Description

[Technical Field]

[0001] This utility model relates to the field of radome manufacturing technology, specifically to a stretching mechanism for radome processing and forming. [Background Technology]

[0002] Antenna radomes 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 the continuous production of radomes of unlimited length. When producing tractor radomes, a stretching mechanism is typically used to clamp the formed radome, slowly pulling it before cutting it to the required length.

[0003] During the production of radomes, there are radomes of different sizes. If different models of molds are used to produce different models of radomes, the stretching mechanism must also be changed accordingly, which will affect production efficiency.

[0004] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to provide a stretching mechanism for radome processing and forming. By setting the fixed clamping plate in the clamping assembly to be adjustable, the distance between the fixed clamping plate and the moving clamping plate can be adjusted to adapt to radomes of different sizes, thus solving the problem that the existing stretching mechanism cannot adapt to radomes of different sizes.

[0006] To solve the above-mentioned technical problems, this utility model proposes a stretching mechanism for radome processing and forming, including a frame and a clamping assembly disposed on the frame and slidably cooperating with the frame for clamping the radome, and a driving assembly disposed on the frame for driving the clamping assembly to reciprocate along the frame.

[0007] The clamping assembly includes a base that slides with the frame, a pair of support seats spaced apart on the base, a movable clamping plate located between the lower parts of the support seats, and a fixed clamping plate located between the upper parts of the support seats and whose distance from the movable clamping plate can be adjusted longitudinally to accommodate radomes of different sizes. The clamping assembly also includes a first driving member located on the base to drive the movable clamping plate to move.

[0008] As described above, a stretching mechanism for forming an antenna radome has several threaded rods on a fixed clamping plate, a fixed plate on the top of a support base, the threaded rods being movably connected to the fixed plate, and adjusting nuts at both ends of the fixed plate being threadedly connected to the threaded rods to fix the threaded rods to the fixed plate.

[0009] As described above, a stretching mechanism for forming an antenna radome has a support base with several longitudinally arranged strip holes, and bolts for threaded engagement with a fixed clamping plate are provided at the strip holes.

[0010] As described above, a stretching mechanism for forming an antenna radome has several guide rods that slide with the base on the moving clamp plate. The first driving component is a hydraulic cylinder, which is located on the base and its piston rod is connected to the moving clamp plate.

[0011] As described above, a stretching mechanism for forming an antenna radome includes a drive assembly comprising a second drive member mounted on a frame and a connecting plate mounted at the bottom of a base. The second drive member is a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the connecting plate.

[0012] As described above, a stretching mechanism for forming an antenna radome has a "convex" shaped cross-section, a base that slides with the top of the frame, a clearance opening for the connecting plate to move on the top of the frame, and a second driving component located at one end of the frame and connected to the connecting plate.

[0013] As described above, in a stretching mechanism for forming an antenna radome, protective pads are provided on the clamping surfaces of the moving clamping plate and the fixed clamping plate.

[0014] As described above, a stretching mechanism for forming an antenna radome is provided outside the frame, which is surrounded by a clamping assembly and a drive assembly, and the outer frame is connected to the frame.

[0015] Compared with the prior art, the stretching mechanism for antenna radome processing and forming of this utility model has the following advantages:

[0016] 1. In this application, by setting the fixed clamping plate to be adjustable, the distance between the fixed clamping plate and the moving clamping plate can be adjusted to accommodate antenna covers of different sizes, significantly improving the versatility of the equipment, reducing the time cost of changing tooling, and thus improving production efficiency.

[0017] 2. In this application, the threaded rod can be fixed on the fixed plate by rotating the adjusting nut, which in turn can fix the movable clamp plate. Furthermore, by rotating the adjusting nut, the size of the antenna cover can be steplessly adjusted to an appropriate position, making it convenient for users to debug. [Attached Image Description]

Detailed Implementation Methods

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown, the present invention includes a stretching mechanism for forming an antenna radome, including a frame 1 and a clamping assembly 2 disposed on the frame 1 and slidably engaged with the frame 1 for clamping the antenna radome, and also includes a driving assembly 3 disposed on the frame 1 for driving the clamping assembly 2 to reciprocate along the frame 1.

[0031] The clamping assembly 2 includes a base 20 that slides with the frame 1, a pair of support seats 21 spaced apart on the base 20, a movable clamping plate 22 located between the lower parts of the support seats 21, and a fixed clamping plate 23 located between the upper parts of the support seats 21 and whose distance from the movable clamping plate 22 can be adjusted longitudinally to accommodate radomes of different sizes. The clamping assembly 2 also includes a first driving member 24 located on the base 20 to drive the movable clamping plate 22 to move.

[0032] Antenna radomes 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 the continuous production of radomes of unlimited length. When producing tractor radomes, a stretching mechanism is typically used to clamp the formed radome, slowly pulling it before cutting it to the required length.

[0033] In this application, by making the fixed clamping plate 23 adjustable, the distance between the fixed clamping plate 23 and the moving clamping plate 22 can be adjusted to accommodate radomes of different sizes, thereby significantly improving the versatility of the equipment and reducing the time cost of changing tooling.

[0034] like Figures 2 to 3 As shown, as a further embodiment, the fixed clamping plate 23 is provided with several threaded rods 25, and a fixing plate 26 is provided on the top of the support base 21. The threaded rods 25 are movably connected to the fixing plate 26, and the upper and lower ends of the fixing plate 26 are provided with adjusting nuts 27 that are threadedly connected to the threaded rods 25, thereby fixing the threaded rods 25 to the fixing plate 26. The support base 21 is provided with several longitudinal slots 28, and bolts 29 for threaded engagement with the fixed clamping plate 23 are provided at the slots 28. In this embodiment, by rotating the adjusting nuts 27, the threaded rods 25 can be fixed to the fixing plate 26, thereby fixing the movable clamping plate 22. Furthermore, by rotating the adjusting nuts 27, the size of the radome can be adjusted to an appropriate position, facilitating user adjustment. In addition, to make the fixed clamp 23 more stable during use, a strip hole 28 is provided on the support base 21. After adjusting the position of the fixed clamp 23, the fixed clamp 23 is further fixed to the support base 21 by passing the bolt 29 through the strip hole 28.

[0035] like Figures 2 to 3 As shown, as a further embodiment, the movable clamping plate 22 is provided with a plurality of guide rods 220 that slide in cooperation with the base 20. The first driving member 24 is a hydraulic cylinder, which is located on the base 20 and its piston rod is connected to the movable clamping plate 22. In this embodiment, the movable clamping plate 22 can be guided by the cooperation of the guide rods 220 and the base 20, so that the movable clamping plate 22 can be more stable and smooth during the clamping process.

[0036] like Figures 2 to 4As shown, as a further embodiment, the drive assembly 3 includes a second drive member 30 mounted on the frame 1 and a connecting plate 31 located at the bottom of the base 20. The second drive member 30 is a hydraulic cylinder, and the piston rod of the hydraulic cylinder is connected to the connecting plate 31. The frame 1 has a convex cross-section. The base 20 is slidably fitted to the top of the frame 1. An clearance opening 32 for the connecting plate 31 to move is formed on the top of the frame 1. The second drive member 30 is located at one end of the frame 1 and is connected to the connecting plate 31. In this embodiment, the frame 1 has a convex cross-section and is hollow, allowing the piston rod of the second drive member 30 to extend into it. The second drive member 30 then drives the base 20 to move by driving the connecting plate 31. It should also be noted that a guide rail can be provided on the frame 1, and a slider can be provided at the bottom of the base 20. The slider slides against the guide rail, thereby achieving a sliding fit between the clamping assembly 2 and the frame 1. It should be noted that the sliding engagement of the guide rail and slider is a conventional technique in this field; therefore, the guide rail and slider are not indicated in this application. Furthermore, in this application, the first drive member 24 and the second drive member 30 can also be replaced by a cylinder or an electric actuator.

[0037] like Figure 2 As shown, as a further embodiment, a protective pad 4 is provided on the clamping surfaces of the movable clamping plate 22 and the fixed clamping plate 23. In this embodiment, the protective pad 4 is made of polytetrafluoroethylene, 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. In addition, the upper shell of the protective pad 4 is provided with anti-slip texture, which is not shown in this application, and can prevent the movable clamping plate 22 and the fixed clamping plate 23 from sliding when pulling the radome.

[0038] like Figure 1 As shown, as a further embodiment, the frame 1 is further provided with an outer frame 10 surrounding the clamping component 2 and the driving component 3, and the outer frame 10 is connected to the frame 1. By setting the outer frame 10, the clamping component 2 and the driving component 3 can be surrounded, preventing foreign objects from falling into it and affecting the operation. Furthermore, by connecting the frame 1 and the outer frame 10, the entire stretching mechanism can be made more stable.
