Description

Technical Field

[0001] This utility model relates to the technical field of winding devices, specifically a winding device for transformer cores. Background Technology

[0002] The transformer core is the main magnetic circuit part of the transformer. It is usually made of hot-rolled or cold-rolled silicon steel sheets with high silicon content and coated with insulating varnish. The transformer core and the coil wound on the core form a complete electromagnetic induction system. During the processing of the transformer core copper wire, a winding device is needed to wind the copper wire.

[0003] A search revealed Chinese Patent CN212230244U, which discloses a transformer core winding device, including a three-jaw chuck, a first support rod, and a rotating tube. The first support rod is positioned above the three-jaw chuck. This invention, by using a three-jaw chuck, first support rod, second support rod, third support rod, and fastening screws, can securely tighten transformers of different specifications.

[0004] While the above-mentioned solutions can fix transformers of different specifications, the copper wire cannot move back and forth on the threaded groove during the winding process, resulting in the copper wire not being evenly wound on the iron core. This can easily lead to coiling and knotting, causing the transformer to malfunction. To address this issue, we provide a transformer iron core winding device. Utility Model Content

[0005] The purpose of this invention is to provide a winding device for transformer cores to solve the problems mentioned in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding device for a transformer core, comprising a fixed base plate, a winding mechanism for wire pulling is provided above the fixed base plate, the winding mechanism comprising a driving gear, two driven gears meshing with the outer surface of the driving gear, a connecting rotating rod fixedly connected to the inner wall of each driven gear, a driven sector gear fixedly connected to one end of the connecting rotating rod, a reciprocating toothed plate meshing with the outer surface of the driven sector gear, a fixing mechanism being provided above the fixed base plate, the fixing mechanism comprising a clamping frame, a rotating shaft rotatably connected to the outer surface of the clamping frame.

[0007] Preferably, a limiting sliding block is fixedly connected to the top surface of the reciprocating toothed plate, and a toggle rod is fixedly connected to the top surface of the limiting sliding block. By moving the toggle rod horizontally back and forth, the copper wire can be driven to swing back and forth simultaneously.

The slider slides into the inner wall of the fixed base plate, thereby making the protective box more stable when it moves.

[0009] Preferably, a drive motor is fixedly connected to the inner bottom wall of the protective box, and the output end of the drive motor is fixedly connected to the drive gear. By turning on the drive motor, the drive gear can be effectively driven to rotate.

[0010] Preferably, an electric actuator is fixedly connected to the inner wall of the fixed base plate, the telescopic end of the electric actuator is fixedly connected to the protective box, and a control button for the electric actuator is installed on the outer surface of the fixed base plate.

[0011] Preferably, a first limiting slide rod is fixedly connected to the inner wall of the fixed base plate, and the outer surface of the first limiting slide rod is slidably connected to the protective box. The fixed base plate effectively supports and fixes the first limiting slide rod.

[0012] Preferably, a support plate is fixedly connected to the top surface of the fixed base plate, and a bidirectional threaded rod is rotatably connected to the inner wall of the support plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, through the coordinated arrangement of components in the winding mechanism, enables the drive lever to move the copper wire back and forth horizontally, effectively winding the copper wire evenly onto the transformer core held between the two clamping frames. This avoids the situation where the copper wire is only wound at one position on the surface of the transformer core, causing the copper wire to accumulate and knot, resulting in the transformer being unable to function properly. This further improves the winding quality of this device.

[0016] 2. This application achieves the driving of the bidirectional threaded rod to rotate and drive the two clamping frames to move closer to each other through the coordinated arrangement of the components in the fixing mechanism. This can effectively clamp and limit the transformer cores of different specifications, greatly improve the winding efficiency, and further make the device more stable. Attached Figure Description

[0022] 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.

[0023] like Figure 1 As shown, this utility model provides a technical solution for a winding device for a transformer core, including a fixed base plate 1. A power supply is installed on the outer surface of the fixed base plate 1, which can supply power to the electrical equipment in this application.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a winding mechanism 2 for pulling wire is provided above the fixed base plate 1. The winding mechanism 2 includes a drive gear 201, and two driven gears 202 are meshed on the outer surface of the drive gear 201. By driving the drive gear 201 to rotate, the two driven gears 202 can be driven to rotate in the same direction at the same time.

[0025] Each driven gear 202 has a connecting rotating rod 203 fixedly connected to its inner wall. One end of the connecting rotating rod 203 is fixedly connected to a driven sector gear 204. The outer surface of the driven sector gear 204 is meshed with a reciprocating toothed plate 205. By driving the two driven gears 202 to rotate, the two driven sector gears 204 can be effectively made to rotate simultaneously, driving the reciprocating toothed plate 205 to perform horizontal reciprocating motion.

[0026] A limiting sliding block 206 is fixedly connected to the top surface of the reciprocating toothed plate 205. A toggle rod 207 is fixedly connected to the top surface of the limiting sliding block 206. The outer surface of the limiting sliding block 206 slides in the inner wall of the protective box 208, effectively supporting and limiting the limiting sliding block 206, making the reciprocating toothed plate 205 more stable during movement. A wiping cotton is fixedly installed in the inner wall of the toggle rod 207. The wiping cotton can wipe the surface of the copper wire it passes through, making the copper wire cleaner and tidier.

[0027] A protective box 208 is slidably connected to the top surface of the fixed base plate 1. The inner wall of the protective box 208 is slidably connected to the limiting sliding block 206. The end of the connecting rotating rod 203 away from the driven sector gear 204 is rotatably connected to the protective box 208. By setting the protective box 208, the components in the winding mechanism 2 can be effectively protected, and the external dust is prevented from entering the components and affecting their normal operation.

[0028] A drive motor 209 is fixedly connected to the inner bottom wall of the protective box 208. The output end of the drive motor 209 is fixedly connected to the drive gear 201. The drive motor 209 is electrically connected to the power supply on the surface of the fixed base plate 1 through wires. The outer surface of the fixed base plate 1 is equipped with a control button for the drive motor 209. The control button can effectively start and stop the drive motor 209 and adjust the speed of the output end of the drive motor 209.

[0029] An electric push rod 210 is fixedly connected to the inner wall of the fixed base plate 1. The telescopic end of the electric push rod 210 is fixedly connected to the protective box 208. By turning on the power, the electric push rod 210 is operated to extend and retract, thereby pushing the protective box 208 to move on the top surface of the fixed base plate 1. The protective box 208 drives the actuating rod 207 to move, which can effectively adjust the amplitude of the copper wire swing, so that the winding mechanism 2 can be used for transformers of different specifications.

[0030] The inner wall of the fixed base plate 1 is fixedly connected to a first limiting slide rod 211. The outer surface of the first limiting slide rod 211 is slidably connected to the protective box 208. The setting of the first limiting slide rod 211 effectively limits the protective box 208, making the protective box 208 more stable when moving.

[0031] like Figure 1 and Figure 4 As shown, a fixing mechanism 3 is provided above the fixing base plate 1. The fixing mechanism 3 includes a clamping frame 301. A rotating shaft 302 is rotatably connected to the outer surface of the clamping frame 301. A driving device is installed inside the clamping frame 301. The output end of the driving device is fixedly connected to the rotating shaft 302. An anti-slip pad is fixedly installed on the side of the rotating shaft 302 that is in close contact with the transformer. The anti-slip pad makes the rotating shaft 302 more secure when driving the transformer to rotate.

[0032] A support plate 303 is fixedly connected to the top surface of the fixed base plate 1. A bidirectional threaded rod 304 is rotatably connected to the inner wall of the support plate 303. The outer surface of the bidirectional threaded rod 304 is threadedly connected to the clamping frame 301. By driving the bidirectional threaded rod 304 to rotate, the two clamping frames 301 can be effectively driven to move closer to each other to clamp and fix the transformer.

[0033] The inner wall of the clamping frame 301 is slidably connected with a second limiting slide rod 305. The two ends of the second limiting slide rod 305 are fixedly connected to the support plate 303. By setting the second limiting slide rod 305, the clamping frame 301 is effectively limited and supported, making the clamping frame 301 more stable when moving.

[0034] The drive motor 209, electric actuator 210, and the drive device mentioned in this application are all common electrical devices in the prior art. This application will not elaborate on their models and internal structures, and they can also be replaced by other power sources.

[0035] Working principle: First, the drive device inside the support plate 303 is activated to drive the bidirectional threaded rod 304 to rotate. The rotation of the bidirectional threaded rod 304 causes the two clamping frames 301 to move closer together, so that the surface of the rotating shaft 302 is pressed tightly against the transformer, effectively clamping and fixing the transformer. Next, one end of the copper wire is passed through the actuating rod 207 and fixed to the transformer core. Then, the drive device inside the clamping frame 301 is activated to drive the rotating shaft 302 to rotate the transformer for winding. At the same time, the drive motor 209 is activated to drive the drive gear 201 to rotate. The rotation of the drive gear 201 drives the two driven gears 202 to rotate simultaneously. The driven sector gears 204 at one end of the two connecting rotating rods 203 rotate simultaneously in the same direction. The rotation of the two driven sector gears 204 drives the limiting sliding block 206 on the top surface of the reciprocating tooth plate 205 to slide back and forth in the inner wall of the protective box 208, causing the actuating rod 207 to drive the copper wire to swing back and forth simultaneously. This effectively makes the copper wire evenly wound on the surface core of the rotating transformer, greatly improving the winding efficiency and avoiding the situation where the copper wire is only wound in one position on the surface of the transformer core, causing the copper wire to accumulate and knot, which would prevent the transformer from working properly. This further improves the winding quality of this device.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
