[0024] The limiting assembly 2 includes a mounting platform 20, and a positioning block 21 is respectively installed on both sides of the upper end surface of the mounting platform 20, and the two positioning blocks 21 are arranged in parallel. A positive and negative threaded rod 22 is provided between the two positioning blocks 21, and a sliding block 23 is provided at the positive and negative teeth on the outer sides of the positive and negative threaded rod 22, respectively meshing and sliding with each other. A clamping plate 24 is installed on one side of the upper end surface of the two sliding blocks 23, and the two clamping plates 24 are arranged in opposite parallel directions. The upper end surface of the mounting platform 20 is equipped with two guide rails 25, and two chiseling blocks 26 are chiseled and slidably provided on the two guide rails 25. The upper end surfaces of the two adjacent chiseling blocks 26 on the same side are connected to the sliding block 23 on the same side;

[0025] A support plate 11 is respectively installed on both sides of the upper end surface of the base plate 1, and a screw seat 3 is installed on the upper end surface of one of the support plates 11. The screw seat 3 has a rectangular cavity and a first drive motor 31 is installed in the rectangular cavity. The output end of the first drive motor 31 is connected with a first threaded screw 32, and the first threaded screw 32 is externally engaged and slidably provided with a first slider 33. A second drive motor 4 is installed on one side of the first slider 33, and the output end of the second drive motor 4 is connected with a second threaded screw 41 and one end of the second threaded screw 41 passes through the first slider 33. The second threaded screw 41 is externally engaged and slidably provided with a second slider 42, and the upper end surface of the second slider 42 is equipped with a third drive motor 5, and the output end of the third drive motor 5 is connected with a third threaded screw 51 and the third threaded screw 51 is vertically arranged. The third threaded screw 51 is externally engaged and slidably provided with a positioning plate 52, and the positioning plate 52 is equipped with a mounting tube 6.

[0026] In this embodiment, by the mutual cooperation between the components in the limit assembly 2, the user can drive the two sliding blocks 23 to move in the center by rotating the positive and negative threaded rods 22, so that the limit cover is clamped and limited by the two clamping plates 24. The clamping force can be controlled by manually rotating the positive and negative threaded rods 22 to prevent damage to the limit cover. At the same time, clamping and limiting the limit cover can effectively prevent the cover from tipping over or sliding during the test, thereby ensuring the accuracy and comparability of the test results. The adjustability between the two clamping plates 24 allows the device to adapt to different sizes. The size and shape of the limit cover plate increases versatility. By controlling the first drive motor 31, the pressing rod 61 can be driven to move within the stroke range of the first threaded screw 32. By controlling the second drive motor 4, the pressing rod 61 can be driven to move within the stroke range of the second threaded screw 41. By controlling the third drive motor 5, the pressing rod 61 can be driven to slide radially within the stroke range of the third threaded screw 51, thereby performing pressure detection on the limit cover plate downward. It has high flexibility, can meet a variety of different test requirements, has strong adaptability, and can also improve the overall test efficiency and speed up the production process.

[0027] Specifically, refer to Figure 1-4 The mounting tube 6 has a sliding cavity and a pressing rod 61 is passed through the lower end surface of the mounting tube 6. The upper end of the pressing rod 61 is equipped with a sliding disk 611 and the sliding disk 611 is located in the sliding cavity of the mounting tube 6. The top wall of the sliding cavity of the mounting tube 6 is equipped with a pressure sensor 62, and the output end of the pressure sensor 62 is connected to the sliding disk 611.

[0028] In this embodiment, when the installation tube 6 is driven downward, the pressing rod 61 slidingly arranged in the installation tube 6 abuts against the limiting cover plate and applies pressure, so that the pressure sensor 62 connected to the sliding plate 611 detects the pressure.

[0029] Specifically, refer to Figure 1-2 A fixed block 27 is assembled on both sides of the upper end surface of the mounting platform 20. A sliding groove is opened in each of the two fixed blocks 27, and a slide 28 is slidably provided in the sliding groove. A rotating button 271 is passed through one side of the two fixed blocks 27, and one end of the rotating button 271 is tightly against one side of the slide 28.

[0030] In this embodiment, the support height of the slide 28 can be adjusted by rotating the rotating button 271 so that one end of the rotating button 271 no longer abuts against the slide 28. Conversely, by rotating the rotating button 271 so that one end of the rotating button 271 abuts tightly against the slide 28, the slide 28 can be limited and fixed.

[0031] Specifically, refer to Figure 1-3 The upper end surface of the other support plate 11 is equipped with a slide rail 12 , and a connecting block 13 is slidably engaged with the slide rail 12 , and one end of the second threaded screw 41 passes through the connecting block 13 .

[0032] In this embodiment, the slide rail 12 is provided with the assistance of the connecting block 13, so that the first sliding block 33 can be made more stable when moving.

[0033] Specifically, refer to Figure 1-3 Two first limiting rods 43 are assembled between the first slider 33 and the connecting block 13 , and both first limiting rods 43 pass through the second slider 42 .

[0034] In this embodiment, the two first limiting rods 43 are used to limit the second slider 42 so that the second slider 42 is more stable when moving.

[0035] Specifically, refer to Figure 1-3 The upper end surface of the second slider 42 is equipped with two second limiting rods 53. The two second limiting rods 53 both pass through the positioning plate 52 and are jointly equipped with a top plate at their upper ends.

[0036] In this embodiment, the two second limiting rods 53 are used to limit the positioning plate 52 so that the positioning plate 52 is more stable when moving. The top plates at the upper ends of the two second limiting rods 53 are used to upper limit the positioning plate 52.

[0037] The limit cover plate testing device of the utility model:

[0038] Step 1: In actual use, first connect the first drive motor 31, the second drive motor 4 and the third drive motor 5 to the external power supply, then place the limit cover plate to be detected on the upper end of the two slides 28, and adjust the support height of the slide 28 by rotating the rotating button 271 so that one end of the rotating button 271 is no longer in contact with the slide 28. Then, hold the handle on one side of the positive and negative threaded rod 22 and rotate the positive and negative threaded rod 22. When the positive and negative threaded rod 22 rotates, the two guide rails 25 cooperate with the four engaging blocks 26 to limit the two sliding blocks 23, so that the two sliding blocks 23 that are engaged and slidable at the positive and negative teeth outside the positive and negative threaded rod 22 are driven to move in the center, so that the limit cover plate is clamped and fixed by the two clamping plates 24.

[0039] Step 2: After the limit cover is clamped and fixed, the first drive motor 31 is controlled to drive the first threaded screw 32 to rotate, so that the first slider 33 can be driven to move within the stroke range of the first threaded screw 32. The second drive motor 4 is controlled to drive the second threaded screw 41 to rotate, so that the second slider 42 can be driven to move within the stroke range of the second threaded screw 41. The third drive motor 5 is controlled to drive the third threaded screw 51 connected to the output end to rotate, so that the mounting tube 6 can be driven downward, so that the pressing rod 61 is against the limit cover and applies pressure, so that the pressure sensor 62 connected to the sliding plate 611 detects the pressure.
