Description

Technical Field

[0001] The present invention relates to the technical field of composite material assembly processes, and specifically relates to a tooling and an assembly forming method. Background Art

[0002] In the fields of machining and manufacturing, the assembly forming of different materials is often involved, especially the assembly process forming of composite materials in aircraft production. For example, a cabin section of an aircraft is formed by sleeving and bonding and curing a cylindrical structural member with a rotating body structure and a metal shell or a carbon fiber shell. The cylindrical structural member is sleeved outside the shell. Generally, the size of the cylindrical structural member is 150 mm to 700 mm, and the thickness is 10 mm to 15 mm. The cylindrical structural member is often designed as a composite material member with good rigidity and blind holes or a low-density composite material with low rigidity and a through hole in the center hole. However, due to the material characteristics, structural characteristics of the cylindrical structural member itself and the characteristics of the auxiliary bonding material, for the cylindrical structural member of low-density composite material, debonding is likely to occur at the blind hole, and deformation is likely to occur on the outer periphery; for the cylindrical structural member of composite material, the sleeving with the shell is likely to not reach the specified position.

[0003] In summary, when the cylindrical structural member of composite material is assembled and formed with the shell, there are technical problems such as being difficult to place in place, difficult to position, easy to deform, and easy to debond, and it is difficult to meet the design requirements. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a tooling and an assembly forming method dedicated to the assembly process. The tooling is provided with comprehensive positioning measures, which can avoid dimensional tolerance caused by poor positioning. The whole process is controllable in technology, the quality of the prepared product is good in stability, and the preparation efficiency is high.

[0005] The solution to achieve the technical purpose of the present invention is a tooling, which is characterized in that it is used for the assembly forming of a cabin section. The cabin section includes a shell and a cylindrical structural member sleeved outside the shell. The tooling includes:

[0006] A clamping ring assembly, including a clamping ring body, and the clamping ring body is provided with an inner cavity matching the outer diameter size of the cylindrical structural member;

[0007] A frame, provided with an operation platform, an upper top plate, a driving component for driving the upper top plate to lift, and a locking mechanism for fixing the clamping ring assembly to the operation platform. The upper top plate is located above the operation platform;

[0009] Two or more positioning structures, the positioning structure including a matching protrusion and a receiving portion, one of the protrusion and the receiving portion being provided on the loop body and the other being provided on the upper cover plate; the two or more positioning structures are circumferentially spaced along the loop body and the upper cover plate, and the axis of the positioning structure is parallel to the axis of the loop body.

[0010] In some embodiments, the diameter of the inner cavity of the loop body is 0.1 mm to 1 mm larger than the outer diameter of the cylindrical structural member.

[0011] In some embodiments, the loop assembly further includes a support frame, the loop body being detachably connected to the top surface of the support frame; the support frame is provided with support feet, and the locking mechanism is used to position the support feet on the work platform.

[0012] In some embodiments, the tooling further includes a flow guiding member, the flow guiding member including a connected cylindrical section and a conical section, the large diameter end of the conical section being connected to the cylindrical section, the outer diameter of the cylindrical section being equal to the maximum outer diameter of the conical section, and the end face of the cylindrical section being used to fit the lower end face of the housing.

[0013] In some embodiments, the inclination angle of the generatrix of the conical section is 0.5° to 5°; the outer diameter of the flow guiding member is 0.1 mm to 4 mm smaller than the outer diameter of the housing.

[0014] In some embodiments, the tooling further includes an adapter plate detachably connected to the upper end face of the loop body, so that the top surface of the adapter plate is flush with the upper end face of the cylindrical structural member, the adapter plate is used to contact the upper cover plate, and the upper cover plate is further provided with a counterbore matching the end size of the housing.

[0015] In some embodiments, the number of the adapter plates is at least two, and the at least two adapter plates are circumferentially spaced along the loop body;

[0016] The tooling further includes at least one pressing block, the pressing block being detachably provided on the upper end face of the loop body for positioning the cylindrical structural member.

[0017] In some embodiments, the frame is provided with an installation platform, the tooling further includes a lower base plate, and the lower base plate and the installation platform are movably connected by a positioning pin; the lower base plate constitutes the work platform, and the locking mechanism is provided on the lower base plate.

[0018] In some embodiments, the installation platform is provided with a slide rail, and the lower base plate is slidably engaged with the slide rail.

[0019] Based on the same inventive concept, the present invention also provides a set forming method implemented based on the above-mentioned tooling. The set forming method includes the following steps:

[0020] Position the upper cover plate and the housing with positioning pins and fix them by screwing; connect and fix the upper cover plate and the upper top plate; place the clamping ring body on the operation platform, and place the structural member into the inner cavity of the clamping ring body;

[0021] Conduct a trial set positioning. Drive the upper top plate to descend through the driving assembly, and adjust the position of the clamping ring body so that the protruding part and the receiving part on the clamping ring body and the upper cover plate are butted and slidably matched, thereby determining the docking position of the clamping ring body on the operation platform, and lock and position the clamping ring body through the locking mechanism;

[0022] Drive the upper top plate to ascend through the driving assembly to separate the housing and the cylindrical structural member, and apply glue to the inner bonding surface of the cylindrical structural member;

[0023] Drive the upper top plate to descend through the driving assembly, conduct the set of the housing and the cylindrical structural member, and perform a curing treatment to obtain the cabin section.

[0024] As can be seen from the above technical solutions, a tooling provided by the present invention includes a clamping ring assembly, a frame, an upper cover plate and more than 2 groups of positioning structures, wherein: the clamping ring assembly includes a clamping ring body, and the clamping ring body is provided with an inner cavity matching the outer diameter size of the cylindrical structural member, so as to position and shape the outer contour surface of the cylindrical structural member during the set process, effectively realizing the shape control of the cylindrical structural member during the set process, preventing its size change, and playing a role in controlling its relative position. The frame is provided with an operation platform, an upper top plate, a driving assembly for driving the upper top plate to lift and lower, and a locking mechanism for fixing the clamping ring assembly to the operation platform. The upper top plate is located above the operation platform. The upper cover plate is used to connect the upper end surface of the housing and the upper top plate. The upper top plate and the housing are connected to two opposite sides of the upper cover plate, that is, the housing and the upper top plate are connected as a whole through the upper cover plate. Taking the clamping ring assembly arranged on the operation platform as a reference, the housing is placed into the central hole of the cylindrical structural member from top to bottom under the action of the driving assembly. The positioning structure includes a matching protruding part and a receiving part. Among the protruding part and the receiving part, one is arranged on the clamping ring body and the other is arranged on the upper cover plate, so that when the housing, the upper cover plate and the upper top plate descend together until the upper cover plate is close to the upper end surface of the clamping ring body, the receiving part and the protruding part are butted and matched, thereby determining the installation position of the clamping ring assembly, determining the axial position of the housing and the upper cover plate, determining the axial position of the upper cover plate and the clamping ring body, determining the relative position of the clamping ring body and the cylindrical structural member, and finally determining the axial position of the housing and the structural member and making the central axes overlap, ensuring the shape of the cylindrical structural member and the coaxiality of the set at the same time.

[0025] When performing the set forming process, first position the upper cover plate and the shell through the positioning pins and connect and fix them through screws, so that the shell and the upper cover plate are highly coincident in the center axis; connect and fix the upper cover plate and the upper top plate; place the ring body on the working platform, at which time the ring body and the working platform can be relatively adjusted, that is, the locking mechanism does not play a locking role; place the structural parts in the inner cavity of the ring body, and the relative position of the ring body and the cylindrical structural parts is determined. It is only necessary to adjust the position of the ring assembly during the set so that the accommodating part and the protruding part are docked and matched to make the shell and the center axis of the cylindrical structural parts highly coincident. Since the connection between the upper cover plate and the upper top plate has a certain adjustment margin, it is necessary to predetermine the setting position of the ring assembly, that is, the center axis position of the shell, during the set. The setting position of the holding ring assembly can be determined through the trial assembly operation. Specifically, the upper top plate is driven down by the driving assembly, and the position of the holding ring body is adjusted so that the protrusion and the receiving part on the holding ring body and the upper cover plate are docked and slidably matched, so as to determine the docking position of the holding ring body on the working platform, and the holding ring body is locked and positioned by the locking mechanism, that is, the relative position of the holding ring assembly and the working platform will no longer change in the subsequent steps, and the position of the working platform will not change. The upper top plate is driven up by the driving assembly to separate the shell and the cylindrical structural member, and glue is applied to the inner bonding surface of the cylindrical structural member. Since the relative position of the shell and the cylindrical structural member has not changed, the upper top plate can be driven down directly by the driving assembly after applying glue, so that the shell and the cylindrical structural member can be assembled, and the curing treatment is performed to obtain the cabin section, realizing the efficient assembly of the composite material structural member of the rotating body, and solving the problems of debonding and deformation.

[0026] In summary, the present invention aims at the characteristics of the rotating composite material structural parts and their process molding methods, and designs a tooling specifically for the assembly process. The tooling is equipped with comprehensive positioning measures to avoid dimensional deviations caused by poor positioning. The entire process is controllable, the quality of the prepared products is stable, the preparation efficiency is high, and rolling production is possible, which lays a foundation for the engineering of similar cylindrical structural parts.

[0036] In order to enable those skilled in the art in the technical field to which the present application belongs to more clearly understand the present application, the technical solution of the present application will be described in detail below with reference to the drawings through specific embodiments.

[0037] In order to solve the technical problems that in the prior art, when a cylindrical structural member of a composite material is sleeved and formed with a housing, it is difficult to be in place, difficult to be positioned, easy to deform, and easy to debond, the present invention provides a special tooling for the sleeving process and a sleeving and forming method. The tooling is provided with comprehensive positioning measures, which can avoid dimensional tolerance caused by poor positioning. The whole process is controllable, the quality of the prepared product is stable, and the preparation efficiency is high. The content of the present invention will be introduced in detail below through 2 specific embodiments:

[0038] Embodiment 1

[0039] Such as Figures 1-7As shown in the figure, a tooling provided in this embodiment includes a clamping ring assembly 10, a frame 20, an upper cover plate 30, and more than 2 sets of positioning structures 40, where: The clamping ring assembly 10 includes a clamping ring body 11, and the clamping ring body 11 is provided with an inner cavity that matches the outer diameter of the cylindrical structural member 200. Thus, during the sleeving process, the outer contour surface of the cylindrical structural member 200 can be positioned and shaped, effectively controlling the outer shape of the cylindrical structural member 200 during the sleeving process, preventing its size from changing, and playing a role in controlling its relative position. The frame 20 is provided with an operation platform, an upper top plate 21, a driving assembly 22 for driving the upper top plate 21 to move up and down, and a locking mechanism 25 for fixing the clamping ring assembly 10 to the operation platform. The upper top plate 21 is located above the operation platform. The upper cover plate 30 is used to connect the upper end face of the housing 100 and the upper top plate 21. The upper top plate 21 and the housing 100 are connected to two opposite sides of the upper cover plate 30, that is, the housing 100 and the upper top plate 21 are connected as a whole through the upper cover plate 30. Taking the clamping ring assembly 10 provided on the operation platform as a reference, under the action of the driving assembly 22, the housing 100 is placed into the central hole of the cylindrical structural member 200 from top to bottom. The positioning structure 40 includes a matching protrusion 41 and a receiving portion. Among the protrusion 41 and the receiving portion, one is provided on the clamping ring body 11 and the other is provided on the upper cover plate 30. More than 2 sets of positioning structures 40 are arranged at intervals along the circumferences of the clamping ring body 11 and the upper cover plate 30 to ensure the positioning accuracy, and the axis of the positioning structure 40 is parallel to the axis of the clamping ring body 11. When the housing 100, the upper cover plate 30, and the upper top plate 21 descend together until the upper cover plate 30 approaches the upper end face of the clamping ring body 11, the receiving portion and the protrusion 41 are butted and matched, thereby determining the installation position of the clamping ring assembly 10, determining the axial positions of the housing 100 and the upper cover plate 30, determining the axial positions of the upper cover plate 30 and the clamping ring body 11, determining the relative position of the clamping ring body 11 and the cylindrical structural member 200, and finally determining the axial position of the housing 100 and the structural member and making their central axes overlap, ensuring the outer shape of the cylindrical structural member 200 and the coaxiality of the sleeving at the same time.

[0040] To ensure the unobstructed insertion of the cylindrical structural member 200 and at the same time ensure the shape control effect, as a preferred embodiment, the diameter of the inner cavity of the clamping ring body 11 is 0.1 mm to 1 mm larger than the outer diameter of the cylindrical structural member, which can effectively avoid deformation during the sleeving process.

[0041] In this embodiment, the specific structure and composition of the clamping ring assembly 10 are not limited. In some embodiments, the clamping ring body 11 with different diameters and axial lengths can be designed corresponding to different-sized cabin sections, and different clamping rings can be specifically designed for different sizes. Since the clamping ring body 11 requires a certain structural strength, the materials selected for it generally have a relatively high cost. To save costs, as a preferred embodiment, the clamping ring assembly 10 further includes a support frame 12, and the clamping ring body 11 is detachably connected to the top surface of the support frame 12; the support frame 12 is provided with support feet 13, and the locking mechanism 25 is used to position the support feet 13 on the working platform, thereby reducing the axial length of the clamping ring body 11 and reducing the material usage. In some embodiments, one support frame 12 can be used for the connection and fixation of multiple clamping ring bodies 11, and the universality of clamping ring bodies 11 with different sizes can also be satisfied by setting multiple circles of connection holes and pin holes.

[0042] In this embodiment, the specific structure of the support frame 12 is not limited either. For example, in some embodiments, the support frame 12 can be a solid structure, and in some embodiments, in order to reduce weight, facilitate handling, and control costs at the same time, the support frame 12 can also be designed as a frame structure.

[0043] In order to avoid the loss of the glue used for curing during the curing step after the cylindrical structural member 200 with a through hole in the center and the housing 100 are sleeved, in this embodiment, the tooling further includes a flow guiding member. The flow guiding member includes a connected cylindrical section and a conical section. The large-diameter end of the conical section is connected to the cylindrical section, and the outer diameter of the cylindrical section is equal to the maximum outer diameter of the conical section. The end face of the cylindrical section is used to fit the lower end face of the housing 100. The connection and fixation of the flow guiding ring to the housing 100 directly utilize the threaded holes on the end face of the housing 100 without changing the structure of the housing 100. In this embodiment, the structural shape of the flow guiding ring is not specifically limited, and the flow guiding member can be a circular plate or a circular ring.

[0044] In order to further achieve the effects of guiding the flow and reducing the loss of the glue, as a preferred embodiment, the inclination angle of the generatrix of the conical section is 0.5° - 5°; the outer diameter dimension of the flow guiding member 50 is 0.1 mm - 4 mm smaller than the outer diameter dimension of the housing 100.

[0045] In order to achieve visual observation and judgment of the proper installation of the set, as an implementation method, the tooling further includes an adapter plate 60 detachably connected to the upper end surface of the clamping ring body 11, so that the top surface of the adapter plate 60 is flush with the upper end surface of the cylindrical structural member 200. The adapter plate 60 is used to contact the upper cover plate 30, and the upper cover plate 30 is also provided with a counterbore matching the end size of the housing 100. Through size design, when there is no gap between the upper cover plate 30 and the adapter plate 60 on the clamping ring body 11, it indicates that the housing 100 and the cylindrical structural member 200 are properly installed, realizing the visualization of the measurement standard. It should be noted that the depths of the counterbores corresponding to different cabin sections are also different, and specific adaptive adjustments are made according to the design requirements of the cabin section and the installation size requirements. No specific limitation is made in this embodiment.

[0046] In order to prevent the installation problems caused by the rotation or axial movement of the cylindrical structural member 200 due to environmental vibration or interference during the installation process, in this embodiment, the number of adapter plates 60 is at least two, and the at least two adapter plates 60 are arranged at intervals along the circumferential direction of the clamping ring body 11, that is, within the circumferential range of the clamping ring body 11, the coverage range of the adapter plates 60 is less than 360°. The tooling further includes at least one pressing block 70, and the pressing block 70 is detachably arranged on the upper end surface of the clamping ring body 11 for pressing the cylindrical structural member 200 and positioning the cylindrical structural member 200, thereby effectively preventing the circumferential rotation and quadrant misalignment of the cylindrical structural member 200.

[0047] Since the lower end surface of the upper cover plate 30 needs to contact the top surface of the adapter plate 60, but the height of the pressing block 70 is necessarily higher than that of the adapter plate 60. In order to ensure the visualization effect of the proper installation of the upper cover plate 30 and the adapter plate 60, in this embodiment, the upper cover plate 30 is also provided with a notch to avoid interfering with the installation of the pressing block 70.

[0048] This embodiment does not specifically limit the setting method of the positioning structure 40. Each accommodating part and protruding part 41 of the positioning structure 40 can have two setting methods, that is, the accommodating part is arranged on the upper cover plate 30 or the protruding part 41 is arranged on the upper cover plate 30. Therefore, when there are more than 2 positioning structures 40, there are at least 4 setting forms.

[0049] In order to save space and effectively utilize the characteristics of the installation, as an implementation method, the protruding parts 41 are all arranged on the upper end surface of the clamping ring body 11, the protruding parts 41 are positioning pins, and the accommodating parts are pin holes on the upper cover plate 30.

[0050] This embodiment does not specifically limit the cooperation method between the protruding part 41 and the adapter plate 60. In some implementation methods, the protruding part 41 can be offset from the position of the adapter plate 60, that is, the protruding part 41 only cooperates and is arranged in the accommodating part. In some implementation methods, through holes for the protruding part 41 to pass through can also be arranged on the adapter plate 60, and after the protruding part 41 passes through the through holes, it cooperates with the accommodating part.

[0051] This embodiment does not specifically limit the setting form of the working platform on the frame 20. For example, in some embodiments, the working platform is integrally formed with the frame 20. At this time, after determining the position of the clamping ring assembly 10 through trial fitting before gluing, the clamping ring assembly 10 and the cylindrical structural member 200 cannot be moved anymore. At this time, glue brushing operation needs to be carried out within the space of the frame 20. In order to avoid the difficulty of glue brushing caused by the limited space of the frame 20, in some embodiments, the frame 20 is provided with an installation platform 26, and the tooling further includes a lower bottom plate 27. The lower bottom plate 27 and the installation platform 26 are movably connected by positioning pins; the lower bottom plate 27 constitutes the working platform, and a locking mechanism 25 is arranged on the lower bottom plate 27. So that when gluing, the positioning pins between the lower bottom plate 27 and the installation platform 26 can be removed, and the lower bottom plate 27 and the clamping ring assembly 10 fixed to the lower bottom plate 27 by the locking mechanism 25 can be integrally removed, which is convenient for glue brushing. And when formally assembling, the positions of the lower bottom plate 27 and the installation platform 26 are the same as those during trial fitting under the action of the positioning pins, ensuring that the positions of the clamping ring assembly 10 and the cylindrical structural member 200 remain unchanged during the formal assembly and trial fitting processes, and direct unobstructed assembly can be carried out, which is beneficial to improving the process efficiency.

[0052] In some embodiments, such as Figure 1 and Figure 3 shown, in order to facilitate the insertion and removal of the lower bottom plate 27 and the clamping ring assembly 10, a slide rail 28 is arranged on the installation platform 26, and the lower bottom plate 27 is slidably matched with the slide rail 28, so that when gluing, the lower bottom plate 27 and the workpieces thereon can be pulled out as a whole, and after the glue brushing is completed, it is pushed back into the interior of the frame 20, and the position is ensured to be the same as that during trial fitting through the positioning pins.

[0053] In order to ensure the perpendicularity in the vertical direction during assembly, the frame 20 is provided with a horizontal adjustment mechanism 29 to make the installation platform 26 and structures such as the drive assembly 22 and the upper top plate 21 on the installation platform 26 be horizontally placed or move vertically.

[0054] This embodiment does not specifically limit the specific implementation manner of the drive assembly 22. For example, in some embodiments, it can be a purely electric control automation mechanism. In some embodiments, it can also be a lifting mechanism controlled manually. As a preferred embodiment, in order to achieve the combination of electric control and manual operation, by manually controlling the lifting speed to ensure the assembly quality and avoid a series of problems caused by too large impact force. In this embodiment, as Figure 1 shown, the drive assembly 22 includes an electrically controlled transmission mechanism 23 and a manually controlled pressure application mechanism 24. Both the transmission mechanism and the pressure application mechanism can control the lifting of the upper cover plate 30. For example, the transmission mechanism can be a ball screw pair or a linear motor, etc., and the transmission mechanism is guidingly matched with the upper top plate 21; the pressure application mechanism can be a worm and worm wheel mechanism of a hand crank type.

[0055] It should be noted that, in order to avoid over-positioning, in this embodiment, preferably, there is a certain adjustment margin in the connection and fixation between the upper top plate 21 and the upper cover plate 30. For example, the size of the threaded hole can be slightly larger than the size of the bolt, so as to avoid over-positioning caused by direct positioning of the upper cover plate 30 and the upper top plate 21, and direct positioning of the clamping ring assembly 10 and the working platform through the positioning pin.

[0056] This embodiment does not limit the optional solutions of the locking mechanism 25. For example, in some embodiments, the locking mechanism 25 can be a plurality of screw-type telescopic adjustment members fixed to the working platform and distributed circumferentially around the clamping ring assembly 10. After determining the position, the clamping ring assembly 10 can be positioned by the action of the plurality of screw-type telescopic adjustment members on the circumferential surface of the clamping ring assembly 10. In this embodiment, the locking mechanism 25 is a positioning block similar to the working principle of the pressing block 70. The positioning block is detachably connected to the working platform. When it is necessary to fix the clamping ring assembly 10, the positioning block is fixedly connected to the working platform. The foot plate of the clamping ring assembly 10 is arranged between the positioning block and the working platform, and the positioning block presses the foot plate against the working platform, restricting the movement of the clamping ring assembly 10.

[0057] As Figure 1 and Figure 3 shown, in order to improve the versatility of the rack and enable the rack to be used for the assembly of cabin sections of different sizes, as shown in the figure, in this embodiment, the locking mechanism 25 includes a plurality of positioning blocks arranged at intervals on the lower bottom plate, and several of the positioning blocks can be selectively used to press the support foot plate of the support frame.

[0058] In the tooling provided by this embodiment, the rack 20 is used to assist the entire sleeving process. Among them, the upper top plate 21 and the upper cover plate 30 are connected by screws. The upper top plate 21 is not a mechanically welded fixed structure, and the connected upper cover plate 30 can be slightly adjusted. After the foot plate of the clamping ring bracket is positioned by the locking mechanism 25 with the lower bottom plate 27, they cannot move relative to each other. The lower bottom plate 27, that is, the working surface, is connected to the large working surface of the entire device by a positioning pin to ensure its horizontality and positioning. This structure can ensure that the clamping ring is in a horizontally controllable position. Since the upper cover plate 30 and the housing 100 can be slightly adjusted as a whole, the end face of the clamping ring is used as the reference in the sleeving process. As Figure 7 shown, the rack 20 can be used for the sleeving of different products to form a rolling production.

[0059] Embodiment 2

[0060] Based on the same inventive concept, this embodiment provides a sleeving and forming method implemented based on the tooling in Embodiment 1. The sleeving and forming method includes the following steps:

[0061] The upper cover plate 30 and the housing 100 are positioned by positioning pins and fixedly connected by screws, so that the central axis heights of the housing 100 and the upper cover plate 30 coincide; the upper cover plate 30 is fixedly connected to the upper top plate 21; the loop body 11 is placed on the operating platform, and the structural member is placed into the inner cavity of the loop body 11; at this time, the loop body 11 and the operating platform can be adjusted relative to each other in position, that is, the locking mechanism 25 does not play a locking role; the structural member is placed into the inner cavity of the loop body 11, and the relative positions of the loop body 11 and the cylindrical structural member 200 are determined. Only by adjusting the position of the loop assembly 10 during the sleeving process to make the accommodating portion and the protruding portion 41 dock and cooperate can the central axis heights of the housing 100 and the cylindrical structural member 200 coincide.

[0062] Since there is a certain adjustment margin in the connection between the upper cover plate 30 and the upper top plate 21, it is necessary to pre-determine the installation position of the loop assembly 10, that is, the central axis position of the housing 100 during the sleeving process. The installation position of the loop assembly 10 can be determined through trial sleeving operations. Specifically, during trial sleeving positioning, the upper top plate 21 is driven to descend by the driving assembly 22, and the position of the loop body 11 is adjusted so that the protruding portion 41 and the accommodating portion on the loop body 11 and the upper cover plate 30 are docked and slidably cooperate, thereby determining the docking position of the loop body 11 on the operating platform, and the loop body 11 is locked and positioned by the locking mechanism 25; that is, the relative position between the loop assembly 10 and the operating platform will no longer change in the subsequent steps.

[0063] The driving assembly 22 is used to drive the upper top plate 21 to rise so that the housing 100 and the cylindrical structural member 200 are separated, and glue is brushed on the inner bonding surface of the cylindrical structural member 200;

[0064] The driving assembly 22 is used to drive the upper top plate 21 to descend, the housing 100 and the cylindrical structural member 200 are sleeved, and a curing treatment is performed to obtain a cabin section. Since the relative positions of the housing 100 and the cylindrical structural member 200 have not changed, the efficient sleeving of the composite structure of the rotating body is realized, and the problems of debonding and deformation are solved.

[0065] In order to ensure the bonding quality of the adhesive curing and improve the comprehensive quality of the finished product, in this embodiment, during the process of sleeving the housing 100 and the cylindrical structural member 200 and performing the curing treatment, the sleeving forming method further includes paying attention to the amount of glue at multiple circumferential (circumferential) positions during the sleeving process. If there is no excess glue bulging, it is supplemented to ensure that the excess circumferential glue can be adsorbed into the gap due to the formation of negative pressure caused by the change in the gap during the sleeving process, and the gap between them is filled.

[0066] In order to make the quality of the obtained cabin section stable and further solve the problems of debonding and deformation, in this embodiment, the fixed adhesive is selected as a silicon-based set adhesive. The silicon-based set adhesive has great differences in composition, viscosity, and process window from the traditional set adhesive. Although its viscosity is relatively large, resulting in process difficulties, it has the ability to coordinate strain at high temperatures. The process window of the set adhesive is 5 minutes to 60 minutes, which can be adjusted according to the ratio of the adhesive, and the adhesive can be replenished at any time during the process.

[0067] In summary, the set forming method provided in this embodiment, based on the specific steps implemented in Embodiment 1, is as follows:

[0068] (1) Use the horizontal leveling mechanism to adjust both the working platform and the installation platform 26 of the entire frame 20 to be horizontal. Then, push the lower bottom plate 27 into the frame 20 along the slide rail 28, and position the working platform and the installation platform 26 with positioning pins.

[0069] (2) Connect the upper cover plate 30 and the housing 100 with screws and insert positioning pins, and then connect the upper cover plate 30 and the upper top plate 21. Place the support frame 12 on the lower bottom plate 27. At this time, there is no need to provide the locking mechanism 25 to lock the support frame 12, and then place the structural member into the inner cavity of the holding ring body 11.

[0070] (3) Start the motor of the drive assembly 22, and slowly lower the upper top plate 21 connected to the housing 100. During this process, the position of the holding ring assembly 10 can be appropriately adjusted so that the housing 100 can fall into the structural member. According to the positions of the housing 100 and the upper cover plate 30, adjust the relative position of the holding ring assembly 10. When the positioning pin on the end face of the holding ring body 11 can be inserted into the pin hole of the upper cover plate 30 for sliding fit, slowly lower the housing 100 so that the upper cover plate 30 contacts the adapter plate 60. If there is no obstruction and no stress between them during the whole process, the support frame 12 can be fixed and locked by the locking mechanism 25. At this time, the trial fitting is completed.

[0071] (4) After raising the housing 100 from the structural member, the holding ring assembly 10 and the lower bottom plate 27 can be slid out of the frame 20 together to facilitate brushing the adhesive.

[0072] (5) After brushing the adhesive, the lower bottom plate 27 can be slid into the frame 20 along the slide rail 28, and repeat the trial fitting steps. Lower the housing 100 until the lower cover plate contacts the adapter plate 60 without gaps. Observe the adhesive situation at any time during the set fitting process and replenish it at any time. After the set fitting is in place, the upper cover plate 30 and the adapter plate 60 can be connected with screws, and at this time, it becomes a fixed whole. After the screws are locked, the screws between the upper top plate 21 and the upper cover plate 30 can be removed. This whole can be taken off from the lower bottom plate 27, and then the frame 20 can be used for the set fitting of other products to form a rolling production.

[0073] In view of the characteristics of the composite structural parts of the rotating body and its process forming method, a special tooling for the sleeving process is designed. The tooling is provided with comprehensive positioning measures, which can avoid dimensional tolerance caused by poor positioning. The whole process is controllable, the quality of the prepared products is stable, the preparation efficiency is high, and rolling production can be carried out. Through the above steps, the efficient sleeving of the composite structural parts of the rotating body is realized, the problems of debonding and deformation are solved, and a foundation is laid for the engineering of similar cylindrical structural parts 200.
