[0025] Embodiment 1

[0026] Combined with Figures 1 to 4 , an integrated circuit board load test device includes a frame 1, a hydraulic push rod 2 is fixedly connected to the top of the frame 1, a test assembly 3 is fixedly connected to the bottom end of the hydraulic push rod 2, a clamping mechanism 4 is arranged on the top of the frame 1, and installation mechanisms 5 are arranged on both sides of the clamping mechanism 4.

[0027] The clamping mechanism 4 includes a connecting frame 408. The connecting frame 408 is fixedly connected to the top of the frame 1. A fixing plate 401 is fixedly connected to the front of the connecting frame 408. A motor 402 is fixedly connected to the top of the fixing plate 401. A worm 403 is fixedly connected to the back of the motor 402. A worm gear 404 is threadedly connected to the outer wall of the worm 403. A threaded rod 405 is fixedly connected to the inner ring of the worm gear 404. A threaded block 406 is threadedly connected to the outer wall of the threaded rod 405. A connecting block 407 is fixedly connected to one side of the threaded block 406. A clamping block 409 is fixedly connected to the side of the connecting block 407 away from the threaded block 406.

[0028] Further, a rotating hole is formed in the front of the connecting frame 408. The outer wall of the worm 403 is rotatably connected to the inner wall of the rotating hole. The rear end of the worm 403 is rotatably connected to the back inner wall of the connecting frame 408, which is convenient for supporting the worm 403 so that it can rotate stably.

[0029] Further, the threaded rod 405 is rotatably connected to the inner wall of the connecting frame 408. The thread shapes on the outer walls at both ends of the connecting frame 408 are opposite, which is convenient for converting the rotational movement of the threaded rod 405 into the linear movement of the threaded block 406.

[0030] Further, four threaded blocks 406 are provided. The four threaded blocks 406 are all slidably connected to the inner wall of the connecting frame 408, which is convenient for limiting the threaded block 406 during its movement.

[0031] Further, a moving port adapted to the connecting block 407 is formed inside the connecting frame 408. The connecting block 407 passes through the inside of the connecting frame 408 through the formed moving port, which is convenient for the threaded block 406 to drive the clamping block 409 to clamp the integrated circuit board during its movement.

[0032] Embodiment Two

[0033] Refer to Figures 1 to 3 , and on the basis of Embodiment One, it is further obtained that the installation mechanism 5 includes a fixing block 501. The fixing block 501 is fixedly connected to the top of the frame 1. A sliding groove 502 is formed inside the fixing block 501. A sliding block 503 is slidably connected inside the sliding groove 502. A bolt 504 is provided on the outside of the fixing block 501, which is convenient for better installation and disassembly of the clamping mechanism 4.

[0034] Further, the shape of the sliding block 503 is adapted to the shape of the sliding groove 502. The outer wall of the bolt 504 is threadedly connected to one side of the fixing block 501 and the inside of the sliding block 503 respectively, which is convenient for the bolt 504 to limit the sliding block 503.

[0035] During the actual operation process, when this device is in use, first, the staff can place the integrated circuit board to be tested inside the two clamping blocks 409. Then, start the motor 402 to work. The output end of the motor 402 drives the worm 403, the worm gear 404, and the threaded rod 405 to rotate in sequence, so that the rotational motion of the threaded rod 405 can be converted into the linear motion of the threaded block 406. Since the external threads at both ends of the threaded rod 405 are opposite, the two clamping blocks 409 will approach each other to firmly clamp the integrated circuit board, making it more stable during the testing process. After the clamping work is completed, the staff can start the hydraulic push rod 2 to work. The hydraulic push rod 2 drives the test component 3 to descend to test the integrated circuit board, thereby achieving the purpose of testing the load performance.

[0036] Slide the slider 503 into the inside of the chute 502. Then, screw the bolt 504 into the fixing block 501 and the slider 503 to complete the installation of the clamping mechanism 4. Similarly, it can also be disassembled, enhancing the flexibility of the device and not consuming much time during installation and disassembly.

[0037] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the said element.
