Description

Technical Field

[0001] This utility model relates to the field of large triaxial magnetic field coil technology, specifically a hinged, openable triaxial coil structure. Background Technology

[0002] Currently, large triaxial magnetic field coils (such as cage coils used for materials testing and biomagnetic experiments) have the following drawbacks:

[0003] Limitations of enclosed structure: Traditional triaxial coils are fixed in a cubic or spherical cage structure with three sets of coils (X / Y / Z). When installing large samples (such as mechanical parts or living organisms), the entire coil needs to be disassembled, which is time-consuming and can easily damage the equipment.

[0004] Repeated disassembly and reassembly can damage the uniformity of the magnetic field: repeated disassembly and reassembly can cause mechanical deformation or displacement of the coil, which can destroy the original magnetic field calibration (the uniformity can deteriorate from ±0.1% to more than ±1%).

[0005] High operational risk: Disassembling heavy coils requires hoisting equipment, posing a risk of injury from falling objects;

[0006] Maintenance difficulties: When the coil is damaged, the entire system needs to be disassembled, resulting in high repair costs. Utility Model Content

[0007] The purpose of this invention is to provide a hinged, openable triaxial coil structure to solve the problems mentioned in the background art, such as the limitations of the closed structure of existing large triaxial magnetic field coils, damage to magnetic field uniformity due to repeated disassembly and assembly, high operational risks, and difficult maintenance.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a hinged, openable triaxial coil structure, comprising a profile truss, an X-axis coil winding frame, a Y-axis coil winding frame, and a Z-axis coil winding frame. The profile truss, X-axis coil winding frame, Y-axis coil winding frame, and Z-axis coil winding frame are connected by snap fasteners. The coil system composed of the profile truss, X-axis coil winding frame, Y-axis coil winding frame, and Z-axis coil winding frame has an overall rectangular structure. An X-axis coil is wound on the X-axis coil winding frame, and a Y-axis coil and Z-axis coil winding frame are wound on the Y-axis coil winding frame. A Z-axis coil is wound on a coil winding skeleton. The top and bottom surfaces of the coil system are non-coil-covered surfaces, while the sides are coil-covered surfaces. One side is set as a hinged, openable triaxial coil door. The coil door includes a Z-axis coil disconnected at the docking end and a rotating Z-axis coil winding skeleton disconnected at the docking end and hinged to the adjacent Z-axis coil winding skeleton on the rotating side via a heavy-duty hinge. Two heavy-duty connectors are installed on the two free ends of the Z-axis coil. The two heavy-duty connectors on the two free ends of the same Z-axis coil are connected to the upper and lower shells by snap-fit. When closed, the Z-axis coil circuit is connected.

[0009] The coil gate is also equipped with a complete closed-axis coil winding skeleton and a Y-axis coil wound on the Y-axis coil winding skeleton.

[0010] The Z-axis coil winding frame and the Y-axis coil winding frame are connected by a disc buckle.

[0011] The heavy-duty hinge consists of an upper connecting plate, a lower connecting plate, a self-lubricating bearing, and a base. The self-lubricating bearing is installed in the rotation holes of the upper and lower connecting plates, which are fixed to the left and front sides of the Z-axis coil frame by the base.

[0012] The docking end of the coil door is also equipped with a C-type latch and a corner fastener. The docking end of the rotating Z-axis coil winding skeleton is connected to the end of the Z-axis coil winding skeleton on the adjacent surface through the C-type latch and the corner fastener.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model has the following features:

[0015] This invention connects one side of the Z-axis coil to the base via a heavy-duty hinge (such as a self-lubricating bearing hinge), while the other side is a free end. The free end adopts a C-type locking design, which automatically aligns and locks when closed. The free end uses a miniature multi-channel connector, which connects the circuits of each axis coil when closed. The sample installation time is reduced from several hours to within 10 minutes, making it particularly suitable for experimental scenarios where samples are frequently changed. The precision reset design ensures that the change in magnetic field uniformity before and after opening and closing is ≤±0.01%, achieving zero compromise in magnetic field performance. It saves 30% of maintenance and disassembly costs compared to traditional split-type triaxial coils. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1-2 As shown, this invention provides an openable triaxial magnetic field coil system based on a hinged structure, including a profile truss 1, an X-axis coil winding frame 2, a Y-axis coil winding frame 3, and a Z-axis coil winding frame 4. The profile truss 1, X-axis coil winding frame 2, Y-axis coil winding frame 3, and Z-axis coil winding frame 4 are connected by a snap fastener 21. The coil system composed of the profile truss 1, X-axis coil winding frame 2, Y-axis coil winding frame 3, and Z-axis coil winding frame 4 has an overall rectangular structure. An X-axis coil 5 is wound on the X-axis coil winding frame 2, and a Y-axis coil 7 and a Z-axis coil are wound on the Y-axis coil winding frame 3. A Z-axis coil 8 is wound on the wire frame 4. The top and bottom surfaces of the coil system are non-coil-covered surfaces, while the sides are coil-covered surfaces. One side is set as a coil door 9 with a hinged, openable triaxial coil structure. The coil door 9 includes a Z-axis coil 8 disconnected at the docking end and a rotating Z-axis coil winding frame 11 disconnected at the docking end and hinged to the adjacent Z-axis coil winding frame 4 on the rotating side by a heavy-duty hinge 10. Two heavy-duty connectors 6 are respectively installed on the two free ends of the Z-axis coil 8. The two heavy-duty connectors 6 at the two free ends of the same Z-axis coil 8 are connected to the upper and lower shells by a snap-fit ​​20. When closed, the circuit of the Z-axis coil 8 is connected.

[0027] The coil gate 9 is also equipped with a complete closed-axis coil winding skeleton 3 and a Y-axis coil 7 wound on the Y-axis coil winding skeleton 3. The rotating Z-axis coil winding skeleton 11 is connected to the Y-axis coil winding skeleton 3 by a disc buckle 21.

[0028] like Figure 3 , Figure 7 and Figure 8As shown, the heavy-duty hinge 10 comprises an upper connecting plate 12, a lower connecting plate 13, a self-lubricating bearing 14, and a base 15. The self-lubricating bearing 14 is installed in the rotation holes of the upper connecting plate 12 and the lower connecting plate 13. The upper connecting plate 12 and the lower connecting plate 13 are fixed to the left and front sides of the Z-axis coil winding frame 4 by the base 15.

[0029] The self-lubricating bearing 14 includes a thrust bearing 22 and a through shaft 19. Specifically, a bushing 18 is coaxially disposed between two spaced lower connecting plates 13, and a thrust bearing 22 is disposed between an upper connecting plate 12 and an adjacent lower connecting plate 13. The two sets of upper connecting plates 12 are connected to the Z-axis coil winding frame 4 through a base 15, and the two sets of lower connecting plates 13 are connected to the rotating Z-axis coil winding frame 11 through a base 15. A through shaft 19 passes vertically through the first upper connecting plate 12, the first thrust bearing 22, the first lower connecting plate 13, the bushing 18, the second lower connecting plate 13, the second thrust bearing 22, and the second upper connecting plate 12, connecting the upper connecting plate, the lower connecting plate 13, the bushing 18, and the thrust bearing 22 in series. The thrust bearing 22 is used to bear the axial load applied to the through shaft by the upper connecting plate and allows the upper connecting plate to rotate relative to the lower connecting plate 13 and the through shaft. The through shaft is axially secured by a lock nut, ensuring axial preload on the assembly and providing a core torque transfer path.

[0030] like Figure 4-6 As shown, the docking end of the coil door 9 is also equipped with a C-type latch 16 and a corner fastener 17. The docking end of the rotating Z-axis coil winding frame 11 is connected to the end of the adjacent Z-axis coil winding frame 4 through the C-type latch 16 and the corner fastener 17. The inner side of the C-type latch 16 is tightly fitted to the end of the rotating Z-axis coil winding frame 11 and the side wall of the corner fastener 17 at the end of the rotating Z-axis coil winding frame 11. One end of the corner fastener 17 at the end of the rotating Z-axis coil winding frame 11 is fixed to the rotating Z-axis coil winding frame 11 by bolts, and the other end is automatically aligned with the corner fastener 17 of the adjacent Z-axis coil winding frame 4 when closed through a positioning screw hole. The corner fasteners 17 on both sides are locked by bolts. The free end of the Z-axis coil 8 at the docking end can be quickly connected and closed using a heavy-duty connector 6 without affecting performance. Specifically, when each coil is wound, the two ends of the copper wire are connected to the pin end and the body end of the heavy-duty connector 6, respectively. The coil is further secured by the buckles 20 on the upper and lower docking shells of the heavy-duty connector 6. When opening and closing the coil door 9, simply open the buckle 20, remove the heavy-duty connector 6, and remove the bolts in the C-type lock 16 and the corner fastener 17 to achieve quick opening and closing of the coil door 9.

[0031] In this invention, a heavy-duty hinge enables the single-sided coil door to rotate and open more than 90°. After the coil door is opened, the sample can be quickly placed inside the coil system. When the coil door is closed, the Z-axis coil is closed and energized, and the sample is tested in the magnetic field generated by the coil system. The coil door setting reduces the sample installation time by 80%.

[0032] In this invention, when the coil gate is closed, a precision docking mechanism ensures that the coil reset accuracy is ≤0.1mm, maintaining the original magnetic field uniformity (e.g., ±0.05%@10cmDSV).

[0033] This utility model integrates mechanical locking and electrical interlocking to prevent accidental opening and closing while the circuit is energized.

[0034] This invention supports the individual disassembly of any shaft coil, reducing maintenance costs.
