Technical Field

[0001] This utility model relates to the field of riveting technology, and in particular to a hydraulic riveting mechanism for the outer conductor of an RF connector. Background Technology

[0002] Radio frequency connectors are core components for signal transmission in fields such as 5G communication and aerospace. The outer conductor riveting must ensure coaxiality and shielding integrity to maintain radio frequency performance.

[0003] However, existing riveting mechanisms suffer from poor clamping synchronization. Traditional single-end drive or mechanical stamping schemes are prone to asynchronous movement of the double riveting blocks, leading to outer conductor deflection, coaxiality deviation, impedance matching failure, and increased signal loss. To address these issues, a hydraulic riveting mechanism for the outer conductor of an RF connector is proposed. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 4 An embodiment of this utility model is provided: a hydraulic riveting mechanism for the outer conductor of an RF connector, including a working shell 1, which is designed as the basic frame and support structure of the entire mechanism. A cylinder 2 is fixedly connected to the outside of the working shell 1, which is designed as a power drive source. A push block 3 is fixedly connected to the drive end of the cylinder 2, which is designed as a connector and force transmission medium. The outside of the push block 3 is slidably connected to the outside of the working shell 1. A gear rack 4 is fixedly connected to the outside of the push block 3, which is designed as a driving rack. The outside of the gear rack 4 is slidably connected to the inside of the working shell 1. A gear shaft 5 is rotatably connected inside the working shell 1, which is designed as a motion conversion hub. The outside of the gear rack 4 is meshed with the outside of the gear shaft 5. A gear rack 6 is slidably connected inside the working shell 1, which is designed as a driven rack. The outside of the gear rack 6 is meshed with the outside of the gear shaft 5 and receives the motion transmitted by the gear shaft (5).

[0031] The working shell 1 has multiple sliding grooves 7 inside. The sliding grooves 7 are designed as guide grooves to provide precise linear motion trajectory constraints for gear rack 1 (4) and gear rack 2 (6). Riveting blocks 8 are fixedly connected to the outside of gear rack 1 (4) and gear rack 2 (6). The riveting blocks 8 are designed as actuators to directly act on the outer conductor of the RF connector. The external parts of the multiple riveting blocks 8 are slidably connected to the inside of the working shell 1. The working shell 1 has multiple bundled sliding grooves 9 inside. The bundled sliding grooves 9 are designed as guide grooves for the riveting blocks 8. The top of the working shell 1 is fixedly connected to a worktable 10. The worktable 10 is designed as a platform for placing and positioning workpieces. The external parts of the working shell 1 are slidably connected to an electric slide rail 11. The electric slide rail 11 is designed as a linear motion guide and load-bearing drive. The external parts of the multiple electric slide rails 11 are fixedly connected to the same base 12. The base 12 is designed as a basic support platform and installation reference. The external parts of the working shell 1 are slidably connected to the outside of the base 12.

[0032] Working Principle: The clamping principle of the hydraulic riveting mechanism for the outer conductor of this RF connector is based on the cylinder 2 as the power source, which drives the push block 3 to move linearly. The push block 3 synchronously drives the gear rack 4 to slide. The gear rack 4 meshes with the gear shaft 5 to rotate, which in turn drives the meshing gear rack 6 to slide in the opposite direction. Since the gear rack 4 and gear rack 6 are respectively fixed to the riveting block 8, when they move in opposite directions, the riveting block 8 moves towards the outer conductor or away from the workpiece synchronously along the guide groove 9. The guide groove 7 and the guide groove 9 are constrained by the trajectory to ensure the linear movement of the riveting block 8 and ensure the coaxiality of the outer conductor. The meshing characteristics of the gear transmission realize the complete synchronization of the displacement and speed of the two riveting blocks 8, and avoid the workpiece being deflected by force. In addition, the electric slide rail 11 and the base 12 support the multi-station flow of the working shell 1 and are suitable for automated production lines. The worktable 10 integrates a control module, which can preset the clamping pressure and stroke, or monitor the status in real time. This design, which combines "cylinder 2-drive → gear reversal → bidirectional synchronous clamping → guiding to ensure accuracy," provides stable workpiece positioning for subsequent hydraulic riveting with its high synchronization and strong adaptability, thus supporting the mechanical strength and electrical performance of the RF connector from a mechanical structure perspective.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
