Description

Technical Field

[0001] The invention relates to the technical field of superconducting magnets, in particular to a superconducting magnet assembly positioning structure. Background Art

[0002] Superconducting magnet refers to an electromagnet made of a coil made of a second-class superconductor with a high transition temperature and a particularly high critical magnetic field at low temperature. Its main feature is that there is no electrical loss caused by wire resistance, and there is no magnetic loss caused by the existence of the iron core, which has a strong practical value. It is widely used in industry and scientific research, but it must work at liquid helium temperature and is relatively expensive.

[0003] After the superconducting magnet is produced, it needs to be subsequently processed, assembled or tested. At the same time, the superconducting magnet needs to be fixed and limited by equipment. However, the existing superconducting magnet is directly positioned by clamping during assembly. When the clamping tool is subjected to excessive force, the clamping head is likely to damage the superconducting magnet. Secondly, this positioning method is likely to cause the superconducting magnet to fall off the positioning mechanism during subsequent operations. Summary of the invention

[0014] Beneficial effects:

[0015] Compared with the prior art, this superconducting magnet assembly positioning structure has the following beneficial effects:

[0016] 1. The present invention provides a manual positioning mechanism. The handle is held and rotated by hand, and the connecting rod drives the transmission bevel gear to rotate. At this time, the main bevel gear drives the connecting shaft to rotate under the meshing action. At the same time, the pull rope and the surface of the connecting shaft continue to be entangled.

The reset spring is squeezed and contracted, and the handle is rotated in the opposite direction. At this time, the pull rope on the surface of the connecting shaft is relaxed, and the reset spring pushes the positioning bar to move to the initial position, which is conducive to quickly positioning the superconducting magnet and ensuring that the superconducting magnet is located in the middle of the operating table, thereby avoiding position deviation during subsequent processing or operation.

[0017] 2. The present invention provides an auxiliary limiting mechanism, which drives the movable shaft to slide toward the top of the connecting hole through the thread during the rotation of the connecting shaft. When the top of the movable shaft extends out of the connecting hole, the extrusion spring reacts on the limiting bar to move its top toward the outside of the placement groove, while supporting the inner ring of the superconducting magnet, which is beneficial to positioning the inner ring of the superconducting magnet and enhancing the positioning stability and accuracy.

[0026] like Figure 1-2 As shown, the manual positioning mechanism 5 includes a main bevel gear 501, a transmission bevel gear 502, a connecting rod 503, a handle 504, a pull rope 505, a positioning bar 506 and a reset spring 507. The handle 504 is fixedly connected to one end of the connecting rod 503, and the transmission bevel gear 502 is fixedly connected to the other end of the connecting rod 503. The main bevel gear 501 is meshed with the transmission bevel gear 502. There are four positioning bars 506. The two ends of the pull rope 505 are respectively fixedly connected to the bottom ends of the opposite sides of the mutually symmetrical positioning bars 506. The reset springs 507 are respectively It is fixedly connected to the inner side of the positioning bar 506, the top of the positioning bar 506 is arc-shaped, the bottom end of the positioning bar 506 passes through the connecting groove 3 and extends to its bottom end, the reset spring 507 is located inside the connecting groove 3, and the end of the reset spring 507 away from the positioning bar 506 is fixedly connected to the inner wall of the connecting groove 3, the middle position of the pull rope 505 is movably connected to the outer side of the connecting shaft 4 in a winding manner, the connecting shaft 4 passes through the axis of the main bevel gear 501 and is fixedly connected thereto, the connecting rod 503 passes through the base 1 and the connection is movably connected through a bearing.

[0027] By holding the handle and turning it, the connecting rod 503 drives the transmission bevel gear 502 to rotate. At this time, the main bevel gear 501 driven by the meshing action drives the connecting shaft 4 to rotate, and the pull rope 505 continues to be entangled with the surface of the connecting shaft 4. In this process, both ends of the pull rope 505 pull the positioning bar 506 inward to slide to the opposite side in the slide groove, and the reset spring 507 is squeezed and contracted, and the handle 504 is turned in the opposite direction. At this time, the pull rope 505 on the surface of the connecting shaft 4 is relaxed, and the reset spring 507 pushes the positioning bar 506 to move to the initial position, which is conducive to quickly positioning the superconducting magnet and ensuring that the superconducting magnet is located in the middle of the operating table 2, thereby avoiding position deviation during subsequent processing or operation.

[0028] like Figure 1 , Figure 3 and Figure 4As shown, the auxiliary limiting mechanism 7 includes a movable shaft 701, a squeezing spring 702 and a limiting strip 703. The movable shaft 701 is provided with placement grooves 704 all around. The limiting strip 703 is inclined and its bottom end is movably connected to the inner bottom end of the placement groove 704 through a rotating shaft. The squeezing spring 702 is located inside the placement groove 704. One end of the squeezing spring 702 is fixedly connected to the inner wall of the placement groove 704, and the other end of the squeezing spring 702 is fixedly connected to the inner side of the limiting strip 703. A thread is provided on the outer side of the movable shaft 701, and the movable shaft 701 is adapted to the connecting hole 6. A thread is provided inside the connecting hole 6, and the movable shaft 701 is movably connected to the inside of the connecting hole 6 through the thread.

[0029] During the rotation of the connecting shaft 4, the thread drives the moving shaft 701 to slide toward the top of the connecting hole 6. When the top of the moving shaft 701 extends out of the connecting hole 6, the squeezing spring 702 reacts on the limiting bar 703 to move the top of the moving shaft toward the outside of the placement groove 704, while supporting the inner ring of the superconducting magnet. This is conducive to positioning the inner ring of the superconducting magnet and enhancing positioning stability and accuracy.

[0030] Working principle: When in use, place the superconducting magnet on the surface of the operating table 2, then hold the handle and turn it, and the connecting rod 503 drives the transmission bevel gear 502 to rotate. At this time, the main bevel gear 501 drives the connecting shaft 4 to rotate under the meshing action, and the pull rope 505 continues to be entangled with the surface of the connecting shaft 4. During this process, both ends of the pull rope 505 pull the positioning bar 506 inward to slide to the opposite side in the slide groove, and the reset spring 507 is squeezed and contracted. Secondly, during the rotation of the connecting shaft 4, the moving shaft 701 is driven by the thread to slide toward the top of the connecting hole 6 When the top of the movable shaft 701 extends out of the connecting hole 6, the squeezing spring 702 reacts on the limiting bar 703 to make its top move toward the outside of the placement slot 704, while supporting the inner circle of the superconducting magnet. After the operation is completed, the handle 504 is rotated in the opposite direction. At this time, the pull rope 505 on the surface of the connecting shaft 4 is relaxed, and the reset spring 507 pushes the positioning bar 506 to move to the initial position, while the displacement rod slides toward the inside of the connecting hole 6. In this process, the limiting bar 703 is squeezed by the connecting hole 6, moves toward the inside of the placement slot 704, and squeezes the squeezing spring 702.
