[0002] As an important electrical equipment, the network control cabinet contains many sophisticated electronic components and mechanical parts. During transportation and installation, the control cabinet may be affected by various vibrations and shocks, which may damage the internal structure of the control cabinet and affect its normal operation. Therefore, vibration testing can simulate the vibration conditions in the actual working environment and evaluate the vibration resistance and structural stability of the control cabinet, thereby ensuring its stable operation under various working conditions.

[0003] At present, in the process of testing the internal structure of a network control cabinet and the stability of connecting lines, the network control cabinet is generally placed on a support plate, and then the lateral reciprocating motion of the network control cabinet is realized through a lateral motion mechanism to simulate the lateral vibration of the network control cabinet, and then the vertical reciprocating motion of the network control cabinet is realized through a vertical motion mechanism to simulate the vertical vibration of the network control cabinet, so as to realize the test of the network control cabinet. However, this method requires setting and adjusting the parameters of the two mechanisms separately to simulate vibrations in different directions, which may increase the test preparation time and the test cycle and reduce the test efficiency. In view of this, we propose a test device for a network control cabinet. Summary of the invention

The upper side of the slide 2 is hinged with a hinge rod 534, and one end of the hinge rod 534 away from the slide 2 is hinged to the lower side of the slide 2. The fixing block 532 is elastically connected to the slide 2 by a connecting spring. The slide 2 slides on the guide rod 531 through the slide 2, so that the slide 2 slides up and down in the recess of the body 1. The adjusting component 54 includes a disk 541, and a through groove 542 is provided on the outer wall of the disk 541. A threaded block 544 is slidably connected to the through groove 542, and a screw rod 543 is rotatably connected to the through groove 542. , and the screw rod 543 is threadedly connected with the thread block 544, the screw rod 543 is fixedly connected with the output shaft of the micro motor 545, the micro motor 545 is fixedly installed in the disc 541, and the thread block 544 is provided with two groups, one group of thread blocks 544 is fixedly connected with the rotating shaft 1 523, and the other group of thread blocks 544 is fixedly connected with the rotating shaft 2 525. When the rotating shaft 1 523 is driven to rotate by the output shaft of the stepping motor 522, the synchronous belt 524 drives the rotating shaft 2 525 to rotate, so that the thread block 544 drives the disc 541 to rotate, and the slider 533 is pressed by the connecting spring to the slider 533, so that the slider 533 abuts against the disc 541, and the rotation of the disc 541 is performed.

[0045] It should be noted that the above-mentioned electrical components are all existing technology products. Technical personnel in this field select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally.

Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The applicant does not make specific restrictions here.

[0046] When in use, the network control cabinet is first placed on the placement seat 3, and then the cylinder 42 is started. The output end of the cylinder 42 drives the movement of the positioning plate 43, so that the positioning plate 43 fixes the network control cabinet, and then the stepper motor 522 is started. When the output shaft of the stepper motor 522 drives the rotating shaft 1 523 to rotate, the synchronous belt 524 drives the rotating shaft 2 525 to rotate, so that the threaded block 544 drives the disk 541 to rotate, and the slider 533 is pressed by the connecting spring to make the slider 533 contact with the disk 541, thereby driving the slider 533 to slide on the guide rod 531, driving the hinge rod 534 to move, and making the slide plate 2 slide up and down in the recess of the body 1, realizing the up and down vibration of the simulated network control cabinet. In this process, the slider 533 slides on the guide rod 531, driving the hinge rod 72 to move, and then driving the swing rod 71 and the elastic sheet 73 to move, so that the protrusion 74 knocks and vibrates the bottom of the slide plate 2;

[0047] At the same time, the electric cylinder 51 is started, and the output end of the electric cylinder 51 rises, driving the long plate 521 to rise, and then the disc 541 and the round rod 552 to rise. After the round rod 552 rises, the telescopic end of the elastic telescopic rod 554 is aligned with the limit groove 555, and the telescopic end of the elastic telescopic rod 554 is inserted into the limit groove 555. When the round rod 552 continues to rotate, it drives the sleeve rod 551 to rotate, and then drives the cam 56 to rotate, so that the placement seat 3 slides on the slide plate 2, thereby realizing the left and right reciprocating motion of the network control cabinet;

[0048] At the same time, by starting the micro motor 545, the output shaft of the micro motor 545 rotates, driving the screw 543 to rotate. Since the position of the threaded block 544 is fixed, the screw 543 moves relative to the threaded block 544, causing the distance between the center of the disk 541 and the threaded block 544 to change, thereby adjusting the amplitude of the subsequent up and down movement of the slide plate 2, thereby simulating the network control cabinet being subjected to different vibration amplitudes.
