Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of superconducting coil, and particularly relates to a winding tool and a winding method of superconducting coil. BACKGROUND

[0002] Generally, the superconducting coil needs to be wound on the frame body by the winding tool, and then the superconducting coil is obtained. Taking a magnetic pulling single crystal superconducting coil as an example, the magnetic pulling single crystal superconducting coil is designed as a ring, and the corresponding frame body is also a ring structure. However, when winding on the winding tool, the ring-shaped frame body needs to be installed on the winding machine and needs to be rotated around the winding machine, so the common structure is to set a rotating shaft in the middle of the frame body, and then the two ends of the rotating shaft are fixedly installed on the winding machine, and the frame body and the rotating shaft rotate and wind.

[0003] The existing rotating shaft and frame body are fixedly connected, for example, see Figure 1 Generally, the rotating shaft 1 and the side plate 3 on the frame body 2 are rigidly fixedly connected, so that the rotating shaft 1 and the frame body 2 cannot be adjusted after being fixedly installed, and cannot be adjusted when the surface round runout or surface total runout of the frame body 2 does not meet the requirements. The surface round runout refers to the radial runout of each point on the surface of the frame body slot from the reference axis when the frame body slot rotates one round. If the round runout is out of tolerance, the frame body slot will rub against the stator core or other components during rotation, affecting the performance of the equipment. The surface total runout refers to the comprehensive deviation of each point on the surface of the frame body slot from the reference axis during rotation. The total runout out of tolerance will cause the overall assembly precision of the frame body slot to decrease, for example, the axial fit between the frame body slot and the core is poor, which may cause electromagnetic noise or mechanical vibration.

[0004] The common reasons for the surface round runout or surface total runout are generally caused by assembly errors, for example, assembly errors may occur when the rotating shaft 1 is fixed, the side plate 3 of the frame body 2 is fixed, or the frame body 2 is installed on the winding machine. Especially, errors cannot be avoided during the processing and assembly of the rotating shaft 1 and the frame body 2. However, because the rotating shaft 1 and the frame body 2 are fixedly connected in the prior art, the frame body 2 cannot be adjusted in time and accurately when the surface round runout and the surface total runout of the frame body 2 do not meet the winding technical requirements when the frame body 2 rotates on the winding machine, which may cause the wound coil to be unqualified, and finally cause the magnetic field uniformity of the superconducting coil after excitation to not meet the design requirements of the magnet, and even the magnet may lose superconductivity and be damaged, causing economic losses. However, the common solutions to the surface round runout or surface total runout exceeding the error in the prior art are only rework or scrapping. The rework has a long processing cycle, the rework quality cannot be guaranteed, and there is a certain scrapping probability.

[0005] Therefore, when the winding machine is used to wind the superconducting wire on the bobbin body, the bobbin body and the rotating shaft cannot be adjusted after being installed, which leads to unqualified winding coils. SUMMARY

[0006] The purpose of the present application is to solve the problem that the winding machine cannot be adjusted after the bobbin body and the rotating shaft are installed when the winding machine is used to wind the superconducting wire on the bobbin body.

In addition, the shaft end abutting piece has an arc-shaped abutting part adapted to the outer wall of the rotating shaft.

For example, when the surface roundness runout or the surface total runout of the bobbin body does not meet the winding requirement, the position of the shaft end abutting part relative to the center of the bobbin body is adjusted by adjusting the radial extension part, so that the surface roundness runout and the surface total runout of the adjusted bobbin body meet the winding requirement, and the position of the bobbin body on the rotating shaft can be adjusted in the axial direction of the rotating shaft, and the winding tool has the advantages of simple structure and simple and convenient adjustment.

[0111] In the present application, each support assembly 400 can be provided with different numbers of abutting components 410 according to requirements, for example, 3, 4, 6 or even more abutting components 410, and the plurality of abutting components 410 are uniformly arranged along the circumference of the line frame body 100, for example, when 3 abutting components 410 are arranged, the central angle corresponding to the adjacent two abutting components 410 is 120°, and when 4 abutting components 410 are arranged, the central angle corresponding to the adjacent two abutting components 410 is 90°. Preferably, in the present embodiment, two support assemblies 400 are provided with 4 abutting components 410 and extend in the radial direction of the line frame body 100. By adjusting the 4 abutting components 410 at the end of the line frame body 100, the position of the rotating shaft 200 in the 4 directions at the end of the line frame body 100 can be adjusted. Therefore, the more the number of abutting components 410 arranged along the circumference of the line frame body 100, the higher the adjustable accuracy of the line frame body 100 and the rotating shaft 200 in the Y-axis and Z-axis directions of the three-dimensional coordinate system.

[0112] Further, when each radial extension 411 adjusts the position of the adjusting shaft end abutting member 412 relative to the center of the line frame body 100 in the radial direction, the radial extension 411 can be adjusted in the radial direction in various ways such as threaded rotation adjustment, sliding rail sliding adjustment, adjustment member telescopic adjustment, etc.

[0113] For example, when the radial extension 411 is adjusted in the threaded rotation adjustment mode, the radial extension 411 can be provided as two threaded rods that are threadedly sleeved with each other, and the length of the radial extension 411 is adjusted by threadedly sleeving.

[0114] For another example, when the radial extension 411 is adjusted in the sliding rail sliding adjustment mode, the radial extension 411 can be provided as two sliders that are slidably sleeved with each other, and the length of the radial extension 411 is adjusted by slidably sleeving.

[0115] For another example, when the radial extension 411 is adjusted in the adjustment member telescopic adjustment mode, the radial extension 411 can be provided as two radial extensions that are connected by an adjustment member, and the length of the radial extension 411 is adjusted by adjusting the length of the radial extension. Those skilled in the art can design and adjust according to actual requirements, which is not uniquely limited in the present application.

[0116] Further, the shaft end abutting member 412 can be provided as an abutting protrusion, an abutting wheel or other abutting members, and the side wall portion close to the rotating shaft 200 of the abutting protrusion or the abutting wheel is provided with an arc-shaped abutting portion adapted to the rotating shaft 200. The position of the shaft end abutting member 412 relative to the center of the line frame body 100 can be adjusted by adjusting the radial extension 411, which can be conveniently and flexibly adjusted.

[0117] The winding tool for the superconducting coil disclosed in the embodiment can adjust the position of the bobbin body 100 relative to the rotating shaft 200, for example, referring to Figure 2 or Figure 3 For example, the bobbin body 100 is adjusted relative to the rotating shaft 200, the shaft end abutting piece 412 of the two support assemblies 400 and the outer wall of the rotating shaft 200 are first adjusted to be relatively movable, and then the bobbin body 100 is adjusted along the axis direction of the rotating shaft 200, so that the displacement of the rotating shaft 200 in the X-axis direction of the bobbin body 100 can be adjusted, and by adjusting the length of the plurality of abutting components 410 in the radial direction of the bobbin body 100, the displacement of the rotating shaft 200 in the Y-axis and Z-axis directions of the bobbin body 100 can be adjusted, for example, when four abutting components 410 are arranged in the application, the directions of two abutting components 410 are the same as the Y-axis and Z-axis directions, and the adjustment can be completed by adjusting the corresponding abutting components 410.

[0118] Therefore, the winding tool for the superconducting coil disclosed in the application can adjust the position of the bobbin body 100 relative to the rotating shaft 200 along the X-axis, Y-axis and Z-axis directions of the three-dimensional coordinate system, or adjust the position of the rotating shaft 200 relative to the bobbin body 100, that is, the bobbin body 100 can be adjusted even after the rotating shaft 200 is fixedly installed on the winding machine 600. For example, when the surface roundness or surface total runout of the bobbin body 100 does not meet the winding requirements, the position of the shaft end abutting piece 412 relative to the center of the bobbin body 100 is adjusted by adjusting the radial extension 411, and the position of the bobbin body 100 relative to the rotating shaft 200 is adjusted from three directions of the three-dimensional coordinate system of the bobbin body 100, so that the surface roundness and surface total runout of the adjusted bobbin body 100 meet the winding requirements, and the winding tool has the advantages of simple structure and multiple direction adjustment.

[0119] The surface roundness refers to the radial runout of each point on the surface of the bobbin body wire slot when rotating one circle. If the roundness is out of tolerance, the wire slot will rub against the stator core or other components during rotation, affecting the performance of the equipment. The surface total runout refers to the comprehensive deviation of each point on the surface of the bobbin body wire slot relative to the reference axis during rotation. The total runout out of tolerance will cause the overall assembly precision of the wire slot to decrease, for example, the axial fit between the wire slot and the core is poor, which may cause electromagnetic noise or mechanical vibration.

[0120] The embodiment further discloses a winding tool for a superconducting coil, referring to Figure 3 and Figure 4Each radial extension 411 comprises a fixed link 4111 extending in the radial direction and a radial adjusting member arranged at one end of the fixed link 4111 close to the rotating shaft 200, and the other end of the fixed link 4111 is fixed to the shaft end of the corresponding side of the frame main body 100, and the radial adjusting member can be adjusted in the radial direction.

[0121] Specifically, in the present embodiment, the radial adjusting member can be arranged as a threaded sleeve rod, a sleeved slider, a radial adjusting plate, etc. which can be adjusted in the radial direction, and the present embodiment does not make specific limitations thereon. With the design of such a structure, the fixed link 4111 provides support to the radial adjusting member along the radial direction, and the radial adjusting member is adjusted in the radial direction in an expansion and contraction manner, and the adjustment mode is simple and the adjustment accuracy is high.

[0122] Further preferably, referring to Figure 3 and Figure 4 , the radial adjusting member comprises a fixed plate 4112 and an adjusting plate 4113 which are arranged opposite to each other and spaced apart in the radial direction, one side of the fixed plate 4112 is fixed to one end of the fixed link 4111 close to the rotating shaft 200, and the other side of the adjusting plate 4113 is movably arranged on the other side of the fixed plate 4112 in the radial direction, and the shaft end abutting member 412 is fixed to the other side of the adjusting plate 4113 close to the rotating shaft 200, and in the present embodiment, the shaft end abutting member 412 is arranged as an abutting roller 4121.

Among them, the adjusting member 4114 comprises an adjusting bolt extending in the radial direction, and a plurality of adjusting bolts are arranged at positions close to the corners of the outer periphery of the fixed plate 4112 and the adjusting plate 4113.

[0124] Specifically, in the present embodiment, the fixed plate 4112 and the adjusting plate 4113 are arranged as two plates of the same structure, for example, the fixed plate 4112 and the adjusting plate 4113 can be arranged as square plates, circular plates, rectangular plates, etc. For example, when the fixed plate 4112 and the adjusting plate 4113 are arranged as circular plates, a plurality of adjusting members 4114 are arranged uniformly and spaced apart along the positions close to one circle of the outer periphery of the circular plates. For example, when the fixed plate 4112 and the adjusting plate 4113 are arranged as square plates, referring to Figure 4 , one adjusting member 4114 is arranged at a position close to each of the four corners of the outer periphery of the square plate, that is, four adjusting members 4114 are arranged spaced apart between the fixed plate 4112 and the adjusting plate 4113.

[0125] It should be further explained that in the embodiment, the fixed plate 4112 and the adjusting plate 4113 are both provided as square plates, and four adjusting members 4114 are provided near the four corners. When adjusting along the radial direction of the reel body 100, not only the radial adjustment can be realized, but also the position of the plane where the adjusting plate 4113 is located in the radial direction can be adjusted, and the adjustment accuracy is higher. For example, in the initial state, the fixed plate 4112 and the adjusting plate 4113 are arranged at intervals in the radial direction, and the lengths of the four adjusting members 4114 are adjusted, so that the positions of the adjusting plate 4113 and the shaft end abutting member 412 in the radial direction are adjusted, and then the positions of the arc-shaped abutting portion of the shaft end abutting member 412 and the rotating shaft 200 are adjusted. For example, when only one, two or three of the four adjusting members 4114 are adjusted, the adjusting plate 4113 can be inclined relative to the fixed plate 4112, so that the position or angle of the plane where the adjusting plate 4113 and the shaft end abutting member 412 are located is adjusted, that is, the linear adjustment of the four abutting members 410 in the radial direction can be realized, or the plane adjustment of the shaft end abutting member 412 of each abutting member 410 in the direction perpendicular to the radial end face can be realized, and the adjustment accuracy is higher.
