Description

Technical Field

[0001] This utility model relates to the field of waveguide antenna technology, and in particular to a fixing clamp and waveguide welding device. Background Technology

[0002] Waveguide antennas are key components used to transmit high-frequency electromagnetic waves and are widely used in radar, satellite communications, aerospace, and other fields. Waveguide antennas are typically made from sheet metal, and their internal structure significantly impacts electromagnetic wave transmission efficiency. Therefore, high requirements are placed on the processing precision of the sheet metal, the quality of connections, and the welding process.

[0003] In existing technologies, the manufacturing of waveguide antenna plates typically involves splicing multiple metal plates and forming a complete waveguide cavity or antenna array through welding. To ensure welding quality, fixtures are needed to precisely position and fix the plates before welding to ensure uniform gaps between plates and stable weld quality. However, current common fixture structures can usually only clamp two plates at a time, and cannot clamp multiple plates simultaneously. Since existing technologies can only weld two plates at a time, the fixture needs to be readjusted and new plates clamped after each set of welding is completed, increasing repetitive operations in the welding process and reducing production efficiency. Splicing errors also accumulate during the progressive welding process. The plates welded first may experience slight deformation due to thermal stress, and existing fixtures cannot fix multiple plates in the same process, leading to a gradual accumulation of assembly errors in subsequent plates, affecting the dimensional accuracy of the final structure. Because it is impossible to fix all plates simultaneously, local stress concentration may occur during welding, resulting in unevenness, warping, or deformation, which in turn affects the electromagnetic sealing performance and signal transmission efficiency of the waveguide. The existing fixtures need to be readjusted every time a new plate is welded, which inevitably leads to positioning errors, thus affecting the overall parallelism and perpendicularity of the waveguide antenna cavity.

[0004] Patent "A Novel Processing Fixture and Processing Device for Antenna Waveguide Plates" (Authorization Announcement No. CN222244437U, hereinafter referred to as Prior Art 1) discloses a fixture for waveguide plates. The main technical principle of Prior Art 1 is to provide a novel processing fixture and processing device for antenna waveguide plates to solve the problem that existing waveguide fixtures cannot adaptably clamp and process waveguide plates of various shapes. This fixture is designed with a pressure-applying component arranged around the outer periphery of a protrusion on the base, fully covering the area where the waveguide plate is placed on the base. It can adaptably adjust the position, quantity, and height of the pressure-applying component according to preset intervals for various shapes of the antenna waveguide plate before clamping the waveguide plate. However, although the fixture in Prior Art 1 can achieve adaptable clamping of waveguide plate shapes, its structure is relatively complex, adjusting the position, quantity, and height of the pressure-applying component requires considerable time, and the accuracy and stability of the pressure-applying component may be affected after repeated use. Furthermore, the fixture in the prior art 1 does not solve the problem of clamping multiple plates at the same time, still requires step-by-step welding, resulting in low production efficiency, and problems such as the accumulation of splicing errors and minor deformation caused by thermal stress.

Unless otherwise specified, embodiments of the present invention and the various features thereof can be combined with each other, all within the protection scope of the present invention.

[0036] Example 1

[0037] Please see Figure 1 This utility model embodiment provides a fixing fixture. Traditional fixtures can usually only fix one waveguide plate 200 at a time, while the fixing fixture in this embodiment can fix two or more waveguide plates 200 at the same time, completing the welding operation of multiple waveguide plates 200 in the same process, improving the consistency of product welding and improving product processing efficiency.

[0038] Furthermore, the fixing fixture includes a first frame 100 and a clamping area 110 disposed on the first frame 100; the clamping area 110 is provided with a receiving member 111 for placing waveguide plates 200 to be processed, and at least two waveguide plates 200 to be processed can be placed on the receiving member 111. The clamping area 110 has a certain length to accommodate multiple waveguide plates 200 arranged side by side, so that multiple waveguide plates 200 can be fixed on the clamping area 110 at the same time, so that the welding of waveguide plates 200 in the same batch has consistency, thereby improving the overall processing quality and production efficiency.

[0039] Furthermore, the design of the receiving component 111 allows the waveguide plate 200 to be placed stably, avoiding displacement or shaking that may occur during welding, further ensuring the accuracy and stability of the welding. The surface of the receiving component 111 can also be provided with anti-slip textures or adsorption devices to enhance the fixing effect on the waveguide plate 200 and prevent it from slipping or moving during processing. The length of the clamping area 110 can be adjusted according to actual needs to accommodate the processing requirements of different quantities and sizes of waveguide plates 200, improving the flexibility and applicability of the fixing fixture.

[0040] The clamping area 110 has several pairs of first clamping assemblies 120 that are detachably mounted to the first frame 100 on both sides; each waveguide plate 200 is clamped by at least one pair of the first clamping assemblies 120 arranged on both sides of the clamping area 110; wherein each waveguide plate 200 is also fixed to the receiving member 111 by a second clamping assembly 130.

[0041] Please see Figure 1 In use, the first clamping assembly 120 clamps the waveguide plates 200 at the positions requiring welding, while the second clamping assembly 130 clamps each waveguide plate 200 individually. The two clamping assemblies operate simultaneously, and both can be adjusted to accommodate the number of waveguide plates 200, enabling welding of two or more waveguide plates 200 together. During clamping, the first clamping assembly 120 precisely aligns and fixes the two sides of the contact areas between the waveguide plates 200 to ensure tight joints and accurate positioning during welding. The second clamping assembly 130 secures each waveguide plate 200 as a whole, preventing unnecessary movement due to heat or other factors during welding. This dual-clamping design not only improves welding accuracy and stability but also effectively shortens clamping and debugging time, further enhancing production efficiency.

[0042] Furthermore, the adjustable clamping components allow this fixture to flexibly handle the processing needs of waveguide 200 plates of varying quantities and sizes. Whether for small-batch or large-scale production, efficient and precise welding operations can be achieved through simple adjustments. This design not only enhances the fixture's versatility and practicality but also provides users with a more convenient and efficient operating experience.

[0043] Further, please see Figure 3The first clamping assembly 120 includes a mounting base 121 and a pressure arm 122 and a pressure handle 123 hinged to the mounting base 121, and a clamping member 124 is provided at the end of the pressure arm 122. The pressure arm 122 and the pressure handle 123 are hinged at their intersection; by adjusting the angle between the pressure handle 123 and the pressure arm 122, the clamping member 124 is in a clamped or released state with the waveguide plate 200.

[0044] In use, users can easily adjust the angle of the pressure handle 123 according to actual needs, thereby controlling the position of the clamping element 124 at the end of the pressure arm 122. When the pressure handle 123 is lifted, the pressure arm 122 rotates accordingly, and the clamping element 124 fits tightly against the waveguide plate 200, providing a stable clamping force. Conversely, when it is necessary to release the waveguide plate 200, simply pry the pressure handle 123 downwards, and the pressure arm 122 will automatically spring back under the action of the hinge point, and the clamping element 124 will also be released, allowing the waveguide plate 200 to be easily removed or repositioned. This design not only simplifies the operation process but also greatly improves work efficiency. At the same time, the clamping element 124 is made of wear-resistant and high-temperature-resistant materials, ensuring that it can maintain a stable clamping effect during long-term, high-intensity welding operations, effectively extending the service life of the fixture.

[0045] Further, please see Figure 2 The second clamping assembly 130 includes a hinge seat 131 and a pressure rod 132 hinged to the hinge seat 131; a pressure spring is also provided at the connection end between the hinge seat 131 and the pressure rod 132. The second clamping assembly 130 also includes an auxiliary pressure plate 133; the auxiliary pressure plate 133 includes a first pressure surface 134 and an auxiliary pressure plate 135, and a partition 136 is provided between the first pressure surface 134 and the auxiliary pressure plate 135. The auxiliary pressure plate 133 is pressed against the waveguide plate 200 by a pair of pressure rods 132 of the second clamping assembly 130 disposed on both sides of the clamping area 110.

[0046] During use, due to the preload of the clamping spring, the pressure rod 132 is always in a downward state. When it is necessary to apply pressure to the waveguide plate 200 through the second clamping assembly 130, the auxiliary clamping plate 133 is first placed on the waveguide plate 200, and then the pressure rods 132 of the second clamping assembly 130, which are located on both sides of the waveguide plate 200, are lifted. Subsequently, the pressure rods 132 are respectively placed on the first clamping surface 134 and the auxiliary clamping plate 135 to clamp the auxiliary clamping plate 133. At this time, the elastic force of the clamping spring acts on the pressure rod 132, so that the pressure rod 132 applies a stable clamping force to the auxiliary clamping plate 133. Since the auxiliary clamping plate 133 includes the first clamping surface 134 and the auxiliary clamping plate 135, and a partition 136 is provided between them, this design can ensure that the waveguide plate 200 is subjected to uniform force when clamped, and avoid excessive local pressure that could damage the waveguide plate 200. Meanwhile, the design of the first clamping surface 134 and the auxiliary clamping plate 135 increases the contact area with the waveguide plate 200, improving clamping stability. In actual operation, users can flexibly adjust the position and angle of the auxiliary clamping plate 133 according to the size and shape of the waveguide plate 200 to ensure that the waveguide plate 200 is firmly clamped. This design of the second clamping assembly 130 not only improves the adaptability and flexibility of the fixture, but also further enhances the efficiency and quality of welding operations.

[0047] Further, please see Figure 2 The end of the pressure rod 132 is also provided with a pressure block 137, which is used to directly contact and apply pressure to the auxiliary clamping plate 133 to enhance the clamping effect. The pressure block 137 is made of wear-resistant, high-strength material to ensure that it is not easily damaged during long-term use. In addition, the design of the pressure block 137 also takes into account the feature of easy replacement. When the pressure block 137 wears out due to long-term use, the user can easily remove it and replace it with a new one, thereby extending the service life of the entire fixture. At the same time, the connection between the pressure rod 132 and the pressure block 137 has also been carefully designed to ensure a stable connection and easy adjustment to meet the clamping requirements of different waveguide plates 200. This meticulous design makes the entire fixture more stable and reliable during operation, further improving the safety and efficiency of welding operations. Furthermore, the installation of the pressure block 137 creates a gap between the pressure rod 132 and the waveguide plate 200, making it easy to manually lift the pressure rod 132 when clamping.

[0048] Example 2

[0049] Please see Figure 1 , Figure 4 and Figure 5 This utility model embodiment provides a waveguide welding device, which is disposed on one side of a fixing fixture and is used to perform welding operations on the waveguide plate 200 on the fixing fixture.

[0050] Please see Figure 4 The waveguide welding device includes a second frame 300, a displacement mechanism, and a welding assembly 340 mounted on the displacement mechanism. The displacement mechanism includes a first moving mechanism 310, a second moving mechanism 320, and a third moving mechanism 330. The welding assembly 340 covers the clamping area 110 via the first moving mechanism 310, the second moving mechanism 320, and the third moving mechanism 330, and welds the waveguide plate 200 disposed within the clamping area 110. The welding assembly 340 is mounted on the third moving mechanism 330 and includes a welding torch 341 positioned at a preset angle to the third moving mechanism 330. The angle and welding position of the welding torch 341 can be adjusted by the displacement mechanism to ensure that the welding torch 341 can accurately align with the welding area of ​​the waveguide plate 200. The first moving mechanism 310 and the second moving mechanism 320 work together to enable the welding assembly 340 to move flexibly in the horizontal and vertical planes, thereby covering the entire clamping area 110. This multi-layered, multi-dimensional displacement design not only improves the precision and flexibility of welding but also greatly enhances the adaptability and practicality of the waveguide welding device. During the welding process, the welding assembly 340 can complete the welding operation stably and efficiently, ensuring a high-quality connection of the waveguide plate 200.

[0051] Furthermore, the first moving mechanism 310 is mounted on the second frame 300 and includes a first motor 311 and a lead screw 312 driven by the first motor 311; the lead screw 312 can rotate based on a first bearing seat 313 and a second bearing seat 314 mounted at both ends of the second frame 300; a first moving seat 315 is also mounted on the lead screw 312 via a nut seat; the first moving seat 315 can move based on a moving guide rail 316 mounted on the second frame 300.

[0052] In use, the first motor 311 is started, driving the lead screw 312 to rotate. As the lead screw 312 rotates, the nut seat moves along the threaded trajectory of the lead screw 312, thereby causing the first moving seat 315 to slide smoothly on the moving guide rail 316. This design ensures that the first moving seat 315 can move accurately and stably along a predetermined path. In use, the operator can precisely adjust the speed and direction of the first motor 311 through the control system, thereby achieving precise control over the moving speed and direction of the first moving seat 315. This control method not only improves the accuracy of welding operations but also makes the entire welding process more automated and intelligent. In addition, the first moving mechanism 310 has a compact and robust structural design, capable of withstanding the vibrations and impacts generated during welding, ensuring the stability and reliability of the welding operation. Since the second moving mechanism 320 is mounted on the first moving seat 315, the second moving mechanism 320 moves based on the first moving mechanism 310.

[0053] Furthermore, the second moving mechanism 320 includes a first guide rail frame 321 disposed on the first moving seat 315, and a second moving seat 322 that moves based on the first guide rail frame 321; a first cylinder 323 is provided on the top of the first guide rail frame 321, and the piston rod of the first cylinder 323 is connected to the second moving seat 322 and can drive the second moving seat 322 to move.

[0054] In use, the first cylinder 323 is activated, its piston rod extending or retracting, thereby pushing or pulling the second movable seat 322 to move on the first guide rail 321. This cylinder-driven movement method features fast response and precise positioning. As the piston rod of the first cylinder 323 extends or retracts, the second movable seat 322 can quickly and accurately reach the predetermined position. This design allows the second movable seat 322 to flexibly adjust its position during welding operations to meet different welding needs. Simultaneously, the first guide rail 321 provides a stable movement path for the second movable seat 322, ensuring its smoothness and accuracy during movement. During use, the operator can precisely control the extension and retraction of the first cylinder 323 through the control system, thereby achieving precise control of the movement distance of the second movable seat 322. This control method further improves the accuracy and efficiency of welding operations, making the entire welding process more flexible and controllable. Since the third moving mechanism 330 is mounted on the second movable seat 322, the third moving mechanism 330 can move based on the second moving mechanism 320.

[0055] Further, please see Figure 4 and Figure 5The third moving mechanism 330 includes a second guide rail frame 331 disposed on the second moving seat 322; the second guide rail frame 331 is provided with a third moving seat 332, the third moving seat 332 is driven by a second cylinder 333 disposed on the second guide rail frame 331, so that the third moving seat 332 moves based on the second guide rail frame 331; the welding assembly 340 is disposed on the third moving seat 332.

[0056] In operation, the second cylinder 333 is activated, causing its piston rod to extend or retract. This action drives the third movable seat 332 to move along the second guide rail 331. The second cylinder 333 also boasts fast response and precise positioning, ensuring that the third movable seat 332 can move quickly and accurately to the predetermined position. This design not only increases the flexibility of welding operations but also meets more complex welding requirements. The second guide rail 331 provides another stable movement path for the third movable seat 332, ensuring its smoothness and accuracy during movement. The operator can precisely control the extension and retraction of the second cylinder 333 through the control system, thereby precisely controlling the movement distance of the third movable seat 332. This control method further improves the precision and efficiency of welding operations, making the welding process more flexible and controllable. Finally, the welding assembly 340 is installed on the third movable seat 332. As the third movable seat 332 moves, the welding assembly 340 can accurately reach the welding position for precise welding operations. The welding assembly 340 is disposed on the third moving assembly, and therefore the welding assembly 340 moves as the third moving assembly moves.

[0057] Furthermore, the welding torch 341 is mounted on the third movable base 332 via a welding torch clamp 343, and the welding assembly 340 also includes a second motor 342 mounted on the third movable base 332. The second motor 342 is fixedly connected to the welding torch clamp 343 to drive the welding torch clamp 343 to rotate, thereby adjusting the angle of the welding torch 341.

[0058] In use, the operator can start the second motor 342 through the control system. The second motor 342 transmits power to the welding torch clamp 343, driving the clamp to rotate. The rotation of the clamp causes the welding torch 341 to rotate, thus achieving precise adjustment of the welding torch 341's angle. This design not only increases the flexibility of welding operations but also allows the welding assembly 340 to adapt to welding requirements at different angles. The operator can precisely control the rotation angle of the second motor 342 according to the specific shape and position of the workpiece, thereby precisely adjusting the angle of the welding torch 341 to ensure the accuracy and efficiency of the welding operation. During the welding process, the welding torch 341, with the movement of the third moving base 332 and the rotation of the clamp 343, can accurately reach the predetermined welding position and perform welding operations at the optimal angle, thereby improving welding quality and efficiency.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
