at the telescopic end, affecting the clamping positioning accuracy, and even causing the iron core to tilt or shift, thus affecting the cutting accuracy. By suppressing the deformation of the clamping connecting block 32, the clamping reinforcement plate 311 ensures that the telescopic structure 33 maintains the preset installation angle and position, ensures that the direction of the contact force at the telescopic end is consistent with the second direction, ensures the accuracy of clamping positioning, and improves the cutting quality. The clamping reinforcement plate 311 can reduce fatigue damage to the clamping connecting block 32, extend its service life, and reduce equipment maintenance costs and replacement frequency.

[0033] In some embodiments, the clamping connecting block 32 may be adopted as follows: Figures 1 to 4 The structure shown. See also Figures 1 to 4 Two clamping connecting blocks 32 are correspondingly set with two limiting abutment blocks 22, and each clamping connecting block 32 is provided with a limiting sliding hole for the corresponding limiting plate 23 to pass through along the second direction.

[0034] Two clamping connecting blocks 32 are correspondingly arranged with two limiting abutment blocks 22, making the spatial layout of the limiting mechanism 20 and the clamping mechanism 30 reasonable. This ensures that the limiting plate 23 accurately passes through the limiting sliding hole, avoids spatial interference between the limiting plate 23 and the clamping connecting blocks 32, ensures smooth adjustment of the limiting slider 24 in the second direction, and improves operational convenience. The limiting sliding hole plays an auxiliary guiding role for the limiting plate 23, ensuring the straightness of the limiting plate 23's movement in the second direction, thereby ensuring the positional accuracy of the limiting slider 24 and improving the clamping and positioning accuracy of the iron core in the second direction. The gap between the limiting sliding hole and the limiting plate 23 is controlled within a reasonable range, ensuring smooth movement while limiting the lateral sway of the limiting plate 23, enhancing the stability of the limiting mechanism 20, and preventing positioning deviations caused by the swaying of the limiting plate 23 during cutting.

[0035] In some embodiments, the telescopic structure 33 may adopt the following... Figures 1 to 4 The structure shown. See also Figures 1 to 4 Each telescopic structure 33 has a flexible abutment piece on its telescopic end.

[0036] The flexible abutment plate, made of flexible material, avoids scratching or indenting the core surface compared to traditional rigid abutment surfaces, protecting the core surface quality and ensuring that the core's magnetic conductivity is not affected by surface damage. The flexible abutment plate has elasticity and anti-slip properties; the anti-slip texture on the surface increases friction with the core surface, preventing the core from slipping during cutting and improving clamping stability. The elastic material adapts to minor unevenness on the core surface, ensuring a tight fit between the abutment plate and the core surface, enhancing the clamping effect. The flexible abutment plate also has a buffering effect, absorbing some clamping stress and cutting vibration, reducing stress concentration inside the core caused by rigid clamping, preventing core deformation, and reducing the damage to the core's magnetic conductivity caused by vibration.

[0037] In some embodiments, the telescopic structure 33 may adopt the following... Figures 1 to 4 The structure shown. See also Figures 1 to 4 The telescopic structure 33 is a hydraulic push rod.

[0038] The hydraulic push rod boasts high thrust and stable output force, providing sufficient clamping force to meet the clamping needs of iron cores of varying thicknesses and materials. Even large-sized, heavy iron cores can be firmly clamped, preventing loosening during cutting. The extension stroke of the hydraulic push rod is adjustable, with precise control of the extension length via the hydraulic system, adapting to iron cores of different secondary dimensions. High adjustment accuracy ensures precise clamping and positioning. The hydraulic push rod operates smoothly with minimal start-stop impact, preventing vibration or displacement of the iron core caused by sudden changes in clamping force. The hydraulic system has buffering properties, absorbing some cutting vibration and improving clamping stability. The hydraulic push rod has a reliable structure, long service life, and low maintenance costs, making it suitable for long-term, high-intensity production environments and meeting the needs of industrial mass production.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
