Description

A saddle-shaped coil winding device Technical Field

[0001] This utility model relates to the technical field of winding equipment, and in particular to a saddle-shaped coil winding device. Background Technology

[0002] Saddle-shaped coils, also known as saddle coils or cosθ-type coils, are a type of superconducting coil. They are called saddle-shaped coils because their shape resembles a saddle. Saddle-shaped coils are commonly used in fields such as motors, particle accelerators, and superconducting magnets.

[0003] Taking a saddle-shaped coil wound with superconducting wire as an example, the winding process of a saddle-shaped coil is relatively complex and cumbersome. When the superconducting wire is wound into a saddle-shaped coil, due to the limitations of the coil shape, the superconducting wire will bend and deform along the coil. In some areas, the superconducting wire may even twist. When the superconducting wire bends and deforms, it will generate a spring force. The spring force will cause the superconducting wire to spring back and detach from the preset winding position or arrangement position, resulting in a deviation between the actual shape of the coil and the design shape, which may lead to the problem of coil winding failure. Especially for square superconducting wire, the cross-section of the superconducting wire is more likely to spring back and twist when winding into a saddle-shaped coil, which can easily lead to winding failure.

[0004] Therefore, when winding saddle-shaped coils, there is a problem that the superconducting wire is prone to springing back and detaching from the preset winding position or arrangement, which can easily lead to winding failure of the saddle-shaped coil. Summary of the Invention

[0005] The purpose of this application is to solve the problem in the prior art that when winding saddle-shaped coils, the superconducting wire is prone to springing back and detaching from the preset winding station or arrangement position, which leads to the easy failure of winding saddle-shaped coils.

[0006] To solve the above-mentioned technical problems, the present invention discloses a saddle-shaped coil winding device, including a winding skeleton, a saddle-shaped wire groove on the outer peripheral wall of the winding skeleton, an inner ring skeleton in the middle of the saddle-shaped wire groove, and a plurality of groove segments connected sequentially along its circumference in the saddle-shaped wire groove. Furthermore, a plurality of pressing components are arranged circumferentially in each groove segment, and each pressing component can move perpendicular to the peripheral edge of the corresponding groove segment to press the superconducting wire entering the groove segment to fit against the bottom of the groove segment.

[0007] The clamping assembly includes a mounting part and a clamping part. The mounting part is fixedly mounted on the winding bobbin, and the clamping part is movably mounted on the mounting part. Furthermore, the clamping part can switch between a clamped state and a separated state relative to the superconducting wire within the slot. In the clamped state, the end of the clamping part faces the slot and is in contact with the outer periphery of the superconducting wire entering the slot; in the separated state, the end of the clamping part is separated from the superconducting wire.

[0008] The clamping part includes a first clamping component and a second clamping component. The first clamping component presses the top wall of the superconducting wire entering the slot in the same direction as the radial direction of the winding skeleton, and the second clamping component presses the side wall of the superconducting wire entering the slot towards the inner ring skeleton in the same direction as the axial direction of the winding skeleton.

[0009] By adopting the above technical solution, when winding a saddle-shaped wire groove, the superconducting wire is first filled into the groove segment. Then, by moving and directly pressing the superconducting wire located in the groove segment through the pressing component set around the groove segment, the superconducting wire is made to fit tightly against the bottom of the groove segment. The superconducting wire is fixed and confined within the groove segment and fits against the bottom of the groove, avoiding phenomena such as springback or twisting of the superconducting wire. This ensures that the superconducting wire is stably located in the preset winding position or arrangement position within the groove segment, thereby improving the winding success rate of the saddle-shaped coil.

[0010] Specifically, the first clamping component of the clamping part presses the top wall of the superconducting wire entering the slot section in the same direction as the radial direction of the winding skeleton, and the second clamping component presses the side wall of the superconducting wire entering the slot section towards the inner ring skeleton in the same direction as the axial direction of the winding skeleton. That is, the two side walls of the superconducting wire in the slot section are clamped from two mutually perpendicular directions, so that the superconducting wire is stably clamped in the slot section. Because the superconducting wire is clamped from both the top wall and the side wall and the degree of freedom of the superconducting wire is restricted, the superconducting wire will not spring back or twist. In particular, for superconducting wire with a square cross-section, this clamping method can fit the top wall and the side wall of the superconducting wire, resulting in a better clamping effect and solving the problem that square superconducting wires are prone to springback or twisting, which leads to failure.

[0011] Furthermore, the saddle-shaped groove for winding the saddle-shaped coil includes multiple groove segments connected sequentially along its circumference. By adjusting the groove segments, the winding of saddle-shaped coils of different shapes and sizes can be achieved, thus improving the versatility and adaptability of the winding device.

[0012] Furthermore, the clamping part can clamp the superconducting wire that enters the slot section. Since the saddle-shaped coil has a large number of turns, when one turn of superconducting wire is wound and the next turn of superconducting wire needs to be wound, the clamping part is switched to the separation state to separate it from the superconducting wire and continue to clamp and press against the next turn of superconducting wire, thereby realizing the winding of multiple turns of superconducting wire.

[0013] This utility model also discloses a saddle-shaped coil winding device. The end of the pressing part is provided with a pushing member. The pushing member extends along the length of the slot segment and has a pressing wall and an abutting wall on the side near the outer periphery of the superconducting wire. In the pressing state, the pressing wall, as a first pressing member, abuts against the top wall of the superconducting wire pressed into the slot segment, causing the superconducting wire to adhere to the bottom wall of the slot segment. The abutting wall, as a second pressing member, abuts against the side wall of the superconducting wire pressed into the slot segment towards the inner ring skeleton, causing the superconducting wire to adhere to the inner peripheral wall of the slot segment.

[0014] By adopting the above technical solution, the pressing wall and the abutting wall of the pushing component can simultaneously abut against the top wall and side wall of the superconducting wire, and abut against and limit the superconducting wire from two directions, so as to stably install and fix the superconducting wire in the slot section, avoid the superconducting wire from springing back or twisting, and further improve the winding accuracy.

[0015] The present invention also discloses a saddle-shaped coil winding device, which further includes a pushing component. The pushing component is located in a corresponding slot segment, on the side close to the inner ring skeleton. The end of the pushing component away from the inner ring skeleton can move perpendicular to the corresponding part of the inner ring skeleton.

[0016] Furthermore, the end of the pressing part is provided with a pressing member, which extends along the length of the groove segment and has a pressing wall on the side near the outer periphery of the superconducting wire. In the pressing state, the pressing wall, as a first pressing member, abuts against the top wall of the superconducting wire pressed into the groove segment, causing the superconducting wire to adhere to the bottom wall of the groove segment. Additionally, the side of the pushing component near the outer periphery of the superconducting wire, as a second pressing member, abuts against the side wall of the superconducting wire pressed into the groove segment towards the inner ring skeleton, causing the superconducting wire to adhere to the inner peripheral wall of the groove segment.

[0017] By adopting the above technical solution, the superconducting wire located in the slot section is restricted by setting up a pressing component and a pushing component, and then restricting the superconducting wire from the top wall and side wall of the superconducting wire. Similarly, the superconducting wire is restricted by the top wall and side wall of the superconducting wire to prevent the superconducting wire from springing back or twisting, thereby improving the winding accuracy of the saddle-shaped coil.

[0018] This utility model also discloses a saddle-shaped coil winding device. The pushing assembly includes a contact member and an adjusting member. The contact member extends along the length of the slot segment and has a contact wall facing the sidewall of the superconducting wire. One end of the adjusting member is connected to the contact member, and the other end is connected to the inner ring skeleton. The adjusting member can drive the contact member to adjust perpendicularly to the corresponding part of the inner ring skeleton.

[0019] The present invention also discloses a saddle-shaped coil winding device, wherein the adjusting component includes a pair of adjusting screws spaced apart on the abutting member, one end of each adjusting screw is connected to the corresponding abutting member, and the other end is threaded to the inner ring skeleton.

[0020] By adopting the above technical solution, the adjustment screw can be set up for convenient and quick adjustment. The adjustment screw can adjust the position of the pushing component in the saddle-shaped groove according to the needs, so as to restrict the superconducting wire in each loop of the groove.

[0021] The present invention also discloses a saddle-shaped coil winding device, wherein the winding frame is configured as a circular frame, and the saddle-shaped wire groove is provided on the outer peripheral wall of the winding frame extending circumferentially along the winding frame. Furthermore, one of the multiple slot segments is provided with a wire inlet slot on one side, which is provided on the outer peripheral wall of the winding frame extending circumferentially along the winding frame and connected at one end to a slot segment.

[0022] Using the above technical solution, the saddle-shaped wire groove extends circumferentially along the winding skeleton and is set on the outer peripheral wall. The outer peripheral wall of the winding skeleton provides a path for coil winding. In addition, the wire inlet groove extends circumferentially along the winding skeleton and is connected to the groove section at one end, so as to facilitate the superconducting wire to enter the saddle-shaped wire groove for winding.

[0023] The present invention also discloses a saddle-shaped coil winding device, wherein two saddle-shaped wire grooves are provided, and the two saddle-shaped wire grooves are arranged alternately on the outer peripheral wall of the winding skeleton.

[0024] Using the above technical solution, the two saddle-shaped wire grooves can be wound simultaneously, which can improve the winding efficiency.

[0025] The present invention also discloses a saddle-shaped coil winding device, wherein the clamping component is configured as a quick clamp, the quick clamp includes a clamp seat as a mounting part and a clamping mechanism as a clamping part, the clamping mechanism includes a rotating connecting plate, a pressure arm and a handle.

[0026] The clamp seat is fixedly set on the outer periphery of the winding bobbin and at the position corresponding to the corresponding slot segment. The rotating connecting plate is rotatably set on the clamp seat. One end of the pressure arm is rotatably connected to the end of the rotating connecting plate away from the clamp seat, and the other end extends toward the slot segment and has a clamping end extending toward the slot segment. One end of the handle is rotatably connected to the rotating connecting plate and is rotatably connected to one end of the pressure arm. The clamping end can move along the pressure arm.

[0027] Using the above technical solution, the quick-release clamp design allows operators to quickly tighten or loosen the coil within the slot using a simple handle. Operators can adjust the clamping arm to the most suitable angle based on the actual shape and winding condition of the coil within the slot, ensuring the clamping end accurately presses onto the required area of ​​the superconducting wire. This guarantees a uniform and reliable clamping effect, preventing coil deformation or loosening due to uneven clamping.

[0028] The present invention also discloses a saddle-shaped coil winding device, wherein end flanges are fixedly provided at both ends of the winding skeleton along the axial direction, and a rotating shaft is provided in the middle of the end flanges. The rotating shaft is coaxially arranged with the winding skeleton and extends out of the winding skeleton along the axial direction.

[0029] Using the above technical solution, the rotating shaft can rotate as needed during winding and drive the winding frame to rotate, thereby meeting the winding requirements.

[0030] In summary, this application discloses a saddle-shaped coil winding device. A saddle-shaped wire groove is formed on the outer peripheral wall of the winding skeleton. The saddle-shaped wire groove includes multiple slot segments connected sequentially along its circumference. Multiple clamping components (quick clamps) are arranged circumferentially on each slot segment. When winding the saddle-shaped wire groove, the clamping components can quickly and stably press the superconducting wire located in the slot segment, fix the superconducting wire in place and confine it within the slot segment, and avoid phenomena such as springback and twisting of the superconducting wire, thereby improving the winding power and winding efficiency of the saddle-shaped coil.

[0056] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0057] This embodiment discloses a saddle-shaped coil winding device. Please refer to Figure 1. The winding device includes a winding frame 100, and a saddle-shaped groove 110 is formed on the outer peripheral wall of the winding frame 100. It should be noted that in this embodiment, the saddle-shaped groove 110 is formed on the outer peripheral wall of the winding frame 100 and is lower than the outer peripheral wall of the winding frame 100. The depth of the saddle-shaped groove 110 is designed according to the requirements to ensure that the superconducting wire 300 can be stably embedded in the saddle-shaped groove 110 to form a single-layer coil or a multi-layer coil.

[0058] Please refer to Figures 1 and 2. An inner ring skeleton 120 is provided in the middle of the saddle-shaped wire groove 110. After the saddle-shaped coil 500 is wound within the saddle-shaped wire groove 110, the inner ring skeleton 120 abuts against the saddle-shaped coil 500. Referring to Figure 2, the saddle-shaped wire groove 110 includes multiple slot segments 111 connected sequentially along its circumference. This structural design allows for the winding of saddle-shaped coils of different shapes and sizes by adjusting the length of the slot segments 111. For example, adjusting the slot segments can accommodate saddle-shaped coils of square or other polygonal shapes, thus improving the versatility and adaptability of the winding device.

[0059] Referring further to Figure 1, each slot segment 111 is provided with multiple clamping components 200 in the circumferential direction. Each clamping component 200 can move perpendicular to the circumferential edge of the corresponding slot segment 111. The clamping component 200 can press the superconducting wire 300 that enters the slot segment 111 to fit against the bottom of the slot segment 111.

[0060] The clamping assembly 200 includes a mounting portion 210 and a clamping portion 220. The mounting portion 210 is fixedly mounted on the winding bobbin 100, and the clamping portion 220 is movably mounted on the mounting portion 210. Furthermore, the clamping portion 220 can switch between a clamped state and a separated state relative to the superconducting wire 300 within the slot segment 111. In the clamped state, the end of the clamping portion 220 faces the slot segment 111 and is in contact with the outer periphery of the superconducting wire 300 entering the slot segment 111; in the separated state, the end of the clamping portion 220 is separated from the superconducting wire 300.

[0061] The clamping part 220 includes a first clamping component (not shown in the figure) and a second clamping component (not shown in the figure). The first clamping component presses the top wall 310 of the superconducting wire entering the slot section 111 in the same direction as the radial direction of the winding skeleton 100. The second clamping component presses the side wall 320 of the superconducting wire 300 entering the slot section 111 towards the inner ring skeleton in the same direction as the axial direction of the winding skeleton 100.

[0062] With this structural design, in this embodiment, the clamping part 220 of the clamping assembly 200 clamps the superconducting wire 300 that enters the slot section 111. The clamping part 220 is configured to switch between a clamping state and a separating state relative to the superconducting wire 300 in the slot section 111. Because the saddle-shaped coil 500 has a large number of turns, when one turn of the superconducting wire 300 is wound and the next turn of the superconducting wire 300 needs to be wound, the clamping part 220 and the superconducting wire 300 are separated, and the clamping part continues to press against the next turn of the superconducting wire 300, thereby realizing the winding of the saddle-shaped coil 500.

[0063] Specifically, in this application, the first pressing component of the pressing part 220 presses the top wall of the superconducting wire 300 entering the slot section 111 in the same direction as the radial direction of the winding frame 100, and the second pressing component presses the side wall 320 of the superconducting wire 300 entering the slot section 111 towards the inner ring frame in the same direction as the axial direction of the winding frame 100. That is, the two side walls of the superconducting wire 300 located in the slot section 111 are pressed from two mutually perpendicular directions (radial and axial), so that the superconducting wire 300 is stably pressed and fixed in the slot section 111. And because the superconducting wire 300 is pressed from both sides of the top wall and side wall and the degree of freedom of the superconducting wire is restricted, the superconducting wire 300 will not spring back or twist. In particular, for superconducting wires with square cross-sections, this pressing method can fit with the top wall and side wall of the superconducting wire, and the pressing effect is better, solving the problem that square superconducting wires are prone to spring back or twist, leading to failure.

[0064] It should be noted that, because the clamping part of the winding device disclosed in this embodiment clamps the superconducting wire in both axial and radial directions, it not only has a good clamping effect on square superconducting wires, but also on round superconducting wires and other shapes of superconducting wires, thus avoiding springback or twisting during winding.

[0065] Furthermore, in this embodiment, the saddle-shaped wire groove 110 with four slot segments 111 is used as an example for illustration. The length of the four slot segments 111 can be designed according to the needs of different coils. For example, referring to Figure 2, in this embodiment, two slot segments 111 are longer and two slot segments 111 are shorter. The four slot segments 111 are connected in sequence to form the completed saddle-shaped wire groove 110.

[0066] Specifically, the number of clamping components 200 arranged circumferentially in each slot segment 111 can be 2, 3, 6 or even more. For example, referring to Figure 1, in this embodiment, fewer clamping components 200 are arranged on the side of the shorter slot segment 111, and more clamping components 200 are arranged on the side of the longer slot segment 111, so as to achieve stable pressing and fixing of the superconducting wire.

[0067] When winding the saddle-shaped coil 500 using the winding device disclosed in this embodiment, the superconducting wire 300 is first filled into the slot 111. Specifically, please refer to Figure 3. The superconducting wire 300 is filled into the outermost side of one of the slots 111, and then filled inwards sequentially. After the superconducting wire 300 is filled into the outermost side of the slot 111, the pressing component 200 arranged circumferentially in the slot 111 moves and directly presses the superconducting wire 300 located in the slot 111, so that it fits tightly against the bottom of the slot 111. This fixes and confines the superconducting wire 300 within the slot 111, preventing the superconducting wire 300 from springing back, twisting, or other phenomena. To ensure the superconducting wire 300 is stably positioned in the preset winding station or arrangement position within the slot 111, the superconducting wire 300 is wound around the saddle-shaped slot 110 once, and then the second and third turns are fixed. The final saddle-shaped coil 500 is shown in Figure 4, and the removed saddle-shaped coil 500 is shown in Figure 5. When winding the saddle-shaped coil 500 using the winding device disclosed in this embodiment, the superconducting wire 300 within the slot 111 is pressed by the clamping component 200. This results in higher efficiency and better stability when the superconducting wire 300 is wound into a saddle shape, thus further improving the winding success rate of the saddle-shaped coil 500.

[0068] Furthermore, the specific structure of the clamping assembly 200 disclosed in this embodiment is not limited, and it can be any one of a hydraulic clamping assembly, a bolt clamping assembly, a linkage clamping assembly, etc.

[0069] For example, taking the clamping assembly 200 in this embodiment as a bolt clamping assembly, the bolt clamping assembly includes a clamping bolt, a bolt plate, and a clamping plate (as a clamping part 220). The clamping bolt passes through the bolt plate and fixes the bolt plate on the winding frame 100. A spring is sleeved on the clamping bolt at the lower end of the bolt plate. The clamping plate is located at the end of the bolt plate away from the clamping bolt and facing the superconducting wire 300 in the slot section 111. When the bolt clamping assembly is in the clamping state, the clamping bolt is tightened and drives the clamping plate to abut against the superconducting wire 300 through the bolt plate. When the bolt clamping assembly is in the disengaged state, the clamping bolt is loosened and the clamping plate separates from the superconducting wire 300.

[0070] For example, taking the clamping assembly 200 as a linkage-type clamping assembly, the linkage-type clamping assembly can be a quick clamp 250, with the clamping part 220 disposed at the end of the quick clamp 250. When the quick clamp 250 is in the clamping state, the clamping part 220 abuts and is fixed to the superconducting wire 300. When the quick clamp 250 is in the disengaged state, the clamping part 220 is separated from the superconducting wire 300.

[0071] Please refer to Figure 6. When the clamping assembly 200 is set as a quick clamp 250, the quick clamp 250 includes a clamp seat 251 as a mounting part 210 and a clamping mechanism as a clamping part 220. The clamping mechanism includes a rotating connecting plate 252, a pressure arm 253 and a handle 254.

[0072] The clamp seat 251 is fixedly disposed on the outer periphery of the winding bobbin 100 at a position corresponding to the corresponding slot segment 111. The rotating connecting plate 252 is rotatably disposed on the clamp seat 251. One end of the pressure arm 253 is rotatably connected to the end of the rotating connecting plate 252 away from the clamp seat 251, and the other end extends toward the slot segment 111 and has a clamping end extending toward the slot segment 111. For example, the clamping end can be set as a clamping bolt. One end of the handle 254 is rotatably connected to the rotating connecting plate 252 and rotatably connected to one end of the pressure arm 253. Furthermore, the clamping end can move along the pressure arm 253. It should be noted that, referring to Figure 6, in the state shown in Figure 6, the quick clamp 250 is in the clamping state. When it is necessary to adjust to the disengagement state, the handle 254 is rotated counterclockwise to make the quick clamp 250 disengage.

[0073] With this structural design, the quick clamp 250 is actually a clamping mechanism. The principle of quick clamping is to form a dead point self-locking through the linkage mechanism in the clamping state to prevent loosening, which will not be elaborated further in this embodiment. The design of the quick clamp 250 allows the operator to quickly clamp or loosen the superconducting wire 300 in the slot section 111 by operating the simple handle 254. Compared with some traditional complex clamping devices, there is no need for cumbersome bolt tightening or loosening operations, saving operation time and improving the efficiency of winding work. The operator can adjust the clamping arm 253 to the most suitable angle according to the actual shape of the superconducting wire 300 in the slot section 111 and the winding situation, so that the clamping end can accurately press on the part of the superconducting wire 300 that needs to be clamped, ensuring uniform and reliable clamping effect and avoiding coil deformation or loosening due to uneven clamping.

[0074] It should be noted that the quick clamp 250 in this embodiment can also be other common clamping structures, which will not be described in detail in this embodiment.

[0075] In this embodiment, the superconducting wire 300 is square. A square superconducting wire 300 is more prone to twisting and springback when wound into a saddle-shaped coil 500. When the square superconducting wire 300 is inserted into one side of the slot 111, two side walls of the square superconducting wire 300 abut against the bottom and side walls of the slot 111, respectively. The top wall 310 and the side wall 320 facing the inner ring skeleton are exposed. Therefore, in this embodiment, by providing the pressing part 220, the top wall 310 and the side wall 320 facing the inner ring skeleton of the superconducting wire can be stably pushed and pressed, ensuring that all four side walls of the square superconducting wire 300 are abutted and pressed, thereby ensuring that the superconducting wire 300 located in the slot 111 is in a stable state and will not spring back or twist. The following will explain how to push and press the top wall 310 and the side wall 320 facing the inner ring skeleton of the superconducting wire.

[0076] In one configuration, the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton are pressed and abutted by a component. Referring to Figure 7, a pushing member 230 is provided at the end of the pressing part 220. The pushing member 230 extends along the length of the groove segment 111. The side of the pushing member 230 near the outer periphery of the superconducting wire 300 has a crimping wall 231 and an abutting wall 232. Specifically, referring to Figure 7, the cross-sectional view of the pushing member 230 is shaped like the number "7". The crimping wall 231 and the abutting wall 232 face the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton, respectively.

[0077] With such a structure, in the compressed state, the crimping wall 231 acts as the first crimping component, abutting against the top wall 310 of the superconducting wire that is pressed into the groove segment 111, so that the superconducting wire 300 fits against the bottom wall of the groove segment 111, and the abutting wall 232 acts as the second crimping component, abutting against the side wall 320 of the superconducting wire 300 that is pressed into the groove segment 111 towards the inner ring skeleton, so that the superconducting wire 300 fits against the inner peripheral wall of the groove segment 111.

[0078] With this structural design, the pressing wall 231 and the abutting wall 232 of the pushing member 230 can simultaneously abut against the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton, thereby abutting and limiting the superconducting wire 300 from two directions, stably installing and fixing the superconducting wire 300 in the slot section 111, preventing the superconducting wire 300 from springing back or twisting, and further improving the winding accuracy.

[0079] In another configuration, the top wall 310 of the superconducting wire and the side wall 320 facing the inner coil frame are pressed and abutted by two components, as shown in Figure 8. The saddle-shaped coil winding device also includes a pushing assembly 400, which is located in a corresponding slot 111, near the inner coil frame 120. The end of the pushing assembly 400 away from the inner coil frame 120 can move perpendicularly to the corresponding part of the inner coil frame 120. Furthermore, the end of the pressing part 220 is provided with a pressing member 240, which extends along the length of the slot 111 and has a pressing wall on the side near the outer periphery of the superconducting wire 300.

[0080] In the compressed state, the compression wall, as the first compression member, abuts against the top wall 310 of the superconducting wire that is pressed into the groove 111, so that the superconducting wire 300 fits against the bottom wall of the groove 111. Furthermore, the side of the pushing assembly 400 near the outer periphery of the superconducting wire 300, as the second compression member, abuts against the side wall 320 of the superconducting wire 300 that is pressed into the groove 111 toward the inner ring skeleton, so that the superconducting wire 300 fits against the inner peripheral wall of the groove 111.

[0081] This structural design, by setting up the pressing member 240 and the pushing component 400 to cooperate, restricts the superconducting wire 300 located in the slot section 111 from the top wall 310 and side wall of the superconducting wire. Similarly, the superconducting wire 300 is restricted from the top wall 310 and the side wall 320 facing the inner ring skeleton, so as to prevent the superconducting wire 300 from springing back or twisting, thereby improving the winding accuracy of the saddle-shaped coil 500.

[0082] Preferably, referring to FIG8, the push assembly 400 includes abutment member 410 and adjustment member. The abutment member 410 extends along the length direction of the groove segment 111 and has an abutment wall 232 facing the sidewall of the superconducting wire 300. One end of the adjustment member is connected to the abutment member 410 and the other end is connected to the inner ring frame 120. The adjustment member can drive the abutment member 410 to adjust perpendicularly to a corresponding part of the inner ring frame 120.

[0083] In this embodiment, the adjusting component is not limited, and can be, for example, a screw, a lead screw, etc. In this embodiment, the abutting member 410 is preferably configured as an abutting strip, which can abut against and press the side wall 320 of the superconducting wire 300 facing the inner ring skeleton. Similarly, the pressing member 240 is configured as a pressing strip and abuts against and presses the top wall 310 of the superconducting wire 300.

[0084] More preferably, referring to FIG8, the adjusting component includes a pair of adjusting screws 420 spaced apart on the abutting member 410, one end of each adjusting screw 420 being connected to the corresponding abutting member 410, and the other end being threadedly connected to the inner ring skeleton 120.

[0085] With this structural design, the adjustment screw 420 can be set up for convenient and quick adjustment. The adjustment screw 420 can adjust the position of the abutment member 410 in the saddle-shaped wire groove 110 as needed, so as to restrict the superconducting wire 300 in each loop of the groove segment 111 in the saddle-shaped wire groove 110.

[0086] It should be noted that in this embodiment, different types of pushing members can be set in the four slots 111 to press the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton, as needed. For example, the superconducting wires 300 in the four slots 111 can all be pressed and abutted against the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton by a single member. Or, for another example, the superconducting wires 300 in the four slots 111 can all be pressed and abutted against the top wall 310 of the superconducting wire by two members. For example, in a longer slot 111, the superconducting wire 300 presses and abuts against the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton through two components, while in a shorter slot 111, the superconducting wire 300 presses and abuts against the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton through one component. Those skilled in the art can design and select according to actual needs, and this embodiment does not make specific limitations in this regard.

[0087] This embodiment also discloses a saddle-shaped coil winding device. Referring to Figure 2, the winding frame 100 is configured as a circular frame, and the saddle-shaped wire groove 110 extends circumferentially along the outer peripheral wall of the winding frame 100. Furthermore, one of the multiple groove segments 111 has an inlet groove 112 on one side. The inlet groove 112 extends circumferentially along the outer peripheral wall of the winding frame 100 and is connected at one end to one groove segment 111.

[0088] It should be noted that the inlet slot 112 can be set on the side of the longer slot segment 111 or on the side of the shorter slot segment 111. In this embodiment, the inlet slot 112 is preferably set on the side of the longer slot segment 111.

[0089] With this structural design, the saddle-shaped wire groove 110 extends circumferentially along the outer peripheral wall of the winding skeleton 100, providing a path for coil winding on the outer peripheral wall of the winding skeleton 100. Furthermore, the wire inlet groove 112 extends circumferentially along the winding skeleton 100 and is connected at one end to the groove segment 111, providing a dedicated channel for the superconducting wire 300 to enter the wire groove, facilitating the superconducting wire 300 to enter the saddle-shaped wire groove 110 for winding.

[0090] The present invention also discloses a saddle-shaped coil winding device. Please refer to Figure 1. Two saddle-shaped wire grooves 110 are provided, and the two saddle-shaped wire grooves 110 are arranged at intervals on the outer peripheral wall of the winding skeleton 100.

[0091] With this structural design, the two saddle-shaped grooves 110 can perform winding operations simultaneously, which can improve winding efficiency.

[0092] The present invention also discloses a saddle-shaped coil winding device. Please refer to Figure 1. End flanges 130 are fixedly provided on both axial ends of the winding skeleton 100. A rotating shaft 140 is also provided in the middle of the end flanges 130. The rotating shaft 140 is coaxially arranged with the winding skeleton 100 and extends out of the winding skeleton 100 along the axial direction.

[0093] With this structural design, the rotating shaft 140 can rotate as needed during winding and drive the winding frame 100 to rotate to meet the winding requirements.

[0094] In summary, this application discloses a saddle-shaped coil winding device. A saddle-shaped wire groove 110 is formed on the outer peripheral wall of the winding skeleton 100. The saddle-shaped wire groove 110 includes multiple slot segments 111 connected sequentially along its circumference. Multiple clamping components 200 (quick clamps 250) are arranged circumferentially on each slot segment 111. When winding the saddle-shaped wire groove 110, the clamping components 200 can quickly and stably press the superconducting wire 300 located in the slot segment 111, fix the superconducting wire 300 and confine it in the slot segment 111, and avoid the superconducting wire 300 from springing back, twisting and other phenomena, thereby improving the winding power and winding efficiency of the saddle-shaped coil 500.

[0095] Finally, a brief description is given of the winding process of the saddle-shaped coil 500 using the saddle-shaped coil winding device disclosed in this utility model:

[0096] First, before winding the saddle-shaped coil 500, prepare the tooling by clamping the winding bobbin 100 between the two end flanges 130, so that the rotating shaft 140 passes through the two end flanges 130 and the center of the winding bobbin 100, and use bolts to fasten the winding bobbin 100, the two end flanges 130 and the rotating shaft 140 into a whole winding tooling, and then install the entire winding tooling onto the winding machine.

[0097] As shown in Figures 1 and 2, the saddle-shaped groove 110 on the outer peripheral wall of the winding skeleton 100 has four groove segments 111 and one inlet groove 112. Two of the four groove segments 111 are longer and two are shorter. The inlet groove 112 is connected to one of the longer groove segments 111. The wound superconducting wire 300 is a superconducting wire 300 with a square cross-section.

[0098] Please refer to Figure 3. When winding needs to begin, the superconducting wire 300 enters the saddle-shaped wire groove 110 from the inlet groove 112. The inlet groove 112 can guide the superconducting wire 300. After entering the saddle-shaped wire groove 110, the superconducting wire first abuts against the longer section 111 of the saddle-shaped wire groove 110. The bottom wall of the superconducting wire 300 abuts against the bottom wall of the section 111 of the saddle-shaped wire groove 110, and one side wall abuts against the side wall of the longer section 111 of the saddle-shaped wire groove 110. At this time, the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton are exposed. At this time, it is also necessary to press the superconducting wire 300 along the radial and axial directions of the winding skeleton 100, that is, to press the top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton. Referring to Figure 8, the pressing member 240 at the end of the pressing part 220 of the pressing assembly 200 presses the top wall 310 of the superconducting wire radially, and the pushing member 230 (rotary adjusting screw 420) of the pushing assembly 400 presses against the side wall 320 of the superconducting wire 300 facing the inner ring skeleton. At this time, all four outer walls of the superconducting wire 300 located in the long groove section 111 are stably pressed against, preventing the superconducting wire 300 from springing back or twisting.

[0099] Then, the superconducting wire 300 is filled into the adjacent shorter slot 111. Referring to Figures 1 and 7, the bottom wall of the superconducting wire 300 abuts against the bottom wall of the shorter slot 111, and one side wall abuts against the side wall of the slot 111. The top wall 310 of the superconducting wire and the side wall 320 facing the inner ring skeleton are pressed and abutted by a component. Referring to Figure 7, the pressing wall 231 of the pushing component 230 presses against the top wall 310 of the superconducting wire, and the pressing wall 232 presses against the side wall 320 of the superconducting wire 300 facing the inner ring skeleton, so that the four outer walls of the superconducting wire 300 located in the shorter slot 111 are stably pressed and abutted. Then, it is sequentially filled into the remaining longer slot 111 and the shorter slot 111 to complete the winding of the outermost ring.

[0100] After the outermost turn of the saddle-shaped coil 500 is wound, the second turn is wound in sequence. The winding method is the same for the second turn. During the winding, the clamping component 200 is separated, and then the bottom wall of the second turn of the superconducting wire 300 abuts against the bottom of the saddle-shaped wire groove 110, and one side wall abuts against the first turn of the superconducting wire 300. Then the second and third turns are wound in sequence. During the winding process, the steps of winding, clamping, loosening, shifting, and clamping are repeated until all the turns and loops in the coil are completed. The superconducting wire 300 finally wound in the saddle-shaped wire groove 110 is shown in Figure 4, and the saddle-shaped coil 500 is finally taken out as shown in Figure 5.
