Description

Technical Field

[0001] The present invention relates to a method and tooling for bonding and forming a flange of a composite material launcher tube, belonging to the technical field of processing composite material cylindrical bodies. Background Art

[0002] Large composite material launcher tubes are all cylindrical hollow thin-walled parts with a length close to 8 meters. During transportation and application, they need to be fixedly assembled, so it is necessary to sleeved multiple flanges for connection and fixation on their outer periphery (at least on the outer periphery at both ends). These flanges cannot be integrally formed with the cylinder body during the production of the cylinder body, and need to be adhesively fixed to the corresponding positions on the outer periphery of the launcher tube with adhesive after the production of the launcher tube is completed. The thickness of the adhesive reaches 1-3 mm, that is, there is a distance of 1-3 mm between the inner wall of the flange and the outer peripheral surface of the launcher tube, and it is strictly required that this distance is basically equal everywhere along the outer peripheral surface of the launcher tube, and the error shall not exceed 0.05 mm. This requires extremely high coaxiality when the flange is sleeved on the outer peripheral surface of the launcher tube.

[0003] In the existing process bonding, the commonly used method includes leveling with a level. Its defect is that there is no hardware-fixed standard, and visual adjustment is required each time, making it difficult to achieve quick and efficient alignment.

[0004] To solve the above problems, the patent document with the application number 202410817600.0 discloses a tooling for coaxial positioning and bonding of a cylinder flange and a method for installing a cylinder flange. Its basic technical measure is to perform coaxial positioning on the flange and the cylinder body. To ensure dense bonding, glue injection is carried out by means of sealing and vacuum extraction between the flange and the cylinder body, which requires sealing both sides of the gap between the flange and the cylinder body, and its process is too complex.

[0005] In addition, there is also a problem that is relatively laborious to solve in the above-mentioned prior art, that is, the flange is an interface mating part, and there are phase requirements for the connection structure in its circumferential direction. Not only is it easy to misalign before and after the structural adhesive cures during the bonding process, but it is also difficult to accurately position it when sleeving the flange, and it is necessary to repeatedly rotate the flange to align the phase with the cylinder body. Summary of the Invention

[0006] The main technical problem to be solved by the present invention is: how to quickly and standardly perform coaxial positioning on the flange and the launcher cylinder body through hardware facilities and carry out simple and dense glue injection bonding, and be able to easily adjust the phase of the flange connection structure.

[0007] In view of the above problems, the technical solution proposed by the present invention is: A method for bonding and forming a flange of a composite material launcher tube, comprising the following steps: S1. Set glue injection holes that communicate inside and outside on the flange; S2. Sleeve all the flanges to be bonded outside the launcher tube; S3. Implement rotatable support for the launcher tube; S4. By setting a flange clamping device, position the flange sleeved outside the launcher tube coaxially with the launcher tube, so that the distance of the gap between the inner wall of the flange and the outer peripheral surface of the launcher tube is equal everywhere; S5. Inject melted liquid glue into the gap through the glue injection hole. When the injected glue starts to overflow to both sides of the gap, rotate the launcher tube one week relative to the flange while injecting glue, and ensure that the injected liquid glue always overflows to both sides of the gap during the rotation process; S6. Rotate the flange and the launcher tube relatively to adjust the phase of the flange connection structure; S7. Cool. When the liquid glue loses its gravitational fluidity, fill the defects caused by the flow of the liquid glue on both sides of the gap and scrape off the excess glue overflowing on both sides of the gap; S8. Demold after curing.

[0008] Furthermore: There is one glue injection hole set in step S1, which is set at the axial center position on the left side of the flange, or at the axial center position on the right side of the flange.

[0009] Furthermore: There are multiple glue injection holes set in step S1. The multiple glue injection holes are arranged in an inverted V shape with the tip upward on the left side or the right side of the flange. The main glue injection hole is located at the tip, and the side glue injection holes are located on both sides. The main glue injection hole is located at the axial center of the flange. The number of glue injection holes on both sides is equal and the positions are symmetrical; Set from the main glue injection hole to the side glue injection holes outside both sides, and the aperture gradually becomes smaller.

[0010] Furthermore: Step S3 is to set a driving shaft and a driven shaft on the same axis. A driving mechanism capable of driving the driving shaft to rotate around the axis is set on the driving shaft. The driving shaft and the driven shaft are respectively inserted into the holes at both ends of the launcher tube to support the inner walls of the holes at both ends of the launcher tube.

[0011] Furthermore: Set a flange clamping device with four rotatable clamping wheels. When performing step S4, the four clamping wheels clamp and center the flange. When bonding multiple flanges simultaneously and performing S6, use the rotatable clamping wheels to manually apply a torsional force to the flange to rotate the flange, so as to achieve the phase calibration of the flange; When bonding multiple flanges in sequence and performing S6 on the flange being bonded, wait for the previously bonded flange to cure, rotate the launcher tube, and use the rotatable clamping wheels to make the previously bonded flange rotate with the launcher tube, so as to achieve the phase calibration of the flange being bonded.

Detailed implementation manners

[0020] The present invention will be further described below in conjunction with embodiments and the accompanying drawings: Embodiment 1

[0021] A method for bonding and forming a flange of a composite material launch tube (see Figure 1 , 4 ) includes the following steps: S1. Provide a glue injection hole 61 that is internally and externally connected on the flange 6; S2. Sleeve all the flanges 6 to be bonded outside the launch tube 7 near the position to be bonded; S3. Provide rotatable support for the launch tube 7; S4. Through the flange clamping device 3, position the flange 6 sleeved outside the launch tube 7 coaxially with the launch tube 7, so that the distance of the gap 607 between the inner wall of the flange 6 and the outer peripheral surface of the launch tube 7 is equal everywhere; S5. Inject molten liquid glue into the gap 607 through the glue injection hole 61. When the injected glue starts to overflow to both sides of the gap 607, rotate the launch tube 7 one week relative to the flange while injecting glue, and ensure that the injected liquid glue always overflows to both sides of the gap 607 during the rotation process; S6. Rotate the flange 6 and the launch tube 7 relative to each other to adjust the phase of the connection structure of the flange 6; S7. Cool. When the liquid glue loses its gravitational fluidity, fill the defects caused by the flow of the liquid glue on both sides of the gap 607 and scrape off the excess glue overflowing on both sides of the gap 607; S8. Demold after curing.

[0022] Here, the "overflow" refers to the state where the liquid glue fills both sides of the gap 607 in the glue injection area and starts to overflow outward.

[0023] In this way, by setting the flange clamping device 3, the flange 6 sleeved outside the launch tube 7 is positioned coaxially with the launch tube 7. Through the glue injection hole 61, high-temperature sol is injected into the gap 607 between the inner wall of the flange 6 and the outer peripheral surface of the launch tube 7, and a full overflow state is formed on both sides of the gap 607 in the glue injection area. By slowly rotating the launch tube 7, the gap is filled. Compared with the prior art that uses a level to calibrate the position and vacuum injection of glue, it can achieve more accurate and faster positioning, and the glue filling and phase adjustment are more convenient.

[0024] There is one glue injection hole 61 set in the above step S1, which is located at the axial center position on the left side of the flange 6, or at the axial center position on the right side of the flange 6. When injecting glue, the glue can flow equally to both sides.

[0025] As Figure 1 、 2 shown, the rotatable support for the launch tube 7 in step S3 is the driving shaft 11 and the driven shaft 21 arranged on the same axis. A driving mechanism capable of driving the driving shaft 11 to rotate around the axis is arranged on the driving shaft 11. The driving shaft 11 and the driven shaft 21 are respectively inserted into the holes at both ends of the launch tube 7 to support the inner walls of the holes at both ends of the launch tube 7. In this way, the interference of external support on the bonding of flanges at both ends of the launch tube 7 is avoided.

[0026] For the flange clamping device 3 provided with four rotatable clamping wheels 37, when performing step S4, the four clamping wheels 37 clamp and center the flange 6. When simultaneously bonding multiple flanges 6 and performing S6, the rotatable clamping wheels 37 are used to manually apply a torsional force to the flange 6 to rotate the flange, so as to achieve the phase calibration of the flange 6. In this way, when the launch tube is fixed, the flange 6 can be rotated when no glue is injected between the flange 6 and the launch tube 7 or when the glue has been injected but the glue has not solidified, and the phase adjustment can be easily performed. When sequentially bonding multiple flanges 6 and performing S6 on the flange 6 being bonded, after the previously bonded flange 6 is cured, the launch tube 7 is rotated, and the previously bonded flange 6 can be rotated along with the launch tube 7 by using the rotatable clamping wheels 37, and the flange 6 being bonded (the liquid glue has not solidified) is made stationary to achieve the phase calibration of the flange 6. Embodiment Two

[0027] As Figure 5As shown in the figure, the difference from the first embodiment is as follows: There are multiple glue injection holes 61 provided in step S1. The multiple glue injection holes 61 are arranged in an inverted V shape with the tip upward on the left or right side of the flange 6. The main glue injection hole 611 is located at the tip, and the side glue injection holes 612 are located on both sides. The main glue injection hole 611 is located at the axial center of the flange 6, and the number of side glue injection holes 612 on both sides is equal and the positions are symmetrical; it is set that from the main glue injection hole 611 to the side glue injection holes 612 outside both sides, the hole diameters gradually become smaller. When the launch tube 7 rotates, it rotates in the direction pointed by the tip of the inverted V shape. In this way, since the main glue injection hole 611 at the tip is the largest and the glue injection amount is the largest, it is located at the axial center of the flange 6 and travels in front when rotating with the launch tube 7, which can ensure that the axial middle area of the flange 6 is fully filled with glue and there will be no cavities. At the same time, since side glue injection holes 612 are provided on both sides, the glue injection speed can be ensured to be increased. Also, since the side glue injection holes 612 on the sides gradually decrease, the glue injection amount also relatively decreases successively. When it is seen that the liquid glue overflows on both sides of the gap 607, it proves that the middle area of the gap 607 has also been fully filled. Embodiment III

[0028] As Figure 1 —7 shows a composite material launch tube flange bonding and forming tooling, including: a general frame 100, a driven shaft support device 2 and a driving shaft support device 1 with a common axis line respectively arranged at the front end and the rear end of the general frame 100, a flange clamping device 3 for clamping the flange 6 and a pre-support device 4 for pre-supporting the launch tube 7 arranged on the general frame 100 between the driven shaft support device 2 and the driving shaft support device 1; a guide rail 101 is provided at the rear end of the general frame 100, and the driving shaft support device 1 can slide back and forth on the guide rail 101; the driving shaft support device 1 includes a driving shaft 11 and a driving mechanism for driving the driving shaft 11 to rotate, and the driven shaft support device 2 includes a driven shaft 21; during application, first slide the driving shaft support device 1 backward along the guide rail 101 to the preparatory position, place the launch tube 7 on the pre-support device 4 by a lifting tool, then slide the driving shaft support device 1 forward, support the front end and the rear end of the launch tube 7 by the driven shaft 21 and the driving shaft 11 respectively, clamp the flange 6 by the flange clamping device 3, make the distance between the inner wall of the flange 6 sleeved outside the launch tube 7 and the outer periphery of the launch tube 7 equal everywhere, inject glue into the gap 607 between the flange 6 and the launch tube 7 by a glue injection machine through the glue injection holes 61 provided on the flange 6, and rotate the launch tube 7 by the driving mechanism driving the driving shaft 11, so as to realize the bonding and forming of the flange 6 on the launch tube 7.

[0029] Here, the driving mechanism can be a conventional motor driving mechanism or a conventional rotating crank 12 driving mechanism (a worm and worm gear mechanism and / or a bevel gear transmission mechanism, which belongs to a conventional driving mechanism in the mechanical field).

[0030] As Figure 1 、 2As shown, the driving shaft support device 1 has a propulsion crank 13 for moving it back and forth on the guide rail 101.

[0031] Both the front end of the driving shaft 11 and the rear end of the driven shaft 21 are provided with a plurality of inner wall support claws 102 that are equally arc-length arranged and can radially expand and contract. The plurality of inner wall support claws 102 at the rear end of the driven shaft 21 and the plurality of inner wall support claws 102 at the front end of the driving shaft 11 respectively support the inner wall of the rear end and the inner wall of the front end of the launch tube 7, avoiding interference of external support with the flanges pasted at both ends of the launch tube 7.

[0032] As Figure 3 shown, the flange clamping device 3 includes an upper table body 31, a lower seat body 32, a lifter 33 and four clamping wheels 37, as well as a left clamping frame 34 and a right clamping frame 35 that are symmetrically arranged left and right on the upper table body 31 and can move symmetrically left and right on the upper table body 31. The four clamping wheels 37 are respectively arranged at the upper and lower sides on the right side of the left clamping frame 34 and the upper and lower sides on the left side of the right clamping frame 35. The left clamping frame 34 and the right clamping frame 35 respectively have a left turbine and a right turbine (not shown in the figure). The left turbine and the right turbine are engaged with the same clamping worm 36. The clamping worm 36 is respectively provided with a left-handed thread and a right-handed thread that are engaged with the left turbine and the right turbine. The left-handed thread and the right-handed thread have opposite helix directions. The clamping worm 36 is provided with a clamping crank 361. By shaking the clamping crank 361, the left clamping frame 34 and the right clamping frame 35 can be clamped towards each other or separated away from each other, realizing the clamping or releasing of the flange 6. The upper table body 31 is installed on the lower seat body 32, and the lifter 33 is installed between the upper table body 31 and the lower seat body 32. It has a manual crank 331. By shaking the manual crank 331, the upper table body 31 can be raised or lowered, which is used to adjust the distance between the inner wall of the flange 6 and the outer circumference of the launch tube 7. It should be noted here that the left and right positions of the flange clamping device 3 are adjusted during installation. When the flange 6 and the launch tube 7 are coaxially positioned, no left and right direction adjustment is required.

[0033] As Figure 6 、 7As shown in the figure, the pre-support device 4 includes an upper body two 41, a lower seat body two 42, a lifter two 43 and a positioning wheel 44. The upper body two 41 is installed on the lower seat body two 42. The lifter two 43 is installed between the upper body two 41 and the lower seat body two 42 and has a manual crank two 431. The positioning wheel 44 is horizontally installed on the top of the upper body two 41. The left and right sides of the positioning wheel 44 are conical bodies, and the tips of the conical bodies on both sides of the positioning wheel 44 face each other, forming a V-shaped groove 441 around the middle of the positioning wheel 44. The positioning wheel 44 is fixed on the mounting shaft 45. Both ends of the mounting shaft 45 are horizontally slidably installed on the upper body two 41 through bearings 46. The ends of both ends of the mounting shaft 45 have fine-tuning stops 47 with threaded fit. The outside of the fine-tuning stops 47 at both ends of the mounting shaft 45 has blocks 48 fixed on the upper body two 41 and capable of pressing against the fine-tuning stops 47. The distance between the two fine-tuning stops 47 is greater than the length of the mounting shaft 45. In this way, regardless of the diameter of the launcher tube 7, it can fall into the V-shaped groove 441 to implement axial positioning. By turning the manual crank two 431, the upper body two 41 can be raised or lowered to adjust the height of the supported launcher tube 7. By rotating the two fine-tuning stops 47, the supported launcher tube 7 can be finely adjusted left and right, so that the inner wall support claws 102 at the front end of the driving shaft 11 and the rear end of the driven shaft 21 can smoothly enter the tube holes at both ends of the launcher tube 7. Embodiment 4

[0034] As Figure 8 shown in the figure, the difference from Embodiment 3 is that the flange bonding forming tooling further includes a middle section lifting device 5. The middle section lifting device 5 includes an upper body three 51, a lower seat body three 52, a lifter three 53 and a support wheel 54. The upper body three 51 is installed on the lower seat body three 52. The lifter three 53 is installed between the upper body three 51 and the lower seat body three 52 and has a manual crank three 531. There are two support wheels 54, symmetrically installed on both sides of the top of the upper body three 51, and used to support the lower sides of the middle section of the launcher tube 7 to rotate as the launcher tube 7 rotates when the launcher tube 7 is rotated. When bonding is carried out to rotate the launcher tube 7, turn the manual crank three 531 to make the two support wheels 54 support the two sides of the middle of the launcher tube 7 left and right, and then lower the upper body two 41 of the pre-support device 4. In this way, it can be ensured that the middle of the launcher tube 7 will not deform due to gravity sinking, and it can also be ensured that the launcher tube 7 can rotate normally.

[0035] The above embodiments are only used to describe the present invention more clearly and should not be regarded as limiting the protection scope covered by the present invention. Any equivalent form of modification should be regarded as falling within the protection scope covered by the present invention.
