Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a coil winding positioning device. Background Technology

[0002] In the field of coil manufacturing, precise and efficient winding positioning technology is crucial. As a key component in many electrical devices, the winding quality of coils directly affects the performance and stability of the equipment. With the continuous development of the electrical industry, higher demands are being placed on the precision, consistency, and production efficiency of coils. Therefore, developing a winding positioning technology that can reliably fix the coil winding cylinder, achieve synchronous rotation winding, and adapt to different height requirements has significant practical implications.

[0003] Existing coil winding positioning technologies have shortcomings. First, there is a lack of effective and stable fixing devices for the coil winding cylinder, making it prone to displacement during winding. This results in loose and uneven coils, affecting the coil's electrical performance. Second, most technologies struggle to achieve synchronous rotation of multiple winding units. Inconsistent rotation speeds and rhythms between different winding units lead to poor coil consistency, failing to meet the demands of large-scale, standardized production. Utility Model Content

[0004] The purpose of this invention is to provide a coil winding positioning device to solve the problem of poor positioning effect during existing coil winding as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A coil winding positioning device includes a winding worktable for winding coils, a servo lifting hydraulic cylinder is installed at one end of the winding worktable, and a positioning top seat is installed on the top of the piston rod of the servo lifting hydraulic cylinder. The winding workbench has a hollow structure and is equipped with several sets of rotating shafts. Each set of rotating shafts is coaxially connected to a rotating column for coil winding. Each set of rotating columns is equipped with a limiting plate for fixing the coil winding cylinder. Each set of rotating shafts is coaxially equipped with a pulley. One set of pulleys on two adjacent sets of rotating shafts is connected by a transmission belt. The positioning top seat has through holes that are the same number and position as the rotating columns, and the diameter of the through holes is greater than the distance between the diagonals of the cross-section of the rotating columns.

[0006] Preferably, the inner ring of the coil winding cylinder and the cross-section of the rotating column are both square, which can enhance the stability of the connection between the two, make the torque transmission more efficient during rotation, effectively reduce relative slippage, make the coil winding process more stable, and improve the winding accuracy.

[0007] Preferably, the top and bottom surfaces of the winding worktable are both fitted with bearings for fixing the rotating shaft. The bearings can reduce friction when the rotating shaft rotates, provide good support for it, ensure smooth and stable rotation of the rotating shaft, and extend the service life of the rotating shaft and the worktable.

[0008] Preferably, a servo motor is installed at one end of the bottom of the winding worktable to drive one of the sets of rotating shafts to rotate. This provides stable power to the entire winding system and ensures that the rotating shafts rotate according to predetermined requirements. This is the key to achieving automated and efficient winding.

[0009] Preferably, the servo motor is mounted on the bottom surface of the winding worktable via a fixing plate. The fixing plate enhances the servo motor's mounting stability, making it less prone to shaking or displacement during operation and ensuring the stability of power transmission.

[0010] Preferably, a bracket is installed at the bottom of the winding worktable at the end away from the servo lifting hydraulic cylinder, which enhances the overall stability of the device and prevents the worktable from tilting or shaking during the winding process.

[0011] Preferably, the bottom of the bracket and the bottom of the servo lifting hydraulic cylinder are on the same horizontal plane, which ensures the stability of the device and keeps the winding worktable in a horizontal state, which is beneficial to improving the quality and accuracy of coil winding.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: In this coil winding positioning device, the winding worktable provides a stable operating platform for coil winding. A servo lifting hydraulic cylinder installed at one end can precisely control the lifting and lowering of the piston rod. The positioning top seat installed on the top of the piston rod can move up and down with the piston rod, thus adapting to coil winding requirements at different heights. The hollow structure inside the winding worktable facilitates the installation of several sets of rotating shafts. A rotating column coaxially connected to each set of rotating shafts provides rotational support for coil winding. A limiting plate installed on the rotating column effectively fixes the coil winding cylinder, preventing displacement during winding. Pulleys coaxially installed on each set of rotating shafts, as well as one set of pulleys on adjacent sets of rotating shafts, are connected via a transmission belt, achieving synchronous rotation of multiple sets of rotating shafts and improving coil winding efficiency. The positioning top seat has through holes of the same number and corresponding position as the rotating columns, with a diameter larger than the diagonal spacing of the rotating column cross-section. This ensures that the positioning top seat does not interfere with the rotating columns during lifting and lowering, guaranteeing stable operation of the device. Attached Figure Description

[0017] Coil winding positioning device, such as Figures 1-3As shown, the device includes a winding worktable 10 for coil winding. A servo lifting hydraulic cylinder 20 is installed at one end of the winding worktable 10, and a positioning top seat 30 is installed on the top of the piston rod 21 of the servo lifting hydraulic cylinder 20. The winding worktable 10 has a hollow internal structure and is equipped with several sets of rotating shafts 15. Each set of rotating shafts 15 is coaxially connected to a rotating column 12 for coil winding. Each set of rotating columns 12 is equipped with a limiting plate 13 for fixing the coil winding cylinder 50. Each set of rotating shafts 15 is coaxially equipped with a pulley 16. One of the sets of rotating shafts 15 is located on each of the adjacent sets of rotating shafts 15. The pulley 16 is connected via a transmission belt 17. The positioning top seat 30 has through holes 31 in the same number and corresponding positions as the rotating columns 12. The diameter of the through holes 31 is larger than the diagonal spacing of the rotating column 12's cross-section. The winding worktable 10 provides a stable operating platform for coil winding. A servo lifting hydraulic cylinder 20 installed at one end of the worktable can precisely control the lifting and lowering of the piston rod 21. The positioning top seat 30 installed on the top of the piston rod 21 can move up and down with the piston rod 21, thus adapting to coil winding requirements at different heights. The hollow internal structure of the winding worktable 10 facilitates the installation of several sets of rotating shafts 15. Rotating columns 12 coaxially connected to each set of rotating shafts 15 provide rotational support for coil winding. The limiting disc 13 installed on the rotating column 12 effectively fixes the coil winding cylinder 50, preventing displacement during winding. Each set of rotating shafts 15 is coaxially mounted with pulleys 16, and one set of pulleys 16 on two adjacent sets of rotating shafts 15 is connected by a transmission belt 17, realizing the synchronous rotation of multiple sets of rotating shafts 15 and improving coil winding efficiency. The positioning top seat 30 has the same number of through holes 31 as the rotating columns 12 and corresponding in position, and the diameter of the through holes 31 is larger than the diagonal spacing of the cross-section of the rotating columns 12, ensuring that the positioning top seat 30 will not interfere with the rotating columns 12 during the lifting and lowering process, thus ensuring the stable operation of the device.

[0018] It is worth noting that the inner ring of the coil winding cylinder 50 and the cross-section of the rotating column 12 are both square, which allows the coil winding cylinder 50 to be stably fitted onto the rotating column 12. The two fit tightly together and can effectively transmit torque during rotation, ensuring the stability and accuracy of coil winding and reducing the relative sliding between the coil winding cylinder 50 and the rotating column 12 during winding.

[0019] Furthermore, the top and bottom surfaces of the winding worktable 10 are both fitted with bearings 11 for fixing the rotating shaft 15, so that the rotating shaft 15 can be well supported and fixed during rotation, reducing the frictional resistance of the rotating shaft 15 during rotation, ensuring the smoothness of the rotating shaft 15, and also extending the service life of the rotating shaft 15 and the winding worktable 10.

[0020] The bottom end of the winding worktable 10 is equipped with a servo motor 14 that drives one set of rotating shafts 15 to rotate. The servo motor 14 is mounted on the bottom surface of the winding worktable 10 through a fixed plate, so that the servo motor 14 can stably provide power to the rotating shafts 15. The mounting method of the fixed plate ensures the stability of the servo motor 14 during operation, thereby ensuring a stable and reliable power supply for the entire coil winding process.

[0021] In addition, a bracket 40 is installed at the bottom of the winding worktable 10 away from the servo lifting hydraulic cylinder 20. The bottom of the bracket 40 and the bottom of the servo lifting hydraulic cylinder 20 are on the same horizontal plane, so that the whole device can maintain horizontal stability during operation. The bracket 40 and the servo lifting hydraulic cylinder 20 jointly support the winding worktable 10, which enhances the overall stability of the device and avoids affecting the coil winding quality due to device instability.

[0022] The working principle of this coil winding positioning device: First, based on production requirements, a suitable coil winding cylinder 50 is securely installed on the rotating column 12; both the rotating column 12 and the inner ring of the coil winding cylinder 50 have square cross-sections. This design allows the two to fit together tightly, laying the foundation for stable winding in the future. Next, the servo lifting hydraulic cylinder 20 is activated, and its piston rod 21 drives the positioning top seat 30 to descend, so that the positioning top seat 30 accurately positions the top of the coil winding cylinder 50; the positioning top seat 30 is provided with a through hole 31 corresponding to the position of the rotating column 12, and the diameter of the through hole 31 is reasonable to ensure that the descent process is smooth and without interference. After positioning is completed, the servo motor 14, which is mounted on the bottom of the winding worktable 10 via a fixed plate, is started. The servo motor 14 drives one set of rotating shafts 15 to rotate. Through the transmission of pulley 16 and transmission belt 17, multiple sets of rotating shafts 15 rotate synchronously, and the rotating column 12 rotates accordingly to start the winding operation. The bearings 11 embedded on the top and bottom surfaces of the winding worktable 10 ensure the smooth rotation of the rotating shaft 15. At the same time, the winding worktable 10 maintains a stable state under the joint support of the servo lifting hydraulic cylinder 20 and the bracket 40, ensuring the winding quality. After the winding is completed, the servo motor 14 is turned off, the positioning top seat 30 is raised, and the wound coil can be removed.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
