Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a foil winding limit device for preventing displacement of high and low voltage foil winding coils. Background Technology

[0002] Foil coils are made of one or more wires wound together, and are a type of layered coil. Unlike cylindrical coils, foil coils use thin and wide copper or aluminum foil as conductors, with only one turn axially and multiple turns radially, resulting in an axial oil gap after several turns. This structure is mainly used in low-voltage, small-capacity transformers, offering advantages such as good mechanical strength, resistance to deformation, ability to withstand short-circuit forces, good electrical strength, uniform distribution of impulse voltage gradients, and ease of winding.

[0003] When winding coils, the copper or aluminum busbars of the outer coil must be fixedly connected to the winding spindle so that the foil winding machine can wind the wires onto the copper or aluminum busbars to form a coil. In the existing technology, the copper busbars lack corresponding limiting devices, and are usually placed on the coil by hand, automatically fixed by the extrusion pressure during coil winding. This can easily cause the copper busbars to shift, affecting the production quality of foil-wound coils.

[0004] To address this issue, we propose a high- and low-voltage foil-wound coil anti-displacement foil-wound limiting device to solve the problem in existing technologies where the copper busbar of foil-wound coils is prone to displacement, affecting coil production quality. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a foil winding limit device for preventing displacement of high and low voltage foil winding coils, which is used to solve the problem that the copper busbar of foil winding coils is prone to displacement in the prior art, affecting the quality of coil production.

[0006] To achieve the above and other related objectives, this utility model provides a high and low voltage foil winding coil anti-displacement foil winding limiting device, including: a mounting base and a clamping assembly;

[0007] The mounting base is a square tube structure, and several through holes are provided at both the left and right ends;

[0008] The clamping assembly includes a rectangular guide rail connected to the mounting base. The guide rail has a square opening in the middle, and a clamp is provided in the square opening of the guide rail for clamping and fixing the coil copper busbar. Slider blocks extend outward from both sides of the clamp, and the two sliders are respectively located on both sides of the opening inside the guide rail. A drive module is provided on the guide rail, and the drive module is used to control the two sliders to slide up and down along the two sides of the opening of the guide rail.

[0009] Preferably, the clamp includes a first locking member and a second locking member, and a telescopic member connects the first locking member and the second locking member.

[0010] Preferably, both the first locking member and the second locking member include a frame. An electric push rod is connected to the inner top of the frame. A pressing plate is connected to the lower end of the electric push rod. A bidirectional motor is connected to the middle of the pressing plate. A screw is connected to both ends of the bidirectional motor. An extension rod is slidably connected to both ends of the pressing plate. A baffle is connected to the outer ends of the two extension rods. Each screw passes through the extension rod and is threadedly connected to the extension rod.

[0011] Preferably, the telescopic member includes a sleeve connected to the outer surface of the first locking member, a push rod slidably connected to the middle of the sleeve, a knob rotatably connected to the upper end of the sleeve, the push rod passing through the knob and threadedly connected to the knob, and the top end of the push rod being connected to the second locking member.

[0012] Preferably, the drive module includes a drive motor located at the bottom of the guide rail. The drive motor is connected to two screws via pulleys. The two screws are located on the inner sides of both ends of the guide rail and are parallel to the guide rail. Each screw passes through a slider and is threadedly connected to the slider.

[0013] Preferably, each of the frames is connected to an inclined plate at its rear end, and a cylindrical pressure roller is connected to the other end of the inclined plate for pressing the external copper busbar. The inclined plate is provided with an angle adjustment module for adjusting the angle of the inclined plate.

[0014] Preferably, the angle adjustment module includes a rotating component one connected to the side of each tilting plate, an adjustment rod connected to the middle of each rotating component one, a handle connected to the lower end of each adjustment rod, and a rotating component two connected to the other end of each adjustment rod, and each rotating component two being connected to the side of a frame.

[0015] Preferably, the outer surface of the pressure roller is provided with a rubber pad to prevent the pressure roller from scratching the external copper busbar.

[0016] As described above, the high and low voltage foil winding coil anti-displacement foil winding limiting device disclosed in this utility model has the following beneficial effects: This utility model supports the clamp that can fix the copper busbar by using an external mounting seat on the square shaft of the winding coil. By inserting the outer end of the copper busbar into the frame and positioning it between the extrusion plate and the bottom of the frame, the electric push rod is activated. The electric push rod drives the extrusion plate to move downward, extruding and fixing the copper busbar. Then, the bidirectional motor is activated, which drives the screw to rotate. The screw drives the extension rod to retract, and the extension rod moves the baffles on both sides of the copper busbar toward the position of the copper busbar, providing auxiliary fixation on both sides of the copper busbar. This achieves the clamping and positioning operation of the copper busbar, preventing the copper busbar from shifting during winding. The copper busbar rotates with the square shaft, achieving automatic following during coil winding and ensuring that the copper busbar does not shift during the winding process.

[0017] Meanwhile, by setting up an inclined plate, pressure rollers, and an adjustment module, the handle is turned, which drives the adjustment rod to rotate, changing the distance between rotating part one and rotating part two. This causes the lower inclined plate to rotate around the first locking part, driving the pressure rollers to squeeze the copper busbar, further enhancing the stability of the fixed copper busbar.

[0018] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0035] like Figure 1-6 As shown, this utility model provides a foil winding anti-displacement limiting device for high and low voltage foil winding coils, including: a mounting base 1 and a clamping assembly 2;

[0036] Mounting base 1 has a square tube structure and several through holes at both ends. Mounting base 1 can be sleeved on a rotating square shaft used for coil winding. Bolts are passed through the through holes and screwed into the rotating square shaft to achieve a fixed connection between mounting base 1 and rotating square shaft.

[0037] The clamping assembly 2 includes a rectangular guide rail 20 connected to the mounting base 1. The guide rail 20 is arranged vertically and parallel to the side of the winding coil. A square opening is provided in the middle of the guide rail 20, and a clamp 21 is provided in the square opening of the guide rail 20. The clamp 21 is used to clamp and fix the copper busbar of the coil. Slider 22 extends outward on both sides of the clamp 21. The two sliders 22 are located on both sides of the opening inside the guide rail 20. A drive module 23 is provided on the guide rail 20. The drive module 23 is used to control the two sliders 22 to slide up and down along the two sides of the opening of the guide rail 20, thereby driving the clamp 21 to rise and fall, so as to facilitate the adjustment of the height position of the clamp 21 according to the installation position of the copper busbar.

[0038] In one embodiment, please refer to Figure 1 and Figure 3 The clamp 21 includes a first locking member 210 and a second locking member 211, with a telescopic member 212 connecting the first locking member 210 and the second locking member 211. During the coil winding process, two copper busbars are stacked together, with a certain distance between them. The first locking member 210 and the second locking member 211 are used to position the two copper busbars, respectively, and the telescopic member 212 is used to adjust the distance between the first locking member 210 and the second locking member 211, facilitating adjustments according to specific circumstances.

[0039] In one embodiment, please refer to Figure 3-4 Both the first locking member 210 and the second locking member 211 include a frame 30. An electric push rod 31 is connected to the top inner part of the frame 30. A pressing plate 32 is connected to the lower end of the electric push rod 31. A bidirectional motor 33 is connected to the middle of the pressing plate 32. Screws 34 are connected to both ends of the bidirectional motor 33. Extension rods 35 are slidably connected to both ends of the pressing plate 32. Baffles 36 are connected to the outer ends of the two extension rods 35. Each screw 34 passes through an extension rod 35 and is threadedly connected to it. In use, the outer end of the copper busbar is inserted into the frame 30, positioned between the pressing plate 32 and the bottom inner part of the frame 30. The electric push rod 31 is activated, causing the pressing plate 32 to move downwards, pressing and fixing the copper busbar. Then, the bidirectional motor 33 is activated, causing the screws 34 to rotate. The screws 34 retract the extension rods 35, which move the baffles 36 on both sides of the copper busbar towards the copper busbar, providing auxiliary fixing to both sides of the copper busbar. This enables the clamping and positioning of the copper busbar, preventing it from shifting during winding.

[0040] In one embodiment, please refer to Figure 3 and Figure 5 The telescopic component 212 includes a sleeve 2120 connected to the outer surface of the first locking component 210. A push rod 2121 is slidably connected to the middle of the sleeve 2120, and a knob 2122 is rotatably connected to the upper end of the sleeve 2120. The push rod 2121 passes through the knob 2122 and is threadedly connected to the knob 2122. The top end of the push rod 2121 is connected to the second locking component 211. In use, by rotating the knob 2122, the knob 2122 rotates around the push rod 2121, which drives the push rod 2121 to extend and retract along the sleeve 2120 through the thread, thereby adjusting the distance between the first locking component 210 and the second locking component 211.

[0041] In one embodiment, please refer to Figure 1-2The drive module 23 includes a drive motor 230 located at the bottom of the guide rail 20. The drive motor 230 is connected to two screws 232 via pulleys 231. The two screws 232 are located on the inner sides of both ends of the guide rail 20 and are parallel to the guide rail 20. Each screw 232 passes through a slider 22 and is threadedly connected to the slider 22. In use, by starting the drive motor 230, the drive motor 230 drives the screws 232 on both sides to rotate via the double-layer pulleys 231. The screws 232 drive the sliders 22 to slide up and down along the guide rail 20. The two sliders 22 can be fixed to the two sides of the first locking member 210, thereby achieving the effect of easy adjustment of the height of the clamp 21, which is convenient for height adjustment according to the specific installation position of the copper busbar.

[0042] In one embodiment, please refer to Figure 3 and Figure 6 Each frame 30 has an inclined plate 40 connected to its rear end, and a cylindrical pressure roller 41 connected to the other end of the inclined plate 40 for pressing the external copper busbar. The inclined plate 40 is equipped with an angle adjustment module 42 for adjusting the angle of the inclined plate 40. After the copper busbar is locked by the locking element, the angle adjustment module 42 causes the inclined plate 40 to rotate downward around the locking element, driving the pressure roller 41 to press the inclined surface of the copper busbar. This is used to enhance the stability of the fixed copper busbar.

[0043] In one embodiment, please refer to Figure 3 and Figure 6 The angle adjustment module 42 includes a rotating component 420 connected to the side of each tilting plate 40. An adjusting rod 421 is connected to the middle of each rotating component 420, passing through and threadedly connected to the rotating component 420. A handle 422 is connected to the lower end of each adjusting rod 421, and a rotating component 423 is connected to the other end of each adjusting rod 421. The adjusting rod 421 and the rotating component 423 are rotatably connected. Each rotating component 423 is connected to the side of a frame 30. In use, rotating the handle 422 causes the adjusting rod 421 to rotate, causing it to extend and retract spirally along the rotating component 420, thereby changing the distance between the rotating component 420 and the rotating component 423. This allows the rotating components 420 and 423 to rotate around the sides of the tilting plate 40 and the locking component, respectively, thus changing the angle of the tilting plate 40.

[0044] In one embodiment, please refer to Figure 3 and Figure 6 The outer surface of the pressure roller 41 is provided with a rubber pad to prevent the pressure roller 41 from scratching the external copper busbar.

[0045] The specific usage process of this utility model is as follows: Mounting base 1 is sleeved onto the rotating square shaft and fixed with bolts. Then, according to the specifications of the wound coil and the actual height of the copper busbar installation position, the drive module 23 controls the slider 22 to rise, causing the slider 22 to drive the clamp 21 to rise and match the copper busbar installation position. The outer end of the copper busbar is inserted into the first locking member 210. The electric push rod 31 is activated, causing the extrusion plate 32 to move downwards, extruding and fixing the copper busbar. Then, the bidirectional motor 33 is activated, causing the screw 34 to rotate. The screw 34 causes the extension rod 35 to retract, causing the baffles 36 on both sides of the copper busbar to move towards the copper busbar position, providing auxiliary fixing to both sides of the copper busbar, thus completing the extrusion and fixing of the copper busbar. The handle 422 is then manually rotated. 422 drives the adjusting rod 421 to rotate, changing the distance between the first rotating part 420 and the second rotating part 423, thereby causing the lower inclined plate 40 to rotate around the first locking part 210, driving the pressure roller 41 to squeeze the copper busbar, further strengthening the stability of the fixed copper busbar. After the coil is wound for a period of time, according to the actual installation position of the second copper busbar, the knob 2122 is rotated. The knob 2122 rotates around the top rod 2121, and the top rod 2121 is driven to extend and retract along the sleeve 2120 through the thread, thereby adjusting the distance between the first locking part 210 and the second locking part 211. The above copper busbar positioning steps are repeated to fix the second copper busbar and wind the coil, thereby facilitating the limitation of the copper busbar during coil winding and avoiding the effect of deviation during the winding process.

[0046] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
