[0024] In an exemplary embodiment, Figure 1-4As shown, this embodiment provides a friction sensitivity testing device, which includes a mounting frame 1, and an upward push driver 3 fixedly installed at the lower end of the mounting frame 1, and a horizontal support plate 4 fixedly installed in the middle section of the mounting frame 1, and a slide 5 slidably arranged on the horizontal support plate 4, as well as a sample loading component and a striking component; the striking component includes an explosion capsule 6 fixedly connected to the mounting frame 1, and a striking rod 7 horizontally telescopically arranged with the explosion capsule 6, and the explosion capsule 6 is also provided with an entrance 8 located directly below it; a work station hole is provided at one end of the slide 5, and the sample loading component is clamped at the work station hole. As the slide 5 slides, the sample loading component can reciprocate between the upper part of the upward push driver 3 and the outside of the mounting frame 1, and can enter or exit the explosion capsule 6 under the drive of the upward push driver 3.

[0025] In the above embodiment, the sample loading assembly is used for loading the sample 10, and then placed on the slide 5, and enters with the slide 5 to the top of the push-up driver 3, and then is pushed up by the push-up driver 3 to enter the explosion chamber 6, and then the striking rod 7 is operated. After completion, the push-up driver 3 moves downward, and the sample loading assembly falls back onto the slide 5 with the downward movement, and then moves with the slide 5 to the outside of the mounting frame 1, and then the next round of sample loading is carried out, and then the next round of operation is carried out, and so on. During the process, the sample loading assembly does not need to be manually taken out and loaded, which solves the problem that the sample needs to be manually loaded and taken out in the prior art, so the efficiency is low;

[0026] Specifically, the sample loading component includes an outer sleeve 11 that can be accommodated in the work station hole, one end of the outer sleeve 11 is provided with a first outer support ring 12 that can abut against the outer edge of the upper end of the work station hole, an upper push rod 13 is also provided in the outer sleeve 11, and the upper push rod 13 also abuts against a lower slide column 14, and a slide column sleeve 15 is also provided around the lower slide column 14, and an upper slide column 16 with one end extending outside the slide column sleeve 15 and located above the lower slide column 14 is also provided in the slide column sleeve 15, the outer sleeve 11 and the upper push rod 13 can be driven by the push-up driver 3 to reciprocate up and down, so that the slide column sleeve 15 can be pushed into or out of the explosion chamber 6; the explosion chamber 6 is also fixedly connected with an upper push column 9, and the upper slide column 16 and parts of the lower slide column 14 can be pushed out of the slide column sleeve 15, and the upper slide column 16 can be with The upper push column 9 is abutted, and at this time, the striking rod 7 moves into the explosion chamber 6 and can hit the upper sliding column 16 to make the upper sliding column 16 translate relative to the lower sliding column 14, and the sample 10 is loaded between the lower sliding column 14 and the upper sliding column 16, and the striking rod 7 is knocked to move into the explosion chamber 6 to hit the upper sliding column 16, and the set sliding column sleeve 15 provides a barrier on the outside, so that the loading of the sample 10 can be carried out smoothly. After the sample loading assembly is pushed into the explosion chamber 6, the sample 10 continues to be pushed out to the top of the sliding column sleeve 15, and the upper sliding column 16 is abutted against the upper push column 9, so that the sample 10 is pressed tightly by the lower sliding column 14 and the upper sliding column 16 respectively. In more detail, the upper push rod 13 is directly driven by the upward push driver 3, thereby indirectly pushing the lower sliding column 14.

[0027] like Figure 1-4As shown in the more detailed exemplary embodiment, a support sleeve 17 is further provided in the outer sleeve 11, and a second outer support ring 18 capable of abutting against the outer edge of the upper end of the outer sleeve 11 is further provided at one end of the support sleeve 17, and an annular platform is further provided in the support sleeve 17, and the upper push rod 13 is fixedly connected to the inner support ring 19 so that it is arranged in the support sleeve 17, and the lower end of the upper push rod 13 also extends to the bottom of the support sleeve 17, and the upper end is also fixedly connected to the lower push column 29, and the lower push column 14 abuts against the lower push column 29, and the support sleeve 17 is provided to provide upward support for the slide column sleeve 15 The support makes the sliding column sleeve 15 stable, and the second outer support ring 18 allows the sliding column sleeve 15 and the outer sliding sleeve 11 to be taken out of the work station hole or put into the work station hole together, and the inner support ring 19 prevents the upper push rod 13 from being disengaged from the support sleeve 17 from below, thereby preventing the lower sliding column 14 from being disengaged from the bottom of the support sleeve 17; in more detail, when loading the sample, the present scheme first takes out the upper sliding column 16, fills the sample 10, and then puts in the upper sliding column 16, and then sends the sample 10 to the mounting frame 1 through the slide 5, and continues the subsequent actions to start the operation.

[0028] like Figure 1-4 As shown, in a further detailed exemplary scheme, the test device also includes a downward pressure drive 2 fixedly mounted on the mounting frame 1, and the downward pressure drive 2 is connected to a push rod 31 located below it and telescopically moving in and out of the explosion chamber 6, and the positive projection of the end of the push rod 31 away from the downward pressure drive 2 can be located on the annular wall of the sliding column sleeve 15. The push rod 31 is set to move downward under the drive of the downward pressure drive 2, so as to push the sliding column sleeve 15 downward, ensuring that the sliding column sleeve 15 can smoothly exit the explosion chamber 6 downward after the upward push drive 3 moves downward. At the same time, when the test is carried out, the push rod 31 also moves downward under the action of the downward pressure drive 2 and pushes against the sliding column sleeve 15, so that the upper end of the sliding column sleeve 15 is stabilized to ensure smooth operation. After the operation of the striking rod 7 is completed, the upward push drive 3 moves downward, and the downward pressure drive 2 also moves downward, so that the sliding column sleeve 15, the upper sliding column 16, the lower sliding column 14 and other components can smoothly exit the explosion chamber 6;

[0029] Furthermore, a spring 20 is provided in the support sleeve 17, which is located above the inner support ring 19 and surrounds the outside of the lower top column 29. A supporting ring 21 is also provided above the spring 20. The sliding column sleeve 15 abuts against the supporting ring 21. The supporting ring 21 is directly abutted against the sliding column sleeve 15 and supported in the upper end of the support sleeve 17 after the spring 20. The spring 20 can assist in providing elastic pressure to make the supporting ring 21 and the sliding column sleeve 15 abut tightly. After the sample loading assembly enters the explosion chamber 6, the upper top column 9 abuts against the upper sliding column 16, and the push rod 31 moves downward under the action of the downward pressure driver 2 to make the sliding column sleeve 15 move downward, and indirectly compresses the spring 20 downward through the supporting ring 21. Finally, under the joint action of the spring 20 and the push rod 31, the upper sliding column 16, the sample 10 and part of the lower sliding column 14 are kept above the sliding column sleeve 15, thereby ensuring that the striking rod 7 can operate normally.

[0030] In a more detailed solution, the inner ring of the second outer support ring 18 extends into the upper end of the support sleeve 17, and the lower end of the support ring 21 is provided with a butt ring 30 that can abut against the lower ring wall of the second outer support ring 18, so that the spring 20 can make the butt ring 30 always abut against the second outer support ring 18, thereby indirectly making the sliding column sleeve 15, the lower sliding column 14 and the upper sliding column 16 more stable; further, a guide column 22 is fixedly connected between the lower push column 29 and the upper push rod 13, and the lower end of the spring 20 is sleeved outside the guide column 22, so that the spring 20 can run more smoothly in the vertical direction.

[0031] like Figure 1-4 As shown, in a further exemplary scheme, a through hole 23 is provided on the horizontal support plate 4 and is located directly below the work station hole. The push-up drive 3 is connected to a push column 24 and the push column 24 can move up and down through the through hole 23 and abut against the lower end of the upper push rod 13, that is, the output end of the push-up drive 3 is connected to the push column 24, and then indirectly pushes the upper push rod 13 to move.

[0032] like Figure 1-4 As shown, in a further exemplary scheme, a horizontal driver 25 is also fixedly connected to the horizontal pallet 4, and the horizontal driver 25 is connected to a horizontally movable mounting plate 26, and the horizontal pallet 4 is fixedly connected to the mounting plate 26, that is, the movement of the slide 5 is realized by the horizontal driver 25. Specifically, the horizontal driver 25 first drives the mounting plate 26, and then drives the slide 5 to move through the horizontal pallet 4. More specifically, the mounting plate 26 includes a mounting section 27 located above the horizontal driver 25 and slidably connected thereto, and a connecting section 28 fixedly connected to one end of the mounting section 27, the horizontal pallet 4 is fixedly connected to the mounting section 27, and the horizontal driver 25 has an output end fixedly connected to the connecting section 28, so that the horizontal driver 25, the horizontal pallet 4 and the slide 5 can have a smaller overall volume at the beginning, and the relative sliding between the horizontal pallet 4 and the horizontal driver 25 can also play a horizontal guide, thereby making the slide 5 move more smoothly.

[0033] In this solution, the downward pressing driver 2, the upward pushing driver 3 and the horizontal driver 25 can all be one or more telescopic drivers such as air cylinders and oil cylinders, and can be selected according to specific circumstances.
