Description

Technical Field

[0001] This invention relates to the field of radar dome manufacturing, specifically to a method for precisely manufacturing rubber sealing tape connection holes for composite domes. Background Technology

[0002] After drilling holes in the composite cover using a drill jig, the rubber sealing strip is too soft to be drilled with a drill bit. Usually, a blade is used to cut the rubber sealing strip along the edge of the hole in the composite cover. This method is very easy to damage the composite cover and the hole position accuracy is low, making it unsuitable for composite covers with high hole position accuracy for the sealing strip connection holes. Summary of the Invention

[0003] The present invention aims to solve the problem of quickly and accurately producing connection holes for the composite cover rubber sealing strip by designing a composite cover drilling device that can simultaneously drill holes in the composite cover and the composite cover rubber sealing strip without damaging the composite cover.

[0004] This invention proposes a method for precisely manufacturing connecting holes for rubber sealing strips used in composite covers. The method incorporates a composite cover drilling device designed based on the shape of the composite cover and the drilling positions. This device has a fixed platform on a support leg, and the platform has a limiting drilling die and several quick clamping devices. The limiting drilling die has a drill hole at the drilling position, in which a drill sleeve is installed. The platform has a through hole at the drill hole position. The device also includes a pressure plate and a punch. When drilling, first position the composite cover rubber sealing strip on the upper end of the limiting drilling mold; then place the pressure plate on the upper end of the composite cover rubber sealing strip and press the pressure plate with a quick clamping device; control the punch to quickly pass through the drill bushing at the lower end of the table to cut out the connecting hole of the composite cover rubber sealing strip.

[0005] Advantageously, the outer diameter of the punch matches the inner diameter of the drill sleeve.

[0006] Advantageously, the boundary positioning of the composite cover rubber sealing strip is achieved by the shape of the limiting punching mold.

[0007] Advantageously, the number of legs is multiple, which ensures the drilling operation space.

[0008] Advantageously, the drill bushing extends through the drill jig hole and the table through hole.

[0009] Advantageously, the number of the quick clamps is multiple.

[0010] Advantageously, the quick clamping device is distributed along the limiting punching die.

[0011] Advantageously, the composite cover is also perforated by the composite cover perforation device before the rubber sealing strip connection holes are processed.

[0012] Beneficial effects: This invention ensures the consistency between the connection hole of the rubber sealing strip in the composite cover and the hole position of the composite cover, increases the efficiency of accurately making the connection hole of the rubber sealing strip, and reduces the probability of damaging the composite cover when making the connection hole of the rubber sealing strip, thereby generating good economic benefits.

[0014] 1-Support leg, 2-Limiting punching die, 3-Tabletop, 4-Quick clamping device, 5-Pressure plate, 6-Composite cover, 7-Composite cover rubber sealing strip, 8-Drill bushing, 9-Punch Detailed Implementation See Figure 1 The composite cover drilling device mainly includes: support leg 1, limiting drilling mold 2, table 3, quick clamping device 4, pressure plate 5, and drill sleeve 8. The table 3 is fixed to the support leg 1, which raises the table 3 to ensure sufficient space for drilling operations. The limiting drilling mold 2 is fixed to the table 3 and has a through-hole drill hole on it, into which the drill sleeve 8 is installed, with its lower end extending through the table 3. The composite cover 6 is placed on the limiting drilling mold 2 and accurately positioned by its boundary. After the pressure plate 5 is placed on the upper part of the composite cover 6, the quick clamping device 4 on the table 3 presses down on the pressure plate 5, and the drill sleeve 8 drills a hole in the composite cover 6 from the lower side of the limiting drilling mold 2.

[0015] When punching holes in the composite cover rubber sealing strip 7 using the aforementioned composite cover punching device, the composite cover rubber sealing strip 7 is first placed on the limiting punching mold 2, and the boundary positioning of the composite cover rubber sealing strip 7 is achieved by the limiting punching mold 2.

[0016] Then, place the pressure plate 5 on the upper end of the rubber sealing strip 7 of the composite cover, and press the pressure plate 5 down with the quick clamp 4.

[0017] The outer diameter of the punch 9 is the same as that of the drill sleeve 8. The head of the punch 9 quickly passes through the drill sleeve 8 upwards to directly cut out the connecting hole of the composite cover rubber sealing strip 7, ensuring the consistency of the hole positions of the composite cover 6 and the composite cover rubber sealing strip 7, so as to meet the requirement of quickly and accurately producing the connecting hole of the composite cover rubber sealing strip.

[0018] Without damaging the composite cover, the success rate of accurately producing the rubber sealing strip connection hole of the composite cover is improved, resulting in better economic benefits.
