Description

Technical Field

[0001] The invention relates to the technical field of superconducting magnets, in particular to a fine-tuning positioning device for a superconducting magnet adjusting flange used in a high-precision magnetic axis gyrotron. Background Art

[0002] Since the superconducting magnet used in the gyrotron needs to have high-precision axial magnetic field configuration requirements and the virtual room-temperature hole axis formed by the inner diameters of the upper and lower radial adjustment flanges needs to be highly coincident with the magnetic field axis during use, it is often necessary to perform high-precision fine-tuning operations on the upper and lower radial adjustment flanges of the magnet during the magnet testing phase, so that the virtual room-temperature hole axis formed by the inner diameters of the upper and lower radial adjustment flanges of the magnet and the axial magnetic field concentric axis requirement are better than 0.1, to ensure that when the ion emitter is subsequently installed, its axis can be highly coincident with the magnetic field center of the superconducting magnet used in the gyrotron.

[0003] Currently, when adjusting the upper and lower radial adjustment flanges of superconducting magnets, we need to use a radial magnetic measuring device to test the eight points of the radial magnetic field. We need to use a wrench made of non-magnetic material to rotate the four screws installed on the adjustment flange to drive the adjustment flange to move. This method cannot accurately grasp the distance the adjustment flange moves and its final position. It relies entirely on the experience of the debugging personnel. Each time, it must go through the three-step process of magnetic measurement-calculation-adjustment. When adjusting again, it is necessary to loosen at least two mutually perpendicular screws and rotate the screw adjustment flange. This cannot guarantee that the next adjustment will be better than the previous adjustment. Although the structure of the existing adjustment tooling is relatively simple, the operation process is relatively cumbersome and lengthy. The adjustment process may have a certain degree of randomness, and it is impossible to achieve rapid and precise adjustment of the adjustment flange, which seriously affects the subsequent configuration test process of the axial magnetic field.

[0004] Therefore, we will propose a high-precision superconducting magnet adjustment flange fine-tuning positioning device for a magnetic axis gyrotron to improve the adjustment efficiency and accuracy of the concentric adaptation of the virtual room temperature hole axis composed of the radial adjustment flange and the magnetic axis. Summary of the Invention

[0005] The object of the present invention is to provide a high-precision superconducting magnet adjustment flange fine-tuning positioning device for a magnetic axis gyrotron, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A superconducting magnet adjustment flange fine-tuning positioning device for a high-precision magnetic axis gyrotron comprises a superconducting magnet, wherein fine-tuning positioning devices are respectively provided at both axial ends of an outer dewar of the superconducting magnet, radial adjustment flanges are provided between the fine-tuning positioning device and the outer dewar of the superconducting magnet, magnetic disk mounting seats are provided on the inner sides of the radial adjustment flanges, a spherical bearing is provided at the center of the surface of the magnetic disk mounting seat, a rotating magnetic disk is provided on the outer side of the spherical bearing, a rotating drive rod is also provided between the two rotating magnetic disks, a radial Hall probe is connected to the surface of the magnetic disk mounting seat via a radial probe mounting seat, and the radial Hall probe is provided at both axial ends of the outer dewar of the superconducting magnet.

[0008] Further preferably, the fine-tuning positioning device includes a fixed mounting base plate fixedly connected to the axial ends of the superconducting magnet outer dewar by pins, and a transverse guide mechanism is symmetrically arranged along the transverse direction at the surface edge of the fixed mounting base plate, one end of one transverse guide mechanism is connected to a transverse adjuster, and a transverse adjustment plate is movably connected between the transverse guide mechanism and the fixed mounting base plate, and a longitudinal guide mechanism is symmetrically arranged along the longitudinal direction at the surface edge of the transverse adjustment plate, one end of one longitudinal guide mechanism is connected to a longitudinal adjuster, and a longitudinal adjustment plate is movably connected between the longitudinal guide mechanism and the transverse adjustment plate.

[0009] Further preferably, the lateral guide mechanisms include lateral support blocks symmetrically arranged along the two lateral edges of the surface of the fixed mounting base plate, and lateral support rods are arranged between the lateral support blocks on the same side in the lateral direction. Two lateral sliding bearings are also sleeved on the outside of each lateral support rod, and the lateral sliding bearings are fixedly connected to the four corners of the surface of the lateral adjustment plate.

[0010] Further preferably, a transverse movable top plate is provided on the top of one of the transverse sliding bearings of any one of the transverse guide mechanisms, a transverse adjuster is also provided on the top of the transverse support block close to the transverse movable top plate, a spherical top is also provided on the driving end of the transverse adjuster, the end of the spherical top is connected to the transverse movable top plate, and a first rebound spring is also provided between the other transverse sliding bearing and the adjacent transverse support block.

[0011] Further preferably, the longitudinal guide mechanisms include longitudinal support blocks symmetrically arranged along the two longitudinal edges of the surface of the transverse adjustment plate, and longitudinal support rods are arranged between the longitudinal support blocks on the same side in the longitudinal direction. Two longitudinal sliding bearings are also sleeved on the outside of each longitudinal support rod, and the longitudinal sliding bearings are fixedly connected to the four corners of the surface of the longitudinal adjustment plate.

[0012] Further preferably, a longitudinal movable top plate is provided on the top of one of the longitudinal sliding bearings of any one of the longitudinal guide mechanisms, a longitudinal adjuster is also provided on the top of the longitudinal support block close to the longitudinal movable top plate, a spherical top is also provided on the driving end of the longitudinal adjuster, the end of the spherical top is connected to the longitudinal movable top plate, and a second rebound spring is also provided between the other longitudinal sliding bearing and the adjacent longitudinal support block.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By utilizing the reverse thrust of the lateral adjuster, the longitudinal adjuster, and the first and second rebound springs, the lateral and longitudinal adjustment plates can be moved back and forth in the lateral and longitudinal directions by manually rotating the lateral adjuster or the longitudinal adjuster forward or backward. This design has the characteristics of easy operation and simple structure, and can accurately determine the positions of the lateral and longitudinal adjustment plates in the lateral and longitudinal directions after movement.

[0016] The fine-tuning positioning device and the rotating measuring disk are simultaneously positioned and installed on the radial adjustment flange, so that the rotating measuring disk can synchronously measure the magnetic field measurement center after the radial adjustment flange is driven by the fine-tuning positioning device, avoiding the offset of the magnetic field centers measured successively due to component disassembly, and improving the measurement accuracy and reliability of the magnetic field center positions at the upper and lower radial adjustment flanges.

[0017] The application of the rotating drive rod and the spherical bearing can not only drive the two rotating measuring disks to perform rotating magnetic measurement at the same time, but also avoid the measuring disks from getting stuck during the rotation process due to the non-perpendicularity between the rotating drive rod and the end face of the radial adjustment flange. While ensuring that the rotating measuring disks are always in a horizontal state, they can also ensure that the rotating measuring disks run smoothly during the rotation process, greatly improving the magnetic measurement efficiency.

[0018] In summary, the device can accurately adjust the concentricity of the virtual axis center formed by the two radial adjustment flanges and the measuring magnetic field axis, which improves and reduces the difficulty of the concentricity adjustment process, shortens the adjustment time, and reduces a lot of manual repetitive labor, especially for superconducting magnets used in gyrotrons with high coaxiality requirements.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In the present invention, the fine-tuning positioning device 7 includes a fixed mounting base plate 710 fixedly connected to the axial ends of the outer dewar of the superconducting magnet 5 by pins, and a transverse guide mechanism is symmetrically arranged along the transverse direction at the surface edge of the fixed mounting base plate 710, one end of which is connected to a transverse adjuster 701, and a transverse adjustment plate 711 is movably connected between the transverse guide mechanism and the fixed mounting base plate 710, and a longitudinal guide mechanism is symmetrically arranged along the longitudinal direction at the surface edge of the transverse adjustment plate 711, one end of which is connected to a longitudinal adjuster 705, and a longitudinal adjustment plate 712 is movably connected between the longitudinal guide mechanism and the transverse adjustment plate 711.

[0031] In the present invention, each transverse guide mechanism includes transverse support blocks 714 symmetrically arranged along two transverse edges of a fixed mounting base plate 710. Transverse support rods 703 are disposed between the transverse support blocks 714 on the same side in the transverse direction. Two transverse sliding bearings 715 are sleeved on the outside of each transverse support rod 703. The transverse sliding bearings 715 are fixedly connected to the four corners of the transverse adjustment plate 711. A transverse movable top plate 702 is disposed on top of one of the transverse sliding bearings 715 in any transverse guide mechanism. A transverse adjuster 701 is also disposed on top of the transverse support block 714 adjacent to the transverse movable top plate 702. A spherical tip 713 is also disposed at the driving end of the transverse adjuster 701. The end of the spherical tip 713 is connected to the transverse movable top plate 702. A first rebound spring 704 is also disposed between the other transverse sliding bearing 715 and the adjacent transverse support block 714.

[0032] In the present invention, each longitudinal guide mechanism includes longitudinal support blocks 716 symmetrically arranged along the two longitudinal edges of the surface of the transverse adjustment plate 711. A longitudinal support rod 707 is disposed between the longitudinal support blocks 716 on the same side in the longitudinal direction. Two longitudinal sliding bearings 717 are sleeved on the outer side of each longitudinal support rod 707. The longitudinal sliding bearings 717 are fixedly connected to the four corners of the surface of the longitudinal adjustment plate 712. A longitudinal movable top plate 706 is disposed on top of one of the longitudinal sliding bearings 717 of any longitudinal guide mechanism. A longitudinal adjuster 705 is also disposed on top of the longitudinal support block 716 adjacent to the longitudinal movable top plate 706. A spherical tip 713 is also disposed on the driving end of the longitudinal adjuster 705. The end of the spherical tip 713 is connected to the longitudinal movable top plate 706. A second rebound spring 708 is also disposed between the other longitudinal sliding bearing 717 and the adjacent longitudinal support block 716.

[0033] In the present invention, the central axes of the measuring disk mounting seat 4, the spherical bearing 3 and the rotating measuring disk 2 are in the same straight line.

[0034] In the present invention, all parts are non-magnetic parts.

[0035] In use, the fixed mounting base 710 of the fine-tuning positioning device 7 is first fixedly connected to the axial ends of the outer chamber of the superconducting magnet 5 via pins. The longitudinal adjustment plates 712 of the fine-tuning positioning device 7 at both ends are then fixedly connected to the radial adjustment flanges 6 via pins and screws, respectively. A magnetic disc mount 4 is then installed at the proximal end of the radial adjustment flanges 6. The magnetic disc mount 4 is inserted into the inner diameter of the radial adjustment flange 6 to ensure concentricity between the two. A rotating magnetic disc 2 is maintained concentrically with the magnetic disc mount 4 via a spherical bearing 3. A rotating drive rod 1 is also provided between the two rotating magnetic discs 2. Radial Hall probes 9 are connected to the surfaces of the magnetic disc mounts 4 via radial probe mounts 8. The radial Hall probes 9 are positioned at the axial ends of the outer chamber of the superconducting magnet 5. Rotation of the drive rod 1 drives the radial Hall probes 9 to rotate along their axis, measuring the magnetic field at multiple radial locations on the ends of the superconducting magnet 5. The offset between the magnetic field center and the center of the radial adjustment flange 6 is calculated. Finally, the center of the magnetic field center and the center of the radial adjustment flange 6 are adjusted by fine-tuning the positioning device 7, so that the center heights of the two are finally coincident.

[0036] During adjustment, according to the calculated center offset data of the magnetic field center and the radial adjustment flange 6, it is selected to rotate the transverse adjuster 701 or the longitudinal adjuster 705. Taking the transverse adjuster 701 as an example, during adjustment, the transverse adjuster 701 is rotated in the forward direction so that the spherical top 713 at its driving end pushes the transverse movable top plate 702, thereby driving the transverse sliding bearing 715 connected to the transverse movable top plate 702 to move transversely along the transverse support rod 703 between the transverse support blocks 714 on the surface of the fixed installation base plate 710. Because the transverse sliding bearing 715 is fixedly connected to the four corners of the surface of the transverse adjustment plate 711, when one transverse sliding bearing 715 moves, it will drive the remaining transverse sliding bearings 715 to move transversely along the transverse support rod 703 through the transverse adjustment plate 711, thereby achieving the effect of adjusting the transverse position of the transverse adjustment plate 711. At this time, the transverse adjustment plate 711 is adjusted in transverse position on the fixed installation base plate 710, thereby driving the longitudinal adjustment plate 712 and the radial adjustment flange 6 installed on the longitudinal adjustment plate 712 to adjust in transverse position. After adjusting the transverse adjustment plate 711 to the corresponding position, a locking wrench is inserted into the bearing seat outside the transverse sliding bearing 715 to lock it and fix the position of the transverse adjustment plate 711. Conversely, by rotating the transverse adjuster 701 in the opposite direction, the transverse movable top plate 702 is no longer pushed by the spherical tip 713, thereby driving the transverse adjustment plate 711 in the opposite direction under the action of the first rebound spring 704. Similarly, when adjusting the longitudinal adjustment plate 712, rotating the longitudinal adjuster 705 in the forward direction can achieve longitudinal movement of the longitudinal adjustment plate 712 along the longitudinal support rod 707. Rotating the longitudinal adjuster 705 in the reverse direction, in conjunction with the second rebound spring 708, can drive the longitudinal adjustment plate 712 to move in the opposite direction, thereby enabling the longitudinal adjustment plate 712 to drive the radial adjustment flange 6 mounted thereon to adjust its longitudinal position.
