Description

Technical Field

[0001] This utility model relates to the field of coil processing technology for nuclear fusion devices, specifically to an axial clamping fixture and winding device for a stellarator coil winding mold. Background Technology

[0002] Currently, in the process of stellarator coil winding, the industry generally uses traditional clamping methods to complete the coil shaping and clamping operation. This mainly relies on C-clamps for clamping or direct bolt clamping to achieve coil positioning and clamping. The traditional C-clamp and bolt clamping method has poor fault tolerance. During the clamping process, the rigid force can easily wear down and damage the fiberglass cloth protective layer on the coil surface. At the same time, the clamping operation is very likely to generate metal shavings and other impurities. These impurities can easily adhere to and fall into the coil gaps, which will not only damage the protective structure on the coil surface and affect the coil insulation performance and service life, but also reduce the overall processing quality of the coil and pose a safety hazard to equipment operation.

[0003] Moreover, most existing clamping fixtures are fixed structures, and the clamping position and clamping distance cannot be flexibly adjusted according to different specifications and sizes of coils. They cannot meet the batch processing and production needs of multi-specification coils and have poor versatility. For different models and sizes of coils, different specifications of clamping fixtures need to be replaced, which not only increases the manufacturing cost of the fixtures, but also causes the winding process to be interrupted, further restricting the improvement of production efficiency.

[0004] Therefore, the clamping fixtures in the existing technology have the problem of poor versatility. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor versatility of existing clamping fixtures.

[0006] To achieve the above objectives, this utility model provides an axial clamping fixture for a stellarator coil winding mold, comprising: a mounting base, a support base, a lever, a lifting member, and a clamping member. The mounting base is fixedly mounted on the winding mold and has a guide portion extending along a first direction. The support base has a guided portion that is slidably connected to the guide portion along the first direction, so that the support base can move relative to the mounting base along the first direction. The lever extends along the first direction and is rotatably connected to the support base. The portion of the support base rotatably connected to the lever serves as a fulcrum. The portion of the lever along its length direction located on one side of the fulcrum is a power arm, and the portion located on the other side of the fulcrum is a resistance arm. The lifting member is disposed on the power arm, and the clamping member is fixedly connected to the resistance arm and extends in a second direction perpendicular to the first direction. The lifting member is configured to drive the power arm to move away from the mounting base in the second direction while simultaneously moving the resistance arm and the clamping member toward the support base in the second direction. One end face of the clamping member along its extension direction is pressed against the top surface of the conductor inside the winding mold.

[0007] By adopting the above technical solution, when the guided part of the support seat moves on the guide part of the mounting seat, the support seat can drive the lever to move along the first direction, so that the clamping part of the lever can also move along the first direction. When using the clamping fixture, the position to be clamped can be determined according to the current position and specific structure of the conductor, and then the clamping part of the lever can be moved to that position. This setting allows the clamping fixture to adapt to the structure and position of various conductors. Therefore, in the work of clamping conductors, there is no need to frequently change the clamping fixture due to different conductor structures, which reduces the waste of processing time and improves processing efficiency.

[0008] Furthermore, after the lever's clamping element moves to the clamping position, the lifting element is then operated to drive the lever's power arm to move along the second direction away from the mounting base. The movement of the power arm can drive the lever to rotate around the fulcrum of the support base, thereby driving the resistance arm to move along the second direction towards the mounting base, and driving the clamping element of the resistance arm to clamp the conductor. This setting can convert the lifting force provided by the lifting element to the lever's power arm into the clamping force provided by the clamping element on the resistance arm to the conductor through the fulcrum. The position of the fulcrum relative to the two ends of the lever can be set according to actual needs, thereby adjusting the magnitude of the clamping force and ensuring that the clamping fixture can provide sufficient clamping force to the conductor.

[0009] In summary, the lever of this clamping fixture can be moved to a suitable clamping position on the mounting base according to the structure and position of the conductor, and the lifting component drives the lever to rotate around the fulcrum to drive the clamping component to provide clamping force to the conductor, thereby solving the problem of poor versatility of existing clamping fixtures.

[0010] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed. The guide part is a guide groove, the guided part is a protrusion, the outer sidewall of the protrusion is slidably connected to the inner sidewall of the guide groove, and the support can be limited to moving relative to the mounting base only in a first direction.

[0011] By adopting the above technical solution, it is ensured that the protrusion can slide to a suitable position along the extension direction of the guide groove according to actual needs. While taking into account mutual sliding, the outer sidewall of the protrusion and the inner sidewall of the guide groove cooperate to limit the relative position of the protrusion and the guide groove in the direction perpendicular to the guide groove wall and in the second direction to remain unchanged. This ensures that the support seat only moves relative to the mounting seat in the first direction. This setting ensures that when the lever is under force, the support seat will not move in other directions due to the force, ensuring the stability of the lever position during the clamping process. This allows the clamping fixture to provide a stable clamping force to the conductor.

[0012] In addition, this sliding connection structure, in which the protrusion and guide groove cooperate, is simple in design, easy to manufacture, and has a low processing cost.

[0013] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is provided. A portion of the mounting base along the first direction is provided with a groove-shaped structure that extends along the second direction. The clamping member passes through the groove-shaped structure along the second direction to clamp the top surface of the conductor. Guide grooves are formed on both sides of the groove-shaped structure along its width direction.

[0014] By adopting the above technical solution, this configuration allows the clamping fixture to be adapted to conductors whose clamping position is directly below the groove structure. When the conductor is directly below the groove structure, the clamping component can pass through the groove structure and clamp the conductor. The guide groove is set on both sides of the groove wall along the width direction of the groove structure, so that the guided part of the support can move inside the groove structure. This ensures that the clamping component of the lever can clamp the conductor directly below the groove structure as well as the conductor on the side of the mounting base facing the clamping component, making the clamping fixture more versatile.

[0015] In addition, the guide groove runs through the width of the groove structure. The side wall of the guide groove and the outer side wall of the protrusion cooperate to limit the relative position of the protrusion and the guide groove in the second direction to remain unchanged, so that the support will not move in the second direction during the sliding process, thereby ensuring that the support can have good operational stability.

[0016] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed. The lifting component is a fastener. The fastener passes through the lever along the second direction and is fixedly connected to the mounting base. The fastener is threadedly connected to the lever. One end face of the fastener along its extension direction abuts against the mounting base. The distance between the fastener and the fulcrum is greater than the distance between the clamping component and the fulcrum.

[0017] Using the above technical solution, one end face of the fastener along its extension direction abuts against the mounting base, so that the position of the fastener along its extension direction remains unchanged during the tightening process. The fastener and the lever are connected by threads, and the threads of the fastener engage with the threads of the lever during rotation, driving the lever to move along the extension direction of the fastener. This lifting structure only requires machining a threaded hole on the lever, which is simple in design and easy to manufacture. During operation, the fastener can be rotated in a certain direction, and the operation steps are simple.

[0018] In addition, the distance between the fastener and the fulcrum is greater than the distance between the clamping component and the fulcrum. This means that when the lifting force provided by the fastener to the lever is transmitted to the clamping component through the lever, it will be amplified. When the clamping fixture requires a larger clamping force, the position of the fulcrum can be changed to amplify the clamping force. This design enables the clamping fixture to have a better clamping effect and can adapt to working conditions that require a larger clamping force, thus having good versatility.

[0019] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed, and the fastener is a bolt.

[0020] Using the above technical solution, bolts are commonly used standard parts with mature manufacturing processes. They can ensure good rigidity while also being durable. Moreover, they are easy to procure and have low usage costs.

[0021] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed, wherein there are multiple fasteners, and the multiple fasteners are spaced apart along the length direction of the lever.

[0022] By adopting the above technical solution, multiple fasteners can provide a large lifting force to the lever when used at the same time, thereby enabling the clamping component to have a high clamping force. Furthermore, when one fastener is subjected to a large force, the other fasteners can simultaneously press against the mounting base, ensuring that the fastener will not shift due to the force.

[0023] In addition, the multiple fasteners are spaced apart along the length of the lever so that the fasteners can be adapted to multiple clamping positions of the lever's clamping element. When the clamping element of the lever is far from the mounting base, the fasteners that are far from the clamping element can be used. When the clamping element of the lever is in the groove structure area of ​​the mounting base, the fasteners that are close to the clamping element can be used. This arrangement makes the clamping fixture more versatile.

[0024] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed, wherein the cross-sectional area of ​​the end of the clamping member facing the conductor is greater than the cross-sectional area of ​​the portion of the clamping member that penetrates the resistance arm.

[0025] By adopting the above technical solution, the cross-sectional area of ​​the clamping component facing the conductor is larger, which makes the contact area between the clamping component and the conductor larger. This allows the conductor to be subjected to uniform force during the clamping process, avoids the clamping component from damaging the conductor, and thus makes the clamping fixture have a better clamping effect.

[0026] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is provided. The support base is provided with a groove. The groove opening faces away from the mounting base in the second direction. The groove is provided through in the first direction. The fulcrum is a connecting shaft. The connecting shaft passes through and connects to the two sides of the groove wall. The lever can rotate relative to the support base around the axis of the connecting shaft and is engaged between the two sides of the groove wall.

[0027] By adopting the above technical solution, the groove of the support seat can limit the movement of the lever in the direction perpendicular to the groove wall, so that the lever will not wobble due to force when rotating around the connecting shaft, thereby ensuring the stable operation of the lever and enabling the clamping fixture to provide a stable clamping force.

[0028] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed. The axial clamping fixture further includes an adjusting rod that extends along a second direction. One end of the adjusting rod is disposed on a mounting base and fixed relative to the mounting base. The adjusting rod is provided with a plurality of mounting portions spaced apart along the second direction. Some of the mounting portions are fixedly connected to the winding mold.

[0029] By adopting the above technical solution, during the use of the clamping fixture, a more suitable mounting part on the adjusting rod can be fixedly connected to the winding mold according to the required clamping height of the conductor. This setting allows the clamping fixture to be adapted to conductors of different heights, thus having better versatility.

[0030] According to the present invention, an axial clamping fixture for a stellarator coil winding mold is disclosed, wherein the adjusting rod is a hollow component and the mounting part is a mounting hole that penetrates the hollow component radially.

[0031] By adopting the above technical solution, the hollow structure of the adjusting rod can significantly reduce the weight of the adjusting rod while ensuring sufficient rigidity. This design makes it more convenient for operators to adjust the position of the clamping fixture and reduce the labor intensity of the operators. In addition, the mounting part is set as a through mounting hole structure, which is simple in design and has low manufacturing difficulty.

[0032] According to the present invention, a stellarator coil winding device includes: a winding mold and a plurality of stellarator coil winding mold axial clamping fixtures with the above-described structure. The plurality of axial clamping fixtures are arranged at intervals along the circumference of the winding mold. The first direction of the axial clamping fixtures is parallel to the radial direction of the winding mold, and the second direction is parallel to the axial direction of the winding mold.

[0033] Using the above technical solution, a conductor is provided inside the winding mold, and the clamping fixture can clamp the conductor along the circumference of the winding mold. The clamping fixture is spaced apart so that the conductor can receive relatively uniform pressure, avoiding excessive local stress on the conductor and causing damage to the conductor.

[0034] The beneficial effects of this utility model are as follows: This utility model provides an axial clamping fixture and winding device for a stellarator coil winding mold. The clamping fixture includes: a mounting base, a support base, a lever, a lifting member, and a clamping member. The mounting base is fixedly installed on the winding mold. The mounting base is provided with a guide portion extending in a first direction. The support base is provided with a guided portion, which is slidably connected to the guide portion in the first direction so that the support base can move relative to the mounting base in the first direction. The lever is rotatably connected to the support base. The part of the support base rotatably connected to the lever serves as a fulcrum. The part of the lever located on one side of the fulcrum along its length is the power arm, and the part located on the other side of the fulcrum is the resistance arm. The lifting member is located on the power arm, and the clamping member is fixedly connected to the resistance arm. The lifting member can drive the power arm to move in a direction away from the mounting base in a second direction, while simultaneously pressing one end face of the clamping member along its extension direction against the top surface of the conductor in the winding mold. This clamping fixture can adapt to conductors of different specifications by adjusting the position of the lever, thus solving the problem of poor versatility of existing clamping fixtures.

[0049] 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.

[0050] Example 1:

[0051] This embodiment 1 provides an axial clamping fixture for a stellarator coil winding mold, which is used to clamp the conductor in the winding mold.

[0052] Specifically, such as Figures 1 to 3 As shown, the axial clamping fixture for the stellarator coil winding mold includes: a mounting base 100, a support base 200, a lever 300, a lifting component 400, and a clamping component 500.

[0053] Regarding the mounting base 100, the mounting base 100 is used to support the lever 300 and the support base 200. The mounting base 100 is fixedly mounted on the winding mold 800. The mounting base 100 is provided with a guide portion 110 extending along the first direction X.

[0054] It should be noted that the mounting base 100 can be made of thickened steel plate welded together. This design provides high rigidity, minimizes deformation during the clamping process, and ensures stable output of clamping force.

[0055] Regarding the support base 200, the support base 200 is used to support the lever 300 and provide it with a fulcrum 220. The support base 200 is provided with a guided part 210, which is slidably connected to the guide part 110 along the first direction X, so that the support base 200 can move relative to the mounting base 100 along the first direction X. When the guided part 210 of the support base 200 moves on the guide part 110 of the mounting base 100, the support base 200 can drive the lever 300 to move along the first direction X, so that the clamping member 500 of the lever 300 can also move along the first direction X. When using the clamping fixture, the position to be clamped can be determined according to the current position and specific structure of the conductor 700, and then the clamping member 500 of the lever 300 can be moved to that position. This setting allows the clamping fixture to be adapted to the structure and position of various conductors 700, avoiding frequent changes of the clamping fixture due to different conductor structures during the clamping of the conductor 700, thus avoiding wasting processing time.

[0056] It should be noted that the specific structure of the guide part 110 and the guided part 210 is not limited. For example, it can be a slide and a slider, a guide rail and a moving part, or a ball screw and a slider. The guide rail and the ball screw are standard parts. Suitable guide rails, ball screws and moving parts that cooperate with them can be purchased according to the size of the mounting base 100. This embodiment does not make further limitations here.

[0057] Regarding lever 300, lever 300 is used to transmit clamping force to clamping member 500. Lever 300 extends in the first direction X and is rotatably connected to support base 200. The part of support base 200 rotatably connected to lever 300 serves as fulcrum 220. The part of lever 300 located on one side of fulcrum 220 along its length is power arm 310, and the part located on the other side of fulcrum 220 is resistance arm 320.

[0058] Regarding the lifting component 400 and the clamping component 500, such as Figures 1 to 3 As shown, the lifting member 400 is disposed on the power arm 310, and the lifting member 400 is used to drive the power arm 310 of the lever 300 to move. The clamping member 500 is fixedly connected to the resistance arm 320, and the clamping member 500 is used to clamp the conductor 700 and extends in the second direction Y, which is perpendicular to the first direction X. The lifting member 400 can drive the power arm 310 to move away from the mounting base 100 in the second direction Y, while simultaneously moving the resistance arm 320 and the clamping member 500 toward the support base 200 in the second direction Y. One end face of the clamping member 500 along its extension direction is pressed against the winding mold 800 (see...). Figure 3 The top surface of the conductor 700 inside the clamping member 500 and the top surface of the conductor 700 are in static friction contact. This setting can convert the lifting force provided by the lifting member 400 to the power arm 310 of the lever 300 into the clamping force provided by the clamping member 500 on the resistance arm 320 to the conductor 700 through the fulcrum 220. The position of the fulcrum 220 relative to the two ends of the lever 300 can be set according to actual needs, thereby adjusting the magnitude of the clamping force and ensuring that the clamping fixture can provide sufficient clamping force to the conductor 700.

[0059] It should be noted that the specific structure and setting of the lifting component 400 are not limited. For example, it can be a bolt, which lifts the power arm 310 of the lever 300 by turning the bolt; it can also be a cylinder, which lifts the power arm 310 of the lever 300 by the piston rod of the cylinder; or it can be a jack. This embodiment does not make further limitations here. The specific structure and setting of the clamping component 500 are not limited. For example, it can be a non-metallic component or a metal material with good ductility. This setting can better protect the conductor 700 from being crushed. This embodiment does not make further limitations here.

[0060] It should be further noted that the fixing connection method of the clamping member 500 and the resistance arm 320 is not limited. For example, it can be a welding connection, a bolt fastening, or a snap-fit ​​connection. This embodiment does not make any further limitations here.

[0061] In this application, an axial clamping fixture for a stellarator coil winding mold is provided based on the above embodiments, such as... Figure 2 As shown, the guide portion 110 is a guide groove, and the guided portion 210 is a protrusion. The outer sidewall of the protrusion is slidably connected to the inner sidewall of the guide groove, and can limit the support 200 to move only relative to the mounting base 100 along the first direction X. The protrusion can slide to a suitable position along the extension direction of the guide groove as needed. While taking into account mutual sliding, the outer sidewall of the protrusion and the inner sidewall of the guide groove cooperate to limit the relative position of the protrusion and the guide groove in the direction perpendicular to the guide groove wall and in the second direction Y to remain unchanged, thereby ensuring that the support 200 moves only relative to the mounting base 100 along the first direction X. This setting can ensure that when the lever 300 is under force, the support 200 will not move in other directions due to the force, ensuring the stability of the position of the lever 300 during the clamping process, thereby enabling the clamping fixture to provide a stable clamping force to the conductor 700.

[0062] In addition, this sliding connection structure, in which the protrusion and guide groove cooperate, is simple in design, easy to manufacture, and has a low processing cost.

[0063] In this application, an axial clamping fixture for a stellarator coil winding mold is provided based on the above embodiments, such as... Figures 1 to 2 As shown, the mounting base 100 has a groove-shaped structure 120 extending along the second direction Y in a portion of the first direction X. The clamping member 500 passes through the groove-shaped structure 120 along the second direction Y to clamp the top surface of the conductor 700. Guide grooves are formed on both sides of the groove-shaped structure 120 along its width direction. This arrangement allows the clamping fixture to adapt to the conductor 700 whose clamping position is directly below the groove-shaped structure 120. When the conductor 700 is directly below the groove-shaped structure 120, the clamping member 500 can... The guide groove is set on both sides of the groove wall of the groove structure 120 along its width direction, so that the guided part 210 of the support 200 can move inside the groove structure 120. This ensures that the clamping member 500 of the lever 300 can clamp the conductor 700 directly below the groove structure 120 and also clamp the conductor 700 on the side of the mounting base 100 facing the clamping member 500, so that the clamping fixture can have greater versatility.

[0064] In addition, the guide groove extends through the width of the groove structure 120. The sidewall of the guide groove and the outer sidewall of the protrusion cooperate to limit the relative position of the protrusion and the guide groove in the second direction Y to remain unchanged, so that the support 200 will not move in the second direction Y during the sliding process, thereby ensuring that the support 200 can have good operating stability.

[0065] In this application, based on the above-described embodiment, an axial clamping fixture for a stellarator coil winding mold is provided. The lifting member 400 is a fastener. The fastener passes through the lever 300 along the second direction Y and is fixedly connected to the mounting base 100. The fastener is threadedly connected to the lever 300, and one end face of the fastener along its extension direction abuts against the mounting base 100. The distance between the fastener and the fulcrum 220 is greater than the distance between the clamping member 500 and the fulcrum 220. The one end face of the fastener along its extension direction abuts against the mounting base 100, so that the position of the fastener along its extension direction remains unchanged during the process of tightening the fastener. The fastener and the lever 300 are threadedly connected. During the rotation, the thread of the fastener engages with the thread of the lever 300 and drives the lever 300 to move along the extension direction of the fastener. This lifting structure only requires machining a threaded hole on the lever 300. The structure design is simple and the manufacturing difficulty is low. During operation, the fastener can be rotated in a certain direction, and the operation steps are simple.

[0066] It should be noted that the structure of the fastener is not limited. For example, it can be a bolt, a screw, or a stud. This embodiment does not make any further limitations.

[0067] In addition, the distance between the fastener and the fulcrum 220 is greater than the distance between the clamping member 500 and the fulcrum 220. This means that when the lifting force provided by the fastener to the lever 300 is transmitted to the clamping member 500 through the lever 300, it will be amplified. When the clamping fixture requires a larger clamping force, the position of the fulcrum 220 can be changed to amplify the clamping force. This setting enables the clamping fixture to have a better clamping effect and can adapt to working conditions that require a larger clamping force, thus having good versatility.

[0068] In this application, an axial clamping fixture for a stellarator coil winding mold is provided based on the above embodiments. The fastener is a bolt, which is a commonly used standard part with a mature manufacturing process. It can ensure good rigidity while also taking into account durability. Moreover, it is easy to purchase and has a low cost of use.

[0069] Based on the above structure, multiple fasteners can be set, with the multiple fasteners spaced apart along the length of the lever 300; alternatively, only this structure can be set.

[0070] It should be noted that the specific number of fasteners is not limited. For example, there can be 2, 3 or 4 fasteners. The specific number can be selected according to actual needs. When multiple fasteners are used at the same time, they can provide a large lifting force for the lever 300, thereby giving the clamping part 500 a high clamping force. When one fastener is subjected to a large force, the other fasteners can simultaneously press against the mounting base 100 to ensure that the fastener will not shift due to the force.

[0071] In addition, the multiple fasteners are spaced apart along the length of the lever 300 so that the fasteners can be adapted to multiple clamping positions of the clamping member 500 of the lever 300. When the clamping member 500 of the lever 300 is far from the mounting base 100, the fasteners that are far from the clamping member 500 can be used. When the clamping member 500 of the lever 300 is in the groove structure 120 area of ​​the mounting base 100, the fasteners that are close to the clamping member 500 can be used. This arrangement makes the clamping fixture more versatile.

[0072] In this application, based on the stellarator coil winding mold axial clamping fixture provided by the above embodiments, the cross-sectional area of ​​the end of the clamping member 500 facing the conductor 700 is larger than the cross-sectional area of ​​the portion of the clamping member 500 that penetrates the resistance arm 320. Setting the cross-sectional area of ​​the end of the clamping member 500 facing the conductor 700 to be larger makes the contact area between the clamping member 500 and the conductor 700 larger, thereby enabling the conductor 700 to be subjected to uniform force during the clamping process, avoiding the clamping member 500 from damaging the conductor 700, and thus making the clamping fixture have a better clamping effect.

[0073] In this application, based on the above-described embodiment, an axial clamping fixture for a stellarator coil winding mold is provided. The support base 200 is provided with a groove 230. The opening of the groove 230 faces away from the mounting base 100 in the second direction Y. The groove 230 is provided through the first direction X. The fulcrum 220 is a connecting shaft. The connecting shaft passes through and connects to the two side walls of the groove 230. The lever 300 can rotate relative to the support base 200 around the axis of the connecting shaft and is engaged between the two side walls of the groove 230. The groove 230 of the support base 200 can limit the movement of the lever 300 in the direction perpendicular to the groove wall of the groove 230, so that the lever 300 will not shake due to force when rotating around the connecting shaft, thereby ensuring the stable operation of the lever 300 and enabling the clamping fixture to provide a stable clamping force.

[0074] In this application, an axial clamping fixture for a stellarator coil winding mold is provided based on the above embodiments, such as... Figures 1 to 3As shown, the axial clamping fixture also includes an adjusting rod 600, which extends along the second direction Y. One end of the adjusting rod 600 is disposed on and fixed relative to the mounting base 100. The adjusting rod 600 is provided with a plurality of mounting portions 610 spaced apart along the second direction Y. The specific number of mounting portions 610 is not limited, for example, there can be 2, 3 or 4. The specific number can be selected according to actual needs. Some of the mounting portions 610 are fixedly connected to the winding mold 800. During the use of the clamping fixture, according to the required clamping height of the conductor 700, a more suitable mounting portion 610 on the adjusting rod 600 can be fixedly connected to the winding mold 800. This arrangement allows the clamping fixture to adapt to conductors 700 of different heights, thus having better versatility.

[0075] It should be noted that the setting method of the connecting shaft is not limited. For example, the connecting shaft can be fixed relative to the support base 200, and the connecting shaft can rotate relative to the support base 200 around the axis of the connecting shaft, thereby driving the lever 300 to rotate. Alternatively, the connecting shaft can be rotatably set relative to the support base 200, with the connecting shaft and the support base 200 being relatively fixed. The lever 300 is provided with a through hole that cooperates with the connecting shaft, so that the lever 300 rotates relative to the support base 200 around the axis of the connecting shaft. This embodiment does not impose further limitations here.

[0076] In this application, based on the stellarator coil winding mold axial clamping fixture provided by the above embodiments, the adjusting rod 600 is set as a hollow component, and the mounting part 610 is a mounting hole that penetrates the hollow component in the radial direction. The hollow structure of the adjusting rod 600 can significantly reduce the weight of the adjusting rod 600 while ensuring sufficient rigidity. This setting makes it more convenient for operators to adjust the position of the clamping fixture and reduce the labor intensity of operators. In addition, setting the mounting part 610 as a through mounting hole structure is simple in design and has low manufacturing difficulty.

[0077] Example 2:

[0078] This embodiment 2 also provides a stellarator coil winding device, such as Figure 3 As shown, the device includes a winding mold 800 and multiple stellarator coil winding mold axial clamping fixtures as described in Embodiment 1. The multiple clamping fixtures are spaced apart circumferentially along the winding mold 800. The first direction X of the clamping fixtures is parallel to the radial direction of the winding mold 800, and the second direction Y is parallel to the axial direction of the winding mold 800. A conductor 700 is provided inside the winding mold 800. The clamping fixtures can clamp the conductor 700 axially along the circumference of the winding mold 800. The spaced arrangement of the clamping fixtures allows the conductor 700 to receive relatively uniform pressure, avoiding excessive local stress on the conductor 700 and causing damage to the conductor 700.
