Description

Technical Field

[0001] This invention relates to the field of radar dome processing equipment technology, and in particular to a radar dome edge cutting dust collection device and dust collection method. Background Technology

[0002] In existing technologies, radomes typically use structural forms such as half-wave wall structures, single-layer thin-wall structures, and sandwich structures. Sandwich structures often use aramid paper honeycomb core layers and PMI foam core layers. PMI foam often requires processing, cutting, and splicing due to limitations in material size and part shape. Composite material radomes, on the other hand, have advantages such as light weight, high strength and rigidity, and good molding processability, leading to their increasingly widespread use in aircraft manufacturing. To ensure that the performance indicators of composite material radomes meet design requirements, different composite material radomes must be assembled into a single unit before being mounted on the aircraft. Composite material radome surfaces are divided into molded surfaces and non-molded surfaces. Molded surfaces are those that adhere to the mold during molding, characterized by high dimensional accuracy and good surface finish. Non-molded surfaces do not adhere to the mold during molding, and... Most of them have a certain margin, resulting in poor dimensional accuracy and surface finish. The assembly surface of some composite material radomes is a non-molded surface. In order to ensure the wall thickness and assembly accuracy, the non-molded surface needs to be ground and fitted. The traditional fitting method is manual fitting. After removing a certain margin, a template is used to check whether the fitting position meets the requirements. However, when performing edge cutting and grinding and other fitting operations on the radome in this way, especially when performing large-scale edge cutting operations, a lot of dust is generated, which leads to dust pollution and affects the processing accuracy of the radome. In the current production process, special personnel are equipped with handheld dust collection equipment to remove the dust generated during the edge cutting process. This requires multiple operators to cooperate during the processing, which reduces work efficiency and wastes labor. Moreover, because the dust collection equipment is large, the workers cannot hold the dust collection equipment for a long time, which affects the processing progress.

[0003] Chinese invention patent application number 201811492085.4 discloses a device and method for rapid replication and grinding of composite material radome surfaces. The device includes a rotating shaft, a surface plate, a positioning pin, a support frame assembly, a grinding head, and a positioning plate; the support frame assembly includes a fixed frame and a moving rod. However, this device for rapid replication and grinding of composite material radome surfaces is structurally complex and cannot vacuum the radome body during the grinding process. It still requires a separate worker to use a handheld vacuum cleaner, resulting in a limited and labor-intensive vacuuming method and poor practicality. Summary of the Invention

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] A radome edge-cutting dust collection device includes a dust collection mechanism, a positioning mechanism, and a clamping mechanism. The dust collection mechanism is arranged on the edge of the radome body, the positioning mechanism is located at the connection between the dust collection mechanism and the radome body, and the clamping mechanism is located on one side of the dust collection mechanism. The dust collection mechanism is configured to correspond to the edge of the radome body through the positioning mechanism and the clamping mechanism. A schematic diagram of the overall structure of the invention is shown below. Figure 1 As shown.

[0031] The dust collection mechanism includes a side dust collection hood 1 and a dust collection bellows 2. The side dust collection hood 1 is disposed on the side of the radome body, with one end open. A mounting groove is provided at the lower part of the open end of the side dust collection hood 1 corresponding to the edge of the radome body. The side dust collection hood 1 is disposed on the side of the radome body through the mounting groove. The dust collection bellows 2 is located at the end of the side dust collection hood 1 away from its open end and is fixedly connected to the side dust collection hood 1. One end of the dust collection bellows 2 communicates with the interior of the side dust collection hood 1, and the end of the dust collection bellows 2 away from the side dust collection hood 1 is connected to an external dust collection device. The dust collection mechanism, through the cooperation of the side dust collection hood 1 and the dust collection corrugated pipe 2, is flexibly configured on the side of the radome body under the action of the positioning mechanism and the clamping mechanism. It removes dust during the grinding and processing of the radome body without the need for manual lifting. The side dust collection hood 1 serves as a cover in the dust collection structure to improve dust collection efficiency and effect. The dust collection corrugated pipe 2 connects to the side dust collection hood 1 and connects the side dust collection hood 1 to external dust collection equipment to form a dust collection structure to remove dust generated during the cutting process of the radome body. A side view of the dust collection mechanism of this invention is shown below. Figure 2 As shown.

[0032] It also includes an inner wall vacuuming assembly, which includes a vacuuming connecting pipe 3 and an inner wall fitting cover 4. The vacuuming connecting pipe 3 is located in the middle of the vacuuming corrugated pipe 2 and is fixedly connected to the vacuuming corrugated pipe 2, communicating with the vacuuming corrugated pipe 2. The inner wall fitting cover 4 is located on the side of the vacuuming connecting pipe 3 and is fixedly connected to the vacuuming connecting pipe 3, communicating with the inside of the vacuuming connecting pipe 3. A filter screen is provided on the inner side of the inner wall fitting cover 4, and the edge of the inner wall fitting cover 4 corresponds to the inner wall contour design of the radar dome body. The dust collection component, in conjunction with the dust collection connecting pipe 3 and the inner wall fitting cover 4, forms a dust removal structure for the inner wall of the radome body to remove dust from the inner wall of the radome body. The dust collection connecting pipe 3 is used to connect with the dust collection corrugated pipe 2, and the inner wall fitting cover 4 is used to remove dust from the inner wall of the radome body. Thus, together with the side dust collection cover 1, a double dust collection structure is formed to perform corresponding dust collection operations on different parts of the radome body. The filter screen is used to filter out large-volume impurities to prevent large impurities from damaging the dust collection mechanism.

[0033] The positioning mechanism includes a positioning mounting plate 5, a positioning mounting bracket 6, a positioning screw 7, and a positioning mounting block 8. The positioning mounting plate 5 is positioned inside the side dust collection hood 1, corresponding to the edge of the radome body. The positioning mounting bracket 6 is positioned on the upper part of the positioning mounting plate 5 near the dust collection bellows 2 and is fixedly connected to the positioning mounting plate 5 by screws. The positioning screw 7 is positioned at the lower part of the positioning mounting bracket 6 and is threadedly connected to the positioning mounting bracket 6. One end of the positioning screw 7 passes through the side dust collection hood 1 and protrudes beyond it. A rotating knob is provided at the end of the positioning screw 7 protruding beyond the side dust collection hood 1. The positioning screw 7 is perpendicular to the positioning mounting plate 5. The positioning mounting block 8 is positioned at the end of the positioning screw 7 near the positioning mounting plate 5 and is fixedly connected to the positioning screw 7. The edge of the radome body is located between the positioning mounting block 8 and the positioning mounting plate 5. The dust collection mechanism is configured on the edge of the radome body through the positioning mechanism. The positioning mechanism is connected to the positioning mounting plate 5 and the positioning mounting bracket 6. The positioning screw 7 and the positioning mounting block 8 cooperate to relative position the side dust suction hood 1 with the edge of the radar dome body, thereby placing the side dust suction hood 1 on the edge of the radar dome body. The positioning mounting plate 5 provides mounting support for the positioning mounting frame 6, which in turn provides mounting support for the positioning screw 7 and connects it to the positioning mounting plate 5. The positioning screw 7 provides mounting support for the positioning mounting block 8 and drives it to move horizontally, thus changing the distance between the positioning mounting block 8 and the positioning mounting plate 5. The positioning mounting block 8, under the action of the positioning screw 7, changes its distance from the positioning mounting plate 5, thereby relative positioning the side dust suction hood 1 with the edge of the radar dome body. The side dust suction hood 1 can be positioned on the edge of the radar dome body by rotating the positioning screw 7. The side dust suction hood 1 can be quickly positioned or unlocked from the radar dome body using the positioning screw 7. A schematic diagram of the positioning mechanism of this invention is shown below. Figure 3 As shown.

[0034] It also includes a weight reduction groove 9, which is located in the middle of the positioning mounting plate 5 and extends through the positioning mounting plate 5. The weight reduction groove 9 is used to reduce the weight of the positioning mounting plate 5, thereby making the positioning mechanism a lightweight structure, which facilitates the installation and positioning of the dust collection mechanism.

[0035] It also includes a positioning anti-slip pad 10, which is positioned on the side of the positioning mounting plate 5 near the positioning mounting block 8 and is fixedly connected to the positioning mounting plate 5. The positioning anti-slip pad 10 is fitted to the edge of the radar cover body. The positioning anti-slip pad 10 is used to increase the friction between the positioning mounting plate 5 and the radar cover body to prevent the positioning mechanism from sliding during the positioning process.

[0036] The clamping mechanism includes a connecting flexible rod 11 and a mounting clip 12. The connecting flexible rod 11 is located on one side of the side dust cover 1 and one end of it is fixedly connected to the side dust cover 1. The mounting clip 12 is located at the end of the connecting flexible rod 11 away from the side dust cover 1 and is movably connected to the connecting flexible rod 11. The clamping mechanism, through the cooperation of the connecting flexible rod 11 and the mounting clip 12, cooperates with the positioning mechanism to assemble the side dust cover 1 onto the side of the radar dome body. The connecting flexible rod 11 is used to flexibly connect the mounting clip 12 and the side dust cover 1. The structure of the connecting flexible rod 11 can be adjusted and changed according to the actual situation. The mounting clip 12 is used to clamp onto the side of the radar dome body, thereby cooperating with the positioning mechanism to assemble the side dust cover 1 onto the side of the radar dome body.

[0037] It also includes an angle adjustment assembly, which includes a connecting base 13, a connecting shaft 14, and a connecting mounting block 15. The connecting base 13 is located at the connection between the mounting clip 12 and the connecting flexible rod 11 and is fixedly connected to the mounting clip 12. The interior of the connecting base 13 is a hollow structure. The connecting shaft 14 is located at the end of the connecting base 13 away from the mounting clip 12 and is inserted into the connecting base 13. The portion of the connecting shaft 14 located at the connecting base 13 has a strip-shaped adjustment groove. The connecting mounting block 15 is located at the end of the connecting shaft 14 away from the connecting base 13 and is rotatably engaged with the connecting shaft 14. The mounting clip 12 is movably connected to the connecting flexible rod 11 through the angle adjustment assembly. The angle adjustment assembly is connected to the connecting base 13, connecting shaft 14, and connecting mounting block 15 through the connecting base 13, connecting shaft 14, and connecting flexible rod 11. The connecting shaft 14 and the connecting mounting block 15 cooperate to connect the connecting flexible rod 11 and the mounting clamp 12. The angle at the connection point between the connecting flexible rod 11 and the mounting clamp 12 can be adjusted according to actual needs. The connecting base 13 provides mounting support for the connecting shaft 14 and connects the connecting shaft 14 to the mounting clamp 12. The connecting shaft 14 connects the connecting base 13 to the connecting mounting block 15. The connecting mounting block 15 connects to the connecting base 13 under the action of the connecting shaft 14 and connects the connecting shaft 14 to the connecting flexible rod 11. The connecting base 13, the connecting shaft 14, and the connecting mounting block 15 together constitute a universally adjustable connection structure. A schematic diagram of the angle adjustment component of this invention is shown below. Figure 4 As shown.

[0038] The system also includes an adjusting screw 16 and an adjusting knob 17. The adjusting screw 16 is located on one side of the connecting base 13, corresponding to the connecting shaft 14, and is threadedly connected to the connecting base 13. One end of the adjusting screw 16, located inside the connecting base 13, passes through a strip-shaped adjusting groove on the connecting shaft 14 and is engaged with the connecting shaft 14 by a locking block. The adjusting knob 17 is located at the end of the adjusting screw 16 away from the connecting base 13 and is fixedly connected to the adjusting screw 16. The connecting screw is used to make an adjustable connection between the connecting shaft 14 and the connecting base 13. The tightness between the connecting shaft 14 and the connecting base 13 can be adjusted by rotating the connecting screw, thereby adjusting the connection state between the connecting screw and the connecting shaft 14. The adjusting knob 17 is used to drive the adjusting screw 16 to rotate. A schematic diagram of the interaction between the adjusting screw 16 and the adjusting knob 17 and the connecting shaft 14 is shown below. Figure 5 As shown.

[0039] It also includes a limiting abutment block 18, which is disposed in the middle of the connecting shaft 14 and threadedly connected to the connecting shaft 14. The limiting abutment block 18 is located between the connecting base 13 and the connecting mounting block 15. The limiting abutment block 18 is used to limit the connecting mounting block 15. The relative distance between the limiting abutment block 18 and the connecting mounting block 15 can be adjusted by adjusting the position of the limiting abutment block 18 on the connecting shaft 14, thereby limiting the relative rotation angle between the connecting mounting block 15 and the connecting shaft 14. A schematic diagram of the connection shaft 14 and the strip-shaped adjusting groove of the present invention is shown below. Figure 6 As shown.

[0040] A dust collection method for a radar dome edge-cutting dust collection device includes the following steps:

[0041] a. Assembly: Place the side dust cover 1 on the side of the radar dome body through the mounting groove at its lower part, and position the side of the radar dome body between the positioning mounting plate 5 and the positioning mounting block 8. Rotate the positioning screw 7 to make the positioning mounting block 8 and the positioning mounting plate 5 abut against the side of the radar dome body.

[0042] b. Clamping: Adjust the connecting flexible rod 11 and the angle adjustment component according to the actual situation so that the mounting clip 12 and the side dust cover 1 are at a certain angle and clamp the mounting clip 12 on the side of the radar dome body to perform double positioning of the side dust cover 1.

[0043] c. Edge vacuuming: When it is necessary to vacuum the edge of the radar dome, place the edge vacuum hood 1 at the corresponding position on the edge of the radar dome and connect the edge vacuum hood 1 to the external vacuuming equipment through the vacuuming corrugated pipe 2. When cutting the edge of the radar dome or performing other operations that generate dust, simply turn on the external vacuuming equipment.

[0044] d. Dust removal of the inner wall of the radome: When it is necessary to perform dust removal on the inner wall of the radome body, simply turn on the external dust removal equipment, attach the inner wall fitting cover 4 to the inner wall of the radome body, and then perform dust removal on the inner wall of the radome body.

[0045] During the vacuuming process, the clamping mechanism and positioning mechanism can be adjusted at any time to change the relative position between the vacuuming mechanism and the radar dome body.

[0046] Working principle:

[0047] The dust collection mechanism is connected to the radome body via a positioning mechanism and a clamping mechanism, and the dust collection mechanism is doubly positioned. The positioning mechanism is not affected by the edge structure of the radome body and can stably connect the dust collection mechanism to the radome body. The clamping mechanism, through its flexible structure, can adjust the distance between the clamping mechanism and the positioning mechanism in real time according to the processing progress and the processing status of the radome body. The clamping mechanism is also equipped with an angle adjustment component, which can increase the connection stability of the components in the clamping mechanism and improve the adjustment flexibility of the clamping mechanism. The dust collection mechanism is equipped with a dual dust collection structure, which can perform adaptive dust collection operations on the edge or inner wall of the radome body according to the usage requirements. The dust collection operation is flexible and is not affected by the shape of the radome body.

[0048] The beneficial effects of this invention are its simple structure, the inclusion of a dust-collecting mechanism adapted to the radome body, which effectively improves the dust-collecting efficiency during the radome body processing, and the dual dust-collecting structure, which can perform corresponding dust-collecting operations on different parts of the radome body according to usage requirements, offering diverse dust-collecting methods. A positioning mechanism allows for quick assembly of the dust-collecting mechanism with the radome body without manual lifting, saving labor. Furthermore, the structure of the dust-collecting mechanism can be adaptively adjusted during the positioning process, making it flexible to use. A clamping mechanism, in conjunction with the positioning mechanism, allows for relatively quick disassembly and assembly of the dust-collecting mechanism with the edge of the radome body, facilitating adjustments to the position of the dust-collecting device and enhancing its practicality.

[0049] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
