Description

An internal support fixture for radome forming Technical Field

[0001] This utility model relates to the field of radome manufacturing technology, specifically to an internal support fixture for radome forming, used to prevent radome deformation during traction. Background Technology

[0002] Antenna radomes have advantages such as corrosion resistance, aging resistance, long lifespan, strong electrical insulation and wave transmission, which can play a good protective role for antennas and maximize their performance. Antenna radomes are suitable for various complex environments and are widely used in aerospace, communications, meteorology and other fields.

[0003] Antenna radomes are generally produced using a pultrusion molding process. This involves pressing and curing continuous untwisted rovings, felt, tape, or cloth, etc., impregnated with adhesive, through a mold under traction force to create fiberglass radomes of unlimited length. When producing tractor radomes, clamping equipment is typically used to hold the formed radome, slowly pulling it, and then cutting it to the required length.

[0004] When clamping the radome, since it is newly formed and not yet fully hardened, it has not yet reached its normal supporting strength. If the clamping force is too large, the radome is prone to deformation and cracking. If the clamping force is too small, the clamping equipment is prone to sliding with the radome. If the radome is allowed to fully harden, the curing time will be too long, resulting in low production efficiency.

[0005] In view of the above-mentioned technical problems, this utility model is proposed in this study. Summary of the Invention [Summary of the Utility Model]

[0006] The technical problem to be solved by this utility model is to provide an internal support fixture for radome processing. By setting an internal support fixture in the radome, a stable clamping structure is formed by the upper support plate and the lower support plate. During the traction process, the external force is evenly distributed, avoiding problems such as deformation and cracking of the radome due to excessive local stress, thereby improving the yield and production efficiency.

[0007] To solve the above-mentioned technical problems, this utility model proposes an internal support clamp for radome forming. The internal support clamp is located in the formed radome and is used to clamp the radome to prevent deformation during traction. The internal support clamp includes an upper support plate and a lower support plate arranged parallel to each other at intervals, and a middle connecting assembly disposed between the upper and lower support plates to connect the two. The upper support plate and the lower support plate are detachably connected to the middle connecting assembly. The internal support clamp also includes a forming device for connecting the radome and an elastic reset member for connecting the middle connecting assembly to reset the internal support clamp to its initial position in the radome.

[0008] As described above, an internal support fixture for radome forming includes a central connecting assembly comprising a pair of spaced-apart fixed plates and a pair of parallel connecting plates between the two fixed plates. The left and right ends of the connecting plates are fixedly connected to the corresponding fixed plates. The elastic reset member is connected to one of the fixed plates. The bottom of the upper support plate is detachably connected to the connecting plate, and the lower support plate is detachably connected to the connecting plate.

[0009] As described above, a built-in support fixture for radome processing and forming has mounting holes formed on both the upper and lower support plates that correspond to the connection points of the connecting plate. The upper and lower support plates are connected to the connecting plate by screws being inserted into the mounting holes.

[0010] As described above, an internal support fixture for radome forming has a pair of spaced-apart limiting plates formed on both the upper and lower support plates, with a connecting groove formed between the limiting plates. The two connecting plates are embedded in the connecting groove, and the limiting plates are also provided with fixing members for fixing them to the connecting plates.

[0011] As described above, an internal support fixture for radome forming has a fixing component consisting of bolts and nuts. The bolts pass through the two limiting plates and the two connecting plates and then cooperate with the nuts to lock the limiting plates onto the connecting plates.

[0012] As described above, a built-in support fixture for forming an antenna radome has a longitudinally formed strip hole on the connecting groove for bolts to pass through.

[0013] The built-in support fixture for radome forming as described above is characterized in that the outer surfaces of both connecting plates are formed with limiting grooves for the insertion of limiting plates.

[0014] As described above, a built-in support fixture for radome processing and forming includes an elastic reset component comprising a spring and a connecting tube. One end of the spring is connected to the connecting tube, and the other end is connected to a fixing plate. The other end of the connecting tube is connected to the radome forming equipment.

[0015] As described above, the built-in support fixture for radome processing and forming is provided, wherein the upper support plate and the lower support plate are made of plastic.

[0016] As described above, in a built-in support fixture for radome forming, both the upper support plate and the lower support plate have anti-slip textures formed on their surfaces.

[0017] Compared with the prior art, the built-in support fixture for radome processing and forming of this utility model has the following advantages:

[0018] 1. This application sets up an internal support clamp placed in the radome, and forms a stable clamping structure through the upper support plate and the lower support plate. During the traction process, the external force is evenly distributed, avoiding problems such as deformation and cracking of the radome due to excessive local stress, which can improve the yield and production efficiency.

[0019] 2. This application places the built-in support fixture in the radome, eliminating the need for additional external fixing devices for positioning, simplifying the processing flow, reducing the need for operating space, and improving processing efficiency.

[0020] 3. The upper and lower support plates are detachably connected to the middle connecting assembly, which facilitates the adjustment of the support spacing according to the size of the radome, adapts to the processing requirements of different product specifications, and simplifies the assembly and maintenance of the fixture.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] As shown in Figures 1-8, this utility model includes a built-in support clamp for forming an radome. The built-in support clamp is located in the formed radome and is used to clamp the radome to prevent deformation during traction. The built-in support clamp includes an upper support plate 1 and a lower support plate 2 arranged parallel to each other at intervals, and a middle connecting component 3 disposed between the upper support plate 1 and the lower support plate 2 to connect the two. The upper support plate 1 and the lower support plate 2 are detachably connected to the middle connecting component 3. The built-in support clamp also includes a forming device for connecting the radome and an elastic reset member 4 for connecting the middle connecting component 3 to reset the built-in support clamp to its initial position in the radome.

[0035] Antennae are generally produced using a pultrusion molding process. Reinforcing materials such as continuous untwisted rovings, felt, tape, or cloth impregnated with adhesive are extruded through a mold under traction force, then cured, allowing for continuous production of antennae of unlimited length. When traction antennae production, the formed antennae is typically held in place by a clamping device, slowly pulled, and then cut to the required length. However, since the antennae is newly formed and not yet fully hardened, it has not reached its normal supporting strength. Excessive clamping force can easily cause deformation and breakage, while insufficient force can cause the clamping device to slip. Waiting for the antennae to fully cure requires a long curing time, resulting in low production efficiency. Therefore, this application incorporates an internal support clamp within the antennae. The upper support plate 1 and lower support plate 2 form a stable clamping structure, evenly distributing external force during traction and preventing deformation and breakage due to excessive localized stress. This improves yield and production efficiency.

[0036] Furthermore, this application places the built-in support fixture within the radome, eliminating the need for additional external fixing devices for positioning, simplifying the processing flow, reducing the need for operating space, and improving processing efficiency. Moreover, the upper support plate 1 and lower support plate 2 are detachably connected to the central connecting assembly 3, facilitating adjustments to the support spacing according to the radome size, adapting to the processing requirements of products with different specifications, and simplifying the assembly and maintenance of the fixture.

[0037] The middle connecting assembly 3 includes a pair of spaced-apart fixed plates 30 and a pair of parallel connecting plates 31 between the two fixed plates 30. The left and right ends of the connecting plates 31 are fixedly connected to the corresponding fixed plates 30. The elastic reset member 4 is connected to one of the fixed plates 30. The bottom of the upper support plate 1 is detachably connected to the connecting plate 31. The lower support plate 2 is detachably connected to the connecting plate 31.

[0038] The elastic reset component 4 includes a spring 40 and a connecting tube 41. One end of the spring 40 is connected to the connecting tube 41, and the other end is connected to the fixing plate 30. The other end of the connecting tube 41 is connected to the radome forming equipment. After the clamping equipment clamps and stretches the formed radome a certain distance, the clamping equipment releases the radome, and the built-in support clamp returns to its initial position under the action of the spring 40. After the clamping equipment returns to its initial position, it continues to clamp and stretch the radome, and this process is repeated.

[0039] In this application, the central connecting component 3 adopts a rigid structure, which can improve the support performance and prevent deformation. The two connecting plates 31 are fixedly connected to the two fixed plates 30 to form a rectangular central connecting component 3, which improves the support performance. After traction is completed, the elastic reset component 4 can reset the entire built-in support fixture under the action of elastic force without manual intervention, ensuring repeatability and positioning accuracy and guaranteeing consistency in mass production.

[0040] As a further embodiment, the upper support plate 1 and the lower support plate 2 are made of plastic, and both the upper support plate 1 and the lower support plate 2 have anti-slip textures formed on their surfaces. These anti-slip textures are not shown in this application. In this embodiment, the upper support plate 1 and the lower support plate 2 are made of polytetrafluoroethylene (PTFE), which has high-temperature resistance, can withstand the residual heat left after the radome is formed, and has moderate hardness so as not to scratch the radome. Furthermore, the anti-slip textures prevent the entire internal support clamp from sliding during the traction of the radome.

[0041] As shown in Figure 6, in a preferred embodiment, both the upper support plate 1 and the lower support plate 2 are formed with mounting holes 32 corresponding to the connection points with the connecting plate 31. The upper support plate 1 and the lower support plate 2 are connected to the connecting plate 31 by screws inserted into the mounting holes 32. In this embodiment, by directly creating the mounting holes 32 on the upper support plate 1 and the lower support plate 2, the manufacturing process is simple, reducing manufacturing costs and enabling quick and convenient installation.

[0042] As shown in Figures 1 to 6, in another preferred embodiment, both the upper support plate 1 and the lower support plate 2 are formed with a pair of spaced-apart limiting plates 33, with a connecting groove 34 formed between the limiting plates 33. The two connecting plates 31 are embedded in the connecting groove 34, and the limiting plates 33 are also provided with fixing members 35 for fixing them to the connecting plates 31. Compared with the method of directly drilling holes in the upper support plate 1 and the lower support plate 2 for fixing, although this embodiment adds limiting plates 33 and connects them to the connecting plates 31 through the limiting plates 33, the manufacturing cost is higher. However, the first method, after drilling holes in the upper support plate 1 and the lower support plate 2, is prone to damage to its own structure, resulting in a decrease in support strength. Under long-term use, the drilling points are prone to deformation and damage. Compared with the first method, this embodiment can keep the support surfaces of the first support plate and the second support plate intact, which can increase the service life and reduce the later maintenance costs.

[0043] As shown in Figure 4, as a further embodiment, the fixing member 35 is composed of a bolt 350 and a nut 351. The bolt 350 passes through the two limiting plates 33 and the two connecting plates 31 and then cooperates with the nut 351 to lock the limiting plate 33 onto the connecting plate 31. The connecting groove 34 has a longitudinally formed strip hole 37 for the bolt 350 to pass through. By setting the strip hole 37, the bolt 350 is not subjected to longitudinal force. When clamping the antenna cover, the force on the upper support plate 1 and the lower support plate 2 is directly transmitted to the connecting plate 31.

[0044] As shown in Figure 4, as a further embodiment, both connecting plates 31 have limiting grooves 36 formed on their outer surfaces for the limiting plate 33 to be inserted. The limiting grooves 36 facilitate positioning.
