Description

Technical Field

[0001] The utility model relates to the technical field of superconducting magnets, in particular to a winding tooling for a special-shaped coil. Background Art

[0002] Saddle-shaped multi-pole coils (dipole, quadrupole, and hexapole coils) can generate static magnetic fields with different field patterns and have very wide applications in superconducting magnets for accelerators, superconducting magnets for single crystal growth, and superconducting magnets for magnetohydrodynamic propulsion. Such coils belong to special-shaped coils, with circular arc-shaped inner and outer surfaces and an included angle in the straight-edge section. For example, the included angle of the straight-edge section of the ion source hexapole coil is 60°. During the winding process, since circumferential stress cannot be applied to the wire in the straight-edge section, the wire is in a relaxed state in the direction perpendicular to the wire, while the circular arc sections at both ends of the straight-edge section are subjected to outward circumferential stress. Driven by the circumferential stress, the wire in the straight-edge section is prone to bounce outward. As the number of winding layers of the coil increases, it is very difficult for the wire in the straight-edge section to fit well with the coil skeleton, and the wire is prone to dislocation. The difficulty of manufacturing such coils is much greater than that of solenoid coils. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0034] Refer to Figures 1-11, a winding tool for a special-shaped coil, including a side plate 1. A ball head wire pressing device is arranged on the outer surface of the side plate 1. The ball head wire pressing device includes a horizontal support plate 21, and the flipping of the horizontal support plate 21 drives the coil 31 to flip.

[0035] In order to drive the horizontal support plate 21 to rotate, the ball head wire pressing device further includes a motor 2. The motor 2 is fixedly installed on the outer surface of the side plate 1. The output shaft of the motor 2 is fixedly installed on the outer surface of the horizontal support plate 21 through a coupling. The horizontal support plate 21 is connected to the motor 2 through a coupling. The motor 2 is fixedly installed on the side plate 1 through a support plate. One end of the output shaft of the motor 2 is fixedly installed on the outer side surface of the side plate 1 through a bearing, so that the motor 2 can drive the horizontal support plate 21 to flip synchronously, so as to adjust the angle when the coil 31 is wound, fit the winding at multiple angles, which greatly facilitates the use of operators and improves work efficiency.

[0036] In order to fix the quick-release mobile base 3 without affecting its disassembly, a quick-release mobile base 3 is slidably clamped on the outer surface of the horizontal support plate 21. A universal jacking pressure rod 4 is slidably clamped on the outer surface of the quick-release mobile base 3.

Through the sliding clamping connection between the quick-release mobile base 3 and the universal jacking pressure rod 4, multiple arc steps are provided on the quick-release mobile base 3 for the universal jacking pressure rod 4 to be fixed at multiple angles, so as to fit the shape of the coil 31 at multiple angles.

[0037] In order to fit the shape of the coil 31 at multiple angles, a universal jacking pressure rod 4 is ball-jointed on the outer surface of the quick-release mobile base 3. The outer surface of the profiling block 41 contacts the outer surface of the coil 31. Through the ball-joint connection of the profiling block 41 of the universal jacking pressure rod 4, the shape of the coil 31 can be fitted at multiple angles, so as to ensure the winding quality and accuracy of the coil 31. Operators can easily compact the straight-edge section of the irregular coil 31, greatly improving the winding quality and work efficiency.

[0038] By setting up a ball head wire pressing device to adjust the winding angle, the motor 2 fixedly installed on the side plate 1 is fixedly installed with the horizontal support plate 21 to drive the horizontal support plate 21 to rotate. The horizontal support plate 21 is slidably clamped with the quick-release movable base 3, and the quick-release movable base 3 is fixedly installed with the coil 31, so as to adjust the winding angle of the coil 31 when the horizontal support plate 21 rotates.

The universal tightening pressure rod 4 and the profiling pressing block 41 are connected by a ball head and can fit the shape of the coil 31 at multiple angles, so as to ensure the winding quality and accuracy of the coil 31. The operator can easily compact the straight edge section of the irregular coil 31, greatly improving the winding quality and work efficiency, and solving the technical problem that when winding the saddle-shaped multi-pole coil 31, the above scheme is not applicable to the saddle-shaped multi-stage coil 31, and the saddle-shaped special-shaped coil 31 is in a loose state in the direction perpendicular to the wire during the winding process because the circumferential stress cannot be applied to the wire in the straight edge section.

[0039] A wire groove profiling device is arranged on the outer surface of the side plate 1. The wire groove profiling device includes a concave arc plate 71, and the movement of the concave arc plate 71 presses the coil 31.

[0040] To ensure the accuracy of the winding of the coil 31, the wire groove profiling device further includes a convex arc plate 5. The outer surface of the convex arc plate 5 is fixedly installed with the outer surface of the horizontal support plate 21 by bolts. The convex arc plate 5 is fixed on the horizontal support cross plate by means of step positioning and bolts, which is convenient for disassembly while fixing it, so as to ensure the accuracy of the winding of the coil 31.

[0041] To enable the slider 7 to move on the slide rail type wire pressing and fixing cross beam 61, a saddle-shaped six-stage skeleton 6 is fixedly installed on the outer surface of the convex arc plate 5. The outer surface of the saddle-shaped six-stage skeleton 6 is fixedly installed with the slide rail type wire pressing and fixing cross beam 61 by bolts through a support block. The convex arc plate 5 and the saddle-shaped six-stage skeleton 6 are fixedly installed to support it. There are steps on the horizontal support plate 21 that cooperate with the convex arc plate 5 to ensure the installation accuracy. The saddle-shaped six-stage skeleton 6 and the slide rail type wire pressing and fixing cross beam 61 are fixedly installed by bolts through a support block, which is convenient for adjusting its position while fixing it, so that the slider 7 can move on the slide rail type wire pressing and fixing cross beam 61 to adjust the shape of the coil 31.

[0042] In order for the concave arc plate 71 to move together with the slider 7, the slide rail type wire pressing and fixing cross beam 61 is fixedly installed with the slider 7 by bolts. The outer surface of the slider 7 and the outer surface of the concave arc plate 71 are reversely pressed by a screw rod. The concave arc plate 71 is connected to the slider 7 by a screw rod and can move together with the slider 7 on the slide rail type wire pressing and fixing cross beam 61, and can be attached to the saddle-shaped six-stage skeleton by the reverse pressing method, making the wire groove shape flexible and precise, greatly saving the cost of directly machining such irregular curved surface grooves, making it possible to wind the coil 31, and being flexible and providing convenience for subsequent processes such as impregnation, and can achieve the full fitting of the wire groove to the shape of the theoretical coil 31.

[0043] By setting a wire groove profiling device to adjust the shape of the profiled wire groove, the convex arc plate 5 and the horizontal support plate 21 are fixedly installed by bolts and positioned by steps. The convex arc plate 5 is fixedly installed with the saddle-shaped six-stage skeleton 6. The saddle-shaped six-stage skeleton 6 and the slide rail type wire pressing and fixing cross beam 61 are fixedly installed by bolts through a support block. The slide rail type wire pressing and fixing cross beam 61 and the slider 7 are fixedly installed by bolts. The slider 7 and the concave arc plate 71 are threadedly connected by a screw rod, so that it moves together with the slider 7 and is attached to the saddle-shaped six-stage skeleton 6 by the reverse pressing method. The concave arc plate 71 is reversely pressed by the screw locking method of the slider 7 and the whole device is attached to the upper arc surface of the saddle-shaped six-stage skeleton 6, thereby forming a profiling space for the wire groove, making the wire groove shape flexible and precise, greatly saving the cost of directly machining such irregular curved surface grooves, making it possible to wind the coil 31, and being flexible and providing convenience for subsequent processes such as impregnation, and can achieve the full fitting of the wire groove to the shape of the theoretical coil 31, solving the technical problem that when winding the saddle-shaped multi-pole coil 31, the arc segments at both ends of the straight edge section are subjected to outward circumferential stress, and the wires in the straight edge section are easily bounced outward under the drive of the circumferential stress. As the number of winding layers of the coil 31 increases, it is difficult for the wires in the straight edge section to fit well with the coil 31 skeleton, and the wires are prone to dislocation.

[0044] Working principle: When the winding angle needs to be adjusted, the horizontal support cross plate is installed on the two end side plates 1 through bearings and can be flipped relatively. The motor 2 is connected to the horizontal support plate 21 through a coupling. Driven by the motor 2, the whole winding tooling is flipped at a preset angle. Due to the characteristics of winding the saddle-shaped special-shaped coil 31, the straight line segment wires on the side of the coil 31 are easy to bulge. Therefore, the quick-release movable base 3 is fixed on the horizontal support plate 21 by the quick-insert fixing method on the side. The universal jacking pressure rod 4 is then matched with the quick-release movable base 3 through an arc, and then drives the profiling pressing block 41 to press the straight line segment of the coil 31 to press the coil 31 tightly. This mechanism can be adjusted at multiple angles and the position of the pressing surface can be adjusted arbitrarily, so that each layer of wire can be compacted during the winding process of the coil 31 and the winding is flat;

[0045] When it is necessary to adjust the shape of the profiling wire groove, the convex arc plate 5 is fixed on the horizontal support cross plate by means of step positioning and bolts. The middle saddle-shaped six-stage skeleton 6 is then fixed on the convex arc plate 5 by bolts. There is a sliding rail type wire pressing and fixing cross beam 61 above, which is fixed on the middle saddle-shaped six-stage skeleton 6 by bolts through a support block. The concave arc plate is fixed on the slider 7 by a screw. The slider 7 is in sliding fit with the upper sliding rail type wire pressing and fixing cross beam 61. In this way, the position of the concave arc plate can be adjusted by adjusting the position of the slider 7, and then the concave arc plate is reversely pressed by the screw to make it completely fit with the middle saddle-shaped six-stage skeleton 6. Thus, an adjustable profiling wire groove is formed. This can greatly reduce the processing cost, shorten the processing time, and has a high profiling degree, making it easy to control the shape of the coil 31 winding. It is convenient to disassemble and assemble. This tooling can rotate synchronously with the horizontal axis of the winding machine, and can rotate coordinately with the motor 2 of the ball head wire pressing device and the horizontal turntable of the winding machine to achieve synchronous controllability of the winding angle and ensure the winding quality of the coil 31;

[0046] When the coil 31 is wound, the horizontal turntable of the winding machine rotates, and the motor 2 drives the entire tooling to flip according to the set phase angle to ensure that the winding wire cuts into the tooling horizontally. When a bundle of wires is wound, the universal jacking pressure rod 4 is screwed to reversely press the profiling pressure block 41 to tightly fix the wire on the side. After that, it enters the arc edge winding. After winding another straight edge section, the wire is also tightly fixed by the side pressing mechanism. Then it enters the arc edge winding again. The motor 2 drives the tooling to flip according to the set phase angle to ensure that the winding wire cuts into the tooling horizontally. Then the side pressing mechanism is loosened, and after the wire is wound, it is pressed again. In this way, the coil 31 is completely wound in the required shape by repeating the process.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
