Description

Technical Field

[0001] This utility model relates to the field of winding tooling technology, and in particular to a structure for a high-temperature superconducting winding tooling. Background Technology

[0002] High-temperature superconducting coils are electromagnetic coils that can enter the superconducting state in a specific temperature range (such as the liquid nitrogen temperature range, 77K and above). The core component of a high-temperature superconducting coil is formed by winding high-temperature superconducting tape on a coil frame. High-temperature superconducting coils have excellent characteristics such as zero resistance, high current carrying capacity, strong magnetic field, and low-cost cooling, and are widely used in fields such as nuclear fusion equipment, energy and power equipment, and superconducting magnetic levitation devices.

[0003] The uniformity of the high-temperature superconducting tape wound on the coil frame will affect the superconducting performance and magnetic field uniformity of the high-temperature superconducting coil. Therefore, ensuring that the high-temperature superconducting tape is wound uniformly on the coil frame is a key factor in ensuring the stable performance of the high-temperature superconducting coil.

[0004] In the existing technology, the winding of high-temperature superconducting coils is carried out by manually aligning the geometric center of the coil skeleton with the rotation center of the winding platform, and fixing the coil skeleton on the winding platform so that the coil skeleton rotates synchronously with the winding platform for winding. However, manual operation inevitably has problems such as visual judgment deviation and inaccurate force control, which will cause the geometric center of the skeleton to deviate from the rotation center of the winding platform. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the geometric center of the bobbin and the rotation center of the winding platform are offset due to the manual operation of the winding of existing high-temperature superconducting coils.

[0006] To solve the above-mentioned technical problems, the present invention provides a structure for a high-temperature superconducting winding fixture. The high-temperature superconducting winding fixture includes a rotating base rotatable about a central axis, and a chuck assembly and a frame fixing assembly stacked sequentially on one side of the rotating base. The frame fixing assembly includes a support plate and at least one pair of fixing components. The support plate is fixed to a corresponding side of the rotating base and can rotate together with the rotating base about a central axis. Each pair of fixing components is radially opposite to each other on the support plate and is radially movable on the support plate. One end of the fixed component protrudes from the side of the support disk away from the rotating base along the central axis, and can switch between a fixed state abutting against the inner peripheral wall of the coil frame of the high-temperature superconducting coil and a separated state separated from the inner peripheral wall; and the chuck assembly includes a centering chuck and at least a pair of driving components, wherein the centering chuck is coaxially disposed between the support disk and the rotating base and can rotate relative to the rotating base about the central axis; wherein each driving component is disposed on the centering chuck, is drively connected to a corresponding fixed component and can drive the fixed component to switch between a fixed state and a separated state.

[0007] In the above technical solution, the central axis is the rotation center of the entire high-temperature superconducting winding fixture. The central axis also serves as the geometric center during the winding of the high-temperature superconducting coil. That is, before winding, the geometric center of the coil frame needs to be aligned with the central axis to ensure precise and uniform winding. In the high-temperature superconducting winding fixture, the rotating base, support plate, and centering chuck are coaxially arranged and can rotate around the central axis. The support plate is used to hold the high-temperature superconducting coil. Each fixing component protrudes from one end of the support plate on the side opposite to the rotating base, abutting against the inner circumferential wall of the coil frame to fix the high-temperature superconducting coil. Each fixing component is driven to move radially along the support plate by a drive component connected to it, causing each fixing component to abut or separate from the inner circumferential wall of the coil frame. By arranging each pair of fixed components radially opposite to each other on the support plate, and connecting the driving component to each fixed component through transmission, when each group of driving components moves synchronously on the centering chuck, it drives each group of fixed components to move synchronously radially on the support plate. This automatically aligns the geometric center of the coil bobbin with the central axis, and simultaneously fixes the coil bobbin on the support plate to complete the centering. In the above scheme, because each group of driving components and each group of fixed components moves synchronously, the centering accuracy is significantly improved compared to the manual alignment method, and the problem of the geometric center of the coil bobbin being offset from the rotation center of the entire high-temperature superconducting winding fixture will not occur.

[0008] Furthermore, the purpose of setting at least one pair of fixing components is to adapt to high-temperature superconducting coils of different shapes and improve the versatility of high-temperature superconducting winding fixtures. That is, the number of fixing components can be increased or decreased according to the specific shape of the high-temperature superconducting coil. For example, when the high-temperature superconducting coil is racetrack-shaped, a pair of fixing components are set and each fixing component abuts against the two ends with the longer radial dimension of the racetrack-shaped high-temperature superconducting coil. When the high-temperature superconducting coil is circular, two pairs of fixing components are set and each fixing component abuts against the inner circumferential wall of the coil frame of the circular high-temperature superconducting coil evenly along the circumference of the high-temperature superconducting coil.

[0009] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in this embodiment includes at least one pair of guide grooves on the surface of the support disk. Each guide groove extends radially along the support disk, and the other end of each fixing component extends axially toward the rotating base and extends to the other side of the support disk, slidingly disposed within a corresponding guide groove. Furthermore, each pair of guide grooves extends symmetrically on the support disk relative to the central axis. Each driving component includes at least one pair of guide grooves on a centering chuck, and a driving slider disposed within each guide groove and movable along the guide groove. Each guide groove extends radially inclined relative to the centering chuck, and the end of each driving slider near the support disk is fixedly connected to the other end of a corresponding fixing component. Each pair of guide grooves extends symmetrically on the centering chuck relative to the central axis. Each pair of guide grooves and the corresponding pair of guide grooves are axially aligned. The centering chuck can rotate relative to the support disk around the central axis, driving each driving slider to move within the guide groove and linking the fixing components to switch between a fixed state and a separated state along the corresponding guide groove.

[0010] The core of aligning the geometric center of the coil frame with the central axis is achieved by extending each pair of guide slots symmetrically on the centering chuck relative to the central axis. Specifically, when the centering chuck rotates around the central axis relative to the support plate, the drive sliders in each pair of guide slots move radially and synchronously relative to the centering chuck within the guide slots. Since each drive slider is fixedly connected to a corresponding fixed component, and the radial extension of the guide slots along the support plate restricts each pair of fixed components to move radially and synchronously along the support plate under the drive of each pair of drive sliders, the coil frame can be fixed on the support plate and the geometric center of the coil frame can be aligned with the central axis after each pair of fixed components switches from a separated state to a fixed state.

[0011] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in this embodiment is such that each guide groove is an arc-shaped groove formed on the centering chuck, and the arc-shaped groove extends obliquely relative to the circumference of the centering chuck; each pair of arc-shaped grooves extends symmetrically on the centering chuck relative to the central axis, and the oblique direction of the plurality of arc-shaped grooves relative to the circumference of the centering chuck is consistent; wherein the central angle occupied by each arc-shaped groove on the centering chuck satisfies: .in: n is the central angle occupied by each arc groove on the centering chuck; n is the number of guide grooves opened on the centering chuck.

[0012] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in the embodiment of the present invention is such that the ends of two adjacent arc-shaped grooves are aligned with each other in the radial direction of the centering chuck and are spaced apart; and at least one pair of guide grooves are evenly spaced apart in the circumferential direction of the support plate.

[0013] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in this embodiment includes a rotating base comprising a chassis, wherein a connecting boss protruding axially toward a support plate is provided on the circumferential edge of the chassis, the connecting boss extending circumferentially along the chassis; the circumferential edge of the support plate overlaps and is fixedly connected to the connecting boss by a connector, and there is a receiving space between the support plate and the chassis, wherein a centering chuck is rotatably disposed in the receiving space around the central axis.

[0014] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in this embodiment includes a groove extending circumferentially along the chassis between the two ends of the connecting boss, and a stop block slidably disposed within the groove; and a rotating part protruding from the edge of the centering chuck, the rotating part protruding from the groove beyond the edge of the support plate and the chassis; wherein when the fixing component is in a separated state, the rotating part drives the centering chuck to rotate around the central axis along a first rotation direction, and moves the fixing component to a fixed state abutting against the coil frame; and, in the fixed state, the stop block abuts against one side of the rotating part in a second rotation direction, fixed relative to the groove, preventing the rotating part from driving the centering chuck to rotate along the second rotation direction; wherein the first rotation direction and the second rotation direction are rotation directions opposite to each other around the central axis.

[0015] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in the embodiment of the present invention includes a slide rod extending along the extension direction of the guide groove. A fixing block protruding from one side of the support plate is provided at one end of the slide rod near the central axis, and a fastener facing the centering chuck is provided at the other end. Each fastener is fixed to a corresponding drive slider. Furthermore, when the fixing component is in a fixed state, the side of each fixing block away from the central axis abuts against the inner peripheral wall of the coil frame.

[0016] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in the embodiment of the present invention is provided with at least one pair of adjusting components on each fixed block; wherein each adjusting component includes a threaded hole that penetrates the fixed block radially, and an adjusting bolt that passes through the corresponding threaded hole and is threadedly connected to the fixed block, and the end of each adjusting bolt near the coil frame is adjustablely abutting against the inner peripheral wall of the coil frame.

[0017] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in this embodiment of the present invention has at least two layers of high-temperature superconducting tape wound along the axial direction of the coil skeleton. The high-temperature superconducting winding fixture also includes a temporary winding disc support seat, which is fixedly supported above the support disc by a connecting rod; the temporary winding disc with the high-temperature superconducting tape wound is supported on the temporary winding disc support seat.

[0018] According to another specific embodiment of the present invention, the structure of the high-temperature superconducting winding fixture disclosed in the embodiment of the present invention further includes a rotary drive assembly. The rotary drive assembly includes a rotating shaft that passes through a rotating base and a chuck assembly in sequence along the central axis, and the rotating shaft is fixedly connected to a support disk.

[0019] The beneficial technical effects of this utility model are as follows: The structure of the high-temperature superconducting winding fixture provided by this utility model includes a rotating base that can rotate around a central axis, and a chuck assembly and a skeleton fixing assembly stacked sequentially on one side of the rotating base. The high-temperature superconducting coil is placed on the support plate of the skeleton fixing assembly. Each fixing component protrudes from one end of the support plate on the side of the support plate away from the rotating base to abut against the inner peripheral wall of the coil skeleton that fixes the high-temperature superconducting coil. Each fixing component is driven to move radially along the support plate by a drive component that is connected to it. Because each set of drive components and each set of fixing components move synchronously, the centering accuracy is significantly improved compared to manual alignment, and the problem of the geometric center of the coil skeleton being offset from the rotation center of the entire high-temperature superconducting winding fixture will not occur. The purpose of setting at least one pair of fixing components is to adapt to high-temperature superconducting coils of different shapes and improve the versatility of the high-temperature superconducting winding fixture.

[0040] 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.

[0041] This invention provides a structure for a high-temperature superconducting winding fixture. The high-temperature superconducting winding fixture includes a rotating base, a chuck assembly, and a frame fixing assembly. At least one pair of fixing components in the frame fixing assembly are respectively connected to at least one set of driving components in the chuck assembly. When each set of driving components moves synchronously on the centering chuck, it drives each set of fixing components to move synchronously radially on the support plate, and can move to a state where it abuts against the inner peripheral wall of the coil frame of the high-temperature superconducting coil, thereby automatically aligning the geometric center of the coil frame with the central axis, fixing the coil frame on the support plate, and completing centering at the same time. This invention also increases or decreases the number of fixing components according to the specific shape of the high-temperature superconducting coil to adapt to high-temperature superconducting coils of different shapes, improving the versatility of the high-temperature superconducting winding fixture.

[0042] like Figure 1 , Figure 3 and Figure 5 As shown, in one specific embodiment of this utility model, the structure of the high-temperature superconducting winding fixture includes a rotating base 1, and a chuck assembly 2 and a skeleton fixing assembly 3 stacked sequentially on one side of the rotating base 1. The skeleton fixing assembly 3 includes a support plate 30 and at least one pair of fixing components 31. The chuck assembly 2 includes a centering chuck 20 and at least one pair of driving components 21. The rotating base 1, support plate 30, and centering chuck 20 are coaxially arranged and can rotate around a central axis (see...). Figure 1The three components (dashed lines in the figure) rotate synchronously. The central axis is the rotation center of the entire high-temperature superconducting winding fixture. They can all rotate around the central axis via a rotary drive assembly (such as the rotating shaft of a motor). The winding action occurs when all three rotate synchronously. The rotary drive assembly is not shown in the attached figure, but it can be understood that it refers to the mechanism that drives the frame fixing assembly 3 and the coil frame 50 to rotate synchronously for winding. The central axis also serves as the geometric center of the high-temperature superconducting coil 5 during winding. That is, before winding, the geometric center of the coil frame 50 needs to be aligned with the central axis to ensure that the geometric center of the high-temperature superconducting coil 5 is aligned with the central axis during winding, achieving precise and uniform winding. It should be noted that the high-temperature superconducting coil 5 to be wound has an overall ring structure, mainly including the ring-shaped coil frame 50 (see details...). Figures 1-5 ) and the high-temperature superconducting tape 51 wound around the outer periphery of the coil frame 50 (see details) Figure 4 and Figure 5 ).

[0043] The present invention specifically adopts the following structure to align the geometric center of the coil frame 50 of the high-temperature superconducting coil 5 with the central axis.

[0044] like Figure 1 , Figure 3 and Figure 5 As shown, the centering chuck 20 is axially along the central axis ( Figure 1 , Figure 3 and Figure 5 The Z-direction of the support plate is located on the upper side of the rotating base 1. The support plate 30 is used to place the high-temperature superconducting coil 5. The support plate 30 is located on the upper side of the centering chuck 20 along the central axis and is fixedly connected to the rotating base 1. That is, the centering chuck 20 is located between the support plate 30 and the rotating base 1, and the high-temperature superconducting coil 5 is placed on the upper side of the support plate 30.

[0045] Specifically, such as Figure 1 , Figure 3 and Figure 5As shown, each pair of fixing components 31 is radially opposite to each other on the support disk 30, that is, two fixing components 31 in each pair are symmetrically arranged radially on the support disk 30. Each fixing component 31 is disposed on the support disk 30 and can move radially on the support disk 30. One end of each fixing component 31 protrudes from the side of the support disk 30 away from the rotating base 1 (i.e., the upper side of the support disk 30) on the axial direction of the central axis. When each fixing component 31 moves radially on the support disk 30, the end of each fixing component 31 protruding from the upper side of the support disk 30 moves radially on the support disk 30. That is, each fixing component 31 can move towards the direction closer to the central axis or towards the direction away from the central axis. Before the fixing components 31 start moving, the coil frame 50 of the high-temperature superconducting coil 5 is placed on the support disk 30, and each fixing component 31... The end protruding from the support plate 30 is located on the inner circumference of the coil frame 50. After the fixing component 31 starts to move, this end can switch between a fixed state that abuts against the inner circumferential wall of the coil frame 50 of the high-temperature superconducting coil 5 and a separated state that is separated from the inner circumferential wall. The fixed state refers to the state in which the end of the fixing component 31 protruding from the support plate 30 abuts against the inner circumferential wall of the coil frame 50, so that the coil frame 50 is fixed on the support plate 30. After reaching the fixed state, it means that the coil frame 50 has been fixed and its geometric center has been aligned with the central axis, and the winding operation can be performed. The separated state refers to the state in which the end of the fixing component 31 protruding from the support plate 30 is separated from the inner circumferential wall of the coil frame 50. The coil frame 50 is in the separated state when it is first placed on the support plate 30 and has not been fixed yet, and when the high-temperature superconducting coil 5 is ready to be removed from the support plate 30 after the winding is completed. As each pair of fixing components 31 moves radially away from the central axis, the fixing components 31 protrude from the end of the support disk 30 and move closer to the inner peripheral wall of the coil frame 50, thus switching from a separated state to a fixed state. The purpose of arranging the fixing components 31 in pairs radially on the support disk 30 is to ensure that each pair of fixing components 31 can abut against both ends of the coil frame 50 radially. When the coil frame 50 is as follows... Figure 2 When the coil is circular as shown, the radial direction of the coil frame 50 is its diameter. Figure 4 When the loop shape or elliptical loop is shown, the radial direction of the coil frame 50 refers to the line connecting the two ends that pass through its geometric center and are furthest apart (such as the major axis of an ellipse).

[0046] It should be noted that the fixing component 31 can be connected to the support plate 30 through a sliding groove structure. For example, a radially extending strip groove can be formed on the support plate 30, and one end of the fixing component 31 can be slidably disposed in the strip groove. Alternatively, a radially extending strip protrusion can be formed on the support plate 30, and a groove that matches the strip protrusion can be provided at one end of the fixing component 31, allowing the fixing component 31 to move radially. The fixing component 31 can be a block-shaped structure or a rod-shaped structure extending axially, or it can be an overall L-shaped structure, with one end extending axially parallel to the central axis and protruding from one side of the support plate 30, and the other end extending radially parallel to the support plate 30 and slidably connected to the support plate 30. As long as the fixing component 31 can move radially along the support plate 30 and the end protruding from the support plate 30 can abut against the inner peripheral wall of the coil frame 50, it is acceptable.

[0047] like Figure 1 As shown, each fixed component 31 is driven to move radially along the support disk 30 by a drive component 21 connected to it in a transmission manner, thereby driving the fixed component 31 to switch between a fixed state and a separated state. Each drive component 21 is disposed on the centering chuck 20, and the number of drive components 21 corresponds to the number of fixed components 31. For example, if there is a pair of fixed components 31, there is a pair of drive components 21; if there are two pairs of fixed components 31, there are two pairs of drive components 21. Each driving component 21 moves synchronously on the centering chuck 20, driving each set of fixed components 31 to move synchronously radially on the support plate 30. Therefore, the distance of each fixed component 31 from the central axis is always equal when it moves, and each fixed component 31 exerts a force on the inner peripheral wall of the coil frame 50 when it moves away from the central axis. By utilizing the characteristic that the distance of each fixed component 31 from the central axis is always equal, the geometric center of the coil frame 50 is automatically aligned with the central axis, and the centering is completed while fixing the coil frame 50 on the support plate 30. The structure in which each driving component 21 moves synchronously and drives each fixed component 31 to move synchronously makes the centering accuracy significantly improved compared with the manual alignment method, and there will be no problem of the geometric center of the coil frame 50 being offset from the rotation center of the entire high-temperature superconducting winding fixture.

[0048] It should be noted that the driving component 21 can specifically be a motor, which is positioned between the support plate 30 and the centering chuck 20, with the motor output shaft extending radially along the centering chuck 20. By connecting the fixed component 31 to the motor output shaft on the side closest to the motor, the rotational motion of the motor output shaft can be converted into linear movement of the fixed component 31 along the radial direction of the support plate 30. Synchronous movement of the driving component 21 can be achieved by controlling the synchronous operation of each motor, thereby enabling the fixed component 31 to drive the coil frame 50 to achieve centering. 21 can also be a slider fixedly connected to each fixed component 31. At least one pair of slide grooves 101 are opened on the centering chuck 20, extending outward from the center of the centering chuck 20 and symmetrical with respect to the central axis. The slider is respectively set in each slide groove 101. By rotating the centering chuck 20, the slider moves in the slide groove 101 by the force exerted on the slider by the slide groove 101 of the centering chuck 20, thereby moving the fixed component 31 in conjunction. The self-centering characteristic of the centering chuck 20 when it rotates is used to achieve the purpose of centering the fixed component 31 driving the coil frame 50.

[0049] Furthermore, the purpose of providing at least one pair of fixing components 31 is to adapt to high-temperature superconducting coils 5 of different shapes, thereby improving the versatility of the high-temperature superconducting winding fixture. The number of fixing components 31 can be increased or decreased according to the specific shape of the high-temperature superconducting coil 5, for example... Figures 1-3 As shown, the high-temperature superconducting coil 5 to be wound is circular (where the coil frame 50 is as shown in the figure). Figure 2 As shown, two pairs of fixing components 31 are provided, such that each fixing component 31 uniformly abuts against the inner peripheral wall of the coil frame 50 of the circular high-temperature superconducting coil 5 along the circumference of the coil 5; for example... Figures 4-5 As shown, when the wound high-temperature superconducting coil 5 is in the shape of a racetrack (e.g.) Figure 4 As shown, the coil frame 50 is racetrack-shaped, and a high-temperature superconducting tape 51 has been wound around its outer periphery. The high-temperature superconducting tape 51 is fixed to the coil frame 50 by tape fixing members 52. A pair of fixing members 31 are provided, with each fixing member 31 abutting against the two ends of the longer radial dimension of the racetrack-shaped high-temperature superconducting coil 5. It should be noted that when the winding fixture needs to... Figure 3 The example shown is used to convert the coil 5 into a circular high-temperature superconducting coil. Figure 5 When the runway-shaped high-temperature superconducting coil 5 is wound as shown, only one pair of fixing components 31 needs to be removed. It should be noted that when the high-temperature superconducting coil 5 is circular, the number of fixing components 31 can be two pairs, three pairs, or other numbers; in this embodiment, two pairs are preferred.

[0050] In one specific embodiment of this utility model, the high-temperature superconducting winding fixture further includes a rotary drive assembly (not shown in the figure). The rotary drive assembly is used to drive the rotating base 1, the chuck assembly 2, and the skeleton fixing assembly 3 to drive the coil skeleton 50 fixed on the support plate 30 to rotate synchronously around the central axis for winding. The rotary drive assembly includes a rotating shaft whose axis coincides with the central axis. The rotating shaft can be the output shaft of a motor or a rotating shaft that is connected to the output shaft of a motor. One end of the rotating shaft passes through the rotating base 1 and the chuck assembly 2 along the central axis and is fixedly connected to the middle of the support plate 30 (for example, a connecting hole is opened in the middle of the support plate 30, and a fastener 312 passes through the connecting hole and is fixed to the end of the rotating shaft). When the rotating shaft rotates around the central axis, it drives the support plate 30 to rotate, thereby driving the coil skeleton 50 fixed on the support plate 30 to rotate.

[0051] In one specific embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 5 As shown, at least one pair of guide grooves 300 are formed on the surface of the support disk 30. Each pair of guide grooves 300 extends symmetrically on the support disk 30 with respect to the central axis, that is, each pair of guide grooves 300 is symmetrically arranged radially along the support disk 30. Each guide groove 300 extends radially along the support disk 30. The other end of each fixing component 31 that does not abut against the inner peripheral wall of the coil frame 50 is slidably disposed in a corresponding guide groove 300 and extends axially toward the rotating base 1 to the other side of the support disk 30 for connection with the drive component 21. The guide grooves 300 are used to limit the fixing component 31. That is, the way the guide grooves 300 extend radially along the support disk 30 restricts the fixing component 31 to move only radially along the support disk 30.

[0052] like Figure 1 and Figure 6As shown, each drive component 21 includes at least one pair of guide grooves 210 formed on the centering chuck 20. Each pair of guide grooves 210 extends symmetrically on the centering chuck 20 with respect to the central axis. Each pair of guide grooves 300 is arranged symmetrically along the radial direction of the support plate 30 or symmetrically around the central axis. Each pair of guide grooves 210 and the corresponding pair of guide grooves 300 are arranged axially. Each guide groove 210 extends radially inclined with respect to the centering chuck 20, that is, each guide groove 210 extends from a position close to the center of the centering chuck 20 toward the edge of the centering chuck 20, and the two ends of the extension direction of each guide groove 210 form an angle with the line connecting the center of the centering chuck 20. The guide groove 210 can be a straight groove or an arc groove. The driving component 21 also includes at least one pair of driving sliders 211, which are respectively disposed in a corresponding guide groove 210. The end of each driving slider 211 near the support plate 30 is fixedly connected to the other end of a corresponding fixing component 31. The centering chuck 20 can rotate relative to the support plate 30 around the central axis, driving each driving slider 211 to move in the guide groove 210, and linking the fixing component 31 to move along the corresponding guide groove 300, thereby realizing the switching between the fixed state and the separated state. In the above structure, the symmetrical extension of each pair of guide grooves 210 relative to the central axis on the centering chuck 20 is the core of aligning the geometric center of the coil frame 50 with the central axis. Specifically, when the centering chuck 20 rotates relative to the support plate 30 around the central axis, the drive slider 211 is acted upon by the guide grooves 210 and moves radially inclined relative to the centering chuck 20 within the guide grooves 210. Since the rotation of one centering chuck 20 drives the movement of multiple drive sliders 211, the multiple drive sliders 211 move synchronously, that is, the distance between each drive slider 211 and the center of the centering chuck 20 is always the same. Furthermore, since each drive slider 211 is fixedly connected to the corresponding fixing component 31, the synchronous movement of each drive slider 211 is linked to the synchronous movement of each fixing component 31. When each pair of fixing components 31 switches from the separated state to the fixed state, the coil frame 50 can be fixed on the support plate 30, ensuring that the geometric center of the coil frame 50 is aligned with the central axis.

[0053] It should be noted that at least one pair of guide grooves 300 can be one pair, two pairs, or other quantities. In this specific embodiment, two pairs are preferred. When the high-temperature superconducting coil 5 is annular, a fixing component 31 is provided in both pairs of guide grooves 300. When the high-temperature superconducting coil 5 is racetrack-shaped, a fixing component 31 can be provided in one pair of guide grooves 300. The number of at least one pair of guide grooves 210 can be one pair, two pairs, or other quantities. In this specific embodiment, two pairs are preferred. When the high-temperature superconducting coil 5 is annular, a driving slider 211 is provided in both pairs of guide grooves 210. When the high-temperature superconducting coil 5 is racetrack-shaped, a driving slider 211 can be provided in one pair of guide grooves 210.

[0054] like Figure 1 , Figure 3 and Figure 5 As shown, the drive slider 211 can slide within the guide groove 210, and the fixing component 31 can slide radially within the guide groove 300. The drive slider 211 is used to install the fixing component 31. After it is fixed, the rotating part 200 on the centering chuck 20 (for example, a push rod structure) is manually pushed to rotate the centering chuck 20, thereby driving the fixing component 31 to clamp the coil frame 50. The high-temperature superconducting winding fixture provided by this utility model can be adapted to fix coil frames 50 of different sizes and shapes, and automatically center the coil frame 50 while tightening it.

[0055] In one specific embodiment of this utility model, such as Figure 1 and Figure 6 As shown, each guide groove 210 is an arc-shaped groove formed on the centering chuck 20. The arc-shaped groove extends obliquely relative to the circumference of the centering chuck 20, that is, one end of the arc-shaped groove is close to the center of the centering chuck 20, and the other end is far away from the center of the centering chuck 20. Furthermore, the connection between the two ends of the arc-shaped groove and the center of the centering chuck 20 forms a certain angle, which is the central angle occupied by each arc-shaped groove on the centering chuck 20. central angle satisfy: .in: n is the central angle occupied by each arc groove on the centering chuck 20; n is the number of guide grooves 210 opened on the centering chuck 20. For example, when there are two pairs of arc grooves, n is 4, and the central angle occupied by each arc groove on the centering chuck 20 is 90°. With this arrangement, the extension range of multiple arc grooves within the disk surface of the centering chuck 20 covers the circumference of the centering chuck 20, making the movable range of the drive slider 211 within the guide groove 210 larger, and thus the movable range of the fixing component 31 within the guide groove 300 larger, so as to adapt to high-temperature superconducting coils 5 of various sizes. For example, when there is one pair of fixing components 31, this fixture can be used to fix racetrack-shaped high-temperature superconducting coils 5 of various sizes with a maximum radial distance of 140mm-500mm. When there are two pairs of fixing components 31, this fixture can be used to fix circular high-temperature superconducting coils 5 of various sizes with a diameter of 140mm-500mm.

[0056] like Figure 6 As shown, each pair of guide grooves 210 (arc grooves) is centrally symmetrical about the centering chuck 20 with respect to the central axis, and the multiple guide grooves 210 (arc grooves) are inclined in the same direction about the circumference of the centering chuck 20, for example, they all extend in a clockwise or counterclockwise direction.

[0057] Furthermore, such as Figure 6 As shown, in one specific embodiment of this utility model, the ends of two adjacent guide grooves 210 (arc grooves) are aligned with each other and spaced apart in the radial direction of the centering chuck 20. That is, the ends of two adjacent guide grooves 210 (arc grooves) that are close to each other are located in the same radial direction of the centering chuck 20, and as... Figure 1 , Figure 3 and Figure 5 As shown, at least one pair of guide grooves 300 are evenly spaced in the circumferential direction of the support disk 30.

[0058] In one specific embodiment of this utility model, such as Figure 1 As shown, the rotating base 1 includes a chassis 10, and a support plate 30 is spaced apart from the chassis 10 to form a receiving space 4. A centering chuck 20 is disposed within this receiving space 4. When the fixing component 31 needs to be switched between a separated state and a fixed state, the support plate 30 and the chassis 10 remain stationary, while the centering chuck 20 rotates relative to the support plate 30 and the chassis 10 around its central axis within the receiving space 4. This receiving space 4 isolates the centering chuck 20 from the coil frame 50, the rotary drive assembly, etc., providing an independent rotational space for the operation of the centering chuck 20. Figure 1 , Figure 3 and Figure 5As shown, the circumferential edge of the chassis 10 is provided with a connecting boss 100 protruding axially toward the support plate 30. The connecting boss 100 extends circumferentially along the chassis 10, thereby forming a receiving space 4 on the inner circumferential side of the connecting boss 100. The centering chuck 20 is adapted to be disposed on the inner circumference of the connecting boss 100. The circumferential edge of the support plate 30 overlaps and is fixedly connected to the connecting boss 100 by the connector 12, that is, the support plate 30 and the chassis 10 are fixed to each other. After the coil is fixed, the coil frame 50 is fixed to the support plate 30 by the fixing component 31 in a tightening manner. The centering chuck 20 needs to be kept stationary relative to the chassis 10 and the support plate 30 by the locking component or the blocking component. During winding, the chassis 10, the centering chuck 20, the support plate 30, the coil frame 50 and other accessories all rotate under the drive of the rotation drive assembly.

[0059] It should be noted that the connector 12 can be a clamp, which can be used to clamp the upper side of the support plate 30 and the lower side of the base plate 10 to fix the two. It can also be a buckle, with one end fixed to the connecting boss 100 and the other end snapped into the edge of the support plate 30 to fix the two. It can also be a rod-shaped fastener (such as an M10×20 bolt), which can be fixed by making corresponding threaded holes on the edge of the support plate 30 and the top surface of the connecting boss 100.

[0060] In one specific embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 5 As shown, a rotating part 200 protrudes from the edge of the centering chuck 20. The rotating part 200 protrudes from the edges of the support plate 30 and the base plate 10. The rotating part 200 can be manually operated or driven by a drive component to rotate around the central axis between the two ends of the connecting boss 100, thereby driving the centering chuck 20 to rotate. After the rotating part 200 drives the centering chuck 20 to rotate to a preset position, the rotating part 200 needs to be limited and blocked to prevent the centering chuck 20 from rotating back to the initial position. Specifically, an arc-shaped groove 101 extending circumferentially along the base plate 10 is formed between the two ends of the connecting boss 100. A stop block 11 is slidably disposed in the groove 101. The range of the central angle of the base plate 10 corresponding to the groove 101 is preferably 100°. The stop block 11 can slide in the groove 101 to block the rotating part 200. When the fixing component 31 is in the separated state, the rotating part 200 rotates along the first rotation direction ( Figure 3 and Figure 5In the first rotation direction (A direction, i.e., counterclockwise), the centering chuck 20 rotates around the central axis, and the linkage fixing component 31 moves to a fixed state abutting against the coil frame 50. That is, when the rotating part 200 rotates in the first rotation direction, it drives the centering chuck 20 to rotate in the first rotation direction, and the driving slider 211 in the guide groove 210 slides away from the center of the centering chuck 20. The driving slider 211 drives the fixing component 31 to move radially outward along the support plate 30 until it switches to the fixed state. Furthermore, in the fixed state, the stop block 11 slides in the slide groove 101 to abut against the rotating part 200 in the second rotation direction (A direction, i.e., counterclockwise). Figure 3 and Figure 5 On one side (direction B, i.e., clockwise), the stop block 11 is fixed in the slide groove 101 to prevent the rotating part 200 from driving the centering chuck 20 to rotate in the second rotation direction, thereby preventing the fixed part 31 from switching from the fixed state to the separated state; wherein the first rotation direction and the second rotation direction are rotation directions that are opposite to each other around the central axis. The stop block 11 can be fixed by locking members such as pins passing through the side wall of the slide groove 101 and the side wall of the stop block 11. In other words, by operating the rotating part 200, the centering chuck 20 rotates itself, and the drive slider 211 set in the guide groove 210 (arc groove) of the centering chuck 20 slides in the guide groove 210 (arc groove). The drive slider 211 drives the fixed part 31 fixedly connected to it to move radially along the support plate 30 to adapt to coil frames 50 of different sizes. After the centering chuck 20 rotates to the appropriate position, the centering chuck 20 is fixed relative to the base plate 10 and the support plate 30 by locking the rotating part 200 by the stop block 11. The drive slider 211 in the guide groove 210 (arc groove) and the fixed part 31 in the guide groove 300 will no longer move, so the fixed part 31 locks the coil frame 50, so that the coil frame 50 and all parts of the entire tooling rotate synchronously to perform the winding operation.

[0061] In one specific embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, each fixing component 31 includes a slide rod 310 extending along the extension direction of the guide groove 300. The slide rod 310 is disposed within the guide groove 300. A fixing block 311 protruding from one side of the support plate 30 is provided at one end of the slide rod 310 near the central axis. The fixing block 311 is the part that fixes the coil frame 50. The slide rod 310 slides within the guide groove 300 to move the fixing block 311, thereby switching between a fixed state and a separated state. When the fixing component 31 is in the fixed state, the side of each fixing block 311 away from the central axis abuts against the inner peripheral wall of the coil frame 50. A fastener 312 (e.g., an M6×20 bolt) is provided at the other end of the slide rod 310 near the outer periphery of the support plate 30. The fastener 312 is axially oriented towards the centering chuck 20. Each fastener 312 is fixed to the corresponding drive slider 211, thus fixing the slide rod 310 to the drive slider 211.

[0062] In one specific embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 As shown, each fixed block 311 is also provided with at least one pair of adjusting components 313; wherein, as shown in the figure Figure 7 and Figure 8 As shown, each adjusting component 313 includes a threaded hole 3130 that passes radially through the fixing block 311 along the support plate 30, and an adjusting bolt 3131 that passes through the corresponding threaded hole 3130 and is threadedly connected to the fixing block 311. The end of each adjusting bolt 3131 near the coil frame 50 is adjustablely abutted against the inner circumferential wall of the coil frame 50. By tightening the adjusting bolt 3131 and the threaded hole 3130, the force exerted by the adjusting bolt 3131 on the inner circumferential wall of the coil frame 50 can be adjusted, thereby fine-tuning the position of the coil frame 50 and further improving the centering accuracy of the coil frame 50. Each pair of adjusting components 313 adjusts the upper and lower ends of the inner circumferential wall of the coil frame 50 respectively to improve the adjustment accuracy. It should be noted that the adjusting bolt 3131 can specifically be an M6×10 bolt.

[0063] In one specific embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 5As shown, the high-temperature superconducting winding fixture also includes a temporary winding reel support 6. The temporary winding reel support 6 is fixedly supported above the support plate 30 by a connecting rod 7. The connecting rod 7 can pass through the bottom center of the support plate 30 along the central axis and extend upward. One end of the connecting rod 7 located at the bottom of the support plate 30 can be fixedly connected to the support plate 30 by a flange and bolts. The rotating shaft of the rotary drive assembly can be drivenly connected to the end of the connecting rod 7 located at the bottom of the support plate 30. The temporary winding reel support 6 is used to wind at least two layers of high-temperature superconducting tape (wherein... Figure 1 and Figure 3 China has not yet manufactured high-temperature superconducting tapes. Figure 5 When the high-temperature superconducting tape 51 has been wound, a temporary winding reel is temporarily placed. It should be noted that winding the high-temperature superconducting tape refers to winding the high-temperature superconducting tape on the pay-off reel (not shown in the figure) onto a coil frame 50 of a specific shape. Taking the winding of two layers of high-temperature superconducting tape as an example, when winding the high-temperature superconducting tape, the end of the high-temperature superconducting tape on the pay-off reel needs to be led to the temporary winding reel beforehand, and the length corresponding to one layer of high-temperature superconducting tape is wound on the temporary winding reel. Without disconnecting the high-temperature superconducting tape, the portion of the high-temperature superconducting tape 51 between the temporary winding reel and the pay-off reel is led to the coil frame 50 and the first layer of high-temperature superconducting tape is wound. After the first layer of high-temperature superconducting tape is wound, the temporary winding reel is removed from the temporary winding reel support 6 and placed on the pay-off reel. Then, the high-temperature superconducting tape on the temporary winding reel is wound onto the coil frame 50 to form the second layer of high-temperature superconducting tape. Figure 7 and Figure 8 The final two layers of high-temperature superconducting tape 51 wound on the coil skeleton 50 are shown.

[0064] It should be noted that when winding three layers or other quantities of high-temperature superconducting tape, the winding method is similar to the method described above, and will not be repeated here.

[0065] To facilitate understanding of the usage method of the high-temperature superconducting winding fixture provided by this utility model, the following describes the fixing process and winding process of the coil skeleton 50 of the high-temperature superconducting winding fixture, taking as an example the structure of the high-temperature superconducting winding fixture including a rotating base 1, a chuck assembly 2, and a skeleton fixing assembly 3, wherein the rotating base 1 includes a base, the driving component 21 of the chuck assembly 2 includes a guide groove 210 and a driving slider 211, and the fixing block 311 of the skeleton fixing assembly 3 is provided with an adjustment component 313.

[0066] First, the driving component 21 on the chuck assembly 2 drives the fixing component 31 of the coil frame fixing assembly 3 to move radially along the support plate 30 to a position close to the central axis. Then, the coil frame 50 is placed on the support plate 30, with each fixing component 31 positioned on the inner circumference of the coil frame 50, at which point the fixing components 31 are separated from the coil frame 50. Next, the centering chuck 20 is rotated, causing each driving component 21 to move synchronously within its guide slots 210, thereby moving each fixing component 31 radially along the support plate 30 and switching it to a fixed state. At this point, the coil frame 50 is fixed to the support plate 30, and the geometric center of the coil frame 50 is aligned with the central axis. If a slight deviation is found between the geometric center of the coil frame 50 and the central axis through measurement, the preload of the adjusting bolts 3131 can be adjusted to finely adjust the alignment of the geometric center of the coil frame 50 with the central axis. Once the centering chuck 20 is fixed, the rotating part 200 of the centering chuck 20 is blocked and limited by the stop 11 set in the slide groove 101 on the edge of the chassis 10. After centering and fixing are completed, the rotation drive assembly is started to drive the support plate 30 and the coil frame 50 to rotate synchronously for winding.

[0067] The high-temperature superconducting winding fixture provided by this utility model overcomes the problem of low coaxiality caused by the reliance on manual alignment in existing fixtures. It also breaks through the limitations of the existing fixture chuck assembly, which has a limited stroke adjustment range, narrow applicability range, and limited applicability to single shapes. At the same time, it also solves the defects of existing fixtures, such as the lack of fine-tuning margin, the separation of clamping and rotation functions, and the low integration of fixture structure with the rotating platform.
