Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer core winding technology, and in particular to a core winding device. Background Technology
[0002] Instrument transformers are devices used in power systems to transform voltage or current. They are divided into voltage transformers and current transformers, which can convert high voltage and large current into low voltage and small current for easy measurement and protection. Their internal core is made of laminated silicon steel sheets and is the core of the magnetic circuit. Its function is to transfer energy through electromagnetic induction. The high permeability of the silicon steel sheets reduces magnetic losses.
[0003] Iron core winding is used to form primary and secondary coils. When an alternating current is applied to the primary coil, the iron core generates an alternating magnetic field, inducing a corresponding voltage or current in the secondary coil, thus achieving the electromagnetic conversion of electrical energy. The ratio of the number of turns in the winding determines the voltage or current conversion factor. Traditional iron core winding still relies on manual operation, and the winding setup is limited to simple iron core structures. For non-toroidal iron cores, the winding stability is poor, and it is impossible to guarantee uniform rotation of the iron core during winding, thereby reducing winding accuracy.
[0004] Based on this, a core winding device is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a core winding device to solve the above-mentioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A core winding device includes a base, a wheel frame connected to the base, clamping wheels connected to the wheel frame, winding wheels connected between the clamping wheels, a connecting rod connected to the base, a roller rotatably connected to the upper end of the connecting rod, a transmission belt connected to the roller, and a support mechanism connected to one side of the base for supporting the transmission belt to clamp and drive the core.
[0008] Preferably, a mating bar is rotatably connected to the winding wheel.
[0009] Preferably, one end of the docking bar is connected to a limit button via a spring, and the limit button is engaged with one end of the winding wheel.
[0010] Preferably, a limiting plate is connected to the connecting rod, and the roller is positioned above the limiting plate.
[0011] Preferably, the support mechanism includes a motor frame, a slide rod connected to one side of the motor frame, the slide rod being slidably connected to the base, a support spring connected to the slide rod, a rotary motor connected to the motor frame, a rotary cylinder connected to the output end of the rotary motor, and a transmission belt connected to the rotary cylinder.
[0012] Preferably, a connecting frame is connected to one side of the base, and a deflection rod is rotatably connected to the connecting frame.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0014] 1. This application adopts a support spring structure, which uses the support spring in conjunction with the transmission belt to cover and clamp the iron core, and the iron core is pressed against the roller through the transmission belt. As the transmission belt rotates, it drives the iron core to rotate. Since the transmission belt structure can be matched with iron cores of any shape, it improves the applicability of different iron core windings.
[0015] 2. This application adopts a deflection rod structure to limit the conveyor belt and prevent it from contacting the winding wheel. This facilitates the quick assembly of the iron core onto the winding wheel and the transmission belt during the winding of the iron core. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-3 This utility model provides a technical solution:
[0023] A core winding device includes a base 1, a wheel frame 10 connected to the base 1, and a clamping wheel 11 connected to the wheel frame 10. The clamping wheel 11 limits the winding wheel 12. When the clamping wheel 11 rotates, it can synchronously drive the winding wheel 12 to rotate, thereby winding the copper wire on the winding wheel 12 onto the core. The structure of the winding wheel 12 is a direct reference to the prior art. The clamping wheels 11 are connected to the winding wheel 12. A connecting rod 2 is connected to the base 1. A roller 3 is rotatably connected to the upper end of the connecting rod 2. The structure of the roller 3 can complete the contact and limiting of the core, ensuring that the core can rotate at a uniform speed as the copper wire is wound. A transmission belt 9 is connected to the roller 3. A support mechanism is connected to one side of the base 1 to support the transmission belt 9 to clamp and drive the core.
[0024] Specifically, such as Figure 3 As shown, a connecting bar 16 is rotatably connected to the winding wheel 12, which improves the ease of core installation.
[0025] Specifically, such as Figure 3 As shown, one end of the mating bar 16 is connected to a limit button 17 via a spring. The limit button 17 is engaged with one end of the winding wheel 12. One end of the mating bar 16 has a groove in which a spring is connected. The spring pushes the limit button 17 to engage with the winding wheel 12, thereby preventing the mating bar 16 from deflecting and making the mating bar 16 and the winding wheel 12 form a complete circular structure.
[0026] Specifically, such as Figure 3 As shown, a limiting disk 13 is connected to the connecting rod 2, and the roller 3 is set above the limiting disk 13. The limiting disk 13 provides support for the iron core. When the copper wire is wound, the lower surface of the iron core is in contact with the limiting disk 13.
[0027] Specifically, such as Figure 3As shown, the support mechanism includes a motor frame 4, with a slide rod 5 connected to one side of the motor frame 4. The slide rod 5 has two components to prevent the motor frame 4 from rotating and to improve the stability of the horizontal movement of the motor frame 4. The slide rod 5 is slidably connected to the base 1, and a support spring 6 is connected to the slide rod 5. A rotary motor 7 is connected to the motor frame 4, and a rotary cylinder 8 is connected to the output end of the rotary motor 7. A transmission belt 9 is connected to the rotary cylinder 8. After the rotary motor 7 is started, it can drive the rotary cylinder 8 to rotate, thereby cooperating with the transmission belt 9 to pull the iron core to rotate, which facilitates the winding of copper wire onto the iron core.
[0028] Specifically, such as Figure 3 As shown, a connecting frame 14 is connected to one side of the base 1, and a deflection rod 15 is rotatably connected to the connecting frame 14. By setting the deflection rod 15, the transmission belt 9 can be fastened to the deflection rod 15 when the device is not running, thereby preventing the transmission belt 9 from abutting against the winding wheel 12. At this time, it is convenient for the operator to install the iron core on the winding wheel 12. The support spring 6 can pull the motor frame 4 to move towards the base 1.
[0029] In summary, the iron core winding device provided in this embodiment allows for the deflection of the mating bar 16 by pressing the limit button 17 when winding the iron core of a current transformer. The iron core is then placed on the winding wheel 12, and the transmission belt 9 is pulled to bring it against the outside of the iron core, ensuring that one side of the iron core is in contact with the transmission belt 9 on the outside of the drum 3. The rotary motor 7 is then started, driving the rotary drum 8 to rotate, thereby pulling the transmission belt 9. At this time, the iron core is clamped between the transmission belt 9 and the drum 3. The winding wheel 12 is then started to wind the copper wire around the outside of the iron core, thus completing the iron core winding operation.
[0030] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
