Description

Technical Field

[0001] This invention relates to the field of projectile assembly technology, and in particular to a module stringing tooling that can realize module stringing and pressure curing to ensure coaxiality between modules. Background Technology

[0002] In the assembly of projectile and rocket damage units, modules need to be filled into the shell. Usually, one module is filled in sequentially. After the module is put into the shell, it needs to be pressed and held for a certain period of time to ensure effective curing.

[0003] Due to the large number of modules, multiple filling and curing processes are required during the assembly, significantly increasing filling time and reducing production efficiency. After the modules are installed in the housing, the coaxiality between modules is difficult to observe, control, and adjust in the confined space, and the coaxiality fluctuates within a large range, easily affecting the overall assembly quality characteristics.

[0004] Therefore, in the pre-processing stage before the modules are loaded into the housing, how to provide a module stringing tool to bond all the filling modules together to form a module string, and ensure the coaxiality between the modules, and then fill and cure in one go to improve production efficiency, is a technical problem that urgently needs to be solved by those skilled in the art.

One set of rod assemblies is configured to rotate around the overall center and drive the other set of rod assemblies to perform synchronous radial movement through a linkage structure, so as to achieve centering clamping or release of the module string. The pressure curing mechanism is detachably mounted on the support frame and is used to apply axial holding pressure to the module string in the clamped state.

[0007] Preferably, the support frame includes an upper rotating base plate, a lower rotating base plate, a circular bottom plate, and multiple fixed support rods; the two ends of the fixed support rods are fixedly connected to the upper rotating base plate and the lower rotating base plate respectively, and the circular bottom plate is fixedly connected to the lower rotating base plate by support columns.

[0008] Preferably, the rotary drive mechanism includes an upper rotary slider, a lower rotary slider, and multiple movable support rods; the upper rotary slider and the lower rotary slider are slidably mounted on the upper rotary base plate and the lower rotary base plate, respectively; the two ends of the movable support rods pass through the waist holes on the upper rotary base plate and the lower rotary base plate, respectively, and are fixedly connected to the upper rotary slider and the lower rotary slider, forming a movable cage that can rotate around the overall center.

[0009] Preferably, the synchronous radial clamping mechanism includes multiple radial clamping rods, a clamping and retracting slider, and a connecting rod slider; both ends of the radial clamping rods are fixedly connected to the clamping and retracting sliders respectively, the clamping and retracting sliders are movably connected to the connecting rod sliders through clamping and retracting pins, the connecting rod sliders are movably connected to the upper rotating slider and the lower rotating slider respectively through connecting rod pins, the connecting rod pins pass through the waist holes on the upper rotating base plate and the lower rotating base plate, and are connected to the upper rotating base plate and the lower rotating base plate through tension springs.

[0010] Preferably, the radial clamping rods are three in number, evenly distributed in a circle, and their contact with the module string is a line contact.

[0015] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects: This application provides a modular stringing fixture that achieves circumferential synchronous centering and clamping of the modular string through a mechanism where the rotation of a movable cage drives the synchronous centripetal movement of a radial clamping rod. Compared to the random errors during traditional manual single-module loading, this fixture utilizes the rigidity and synchronicity of the mechanical structure to forcibly correct the module position, controlling the coaxiality between modules within a very small tolerance range. This effectively solves the problem of difficulty in observing and adjusting coaxiality in confined spaces, significantly improving the overall assembly quality characteristics of the projectile damage unit.

[0016] This tooling allows multiple modules to be pre-bonded together, simplifying the subsequent shell filling process from the traditional multiple fillings and multiple pressing and curing to a single filling and single pressure curing. This change in process mode eliminates the time wasted on repeatedly disassembling and assembling tooling and waiting for curing, significantly shortening the production cycle, and is especially suitable for batch assembly operations of multi-module series structures.

[0017] The design employs a three-bar circular structure, eliminating the blind spots inherent in closed molds. The gaps between the bars provide operators with a good viewing angle, facilitating real-time monitoring of the adhesive layer status and module alignment during bonding, and allowing for immediate fine-tuning. Simultaneously, the radial clamping bars utilize line contact with the module surface, resulting in less friction compared to surface contact. Furthermore, the bars automatically reposition themselves when released, allowing for easy removal of the cured module string and preventing demolding damage.

[0018] The pressure cap assembly employs a ball joint design, converting rotational motion into pure axial linear motion. This design completely eliminates the tangential friction that may occur during the tightening process of traditional rigid pressure heads, preventing relative rotation or surface wear of the modules during pressure application, and ensuring the stability of the pressure curing process and the structural integrity of the module string.

[0019] By configuring an inner membrane with a contoured cavity, the tooling can adapt to irregularly shaped modules with non-standard heads. The inner membrane provides precise positioning and horizontal support for the module head, ensuring accurate baseline positioning of the first module, thereby guaranteeing the verticality and straightness of the entire string of modules and expanding the applicability of the tooling. Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The module stringing fixture provided in this application uses three sets of straight rods forming a circle, which is convenient for observation and adjustment. All contact with the modules is line contact, which facilitates the removal of the module string from the mold. One set of straight rods is connected to a cage that can rotate around the overall center, which drives the other set of straight rods to move radially synchronously, clamping the modules synchronously and ensuring the coaxiality between the modules.

[0026] In a specific implementation, the support frame provided in this embodiment includes an upper rotating base plate 4, a lower rotating base plate 14, a circular bottom plate 19, and multiple fixed support rods 12; the two ends of the fixed support rods 12 are fixedly connected to the upper rotating base plate 4 and the lower rotating base plate 14 respectively, and the circular bottom plate 19 is fixedly connected to the lower rotating base plate 14 below by support columns 18.

[0028] The synchronous radial clamping mechanism includes multiple radial clamping rods 11, a clamping and retracting slider 6, and a connecting rod slider 5.

The connecting rod pin 7 passes through the waist holes on the upper rotating base plate 4 and the lower rotating base plate 14, and is connected to the upper rotating base plate 4 and the lower rotating base plate 14 through a tension spring 9.

[0029] The radial clamping rods 11 are three in number, evenly distributed in a circle, and their contact with the module string 20 is a line contact.

[0030] The support frame also includes an upper pressure ring and a lower pressure ring 16; the upper pressure ring is fixedly connected to the upper rotating base plate 4, and the lower pressure ring 16 is fixedly connected to the lower rotating base plate 14.

[0031] The pressure curing mechanism includes a cap assembly 1; the cap assembly 1 is assembled on the upper pressure ring by a pin and a clamping claw 101; the pressure ring 103 of the cap assembly 1 adopts a ball joint connection structure, which is configured to transmit only the axial pressure to the module string 20 without rotational friction when the screw 102 is rotated and applied downward.

[0032] To better position the module, this embodiment of the application also includes an inner membrane 17; the inner membrane 17 is placed on the lower pressure ring 16, and the inner membrane 17 has a hollow inner cavity that conforms to the shape of the head of the irregular module.

[0033] Furthermore, it also includes a central positioning ring 13; the central positioning ring 13 is fixedly connected to the fixed support rod 12.

[0034] The following section provides a detailed description of the module string-making tooling provided in this application, using one implementation method as an example.

[0035] The tooling may include a pressure cap assembly 1, an upper pressure ring, an upper rotating slider 3, an upper rotating base plate 4, a connecting rod slider 5, a clamping and retracting slider 6, a connecting rod pin 7, a clamping and retracting pin 8, a tension spring 9, a movable support rod 10, a radial clamping rod 11, a fixed support rod 12, a central positioning ring 13, a lower rotating base plate 14, a lower rotating slider 15, a lower pressure ring 16, an inner membrane 17, a support column 18, a circular base plate 19, and a module string 20.

[0036] Its connection relationship: The upper rotating base plate 4, the lower rotating base plate 14, and the fixed support rod 12 are fixedly connected as a whole. The upper pressure ring is fixedly connected to the upper rotating base plate 4, the lower pressure ring 16 is fixedly connected to the lower rotating base plate 14, and the middle positioning ring 13 is fixedly connected to the fixed support rod 12. The upper rotating slider 3 and the lower rotating slider 15 are slidably fitted onto the upper and lower rotating base plates 14, respectively, and are fixedly connected to the movable support rod 10 as a whole. The upper and lower ends of the radial clamping rod 11 are fixedly connected to the clamping and shrinking slider 6. The clamping and shrinking slider 6 is connected to the connecting rod slider 5 through the clamping and shrinking pin 8. The connecting rod slider 5 is connected to the upper rotating slider 3 and the lower rotating slider 15 through the connecting rod pin 7. The connecting rod pins 7 at both ends are connected to the upper rotating base plate 4 and the lower rotating base plate 14 through the tension spring 9. The circular bottom plate 19 is fixedly connected to the support column 18, and the support column 18 is fixedly connected to the lower pressure ring 16. The inner membrane 17 is placed on the lower pressure ring 16. The pressure cap assembly 1 is assembled to the upper pressure ring through pins and clamping claws 101.

[0037] Depend on Figure 1 , Figure 2It can be seen that the six fixed support rods 12 are evenly distributed in a circle and are fixedly connected to the upper rotating base plate and the lower rotating base plate to form a fixed cage; the three movable support rods 10 are evenly distributed in a circle, pass through the waist holes of the upper rotating base plate and the lower rotating base plate 14 and are fixedly connected to the upper rotating slider and the lower rotating slider respectively. The upper rotating slider and the lower rotating slider are slidably fitted on the upper rotating base plate and the lower rotating base plate to form a movable cage that can rotate around the overall center; the three radial clamping rods 11 are evenly distributed in a circle and are fixedly connected to the clamping and shrinking slider 6 at both ends. The clamping and shrinking slider 6 is movably connected to the connecting rod slider 5 through the clamping and shrinking pin 8. The connecting rod slider 5 is movably connected to the upper rotating slider and the lower rotating slider respectively through the connecting rod pin 7. The connecting rod pin 7 passes through the waist holes of the upper rotating base plate and the lower rotating base plate respectively, and is finally connected to the upper rotating base plate and the lower rotating base plate through the tension spring 9 to form a movable cage that can expand and contract radially.

[0038] like Figure 2 , Figure 3 , Figure 4 , Figure 5 The cage formed by the movable support rod 10 and the cage formed by the radial clamping rod 11 are connected by a tension spring 9 to form a synchronously operating movable cage. When the cage formed by the movable support rod 10 is rotated clockwise by an external force, the cage formed by the radial clamping rod 11 is simultaneously opened counter-clockwise. When the external force is removed, under the tension of the tension spring 9, the cage formed by the movable support rod 10 rotates counter-clockwise, simultaneously clamping the cage formed by the radial clamping rod 11 towards the center. This synchronous clamping ensures the coaxiality between each module.

[0039] The string-making fixture is horizontally positioned via a circular base plate 19. To accommodate the placement of the irregularly shaped head module, the inner membrane 17 uses a hollow cavity with a contoured structure to fit the head of the irregularly shaped module, ensuring the module is level. Then, by switching the cage state, the remaining modules are bonded sequentially. During this process, the bonding status of the modules can be observed and adjusted promptly through the gaps between the rods. Finally, the cage is tightened, and the radial clamping rod 11 makes line contact with the circumferential surface of the module string, ensuring the coaxiality of the module string. After bonding, the module string needs to be pressurized and cured using a pressure cap assembly 1, which is assembled to the upper pressure ring via pins and clamping claws 101. Force is applied downwards by rotating the tightening screw 102. A spherical structure is used to transmit and maintain the force to the module string without moving the pressure ring 103, preventing the pressure ring 103 from rotating and rubbing against the module.

[0040] This embodiment applies to the pre-processing steps of bonding multiple cylindrical and irregularly shaped damaged modules together in a string, including: like Figure 2As shown, the entire fixture is horizontally placed on the worktable via the circular base plate 19. At this time, under the tension of the tension spring 9, the upper rotating slider 3 and the lower rotating slider 15 are in a naturally drooping state, driving the connecting rod slider 5 and the clamping and retracting slider 6, so that the three radial clamping rods 11 are in a state of inward tightening. The operator manually moves the movable support rod 10 counterclockwise to ensure that the movable cage is in the maximum opening position, leaving sufficient space for the module to be inserted.

[0041] The first module with an irregularly shaped head is selected as the reference. This module is placed inside the fixture, with its bottom resting in the inner membrane 17 on the lower pressure ring 16. Since the inner membrane 17 has a hollow cavity that perfectly fits the head of the irregularly shaped module, it can effectively limit the radial displacement of the module and ensure that the module is in a vertical and centered position.

[0042] The operator sequentially inserts the remaining cylindrical modules into the fixture. When placing each module, the operator visually inspects the gap between the outer circle of the module and the rods using the gap formed between the three fixed support rods 12 and the three radial clamping rods 11.

[0043] If the module is found to be tilted, the position of the module can be gently corrected by finely adjusting the tightness of the radial clamping rod 11 and utilizing the line contact characteristics of the rod.

[0044] Apply adhesive to the contact surfaces of the modules and use the three-point centering principle of the tooling to ensure that the central axis of each new module is consistent with the reference module.

[0045] After all modules are stacked to form a module string, the operator manually rotates the movable support rod 10 clockwise to form the movable cage. For example... Figure 6 As shown, the rotational motion is transmitted through the connecting rod pin 7 and the clamping and retracting pin 8, which forces the three radial clamping rods 11 to move radially toward the center in sync until they are in close contact with the outer circumference of the module string.

[0046] At this time, the radial clamping rod 11 applies a uniform circumferential clamping force to the module string 20, forcibly eliminating the cumulative error between modules and ensuring the coaxiality of the entire string.

[0047] like Figure 7 As shown, the cap assembly 1 is assembled onto the upper pressure ring via a pin and a locking claw 101. The operator rotates the screw at the top of the cap assembly 1, and the screw moves downward to push the pressure ring 103.

[0048] Because the pressure ring 103 and the screw adopt a ball joint connection structure, when the screw rotates and presses down, the pressure ring 103 only transmits axial pressure downward and does not rotate with the screw. This avoids frictional rotation between the pressure ring 103 and the top of the module string 20, preventing module misalignment or surface scratches.

[0049] Keep the cap assembly 1 locked and allow it to stand for a period of time until the adhesive is completely cured. After curing, loosen and remove the cap assembly 1, and turn the movable support rod 10 counterclockwise. The radial clamping rod 11 will automatically retract and release under the action of the tension spring 9. At this time, the operator can directly lift the formed module string 20 vertically upward. Since the rod and the module are in line contact and the surface is smooth, the demolding process is smooth and without jamming.

[0050] In summary, the modular stringing fixture provided in this application achieves circumferential synchronous centering and clamping of the modular string through a mechanism in which the rotation of the movable cage drives the radial clamping rod to move synchronously towards the center. Compared with the random errors during traditional manual single-module loading, this fixture utilizes the rigidity and synchronicity of the mechanical structure to forcibly correct the module position, controlling the coaxiality between modules within a very small tolerance range. This effectively solves the problem of difficulty in observing and adjusting coaxiality in a confined space, and significantly improves the overall assembly quality characteristics of the projectile damage unit.

[0051] This tooling allows multiple modules to be pre-bonded together, simplifying the subsequent shell filling process from the traditional multiple fillings and multiple pressing and curing to a single filling and single pressure curing. This change in process mode eliminates the time wasted on repeatedly disassembling and assembling tooling and waiting for curing, significantly shortening the production cycle, and is especially suitable for batch assembly operations of multi-module series structures.

[0052] The design employs a three-bar circular structure, eliminating the blind spots inherent in closed molds. The gaps between the bars provide operators with a good viewing angle, facilitating real-time monitoring of the adhesive layer status and module alignment during bonding, and allowing for immediate fine-tuning. Simultaneously, the radial clamping bars utilize line contact with the module surface, resulting in less friction compared to surface contact. Furthermore, the bars automatically reposition themselves when released, allowing for easy removal of the cured module string and preventing demolding damage.

[0053] The pressure cap assembly employs a ball joint design, converting rotational motion into pure axial linear motion. This design completely eliminates the tangential friction that may occur during the tightening process of traditional rigid pressure heads, preventing relative rotation or surface wear of the modules during pressure application, and ensuring the stability of the pressure curing process and the structural integrity of the module string.

[0054] By configuring an inner membrane with a contoured cavity, the tooling can adapt to irregularly shaped modules with non-standard heads. The inner membrane provides precise positioning and horizontal support for the module head, ensuring accurate baseline positioning of the first module, thereby guaranteeing the verticality and straightness of the entire string of modules and expanding the applicability of the tooling.
