[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 4 An assembly tool 100 for a fusion device Dewar bellows according to an embodiment of the present invention is described.

[0034] like Figure 1 and Figure 2 As shown, an assembly tool 100 for a Dewar bellows of a fusion device according to an embodiment of the present invention comprises: a guide beam 10 , an adjustment assembly 20 and a support frame 30 .

[0035] Specifically, the guide beam 10 is moved along a first direction (eg Figure 2 The adjusting assembly 20 is arranged on the guide beam 10, the support frame 30 is annular and sleeved on the adjusting assembly 20, the guide beam 10 is arranged on the radial inner side of the support frame 30, the support frame 30 is used to support the Dewar bellows 220, and the adjusting assembly 20 is configured to drive the support frame 30 relative to the guide beam 10 in the first direction and the second direction (for example Figure 2 ) and a third direction (e.g. Figure 2 The support frame 30 is configured to move in the up and down directions shown in the figure, and is used to drive the support frame 30 to rotate around the guide beam 10, and the first direction, the second direction and the third direction intersect with each other.

[0036] In the process of assembling the Dewar bellows 220 onto the nuclear fusion device 200, the Dewar bellows 220 is first sleeved on the support frame 30, and then the support frame 30 is sleeved on the adjustment component 20, and then the Dewar bellows 220 is extended into the assembly channel through the guide beam 10, and then the relative position of the support frame 30 relative to the guide beam 10 in the first direction, the second direction and the third direction, and the angle of the support frame 30 guide beam 10 are adjusted through the adjustment component 20, so that the relative position and angle of the Dewar bellows 220 and the assembly channel can be adjusted.

[0037] Therefore, during the assembly process of the Dewar bellows 220, the difficulty of adjusting the position and angle of the Dewar bellows 220 can be reduced. At the same time, in some smaller assembly spaces, compared with adjusting the position and angle of the suspended Dewar bellows 220 in the prior art, adjusting the position and angle of the Dewar bellows 220 by operating the adjustment component 20 is less constrained by the assembly space.

[0038] Among them, the assembly channel can be a channel connecting the biological shielding layer window 210 and the Dewar window, and the assembly channel can also be a channel connecting the Dewar window and the vacuum chamber window. A driving component can be set on the adjustment component 20 to adjust the position and angle of the Dewar bellows 220, and the adjustment component 20 can also be manually operated to adjust the position and angle of the Dewar bellows 220.

[0039] According to the assembly tool 100 for the Dewar bellows of a fusion device according to the embodiment of the present invention, during the assembly process of the Dewar bellows 220, the position and angle of the Dewar bellows 220 can be adjusted, and the degree of constraint by the assembly space during the adjustment process is low, thereby reducing the assembly difficulty of the Dewar bellows 220 and improving the assembly accuracy of the Dewar bellows 220.

[0040] In some embodiments of the present invention, Figure 3 and Figure 4As shown, the adjustment component 20 includes: a first load-bearing member 21, one of the first load-bearing member 21 and the guide beam 10 is provided with a first guide rail 11, and the other is provided with a first slider 211, the first guide rail 11 extends along a first direction, the first slider 211 is movably matched with the first guide rail 11 along the first direction, and the support frame 30 is supported on the first load-bearing member 21. Therefore, during the assembly process of the Dewar bellows 220, the first slider 211 moves along the first direction on the first guide rail 11, so that the support frame 30 can drive the Dewar bellows 220 to move in the first direction, thereby adjusting the position of the Dewar bellows 220 in the first direction, and the structure of the first guide rail 11 and the first slider 211 are relatively simple, which can reduce the design difficulty of the adjustment component 20.

[0041] Among them, preferably, the support frame 30 is supported on the first load-bearing member 21 through the adjustment bracket 23, the third driving member 231 and the second load-bearing member 22 in sequence. Specifically, the support frame 30 is supported on the adjustment bracket 23, the adjustment bracket 23 is supported on the second load-bearing member 22 through the third driving member 231, and the second load-bearing member 22 is supported on the first load-bearing member 21.

[0042] Preferably, two limit blocks 12 arranged at intervals in the first direction are provided on the guide beam 10, and the first load-bearing member 21 moves between the two limit blocks 12. In this way, the limit blocks 12 can limit the displacement path of the first load-bearing member 21 to prevent the first load-bearing member 21 from slipping off the guide beam 10.

[0043] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the adjustment assembly 20 further includes: a first driving member 212 that is retractable in the first direction, and the first driving member 212 is connected between the first load-bearing member 21 and the guide beam 10 to drive the first load-bearing member 21 to move in the first direction relative to the guide beam 10. Thus, the difficulty of adjusting the position of the Dewar bellows 220 in the first direction can be reduced, and the accuracy of adjusting the position of the Dewar bellows 220 in the first direction can be improved. Preferably, the first driving member 212 is a hydraulic push rod, and the adjustment accuracy of the first driving member 212 is ±0.5 mm.

[0044] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the first load-bearing member 21 is formed with a guide groove 214 which penetrates the first load-bearing member 21 in a first direction, the guide beam 10 is arranged in the guide groove 214, and a plurality of first guide rails 11 are arranged in the circumferential direction of the guide beam 10, for example, the first guide rails 11 may be two or four, and a plurality of first sliders 211 are arranged on the inner wall of the guide groove 214, and the plurality of first sliders 211 are respectively connected to the plurality of first guide rails 11.

[0045] Among them, preferably, a plurality of first sliders 211 are connected to a first guide rail 11, so that each group of first sliders 211 and the first guide rail 11 can cooperate to guide and support the first load-bearing member 21, and the first sliders 211 are more evenly distributed on the first load-bearing member 21, and the supporting force of the guide beam 10 on the first load-bearing member 21 is more evenly distributed, thereby improving the stability of the movement of the first load-bearing member 21 on the guide beam 10 and the reliability of the connection.

[0046] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the adjustment assembly 20 also includes: a second load-bearing member 22, one of the first load-bearing member 21 and the second load-bearing member 22 is provided with a second guide rail 213, and the other is provided with a second slider 221, the second guide rail 213 extends along the second direction, the second slider 221 is movably engaged with the second guide rail 213 along the second direction, and the support frame 30 is supported on the second load-bearing member 22.

[0047] Therefore, during the assembly of the Dewar bellows 220, the second slider 221 moves along the second direction on the second guide rail 213, so that the second load-bearing member 22 can move in the second direction, and then the support frame 30 drives the Dewar bellows 220 to move in the second direction, thereby realizing the adjustment of the position of the Dewar bellows 220 in the second direction, and the structure of the cooperation between the second guide rail 213 and the second slider 221 is relatively simple, which can reduce the design difficulty of the adjustment component 20.

[0048] The support frame 30 is supported on the first load-bearing member 21 through the second load-bearing member 22. When the first load-bearing member 21 moves in the first direction relative to the guide beam 10, the first load-bearing member 21 can drive the second load-bearing member 22 to move in the first direction, thereby driving the support frame 30 and the Dewar bellows 220 to move in the first direction. Preferably, the support frame 30 is supported on the second load-bearing member 22 through the adjustment bracket 23 and the third driving member 231.

[0049] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the adjustment assembly 20 further includes: a second driving member 222 that is retractable in the second direction, and the second driving member 222 is connected between the first load-bearing member 21 and the second load-bearing member 22 to drive the second load-bearing member 22 to move in the second direction relative to the first load-bearing member 21. Thus, the difficulty of adjusting the position of the Dewar bellows 220 in the second direction can be reduced, and the accuracy of adjusting the position of the Dewar bellows 220 in the second direction can be improved. Preferably, the second driving member 222 is a hydraulic push rod, and the adjustment accuracy of the second driving member 222 is ±0.5mm.

[0050] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the adjustment assembly 20 also includes; an adjustment bracket 23 and a third driving member 231, the third driving member 231 is retractable in the third direction, the third driving member 231 is connected between the adjustment bracket 23 and the second load-bearing member 22 to drive the adjustment bracket 23 to move in the third direction relative to the second load-bearing member 22, and the support frame 30 is supported on the adjustment bracket 23.

[0051] Thus, during the assembly of the Dewar bellows 220, the third driving member 231 drives the adjustment bracket to move in the third direction, so that the support frame 30 can drive the Dewar bellows 220 to move in the third direction, thereby adjusting the position of the Dewar bellows 220 in the third direction. Among them, by providing the third driving member 231, the difficulty of adjusting the position of the Dewar bellows 220 in the third direction can be reduced, and the accuracy of adjusting the position of the Dewar bellows 220 in the third direction can be improved. Preferably, the third driving member 231 is a hydraulic push rod, and the adjustment accuracy of the third driving member 231 is ±0.5mm. The adjustment bracket 23 is provided with a support plate 233, and the third driving member 231 is connected to the support plate 233.

[0052] Among them, the support frame 30 is supported on the first load-bearing member 21 through the adjustment bracket 23 and the second load-bearing member 22. When the first load-bearing member 21 moves in the first direction and the second load-bearing member 22 moves in the second direction, the adjustment bracket 23 drives the support frame 30 and the Dewar bellows 220 to move synchronously.

[0053] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the third driving member 231 is rotatably connected to the adjusting bracket 23, the second load-bearing member 22 is provided with a first connecting portion 223, the adjusting bracket 23 is provided with a second connecting portion 232, the first connecting portion 223 and the second connecting portion 232 are arranged at intervals in the second direction, and the adjusting assembly 20 also includes: a fourth driving member 234 which is retractable along the length direction, and the fourth driving member 234 is connected between the first connecting portion 223 and the second connecting portion 232 to drive the adjusting bracket 23 to rotate relative to the third driving member 231.

[0054] During the assembly of the Dewar bellows 220, when the angle of the Dewar bellows 220 needs to be fixed, the fourth driving member 234 can provide support between the first connecting portion 223 and the second connecting portion 232, so that the Dewar bellows 220 does not rotate relative to the third driving member 231. When the angle of the Dewar bellows 220 needs to be adjusted, the fourth driving member 234 is extended and retracted, thereby driving the adjustment bracket 23 to rotate relative to the third driving member 231. As a result, the support frame 30 can be rotated around the guide beam 10, thereby realizing the adjustment of the angle of the Dewar bellows 220.

[0055] By providing the fourth driving member 234, the difficulty of adjusting the angle of the Dewar bellows 220 can be reduced, and the accuracy of adjusting the angle of the Dewar bellows 220 can be improved. Preferably, the fourth driving member 234 is a hydraulic push rod, and the adjustment accuracy of the fourth driving member 234 is ±0.5mm. The third driving member 231 and the adjustment bracket 23 are rotatably connected through a joint bearing.

[0056] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, both the first connection part 223 and the second connection part 232 are multiple and correspond one to one. For example, the first connection part 223 can be four, six or eight, and the multiple fourth driving members 234 are respectively arranged on both sides of the third driving member 231 in the second direction. In this way, when the angle of the Dewar bellows 220 needs to be fixed, the fourth driving member 234 can support the adjustment bracket 23 on both sides of the third driving member 231, thereby improving the stability of the adjustment bracket. When the angle of the Dewar bellows 220 needs to be adjusted, the fourth driving member 234 on one side of the third driving member 231 is extended, and the fourth driving member 234 on the other side is contracted. In this way, the stability and accuracy of the Dewar bellows 220 during the angle adjustment process can be improved.

[0057] In some embodiments of the present invention, Figure 2 As shown, the assembly tool 100 for the Dewar bellows of the fusion device also includes: a support frame 40 and a support rail 41, a guide beam 10 is fixed on the support frame 40, one end of the guide beam 10 provided with the adjustment assembly 20 extends out of the support frame 40 in the first direction, and the support frame 40 is movably arranged on the support rail 41 along the first direction. During the assembly of the Dewar bellows 220, the support frame 40 and the support rail 41 are moved to the set position, and then the support frame 40 is moved in the first direction, and the support frame 30 and the Dewar bellows 220 are extended into the assembly channel through the guide beam 10, so that it is relatively easy to move the guide beam 10, which can further reduce the difficulty of operation during the assembly of the Dewar bellows 220.

[0058] Preferably, a frame slider 42 is provided at the lower side of the support frame 40 , and the support frame 40 is movably disposed on the support rail 41 along the first direction via the frame slider 42 .

[0059] In some embodiments of the present invention, Figure 2As shown, the assembly tool 100 for the Dewar bellows of the fusion device also includes: a counterweight 50, which is connected to the support frame 40. It can be understood that the guide beam 10 extends out of the support frame 40, and the center of gravity of the adjustment assembly 20, the support frame 30 and the Dewar bellows 220 is located outside the support frame 40. The gravity of the above components acts on the support frame 40 to generate a rotational torque, which affects the stability and reliability of the support frame 40. By setting the counterweight 50, the torque generated by the gravity of the counterweight 50 can offset the above rotational torque, thereby improving the stability of the Dewar bellows 220 during the assembly process and the reliability of the support frame 40 supporting the guide beam 10.

The counterweight 50 is connected to the second support beam 61 through the pull rod 62, and the counterweight 50 is located below the guide beam 10. In this way, the connection between the counterweight 50 and the support frame 40 can be achieved. Preferably, there are two first support beams 60 and two second support beams 61. The second support beam 61 is arranged above the guide beam 10. A plurality of hydraulic rods are arranged between the first support beam 60 and the support frame 40. The plurality of hydraulic rods are used to adjust the support height of the first support beam 60, so as to achieve leveling of the support surface of the first support beam 60.
