Description

Technical Field

[0001] The invention relates to hexagonal tube correction, in particular to a hexagonal tube correction method. Background Art

[0002] Fuel assemblies are the core of the entire nuclear power system, and the quality of the tubing directly impacts the safe service life of the fuel assemblies and the proper operation of the reactor core. In current designs of new nuclear power systems, the outer sleeves for fuel assemblies are typically constructed from seamless hexagonal tubes with a special cross-section. During assembly, the two end faces of the hexagonal tubes must be butt-welded to components of the same cross-section. Given the long-term safety and stability required for nuclear power, the stringent quality requirements for hexagonal tubes during manufacturing are equally crucial during assembly. Because the components being butt-welded to the hexagonal tubes are relatively fixed in shape and position, to prevent torsional stress between the two components after butt welding, the projections of the two end faces of the hexagonal tubes must overlap (torsion tolerance) before welding.

[0003] During the manufacturing process of hexagonal tubes, after heat treatment, the tube shape will produce a certain degree of deformation and twisting, which makes it impossible to ensure that each edge is parallel to the center line, and cannot meet the requirements of the product's two end face projection overlap (twist degree) before welding.

[0004] To correct the deformation of a hexagonal tube, it is necessary to perform corrections. Existing correction methods include using a twisting device, which involves clamping the two ends of the hexagonal tube with two three-jaw chucks. One chuck is fixed, while the other is rotated to a certain angle, twisting the entire hexagon to correct its torsional deformation. However, this method of overall twisting is uncontrollable, and the correction angle is difficult to determine, resulting in unsatisfactory correction results. Another method uses a hexagonal sleeve for manual correction, but this method is labor-intensive and the correction angle is uncontrollable. Summary of the Invention

[0005] In order to solve the problem of difficult control of the correction angle, the present invention provides a hexagonal tube correction method, the specific technical solution is as follows:

[0036] The present invention will now be further described with reference to the accompanying drawings.

[0037] like Figures 1 to 10 As shown, a hexagonal tube correction method is performed using a hexagonal tube high-precision correction device, comprising the following steps:

[0038] Step 1: One end of the hexagonal tube is rotated and the other end is movably inserted into the orthopedic hexagonal sleeve 13, the driving hollow shaft 15 and the fixed hexagonal sleeve 25;

[0039] Step 2: The angle sensor 14 detects the current deviation angle of the hexagonal tube and transmits it to the control device;

[0040] Step 3: The control device starts the clutch 12 and the orthopedic drive device. The orthopedic drive device drives the hollow shaft 15 and the clutch 12 to drive the orthopedic hexagonal sleeve 13 to rotate. The orthopedic hexagonal sleeve 13 drives the hexagonal tube to rotate in the opposite direction of the deviation angle for correction;

[0041] Step 4: After the angle sensor 14 detects that the hexagonal tube has eliminated the deviation angle, the control device stops the orthopedic drive device and releases the clutch 12;

[0042] Step 5: The control device drives the orthopedic hexagonal sleeve 13, the driving hollow shaft 15 and the fixed hexagonal sleeve 25 to move to the set position through the moving device;

[0043] Step 6: The control device controls the clutch 12 and the orthopedic drive device to perform orthopedic surgery;

[0044] Repeat steps 5 and 6 until the entire hexagonal tube is corrected;

[0045] Step 7: The control device drives the orthopedic hexagonal sleeve 13, the driving hollow shaft 15 and the fixed hexagonal sleeve 25 to reset through the moving device, and detects the angle deviation of the entire hexagonal tube through the angle sensor 14.

[0046] The length of the hexagonal tube and the position of the corrective hexagonal sleeve 13 are detected by the grating scale 9 .

[0047] The angle compensation value is set in the control system so that the correction angle is the sum of the current deviation angle and the angle compensation value.

[0048] like Figures 2 to 8 As shown, the hexagonal tube high-precision orthopedic device includes an orthopedic base 1, a moving device, a moving base 10, an orthopedic hexagonal sleeve 13, an angle sensor 14, a driving hollow shaft 15, an orthopedic driving device, a clutch 12, a fixed hexagonal sleeve 25 and a rotating hexagonal sleeve 23. The moving base 10 is slidably mounted on the orthopedic base 1 through a linear guide pair. The moving device is mounted on the orthopedic base 1 and is connected to the moving base 10 for driving the moving base 10 to move. The orthopedic hexagonal sleeve 13 is rotatably mounted on the moving base 10 through a bearing; the angle sensor 14 is fixed on the moving base 10 and is arranged opposite to the orthopedic hexagonal sleeve 13 for detecting the current angle of the orthopedic hexagonal sleeve 13; the driving hollow shaft 15 is rotatably mounted on the moving base 10 through a bearing and is arranged opposite to the orthopedic hexagonal sleeve 13 and is coaxially arranged; the orthopedic driving device is mounted on the moving base 10 and is connected to the driving hollow shaft 15; the clutch 12 is respectively connected to the orthopedic hexagonal sleeve 13 and the driving hollow shaft 15; the fixed hexagonal sleeve 25 It is slidably installed on the orthopedic base 1 through a linear guide pair and is connected to the movable base 10, and is used to be slidably inserted on the hexagonal tube so that the hexagonal tube does not rotate; the rotating hexagonal sleeve 23 is rotatably installed on one end of the orthopedic base 1, and is used to be inserted into the end of the hexagonal tube so that the hexagonal tube can rotate freely; the clutch 12 causes the orthopedic hexagonal sleeve 13 to follow the driving hollow shaft 15 to rotate to correct the deviation angle of the hexagonal tube during correction, and the clutch 12 separates the orthopedic hexagonal sleeve 13 from the driving hollow shaft 15 when the movable base 10 moves so that the orthopedic hexagonal sleeve 13 can rotate freely.

[0049] One end of the hexagonal tube is installed in the rotating hexagonal sleeve 23, and the other end of the hexagonal tube is movably inserted in the driving hollow shaft 15, the corrective hexagonal sleeve 13 and the fixed hexagonal sleeve 25. The angle sensor 14 detects the distortion of the hexagonal tube, that is, the current deviation angle of the hexagonal tube, and then the clutch 12 is started. The clutch 12 causes the driving hollow shaft 15 and the corrective hexagonal sleeve 13 to rotate synchronously. Then the corrective driving device drives the driving hollow shaft 15 and the corrective hexagonal sleeve 13 to rotate, and the corrective hexagonal sleeve 13 drives the hexagonal tube to rotate. The angle sensor 14 detects the angle of the hexagonal tube in real time. When the hexagonal tube rotates to an angle that eliminates the distortion, the corrective driving device stops and completes the correction of the hexagonal tube at this position. Then the clutch 12 is released, so that the driving hollow shaft 15 is separated from the corrective hexagonal sleeve 13, and the corrective hexagonal sleeve 13 can rotate freely. After the moving device drives the corrective hexagonal sleeve 13 to move a set distance in the direction of the rotating hexagonal sleeve 23, the next section of the hexagonal tube is corrected until the correction of the entire hexagonal tube is completed.

[0050] The orthopedic base 1 is rectangular; two linear guides 2 are symmetrically fixed to the orthopedic base 1, and linear bearings 3 are slidably mounted on the linear guides 2. The linear bearings 3 are connected to the moving base 10 and the fixed hexagonal sleeve 25. The moving device includes a screw 4, a translation nut 8, and a translation servo motor 7. Two bearing blocks 6 are provided and fixedly mounted at both ends of the orthopedic base 1 to secure the screw 4. The screw 4 is connected to the translation servo motor 7 via a coupling 5, and the translation servo motor 7 drives the screw 4 to rotate. The translation nut 8 is mounted on the screw 4 and connected to the moving base 10. A grating scale 9 is mounted on the orthopedic base 1, parallel to the linear guide 2 on one side, and the reading head of the grating scale 9 is connected to the moving base 10.

[0051] Angle sensor 14 is mounted on the orthopedic hexagonal sleeve 13. A platform is provided on the upper portion of the orthopedic hexagonal sleeve 13 for horizontally mounting the angle sensor 14.

[0052] In order to facilitate the installation of the rotating hexagonal sleeve 23, the device further includes a rotating seat 22, which is fixed to one end of the orthopedic base 1 and is rotatably connected to the rotating hexagonal sleeve 23 through a bearing.

[0053] In order to facilitate the replacement of the fixed hexagonal sleeve 25 and improve versatility, a follower seat 24 is also included. The follower seat 24 is slidably mounted on the orthopedic base 1 through a linear guide pair. The follower seat 24 is connected to the movable base 10 through a follower rod 28. The fixed hexagonal sleeve 25 is fixed to the follower seat 24. The fixed hexagonal sleeve 25 can be replaced with different specifications as needed.

[0054] The clutch 12 is an electromagnetic friction plate clutch 12 .

[0055] The orthopedic hexagonal sleeve 13 is installed in the axial hole on the driven side of the clutch 12. The orthopedic hexagonal sleeve 13 has an overall circular exterior and is divided into two internal sections: a circular outer section and a hexagonal inner section, with the circular section slightly larger than the hexagonal section. The orthopedic drive device includes a drive box 11, a turbine 16, a worm 17, and an orthopedic servo motor 18. The drive box 11 is connected to the movable base 10 via a follower rod 28, and the drive box 11 can also be directly fixed to the movable base 10. The drive hollow shaft 15 is installed in the axial hole on the active side of the clutch 12. The interior is circular and larger than the outer dimensions of the hexagonal tube. The turbine 16 is mounted on the drive hollow shaft 15 and is rotatably mounted in the drive box 11 via a bearing. The turbine 16 also meshes with the worm 17. The worm 17 is connected to the orthopedic servo motor 18 via a coupling 19. The drive of the orthopedic servo motor 18 causes the worm rod 4 to rotate, thereby driving the turbine 16.

[0056] The turbine 16 is connected and fixed to the driving hollow shaft 15 by a flat key, and the orthopedic servo motor 18 drives the worm rod 17 to rotate, and the worm rod 17 drives the turbine 16 to rotate, thereby rotating the inner friction plate of the electromagnetic friction plate clutch 12; when the clutch 12 is not in action, the outer friction plate of the driven part of the clutch 12 is in a free state. When the coil 121 of the electromagnetic friction plate clutch 12 is energized, the armature 122 is attracted, so that the armature 122 slides to the right and presses the outer friction plate 123 and the inner friction plate 124, and the clutch 12 is engaged. The driving force is transmitted to the driven part of the clutch 12, driving the corrective hexagonal sleeve 13 to rotate; the coil 121 of the clutch 12 loses power, the armature 122 slides to the left to loosen the outer friction plate 123, the outer friction plate 123 is separated from the inner friction plate 124, the clutch 12 is opened, and the driven part of the clutch 12 is restored to a free state, thereby allowing the corrective hexagonal sleeve 13 to rotate freely. When the corrective hexagonal sleeve 13 moves on the hexagonal tube, it will not be stuck on the hexagonal tube due to the distortion of the hexagonal tube, which facilitates the movement of the corrective hexagonal sleeve 13.

[0057] In order to improve the stability during correction and make the force uniform, a locking device is also included. The locking device is provided on the movable seat 10 and the fixed hexagonal sleeve 25, and is arranged opposite to the orthopedic base 1 to fix the movable seat 10 and the fixed hexagonal sleeve 25 on the orthopedic base 1. The locking device includes a locking cylinder 20 and a locking block 21. The locking cylinder 20 is a hydraulic cylinder. The locking cylinder 20 is installed on both sides of the movable seat 10 and the fixed hexagonal sleeve 25. The locking block 21 is installed on the piston rod of the locking cylinder 20 and is movably inserted into the locking groove 31 of the orthopedic base 1. The locking groove 31 is provided along the length direction of the orthopedic base 1 and is a waist-shaped groove. The locking cylinder 20 presses the locking block 21 on the orthopedic base 1 to fix the movable seat 10. The locking block 21 is a T-shaped block.

[0058] The locking device further includes rollers 30, which are provided on both sides of the movable seat 10 and the fixed hexagonal sleeve 25 and movably abut against the orthopedic base 1. The rollers 30 can reduce the force on the linear guide pair and improve stability.

[0059] The follower rod 28 can adjust the distance between the movable seat 10 and the follower seat 24, making it easy to adjust according to the needs of the correction. Adjusting the distance between the movable seat 10 and the follower seat 24 is equivalent to adjusting the distance between the fixed hexagonal sleeve 25 and the correction hexagonal sleeve 13. A smaller distance can better constrain the corrected hexagonal tube and prevent it from deforming again.

[0060] Two modes, automatic and inching, are available. The translation servo motor 7 is controlled to move forward according to the translation distance. In the free state, the angle sensor 14 detects the deviation angle of the corresponding position of the hexagonal tube, which is transmitted to the correction servo motor 18. At the same time, a certain overcorrection angle is required according to the tube's rebound characteristics. A suitable value can be set in the angle compensation option. This angle compensation value is also controlled by the correction servo motor 18. Together, they control the reverse correction angle of the correction servo motor 18. After the correction is completed, the moving seat 10 retracts. During the retraction process, the grating ruler 9 and the angle sensor 14 are used to detect the overall length and angle deviation of the tube to ensure the quality of the correction and achieve high-precision correction.

[0061] During correction: the angle sensor 14 first detects the deviation angle of the current position of the hexagonal tube, transmits the data to the control device, and then the correction servo motor 18 rotates the corresponding correction angle. After the correction is completed, the moving device drives the moving seat 10 and the fixed hexagonal sleeve 25 to continue moving forward the set distance and perform correction until the overall correction of the hexagonal tube is completed.

[0062] One end of the hexagonal tube is movably inserted into a fixed hexagonal sleeve 25, which prevents the hexagonal tube from rotating. The fixed hexagonal sleeve 25 cooperates with the orthopedic hexagonal sleeve 13 to perform the correction. The hexagonal tube passes through the hollow drive shaft 15, and the other end of the hexagonal tube is inserted into the rotating hexagonal sleeve 23, which can rotate freely and follow the twist of the hexagonal tube. When clutch 12 is disengaged, the orthopedic hexagonal sleeve 13 can rotate freely, following the deflection of the hexagonal tube. Angle sensor 14, mounted horizontally, measures the deviation angle of the hexagonal tube's current position and transmits this data to the control device. Simultaneously, the angle compensation option in the HMI interface is filled in with the appropriate compensation angle based on the tube's performance. The two data are superimposed to determine the angle at which the orthopedic servo motor 18 needs to rotate in the opposite direction for the desired correction. Clutch 12 engages, and the orthopedic servo motor 18 begins operating. The worm gear 17 drives the worm gear 16, and the clutch 12's active portion rotates synchronously, causing the clutch 12's driven portion to rotate synchronously, rotating the orthopedic hexagonal sleeve 13 by the desired correction angle. Once the correction is complete, clutch 12 disengages, and the translation servo motor 7 begins operating according to the value set in the translation distance option in the HMI interface. Through the screw rod 4 and translation nut 8, it drives the moving base 10, drive box 11, and follower base 24 synchronously forward the set distance before stopping. A smaller translation distance setting increases the number of corrections required, achieving high-precision and precise corrections. The angle sensor 14 begins to transmit the deviation angle of the new position to the system, and the orthotic device begins a new round of orthotic action.

[0063] During the correction process, one end of the hexagonal tube is fixed to the rotating hexagonal sleeve 23 of the rotating seat 22. This end is free and can rotate at any angle. The other end of the hexagonal tube is movably inserted into the fixed hexagonal sleeve 25 of the follower seat 24. This end is fixed and cannot rotate. One side of the follower seat 24 is the completed correction part of the hexagonal tube. The fixed hexagonal sleeve 25 is used to assist in correction. During correction, it fixes the end of the hexagonal tube so that the hexagonal tube cannot rotate freely and brings the correction part close to the fixed part. This can ensure the quality of correction, reduce rebound after correction, and improve correction efficiency. The locking cylinders 20 at both ends of the drive box 11 and the follower seat 24 are firmly fixed to the correction base 1 through the locking blocks 21 when the correction servo motor 18 rotates, overcoming the large torque generated during correction and ensuring the stability of the mechanism.

[0064] Detection of overall length and angle deviation of the tube: After the overall correction of the hexagonal tube is completed, you can select the overall detection option in the HMI interface, click back, the translation servo motor 7 starts to rotate in the opposite direction, the moving seat 10 retracts, and the angle sensor 14 can detect the overall angle deviation of the hexagonal tube. The grating ruler 9 can measure the overall length of the tube and display it on the HMI interface.

[0065] like Figure 8 As shown in the figure, after stress relief, the hexagonal tube produces an angle of torsion, as shown in the figure. Figure 2 and Figure 3 As shown, the rotating hexagonal sleeve 23 of the rotating seat 22 to be corrected is placed, and the other end passes through the corrective hexagonal sleeve 13, the driving hollow shaft 15 and the fixed hexagonal sleeve 25. Figure 9 As shown, clutch 12 is disengaged, and the corrective hexagonal sleeve 13 is free to deflect along the shape of the hexagonal tube 29 and transmit the detected deviation angle to the control device. At this point, clutch 12's coil 121 is energized, engaging armature 122, causing it to slide rightward and compress outer friction plate 123 and inner friction plate 124. Clutch 12 is engaged, transmitting driving force to the driven portion of clutch 12. Locking cylinder 20 activates, firmly securing drive box 11 and follower seat 24 to corrective base 1. Corrective servo motor 18 begins to rotate in the opposite direction according to the deviation angle detected by angle sensor 14 and the compensation angle set in the HMI interface. This rotation, driven by worm gear 17 and turbine 16, drives corrective hexagonal sleeve 13 to correct the shape of hexagonal tube 29. During correction, the uncorrected portion of hexagonal tube 29 rotates within corrective hexagonal sleeve 13, while the corrected portion is restrained by fixed hexagonal sleeve 25, preventing torsional movement. After the correction is completed, the coil 121 of the clutch 12 loses power, the armature 122 slides to the left, the outer friction plate 123 and the inner friction plate 124 are separated, the clutch 12 is opened, and the driven part of the clutch 12 is restored to a free state, and the locking cylinder 20 is released at the same time; the translation servo motor 7 starts to move according to the set value of the translation distance in the HMI interface, and drives the moving seat 10, the drive box 11 and the follower seat 24 to move forward synchronously for the set distance through the screw rod 4 and the translation nut 8 and then stop; during the movement, the correction hexagonal sleeve 13 is in a free state, and after translation, the angle sensor 14 measures the deviation angle of the new position and transmits the data to the control device, and the correction servo motor 18 performs corresponding angle correction according to the new data. By repeating the above actions, the overall correction of the hexagonal tube is completed.

[0066] After the correction is completed, select the overall detection option in the HMI interface and click Back. The translation servo motor 7 starts to rotate in the opposite direction, and the moving seat 10 starts to retreat, driving the reading head of the grating ruler 9 to move. The overall length of the tube can be measured by the grating ruler 9. The correction hexagonal sleeve 13 is in a free state. During the translation process, the angle sensor 14 can detect the overall angular deviation of the hexagonal tube and display it on the HMI interface.
