[0009] In one specific implementation, the bottom of the seat plate is provided with a second sliding groove, and the bottom of the limiting plate is provided with a second slider that slides in cooperation with the second sliding groove.

[0010] In one specific implementation, one end of the top rod is provided with a threaded hole, and the threaded hole is detachably fixed to the upright plate by a fixing bolt.

[0018] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0019] Please see Figures 1-5 This application provides an assembly structure for a radio frequency coaxial relay, including a base 1, a cylinder 2, a limit support assembly 3, a stamping assembly 4, and a material ejection assembly 5.

[0020] Cylinder 2 is mounted on one side of the base frame 1, and limiting support assembly 3 is mounted on the other side of the base frame 1. The stamping assembly 4 includes a movable seat 41, a stamping tube 42, and an end sleeve 43. The stamping tube 42 is fixed through and to the side of the movable seat 41. The end sleeve 43 is coaxially disposed at the end of the stamping tube 42, and both the end sleeve 43 and the end of the stamping tube 42 away from the end sleeve 43 are provided with guide grooves 44. Cylinder 2 drives the movable seat 41 to slide back and forth above the base frame 1, and the output rod end of cylinder 2 is fixedly connected to the movable seat 41. The unloading assembly 5 includes a vertical plate 51 and a push rod 52. The vertical plate 51 is fixed to the top of the base frame 1 at the end away from the limiting support assembly 3, and the push rod 52 is fixed to the side of the vertical plate 51 near the movable seat 41, and the push rod 52 is coaxially engaged with the stamping tube 42.

[0021] One end of the stationary contact, fitted with a stationary contact seat, is inserted into the stamping tube 42. Guided by the guide groove 44 in the end sleeve 43 of the stamping tube 42, the stationary contact can be inserted into the stamping tube 42 more accurately and quickly. The output rod of cylinder 2 pushes the movable seat 41 to move above the base 1. The moving movable seat 41 drives the stamping tube 42 and the stationary contact assembly installed at the end of the stamping tube 42 to move to the limit support assembly 3, realizing the rapid and accurate installation of the stationary contact assembly. After installation, cylinder 2 drives the movable seat 41 and the stamping tube 42 to move back to reset. During the retraction of the stamping tube 42, if the end of the stationary contact assembly is still inside the stamping tube 42 and cannot be removed by itself, the retracting stamping tube 42 gradually fits over the outside of the stamping tube 42, that is, the push rod 52 is inserted into the retracting stamping tube 42, pushing out the stationary contact assembly that is stuck inside the stamping tube 42 and completing the automatic unloading. That is, after the stationary contact assembly of the radio frequency coaxial relay is precisely installed by stamping, if the end of the stationary contact in the stationary contact assembly is still inside the stamping tube 42, the material can be automatically ejected through the cooperation of the push rod 52 during the process of the movable seat 41 moving back to reset, without manual intervention, thus improving the efficiency of workpiece assembly and processing.

[0022] In the above specific embodiment, the limiting support assembly 3 includes an L-shaped base plate 31, a limiting plate 32, and an elastic support part 33. The base plate 31 is fixedly installed with the seat frame 1, the limiting plate 32 is slidably installed with the base plate 31, and the elastic support part 33 connects the base plate 31 and the limiting plate 32. The elastic support part 33 includes a spring 331 and a guide rod 332. One end of the guide rod 332 slides through the side of the base plate 31 and is fixedly installed with the limiting plate 32. The spring 331 is sleeved on the outside of the guide rod 332 located between the limiting plate 32 and the base plate 31. When the movable seat 41 drives the stationary contact assembly to move toward the limiting support assembly 3, the spring 331 in the elastic support part 33 provides a certain buffering protection when the stationary contact assembly contacts the limiting plate 32, preventing excessive rigid compression that could damage the component, thus effectively reducing the component damage rate during stamping installation. A limiting block is provided at the end of the guide rod 332 to limit the installation of the spring 331.

[0023] In a specific configuration, a second sliding groove 34 is provided at the bottom of the base plate 31, and a second slider 35 is provided at the bottom of the limiting plate 32 to slide in conjunction with the second sliding groove 34. The cooperation between the second sliding groove 34 and the second slider 35 improves the stability when the limiting plate 32 and the base plate 31 slide relative to each other.

[0024] Specifically, one end of the push rod 52 is provided with a threaded hole 54, which is detachably fixed to the upright plate 51 by a fixing bolt 53. The upper surface of the base frame 1 is provided with a first sliding groove 11, and the bottom of the movable seat 41 is fixed with a first slider 46 that slides in cooperation with the first sliding groove 11. The first sliding groove 11 and the first slider 46 are provided to improve the stability of the movable seat 41 when it moves. A fixing plate 45 is fixedly provided on the outside of the stamping tube 42, and the fixing plate 45 is fixedly connected to the movable seat 41. The fixing plate 45 and the stamping tube 42 can be integrally formed, and the fixing plate 45 and the movable seat 41 are fixed with bolts. According to actual production needs, when assembling and processing stationary contact assemblies of different sizes, push rods 52 and stamping tubes 42 of different sizes can be installed.

[0025] Furthermore, the upper surface of the seat frame 1 is provided with a slot, and the bottom of the upright plate 51 is fixedly installed in the slot and fixed to the seat frame 1. The upright plate 51 is inserted into the seat frame 1 through the slot and then fixed in the vertical direction by bolts, which can improve the stability of the upright plate 51 when it is subjected to impact.

[0026] It should be noted that the specific model and specifications of cylinder 2 need to be determined based on the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, and therefore will not be described in detail. The power supply and principle of cylinder 2 are clear to those skilled in the art, and will not be described in detail here.

[0027] The working principle of the assembly structure of this RF coaxial relay is as follows: In use, one end of the stationary contact, fitted with a stationary contact seat, is inserted into the stamping tube 42. Guided by the guide groove 44 in the end sleeve 43 of the stamping tube 42, the stationary contact can be inserted into the stamping tube 42 more accurately and quickly. The output rod of the cylinder 2 pushes the movable seat 41 to move above the base 1. The moving movable seat 41 drives the stamping tube 42 and the stationary contact assembly installed at the end of the stamping tube 42 to move to the limit support assembly 3, thereby achieving a quick and accurate installation of the stationary contact assembly. After installation, cylinder 2 drives movable seat 41 and stamping tube 42 to move back and reset. During the retraction of stamping tube 42, if the end of the stationary contact assembly is still inside the stamping tube 42 and cannot be removed by itself, the retracting stamping tube 42 gradually covers the outside of the stamping tube 42. That is, the push rod 52 is inserted into the retracting stamping tube 42, pushing out the stationary contact assembly that is inside the stamping tube 42 and cannot be removed, thus completing the automatic unloading.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
