Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary assembly of magnetic resonance systems, and specifically relates to a horizontal assembly tooling system for a split superconducting magnet coil assembly. Background Art

[0002] The traditional cylindrical superconducting coil assembly is composed of a single main coil assembly and two shielding coil assemblies as a whole. Its assembly process can be vertically assembled on an operating table, and the accuracy is easy to guarantee and the assembly difficulty is small. The so-called vertical assembly means that the axis is vertically assembled. After assembly, it is circumferentially symmetric, the overall rigidity is good, and when it is flipped into a horizontal position during general assembly, the force is uniform and there is no risk of damage. The split superconducting magnet coil assembly is mainly composed of two separated superconducting coil assemblies (each containing a main coil and a shielding coil) as shown in Figure 5 shown. The assembly difficulty is greater and the accuracy is difficult to control. If vertical assembly is adopted, due to the lack of circumferential symmetry, the overall rigidity is slightly poor, and there is a risk of damaging the magnet when flipping.

[0003] Therefore, we propose a horizontal assembly tooling system for a split superconducting magnet coil assembly, and adopt a horizontal assembly method to assemble the split superconducting magnet coil assembly. Content of the Utility Model

[0004] The purpose of the utility model is to provide a horizontal assembly tooling system for a split superconducting magnet coil assembly.

[0005] The technical problem solved by the utility model is: how to horizontally assemble a split superconducting magnet coil assembly, and solve the problem that the existing vertical assembly method leads to subsequent flipping and is prone to low safety due to insufficient stiffness.

[0006] The utility model can be realized by the following technical solutions: a horizontal assembly tooling system for a split superconducting magnet coil assembly, including a horizontal base plate and support frames symmetrically fixed on the surface of the horizontal base plate. Z-direction adjustment components fixed to the horizontal base plate are respectively arranged on the opposite sides of the two support frames, and Z-direction adjustment stoppers are symmetrically and fixedly connected to the opposite side surfaces of the two support frames. Inner limit stoppers are evenly installed on the opposite side surfaces of the two support frames;

[0007] X-direction adjustment components and rotation adjustment toolings are respectively and fixedly arranged at the two sides of the top of each support frame.

[0008] A further technical improvement of the utility model lies in: two groups of tooling structure square tubes are arranged between the two support frames to connect the two support frames into a rigid whole.

[0009] A further technical improvement of the present utility model lies in that: a semi-circular groove is formed at the top of each support frame, a contact boss is fixed at the center position of the semi-circular groove, and the top surface of the contact boss is set as an arc surface to form a Y-direction support for the split superconducting magnet coil assembly.

[0010] A further technical improvement of the present utility model lies in that: the contact boss is made of nylon material with self-lubricating function.

[0011] A further technical improvement of the present utility model lies in that: the structural composition of the Z-direction adjustment component and the X-direction adjustment component both includes a fixed frame and a threaded rod threadedly connected to the fixed frame, and an abutting block is fixedly installed at one end of the threaded rod close to the split superconducting magnet coil assembly.

[0012] A further technical improvement of the present utility model lies in that: the rotation adjustment tooling includes a jack and a clamping block fixedly installed at the output end of the jack, and the clamping block abuts against the split superconducting magnet coil assembly.

[0013] A further technical improvement of the present utility model lies in that: bridge plate support blocks are symmetrically and fixedly installed on the opposite sides of the two support frames, and the horizontal height of each bridge plate support block is lower than the installation height of the contact boss.

[0014] A further technical improvement of the present utility model lies in that: a flange is coaxially fixed to the outside of each split superconducting magnet coil assembly by screws, a shaft core is coaxially penetrated between the two flanges, and axial and radial limits are carried out between the shaft core and the flange by positioning pins.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] By setting the X-direction adjustment component, the Z-direction adjustment component and the contact boss, the present utility model realizes the translational degrees of freedom of the split superconducting magnet coil assembly in three directions and two rotational degrees of freedom around the Y and Z axes, and can finely adjust the relative positions of the two split superconducting magnet coil assemblies, with high flexibility; in addition, by cooperating with the X-direction adjustment component and the rotation adjustment tooling, the split superconducting magnet coil assembly can be rotated around the Z axis, so as to correct the angular deviation between the two split superconducting magnet coil assemblies, further improving the assembly accuracy; in short, the entire assembly tooling system has the advantages of simple structure, low cost, high assembly accuracy and convenient use.

Detailed implementation manners

[0024] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and effects thereof according to the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figure 1-2 As shown, a horizontal assembly tooling system for a split superconducting magnet coil assembly includes a horizontal substrate 1 horizontally fixed on the ground. Two semi-circular support frames 2 are symmetrically fixed on the top of the horizontal substrate 1. Two sets of tooling structure square tubes 3 are used to fix between the two support frames 2, and the fixing methods include welding or screw connection, so that the two support frames 2 form a highly rigid whole. A contact boss 5 is fixedly arranged at the center of the semi-circular groove of each support frame 2 for supporting the corresponding split superconducting magnet coil assembly;

[0027] It should be noted that the top surface of the contact boss 5 is set as an arc surface. The main function of the contact boss 5 is to limit the freedom degree of the split superconducting magnet coil assembly in the longitudinal direction (i.e., the Y direction). Although theoretically the contact boss 5 with an arc surface can also limit the rotation of the split superconducting magnet coil assembly, due to the small surface contact area of the contact boss 5 and the relatively large radius of the arc of the arc surface, the surface tends to be flat, and in the actual assembly process, it is more similar to the contact effect of a plane, so only one degree of freedom is limited;

[0028] Furthermore, the contact boss 5 is made of nylon material. The nylon material has a self-lubricating function and a small friction coefficient, which is more conducive to any fine adjustment operation.

[0029] On the opposite sides of the two support frames 2, two Z-direction adjustment components 6 are symmetrically arranged. The two Z-direction adjustment components 6 are fixedly installed on the horizontal base plate 1. The Z-direction adjustment component 6 includes a fixed frame and a threaded rod threadedly connected to the fixed frame. On the side of the threaded rod close to the support frame 2, an abutting block is fixedly installed. At the same time, Z-direction adjustment stoppers 8 are symmetrically fixed on the opposite sides of the two support frames 2, and a plurality of inner limiting stoppers 10 are evenly arranged on the opposite sides of the two support frames 2. The Z-direction adjustment stopper 8, the Z-direction adjustment component 6 and the inner limiting stopper 10 cooperate to limit the Z-direction degree of freedom of the split superconducting magnet coil assembly. It should be noted that the inner limiting stopper 10 and the support frame 2 are set in a detachable connection manner, specifically a screw connection, which is convenient for finally removing the assembled superconducting magnet coil assembly.

[0030] On the top positions on both sides of each support frame 2, an X-direction adjustment component 4 and a rotation adjustment tooling 7 are fixedly installed respectively. The X-direction adjustment component 4 is similar to the Z-direction adjustment component 6, including a fixed frame and a threaded rod threadedly connected to the fixed frame. At one end of the threaded rod close to the semi-circular groove of the support frame 2, an abutting block is fixed.

[0031] The X-direction adjustment component 4 finely adjusts the X-direction deviation of the split superconducting coil assembly, thereby limiting the X-direction degree of freedom.

[0032] The rotation adjustment tooling 7 includes a jack and a clamping block fixedly installed at the output end of the jack. The clamping block abuts against the split superconducting coil assembly. When there is an angular deviation between the two split superconducting coil assemblies of the two support frames 2, the jack jacks up, and the clamping block jacks up the corresponding split superconducting coil assembly. Under the action of its own weight, the split superconducting coil assembly will rotate around the Z-axis to correct the angular deviation between the two.

[0033] On the opposite sides of the two support frames 2, bridge plate support blocks 9 are symmetrically and fixedly installed. The horizontal height of each bridge plate support block 9 is lower than the installation height of the contact boss 5.

[0034] When the utility model is in use, a hoisting crane is used to transport a separated superconducting magnet coil assembly to the corresponding support frame 2 and place it on the surface of the contact boss 5. Subsequently, the separated superconducting magnet coil assembly is adjusted to a proper position through the Z-direction adjusting assembly 6 and the Z-direction adjusting stop block 8, that is, it contacts the inner limiting stop block 10. Then, a bridging plate is placed on two bridging plate support blocks 9, and one end of the bridging plate is pre-assembled with the corresponding coil assembly. Then, the hoisting crane is used to transport another separated superconducting magnet coil assembly to the corresponding support frame 2 and place it on the surface of the contact boss 5. Subsequently, the separated superconducting magnet coil assembly is adjusted to contact the inner limiting stop block 10 through the Z-direction adjusting assembly 6 and the Z-direction adjusting stop block 8. Then, through the cooperation of the X-direction adjusting assembly 4 and the rotating adjusting tooling 7, the two separated superconducting magnet coil assemblies are coaxially arranged, and the angular deviation between the two is corrected. Finally, the upper and lower bridging plates are installed and fastened to complete the entire assembly process.

[0035] Embodiment 2

[0036] As Figure 3-4 shown, on the basis of Embodiment 1, in order to facilitate the hoisting and transportation of the assembled superconducting magnet coil assembly, flange plates 11 are coaxially arranged on the opposite sides of the two separated superconducting magnet coil assemblies located on the two support frames 2. The flange plates 11 are fixed to the end plates of the coil assemblies. An axle core 12 is coaxially penetrated between the two flange plates 11. The axial and radial limits between the axle core 12 and the flange plates 11 are carried out through positioning pins. When hoisting and transportation are required, the presence of the flange plates 11 and the axle core 12 increases the overall rigidity of the superconducting magnet coil assembly and has higher safety.

[0037] The above is only the preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to be equivalent embodiments with equivalent changes within the scope of the technical solution of the present utility model. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
