Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fusion reactors, in particular to an assembly tool and an assembly method for a divertor. BACKGROUND

[0002] The divertor is one of the important components of a fusion device (for example, a common tokamak device). The divertor is generally divided into a target plate and a body according to its own function and structure. The target plate is a component that bears high heat load when the divertor faces the plasma, and the target plate includes an inner target plate, an outer target plate, and a DOME plate. The body is an important load-bearing component for supporting the target plate and transferring electromagnetic force. The common existing divertor usually adopts a box body (divertor box) as the body, the box body has an irregular shape, and the box body has an inner side surface and an outer side surface arranged oppositely; the inner target plate, the DOME plate, and the outer target plate are sequentially mounted to the inner side surface of the box body along the extension direction of the box body, and the box body is connected to the fusion device through the outer side surface thereof.

[0003] The inner target plate, the outer target plate, and the DOME plate are tungsten-copper assembly pieces with tungsten on the surface and cooling channels inside; when the fusion device is working, the target surface (i.e., the tungsten-coated surface) of the target plate directly faces the plasma, and the profile shape of the tungsten surface is directly related to the plasma discharge shape; therefore, it is necessary to ensure that the profile degree of the target surface of the target plate of the divertor is within the error allowable range, so as to effectively guarantee the normal work of the divertor.

[0004] However, in the existing assembly process of the box body and the target plate, there is a lack of an assembly tool that can serve as an assembly reference, which makes it difficult to determine a suitable reference for profile detection of the target plate after the target plate is mounted to the box body, thereby resulting in poor assembly precision and ultimately affecting the normal work of the divertor.

[0061] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0062] like Figures 1-3 As shown, an assembly fixture 2 for a divertor according to an embodiment of the present invention includes a reference component 21 and a positioning component 22.

[0063] The reference assembly 21 includes a first reference plate 211 and a second reference plate 212. The first reference plate 211 is horizontally arranged, and the second reference plate 212 is vertically arranged and fixedly connected to the first reference plate 211. The first reference plate 211 has a first reference surface 2101, and the second reference plate 212 has a second reference surface 2102 that is perpendicular to the first reference surface 2101.

[0064] The positioning component 22 includes a first positioning block 221, a second positioning block 222, and a third positioning block 223 arranged sequentially at intervals along the length of the first reference plate 211; the second positioning block 222 and the third positioning block 223 are fixed to the upper surface of the first reference plate 211, and the first positioning block 221 is fixed to the side surface of the second reference plate 212 opposite to the second positioning block 222; the side surface of the first positioning block 221 opposite to the second positioning block 222 defines a first positioning surface 2201, the upper surface of the second positioning block 222 defines a second positioning surface 2202, and the upper surface of the third positioning block 223 defines a third positioning surface 2203;

[0065] The first positioning surface 2201, the second positioning surface 2202, and the third positioning surface 2203 are respectively set to correspond one-to-one with the mounting surface of the divertor housing to the fusion device.

[0066] Based on the above technical solution, the first positioning surface 2201, the second positioning surface 2202, and the third positioning surface 2203 of the positioning component 22 facilitate the positioning and fixing of the divertor housing 11 to the assembly fixture 2, thereby facilitating the installation and fixing of the target plate 12 and the housing 11. The mutually perpendicular first reference surface 2101 and second reference surface 2102 allow for the establishment of a reference coordinate system during the assembly of the divertor housing and the target plate, and during the contour detection of the target plate. This facilitates the contour detection and adjustment of the target plate 12 using the reference coordinate system as a reference, ensuring that the contour of the target plate 12 in the divertor assembled using the assembly fixture 2 meets the allowable error, and thus guaranteeing that the divertor assembled using the assembly fixture 2 has sufficient assembly accuracy.

[0067] Preferably, such as Figures 1-3 As shown, in this embodiment, the upper surface of the first reference plate 211 defines a first reference surface 2101, and the side surface of the second reference plate 212 opposite to the second positioning block 222 defines a second reference surface 2102. The two mutually perpendicular reference surfaces can form a reference coordinate system after defining the origin, so as to detect the target plate 12.

[0068] Furthermore, such as Figures 1-3 As shown, the second reference plate 212 is provided with a first reinforcing rib 231 and a second reinforcing rib 232 on both sides of the first reference plate 211 along the length direction. The end of the second reinforcing rib 232 away from the second reference plate 212 is fixedly connected to the second positioning block 222. The first reinforcing rib 231 and the second reinforcing rib 232 are both fixedly connected to the first reference plate 211.

[0069] It can be understood that, since the second reference plate 212 is vertically arranged and fixedly connected to the first reference plate 211, in order to improve the reliability of the second reference plate 212 and prevent the reliability of the second reference surface 2102 from being damaged due to slight bending or tilting of the second reference plate 212, first and second reinforcing ribs 231 and 232 are arranged on the two side surfaces of the second reference plate 212 in the force direction, and the first and second reinforcing ribs 231 and 232 are used to transmit the force of the second reference plate 212 to the horizontally arranged first reference plate 211; and the second reinforcing rib 232 is also connected to the second positioning block 222, so as to guarantee the accuracy of the relative positions of the first and second positioning surfaces 2201 and 2202, provide a positioning assembly position with good accuracy for the box body 11, and help to improve the overall assembly accuracy of the filter 1.

[0070] Further, as shown in Figures 1-3 the third reinforcing rib 233 is fixedly arranged on the side of the second positioning block 222 away from the second reference plate 212, and the fourth and fifth reinforcing ribs 234 and 235 are fixedly arranged on the two sides of the third positioning block 223 in the length direction of the first reference plate 211.

[0071] The third, fourth and fifth reinforcing ribs 233, 234 and 235 are fixedly connected to the first reference plate 211.

[0072] It can be understood that the third reinforcing rib 233 is arranged to provide a reinforcing structure on the two sides of the second positioning block 222 in the length direction of the first reference plate 211, and the fourth and fifth reinforcing ribs 234 and 235 are arranged to provide a reinforcing structure on the two sides of the third positioning block 223 in the length direction of the first reference plate 211.

[0073] Further, as shown in Figure 3 the assembly tool 2 further comprises a compensation assembly 24.

[0074] The compensation assembly 24 is arranged above the third positioning block 223 and detachably connected to the third positioning block 223, and is used to form a fourth positioning surface 2204 arranged above the third positioning surface 2203.

[0075] It can be understood that the assembly of the deflector 1 includes the assembly of the box body 11 and the target plate 12 and the connection of the cooling flow channels in the target plate 12. Since the cooling flow channels are arranged in the interior of the target plate 12 and the water inlet and outlet and the target surface are located at opposite sides, the operation space for the connection of the cooling flow channels is small. By arranging the compensation assembly 24, the assembly tool 2 has the fourth positioning surface 2204 which is spaced above the third positioning surface 2203, so that the box body 11 can be lifted on the basis of the original position to reserve sufficient operation space.

[0076] Further, as shown in Figure 3 , the compensation assembly 24 is arranged; the compensation assembly 24 includes a compensation pipe 241 and a compensation plate 242;

[0077] The compensation pipe 241 is vertically arranged, and the compensation pipe 241 is fixedly provided with the compensation plate 242 at both ends;

[0078] The compensation pipe 241 is detachably connected with the third positioning block 223 through the compensation plate fixedly arranged at the bottom end of the compensation pipe 241; and the upper surface of the compensation plate fixedly arranged at the top end of the compensation pipe 241 defines the fourth positioning surface 2204.

[0079] Preferably, the balance of the assembly tool 2 as a whole is better, so as to avoid the lateral overturning of the box body 11 and the target plate 12 with certain weight and size during the assembly process due to uneven stress of the assembly tool 2; the center line of the first reference plate 211 and the center line of the second reference plate 212 are in the same plane.

[0080] It should be noted that the first reference plate 211 and the second reference plate 212 are usually square plates, so as to be convenient for processing or obtaining and have larger contact area and better balance; and since the first positioning block 221 is fixedly arranged on one side surface of the second reference plate 212, by arranging the center line of the first reference plate 211 and the center line of the second reference plate 212 in the same plane, the gravity center of the reference assembly 21 as a whole is projected on the center line of the first reference plate 211, so as to make the balance of the reference assembly 21 as a whole better.

[0081] Similarly, the center line of the first positioning block 221, the center line of the second positioning block 222 and the center line of the third positioning block 223 are in the same plane. In this embodiment, the center line of the first reference plate 211 and the center line of the first positioning block 221 are in the same plane, so as to make the balance of the assembly tool 2 as a whole better.

[0082] As shown in Figure 9 , the application further provides an assembly method of a deflector, which adopts the assembly tool 2 and includes the following steps:

[0083] S1, install the mounting surface of the box body 11 to the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203;

[0084] S2, preliminarily position the target plate 12 with the box body 11;

[0085] S3, establish a reference coordinate system by the laser tracker with reference to the first reference surface 2101 and the second reference surface 2102;

[0086] S4, establish the actual profile of the target surface of the target plate 12 in the reference coordinate system by the laser tracker;

[0087] S5, compare the actual profile of the target surface with the ideal profile of the target surface;

[0088] If the deviation between the actual profile and the ideal profile is less than or equal to the upper limit of the allowable error value, the target plate is fixedly connected with the box body;

[0089] If the deviation between the actual profile and the ideal profile is greater than the upper limit of the allowable error value, the position of the target plate is adjusted until the deviation between the actual profile and the ideal profile is less than or equal to the upper limit of the allowable error value;

[0090] S6, connect multiple cooling flow channels in the target plate to form a serial cooling channel;

[0091] S7, perform a leak detection test on the cooling channel of the deflector.

[0092] Based on the above technical solution, the box body 11 is installed to the assembly tool 2 through the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203, and then the target plate 12 is preliminarily positioned with the box body 11. The first reference surface 2101 and the second reference surface 2102 of the assembly tool 2 are used to establish a reference coordinate system and obtain the actual profile of the target surface of the target plate 12 by cooperating with the laser tracker. The deviation between the actual profile and the ideal profile is compared with the allowable error value, and the target plate 12 is further adjusted or fixedly connected to the box body 11 according to the comparison result. Finally, multiple cooling flow channels in the target plate 12 are connected to form a serial cooling channel, so as to obtain a finished deflector product with high assembly precision, effectively guaranteeing the normal work of the deflector. The leak detection test is performed to guarantee that the cooling channel can normally perform the cooling work.

[0093] Further, as shown in Figure 1 and Figure 2 to specifically realize the acquisition of the actual profile of the target surface of the target plate 12, the step S4 of establishing the actual profile of the target surface of the target plate 12 in the reference coordinate system by the laser tracker specifically includes:

[0094] Collecting coordinate values of multiple points on the target surface of the target plate 12 in the reference coordinate system by the laser tracker; fitting the actual profile of the target surface of the target plate 12 in the reference coordinate system through the multiple coordinate values.

[0095] Further, as shown in Figure 8 Since the two side shapes of the divertor 1 also need to meet certain accuracy requirements to avoid interference when multiple divertors 1 are circumferentially arrayed and installed to the fusion device, the two side shapes of the divertor 1 need to be detected for accuracy; the step S7 includes the following steps before the step S7:

[0096] S7-0, dismounting the assembled divertor 1 from the assembly tooling 2;

[0097] Installing three divertors 1 to the shape detection tooling 4; the shape detection tooling 4 is provided with an installation space for simulating continuous installation of multiple divertors 1 to the fusion device, and the installation space includes multiple installation sites arranged concentrically and sequentially along the annular direction;

[0098] The three divertors 1 are sequentially installed on three continuous installation sites, the gap value between two adjacent divertors 1 is detected, and the gap value between the two side shapes of any two divertors 1 is detected by interchanging the positions of any two divertors 1.

[0099] If the gap value is within the allowable gap value range, it is considered that the shape accuracy of the divertor participating in the detection is qualified; if the gap value is not within the allowable gap value range, it is considered that the shape accuracy of the divertor participating in the detection is unqualified.

[0100] It can be understood that the gap value between the two side shapes of any two divertors 1 is obtained by interchanging, so as to improve the detection efficiency of the two side shape accuracy of multiple divertors 1, and by interchanging installation, whether there is interference between two adjacent divertors 1 can be used to quickly screen out the divertor with large deviation in shape, thereby effectively improving the shape detection efficiency.

[0101] It should be noted that the gap value between the two sides of any two deflection filters is as follows: the three deflection filters are defined as No. 1 deflection filter, No. 2 deflection filter and No. 3 deflection filter from left to right in the first installation, and the No. 2 deflection filter and the No. 3 deflection filter are taken as an example, the right side profile of the No. 2 deflection filter is adjacent to the left side profile of the No. 3 deflection filter in the first installation, so the gap value between the right side profile of the No. 2 deflection filter and the left side profile of the No. 3 deflection filter can be measured; the positions of the No. 2 deflection filter and the No. 3 deflection filter are exchanged, so that the right side profile of the No. 3 deflection filter is adjacent to the left side profile of the No. 2 deflection filter, and the corresponding gap value is measured, thereby realizing the detection of the gap value between the two sides of the No. 2 deflection filter and the No. 3 deflection filter.

[0102] Preferably, in the embodiment, the allowable gap value d is defined as 0 < d < 0.6 mm to ensure the accuracy of the two side profiles of the deflection filter 1.

[0103] Preferably, in the step S1, the mounting surface of the box body 11 is correspondingly mounted to the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203, and specifically includes:

[0104] S1-1, placing the assembly tool 2 on the mounting platform;

[0105] The levelness and perpendicularity of the assembly tool 2 are checked through the first reference surface 2101 and the second reference surface 2102;

[0106] S1-2, after adjusting the assembly tool 2 to meet the requirements of levelness and perpendicularity, the assembly tool 2 is fixedly connected to the mounting platform;

[0107] S1-3, placing the box body 11 to the assembly tool 2;

[0108] S1-4, adjusting the box body 11 until the projection of the center line thereof in the vertical direction coincides with the projection of the center line of the reference assembly 21 in the vertical direction;

[0109] S1-5, fixedly connecting the mounting surface of the box body 11 with the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203.

[0110] It can be understood that the levelness and perpendicularity of the assembly tool 2 are checked in combination with the mounting platform, the first reference surface 2101 and the second reference surface 2102, which establishes a basis for the reference coordinate system with high accuracy. And by adjusting the box body 11 until the projection of the center line thereof in the vertical direction coincides with the projection of the center line of the reference assembly 21 in the vertical direction, the origin is determined to establish the reference coordinate system.

[0111] Further, as Figure 1 ,Figure 2 and Figure 4 As shown, since the target plate 12 includes an inner target plate, a dome plate, and an outer target plate, in order to standardize the assembly process, step S2 involves initially positioning the target plate 12 and the box body 11, specifically including:
