DETAILED DESCRIPTION

[0068] In order to make the purpose, technical scheme and advantages of the application more clear, the application is further described in detail below by examples and in conjunction with the drawings. It should be understood that the specific examples described herein are only used to explain the application and do not limit the application.

[0069] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects and do not have any order or technical meaning. The "connection" and "coupling" of the application, unless otherwise specified, include direct and indirect connection (coupling). In the description of the application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the application and simplify the description, and therefore cannot be understood as limiting the application. The device or element must have a particular orientation, be constructed and operated in a particular orientation.

[0070] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "over", "above" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher than the second feature in horizontal height. The first feature "under", "below" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower than the second feature in horizontal height.

[0071] Referring to Figures 1-13 , the AP assembly has a total length of 15535.3 mm, a width of 2668.4 mm, and a height of 1165.3 mm (the thinnest plate thickness is 50.2 mm, and the thickest plate thickness is 98.3 mm), and weighs 13071 kg, with a single weight of about 6535.5 kg.

[0072] The present application discloses a cutting positioning tool for a large nuclear fusion coil AP assembly, which comprises an AP splicing assembly 1 including a single plate one 101 and a single plate two 102. Since the AP splicing assembly 1 is large, it is disassembled into the single plate one 101 and the single plate two 102 for cutting processing. Figure 1 As shown in the drawings, the single plate one 101 and the single plate two 102 are each divided into a straight section and a circular arc section. The circular arc section of the single plate one 101 and the single plate two 102 is prone to deformation, and the product size is easily affected by metal cutting and hoisting methods. In addition, the side edges of the plates are in the form of a circular arc, and the plates are relatively thin. In addition, there is a U-shaped groove on the inner side surface, which is located at the straight section and the circular arc section (as shown in the drawings). Figure 6 Finally, the cover plate bevel flat surface is processed (as shown in the drawings), and the clamping is performed after turning over. Figure 12 The AP plate processing is very difficult due to various factors, and the tool is needed to solve the turning over and hoisting and auxiliary processing.

[0073] The upper mounting tool 2 and the lower mounting tool 3 are respectively arranged at the top and the bottom of the single plate one 101 or the single plate two 102 for positioning and mounting the single plate one 101 or the single plate two 102. The upper mounting tool 2 and the lower mounting tool 3 each comprise an upper and lower connecting plate 201, an outer side plate 202 and an inner side plate 205. The upper and lower connecting plate 201 is located between the outer side plate 202 and the inner side plate 205 and is fixed by welding. A plurality of outer and inner connecting plates 203 are welded between the outer side plate 202, the upper and lower connecting plate 201 and the inner side plate 205.

[0074] The outer mounting tool 5 and the inner mounting tool 6 are arranged between the upper mounting tool 2 and the lower mounting tool 3, and the upper mounting tool 2, the lower mounting tool 3, the outer mounting tool 5 and the inner mounting tool 6 form a cladding chamber for positioning the single plate one 101 or the single plate two 102. The outer mounting tool 5 and the inner mounting tool 6 each include a plurality of equidistantly distributed upper fixing frames 501 and lower fixing frames 502. The upper fixing frames 501 and the lower fixing frames 502 are detachably mounted with the upper mounting tool 2 and the lower mounting tool 3 by screws. An equal-height pad 505 is arranged between the upper fixing frames 501 and the lower fixing frames 502 and is detachably mounted by screws. Adjacent two upper fixing frames 501 and adjacent two lower fixing frames 502 are detachably mounted with a middle connecting frame 503 by screws.

[0075] When the mounting tool is mounted, the upper and lower connecting plates 201, the outer side plate 202 and the inner side plate 205 and the plurality of outer and inner connecting plates 203 are assembled and spot-welded to form the upper mounting tool 2. The above-mentioned operation is repeated to assemble and spot-weld the lower mounting tool 3. Then, the lower mounting tool 3 is placed on the processing platform. At this time, one of the single plates to be processed is hoisted and placed on the lower mounting tool 3 in a side-standing manner. Then, the plurality of lower fixing frames 502 of the outer mounting tool 5 and the inner mounting tool 6 are sequentially mounted on the lower mounting tool 3, and adjacent two lower fixing frames 502 are connected and fixed by the middle connecting frame 503. Then, the plurality of upper fixing frames 501 of the outer mounting tool 5 and the inner mounting tool 6 are sequentially mounted on the top of the lower fixing frame 502, and the equal-height pad 505 is arranged between the upper fixing frame 501 and the lower fixing frame 502. Then, the assembled upper mounting tool 2 is placed on the top of the single plate and is supported by the plurality of upper fixing frames 501. At this time, the upper mounting tool 2 is connected and fixed with the upper fixing frame 501 by screws.

[0076] Since the single plate is located between the upper mounting tool 2 and the lower mounting tool 3, it is easy to cause irreversible collision and breakage of the corners of the single plate. Therefore, a plurality of nylon blocks 7 are arranged on the side of the upper mounting tool 2 and the lower mounting tool 3 close to the single plate one 101 or the single plate two 102, for supporting the single plate one 101 or the single plate two 102; thereby effectively protecting the single plate.

[0077] Since the single piece plate is heavy and is installed in the cladding chamber formed between the upper installation tool 2, the lower installation tool 3, the outer side installation tool 5 and the inner side installation tool 6, the position thereof is inconvenient to adjust, if deflection or the like occurs, greatly influences the subsequent machining cutting size, therefore a plurality of equidistantly distributed supporting bolts 504 are arranged on the outer side installation tool 5 and the inner side installation tool 6, the end portion of the supporting bolt 504 is rotatably connected with the end head of the same material as the AP assembly, at this time, the position of the single piece plate located in the cladding chamber can be adjusted by rotating the supporting bolt 504 to extrude the single piece plate, and the single piece plate in contact with the supporting bolt 504 is effectively protected by the end head of the same material as the AP assembly arranged on the end portion of the supporting bolt 504.

[0078] In order to further improve the strength and stability of the tool, the supporting I-beam frame 4 is arranged on one side of the upper installation tool 2 and the lower installation tool 3, which is used for supporting the tool to turn over, the supporting I-beam frame 4 comprises an upper I-beam 401 and a lower I-beam 404 which are detachably installed on one end of the upper installation tool 2 and the lower installation tool 3 through screws, a plurality of upper and lower connecting I-beams 402 are detachably installed between the upper I-beam 401 and the lower I-beam 404 through screws, and a plurality of side connecting I-beams 403 are detachably installed between the upper I-beam 401 and the lower I-beam 404 and the upper installation tool 2 and the lower installation tool 3 through screws.

[0079] At this time, the upper I-beam 401 and the lower I-beam 404 are assembled with the plurality of upper and lower connecting I-beams 402 and the side connecting I-beams 403, then the components are fixed through screws, and the supporting I-beam frame 4 is formed, then the supporting I-beam frame 4 is connected and fixed with the upper installation tool 2 and the lower installation tool 3 through screws, and the top and the bottom of the supporting I-beam frame 4 are flush with the top and the bottom of the upper installation tool 2 and the lower installation tool 3 respectively.

[0080] In the present application, one side of one of the upper I-beams 401 is provided with a flat lifting hole 406, and one side of each of the two outer and inner connecting plates 203 is provided with a flat lifting hole 406, one side of the outer plate 202 of the upper installation tool 2 and the lower installation tool 3 is welded with a turning lifting lug 405, and the two sides of the two outer and inner connecting plates 203 provided with the flat lifting hole 406 are welded with a plurality of reinforcing rib plates 204 which are connected and fixed with the upper and lower connecting plates 201. Since the gravity center of the workpiece is in the middle position, at this time, the four flat lifting holes 406 are arranged to facilitate the flat lifting operation of the tool, the plurality of reinforcing rib plates 204 are arranged to effectively avoid the deformation of the upper and lower connecting plates 201 during lifting, and when the workpiece needs to be turned over, the four turning lifting lugs 405 are arranged for lifting and turning operation.

[0081] During the cutting process of the single-piece plate, although the single-piece plate is located in the tooling, it is in an unfixed state. Therefore, the workpiece jitter generated during the cutting process of the single-piece plate has a greater impact on the cutting accuracy. Therefore, a pressure plate assembly 9 is provided, which can be detachably mounted on the outer mounting tooling 5 or the inner mounting tooling 6 by screws to fix the AP component during cutting. The pressure plate assembly 9 includes an adjustment plate 901. The adjustment plate 901 has a waist-shaped adjustment groove for screw insertion and fixing. The end of the adjustment plate 901 is fixed with a pressure block 902 of the same material as the AP component by bolts. When cutting, it is first necessary to determine the cutting part, and then remove the part of the tooling that blocks the cutting (such as Figure 8 As shown in the figure, the top and inner side of the single-piece board are cut, and the adjustment plate 901 can be fixed to the outer mounting fixture 5 by screws, and the exposed part of the single-piece board is pressed and fixed by the pressing block 902, thereby effectively preventing the workpiece jitter generated during the cutting process from having a significant impact on the cutting accuracy. The pressing block 902 is made of the same material as the AP component and can effectively protect the AP component.

[0082] After the two single-piece panels are cut, they need to be spliced ​​together. To splice the two single-piece panels, the two toolings need to be spliced ​​together first. Therefore, an assembled I-beam frame 8 and an I-beam connector 803 are set. The assembled I-beam frame 8 includes auxiliary I-beams 802 that are detachably mounted on the top, bottom and one side of the assembled supporting I-beam frame 4 by screws, wherein two front lifting ears 801 are welded to the top of the two auxiliary I-beams 802, and the I-beam connector 803 is detachably mounted at the joints of the two supporting I-beam frames 4 by screws. A plurality of mutually supporting horizontal connecting toolings 804 and vertical connecting toolings 805 are detachably mounted at the joints of the two upper mounting toolings 2 and the two lower mounting toolings 3 by screws.

[0083] During assembly, the two toolings need to be spliced ​​together, and then the two toolings are connected and fixed through the I-beam connector 803, the horizontal connecting tooling 804 and the vertical connecting tooling 805. After the connection and fixation are completed, the two spliced ​​single-piece plates need to be welded and subsequently cut. Therefore, in order to avoid deformation of the workpiece, a pair of auxiliary I-beams 802 are detachably installed on the top, bottom and one side of the spliced ​​tooling through screws. Therefore, not only can the spliced ​​tooling be supported by the auxiliary I-beams 802, but the joints of the two toolings are also reinforced for a second time, and the horizontality of the spliced ​​tooling is also ensured. Two front lifting ears 801 are welded on the top of two of the auxiliary I-beams 802. These four front lifting ears 801 are located at the center of gravity of the spliced ​​tooling, which facilitates subsequent lifting operations.

[0084] The present invention is divided into the following steps when used:

[0085] S1: Before cutting, the single-piece plate 101 and the single-piece plate 2 102 need to be installed in two sets of tooling respectively;

[0086] S2: First, install the single-piece plate 101, assemble and weld the upper and lower connecting plates 201, the outer plate 202, the inner plate 205, and the multiple outer and inner connecting plates 203 into the upper installation tool 2, and then repeat the above steps to assemble and weld the lower installation tool 3. Then, place multiple nylon blocks 7 at equal distances on the top of the lower installation tool 3. At this time, one of the single-piece plates 101 to be processed is hoisted and placed sideways on the multiple nylon blocks 7 placed on the lower installation tool 3;

[0087] S3: Then, multiple lower fixing frames 502 of the outer mounting tool 5 and the inner mounting tool 6 are sequentially mounted on the lower mounting tool 3, and two adjacent lower fixing frames 502 are connected and fixed by the middle connecting frame 503. Then, multiple upper fixing frames 501 of the outer mounting tool 5 and the inner mounting tool 6 are sequentially mounted on top of the lower fixing frame 502, and equal height pads 505 are inserted between the upper fixing frames 501 and the lower fixing frames 502. Then, the assembled upper mounting tool 2 is placed on top of the single-piece board 101 and supported by multiple upper fixing frames 501. At this time, the upper mounting tool 2 is connected and fixed to the upper fixing frame 501 by screws. At this point, the preliminary tooling installation of the single-piece board 101 is completed.

[0088] S4: The position of the single-piece plate 101 needs to be adjusted. In this case, the support bolt 504 is rotated so that the support bolt 504 presses the single-piece plate 101 in the coating chamber through the end thereof and fine-tunes the position of the single-piece plate 101.

[0089] S5: Then, the upper I-beam 401 and the lower I-beam 404 are assembled with the upper and lower connecting I-beams 402 and the side connecting I-beams 403, and then the components are fixed with screws to form a supporting I-beam frame 4. Then, the supporting I-beam frame 4 is connected and fixed with the upper installation tool 2 and the lower installation tool 3 by screws, and the top and bottom of the supporting I-beam frame 4 are flush with the top and bottom of the upper installation tool 2 and the lower installation tool 3 respectively. At this time, the entire installation of the single-piece plate 101 tool is completed;

[0090] S6: At this time, the tooling can be hoisted horizontally through the four horizontal hoisting holes 406, so that the tooling with the single-piece plate 101 installed can be hoisted to the processing table of the cutting station, and then the single-piece plate 101 can be cut. The cutting operation is divided into four steps;

[0091] S7: The first step of cutting operation is to determine the cutting part first, and then remove the tooling that blocks the cutting (such as Figure 8If the top and inner side of the single plate 101 are machined, the upper fixing frame 501 of the inner side installation tool 6 is dismounted (as shown in Figure 7 When the side end of the single plate 101 is machined, the upper fixing frame 501 of the inner side installation tool 6 is dismounted, so that the upper half of the inner side of the single plate 101 is exposed, and then the pressing plate assembly 9 is connected with the outer side installation tool 5, and the pressing block 902 of the pressing plate assembly 9 presses the top of the single plate 101, and then the upper half of the inner side of the single plate 101 is machined (as shown in Figure 6

[0092] S8: After the first step of machining is completed, the second step of machining is performed, at first, the upper fixing frame 501 of the dismounted inner side installation tool 6 is reinstalled, and then the upper fixing frame 501 of the outer side installation tool 5 is completely dismounted, at this time, the pressing plate assembly 9 is connected with the inner side installation tool 6, and the pressing block 902 of the pressing plate assembly 9 presses the top of the single plate 101 (as shown in Figure 9 At this time, the upper half of the outer side of the single plate 101 is exposed, and then the upper half of the outer side of the single plate 101 is machined (as shown in Figure 6

[0093] S9: After the second step of machining is completed, the third step of machining is performed, at first, the upper fixing frame 501 of the dismounted outer side installation tool 5 is reinstalled, and then the upper installation tool 2 is reinstalled, and then the helicopter crane turns over the cut single plate 101 and the tool through the turning ear 405, after the turning is completed, the S7 operation is repeated according to actual requirements, and the remaining half of the inner side of the single plate 101 is machined;

[0094] S10: After the third step of machining is completed, the fourth step of machining is performed, at this time, the S8 operation is repeated according to actual requirements, and the remaining half of the outer side of the single plate 101 is machined until the machining is completed;

[0095] S11: After the single plate 101 is machined, the above operation is repeated to machine the single plate 102, and when the single plate 102 is also machined, the splicing operation is performed;

[0096] S12: When the single plate 101 and the single plate 102 are spliced, the helicopter crane horizontally hoists the tool of the single plate 101 and the single plate 102 through the horizontal hoisting hole 406, and then the single plate 101, the single plate 102 and the tool are butt jointed;

[0097] ​​S13: When docking, the tooling is docked first, and then the two toolings are connected and fixed through the I-beam connecting piece 803 and the transverse connecting tooling 804 and the vertical connecting tooling 805. After the connection and fixation are completed, the two single plates after splicing need to be welded and subsequent cutting operations, so as to avoid workpiece deformation. At this time, a pair of auxiliary I-beams 802 is detachably installed on the top, bottom and one side of the spliced tooling through screws. At this time, the single plate one 101 and the single plate two 102 after splicing need to be welded. When welding, some blocking parts, such as the transverse connecting tooling 804 and the vertical connecting tooling 805, need to be partially removed.

[0098] S14: After welding, secondary cutting operation is needed. At this time, the crane lifts the spliced tooling and the single plate one 101 and the single plate two 102 to the cutting processing workbench through the four front lifting ears 801, then removes the upper installation tooling 2 of the tooling of the single plate one 101 and the single plate two 102 (as shown in Figure 13

[0099] S15: At this time, the U-shaped groove at the spliced welding position of the upper half of the single plate one 101 and the single plate two 102 is cut and connected, and then the side end of the single plate one 101 and the single plate two 102 is beveling (as shown in Figure 12

[0100] S16: After turning over, the lower installation tooling 3 of the tooling of the single plate one 101 and the single plate two 102 is removed, and then the cutting operation of S15 is repeated until the cutting operation of the single plate one 101 and the single plate two 102 is completed, that is, the cutting operation of the AP splicing assembly 1 is completed.

[0101] S17: During the cutting process, the machine tool detects the workpiece deformation at any time, and contacts the nuclear laser simulation comparison. If there is no error, the machining can continue.
