Description

Technical Field

[0001] This utility model relates to the field of superconducting coil winding technology, specifically to a superconducting coil winding device. Background Technology

[0002] Application number CN202321930656.4 discloses a superconducting coil winding device, including a winding frame, coil outer terminals, and a superconducting strip. The coil outer terminals are located around the periphery of the winding frame. One end of the superconducting strip is fixedly connected to the winding frame, and the superconducting strip is wound around the periphery of the winding frame. The other end of the superconducting strip is fixedly connected to the coil outer terminals. One of the winding frame and the coil outer terminals serves as the input terminal for input current, and the other serves as the output terminal for output current. During winding, the above-mentioned superconducting coil winding device can continuously press the superconducting strip with clamping rollers, thereby ensuring the tight winding of multiple layers of superconducting strip and guaranteeing the performance of the superconducting strip coil. However, the current winding device has a significant problem: the clamping force is inconvenient to adjust.

[0003] Because the clamping force cannot be flexibly adjusted, it brings many disadvantages during the actual winding process. On the one hand, if the clamping force remains constant, it cannot be adaptively adjusted according to different specifications of superconducting tapes and different winding requirements. For some thinner or more fragile superconducting tapes, excessive clamping force may damage the tape, affecting its superconducting performance or even causing it to break, increasing production costs and material waste. On the other hand, the required winding tightness varies for superconducting coils with different performance requirements. A fixed clamping force cannot meet diverse winding needs, limiting further optimization of superconducting coil performance. Utility Model Content

[0004] The purpose of this invention is to provide a winding device for superconducting coils to solve the problems mentioned in the background art.

[0005] Technical solution: A winding device for a superconducting coil includes a winding frame for winding an ultrasonic strip, a base, and an external terminal of the coil. A positioning seat is detachably mounted on the base. An extension arm extending toward the winding frame is provided on the side wall of the positioning seat. A clamping assembly is adjustablely mounted on the extension arm. The clamping assembly includes a mounting seat slidably mounted on the extension arm and a swing arm rotatably mounted on the mounting seat. A clamping wheel for clamping the superconducting strip during winding is rotatably mounted at the end of the swing arm away from the mounting seat.

[0006] In one specific implementation, there are two swing arms, symmetrically arranged and distributed in a figure-eight pattern, and tension springs are connected to the opposite sidewalls of the two swing arms.

[0007] The above technical solution enables the superconducting strip to be elastically compressed from two directions simultaneously, thereby meeting the winding requirements of superconducting strips of different specifications.

[0008] In one specific implementation, the base is provided with a positioning component, which includes a positioning screw, a straight slot and a slide. The positioning screw passes through the positioning seat and is threadedly connected to the base. The straight slot is opened through the base along the length of the extension arm. The slide is slidably connected inside the straight slot and connected to the mounting base.

[0009] The above technical solution allows the slide block to slide within the straight groove, adjusting the position of the mounting base and the swing arm, thereby adjusting the pressure applied by the clamping wheel to the superconducting belt.

[0010] In one specific implementation, a side groove extending along the length direction is provided on the side wall of the extension arm. The side groove is connected to the straight groove. A fixing rod is slidably connected in the side groove. One end of the fixing rod extends into the straight groove and is fixedly connected to the side wall of the slide block. The other end of the fixing rod extends outward through the side groove and is threadedly connected to a fixing nut.

[0011] The above technical solution enables the fixed rod to move the slide block within the side groove, thereby preventing radial displacement of the pressure wheel during the winding process.

[0012] In one specific implementation, the positioning seat has a countersunk hole adapted to the positioning screw.

[0013] The above technical solution can fix the positioning seat to the base by positioning screws, ensuring the stability of the positioning component and the adjustment component during operation.

[0014] In one specific implementation, the base is provided with positioning holes for mounting the winding skeleton.

[0015] The above technical solution enables the winding skeleton to be installed in the base.

[0016] In one specific implementation, the base has several receiving slots arranged in an array along the circumference, and the receiving slots are adapted to the positioning screw.

[0017] The above technical solution facilitates the fixing of the positioning component and the clamping component on the base for use, and makes it easy to remove the positioning component and the clamping component after the winding is completed.

[0018] Beneficial effects: This utility model places the superconducting belt between two clamping rollers, and adjusts the position of the mounting base and the swing arm by sliding the slide block in the straight groove to adjust the distance between the clamping rollers and the superconducting belt, thereby achieving the effect of adjusting the clamping pressure of the superconducting belt. It not only meets the winding requirements of superconducting belts of different specifications, but also has a wide range of applications, improves the winding quality, and does not affect the performance of the superconducting belt itself.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4A winding device for a superconducting coil, hereinafter referred to as "the device". The device includes a winding frame 1 for winding a superconducting strip, a base 2, and coil external terminals 3. A positioning seat 41 is detachably mounted on the base 2. An extension arm 43 extending toward the winding frame 1 is provided on the side wall of the positioning seat 41. A clamping assembly 5 is adjustablely mounted on the extension arm 43. The clamping assembly 5 includes a mounting seat 51 slidably mounted on the extension arm 43 and a swing arm 52 rotatably mounted on the mounting seat 51. A clamping wheel 53 for clamping the superconducting strip during winding is rotatably mounted at the end of the swing arm 52 away from the mounting seat 51.

[0027] By adjusting the position of the mounting base 51 within the extension arm 43, the swing arm 52 can open and close, thereby controlling the pressure applied to the superconducting belt by the clamping wheel 53. This satisfies the winding requirements of superconducting belts of different specifications and has a wide range of applications. Furthermore, the use of double clamping wheels 53 can improve the winding quality without affecting the performance of the superconducting belt itself.

[0028] It should be noted that the superconducting coil winding device provided in this application includes a winding frame 1, a base 2, an outer coil terminal 3, and a superconducting strip. One end of the superconducting strip is fixedly connected to the winding frame 1 and is wound around the periphery of the winding frame 1. The other end of the superconducting strip is fixedly connected to the outer coil terminal 3. One of the winding frame 1 and the outer coil terminal 3 serves as the input terminal for inputting current, and the other serves as the output terminal for outputting current. This allows current to be directly injected through the winding frame 1 or the outer coil terminal 3 and conducted through the superconducting strip to the winding frame 1 or the outer coil terminal 3, thereby realizing the energizing and wiring function of the superconducting coil winding device.

[0029] See Figure 4 There are two symmetrically arranged swing arms 52, which are distributed in a figure-eight shape, and tension springs 54 are connected to the opposite side walls of the two swing arms 52.

[0030] Specifically, when using a single clamping roller 53 to clamp the superconducting tape, pressure can often only be applied from one direction, which can easily lead to uneven stress on the superconducting tape. This may cause localized loosening or over-tightening of the superconducting tape during winding, affecting the overall performance and stability of the coil. Moreover, a single clamping roller 53 has poor adaptability to superconducting tapes of different widths, making it difficult to ensure uniform clamping force across the entire width of the superconducting tape.

[0031] In contrast, this design employs a dual-pressure roller 53 design. First, the dual-pressure roller 53 can simultaneously press the superconducting strip from two directions, ensuring more uniform force distribution on the superconducting strip. Furthermore, the tension spring 54 allows the pressure roller 53 to elastically press against the surface of the superconducting strip, which helps improve the tightness of the superconducting coil winding, reduces internal voids, and thus enhances coil performance. Second, the dual-pressure roller 53 offers better adaptability to superconducting strips of different widths.

[0032] See Figure 2 It also includes a positioning component 4, which includes a positioning screw 42, a straight slot 44, and a slide 46. The positioning screw 42 is threaded onto the base 2, and the positioning seat 41 is fixed to the base 2 by the positioning screw 42. The straight slot 44 is opened through the extension arm 43 along its length direction, and the slide 46 is slidably connected inside the straight slot 44. The mounting seat 51 is connected to the slide 46.

[0033] Specifically, the position of the mounting base 51 and the degree of opening and closing of the swing arm 52 can be adjusted by sliding the slide block 46 within the straight groove 44, thereby adjusting the distance between the pressure roller 53 and the superconducting belt and the amount of pressure applied by the pressure roller 53 to the superconducting belt.

[0034] See Figure 3 The side wall of the extension arm 43 is provided with a side groove 45 extending along its length direction. The side groove 45 is connected to the straight groove 44. A fixing rod 47 is slidably connected inside the side groove 45. One end of the fixing rod 47 extends into the inside of the straight groove 44 and is fixedly connected to the side wall of the slide block 46. The other end of the fixing rod 47 passes through the side groove 45 and extends outward and is threadedly connected to a fixing nut 48.

[0035] Specifically, the position of the slide block 46 can be fixed by the cooperation of the fixing rod 47 and the fixing nut 48 to prevent radial displacement of the pressure wheel 53 during the winding process.

[0036] See Figure 4 The positioning seat 41 has a countersunk hole, and the positioning screw 42 is set inside the countersunk hole.

[0037] Specifically, the countersunk hole on the positioning seat 41 can hide the positioning screw 42, preventing the positioning screw 42 from affecting the winding of the superconducting strip during the winding process.

[0038] See Figure 4 The outer wall of the fixed rod 47 away from the slide block 46 has an external thread, and the inner ring of the fixed nut 48 has an internal thread that matches the external thread.

[0039] Specifically, the external and internal threads are matched to ensure that the fixing nut 48 can be threaded onto the fixing rod 47, and the position of the slide block 46 can be locked by tightening the fixing nut 48.

[0040] See Figure 1 and Figure 4 The base 2 has a positioning hole 22 for mounting the winding skeleton 1. The base 2 also has a receiving groove 21 for the positioning screw 42 to be screwed into. There are multiple receiving grooves 21, which are arranged in a circumferential array along the top surface of the base 2.

[0041] Specifically, the multiple receiving slots 21 can be used to fix the positioning seat 41 at different positions on the base 2, which facilitates the winding of the superconducting tape. The positioning screw 42 can cooperate with the receiving slots 21 to fix the positioning component 4 and the clamping component 5 on the base 2 for use. After the winding is completed, the positioning component 4 and the clamping component 5 can be easily removed.

[0042] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
