Description
Technical Field
[0001] This utility model relates to the field of transformer production equipment technology, and in particular to a transformer winding device. Background Technology
[0002] As a key piece of equipment in the power equipment manufacturing industry, the transformer winding device's main function is to tightly wind conductors onto the transformer core according to a specific number of turns, layers, and winding method, thereby forming a winding with specific electromagnetic induction characteristics. This device is widely used in the production and manufacturing process of various power transformers and electronic transformers, playing a decisive role in the transformer's performance, quality, and production efficiency. Its operational stability and winding accuracy directly affect the transformer's working efficiency in power transmission, distribution, and electronic equipment.
[0003] Early transformer winding devices had relatively simple structures, mainly consisting of a winding shaft, a conductor conveying mechanism, and a simple clamping device. When faced with transformer cores or windings of different sizes, these early devices lacked effective adjustment mechanisms, making them unable to flexibly adapt to various specifications. This often resulted in unstable clamping or even complete failure to secure the winding, severely impacting the smooth progress of the winding process. With continuous technological advancements, existing winding devices have undergone numerous improvements in their clamping structures, employing partially adjustable clamping components. Screw adjustments have improved adaptability to different sizes to some extent. However, existing winding devices still have significant limitations in size adaptation. While adjusting screws avoids situations where specific-sized cores cannot be clamped, the adjustment process relies on manual operation with a limited range. For cores with large size differences, adjustments often require considerable time. Furthermore, due to the mechanical limitations of existing adjustment structures, stable clamping of certain special ultra-large or ultra-small cores may be impossible, significantly reducing production efficiency and hindering the efficient production of diversified products.

[0031] 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.
[0032] Reference Figure 2 , Figure 3 and Figure 6This utility model provides an embodiment of a transformer winding device, including an operating table 1. A servo motor 3 is fixedly connected to the left side of the outer wall of the operating table 1. The output end of the servo motor 3 passes through the operating table 1 and is fixedly connected to a rotating cylinder 4. The iron core to be wound passes through the right side of the rotating cylinder 4 and is then placed in the middle of the rotating cylinder 4. A rotating column 5 is rotatably connected to the middle of the left side of the inner wall of the rotating cylinder 4. A bidirectional threaded groove 6 is formed in the middle of the outer wall of the rotating column 5. Moving rings 7 are slidably connected to both the left and right sides of the outer wall of the rotating column 5. The inner wall of the moving rings 7 is slidably connected to the inner wall of the bidirectional threaded groove 6. Rotating the rotating rings 10 causes the rotating column 5 to rotate. The rotating cylinder 4 is activated by utilizing the bidirectional threaded groove 6 on the outer side, which allows the moving rings 7 at both ends to move relative to each other. Multiple rotating bars 8 are rotatably connected to the outer wall of the moving rings 7. An arc-shaped plate 9 is rotatably connected to the adjacent side of each of the left and right rotating bars 8. The outer wall of the arc-shaped plate 9 penetrates the inner wall of the rotating cylinder 4. The rotating bars 8 rotate, simultaneously pushing the arc-shaped plate 9 outwards until it contacts the inner wall of the iron core to be wound. A rotating ring 10 is fixedly connected to the right end of the rotating column 5. A limit block 11 is fixedly connected to the outer wall of the rotating ring 10. A limit post 12 is provided on the right side of the limit block 11, and the left side of the limit post 12 penetrates the limit block 11 and is fixedly connected to it. There is an arc-shaped locking block 13, and a limiting bolt 14 is threadedly connected to the top of the inner wall of the limiting block 11. A moving component is provided on the rear side of the operating table 1, and a buffer mechanism 2 is provided on the outer wall of the moving ring 7. Multiple slots 15 are opened on the right side of the rotating cylinder 4, and the inner wall of the slot 15 engages with the outer wall of the limiting bolt 14. The moving component includes an electric telescopic rod 16, the outer wall of which is fixedly connected to the rear side of the operating table 1. A support block 17 is fixedly connected to one end of the electric telescopic rod 16, and the outer wall of the support block 17 is slidably connected to the inner wall of the operating table 1. Rotating the limiting bolt 14 prevents it from pressing against the fixed limiting post 12, and pushes the limiting post 12 to move the arc-shaped locking block. 13 is pressed against the rotating cylinder 4, and then the limiting bolt 14 is rotated again to press and fix the adjusted position, so that the arc plate 9 is fixed in the position after being clamped in the iron core, preventing loosening during the winding process. The inner wall of the support block 17 is rotatably connected to the front and rear sides of the rotating column 18, and the inner wall of the support block 17 is rotatably connected to the left and right sides of the supporting block 17. The copper wire to be wound is passed through the rotating column 18 and the auxiliary column 19 and wound on the iron core. Then the servo motor 3 is started, which drives the rotating cylinder 4 and the clamped iron core to rotate. Under the push of the electric telescopic rod 16, the copper wire is evenly wound on the iron core.
[0033] Specifically, the iron core to be wound is passed through the right side of the rotating cylinder 4 and then placed in the middle of the rotating cylinder 4. At this time, the rotating ring 10 is rotated, causing the rotating column 5 to rotate. Using the outer bidirectional threaded groove 6, the moving rings 7 at both ends of the outer side move relative to each other. During this relative movement, the rotating bar 8 rotates, pushing the arc plate 9 to move outward until the arc plate 9 contacts the inner wall of the iron core to be wound. Then, the limiting bolt 14 is rotated so that it no longer presses against the fixed limiting post 12, pushing the limiting post 12 to release the arc-shaped locking block. 13 is pressed against the rotating cylinder 4, and then the limiting bolt 14 is rotated again to press and fix the adjusted position, so that the arc plate 9 is fixed in the position after being clamped on the iron core, preventing loosening during the winding process. Then, the copper wire to be wound is passed through the rotating column 18 and the auxiliary column 19 and wound on the iron core. Then, the servo motor 3 is started, which drives the rotating cylinder 4 and the clamped iron core to rotate. Under the push of the electric telescopic rod 16, the copper wire is evenly wound on the iron core, thus completing the fixed installation of iron cores of different sizes.
[0034] Reference Figure 3 , Figure 4 and Figure 5 The buffer mechanism 2 includes multiple fixed bars 201. The outer walls of the multiple fixed bars 201 are fixedly connected to the outer wall of the moving ring 7. The outer wall of the fixed bar 201 is slidably connected to a sliding block 202. The outer wall of the sliding block 202 is rotatably connected to the inner wall of the rotating bar 8. The outer side of the sliding block 202 is fixedly connected to a limiting rod 203. The outer wall of the limiting rod 203 is slidably connected to an adjusting block 205. The inner wall of the adjusting block 205 is slidably connected to the outer wall of the fixed bar 201. By rotating the positioning bolt 206, the position of the adjusting block 205 above the fixed bar 201 can be released or clamped. Then, according to the square iron core of different sizes, the preload of the telescopic spring 204 can be adjusted. The outer wall of the adjusting block 205 is fixedly connected to the telescopic spring 204. The blocked arc plate 9 will drive the sliding block 202 to slide above the fixed bar 201 and squeeze the telescopic spring 204. One end of the telescopic spring 204 is fixedly connected to the outer wall of the sliding block 202. The inner wall of the adjusting block 205 is threadedly connected to the positioning bolt 206.
[0035] Specifically, when winding a square iron core, after the arc-shaped plates 9 on the upper and lower or front and rear sides come into contact with the inner wall of the square iron core, the arc-shaped plates 9 are blocked by the square iron core and cannot move. At this time, the continued movement of the moving ring 7 will cause the unblocked arc-shaped plates 9 to move. The blocked arc-shaped plates 9 will drive the sliding block 202 to slide above the fixing bar 201 and squeeze the telescopic spring 204. This will buffer the clamping and fixing of the square iron core. Furthermore, by rotating the positioning bolt 206, the position of the adjusting block 205 above the fixing bar 201 can be released or tightened. Thus, the preload of the telescopic spring 204 can be adjusted according to the different sizes of square iron cores, so that the winding device can wind the square iron core.
[0036] Reference Figure 1 and Figure 2 A column 20 is fixedly connected to the top of the control panel 1. The column 20 can stably raise the warning light 21 to a certain height, so that the signal emitted by the warning light 21 can be clearly seen over a large area. The warning light 21 is fixedly connected to the top of the column 20, and the warning light 21 can visually indicate to the operator and surrounding personnel that the equipment may be malfunctioning. A cabinet door 22 is rotatably connected to the bottom front side of the control panel 1. The cabinet door 22 can effectively prevent external dust and debris from entering the control panel 1. A handle 24 is fixedly connected to the right front side of the cabinet door 22. The handle 24 can... The cabinet door 22 is designed for easy gripping and force application by operators. A ventilation panel 23 is fixedly connected to the inner wall of the cabinet door 22, allowing cold air to enter while expelling hot air from the interior. An outer frame 25 is fixedly connected to the outer wall of the ventilation panel 23, reinforcing and protecting it. A controller 26 is fixedly connected to the left side of the inner wall of the operating table 1. The controller 26 is electrically connected to the servo motor 3 and the electric telescopic rod 16, respectively, and can control the starting and running power of the servo motor 3 and the electric telescopic rod 16.
[0037] Specifically, the support column 20 can stably raise the warning light 21 to a certain height, making the signal emitted by the warning light 21 clearly visible over a wide area. The warning light 21 can visually alert operators and surrounding personnel to potential equipment malfunctions, dangerous operations, or situations requiring special attention, thereby raising awareness and preventing accidents. The cabinet door 22 effectively prevents external dust and debris from entering the operating table 1, protecting the internal electrical components and wiring. The handle 24 allows operators to easily grip and apply force, thus smoothly opening or closing the cabinet door 2. 2. It greatly improves the convenience of operation. The ventilation plate 23 allows cold air from the outside to enter while expelling hot air from the inside, achieving the effect of heat dissipation and cooling. This ensures that the electrical components inside the operating table 1 work in a suitable temperature environment, avoiding performance impact or even damage due to overheating. The outer frame 25 reinforces and protects the ventilation plate 23, preventing it from being deformed or damaged by external forces such as collisions or squeezing during daily use. This ensures that the ventilation plate 23 can continuously and stably perform its ventilation and heat dissipation function. The controller 26 can control the starting and running power between the servo motor 3 and the electric telescopic rod 16 respectively.
[0038] Working principle: First, the iron core to be wound is passed through the right side of the rotating cylinder 4 and placed in the middle of the rotating cylinder 4. Then, the rotating ring 10 is rotated, driving the rotating column 5 to rotate. The outer bidirectional threaded groove 6 causes the moving rings 7 at both ends of the outer side to move relative to each other. During the relative movement of the moving rings 7, the rotating bar 8 also rotates and pushes the arc plate 9 to move outward until the arc plate 9 contacts the inner wall of the iron core to be wound. Then, the limiting bolt 14 is rotated to prevent it from continuing to squeeze the fixed limiting column 12 and push the limiting column 12. The arc-shaped clamping block 13 is pressed tightly against the rotating cylinder 4. Then, the limiting bolt 14 is rotated again to fix the adjusted position, ensuring that the position of the arc-shaped plate 9 is stable after clamping the iron core, preventing loosening during the winding process. Next, the copper wire to be wound is passed through the rotating column 18 and the auxiliary column 19 and wound around the iron core. Finally, the servo motor 3 is started to drive the rotating cylinder 4 and the clamped iron core to rotate. Under the push of the electric telescopic rod 16, the copper wire is evenly wound around the iron core, thereby realizing the fixed installation of iron cores of different sizes.
[0039] Furthermore, through the buffer mechanism 2, when the square iron core is wound, after the arc plate 9 on the upper and lower sides or front and rear sides comes into contact with the inner wall of the iron core, the arc plate 9 cannot move due to the blocking effect of the iron core. At this time, if the moving ring 7 continues to move, the unblocked arc plate 9 will move accordingly, while the blocked arc plate 9 will push the sliding block 202 to slide on the fixed bar 201 and apply pressure to the telescopic spring 204, thereby achieving pressure buffering for clamping and fixing the iron core. By rotating the positioning bolt 206, the position of the adjusting block 205 on the fixed bar 201 can be adjusted to adapt to square iron cores of different sizes. In this way, the preload of the telescopic spring 204 can be adjusted to ensure that the winding device can be used for winding operations of square iron cores of different sizes.
