Description

Technical Field

[0001] This invention relates to the field of radome processing technology, and in particular, to a radome processing apparatus and processing method. Background Technology

[0002] An antenna is a transducer that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. A radome is a crucial component of an antenna, protecting the antenna system from the effects of wind, rain, snow, dust, and solar radiation, ensuring stable and reliable operation, reducing wear, corrosion, and aging, and extending its lifespan. During the manufacturing process, radomes typically require machining to achieve optimal physical properties.

[0003] Currently, Chinese Patent CN114619324A discloses a processing equipment for curved radomes, including a processing platform and a control unit. The control unit includes a control module and an identification module. The identification module can identify the curved surface model data of the radome to be processed and determine the processing method and sequence based on the model data. The processing platform includes processing components and a rotating tray, with the radome to be processed fixed on the rotating tray by a clamp. The control module can receive the aforementioned processing method and sequence and control the processing components to respond to the processing steps of the radome to be processed.

[0004] However, due to design requirements, manufacturing processes and other factors, the radome to be processed is often uneven in the circumferential direction. As a result, when a conventional fixture clamps and rotates the radome, the centrifugal force on the radome is relatively large, and it is easy for it to detach and be thrown out. Summary of the Invention

[0005] The first objective of this invention is to overcome the shortcomings of the prior art and provide a processing device for an antenna radome.

[0006] The first objective of this invention is achieved through the following technical solution:

[0007] A radome processing device includes a mounting table, on which a processing component and a rotating tray are mounted. The rotating tray is rotatable under the drive of a first driving component. A clamping component is provided on the end face of the rotating tray. The radome to be processed is fixed on the rotating tray by the clamping component. The clamping component includes a mounting post disposed at the center of the end face of the rotating tray. A plurality of telescopic rods are circumferentially disposed on the side wall of the mounting post. The telescopic rods extend outward to support the inner wall of the radome to be processed. A plurality of adjusting rods are also circumferentially disposed on the side wall of the mounting post. A counterweight is slidably disposed on the adjusting rod along the axial direction. The clamping component also includes a power component that can drive the counterweight to slide, thereby changing the center of gravity position of the radome to be processed when it rotates.

[0008] Several sets of the telescopic rods and several sets of the adjusting rods are arranged along the axial direction of the mounting column.

[0009] The mounting column has a mounting cavity. The power assembly includes a drive shaft rotatably disposed within the mounting cavity. The drive shaft is rotatable under the drive of the second driving member. A first bevel gear is disposed on the drive shaft. A plurality of second bevel gears are circumferentially rotatably disposed within the mounting cavity. The plurality of second bevel gears mesh with the first bevel gear. An adjusting rod is rotatably disposed on the mounting column. A lead screw nut is threaded onto the adjusting rod. A counterweight is fixedly disposed on the lead screw nut. A first electromagnetic clutch is disposed on the adjusting rod. The first electromagnetic clutch is used to transmit or disengage the transmission between the second bevel gears and the adjusting rod.

[0010] The telescopic rod includes a lead screw type telescopic rod, and a third bevel gear is also provided on the transmission shaft. A fourth bevel gear is provided on the lead screw of the telescopic rod. A plurality of the fourth bevel gears mesh with the third bevel gear. The third bevel gear and the first bevel gear are loosely engaged with the transmission shaft. A second electromagnetic clutch is provided on the transmission shaft at the opposite position of the third bevel gear and the first bevel gear. The second electromagnetic clutch is used to transmit or disengage the transmission between the transmission shaft and the third bevel gear and the first bevel gear.

[0011] The telescopic rod is equipped with an elastic block at its telescopic end.

[0012] It also includes a controller, and both the first electromagnetic clutch and the second electromagnetic clutch are electrically connected to the controller.

[0013] The telescopic rod is equipped with a contact switch at its telescopic end, and the contact switch is also electrically connected to the controller.

[0014] The second objective of this invention is to overcome the shortcomings of the prior art and provide a method for processing an antenna radome.

[0015] The second objective of this invention is achieved through the following technical solution:

[0016] The equipment for processing the radome, as described above, also includes the following steps:

[0017] S1. A model of the radome to be processed is acquired and generated using a scanning device;

[0018] S2. The actual center of gravity of the antenna radome to be processed is determined by analysis;

[0019] S3. Calculate the required sliding amount of the counterweights on the several adjustment rods. By using the different relative positions of the several counterweights inside the antenna radome to be processed, the center of gravity of the antenna radome to be processed can be adjusted to a balance center of gravity position closer to the rotation axis of the mounting column when it rotates.

[0020] S4. The antenna cover to be processed is fixed to the rotating tray by the support of several telescopic rods;

[0021] S5. The sliding amount calculated in S3 is imported into the control module of the antenna radome processing equipment, and the power component is controlled by the control module to drive the counterweight block to slide.

[0022] S6. The antenna radome to be processed is mechanically processed using the processing components.

[0023] The telescopic rod mentioned above is a positioning rod;

[0024] S4 further includes the following sub-steps:

[0025] S401. Mark the positioning points on the radome to be processed;

[0026] S402. Align the positioning point with the positioning rod, and then control several telescopic rods to support and fix the antenna cover to be processed.

[0027] The beneficial effects of this invention are:

[0028] 1. By adjusting the relative positions of several counterweights in the circumferential direction, the center of gravity of the radome to be processed can be adjusted during rotation. For example, the center of gravity can be adjusted to a position closer to the axis of rotation of the mounting column, thereby reducing the centrifugal force experienced by the radome during rotation. Compared with the prior art, the radome processing apparatus of the present invention can adjust the center of gravity of the radome to be processed during rotation, and is less likely to cause the radome to detach from the clamping member and be thrown out.

[0029] 2. The telescopic rod's support and clamping of the radome, as well as the sliding adjustment of the counterweight block to adjust the radome's center of gravity during rotation, are all driven by a power assembly, which greatly reduces the system complexity of the radome processing equipment. Furthermore, the power assembly uses only a second drive component as the power source, thus saving energy and making the radome processing device more energy-efficient and environmentally friendly.

[0030] 3. The second electromagnetic clutch allows for convenient switching between the telescopic rod for support and the counterweight for sliding adjustment. The first electromagnetic clutch allows for easy control of the counterweight on the target adjustment rod to respond to sliding movements, while the counterweight on the adjustment rod that does not require adjustment remains in place. Furthermore, the electromagnetic clutch is easier to control remotely, significantly improving the automation level of the radome processing device. Attached Figure Description

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] like Figure 1 , Figure 2 , Figure 3As shown, a radome processing device includes a mounting table 1, on which a processing component 2 and a rotating tray 3 are mounted. Similar to existing technologies, the processing component 2 can be a multi-axis workpiece, such as a grinding device or a laser device; while the rotating tray 3 can be driven to rotate by a first driving component 4. Correspondingly, the rotating tray 3 is also provided with clamping components 5 for holding and fixing the radome to be processed. Therefore, the rotating tray 3 can drive the radome to be processed to rotate together, thereby facilitating the machining of the radome by the processing component 2.

[0038] It's important to understand that rotating objects generate centrifugal force, the magnitude of which depends on the radius of rotation, the rotational speed, and the object's mass. More specifically, if an object is unbalanced during rotation—meaning its center of gravity is not on the axis of rotation—an unbalanced force will be generated, leading to centrifugal force. Furthermore, the magnitude of the centrifugal force is directly proportional to the amount of unbalance; as the unbalance increases, the centrifugal force also increases.

[0039] Due to design requirements and manufacturing processes, the radome to be processed is often uneven in the circumferential direction. As a result, when the conventional clamping component 5 clamps and rotates the radome to be processed, the centrifugal force on the radome to be processed is large, and it is easy for it to detach and be thrown out.

[0040] To address the aforementioned issues, the clamping component 5 disclosed herein includes a mounting post 6 positioned at the center of the end face of the rotating tray 3, with several telescopic rods 7 circumferentially arranged on the side wall of the mounting post 6. During clamping, the telescopic rods 7 extend to support and fix the inner wall of the antenna radome to be processed. Additionally, several adjusting rods 8 are circumferentially arranged on the side wall of the mounting post 6, with a counterweight 9 slidably mounted on each adjusting rod 8 along its axial direction. Furthermore, the clamping component 5 includes a power assembly 10, which drives the counterweight 9 to slide.

[0041] It is understandable that by controlling the counterweights 9 on different adjusting rods 8 to slide in different relative positions, the center of gravity position of the antenna radome under processing can be changed when it rotates. For example, the center of gravity position can be adjusted to the balance center of gravity position close to the rotation axis of the mounting column 6 (that is, the above-mentioned imbalance is reduced), thereby reducing the centrifugal force on the antenna radome under processing when it rotates, so that the antenna radome under processing is less likely to detach from the clamping member 5 and be thrown out.

[0042] For example, multiple sets of telescopic rods 7 and multiple sets of adjusting rods 8 are arranged along the axial direction of the mounting column 6. Multiple sets of telescopic rods 7 can achieve more stable support for the radome; while multiple sets of adjusting rods 8 increase the adjustability of the counterweight 9 along the axial direction of the mounting column 6, making it easier to adjust the center of gravity of the radome to a balanced center of gravity position close to the rotation axis of the mounting column 6 when it rotates.

[0043] In some embodiments, the mounting column 6 has a mounting cavity 11, and the power assembly 10 includes a drive shaft 12 rotatably disposed in the mounting cavity 11. The drive shaft 12 can rotate under the drive of the second drive member 13. For example, both the first drive member 4 and the second drive member 13 can be selected as motors, and the second drive member 13 can be disposed inside the rotating tray 3.

[0044] Specifically, a first bevel gear 14 is mounted on the drive shaft 12, and a plurality of second bevel gears 15 are rotatably mounted circumferentially within the mounting cavity 11, with each of the second bevel gears 15 meshing with the first bevel gear 14. The aforementioned plurality of adjusting rods 8 are rotatably mounted on the mounting post 6, and each adjusting rod 8 has a portion extending into the mounting cavity 11. It can be seen that there is a one-to-one correspondence between the plurality of adjusting rods 8 and the plurality of second bevel gears 15.

[0045] More specifically, each adjusting rod 8 is provided with a first electromagnetic clutch 17 on the portion that extends into the mounting cavity 11. The first electromagnetic clutch 17 can engage with the corresponding second bevel gear 15, thereby transmitting the rotational driving force of the second bevel gear 15 on the adjusting rod 8. Of course, the first electromagnetic clutch 17 can also disengage from the corresponding second bevel gear 15, thereby disengaging the rotational driving force of the second bevel gear 15 on the adjusting rod 8.

[0046] The adjusting rod 8, located outside the mounting column 6, is threaded and connected to a lead screw nut 16. The counterweight 9 is fixedly mounted on the lead screw nut 16. It can be understood that the adjusting rod 8 essentially constitutes a lead screw in the prior art. When the first electromagnetic clutch 17 is engaged, the power of the second driving member 13 is transmitted to the adjusting rod 8 through the engagement of the first bevel gear 14, the second bevel gear 15, and the first electromagnetic clutch 17. Subsequently, the adjusting rod 8 rotates, thereby driving the lead screw nut 16 to move the counterweight 9.

[0047] For example, after the telescopic rod 7 has finished clamping the radome, the first electromagnetic clutch 17 on different adjusting rods 8 can be controlled to engage with the corresponding second bevel gear 15, thereby achieving different sliding distances of several counterweights 9, so as to adjust the center of gravity position of the radome to be processed when it rotates.

[0048] In some embodiments, the telescopic rod 7 is a lead screw type telescopic rod 7, that is, the telescopic rod 7 includes a lead screw and an ejector end connected to the lead screw by a nut. A third bevel gear 18 is also provided on the aforementioned transmission shaft 12, and a fourth bevel gear 19 is provided on the lead screw of each telescopic rod 7, with several fourth bevel gears 19 meshing with the third bevel gear 18. Since several telescopic rods 7 can use the same ejection stroke to support the radome when ejected, the aforementioned first electromagnetic clutch 17 is not required on the lead screw of the telescopic rod 7. Of course, depending on the clamping requirements, a first electromagnetic clutch 17 can also be provided on the lead screw of the telescopic rod 7 to achieve different ejection strokes for several telescopic rods 7. Preferably, an elastic block 21 can be provided at the ejector end of the telescopic rod 7, for example, the elastic block 21 can be a rubber block. The elastic block 21 can increase the supporting force of the telescopic rod 7 on the inner wall of the radome and also prevent collision damage to the inner wall of the radome.

[0049] More specifically, both the third bevel gear 18 and the first bevel gear 14 are loosely fitted with the drive shaft 12, and a second electromagnetic clutch 20 is provided on the drive shaft 12 at the position opposite to the third bevel gear 18 and the first bevel gear 14. Similar to the first electromagnetic clutch 17, the second electromagnetic clutch 20 can realize the transmission connection or disengagement between the drive shaft 12 and the third bevel gear 18 and the first bevel gear 14.

[0050] For example, when the radome needs to be clamped, the third bevel gear 18 engages with the corresponding second electromagnetic clutch 20, while the first bevel gear 14 disengages from the corresponding second electromagnetic clutch 20. At this time, the lead screw of the telescopic rod 7 will rotate under the transmission of the third bevel gear 18 and the fourth bevel gear 19, thereby driving its top end to support the inner wall of the radome.

[0051] When the radome needs to be adjusted to change its center of gravity during rotation, the first bevel gear 14 engages with the corresponding second electromagnetic clutch 20, while the third bevel gear 18 disengages from the corresponding second electromagnetic clutch 20. At this time, the adjusting rod 8 will rotate under the combined transmission of the first bevel gear 14, the second bevel gear 15, and the first electromagnetic clutch 17, thereby driving the counterweight 9 to slide and change its relative position to adjust the center of gravity of the radome during rotation.

[0052] Preferably, the radome processing equipment may also include a controller, and both the first electromagnetic clutch 17 and the second electromagnetic clutch 20 are electrically connected to the controller. In addition, a contact switch 22 is provided on the top end of the telescopic rod 7, and this contact switch 22 is also electrically connected to the controller.

[0053] Therefore, radome processing equipment can have the following usage process:

[0054] The antenna cover to be processed is placed on the outside of the mounting post 6. Then the controller controls the third bevel gear 18 to engage with the corresponding second electromagnetic clutch 20, while the first bevel gear 14 is disengaged from the corresponding second electromagnetic clutch 20. Then several telescopic rods 7 are pushed out to support and fix the antenna cover.

[0055] When all the contact switches 22 on the top end of the telescopic rod 7 are pressed, the controller controls the first bevel gear 14 to engage with the corresponding second electromagnetic clutch 20, while the third bevel gear 18 is disengaged from the corresponding second electromagnetic clutch 20.

[0056] Meanwhile, the controller can also control the corresponding first electromagnetic clutch 17 to engage or disengage, so that the counterweights 9 on different adjusting rods 8 can slide to different relative positions, thereby changing the center of gravity position of the antenna radome to be processed when it rotates.

[0057] Example 2:

[0058] A method for manufacturing an radome, comprising the radome manufacturing equipment described in Embodiment 1, and further comprising the following steps:

[0059] S1. A model of the radome to be processed is acquired and generated using a scanning device;

[0060] S2. The actual center of gravity of the antenna radome to be processed is determined by analysis;

[0061] S3. Calculate the required sliding amount of the counterweights 9 on the several adjusting rods 8. By using the different relative positions of the several counterweights 9 inside the antenna radome to be processed, the center of gravity of the antenna radome to be processed can be adjusted to a balance center of gravity position closer to the rotation axis of the mounting column 6.

[0062] S4. The antenna cover to be processed is fixed to the rotating tray 3 by the support of several telescopic rods 7;

[0063] S5. The sliding amount calculated in S3 is imported into the control module of the antenna radome processing equipment, and the power component 10 is controlled by the control module to drive the counterweight 9 to slide.

[0064] S6. The antenna cover to be processed is mechanically processed by the processing component 2.

[0065] Among them, the control module in S5 is the controller in Embodiment 1. The controller can control the engagement or disengagement of different first electromagnetic clutches 17 according to the sliding amount calculated in S3, and can also control the engagement time of the first electromagnetic clutches 17, thereby adjusting the counterweight 9 on the target adjustment rod 8 to the relative position of the required sliding amount, so as to complete the adjustment of the center of gravity position when the antenna radome to be processed rotates.

[0066] For example, one of its telescopic rods 7 can be set as a positioning rod;

[0067] S4 also includes the following sub-steps:

[0068] S401. Mark the positioning points on the radome to be processed;

[0069] S402. Align the positioning point with the positioning rod, and then control several telescopic rods 7 to support and fix the antenna cover to be processed.

[0070] It is understandable that by using positioning points and positioning rods, the actual orientation of the radome to be processed and the orientation of several adjusting rods 8 can be quickly and conveniently determined, ensuring that when several counterweights 9 have finished sliding, the center of gravity of the radome to be processed can more accurately match the preset balance center of gravity position during rotation. For example, the positioning points can be erasable, marked with colored ink.

[0071] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
