Description

Technical Field

[0001] The present invention relates to the technical field of fusion superconducting coils, and particularly relates to a connection structure, a processing device and a processing method for superconductors. Background Art

[0002] In the manufacturing and forming process of nuclear fusion superconducting coils, a terminal box needs to be installed at the joint of the superconducting coils for connecting the superconducting coils. At present, the superconducting coil armor and the terminal box are connected by welding. When welding, it is necessary to ensure the levelness of the terminal box and minimize the rotational force that occurs when connecting the superconducting coils through the terminal box later, so as to prevent damage to the superconducting coils. Since the cost of a single sub-coil in the superconducting coil is as high as tens of millions, it will cause huge cost losses.

[0003] The existing welding method between the terminal box and the conductor armor is that after the position of the superconducting coil is fixed, the height and levelness of the terminal box are adjusted through a platform. After aligning and assembling the terminal box with the coil inside the armor, welding is carried out manually. The assembly accuracy between the armor and the terminal box directly affects quality problems such as the connection accuracy of the terminal box after welding. And because the positions where the armor and the terminal box need to be welded are relatively concentrated, the high welding temperature is likely to damage the superconducting cable inside, resulting in damage to the superconducting coil.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Referring to Figures 1 - 3 , an embodiment provided by the present invention: a connection structure of a superconductor, the connection structure is arranged on the sheathing 1, the connection structure includes a notch 4, a connecting ring 2 is arranged on the outer side of the sheathing 1, and the sheathing 1 and the connecting ring 2 are connected to the terminal box 3 through the connection structure, and a cavity is formed among the sheathing 1, the connecting ring 2 and the notch 4.

[0023] In this embodiment, the terminal box 3 and the sheathing 1 of the superconductor are connected by a welding connection method. The sheathing 1 is a rectangular structure and the material is 316LN stainless steel. However, the existing wall thickness of the sheathing 1 is insufficient. Therefore, in this embodiment, a connecting ring 2 is sleeved on the outer side of the sheathing 1 and welded to the terminal box 3 together to strengthen the weld. The connecting ring 2 is a rectangular ring adapted to the sheathing 1; a connection structure is processed at the end face on one side of the sheathing 1 of the superconductor, a connecting ring 2 is sleeved on the outer side of the sheathing 1, and the connecting ring 2, the connection structure and the terminal box 3 are assembled in alignment, and a cavity is formed at the connection structure, so that the root of the weld is not connected to the sheathing 1 during welding, and heat is avoided from directly conducting to the superconducting cable 101 inside through the superconductor during the welding process, resulting in damage to the superconducting cable 101.

[0024] The connection structure includes a notch 4, and at least one or more notches 4 are opened at the end face of the sheathing 1 close to the terminal box 3, and a first bevel 5 is opened on the outer side of the notch 4.

[0025] In this embodiment, the armor 1 has a rectangular structure. For the convenience of welding, the notch 4 is a rectangular groove. Specifically, there are four notches 4, the width of the rectangular groove is 2 mm, the depth is 4.5 mm, the outer side is 1-2 mm away from the surface of the armor, preferably 1.5 mm, and a first bevel 5 is provided on the outer side of the notch 4. The first bevel 5 is welded to the terminal box 3 to increase the welding area and strengthen the welding connection strength.

[0026] A superconducting cable 101 is arranged inside the armor 1, and the notch 4 is arranged around the outer side of the superconducting cable 101, so that a first protrusion 102 close to the superconducting cable 101 and a second protrusion 103 far from the superconducting cable 101 are formed at the end face of the armor 1; the notch 4 is parallel to the side face of the armor 1, so that the first protrusion 102 and the second protrusion 103 are parallel.

[0027] In this embodiment, a circular pipeline is opened inside the armor 1, a superconducting cable 101 is arranged inside, and the notch 4 is arranged around the outer side of the superconducting cable 101. When welding the armor 1, each side face of the armor 1 is provided with a notch 4 parallel to it. The notch 4 processes the end face of the armor 1 to form a first protrusion 102 and a second protrusion 103, and a cavity is formed in the middle. The first protrusion 102 and the second protrusion 103 are parallel, so that the thickness of the armor at the notch 4 is uniform, and the heat is evenly distributed at the side face of the armor 1 during welding.

[0028] A first bevel 5 is opened at the end face of the second protrusion 103 on the side close to the terminal box 3, and the slope direction of the first bevel 5 is inclined along the side close to the first protrusion 102 towards the connection ring 2.

[0029] In this embodiment, a first bevel 5 is opened at the end face of the second protrusion 103, and the angle of the first bevel 5 is 25-30°, preferably 27.5°. During assembly, it is convenient to match with the connection ring 2. The connection ring 2 is sleeved outside the armor 1. The slope direction of the first bevel 5 is inclined along the side close to the first protrusion 102 towards the connection ring 2, increasing the welding area with the terminal box 3.

[0030] The connection ring 2 is sleeved outside the second protrusion 103. A second bevel 201 with the same slope direction as the first bevel 5 is provided on the side of the connection ring 2 close to the terminal box 3. The first bevel 5 and the second bevel 201 are arranged in a staggered manner.

[0031] In this embodiment, the connecting ring 2 is a rectangular ring, which is adapted according to different armors 1 and terminal boxes 3. The outer end face is flush with the terminal box 3, the inner end face is adapted to the armor 1, and the gaps between the connecting ring 2 and the four sides of the armor 1 are less than 0.2 mm, and the gaps at the four corners are less than 0.5 mm. During assembly, a second bevel 201 is provided on the side of the connecting ring 2 close to the terminal box 3, and the first bevel 5 is located inside the connecting ring 2 to achieve a staggered arrangement. The angle of the second bevel 201 is 25 - 30°, preferably 27.5°.

[0032] On the outer side of the armor 1 and in the direction away from the first bevel 5, welding is performed at the joint with the connecting ring 2 to fix the relative positions of the connecting ring 2 and the armor 1, preventing misalignment during welding with the terminal box 3, which may cause torque on the inner superconducting cable 101 during subsequent assembly of the terminal box 3 and damage the superconducting cable 101.

[0033] A third bevel 301 is provided on the side of the terminal box 3 close to the armor 1, and the slope direction of the third bevel 301 is symmetrical to the slope direction of the first bevel 5.

[0034] In this embodiment, the angle of the third bevel 301 is 25 - 30°, preferably 27.5°, and the slope direction of the third bevel 301 is symmetrical to the slope direction of the first bevel 5. A full penetration welding method can be used to weld the terminal box 3 to the armor 1 and the connecting ring 2.

[0035] Refer to Figures 4 - 8 , and there is also an embodiment of a processing device, including: A base 6; A slide rail 7 is provided on the base 6, and a rotating mechanism 8 is provided on the slide rail 7 to enable the rotating mechanism 8 to move horizontally along the setting direction of the slide rail 7; An adjustment mechanism 9 is provided on the rotating mechanism 8, a cutting tool 10 is installed on the adjustment mechanism 9, and a positioning mechanism 11 is provided on one side of the base 6 where the slide rail 7 is located to position the superconductor; The superconductor is threaded through the center of the rotating mechanism 8. The adjustment mechanism 9 drives the cutting tool 10 to reciprocate along the radial direction of the rotating mechanism 8 to process the connecting structure of the superconductor. The rotating mechanism 8 drives the adjustment mechanism 9 to rotate to adjust the processing position, so that the cutting tool 10 processes a notch 4 at the end face of the armor 1 and forms a first protrusion 102 and a second protrusion 103, and continues to process at the second protrusion 103 to form a first bevel 5 to obtain the connecting structure of the superconductor.

[0036] In this embodiment, the connecting structure at the end face of the superconductor sheathing 1 is processed by the processing device designed in this application. A slide rail 7 and a positioning mechanism 11 are provided on a base 6. A rotating mechanism 8 approaches or moves away from the positioning mechanism 11 along the setting direction of the slide rail 7. The positioning mechanism 11 clamps and fixes the sheathing outside the superconductor. When it reaches the rotating mechanism 8, the adjusting mechanism 9 is driven to rotate by the rotating mechanism 8 to process the connecting structure at the end face of the sheathing 1 and at different directions of the superconducting cable. The position of the tool is controlled by the adjusting mechanism 9 to adjust the size of the processed connecting structure. The rotation direction and rotation speed of the tool 10 are controlled by a motor to process the end face of the sheathing.

[0037] By using the processing device to process the connecting structure of the superconductor, it is possible to avoid the superconductor being stressed by rotation, prevent internal damage, and cause huge cost waste. It is possible to process the sheathing with the tool 10 through the rotating mechanism 8 without moving the conductor, which is convenient for subsequent welding. The positioning mechanism 11 clamps the four sides of the superconductor to prevent the internal superconducting cable 101 from being damaged by the rotation of the superconductor, which affects the performance of the superconductor.

[0038] The rotating mechanism 8 includes a mounting frame 801. The bottom of the mounting frame 801 is connected to the slide rail 7. A rotating disk 802 is provided on the mounting frame 801. A driving component 803 is provided on one side of the rotating disk 802. A number of mounting holes 804 are provided on the rotating disk 802, and at least one or more adjusting mechanisms 9 are installed through the mounting holes 804.

[0039] In this embodiment, the mounting frame 801 is arranged on the slide rail 7, and a vertically arranged rotating disk 802 is provided on the other side. A driving component 803 is provided above the rotating disk 802 and meshes with the rotating disk 802 through gears. The driving component 803 is a stepping motor or a hand-cranked rotating gear, which provides power for the rotating disk 802 to drive the adjusting mechanism 9 to rotate. The rotating disk 802 is a concentric disk, and a number of mounting holes are equidistantly arranged in a ring for installing the adjusting mechanism 9. Specifically, two adjusting mechanisms 9 are provided and are relatively arranged on the rotating disk 802. The connecting structures in two directions can be processed simultaneously each time. After processing, the rotating disk 802 is controlled to rotate by the driving component 803, so that the adjusting mechanism 9 rotates 90°, and the connecting structures in the other two directions are processed. The adjusting mechanism 9 can specifically be an electric telescopic rod, and a tool 10 driven by a motor is installed above it to adjust the position of the tool 10.

[0040] The positioning mechanism 11 includes an alignment component 1101 and a chuck component 1102. The chuck component 1102 penetrates the rotating mechanism 8, so that the end face of the superconductor extends to the tool 10 for processing the connecting structure.

[0041] In this embodiment, the positioning mechanism 11 includes an alignment component 1101 and a chuck component 1102. The alignment component 1101 includes a platform. A clamp block is connected to the platform through a lead screw. The superconductor is placed on the platform, and the armor of the superconductor is aligned by the clamp block, so that the armor is passed through the chuck component 1102. The chuck component 1102 is composed of four circumferentially distributed calipers, which abut against the four sides of the armor to clamp the armor and adjust the parallelism and stability of the armor.

[0042] The tool 10 is a T-shaped tool or a tapered tool, which are respectively used for machining the notch and the first bevel.

[0043] Refer to Figure 9 , and there is also an embodiment of a processing method. The processing method is applicable to the connection structure and processing device of any one of the above technical solutions, including: S1: Clamp the armor of the superconductor through the chuck component, and confirm the current processing station and the tool. S2: Control the adjustment mechanism and the rotation mechanism to drive the tool to move, so that the tool moves to the horizontal position of the processing station at the end face of the armor. S3: Control the rotation mechanism to move along the slide rail towards the processing station, so that the tool moves to the processing station for processing. S4: Control the rotation mechanism to move in the reverse direction of the processing station, control the rotation mechanism to rotate, and return to step S3 until all processing stations are completed and then enter the next step. S5: Replace the tool, and return to step S1 until the connection structure is processed.

[0044] In this embodiment, the connection structure is processed by first machining the notch and then machining the first bevel. After clamping the four sides of the armor through the chuck component, the processing station is determined. Use a scriber to draw 8 lines on the end face of the armor to show the inner and outer boundaries of the rectangular groove. Measure the distance from the outer boundary line to the side of the armor with a vernier caliper, and the result should be within the range of 1-2 mm. After confirming the processing station, install the tool for machining the notch. Control the adjustment mechanism to drive the tool to move towards the horizontal position direction of the end face of the armor, so that the tool is at the same horizontal position as the processing station, and the rotation mechanism is aligned with the processing angle of the processing station to ensure that the armor is at the exact center of the two processing tools.

[0045] Adjust the rotating mechanism through the slide rail to adjust the advancing direction of the tool. Start the motor to control the rotation of the tool and begin to synchronously machine two symmetrical rectangular grooves. The machining is divided into two stages. The first stage is rough machining, and the second stage is finish machining. In the rough machining stage, set the machining depth to 4 mm and control the feed per pass at 0.1 mm. The target machining depth for finish machining is 0.5 mm, and the machining depth per step is 0.1 mm / step. After the rough machining of the two symmetrical rectangular grooves is completed, rotate the turntable of the equipment by 90 degrees to machine the remaining two symmetrical rectangular grooves. After the rough machining is completed, perform finish machining. Repeat the above steps.

[0046] After machining the groove openings, replace the tool to machine the first bevel. The bevel machining is also divided into two stages. The first stage is rough machining, and the second stage is finish machining. In the rough machining stage, set the machining thickness per pass to 0.15 mm and the feed speed to 0.25 mm / s, with a target machining thickness of 2.0 mm. In the finish machining stage, set the machining thickness per pass to 0.1 mm and the feed speed to 0.15 mm / s, with a target machining thickness of 0.5 mm. Synchronously machine two symmetrical first bevels. After the rough machining of the two symmetrical first bevels is completed, rotate the turntable of the equipment by 90 degrees to machine the remaining two symmetrical first bevels. After the rough machining is completed, perform finish machining. Repeat the above steps.
