Description

Technical Field

[0001] The present invention relates to the technical field of current transformer processing, and specifically, to a wire winding device for current transformer processing. Background Technique

[0002] A current transformer is an electrical device that transforms a large current into a small current at a certain ratio. It works based on the principle of electromagnetic induction and is mainly used in measuring instruments and protection devices to safely and accurately measure and protect the power system. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series in the circuit where the current to be measured is located;

[0003] Chinese Patent Publication No.: CN117457381A discloses an automatic wire winding device for current transformer coils, including a cylinder body. A centering mechanism for adjusting the position of the current transformer is arranged on the cylinder body. An upper feeding component is arranged above the cylinder body. The upper feeding component and the centering mechanism cooperate to complete the processes of feeding and position adjustment. The centering mechanism includes a limiting cylinder, a first hydraulic cylinder, a pushing component, and a clamping block. A cylindrical hole matching the limiting cylinder is opened at the center of the surface of the cylinder body. The limiting cylinder is slidably connected in the cylindrical hole. The first hydraulic cylinder is installed at the bottom of the cylinder body through an L-shaped seat, and there are two first hydraulic cylinders symmetrically arranged about the cylindrical hole on the left and right. The telescopic end of the first hydraulic cylinder is fixedly connected to the limiting cylinder. Through the cooperation of the above-mentioned components provided in the present invention, the stable rotation of the current transformer is realized, so that the wire winding is more accurate;

[0004] Although the above patent realizes the stable rotation of the current transformer by using a hydraulic cylinder and a limiting cylinder, thus making the wire winding of the current transformer more accurate, it does not consider that during the process of winding the internal magnetic core of the current transformer, most rely on manual operation, which not only has low efficiency but also is difficult to ensure that problems such as wire breakage and uneven winding may occur during the winding process, thus affecting the quality and reliability of the product;

[0005] In view of this, we propose a wire winding device for current transformer processing. Summary of the Invention

The rotating rod 1251 between the second helical gear 126 and the third helical gear 1261 is rotatably connected to the inner wall of the drive chamber 1 through a cross column.

[0038] Figures 3 - 5As shown, the rotating assembly 2 includes a motor 21, a base 23, and support columns 24. The motor 21 is fixedly connected to the top of one side of the base 23, and the two support columns 24 are fixedly connected to the top of the base 23. The output end of the motor 21 is fixedly connected to a first runner 22. The first runner 22 is rotatably connected to the outer wall of the support column 24. A first drive belt 221 is sleeved on the outer wall of the first runner 22. The inner wall of the other side of the first drive belt 221 is provided with a second runner 222. The second runner 222 is sleeved on the outer wall of the first drive belt 221. The second runner 222 is fixedly connected to a drive roller 2221 through a rotating shaft penetrating the upper outer wall of the support column 24. The first runner 22 and the drive roller 2221 are rotatably connected to the lower outer walls of the two support columns 24. The second runner 222 and the drive roller 2221 are rotatably connected to the upper outer walls of the two support columns 24. A third drive belt 224 is sleeved on the outer walls of the two first runners 22 on the outer walls of the two support columns 24. A third drive belt 224 is sleeved on the outer walls of the first runner 22 and the second runner 222 on one side of the support column 24 away from the first drive belt 221. Among them: A second drive belt 223 is sleeved on the outer walls of the first runners 22 at the lower ends of the two support columns 24.

[0039] As Figures 4 - 5 shown, on the side of the two support columns 24 away from the first runner 22, there are rotatably connected stabilizing rollers 241. A winding ring 25 is arranged between the two stabilizing rollers 241. A plurality of second runners 222 are rotatably connected to the outer wall of the winding ring 25. On the side of the winding ring 25 away from the support column 24, there is fixedly connected a wire bundling box 251. A fan-shaped notch is opened on the outer wall of the winding ring 25. A magnetic core 3 is arranged inside the winding ring 25. The magnetic core 3 is rotatably connected to the outer wall of the rotating column 121. At the central position of the drive roller 2221 at the lower end of one side of the support column 24, there is fixedly connected a fourth bevel gear 127. The fourth bevel gear 127 is meshed and connected with a third bevel gear 1261.

[0040] It can be seen from this that when it is necessary to wind the magnetic core 3 inside the current transformer, as Figures 4 - 5As shown, the staff vertically place the magnetic core 3 from the notch position on the outer side of the winding ring 25 between the two support columns 24 and are restricted by the rotating columns 121 on both sides. Then, the staff dial the two limiting columns 123 inward towards the position of the magnetic core 3 and fix the magnetic core 3 with the limiting columns 123. Then, the device is started. Driven by the motor 21, the first runner 22 rotates. At this time, the two first runners 22 and the second runners 222 on both sides are driven by the first transmission belt 221 and the third transmission belt 224 to rotate in the same direction together. The first runners 22 at the lower ends on both sides drive the same-direction rotation below through the second transmission belt 223. At this time, the first runners 22 and the second runners 222 rotate together with the transmission rollers 2221 on the other side of the support column 24. At this time, the transmission rollers 2221 drive the winding ring 25 to rotate. At this time, the wire-releasing box 251 on the winding ring 25 continuously releases wire. At the same time, under the rotation of the winding ring 25, wire is wound around the outer wall of the magnetic core 3. In this way, it only requires the staff to place the magnetic core 3 inside the support column 24 for automatic wire winding;

[0041] In addition, when the motor 21 drives the second runner 222 to rotate, it will drive the fourth helical gear 127 to rotate. At the same time, the fourth helical gear 127 drives the third helical gear 1261 and the second helical gear 126 to rotate. At the same time, the second helical gear 126 will drive the first helical gear 1252 and the second gear 125 to rotate. And the second gear 125 will drive the first gear 124 to rotate. Driven by the first gear 124, the rotating column 121 rotates. At this time, the magnetic core 3 rotates together with the rotation of the rotating column 121. At this time, in cooperation with the rotation of the winding ring 25, wire is wound around the periphery of the magnetic core 3, which can ensure the accuracy of wire winding.
