[0032] The cyclic test assembly 3 includes a guide frame 31 and a test ball 33. The guide frame 31 is a U-shaped circular shape with a gradient from high to low. The outer side of the test ball 33 is slidably connected to the guide frame 31. The outer side of the guide frame 31 is fixedly connected to a guardrail 32. The inner rotation of one of the support plates 23 is connected to a driving sprocket 34. The driving end of the motor 5 extends through the support plate 23 to the inside and is fixedly connected to the driving sprocket 34. The inner rotation of the other support plate 23 is connected to a driven sprocket 35. The driving sprocket 34 and the driven sprocket 35 are connected to the driven sprocket 34. A chain 36 is provided on the outside of the sprocket 35. The inside of the chain 36 is meshed with the outside of the driving sprocket 34 and the driven sprocket 35. A hook 37 is fixedly connected to the outside of the chain 36. The top of the limit frame 22 is fixedly connected to the shell 38. Both sides of the inner wall of the shell 38 are fixedly connected to the guide plates 39. The outer side of the test ball 33 is slidably connected to the guide plates 39. The inner wall of the shell 38 is fixedly connected to the end away from the support column 21 with a positioning plate 310. The guide frame 31 uses gravity to assist the test ball 33 to slide. The outer side of the guide frame 31 is fixedly connected to a guardrail 32, which is used to prevent the test ball 33 from escaping from the guide frame 31 during the sliding process, ensuring the safety of the test. The driving sprocket 34 is driven to rotate by the power of the motor 5, and the internal rotation of the other support plate 23 is connected to the driven sprocket 35, which cooperates with the driving sprocket 34 to transmit power through the chain 36. The inside of the chain 36 is meshed with the outer sides of the driving sprocket 34 and the driven sprocket 35 to ensure effective transmission of power. At this time, the hook 37 is used to fix and transmit the position of the test ball 33, ensuring that the test ball 33 maintains a certain force state when sliding on the guide frame 31. The shell 38 is used to protect the internal components and prevent external interference. The guide plate 39 is used to guide the sliding of the test ball 33, ensuring that the test ball 33 moves and slides stably along the specified route. The outer side of the test ball 33 is slidably connected to the guide plate 39, and accurate sliding testing is performed under the guidance of the guide plate 39. The positioning plate 310 is used to position the position of the shell 38 to maintain stability.

[0033] In the second embodiment, in order to prevent the test ball 33 from continuously bouncing on the surface of the diamond composite sheet, which leads to the problem of inaccurate test times, Figure 1 and Figure 4 As shown: In this solution, the pushing component 4 includes a mounting bracket 41, one side of the mounting bracket 41 is fixedly connected to the base plate 1, a pneumatic push rod 42 is installed on the top of the mounting bracket 41, and a switch sensor 43 is installed inside the shell 38.

Then the system can automatically adjust the pushing force to avoid the test ball 33 from bouncing continuously, thereby ensuring the accuracy of the test times and the reliability of the data.

[0034] Working principle:

[0035] like Figure 1 - Figure 4 As shown:

[0036] During use: First, the test ball 33 is placed on the guide frame 31 and slides along the U-shaped track of the guide frame 31 with the help of gravity. The gradual shape of the guide frame 31 ensures that the test ball 33 maintains a stable force state during the sliding process. At the same time, the guardrail 32 prevents the test ball 33 from escaping from the guide frame 31, ensuring the safety of the test. Then the motor 5 starts and provides power to drive the driving sprocket 34 to rotate. The rotation of the driving sprocket 34 engages with the driven sprocket 35 through the chain 36, thereby driving the driven sprocket 35 to rotate. The rotation of the driven sprocket 35 further drives the movement of the hook 37, and the hook 37 is fixed. And transmit the position of the test ball 33. At this time, the positioning plate 310 on the support plate 23 is used to keep the position of the shell 38 stable. The guide plate 39 guides the sliding of the test ball 33 to ensure that it moves stably along the specified route. Then, when the test ball 33 slides to the surface of the diamond composite sheet, the switch sensor 43 inside the limit frame 22 monitors the pressure applied by the test ball 33 on the surface of the diamond composite sheet in real time. When the ball is sensed, the pneumatic push rod 42 is started, and the system can automatically push the test ball to avoid the test ball 33 from bouncing continuously. At this time, the test ball 33 is pushed onto the guide frame 31 to realize a closed loop.

However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
