Description

Technical Field

[0001] This invention belongs to the field of compartment processing technology, and in particular relates to an anti-deformation tooling. Background Technology

[0002] In the field of aerospace manufacturing and launch, rocket modules are mostly large-sized, thin-walled cylindrical shell structures. As launch vehicles develop towards larger diameters and lighter weights, the wall thickness of modules is constantly decreasing, and the overall structural rigidity is reduced. During module transfer, factory turnover, and long-distance transportation, vibrations and impact loads caused by road bumps can easily lead to plastic deformation of the modules, affecting subsequent assembly accuracy and product quality. Therefore, it is usually necessary to install support fixtures inside the modules to suppress structural deformation.

[0003] Currently available anti-deformation tooling for cabin support suffers from several drawbacks, including reliance on manual operation. Furthermore, once locked, existing tooling is mostly statically fixed and lacks the ability to dynamically maintain support. During transport, continuous vibration and impact loads can cause the pre-tightening of the support structure to weaken, leading to gaps and relative displacement between the support end and the cabin wall. This makes it difficult to maintain a stable support state and effectively resist dynamic loads during transport, resulting in insufficient reliability and stability in preventing deformation. The locking and releasing of the tooling largely relies on manual bolt tightening, lacking an integrated drive and adjustment structure. This cumbersome process requires significant manpower, severely hindering the efficiency of cabin transport in high-efficiency environments such as launch sites. Additionally, manual operation cannot precisely quantify and control the support force, easily leading to insufficient support causing cabin movement and collisions, or excessive support damaging thin-walled cabin walls. Furthermore, since most of the tooling is a rigid support structure with fixed dimensions, it can only be adapted to compartments with a single diameter. When the compartment model or diameter changes, the support radius cannot be adjusted, and the entire set of tooling must be redesigned and manufactured. This results in poor versatility and high operating costs. Some adjustable tooling uses multiple support rods for independent adjustment, lacking a centralized transmission synchronous adjustment structure. The adjustment process requires operation on each support point one by one, resulting in low work efficiency and difficulty in ensuring synchronous expansion and contraction of each support point. This can easily cause uneven stress on the inner wall of the compartment and lead to local deformation.

[0004] Therefore, it is necessary to design a deformation-resistant tooling to overcome the above problems. Summary of the Invention

[0005] To address the technical problems mentioned in the background art, such as existing tooling being mostly statically fixed after locking, lacking the ability to dynamically maintain resistance, and relying on manual adjustment, a deformation-resistant tooling is provided.

[0006] To achieve the above objectives, the specific technical solution of the anti-deformation tooling of the present invention is as follows: An anti-deformation tooling, installed on the inner wall of a compartment, characterized in that it comprises: A central block, wherein a first transmission unit is provided inside the central block, and at least two through holes communicating with the interior of the central block are provided on the side wall of the central block; A support assembly corresponding to each of the through holes includes a support rod, a second transmission unit, and a supporting unit. The second transmission unit is disposed at one end of the support rod, and the supporting unit is disposed at the other end of the support rod. The second transmission unit is located inside the central block and is connected to the first transmission unit. One end of the support rod extends into the interior of the central block through the through hole. When the first transmission unit drives the second transmission unit to move, it drives the support rod to move, thereby moving the supporting unit closer to or away from the central block. A drive assembly is connected to the first transmission unit and is used to transmit driving force to the first transmission unit. When the first transmission unit is activated, it drives the second transmission unit to activate, thereby causing the abutment unit to move towards or away from the inner wall of the compartment via the support rod.

[0007] Furthermore, an even number of through holes are provided, and the through holes are orthogonally arranged on the peripheral side surface of the central block.

[0008] Furthermore, the anti-deformation tooling also includes a mounting base, a drive assembly disposed inside the mounting base, the central block being square, and the mounting base being located on the upper or lower side of the central block.

[0009] Furthermore, the mounting base includes: A receiving base is provided with a receiving cavity, and a driving component is disposed in the receiving cavity of the receiving base. The output end of the driving component extends out of the receiving cavity and is connected to the first transmission unit inside the central block. A connecting piece is disposed on the periphery of the opening of the receiving base; the receiving base is mounted on the central block via the connecting piece.

[0010] Furthermore, the support rod includes a first rod body, a second rod body, and an anti-rotation baffle. The second transmission unit is disposed at one end of the first rod body, and the abutment unit is disposed at one end of the second rod body. The first rod body and the second rod body are coaxial, and the other end of the first rod body and the other end of the second rod body are threadedly connected to each other. The anti-rotation baffle is installed on the center block and cooperates with the second rod body, so that the second rod body can slide relative to the first rod body along the axial direction and restricts the second rod body from rotating around its own axis.

[0011] Furthermore, the support assembly also includes a first bearing installed in the through hole, the outer ring of the first bearing abutting against the inner wall of the through hole, and the inner ring of the first bearing sleeved on the outer side of the first rod body.

[0012] Furthermore, the first rod is configured as a screw, the second rod is configured with a threaded sleeve, the first rod is connected to the second transmission unit, and the support assembly also includes a stop nut, the stop nut is threadedly installed on the first rod and fixed to the side wall of the center block, the stop nut is coaxially arranged with the through hole, and at least one stop nut is provided for each through hole.

[0013] Furthermore, the first transmission unit includes a first bevel gear, the second transmission unit includes a second bevel gear, the second bevel gears are respectively connected to the corresponding support rods, and the first bevel gear simultaneously engages with multiple second bevel gears; The support assembly also includes a second bearing and a clutch assembly. The second bearing is connected to the first rod and the second bevel gear, respectively. The clutch assembly includes a clutch base, a telescopic boss, and a stop plate. The clutch base is connected to the first rod. The telescopic boss is telescopically mounted on the clutch base. The second bevel gear is provided with an insertion groove corresponding to the telescopic boss. The telescopic boss can extend into or disengage from the insertion groove to connect the clutch base with the second bevel gear. The stop plate abuts against the clutch base and the second bevel gear, respectively.

[0014] Furthermore, the end face of the supporting unit away from the support rod is an arc-shaped surface, and a sheet-like anti-slip pad is attached to the arc-shaped surface.

[0015] Furthermore, the abutment unit also includes a pressure sensor disposed between the anti-slip pad and the arc-shaped surface, for detecting the pressure of the abutment unit relative to the inner wall of the compartment.

[0016] The anti-deformation tooling of this invention has the following advantages: Through the structure of a central block housing a first transmission unit and a single drive assembly synchronously driving multiple sets of second transmission units, synchronous radial extension and retraction of multiple support rods under a single power input is achieved, ensuring consistent adjustment at each support point and uniform stress on the inner wall of the compartment, avoiding localized deformation caused by uneven loading. The support rods can flexibly adjust their extension length radially, adapting to compartments of different diameters, eliminating the need for customized tooling for single-model compartments, significantly improving tooling versatility and reducing tooling costs for multi-model production. Furthermore, the drive assembly enables mechanized locking and releasing, replacing traditional manual bolt tightening operations, greatly reducing operation time and improving the efficiency of compartment transfer operations. In practical applications, the transmission adjustment ensures that the supporting unit always abuts against the inner wall of the compartment, dynamically maintaining the support state under transportation vibration and impact conditions, preventing support loosening and gaps, and continuously ensuring the anti-deformation effect.

[0026] The following is a reference to the appendix. Figure 1 To be continued Figure 4 This invention describes an anti-deformation tooling.

[0027] This embodiment provides an anti-deformation tooling, which is installed on the inner wall of a compartment, such as... Figure 1 and Figure 2As shown, the anti-deformation tooling includes a central block 1, a support assembly 2, and a drive assembly 3. The central block 1 has a first transmission unit 11 inside, and at least two through holes communicating with the interior of the central block 1 are provided on its side wall. The support assembly 2, corresponding to each through hole, includes a support rod 21, a second transmission unit 11, and a supporting unit 23. The second transmission unit 22 is located at one end of the support rod 21, and the supporting unit 23 is located at the other end of the support rod 21. The second transmission unit 22 is located inside the central block 1 and is connected to the first transmission unit 11. One end of the support rod 21 extends into the interior of the central block 1 through the through hole. When the first transmission unit 11 drives the second transmission unit 22, it drives the support rod 21 to move, causing the supporting unit 23 to move closer to or away from the central block 1. The drive assembly is connected to the first transmission unit and transmits driving force to the first transmission unit 11. When the first transmission unit 11 moves, it drives the second transmission unit 22 to move, thereby causing the supporting unit 23 to move closer to or away from the inner wall of the compartment via the support rod 21.

[0028] It is understandable that by using the structure of the first transmission unit 11 built into the central block 1 and the single drive component 3 to synchronously drive multiple sets of second transmission units 22, the synchronous radial extension and retraction of multiple support rods 21 under a single power input can be achieved, ensuring that the adjustment amount of each support point is consistent, the inner wall of the compartment is subjected to uniform force, and avoiding local deformation caused by off-center loading; the support rods 21 can flexibly adjust the extension length along the radial direction, which can be adapted to compartments of different diameter specifications, eliminating the need for customized tooling for a single model of compartment, significantly improving the versatility of tooling, and reducing the tooling cost for multi-model production.

[0029] It should be noted that the mechanical locking and releasing is achieved by relying on the drive component 3, which replaces the traditional manual bolt tightening operation, greatly reducing the operation time and improving the efficiency of compartment transfer operation. In actual application, the support unit 23 can be kept against the inner wall of the compartment by transmission adjustment, and can dynamically maintain the support state under transportation vibration and impact conditions, avoiding the support from loosening and gaps, and continuously ensuring the anti-deformation effect.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, an even number of through holes are provided, and the through holes are orthogonally arranged on the peripheral side surface of the central block 1. In this embodiment, four through holes are provided, distributed in pairs on the side surface of the central block 1.

[0031] Understandably, the structure with an even number of orthogonally symmetrical through holes allows the support components 2 to be evenly and symmetrically distributed along the circumference of the compartment, forming a symmetrical multi-point support system. The support force is evenly transmitted to the inner wall of the compartment in the radial direction, avoiding the compartment from deforming due to asymmetrical force. At the same time, the multi-point orthogonal support structure has better overall stiffness, stronger vibration and impact resistance, and higher stability of the tooling itself during transportation.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, the anti-deformation tooling also includes a mounting base 4, a drive assembly 3 is disposed inside the mounting base 4, the center block 1 is square, and the mounting base 4 is located on the upper or lower side of the center block 1.

[0033] Understandably, the independently designed mounting base 4 provides a closed installation space for the drive assembly 3, which can provide physical protection for the drive components and reduce damage to the drive assembly 3 caused by dust and impacts during transportation.

[0034] It should be noted that setting the center block 1 as a square structure facilitates the planar positioning and assembly of the mounting base 4. The way the mounting base 4 is arranged on the upper and lower sides of the center block 1 makes reasonable use of the axial space of the tooling, does not occupy the radial adjustment stroke of the support rod 21, and facilitates the wiring and daily maintenance of the drive component 3.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the mounting base 4 includes a receiving base 41 and a connecting piece 42. The receiving base 41 is provided with a receiving cavity. The driving assembly 3 is disposed in the receiving cavity of the receiving base 41. The output end of the driving assembly 3 extends out of the receiving cavity and is connected to the first transmission unit 11 inside the center block 1. The connecting piece 42 is disposed on the periphery of the opening position of the receiving base 41. The receiving base 41 is mounted on the center block 1 through the connecting piece 42.

[0036] Understandably, the receiving cavity of the receiving base 41 can semi-enclose the drive component 3, effectively isolating it from external dust, moisture and impact, and extending the service life of the drive components; the connecting piece 42 on the periphery enables the detachable fixing of the mounting base 4 and the center block 1, making assembly and disassembly operations convenient, and eliminating the need to disassemble the internal transmission structure when inspecting or replacing the drive component 3 in the future, resulting in low maintenance costs.

[0037] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the support rod 21 includes a first rod body 211, a second rod body 212, and an anti-rotation baffle 213. The second transmission unit 22 is disposed at one end of the first rod body 211, and the abutment unit 23 is disposed at one end of the second rod body 212. The first rod body 211 and the second rod body 212 are coaxial, and the other end of the first rod body 211 and the other end of the second rod body 212 are threadedly connected to each other. The anti-rotation baffle 213 is installed on the center block 1 and cooperates with the second rod body 212 so that the second rod body 212 can slide relative to the first rod body 211 along the axial direction and restrict the second rod body 212 from rotating around its own axis.

[0038] Understandably, the support rod 21 adopts a split rod structure with threaded connection, which can stably convert the rotational motion of the second transmission unit 22 into the axial linear extension and retraction motion of the support rod 21. The transmission is smooth and the adjustment accuracy is high, which makes it easy to accurately control the support radius. At the same time, the threaded structure has mechanical self-locking characteristics, which can maintain the support length by itself after the support is in place, reduce the length movement under transportation vibration, and improve the stability of the support state.

[0039] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the support assembly 2 also includes a first bearing 24 installed in the through hole, the outer ring of the first bearing 24 abutting against the inner wall of the through hole, and the inner ring of the first bearing 24 sleeved on the outer side of the first rod 211.

[0040] Understandably, the first bearing 24 installed in the through hole can provide radial positioning and support for the support rod 21, significantly reducing the frictional resistance during the rotation of the support rod 21 and improving transmission efficiency and adjustment smoothness; at the same time, it limits the radial movement of the support rod 21, ensuring that the support rod 21 always extends and retracts along the preset axis, avoiding deviation of the support position, and ensuring the fitting accuracy and force uniformity between the abutment unit 23 and the inner wall of the compartment.

[0041] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the first rod 211 is configured as a screw, and the second rod 212 is configured with a threaded sleeve. The first rod 211 is connected to the second transmission unit 22. The support assembly 2 also includes a stop nut 25. The stop nut 25 is threadedly installed on the first rod 211 and fixed to the side wall of the center block 1. The stop nut 25 is coaxially arranged with the through hole, and at least one stop nut 25 is provided for each through hole.

[0042] Understandably, the stop nut 25 fixed to the side wall of the central block 1 forms a threaded pair with the screw, which can help bear axial and radial loads, share the force of the first bearing 24, and significantly improve the overall load-bearing strength of the support structure. At the same time, the stop nut 25 and the screw thread form a double self-locking structure, which can reliably lock the axial position of the support rod 21 after the drive stops, effectively preventing the support rod 21 from retracting and the support force from weakening due to transportation vibration, and further ensuring the stability and deformation resistance of the support.

[0043] Furthermore, the first transmission unit 11 includes a first bevel gear, and the second transmission unit 22 includes a second bevel gear. The second bevel gears are respectively connected to the corresponding support rods 21, and the first bevel gears simultaneously engage with multiple second bevel gears.

[0044] Understandably, by adopting a bevel gear meshing transmission, the axial rotational power of the drive assembly 3 can be efficiently converted into the radial rotational power of multiple support rods 21, achieving single-input, multi-output synchronous transmission with precise transmission ratio and good synchronization of extension and retraction of support rods 21 in all directions. The bevel gear transmission has strong load-bearing capacity and smooth operation, and is not prone to tooth skipping or tooth loss under transportation vibration conditions, resulting in high transmission reliability and adaptability to the complex working conditions of aerospace compartment transportation.

[0045] Specifically, the support assembly 2 also includes a second bearing 26 and a clutch assembly 27. The second bearing 26 is connected to the first rod 211 and the second bevel gear respectively. The clutch assembly includes a clutch base 271, a telescopic boss 272 and a stop plate 273. The clutch base 271 is connected to the first rod 211. The telescopic boss 272 is telescopically mounted on the clutch base 271. The second bevel gear is provided with an insertion groove corresponding to the telescopic boss 272. The telescopic boss 272 can extend into or disengage from the insertion groove so that the clutch base 271 is connected to the second bevel gear. The stop plate 273 abuts against the clutch base 271 and the second bevel gear respectively.

[0046] Furthermore, the end face of the supporting unit 23 away from the support rod 21 is an arc-shaped surface, and a sheet-like anti-slip pad is attached to the arc-shaped surface.

[0047] Understandably, the arc-shaped end face of the supporting unit 23 can form a surface contact with the inner curved surface of the cylindrical compartment, greatly increasing the contact area, reducing the pressure per unit area, and preventing the thin-walled compartment from developing indentations or plastic deformation due to excessive local pressure. The anti-slip pad attached to the arc-shaped surface can increase the friction between the supporting unit 23 and the inner wall of the compartment, preventing the tooling and the compartment from sliding relative to each other in the circumferential and axial directions during transportation, while also preventing hard metal contact from scratching the inner wall of the compartment and protecting the product surface.

[0048] Furthermore, the abutment unit 23 also includes a pressure sensor, which is disposed between the anti-slip pad and the curved surface, for detecting the pressure of the abutment unit 23 relative to the inner wall of the compartment.

[0049] Understandably, the pressure sensor integrated into the support unit 23 can detect the support force value in real time and accurately, realize the quantitative control of the support force, and make it easy to control the support force within a reasonable range, so as to avoid insufficient support force causing compartment movement or excessive support force damaging the bulkhead. At the same time, the pressure data can provide feedback for dynamic adjustment, and in conjunction with the drive component 3, it can realize automatic compensation of the support force. When the pressure fluctuates during transportation, the stroke of the support rod 21 is automatically adjusted to maintain a stable support state, and comprehensively ensure the structural safety and positional accuracy of the compartment transportation.

[0050] The following uses the inner wall of a compartment as an example to illustrate the use of the anti-deformation tooling in this implementation: First, the pre-adjustment stage: Before the tooling is placed into the compartment, the control unit controls the drive component 3 to rotate in reverse, causing each support component 2 to retract synchronously, so that the overall outer diameter of the tooling is smaller than the inner diameter of the compartment, making it easier to place the tooling into the designated position inside the compartment.

[0051] After the tooling is in place, the target support pressure value is preset in the control unit. After the locking program is started, the drive component 3 automatically drives the support component 2 to extend. When the pressure sensor detects that the real-time pressure reaches the set threshold, the control unit controls the drive component 3 to stop automatically, thus completing the automatic locking.

[0052] Subsequently, during the transport of the compartment, the tooling is in a monitoring standby state, and the pressure sensor continuously collects support pressure data. When the support pressure deviates from the set range due to factors such as transport vibration and impact, the control unit automatically adjusts the operation of the drive component 3: if the pressure is lower than the set lower limit, the drive support component 2 extends slightly to compensate for the support stroke; if the pressure is higher than the set upper limit, the drive support component 2 retracts slightly to release the overload pressure, so that the support pressure is always maintained within the preset range, ensuring that the abutment unit 23 always abuts against the inner wall of the compartment, continuously providing stable inner wall support for the compartment and suppressing plastic deformation of the compartment.

[0053] After transportation is completed, the control unit controls the drive assembly 3 to rotate in reverse, causing each support assembly 2 to retract synchronously; when the pressure sensor detects that the support pressure has returned to zero, and confirms that the holding unit 23 is completely separated from the inner wall of the compartment, the tooling can be removed from the compartment to complete the operation.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
