Description

Technical Field

[0001] This invention relates to the field of transformer coil manufacturing, and more particularly to an adjustable support device for winding transformer coils. Background Technology

[0002] Transformers are core components in power transmission and distribution systems and electrical equipment control systems, while coils are the key components for electromagnetic conversion in transformers. The winding quality of the coils directly determines the transformer's performance, operational stability, and service life. In the industrial production of transformer coils, the electromagnetic conductor must be wound evenly and tightly around the outside of the transformer's take-up reel.

[0003] Currently, the industry commonly uses fixed, dedicated winding molds for clamping and positioning during the winding support of transformer take-up reels. However, due to the wide variety of transformer specifications and models, the sizes of the compatible take-up reels vary significantly, especially the diameter of the hollow portion. Different capacities and operating conditions require different hollow portion sizes of take-up reels. To meet the winding needs of take-up reels with different hollow sizes, existing production processes require the pre-stocking of winding molds of various sizes. When changing to different take-up reels for coil winding, the machine must be stopped, the original winding mold disassembled, and a new, matching winding mold installed before the take-up reel can be clamped, fixed, and subsequent winding operations can proceed.

[0004] Therefore, developing an adjustable support device for transformer coil winding that can be adapted to take-up reels of different hollow sizes and does not require frequent mold changes is a technical problem that urgently needs to be solved by those skilled in the art.

[0010] More preferably, it also includes a guide rod, which is slidably connected to the bottom of the fixed frame. A third spring connects the guide rod and the fixed frame.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] An adjustable support device for winding transformer coils, such as... Figures 1-3As shown, the system includes a base 1, a first rotating shaft 2 rotatably connected to the upper rear of the base 1, a first motor 3 fixedly connected to the right rear side of the base 1, the first motor 3 connected to the first rotating shaft 2, a pay-off reel 4 mounted on the first rotating shaft 2, a twisted shaft 5 rotatably connected to the middle of the base 1, a pull block 501 threadedly connected to the twisted shaft 5, and a sliding connection between the pull block 501 and the base 1, first belt assemblies 6 on both the left and right sides between the first rotating shaft 2 and the twisted shaft 5, a winding rod 7 fixedly connected to the upper part of the base 1, allowing the wire on the pay-off reel 4 to pass through the pull block 501 and around the winding rod 7, a rotating shaft 9 movably connected to both the left and right sides of the front of the base 1, a second belt assembly 10 between the rotating shaft 9 and the twisted shaft 5, and a sliding connection between the second belt assemblies 10 and the rotating shaft 9, a retaining plate 11 fixedly connected to the inner side of each rotating shaft 9, and four spreading plates 12 slidably connected along the circumferential direction to the inner side of each rotating shaft 9, the spreading plates 12 being used to clamp the take-up reel 8. Two first springs 15 are connected between the support plate 12 and the rotating shaft 9. The rotating shaft 9 is provided with a pushing mechanism for pushing the support plate 12 open. The base 1 is provided with a driving mechanism for driving the rotating shaft 9 to move. The pushing mechanism includes a pusher 13, which is slidably connected inside the rotating shaft 9. A return spring 131 is connected between the outside of the pusher 13 and the rotating shaft 9. The return spring 131 is wound around the outside of the pusher 13. A swing rod 14 is rotatably connected between the support plate 12 and the pusher 13. The driving mechanism includes a bidirectional threaded rod 16, which is rotatably connected to the middle of the base 1. A second motor 17 is provided on the right side of the base 1. The output shaft of the second motor 17 is connected to the bidirectional threaded rod 16. Pulling members 18 are slidably connected to the left and right sides inside the base 1. Pulling members 18 are threadedly connected to the bidirectional threaded rod 16. The front part of the pulling member 18 is sleeved on the rotating shaft 9. The front part of the pulling member 18 and the pusher 13 are pressed together.

[0030] When using the adjustable support device for winding the transformer coil, first place the take-up reel 8 between the rotating shafts 9, then turn on the second motor 17. The second motor 17 drives the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 drives the pulling member 18 to move inward. The inward movement of the pulling member 18 pulls the pushing member 13 to move inward. The pushing member 13, through the return spring 131, drives the rotating shaft 9 and the spreading plate 12 to move inward. The take-up reel 8 is placed between the rotating shafts 9 beforehand. The rotating shaft 9 drives the abutment plate 11 to move inward and abut against both ends of the take-up reel 8. The abutment plate 11 then stops moving. At this time, the spreading plate 12 is placed inside the take-up reel 8. Then, the pulling member 18 continues to move inward. At this time, the rotating shaft 9 and the abutment plate 11 stop moving, and the return spring 131 is compressed. At this time, the pushing member 13 pushes the swing rod 14, causing the spreading plate 12 to automatically move outward and spread open, securing the inside of the take-up reel 8. Once the first spring 15 is compressed, the spreader plate 12 can fix the take-up reel 8. Then, the second motor 17 is turned off, and the first motor 3 can be turned on, causing the unwind reel 4 to rotate and loosen the line. At the same time, the first belt assembly 6 drives the twisted shaft 5 to rotate, which in turn drives the pull block 501 to move left and right, gradually moving the line left and right so that the take-up reel 8 can take it in. While the twisted shaft 5 is rotating, the second belt assembly 10 drives the rotating shaft 9 to rotate, which in turn drives the take-up reel 8 to rotate through the spreader plate 12 to wind up the line. After the line is taken in, the first motor 3 is turned off, and then the output shaft of the second motor 17 is reversed, which drives the bidirectional threaded rod 16 to reverse. The bidirectional threaded rod 16 reverses, which drives the pull member 18 to move outward. The pull member 18 drives the rotating shaft 9 to move outward. Under the action of the first spring 15, the spreader plate 12 moves to reset, and the reset spring 131 drives the push member 13 to reset.

[0031] like Figures 3-4 As shown, it also includes a fixed frame 19, which is fixedly connected to the upper right part of the base 1. The bottom of the fixed frame 19 is rotatably connected to a rotating component 20. The rotating component 20 is slidably connected to four lifting components 21 along the circumferential direction. The bottom of each lifting component 21 is slidably connected to two clamping blocks 22. The lower part of each lifting component 21 is rotatably connected to a rotating rod 221. Twisted threads are provided on both sides of the rotating rod 221. The rotating rod 221 is threadedly connected to the clamping blocks 22 through the twisted threads. The second spring 23 is connected between the upper part of the lifting component 21 and the rotating component 20. The lower part of each lifting component 21 is fixedly connected to a column 24. The top of the right-side pulling component 18 is fixedly connected to a wedge-shaped frame 25. The wedge-shaped frame 25 and the column 24 are pressed together.

[0032] like Figure 1 and Figure 5As shown, the right-side abutment plate 11 has multiple equally spaced slots 251 along the circumferential direction. The right side of the right-side abutment plate 11 has a threaded groove 252. The right-side abutment plate 11 is threadedly connected to a bending plate 256 through the threaded groove 252. The bending plate 256 also has multiple slots 251. The slots 251 on the right-side abutment plate 11 and the bending plate 256 are symmetrically arranged. The left side of the bending plate 256 is rotatably connected to a rotating ring 253. The rotating ring 253 and the right-side abutment plate 11 are slidably connected. Four elastic elements 254 are connected between the rotating ring 253 and the right-side abutment plate 11. The right-side pusher 13 has a push rod 255 fixedly connected to both the upper and lower sides of the left side. The push rod 255 and the bending plate 256 are in a pressing fit.

[0033] Before each winding, the end of the line needs to be knotted on the side of the take-up reel 8 to facilitate subsequent winding. However, manual operation is very troublesome each time. Therefore, this embodiment adopts the following solution:

[0034] The end of the wire is placed between the clamping blocks 22 on the front side. Rotating the rotating rod 221 causes the twisted thread to move the clamping blocks 22 inwards, clamping the end of the wire. Then, when the pulling member 18 moves inwards, it causes the wedge frame 25 to move inwards. When the wedge frame 25 contacts the front column 24, it causes the column 24 to move downwards. The column 24 causes the lifting member 21 and the clamping blocks 22 to move downwards, compressing the second spring 23. The clamping blocks 22 then cause the end of the wire to move downwards, causing the wire to be inserted into the groove on the upper right side of the take-up reel 8, the slot 251 on the right side abutting the top of the reel 11, and the slot 251 on the top of the bending reel 256. At this time, the clamping blocks 22 maintain the state of pressing the wire down. As the pushing member 13 continues to move inwards, it causes the pushing rod 255 to move inwards. At this time, the straight surface at the bottom of the wedge frame 25 remains against the column 24, and the pushing rod 255 contacts the bending reel 256. Moving the bending disc 256 to the left causes the rotating ring 253 to move to the left, compressing the elastic element 254. Under the action of the threaded groove 252, the bending disc 256 rotates 15°, bending the end of the wire. This makes it easier for the end of the wire to come off the slot 251 when it is wound later. Then, the rotating rod 221 is reversed, causing the clamping block 22 to release the wire. After the winding is completed, the pulling member 18 is moved outward by the second motor 17, causing the top rod 255 to release the bending disc 256. Under the action of the elastic element 254, the bending disc 256 and the rotating ring 253 move to the right to reset. At the same time, the bending disc 256 reverses to reset. The wedge frame 25 moves to the right to release the column 24. Under the action of the second spring 23, the lifting member 21, the column 24, and the clamping block 22 move upward to reset.

[0035] like Figure 3 and Figure 6 As shown, it also includes a guide rod 26, which is slidably connected to the bottom of the fixed frame 19. A third spring 27 is connected between the guide rod 26 and the fixed frame 19. A pressing rod is fixedly connected to the top of the guide rod 26. Four wedge-shaped annular blocks 29 are fixedly connected to the inner side of the rotating part 20. The wedge-shaped annular blocks 29 and the pressing column 28 are pressed together.

[0036] like Figure 3 and Figure 6 As shown, it also includes a one-way gear disk 30, which is fixedly connected to the outside of the rotating member 20. The one-way gear disk 30 meshes with a first rack 31, which is fixedly connected to the front of the pull member 18 on the right side. Four equally spaced elastic locking pins 32 are fixedly connected to the upper part of the rotating member 20 along the circumferential direction. The fixing frame 19 has locking holes near the elastic locking pins 32, and the locking holes and elastic locking pins 32 are engaged.

[0037] like Figure 6 and Figure 7 As shown, it also includes a track frame 33, which is fixedly connected to the bottom of the fixed frame 19. The track frame 33 is provided with an inclined rail and a vertical groove. A rack frame 35 is slidably connected to the fixed frame 19. A cutter 34 is slidably connected to the bottom of the rack frame 35. The cutter 34 and the track frame 33 are slidably connected. A third motor 37 is provided at the top of the fixed frame 19. The output shaft of the third motor 37 is connected to a first gear 36. The first gear 36 meshes with the rack frame 35.

[0038] like Figure 3 , Figure 6 and Figure 9 As shown, it also includes a second rack 38, the second rack 38 is fixedly connected to the rear of the rack frame 35, and a one-way gear 381 is fixedly connected to the side of the rotating rod 221 near the second rack 38. The one-way gear 381 meshes with the second rack 38. A stop plate 40 is slidably connected to the base 1, and a fourth rack 41 is fixedly connected to the top of the stop plate 40. The fourth rack 41 meshes with the first gear 36.

[0039] When inserting the wire into the slot 251, it needs to be inserted horizontally. Inserting it vertically will prevent it from fitting into the slot 251. Therefore, a guide rod 26 is provided, allowing the wire to pass between the left-side clamping blocks 22 and then be held between the front clamping blocks 22. This keeps the wire horizontal, making it easier to press it downwards into the slot 251. After each winding, the wire needs to be cut. Therefore, once the wire pulling block 501 moves to the initial position on the right, the first motor 3 can be turned off, stopping the wire pulling block 501. At this point, the wire is wound between the top of the winding rod 7 and the right side of the top of the abutment plate 40, and is at the bottom of the left-side clamping block 22. Then... The third motor 37 is activated, driving the first gear 36 to rotate counterclockwise. Simultaneously, the first gear 36 drives the rack frame 35 downwards and the fourth rack 41 upwards. The fourth rack 41 drives the abutment plate 40 upwards, which in turn pulls the line upwards towards the clamping blocks 22 on the left. Simultaneously, the rack frame 35 drives the cutter 34 downwards. The cutter 34 first moves to the left along the inclined rail until it is directly above the line, then descends along the vertical rail to cut the line. The action between the abutment plate 40 and the cutter 34 achieves automatic line cutting. Furthermore, after the line moves to between the two clamping blocks 22 on the left, the second rack 38 descends and engages with the one-way gear 381, driving the one-way gear 381 to rotate. When the one-way gear 381 rotates, it causes the rotating rod 221 to rotate, which in turn causes the two clamping blocks 22 on the left to move inward and clamp the line. Then, the third motor 37 is controlled to operate in reverse, driving the first gear 36 to rotate clockwise, thereby causing the abutment plate 40 to descend and reset, and the cutter 34 and the second rack 38 to move upward and reset. At this time, the one-way gear 381 rotates freely, and the clamping blocks 22 still clamp the line. Subsequently, during the process of releasing the take-up reel 8, the pulling member 18 drives the first rack 31 to move to the right. The first rack 31 then drives the one-way gear 30 to rotate 90°, causing the one-way gear 30 to drive the rotating member 20 to rotate 90° counterclockwise. In this way, the line clamped by the left clamping block 22 can be bypassed and moved to the front position. The position is set so that the next winding operation can be carried out. With the cooperation between the elastic locking post 32 and the locking hole, the position of the rotating part 20 after rotation can be restricted, preventing the rotating part 20 from rotating at will. During the movement of the wire end driven by the clamping block 22, the wire rod 26 will collide with the clamping block 22. Therefore, when the rotating part 20 rotates, the rotating part 20 will drive the wedge-shaped ring block 29 to rotate. After the wedge-shaped ring block 29 contacts the pressing post 28, it will push the pressing post 28 forward and backward, so that the wire rod 26 moves backward to avoid the clamping block 22 that has rotated to the front. At this time, the third spring 27 is compressed. When the wedge-shaped ring block 29 and the pressing post 28 separate, under the action of the third spring 27, the wire rod 26 and the pressing post 28 move forward to reset.

[0040] like Figure 1 and Figure 8 As shown, it also includes a third rack 39, which is fixedly connected to the right side of the base 1, and the third rack 39 meshes with a one-way gear 381.

[0041] In addition, as mentioned earlier, after the clamping block 22 presses the wire into the slot 251, it is necessary to manually rotate the rotating rod 221 to release the wire from the clamping block 22, which is quite troublesome. Therefore, a third rack 39 is provided. When the clamping block 22, the rotating rod 221, and the one-way gear 381 descend, the one-way gear 381 and the third rack 39 mesh, causing the one-way gear 381 to rotate and drive the rotating rod 221 to rotate. The rotating rod 221 will then drive the twisted thread to rotate, thereby causing the clamping block 22 to move outward and automatically release the wire. When the one-way gear 381 moves upward and resets, under the action of the third rack 39, the one-way gear 381 will rotate freely, keeping the clamping block 22 in an open state.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
