Description
Technical Field
[0001] This utility model relates to the field of hard waveguide component technology, and specifically to a hard waveguide component debugging fixture. Background Technology
[0002] A rigid waveguide is a hollow metal tube used to transmit radio waves. Bending rigid waveguides often results in problems where the electrical performance, especially the voltage standing wave ratio (VSWR), exceeds the expected value due to factors such as processing errors. For example, even a slight deformation of the cross-section of the bent or torn part of the waveguide can cause the propagation constant to differ from that of the undeformed waveguide, thus causing a mismatch.
[0003] In existing technologies, the processing and adjustment of rigid waveguide components, especially at bends, face numerous technical challenges: rigid waveguides are prone to dimensional deviations and shape deformations during bending. Due to the elastic recovery characteristics of metallic materials, the bent waveguides often fail to fully meet design requirements, resulting in excessive voltage standing wave ratios (VSWR).
[0004] Existing debugging processes are inefficient. Typically, a pair of clamps are used to hold the rigid waveguide component to be tested. However, when a large amount of pressure is applied to the bent side of the rigid waveguide component, it is easy for the rigid waveguide component to shift, causing the pressure direction to deviate from the design requirements and aggravating the deformation of the rigid waveguide component. Utility Model Content
[0005] The purpose of this invention is to overcome the problems in the prior art and provide a rigid waveguide assembly debugging fixture to ensure that the workpiece does not shift during the debugging process.
[0006] This utility model provides a rigid waveguide assembly debugging fixture, including a base, two clamping plates fixedly installed on the top wall of the base, and a rigid waveguide assembly snapped between the two clamping plates. The fixture is characterized in that a snap-fit post is rotatably connected to the top of the clamping plate away from the curved surface of the rigid waveguide assembly; a pressing assembly is provided on the side wall of the base, the pressing assembly including a guide surface, a positioning rod, and a pressing screw; the guide surface is an arc shape concentric with the snap-fit post; the positioning rod is vertically positioned with its bottom end slidably connected to the guide surface; the snap-fit post is fixedly connected to the top end of the positioning rod via a pull rod, forming a stable triangular support structure; the pressing screw is vertically slidably disposed within the positioning rod, and its end abuts against the curved surface of the rigid waveguide assembly.
[0007] Preferably, the guide surface has a sliding groove along its arc direction, a sliding block is slidably embedded in the sliding groove, the sliding block is fixedly connected to the bottom end of the positioning rod, a moving groove is vertically through the positioning rod, the extrusion screw is slidably disposed in the moving groove, a positioning groove is formed inside the moving groove, a positioning disk is slidably installed inside the positioning groove, the positioning disk is threaded onto the extrusion screw, and a pressure head is fixedly installed on one end of the extrusion screw near the base.
[0008] Preferably, the guide surface is a precisely machined arc shape, and the center of the arc of the guide surface coincides with the center of the movement trajectory of the snap-fit post, ensuring the stability of the system and the accuracy of the force direction during the force application process.
[0009] Preferably, a rotating disk is fixedly installed on the end of the extrusion screw away from the base. The surface of the rotating disk is provided with anti-slip texture, and its diameter is more than a multiple of the diameter of the extrusion screw, so as to facilitate the operator to apply force accurately.
[0010] Preferably, a high-precision pressure sensor is provided on the surface of the pressure head that contacts the hard waveguide assembly. The pressure sensor is electrically connected to a digital display device mounted on the base to display the applied pressure value in real time.
[0011] Preferably, the inner side of the clamping plate is provided with a quick-replaceable adapter block, which is fixed to the clamping plate by magnetic connection or pin connection, and the shape of the adapter block matches the outer contour of different models of hard waveguide components.
[0012] Preferably, a linear guide rail structure is provided between the positioning disk and the positioning groove to ensure that the positioning disk slides smoothly in the positioning groove, and the surface of the positioning disk is hardened to improve wear resistance.
[0013] Preferably, the pressure head adopts a replaceable design, is connected to the extrusion screw via a threaded connection or a quick-release structure, and is available in a variety of pressure heads of different shapes and materials to meet the debugging needs of different hard waveguide components.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a rigid waveguide assembly debugging fixture, which constructs a stable debugging platform through the synergistic action of a base, clamping plates, and a pressing assembly. The two clamping plates fixedly installed on the top of the base can firmly engage the rigid waveguide assembly, ensuring that the workpiece does not shift during debugging. The guide surface is formed on the side wall of the base; this structural design ensures the accuracy and stability of the applied force direction.
[0015] The triangular support structure significantly improves the stability of the entire debugging fixture. When the extrusion screw applies pressure to the rigid waveguide assembly, the reaction force is transmitted through the positioning rod.

The drawings in this utility model are not strictly drawn to scale; the specific dimensions and quantity of each structure can be determined according to actual needs. The drawings described in this utility model are only structural schematic diagrams.
[0022] This utility model provides a hard waveguide component debugging fixture, such as Figures 1-3 As shown, the system includes a base 1, with two clamping plates 2 fixedly installed on the top wall of the base 1. A rigid waveguide assembly is snapped between the two clamping plates 2. Multiple connectors 14 are fixedly installed on the side wall of the base 1. An extrusion assembly, including a guide surface 15, is provided on the side wall of the base 1. A sliding groove 3 is formed on the side wall of the guide surface 15, and a sliding block 5 is slidably installed inside the sliding groove 3. A positioning rod 4 is fixedly installed on the side wall of the sliding block 5, and a moving groove 6 is formed on the side wall of the positioning rod 4. A positioning groove 9 is formed inside the moving groove 6. A positioning disk 10 is slidably installed inside the positioning groove 9. An extrusion screw 7 is threaded through the inside of the positioning disk 10, and a pressure head 8 is fixedly installed on one end of the extrusion screw 7 near the base 1.
[0023] In this embodiment, the fixture constructs a stable debugging platform through the synergistic action of the base 1, the clamping plate 2, and the extrusion assembly. The two clamping plates 2 fixedly installed on the top of the base 1 can firmly clamp the rigid waveguide assembly, ensuring that the workpiece does not shift during the debugging process. The guide surface 15 is opened on the side wall of the base 1, and the sliding groove 3 is opened on the side wall of the guide surface 15. The sliding block 5 is slidably installed inside. This structural design ensures the accuracy and stability of the force application direction.
[0024] The entire extrusion assembly's operation process achieves precise mechanized control. By rotating the extrusion screw 7, the operator can intuitively and accurately control the pressure and feed speed of the pressure head 8 on the hard waveguide assembly, realizing quantitative control of the debugging process. Compared with the traditional method that relies on the operator's experience and feel, this device standardizes the debugging process, significantly improving product consistency and pass rate.
[0025] Preferred, such as Figures 1-2As shown, a pull rod 12 is fixedly installed on the side wall of the positioning rod 4. A snap-fit post 13 is rotatably installed on the end of the pull rod 12 away from the positioning rod 4. The snap-fit post 13 is slidably installed on the side wall of the adjacent clamping plate 2 to form a stable triangular support structure.
[0026] In this embodiment, the triangular support structure significantly improves the stability of the entire debugging fixture. When the compression screw 7 applies pressure to the hard waveguide assembly, the reaction force is transmitted through the positioning rod 4. The triangular support formed by the pull rod 12 and the locking post 13 can effectively counteract this reaction force, prevent the positioning rod 4 from tilting or shifting, and ensure the accuracy of the force direction. This stability is crucial for the high-precision debugging of the hard waveguide assembly, because any deviation in the force direction may lead to unsatisfactory debugging results.
[0027] The sliding installation of the locking pin 13 on the side wall of the clamping plate 2 ensures the stability of the support without hindering the necessary movement of the positioning rod 4. When it is necessary to adjust the position of the pressure head 8, the locking pin 13 can slide along the side wall of the clamping plate 2, allowing the positioning rod 4 to change its angle as needed while maintaining stable support.
[0028] The rotating snap-fit post 13 reduces frictional resistance during movement, making operation smoother. This design also reduces wear and extends the service life of the clamp during long-term use, thus significantly improving the durability and reliability of the entire support structure.
[0029] Preferred, such as Figures 1-2 As shown, the guide surface 15 is a precisely machined arc shape, and the center of the arc of the guide surface 15 coincides with the center of the movement trajectory of the snap-fit post 13, ensuring the stability of the system and the accuracy of the force direction during the force application process.
[0030] In this embodiment, the precisely machined arc-shaped guide surface 15 provides an ideal track for the movement of the sliding block 5. Compared with simple planar guidance, the arc-shaped guide surface 15 can better control the force application angle, so that the pressure head 8 always approaches the hard waveguide assembly along the optimal path.
[0031] The design of aligning the center of the arc of the guide surface 15 with the center of the movement trajectory of the locking post 13 ensures the coordination of the force application system. Throughout the entire debugging process, regardless of the angle of the positioning rod 4, the direction of force application remains ideal, improving the accuracy of the debugging.
[0032] The precisely machined guide surface 15 has a high surface finish and a low coefficient of friction, which makes the movement of the sliding block 5 more stable. This stable movement characteristic is crucial for achieving micron-level precision adjustment. Operators can control the force application process more delicately and avoid sudden pressure changes caused by unstable movement.
[0033] Preferred, such as Figures 1-3 As shown, a rotating disk 11 is fixedly installed on the end of the extrusion screw 7 away from the base 1. The surface of the rotating disk 11 is provided with anti-slip texture, and its diameter is more than a multiple of the diameter of the extrusion screw 7, so that the operator can apply force accurately.
[0034] In this embodiment, the anti-slip texture design solves the problem of slippage caused by traditional smooth handles. Even during long-term operation or when hands are oily, the anti-slip texture can still provide sufficient friction to ensure the operator's precise control of the extrusion screw 7.
[0035] The large-diameter rotating disc 11 provides mechanical advantages, allowing operators to generate a large axial force on the screw with less hand force. This not only reduces the labor intensity of operators but also improves the precision of force control, achieving the dual effects of saving effort and precision.
[0036] The addition of the rotating disk 11 makes the entire operation process more ergonomic. Operators can comfortably hold the rotating disk 11 to rotate it, avoiding the discomfort that may be caused by directly rotating the screw. This humanized design improves work efficiency and reduces operator fatigue.
[0037] Preferred, such as Figure 3 As shown, a high-precision pressure sensor is provided on the surface of the pressure head 8 that contacts the hard waveguide assembly. The pressure sensor is electrically connected to a digital display device on the base 1 to display the applied pressure value in real time.
[0038] In this embodiment, the introduction of a pressure sensor enables real-time monitoring and digital display of the debugging pressure. Operators can intuitively see the pressure value applied to the hard waveguide component, which completely changes the traditional debugging method that relies on experience and feel, and significantly improves the accuracy and consistency of debugging.
[0039] Digital display devices provide objective data for quality control, allowing different operators to perform operations based on the same pressure standards, thus eliminating product quality fluctuations caused by human factors.
[0040] The pressure feedback system can also prevent workpiece damage caused by excessive force. When the pressure approaches the material's tolerance limit, the operator can stop applying force in time to avoid irreversible deformation or damage to the hard waveguide assembly due to excessive pressure, thus reducing the scrap rate.
[0041] Preferred, such as Figures 1-2 As shown, the inner side of the clamping plate 2 is provided with a quick-replaceable adapter block. The adapter block is fixed to the clamping plate 2 by magnetic connection or pin connection. The shape of the adapter block matches the outer contour of different models of hard waveguide components.
[0042] In this embodiment, the replaceable adapter block design allows a single fixture to be used for multiple models of hard waveguide components. Different models of hard waveguide components only need to have their corresponding adapter blocks replaced, eliminating the need to equip each product with a dedicated fixture, which significantly reduces equipment costs and production preparation time.
[0043] The magnetic or pin-connection fixing method enables quick replacement of the adapter block, ensuring a firm fixation during operation and facilitating quick disassembly when needed, greatly improving the flexibility and changeover efficiency of the production line.
[0044] The precise matching between the adapter block and the outer contour of the hard waveguide assembly ensures stable clamping of the workpiece. The good contact surface avoids local stress concentration that may occur during clamping, protects the workpiece surface from damage, and provides uniform clamping force, creating ideal conditions for subsequent debugging.
[0045] Preferred, such as Figures 1-3 As shown, a linear guide rail structure is provided between the positioning disk 10 and the positioning groove 9 to ensure that the positioning disk 10 slides smoothly in the positioning groove 9, and the surface of the positioning disk 10 is hardened to improve wear resistance.
[0046] In this embodiment, the linear guide structure reduces motion resistance, making operation smoother and less strenuous. Operators can more easily adjust the position of the positioning plate 10, improving the efficiency and accuracy of debugging.
[0047] The hardening treatment of the positioning disk 10 surface significantly improves wear resistance. During long-term use, the hardened surface can resist wear, maintain its original accuracy and smoothness, extend the service life of key components, and reduce maintenance costs.
[0048] Preferred, such as Figures 1-3 As shown, the pressure head 8 adopts a replaceable design and is connected to the extrusion screw 7 via a threaded connection or quick-release structure. Various pressure heads 8 of different shapes and materials are available to meet the debugging needs of different hard waveguide components.
[0049] In this embodiment, the replaceable pressure head 8 design enables the fixture to cope with various special debugging scenarios. Pressure heads 8 of different shapes can adapt to different parts and different deformation modes of the hard waveguide assembly, while pressure heads 8 of different materials can avoid damage to the surface of specific workpieces, providing greater process flexibility.
[0050] The threaded connection or quick-release structure enables rapid replacement of the pressure head 8. When the pressure head 8 needs to be replaced, the operation is simple and quick and will not affect the production rhythm. It is especially suitable for multi-variety, small-batch production mode.
[0051] The selection of multiple indenters 8 optimizes the debugging effect. The softer indenter 8 material can protect the fragile workpiece surface, while the indenter 8 with a specific shape can be precisely targeted at certain special deformation modes. These options make the debugging process more accurate and effective, and further improve product quality.
[0052] The method of using the rigid waveguide assembly debugging fixture of this utility model is as follows: Select the appropriate adapter block according to the model of the hard waveguide component to be debugged, and install it on the inside of the clamping plate 2. The adapter block is fixed by magnetic connection or pin connection to ensure that it matches the outer contour of the workpiece. Check whether each moving part is flexible, especially whether the sliding of the positioning plate 10 in the positioning groove 9 and the sliding of the locking post 13 on the side wall of the clamping plate 2 are smooth. Place the rigid waveguide assembly between the two clamping plates 2, with its bend facing the extrusion assembly. Gently push the workpiece to make it fully fit with the adapter block, ensuring the correct position. Select the appropriate shape and material of the pressure head 8 as needed and install it to the end of the extrusion screw 7, ensuring a firm connection. Adjust the angle of the positioning rod 4 so that the pressure head 8 is aligned with the bend in the rigid waveguide assembly that needs to be adjusted. During this process, the locking post 13 slides along the side wall of the clamping plate 2 to form a stable triangular support. Observe the guide surface 15 to ensure that the movement trajectory of the sliding block 5 is correct and that the center of the arc of the guide surface 15 coincides with the center of the movement trajectory of the locking post 13.
[0053] Slowly rotate the rotating disk 11, pushing the pressure head 8 closer to the rigid waveguide assembly via the extrusion screw 7. Because the diameter of the rotating disk 11 is larger than the screw diameter and its surface has anti-slip texture, operation is effortless and precise. Observe the pressure value on the digital display device to control the applied force. After initial contact, continue to slowly increase the pressure, causing controllable plastic deformation at the bend of the rigid waveguide assembly. The smooth sliding of the positioning disk 10 within the positioning groove 9 ensures a stable force application process, avoiding sudden pressure changes.
[0054] According to the process requirements, control the pressure within the predetermined range and maintain it for an appropriate time to allow the deformation to stabilize. After releasing the pressure, remove the workpiece for dimensional and performance testing. If the requirements are not met, the above debugging process can be repeated for fine-tuning.
[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
