[0003] Existing RF probe testing equipment is inconvenient for automatically clamping and positioning circuit boards during use, making manual clamping and positioning cumbersome, time-consuming, and labor-intensive, thus reducing the efficiency of testing work. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a universal automatic testing device for radio frequency probes, which has advantages such as easy automatic clamping and solves the problem of cumbersome operation caused by manual clamping.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a universal automatic testing device for radio frequency probes, comprising a support base, a fixed frame fixedly connected to the top of the support base, a hydraulic cylinder fixedly connected to the top of the fixed frame, a movable plate fixedly connected to the bottom of the piston rod of the hydraulic cylinder, a radio frequency probe fixedly connected to the bottom of the movable plate, a connecting groove formed in the inner wall of the fixed frame, a slider disposed on one side of the movable plate passing through the connecting groove and fixedly connected to a support shaft, a movable rod movably connected to the outer wall of the support shaft, a through groove formed at the bottom of the movable rod, a guide shaft movably connected to the inner wall of the through groove, a movable rack fixedly connected to the outer wall of the guide shaft, a cylindrical gear movably connected to the top of one end of the movable rack extending into the support base, a movable lead screw fixedly connected to the inner wall of the cylindrical gear, a slider movably sleeved on the outer wall of the movable lead screw, and a positioning block fixedly connected to the top of the slider.
[0006] Furthermore, the inner wall of the support base is provided with a sliding groove, and the movable rack is slidably connected to the support base through the sliding groove, which facilitates the guiding of the movable rack and ensures that the movable rack can slide effectively in a straight line.
[0007] Furthermore, the top of the support base is provided with a guide groove, and the two ends of the movable lead screw are rotatably connected to the inner wall of the guide groove through bearings. The slider is slidably connected to the support base through the guide groove, which facilitates the guiding of the slider and avoids the slider from rotating.
[0008] Furthermore, the guide shaft is connected to the movable rod through a through groove, and the end of the movable rack near the guide shaft is arranged in a "U" shape, which facilitates the sliding of the movable rack through the guide shaft when the movable rod rotates.
[0009] Furthermore, both ends of the movable lead screw are provided with threads, and the threads at both ends of the movable lead screw are distributed in opposite directions. The sliders are symmetrically distributed at both ends of the movable lead screw, and the sliders are connected to the movable lead screw through threads, thereby facilitating the movement of the two sliders in opposite directions.

This effectively improves the convenience of operation and solves the problem of cumbersome operation caused by manual clamping and positioning. Attached Figure Description

[0017] 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.
[0018] Please see Figures 1-4 This embodiment of a general-purpose automatic testing device for radio frequency probes includes a support base 1, a fixed frame 2 fixedly connected to the top of the support base 1, a hydraulic cylinder 3 fixedly connected to the top of the fixed frame 2, a movable plate 4 fixedly connected to the bottom of the piston rod of the hydraulic cylinder 3, a radio frequency probe 5 fixedly connected to the bottom of the movable plate 4, a connecting groove 6 formed on the inner wall of the fixed frame 2, a slider on one side of the movable plate 4 passing through the connecting groove 6 and fixedly connected to a support shaft 7, a movable rod 8 movably connected to the outer wall of the support shaft 7, a through groove 9 formed at the bottom of the movable rod 8, a guide shaft 10 movably connected to the inner wall of the through groove 9, a movable rack 11 fixedly connected to the outer wall of the guide shaft 10, a cylindrical gear 12 movably connected to the top of one end of the movable rack 11 that extends into the support base 1, a movable lead screw 13 fixedly connected to the inner wall of the cylindrical gear 12, a slider 14 movably sleeved on the outer wall of the movable lead screw 13, and a positioning block 15 fixedly connected to the top of the slider 14.
[0019] Furthermore, the inner wall of the support base 1 is provided with a sliding groove, and the movable rack 11 is slidably connected to the support base 1 through the sliding groove, which facilitates the guiding work of the movable rack 11 and ensures that the movable rack 11 can effectively slide in a straight line.
[0020] Furthermore, the top of the support base 1 is provided with a guide groove, and the two ends of the movable lead screw 13 are rotatably connected to the inner wall of the guide groove through bearings. The slider 14 is slidably connected to the support base 1 through the guide groove, which facilitates the guiding of the slider 14 and avoids the slider 14 from rotating.
[0021] Furthermore, the guide shaft 10 is connected to the movable rod 8 through the through groove 9, and the movable rack 11 is arranged in a "U" shape at the end near the guide shaft 10, which facilitates the sliding of the movable rack 11 through the guide shaft 10 when the movable rod 8 rotates.
[0022] Furthermore, both ends of the movable lead screw 13 are threaded, and the threads at both ends of the movable lead screw 13 are distributed in opposite directions. The sliders 14 are symmetrically distributed at both ends of the movable lead screw 13, and the sliders 14 are connected to the movable lead screw 13 through threads, which facilitates driving the two sliders 14 to slide in opposite directions or in opposite directions.
[0023] The working principle of the above embodiments is as follows:
[0024] In use, the hydraulic cylinder 3 is first activated, causing the hydraulic cylinder 3 to drive the RF probe 5 to descend via the movable plate 4. As the movable plate 4 descends, it drives the movable rod 8 to rotate via the support shaft 7. This causes the movable rod 8 to slide via the through groove 9, which in turn drives the guide shaft 10 to slide. The guide shaft 10 then drives the movable rack 11 to slide, which in turn drives the cylindrical gear 12 to rotate. The cylindrical gear 12 then drives the movable lead screw 13 to rotate, which in turn drives the two sliders 14 to slide towards each other. This causes the two sliders 14 to drive the positioning block 15 to slide towards each other, automatically clamping the circuit board. This effectively improves the convenience of operation and solves the problem of cumbersome operation caused by manual clamping. At the same time, after the RF probe 5 descends, it will perform testing on the clamped circuit board.
[0025] After the test is completed, the hydraulic cylinder 3 drives the RF probe 5 to rise through the movable plate 4. Through the above principle, the movable rod 8 drives the movable rack 11 to reset and slide, which in turn drives the cylindrical gear 12 to reset and rotate. The cylindrical gear 12 then drives the movable lead screw 13 to reset and rotate, which in turn drives the movable lead screw 13 to reset and rotate through the slider 14. This causes the movable lead screw 13 to drive the two positioning blocks 15 to slide in opposite directions, thereby automatically releasing the positioning blocks 15 from the circuit board and facilitating the unloading of the positioning blocks 15.
