Description

Technical Field

[0001] This utility model relates to the field of inductor coil technology, and specifically to a spiral inductor coil winding fixture. Background Technology

[0002] An inductor winding fixture is a specialized tooling device used in the inductor winding process. It aims to improve the production efficiency and quality of inductors. A search revealed that patent publication number CN220189430U discloses a filter inductor winding fixture. While this device can rotate the filter inductor winding via the first and second end frames, the rigid clamping of the first and second end frames during use may not be adaptable to inductors of different sizes and shapes, limiting the fixture's versatility and flexibility. Furthermore, rigid clamping can cause uneven stress on the coil during winding, affecting its electrical performance and physical structural stability. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a spiral inductor coil winding fixture, which solves the problems mentioned in the background art.

[0004] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0005] A spiral inductor coil winding fixture includes a left fixing component and a right fixing component mounted on a base, the left fixing component and the right fixing component fixing the coil base.

[0006] The base is provided with a base plate, and a sliding groove is provided on the base plate. A left fixing component is installed on the base plate through the sliding groove. A right side plate is welded to the end of the base plate opposite to the left fixing component. A right fixing component is installed on the base plate through the right side plate.

[0007] The right fixing component is provided with a guide rod, on which a second rubber cone is movably mounted. A bushing is installed on the guide rod. The right fixing component is rotatably mounted on the right side plate via the bushing. A spring is installed between the guide rod and the second rubber cone and the bushing. The left fixing component is provided with a left side plate, on which a first rubber cone is rotatably mounted. The coil base is clamped and fixed by the first rubber cone and the second rubber cone.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the base has a support plate at its bottom end, and the base plate has reinforcing ribs at the connection between the base plate and the right side plate.

[0010] The beneficial effects of adopting the above-mentioned further solutions are:

[0011] The support plate at the bottom of the base provides a larger support surface for the entire fixture, reducing tilting or instability caused by insufficient contact area. Especially during winding, the equipment may be subjected to lateral forces from rotation or external operation; the support plate effectively disperses these forces, preventing the equipment from tipping over or sliding, ensuring operational safety and stability. Reinforcing ribs are located at the connection between the base plate and the right side plate, increasing rigidity by adding material thickness or shape complexity to this area. This design effectively prevents bending or deformation at the connection between the base plate and the right side plate. Particularly under heavy loads or continuous operation, the presence of the reinforcing ribs maintains the fixture's geometry, ensuring stability under high loads.

[0012] Furthermore, a limiting plate is provided at the bottom of the left side plate, and the left fixing component is limited and locked to the sliding groove of the base by the left side plate and the limiting plate. A connecting plate is provided at the bottom of the limiting plate, and the connecting plate is connected and fixed to the output end of the cylinder.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The limiting plate at the bottom of the left side plate serves for precise positioning. By engaging the limiting plate within the slide groove of the base, the position of the left fixing component on the fixture is ensured to remain stable and prevent displacement during operation. This design guarantees that the clamping position of the coil base remains precise, contributing to improved winding consistency and accuracy. The left fixing component, secured in the slide groove by the left side plate and the limiting plate, allows for sliding adjustment along the groove as needed. This design allows operators to quickly adjust the position of the left fixing component according to different coil base sizes or process requirements, enhancing the adaptability of the fixture and operational flexibility. The connecting plate at the bottom of the limiting plate is connected and fixed to the output end of the cylinder, enabling automated clamping of the left fixing component via the cylinder's thrust. The cylinder provides a stable and adjustable clamping force, and the clamping force and speed can be precisely adjusted via pneumatic control. This is more labor-saving and uniform than manual clamping, making it particularly suitable for winding operations requiring high repeatability and efficiency.

[0015] Furthermore, the cylinder is located on the bottom surface of the base plate, and the cylinder is located between the support plates of the base plate.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] By mounting the cylinder on the bottom surface of the base plate, between the base plate and the support plate, the cylinder can be effectively protected from external mechanical impacts or interference during operation. The support plate provides additional protection for the cylinder, reducing the risk of damage that may occur due to the cylinder's exposure to the external environment.

[0018] Furthermore, a crank is installed at the end of the guide rod, and a handle is installed on the crank.

[0019] The beneficial effects of adopting the above-mentioned further solutions are:

[0020] The handle design makes manual operation more comfortable. The crank provides a longer operating lever, which reduces the force required for each operation, lowers the labor intensity, and improves user comfort. Furthermore, the handle design allows operators to operate for extended periods more easily. The crank's mechanical structure helps distribute the applied force, reducing hand fatigue during operation.

[0021] Furthermore, the left side plate and the first rubber cone have through holes, and the size of the through holes is adapted to the size of the guide rod. The left side plate and the first rubber cone are slidably mounted on the guide rod to achieve the effect of clamping and fixing the coil base through the first rubber cone and the second rubber cone.

[0022] The beneficial effects of adopting the above-mentioned further solutions are:

[0023] The size of the through-hole is matched to the diameter of the guide rod, allowing the left side plate and the first rubber cone to slide smoothly on the guide rod. This precise fit ensures that the left side plate and the first rubber cone can slide evenly on the guide rod, avoiding instability or positional displacement caused by improper fit. Through the sliding installation design of the through-hole, the first rubber cone and the left side plate can move smoothly on the guide rod, thereby achieving a stable clamping of the coil base. The sliding mechanism allows for even distribution of clamping force, reducing localized pressure concentration and improving clamping stability.

[0024] This utility model provides a spiral inductor coil winding fixture. It has the following beneficial effects:

[0025] The fixture uses a left and a right fixing component to clamp and fix the coil base. The left fixing component fixes one end of the coil base with a first rubber cone, and the right fixing component fixes the other end with a second rubber cone. This double-sided fixing structure ensures the stability of the coil base during the winding process, preventing positional displacement and guaranteeing winding accuracy.

[0026] The left fixing component can move within the slide groove and be secured by a limiting plate, facilitating precise positioning and adjustment for coil bases of different sizes. This design greatly enhances the applicability of the tooling, enabling it to quickly adapt to coil bases of different sizes, reducing adjustment time and improving production efficiency.

[0027] The left fixing component is connected to a cylinder, which is connected to the connecting plate via its output end, enabling automatic clamping and release of the coil base. This automated design reduces the complexity and workload of manual operation, making the process simpler and more efficient, and adaptable to the needs of modern production lines.

[0028] The sliding groove structure on the base allows for appropriate adjustment of the position of the left fixing component, which is then secured by a limiting plate, ensuring stable positioning during operation. This sliding groove limiting design enhances the flexibility of the tooling, allowing for adjustment of the clamping position according to coil bases of different sizes, ensuring optimal fixation for each operation.

[0029] A spring is fitted on the guide rod in the right fixing assembly, providing elastic support for the second rubber cone. When clamping the coil base, the spring automatically adjusts the clamping force according to the specific shape and size of the coil base, ensuring fixation without applying excessive pressure to the coil base. This design reduces the risk of damage to the coil base and is particularly suitable for more precise coil winding.

[0030] The crank and handle on the right fixed assembly are designed for both manual and motor-driven operation, allowing operators to choose the appropriate drive method based on their needs. In manual operation, rotating the handle drives the guide rod and rubber cone to clamp the coil base. For high-efficiency mass production, a motor can be connected for automated drive, further improving work efficiency. The rotation function of the right fixed assembly allows adjustment of the coil base's rotation angle and speed during winding, making the winding process more controllable and precise, and enabling flexible adjustments according to different process requirements.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0041] Example 1: A spiral inductor coil winding fixture includes a base 4 on which a left fixing component 1 and a right fixing component 3 are mounted. The left fixing component 1 and the right fixing component 3 fix the coil base 2. The base 4 has a base plate 404 with a sliding groove 401. The left fixing component 1 is mounted on the base plate 404 through the sliding groove 401. A right side plate 405 is welded to the end of the base plate 404 opposite to the left fixing component 1. A support plate 402 is provided at the bottom of the base 4, and a reinforcing rib 403 is provided at the connection between the base plate 404 and the right side plate 405. The support plate 402 at the bottom of the base 4 provides a larger support surface, thereby reducing the tilting or instability that may be caused by insufficient contact area of ​​the base 4. Especially during the winding process, the equipment may be subjected to lateral forces generated by rotation or external operation. The support plate 402 can effectively disperse these forces, prevent the equipment from tipping over or sliding, and ensure the safety and stability of operation. Meanwhile, the reinforcing rib 403 at the connection between the base plate 404 and the right side plate 405 increases rigidity by increasing the material thickness or complexity in this area. This design effectively prevents bending or deformation at the connection between the base plate 404 and the right side plate 405 under heavy loads or continuous operation, ensuring the stability of the equipment under high loads. The right fixing assembly 3 is installed on the base plate 404 via the right side plate 405.

[0042] Example 2: To flexibly fix the coil base 2, for example, as follows Figures 1 to 4As shown, the present invention further includes: a guide rod 301 provided on the right fixing component 3, a second rubber cone block 302 movably mounted on the guide rod 301, a bushing 304 mounted on the guide rod 301, the right fixing component 3 being rotatably mounted on the right side plate 405 via the bushing 304, a spring 303 mounted between the guide rod 301 and the second rubber cone block 302 and the bushing 304, the spring 303 providing elastic support for the second rubber cone block 302, a crank 305 mounted at the end of the guide rod 301, a handle 306 mounted on the crank 305, the handle 306 being manually operated or driven by a motor, facilitating the crank 305 to be driven by the handle 306, thereby driving the guide rod 301 to rotate, and the coil base 2 clamped and fixed by the first rubber cone block 102 and the second rubber cone block 302 to rotate, thereby winding and coiling the cable through the coil base 2. The design of the handle 306 makes manual operation more comfortable. The crank 305 provides a longer operating lever, which reduces the force required for each operation, lowers the labor intensity of operation, and improves user comfort. The handle 306 design allows for easier operation over extended periods. The mechanical structure of the crank 305 helps distribute the applied force, reducing hand fatigue during operation. The left fixed assembly 1 has a left side plate 101, on which a first rubber cone 102 is rotatably mounted. A limiting plate 105 is located at the bottom of the left side plate 101. The left fixed assembly 1 is secured to the slide groove 401 of the base 4 by the left side plate 101 and the limiting plate 105. A connecting plate 104 is located at the bottom of the limiting plate 105, and the connecting plate 104 is connected and fixed to the output end of the cylinder 103. The limiting plate 105 at the bottom of the left side plate 101 provides precise positioning. The locking of the limiting plate 105 into the slide groove 401 of the base 4 ensures the stability of the left fixed assembly 1 on the fixture, preventing positional shifts during operation. This design ensures that the clamping position of the coil base 2 remains precise at all times, thereby improving the consistency and accuracy of winding. The left fixing component 1 is engaged in the slide groove 401 by the left side plate 101 and the limiting plate 105, allowing the component to slide and adjust along the slide groove 401 as needed. This design allows operators to quickly adjust the position of the left fixing component 1 according to different sizes of coil base 2 or process requirements, improving the adaptability and operational flexibility of the tooling. The connecting plate 104 at the bottom of the limiting plate 105 is fixedly connected to the output end of the cylinder 103, enabling the left fixing component 1 to be automatically clamped by the pushing force of the cylinder 103.The cylinder 103 provides a stable and adjustable clamping force. The clamping force and speed are precisely adjusted by pneumatic control, which is more labor-saving and uniform than manual clamping. It is very suitable for winding operations that require high repeatability and high efficiency. The cylinder 103 is located on the bottom surface of the base plate 404 and between the support plate 402 of the base plate 404. The cylinder 103 is set on the bottom surface of the base plate 404 and between the base plate 404 and the support plate 402, which can effectively protect the cylinder 103 from external mechanical impact or operational interference. The support plate 402 provides additional protection for the cylinder 103, reducing the risk of damage that may occur when the cylinder 103 is exposed to the external environment. The coil base 2 is clamped and fixed by the first rubber cone 102 and the second rubber cone 302. Through holes are provided on the left side plate 101 and the first rubber cone 102, and the size of the through holes is adapted to the size of the guide rod 301. The left side plate 101 and the first rubber cone 102 are slidably mounted on the guide rod 301 to achieve the effect of clamping and fixing the coil base 2 by the first rubber cone 102 and the second rubber cone 302. The size of the through holes matches the diameter of the guide rod 301, so that the left side plate 101 and the first rubber cone 102 can slide smoothly on the guide rod 301. This precise fit ensures that the left side plate 101 and the first rubber cone 102 slide evenly on the guide rod 301, avoiding instability or positional displacement caused by improper fit. Through the sliding installation design of the through hole, the first rubber cone 102 and the left side plate 101 can move smoothly on the guide rod 301, thereby achieving a stable clamping of the coil base 2. This sliding mechanism ensures a uniform distribution of clamping force, reduces local pressure concentration, and improves clamping stability.

[0043] Working principle:

[0044] First, the operator places the coil base 2 in the designated position on the fixture. The left fixing assembly 1 includes a left side plate 101, a first rubber cone 102, a limiting plate 105, and a cylinder 103. One end of the coil base 2 is initially fixed by the first rubber cone 102. The through hole on the left side plate 101 matches the guide rod 301, ensuring that the left side plate 101 can slide along the guide rod 301 to adjust its position. The function of the cylinder 103 is to push the limiting plate 105 and the left side plate 101, bringing the first rubber cone 102 into close contact with the coil base 2, thereby achieving a stable clamping of one end of the coil base 2.

[0045] The right fixing assembly 3 mainly includes a guide rod 301, a second rubber cone 302, a bushing 304, a spring 303, a crank 305, and a handle 306. The guide rod 301 passes through the right side plate 405 and is connected to the right side plate 405 through the bushing 304, allowing the guide rod 301 to rotate within the bushing 304. The second rubber cone 302 slides along the guide rod 301 and contacts the other end of the coil base 2. Under the action of the spring 303, the second rubber cone 302 automatically adjusts the clamping force to ensure that the other end of the coil base 2 is reliably fixed.

[0046] After the coil base 2 is fixed, the winding process is achieved by rotating the coil base 2. The crank 305 and handle 306 in the right fixing assembly 3 are designed to be manually or electrically driven. The operator can manually rotate the handle 306 or drive the crank 305 to rotate by connecting a motor. When the crank 305 rotates, it will drive the second rubber cone 302 and the clamped coil base 2 to rotate together through the guide rod 301. Since the other end of the coil base 2 is clamped and fixed by the first rubber cone 102 of the left fixing assembly 1, the coil base 2 can rotate smoothly around its axis.

[0047] As the coil base 2 rotates, the cable pre-fixed on the winding device will begin to wind around the base. The speed and angle of rotation can be controlled by adjusting the crank 305 or the speed of the motor drive, thereby precisely controlling the winding density and method of the cable.

[0048] During the winding process, the spring 303 of the right fixing component 3 provides continuous elastic support, ensuring that the second rubber cone 302 always clamps the coil base 2 with appropriate pressure. This design prevents damage to the coil base 2 due to excessive clamping force, while ensuring that the base does not loosen during rotation. If it is necessary to adjust the clamping position of the coil base 2 or re-fix it, the operator can make fine adjustments by adjusting the position of the left fixing component 1 in the slide groove 401, ensuring precise positioning for each operation.

[0049] Once the winding process is complete, the operator can release the pressure of cylinder 103 to loosen the left fixing component 1, thereby easily removing the coil base 2. The second rubber cone 302 of the right fixing component 3 will also reset under the action of spring 303, ready for the next base fixing and winding operation.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
