Description

Technical Field

[0001] This utility model relates to the field of radar radome technology, and in particular to a spherical flange edge scribing device for a truncated spherical radome unit. Background Technology

[0002] The radome serves to protect the radar antenna, requiring excellent electromagnetic wave penetration performance and ensuring normal operation of the radar antenna under various conditions and in all weather environments. Fiberglass radomes are typically used in specialized applications. Due to the insulation, corrosion resistance, and high strength of fiberglass products, they are often large in structure and size, and irregular in shape, making their manufacturing process quite challenging.

[0003] like Figure 1 As shown, the fiberglass truncated spherical radome 1, due to its large area, presents numerous inconveniences in manufacturing, transportation, and installation when integrally molded. Therefore, it is generally disassembled into multiple unit components 11 using a modular approach. Traditional unit component scribing tools lack stable positioning and adjustment methods, failing to draw effective straight lines at the junction of the high and low edges of the spherical flange edge 12 of unit component 11. This results in scribing lines at the corners of unit components frequently deviating significantly from the unit component boundaries, leading to excessively large dimensional deviations in the unit components. Consequently, after assembling the unit components, large gaps may appear at the corners, posing safety hazards to the overall radome's sealing and strength, thus affecting the normal and safe operation of the radar antenna.

[0004] The high and low boundary dimensions of each different unit component on the same truncated spherical radome are fixed. Therefore, each unit component is manufactured individually and then assembled into a whole. This necessitates a more rational scribing method to ensure the machining accuracy and efficiency of scribing at the corners of each unit component, thereby obtaining qualified unit components. This ensures that the gaps between each unit component after assembly are more reasonable, the connection strength is better, and the radar antenna inside the radome is used more safely. However, the scribing method used in actual production mainly relies on manual labor or simple fixtures for marking, which presents the following technical problems:

[0005] 1. Unstable positioning: Existing scribing tools usually lack a reliable positioning mechanism, which makes the scribing position easy to deviate and affects the machining accuracy.

[0006] 2. Inability to adapt to changes in flange height: There are height differences on the flange edges of the unit components. Traditional scribing methods cannot guarantee accurate scribing of the curved transition area, resulting in large gaps between the unit components after assembly, which affects the sealing and mechanical performance of the radome.

[0007] 3. Low efficiency: Manual scribing or traditional fixtures require multiple adjustments and measurements, resulting in low processing efficiency. Furthermore, the scribing results are greatly affected by the operator's experience, making it difficult to guarantee consistency. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide a spherical flange edge scribing device for truncated spherical radome unit components. This device overcomes the defects of traditional truncated spherical radome unit component scribing, ensures the accuracy of unit component boundary scribing, improves scribing efficiency and unit component assembly accuracy, and has a simple structure and is easy to operate.

[0009] To solve the above-mentioned technical problems, the present invention provides a spherical flange edge conformal marking device for a truncated spherical radome unit, comprising a guide rail, a long base plate, a connecting block, a positioning rod, an adjustable rod, a clamping frame, and a drawing pen. The connecting block is located at one end of the long base plate, and one end of the guide rail is located on the top surface of the connecting block. The guide rail and the long base plate are arranged in a straight line. The long base plate is provided with through holes and long grooves at intervals. The positioning rod and the adjustable rod are respectively located in the through holes and long grooves of the long base plate, and the adjustable rod can slide along the long groove. The clamping frame is located on the guide rail and slides along the guide rail. The drawing pen is floating on the clamping frame by a spring.

[0010] Furthermore, the upper and lower end faces of the clamping frame are provided with through holes at intervals, the paintbrush is inserted into the through holes of the upper and lower end faces of the clamping frame, a pressure plate is provided in the middle of the paintbrush, and the spring is sleeved on the outer ring of the paintbrush and located between the upper end face of the clamping frame and the pressure plate.

[0011] Furthermore, the vertical floating distance of the brush is 0-10mm.

[0012] Furthermore, the length of the long groove in the elongated bottom plate is 45mm.

[0013] Furthermore, the paintbrush can be electrically adjusted.

[0014] Because this utility model's spherical flange edge conformal scribing device for truncated spherical radome unit adopts the above-mentioned technical solution, namely, the connecting block of this device is located at one end of the long base plate, and the guide rail is located at one end of the top surface of the connecting block. The guide rail and the long base plate are arranged in a straight line. The long base plate has through holes and long slots at intervals. The positioning rod and the adjustable rod are respectively located in the through holes and long slots of the long base plate, and the adjustable rod can slide along the long slot. The clamping frame is located on the guide rail and slides along the guide rail. The scribing pen is floating on the clamping frame by a spring. This device overcomes the defects of traditional truncated spherical radome unit scribing, ensures the accuracy of unit boundary scribing, improves scribing efficiency and unit assembly accuracy, and has a simple structure and is easy to operate.

[0017] Figure 2This is a schematic diagram of the spherical flange edge conformal scribing device for the truncated spherical radome unit of this utility model. Detailed Implementation

[0018] Example 1

[0019] Implementation, for example Figure 2 As shown, the spherical flange edge conformal marking device of the truncated spherical radome unit of this utility model includes a guide rail 2, a long strip base plate 3, a connecting block 4, a positioning rod 5, an adjustable rod 6, a clamping frame 7, and a drawing pen 8. The connecting block 4 is located at one end of the long strip base plate 3, and one end of the guide rail 2 is located on the top surface of the connecting block 4. The guide rail 2 and the long strip base plate 3 are arranged in a straight line. The long strip base plate 3 is provided with through holes 31 and long grooves 32 at intervals. The positioning rod 5 and the adjustable rod 6 are respectively located in the through holes 31 and long grooves 32 of the long strip base plate 3, and the adjustable rod 6 can slide along the long groove 31. The clamping frame 7 is located on the guide rail 2 and slides along the guide rail 2. The drawing pen 8 is floating on the clamping frame 7 by a spring 9.

[0020] Preferably, the clamping frame 7 has through holes spaced apart on its upper and lower end faces. The pen 8 is inserted into the through holes on the upper and lower end faces of the clamping frame 7. A pressure plate 81 is provided in the middle of the pen 8. The spring 9 is sleeved on the outer ring of the pen 8 and is located between the upper end face of the clamping frame 7 and the pressure plate 81. When the pen draws a line following the shape, the pen is always pressed against the flange edge of the unit component by the push of the spring. When the pen is pushed upward, the pressure plate compresses the spring, causing the pen to float up, thereby enabling the pen to draw a line following the shape.

[0021] Preferably, the vertical floating distance of the pen 8 is 0-10mm. This is to adapt to the need for drawing lines at the corners of unit components of different specifications and to meet the vertical floating distance of the pen for drawing lines according to their shape.

[0022] Preferably, the length of the long groove 32 of the elongated base plate 3 is 45mm. The length of the long groove ensures that the adjustable rod can always find the existing screw hole on the flange side of the unit component, and the elongated base plate can be reliably fixed to the flange side of the unit component in conjunction with the positioning rod.

[0023] During the scribing operation on the spherical flange edge of the unit component, the elongated base plate 3 is placed against the flange edge 12 of the unit component 11. The elongated base plate 3 is fixed to any two pre-existing holes on the flange edge 12 of the unit component 11 using the positioning rod 5 and the adjustable rod 6. The position of the adjustable rod 6 within the long groove 32 of the elongated base plate 3 is adjusted according to the distance between the two holes. At this point, the position of the pen 8 is the scribing position. Simultaneously, the scribing action is achieved by the pen sliding back and forth on the guide rail 2 via the clamping frame 7, resulting in the scribing line 13 at the corner of the flange edge 12 of the unit component 11. During this process, due to the height difference of the scribing line 13 at the corner, this device can accurately scribing the line through the floating setting of the pen, thereby improving the accuracy of unit component manufacturing and ensuring the quality of assembly of adjacent unit components.

[0024] This device facilitates the processing, cutting, and positioning of the junction between the high and low edges of fiberglass dome products, optimizes and simplifies the processing technology, saves production costs, improves the processing accuracy and quality of products, and achieves universality for conformal scribing and positioning on the flange edge of different specifications of truncated dome antenna unit components.
