Description

Technical Field

[0001] This invention relates to the field of auxiliary tools for microwave component connector processing, and more specifically to a clamping fixture for microwave component connectors used in induction welding. Background Technology

[0002] With the continuous iteration and upgrading of wireless communication technology, high frequency bands, multiple antennas, and large capacity have become core development trends. The architecture of communication systems is also gradually evolving from the traditional fixed-beam antenna architecture to the high-precision and high-flexibility active phased array antenna architecture. Active phased array technology, relying on a massive number of independently adjustable antenna radiating elements, achieves excellent performance such as rapid beam pointing switching and flexible beam shaping, significantly improving the detection accuracy and communication capacity of wireless communication systems. It is now widely used in various high-end military and civilian communication equipment.

[0003] Driven by the rapid development of phased array technology, its core supporting multi-channel microwave components face stringent performance and structural design requirements. Miniaturization, lightweighting, high integration, and high reliability have become the core development directions for microwave components. To meet the needs of multi-channel signal transmission, highly integrated microwave components require a large number of connectors. Due to the limitations of the overall structural size, various connectors are generally characterized by their small size, large number, and dense arrangement, which greatly increases the difficulty of later maintenance and fault repair of the components.

[0004] Currently, the repair of microwave component connectors mostly uses induction soldering, which melts the solder through the electromagnetic heat effect generated by an induction coil, enabling the disassembly and replacement of the faulty connector. However, in actual repair operations, the densely packed connector structure leads to significant technical defects in the existing process: the connector body size and the spacing between adjacent connectors in microwave components are extremely small, much smaller than the minimum diameter of the induction coil that can be used for induction soldering; during the repair process, when the relatively large induction coil is in operation, it will generate heat radiation and heat conduction on the surrounding adjacent connectors, causing the solder of adjacent normal connectors to melt.

[0005] After the solder melts, adjacent connectors without fixed constraints are prone to positional displacement, resulting in a "jumping" phenomenon. This not only directly damages the original installation position accuracy of the connectors, causing the assembly consistency of the components to fail, but also leads to the failure of the connector sealing structure, causing quality problems such as the component's airtightness. This significantly increases the rework defect rate, reduces the operational reliability and service life of microwave components, and seriously restricts the efficient and high-quality rework of highly integrated microwave components.

[0006] In view of this, how to design an induction welding connector clamping fixture that can adapt to densely arranged connectors, effectively constrain connector displacement, and ensure repair quality in the existing induction rework process of highly integrated microwave component connectors is a technical problem that urgently needs to be solved by those skilled in the art. This fixture addresses the technical pain points of adjacent connectors being prone to thermal displacement and the difficulty in ensuring positional accuracy and airtightness in the existing induction rework process of highly integrated microwave component connectors. Summary of the Invention

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a clamping fixture for microwave component connectors in induction welding, which solves the problem that, during the current induction welding process for repairing faulty microwave component connectors, adjacent connectors without fixed constraints are prone to positional displacement after the solder melts.

[0008] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: In this invention, a clamping fixture for microwave component connectors in induction welding includes a clamping rod, a counterweight connecting rod, and a support frame; The pressure rod is connected to the counterweight connecting rod, and the counterweight connecting rod is connected to the support frame; The counterweight link is equipped with a counterweight block, which is used to provide clamping force for the pressure rod. The pressure rod is provided with a pressing boss. The diameter of the pressing boss is larger than the diameter of the connector housing and smaller than the diameter of the connector solder groove. The pressing boss is used to press the connector. The support frame is equipped with support feet, which are used to cooperate with the component to be processed to fix the tooling onto the component as a whole. The support frame is also provided with a cylindrical boss, which cooperates with the cylindrical groove of the counterweight connecting rod, so that the counterweight connecting rod can rotate relative to the support frame.

[0009] Furthermore, the pressure rod and the counterweight connecting rod are detachably connected; The pressure bar also includes a limiting boss and a positioning boss; The counterweight has a positioning groove, which is assembled with a positioning boss to limit the horizontal relative position between the counterweight and the counterweight connecting rod. The limiting boss cooperates with the spring buckle to limit the vertical relative position between the pressure rod and the counterweight connecting rod; When the limit is reached: the spring clip engages between the limit boss and the bottom of the counterweight block to limit the pressure rod in the vertical direction relative to the counterweight connecting rod.

[0010] Furthermore, the pressing boss, the limiting boss, and the positioning boss are arranged sequentially along the axial direction of the pressure rod, and are all integrally formed into the side wall of the pressure rod as protrusion structures.

[0011] Furthermore, the cylindrical boss and the cylindrical groove are fitted with a clearance and are arranged coaxially to form a rotating pair in which the counterweight connecting rod rotates relative to the support frame.

[0012] Furthermore, the support frame is also provided with a crossbar, which is located in the clamping groove formed by the support foot and is integrally formed with the support foot; The crossbar is a semi-cylinder, which is in line contact with the end face of the component to be processed. The arc-shaped end face of the semi-cylinder crossbar fits against the end face of the component to form a line contact support.

[0013] Furthermore, the pressure bar is made of bakelite board, the counterweight connecting rod is made of stainless steel, and the support frame is made of polytetrafluoroethylene.

[0014] (III) Beneficial Effects This invention provides a clamping fixture for microwave component connectors in induction welding. Compared with the prior art, it has the following advantages: By setting up a clamping fixture, and configuring the clamping fixture as a combination of a pressure rod, a counterweight connecting rod, and a support frame, the problem of adjacent connectors being prone to positional displacement after the solder melts during the current induction welding process for repairing faulty microwave component connectors is solved. This effectively constrains connector displacement and ensures repair quality. Furthermore, since the connectors may not be arranged on the same straight line, this solution uses a combination of rotation and translation to cover all points on the plane, satisfying the welding of connectors in most positions, and facilitating the application of clamping fixtures in induction welding of microwave component connectors.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0019] This application provides a clamping fixture for microwave component connectors in induction welding, which solves the problem that when induction welding is used to repair faulty microwave component connectors, adjacent connectors without fixed constraints are prone to positional displacement after the solder melts. This effectively constrains connector displacement and ensures repair quality.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example: like Figures 1-5 As shown, a clamping fixture for microwave component connectors in induction welding includes a clamping rod 100, a counterweight connecting rod 200, and a support frame 300. The pressure rod 100 is connected to the counterweight connecting rod 200, and the counterweight connecting rod 200 is connected to the support frame 300; The counterweight link 200 is provided with a counterweight block 201, which is used to provide a clamping force to the pressure rod 100. The pressure rod 100 is provided with a pressing boss 101. The diameter of the pressing boss 101 is larger than the diameter of the connector housing and smaller than the diameter of the connector solder groove. The pressing boss 101 is used to press the connector. The support frame 300 is provided with support feet 301, which are used to cooperate with the component to be processed to fix the tooling as a whole onto the component. The support frame is also provided with a cylindrical boss 302, which cooperates with the cylindrical groove 203 of the counterweight connecting rod 200, so that the counterweight connecting rod 200 can rotate relative to the support frame 300. It should be noted that the cylindrical boss 302 and the cylindrical groove 203 are clearance-fitted and coaxially arranged to form a rotating pair in which the counterweight connecting rod 200 rotates relative to the support frame 300.

[0022] By setting up a clamping fixture, and configuring the clamping fixture as a combination of a pressure rod 100, a counterweight connecting rod 200, and a support frame 300, the problem of easy positional displacement of adjacent connectors without fixed constraints after the solder melts during the current induction welding process for repairing faulty microwave component connectors is solved. This effectively constrains connector displacement and ensures repair quality.

[0023] Furthermore, since the connectors may not be arranged on the same straight line, this solution uses a combination of rotation and translation to cover all points on the plane, satisfying the welding of connectors in most positions, and facilitating the application of clamping fixtures in induction welding of microwave component connectors.

[0024] like Figures 1-3 As shown, in one embodiment, the pressure rod 100 is detachably connected to the counterweight connecting rod 200; The pressure rod 100 also includes a limiting boss 102 and a positioning boss 103; The counterweight 201 has a positioning groove 202, which is assembled with the positioning boss 103 to limit the horizontal relative position between the counterweight and the counterweight connecting rod. The limiting boss 102 cooperates with the spring buckle to limit the vertical relative position between the pressure rod 100 and the counterweight connecting rod 200; When the limit is reached: the spring clip engages between the limit boss 102 and the bottom of the counterweight block 201, so that the pressure rod 100 is limited in the vertical direction relative to the counterweight connecting rod 200.

[0025] It should be noted that, under conventional design, the distance between the connector clamping surface and the tooling mounting surface has a fixed standard, and welding requirements can be met by replacing the clamping rods of different lengths. In actual use, the two lengths of clamping rods can meet the welding requirements of more than 95% of connectors. Therefore, for connector welding, matching welding tooling can be selected for different models, just like a screwdriver, and can be used as needed.

[0026] This solution features a detachable connection between the pressure rod 100 and the counterweight connecting rod 200, which is easy to install and remove. This allows for easy replacement of the pressure rod 100 with one that is compatible with the corresponding connector model, enabling the connector to be clamped during induction welding and ensuring better rework operations.

[0027] It should be noted that the pressing boss 101, the limiting boss 102 and the positioning boss 103 are arranged sequentially along the axial direction of the pressure rod 100, and are all integrally formed on the side wall of the pressure rod 100, which facilitates the processing and design of the pressure rod 100, the pressing boss 101, the limiting boss 102 and the positioning boss 103. The pressure bar 100 can be made of non-metallic materials in the prior art, and the counterweight 200 can be made of metallic materials in the prior art. All materials selected in this solution are existing materials.

[0028] In practical applications, the counterweight 201 can be detachably assembled onto the counterweight connecting rod 200, and the positioning groove 202 is opened on the side wall of the counterweight 201 and communicates with the corresponding hole used for inserting the counterweight 201. The pressure bar 100 is made of bakelite board, the counterweight connecting rod 200 is made of stainless steel, and the support frame 300 is made of polytetrafluoroethylene. All the materials used are readily available and will not be described in detail here.

[0029] like Figure 1 and Figure 4 As shown, specifically, the support frame is also provided with a crossbar 303, which is disposed in the clamping groove formed by the support foot 301 and is integrally formed with the support foot 301. The crossbar 303 is a semi-cylinder, which is in line contact with the end face of the component to be processed. The arc-shaped end face of the semi-cylinder crossbar fits against the end face of the component to form a line contact support. This reduces the support stability of the support frame 300, allows the weight of the counterweight 301 to act fully on the pressure bar 100, strengthens the clamping of the connector by the clamping fixture, and ensures the stability of the connector in the induction welding process.

[0030] The specific process of clamping the connector with the clamping fixture is as follows: First, the pressure rod 100 is made of bakelite board and is inserted from top to bottom into the corresponding hole on the stainless steel counterweight connecting rod 200, so that the positioning boss 103 is completely embedded in the positioning groove 202. Next, the spring clip is placed on the cylindrical rod position between the limiting boss 102 and the lower end face of the counterweight block 201 to fix the relative position between the pressure rod 100 and the counterweight connecting rod 200. Then, the counterweight connecting rod 200 and the support frame 300 made of polytetrafluoroethylene are combined by assembling the cylindrical groove 203 and the cylindrical boss 302. Finally, the support foot 301 is fixed to the component assembly to achieve tooling fixation on the component. While moving the support foot 301, the counterweight connecting rod 200 is rotated so that the pressure rod 100 is aligned with the connector to be pressed and pressed. After welding is completed, the operation of moving the support foot 301 and rotating the counterweight connecting rod 200 is repeated so that the pressure rod 100 is aligned with the next connector and the pressing required for subsequent welding is completed, saving the time of disassembling and assembling the clamping tooling.

[0031] In summary, compared with existing technologies, it has the following beneficial effects: 1. By setting up a clamping fixture, and configuring the clamping fixture as a combination of a pressure rod 100, a counterweight connecting rod 200, and a support frame 300, the problem of easy positional displacement of adjacent connectors without fixed constraints after the solder melts during the current induction welding process for repairing faulty microwave component connectors is solved. This effectively constrains connector displacement and ensures repair quality.

[0032] Furthermore, since the connectors may not be arranged on the same straight line, this solution uses a combination of rotation and translation to cover all points on the plane, satisfying the welding of connectors in most positions, and facilitating the application of clamping fixtures in induction welding of microwave component connectors.

[0033] 2. This solution features a detachable connection between the pressure rod 100 and the counterweight connecting rod 200, which is easy to install and remove. This allows for easy replacement of the pressure rod 100 with one that is compatible with the corresponding connector model, enabling the connector to be clamped during induction welding and ensuring better rework operations.

[0034] 3. By setting a crossbar 303 and setting the crossbar 303 as a semi-cylinder, the arc side end face of the semi-cylinder crossbar fits with the end face of the component to form a line contact support; in order to reduce the support stability of the support frame 300, so that the weight of the counterweight block 301 can be fully applied to the pressure rod 100, strengthen the clamping of the clamping fixture on the connector, and ensure the stability of the connector in the induction welding process.
