Description

Technical Field

[0001] The present invention relates to the technical field of superconducting magnets, and specifically to a fine-tuning positioning device for a superconducting magnet regulating flange of a high-precision magnetic axis gyrotron. Background Technique

[0002] Due to the requirements of high-precision axial magnetic field configuration during the use of superconducting magnets for gyrotrons and the requirement that the axis of the virtual room-temperature hole formed by the inner diameters of the upper and lower radial regulating flanges coincides highly with the magnetic field axis, it is often necessary to perform high-precision fine-tuning operations on the upper and lower radial regulating flanges of the magnet during the magnet testing stage, so that the axis of the virtual room-temperature hole formed by the inner diameters of the upper and lower radial regulating flanges of the magnet is coaxial with the axial magnetic field of the magnet with a superiority of better than 0.1, to ensure that the axis of the ion emitter can coincide highly with the magnetic field center of the superconducting magnet for the gyrotron during subsequent installation.

[0003] Currently, during the adjustment process of the upper and lower radial regulating flanges of the superconducting magnet, it is necessary to use a radial magnetic measurement device to test 8 points of the radial magnetic field, and a non-magnetic material wrench is required to rotate the four setscrews installed on the regulating flange to drive the regulating flange to move. This method cannot accurately grasp the moving distance and the final position of the regulating flange, relying entirely on the experience of the debugging personnel. Each time, it is necessary to go through the three steps of magnetic measurement - calculation - adjustment. When adjusting again, at least two mutually perpendicular setscrews need to be loosened, and then the setscrews are rotated to adjust the regulating flange. In this way, it cannot be guaranteed that the next adjustment effect will definitely be better than the previous one. Although the structure of the existing adjustment tooling is relatively simple, the operation process is more cumbersome, the operation process is relatively long, and there may be certain contingency in the adjustment process, and it is impossible to perform rapid and precise adjustment on the regulating flange, seriously affecting the subsequent axial magnetic field configuration test process.

[0004] Therefore, we will propose a fine-tuning positioning device for a superconducting magnet regulating flange of a high-precision magnetic axis gyrotron to improve the adjustment efficiency and accuracy of the axis of the virtual room-temperature hole formed by the radial regulating flange to be adapted and coaxial with the magnetic axis. Summary of the Invention

[0005] The purpose of the present invention is to provide a fine-tuning positioning device for a superconducting magnet regulating flange of a high-precision magnetic axis gyrotron to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A fine-tuning positioning device for a superconducting magnet regulating flange of a high-precision magnetic axis gyrotron, comprising a superconducting magnet. Fine-tuning positioning devices are respectively arranged at both axial ends of the outer dewar of the superconducting magnet. Radial regulating flanges are arranged between the fine-tuning positioning devices and the outer dewar of the superconducting magnet. Disk mounting seats for measurement are arranged on the inner sides of the radial regulating flanges. A spherical center bearing is arranged at the center of the surface of the disk mounting seat for measurement. A rotating measurement disk is arranged outside the spherical center bearing. A rotating drive rod penetrates between the two rotating measurement disks. The surface of the disk mounting seat for measurement is connected with a radial Hall probe through a radial probe mounting seat, and the radial Hall probe is arranged at both axial ends of the outer dewar of the superconducting magnet.

[0007] Further preferably, the fine-tuning positioning device includes a fixed mounting base plate fixedly connected to both axial ends of the outer dewar of the superconducting magnet through pins. Transverse guiding mechanisms are symmetrically arranged along the transverse direction at the edges of the surface of the fixed mounting base plate. One end of one of the transverse guiding mechanisms is connected with a transverse regulator. A transverse adjusting plate is movably connected between the transverse guiding mechanism and the fixed mounting base plate. Longitudinal guiding mechanisms are symmetrically arranged along the longitudinal direction at the edges of the surface of the transverse adjusting plate. One end of one of the longitudinal guiding mechanisms is connected with a longitudinal regulator. A longitudinal adjusting plate is movably connected between the longitudinal guiding mechanism and the transverse adjusting plate.

[0008] Further preferably, each of the transverse guiding mechanisms includes transverse support blocks symmetrically arranged along two transverse edges of the surface of the fixed mounting base plate. Transverse support rods are arranged between the transverse support blocks on the same side in the transverse direction. Two transverse sliding bearings are sleeved outside each transverse support rod. The transverse sliding bearings are fixedly connected to the four corners of the surface of the transverse adjusting plate.

[0009] Further preferably, a transverse moving top plate is arranged at the top of one of the transverse sliding bearings of any one of the transverse guiding mechanisms. A transverse regulator is also arranged at the top of the transverse support block close to the transverse moving top plate. A spherical tip is arranged at the driving end of the transverse regulator. The end of the spherical tip is connected to the transverse moving top plate. A first return spring is also arranged between the other transverse sliding bearing and the adjacent transverse support block.

[0010] Further preferably, each of the longitudinal guiding mechanisms includes longitudinal support blocks symmetrically arranged along two longitudinal edges of the surface of the transverse adjusting plate. Longitudinal support rods are arranged between the longitudinal support blocks on the same side in the longitudinal direction. Two longitudinal sliding bearings are sleeved outside each longitudinal support rod. The longitudinal sliding bearings are fixedly connected to the four corners of the surface of the longitudinal adjusting plate.

[0011] Further preferably, a longitudinal moving top plate is provided at the top of one of the longitudinal sliding bearings of any one of the longitudinal guiding mechanisms. A longitudinal regulator is further provided at the top of the longitudinal support block close to the longitudinal moving top plate. A spherical tip is further provided at the driving end of the longitudinal regulator. The end of the spherical tip is connected to the longitudinal moving top plate. A second return spring is further provided between the longitudinal support block adjacent to the other longitudinal sliding bearing.

[0012] Further preferably, the central axes of the measuring disk mounting seat, the spherical center bearing and the rotating measuring disk are on the same straight line.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: By utilizing the reverse pushing actions of the transverse regulator, the longitudinal regulator, the first return spring and the second return spring, the transverse adjusting plate and the longitudinal adjusting plate can be moved back and forth along the transverse and longitudinal directions by manually rotating the transverse regulator or the longitudinal regulator clockwise or counterclockwise. This design has the characteristics of simple operation and simple structure, and can accurately judge the positions of the moved transverse adjusting plate and longitudinal adjusting plate in the transverse and longitudinal directions.

[0014] The fine-tuning positioning device and the rotating measuring disk are simultaneously and fixedly installed on the radial adjusting flange, so that the rotating measuring disk can synchronously measure the magnetic field measurement center after the radial adjusting flange is driven by the fine-tuning positioning device, avoiding the deviation of the magnetic field centers measured successively due to the disassembly of components, and improving the measurement accuracy and reliability of the magnetic field center positions at the upper and lower radial adjusting flanges.

[0015] The application of the rotary drive rod and the spherical center bearing can not only drive the two rotating measuring disks to rotate for magnetic field measurement simultaneously, but also avoid the jamming of the measuring disk during rotation due to the non-perpendicularity of the rotary drive rod and the end face of the radial adjusting flange. While ensuring that the rotating measuring disk is always in a horizontal state, it can also ensure the smooth operation of the rotating measuring disk during rotation, greatly improving the magnetic field measurement efficiency.

[0016] In summary, the device can accurately adjust the concentricity between the virtual axis center formed by the two radial adjusting flanges and the measuring magnetic field axis, improving and reducing the difficulty of the concentricity adjustment process, shortening the adjustment time, reducing a lot of manual repetitive labor, and is especially applicable to superconducting magnets for gyrotrons with high coaxiality requirements.

[0022] In the present invention, each of the longitudinal guiding mechanisms includes longitudinal support blocks 716 symmetrically arranged along two longitudinal edges of the surface of the transverse adjusting plate 711.

A second return spring 708 is also arranged between the other longitudinal sliding bearing 717 and the adjacent longitudinal support block 716.

[0023] In the present invention, the central axes of the measuring disk mounting seat 4, the spherical center bearing 3, and the rotating measuring disk 2 are on the same straight line.

[0024] In the present invention, all parts are non-magnetic parts.

[0025] Embodiment: When in use, first, the fixed mounting base plate 710 of the fine-tuning positioning device 7 is fixedly connected to the axial ends of the outer dewar of the superconducting magnet 5 through pins. Then, radial adjustment flanges 6 are fixedly connected to the surfaces of the longitudinal adjustment plates 712 of the two fine-tuning positioning devices 7 at both ends through pins and screws. Next, a disk measuring base 4 is installed at one end where the radial adjustment flanges 6 are close to each other. The disk measuring base 4 is inserted into the inner diameter of the radial adjustment flange 6 to ensure concentricity between the two. The rotating disk 2 is concentric with the disk measuring base 4 through a spherical center bearing 3. A rotating drive rod 1 is also arranged through the two rotating disks 2. A radial Hall probe 9 is connected to the surface of the disk measuring base 4 through a radial probe mounting base 8, and the radial Hall probe 9 is arranged at the axial ends of the outer dewar of the superconducting magnet 5. By rotating the rotating drive rod 1, the radial Hall probe 9 is driven to rotate along the axis, the magnetic fields at multiple positions in the radial direction of the end of the superconducting magnet 5 are measured, and the offset between the magnetic field center and the center of the radial adjustment flange 6 is calculated. Finally, the fine-tuning positioning device 7 is used to adjust the centrality between the magnetic field center and the radial adjustment flange 6, so that the central heights of the two finally coincide.

[0026] During adjustment, based on the calculated offset data between the magnetic field center and the center of the radial adjustment flange 6, select whether to rotate the transverse adjuster 701 or the longitudinal adjuster 705. Taking the transverse adjuster 701 as an example, during adjustment, by rotating the transverse adjuster 701 forward, the spherical tip 713 at its driving end pushes the transverse moving top plate 702, thereby driving the transverse sliding bearing 715 connected to the transverse moving top plate 702 to move horizontally along the transverse support rod 703 between the transverse support blocks 714 on the surface of the fixed mounting base plate 710. Since 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 horizontally along the transverse support rod 703 through the transverse adjustment plate 711, thereby achieving the effect of adjusting the horizontal position of the transverse adjustment plate 711. At this time, the transverse adjustment plate 711 adjusts its horizontal position on the fixed mounting base plate 710, and then drives the longitudinal adjustment plate 712 and the radial adjustment flange 6 installed on the longitudinal adjustment plate 712 to adjust their horizontal positions. And after adjusting the transverse adjustment plate 711 to the corresponding position, insert the locking wrench into the inner part of the bearing seat outside the transverse sliding bearing 715 to lock it and fix the position of the transverse adjustment plate 711. On the contrary, by rotating the transverse adjuster 701 in the reverse direction, the transverse moving top plate 702 is no longer pushed by the spherical tip 713, so that under the action of the first return spring 704, the transverse adjustment plate 711 is driven to move in the opposite direction. Similarly, when adjusting the longitudinal adjustment plate 712, rotating the longitudinal adjuster 705 forward can also achieve the longitudinal movement of the longitudinal adjustment plate 712 along the longitudinal support rod 707. Rotating the longitudinal adjuster 705 in the reverse direction, in cooperation with the second return spring 708, can drive the longitudinal adjustment plate 712 to move in the opposite direction, and then achieve the longitudinal position adjustment of the radial adjustment flange 6 installed on the longitudinal adjustment plate 712.
