[0048] In some embodiments of the present invention, referring to Figure 3 and Figure 8 , the vacuum chamber 10 is cylindrical, the first direction is parallel to the axial direction of the vacuum chamber 10, and the vibration member 60 includes rolling members 66. The rolling members 66 are provided on opposite sides of the first platform 63 and are in contact with the inner wall of the vacuum chamber 10.

[0049] For easy understanding, the "axial direction" can refer to Figure 1 the left - right direction of

[0050] The rolling member 66 can be a structural member that can roll on the inner wall of the vacuum chamber 10. The number of rolling members 66 can be, but is not limited to, two, three, four, five, six, etc. The rolling member 66 can be, but is not limited to, a roller, a roller shaft, etc. Optionally, the rolling member 66 is a roller.

[0051] In the above technical solution, the inner wall of the cylindrical vacuum chamber 10 is a continuous arc surface. The rolling members 66 on both sides of the first platform 63 are symmetrically in contact with the inner wall, evenly dispersing the centrifugal force generated by the rotational motion to the inner wall of the vacuum chamber 10, avoiding the inclination or jamming of the first platform 63 due to uneven force, improving the stability of the first platform 63 rotating and vibrating around the first direction, and further improving the reliability of the test device 100.

[0052] In some embodiments of the present invention, referring to Figure 4 and Figure 6 , the vibrating member 64 can include: a motor 641, a driving wheel 642, a driven wheel 643, and a cam 644. The motor 641 is provided on the first platform 63; the driving wheel 642 is connected to the motor shaft 6411 of the motor 641; the driven wheel 643 is pivotally provided on the first platform 63 and meshes with the driving wheel 642; the cam 644 is connected to the driven wheel 643 and drives the second platform 65 to reciprocate in the second direction.

[0053] In the above technical solution, the motor 641 drives the driving wheel 642 to rotate, and the driving wheel 642 drives the cam 644 to move through the driven wheel 643. Due to the eccentric structure design of the cam 644, the cam 644 can drive the second platform 65 to reciprocate in the second direction during rotation, thereby realizing the vibration of the second platform 65 relative to the first platform 63. It can be understood that the vibration member 64 includes a structure of the motor 641, the driving wheel 642, the driven wheel 643, and the cam 644. The composition structure of this vibration member 64 is simple, which can improve the stability of the vibration member 64 and further improve the reliability of the test device 100.

[0054] In some embodiments of the present invention, referring to Figure 6 and Figure 7 , an avoidance groove 63a is provided at a position on the first platform 63 close to the driven wheel 643 and the cam 644.

[0055] The area of the avoidance groove 63a on the first platform 63 can cover the projected areas of the driven wheel 643 and the cam 644 on the first platform 63, and the avoidance groove 63a can penetrate the first platform 63.

[0056] In the above technical solution, an avoidance groove 63a is provided at a position on the first platform 63 close to the driven wheel 643 and the cam 644. Thus, the driven wheel 643 and the cam 644 can be partially located in the avoidance groove 63a, which can reduce the height of the driven wheel 643 and the cam 644 in the direction from the first platform 63 to the second platform 65, make the structure of the vibration member 60 more compact, can reduce the volume of the vibration member 60, and further reduce the volume of the vacuum chamber 10, which is convenient for transportation and installation. At the same time, it can also save materials and reduce costs.

[0057] In some embodiments of the present invention, referring to Figure 6 and Figure 7 , the cam 644 is provided with a guide groove 644a, the guide groove 644a extends along the circumferential edge contour of the cam 644, a push rod 651 is provided on one side of the second platform 65 close to the first platform 63, the push rod 651 is provided with a first roller 6511, and the first roller 6511 is arranged in the guide groove 644a and abuts against the bottom groove wall 6441 of the guide groove 644a.

[0058] In the above technical solution, the guide groove 644a extends along the circumferential edge profile of the cam 644. After the first roller 6511 of the ejector rod 651 is embedded in the guide groove 644a, its movement trajectory is completely determined by the profile of the cam 644, which has a guiding effect and can ensure the accuracy of the vibration trajectory. The bottom groove wall 6441 of the guide groove 644a abuts, and the two side walls of the guide groove 644a laterally limit the roller, preventing the ejector rod 651 from shifting in the axial direction during vibration, and can ensure the stability of the vibration trajectory. Secondly, the ejector rod 651 realizes rolling contact with the guide groove 644a through the first roller 6511, which can reduce the wear of the ejector rod 651 and the cam 644, improve the long-term stability of vibration, and extend the service life of the entire vibrating part 64. Using rolling friction also helps to reduce the waste chip pollution generated by wear to the test piece 200.

[0059] In some embodiments of the present invention, referring to Figure 6 and Figure 7 , second rollers 6512 are provided at both ends of the ejector rod 651 in the axial direction of the cam 644, and the second rollers 6512 abut against the surface of the cam 644.

[0060] It can be understood that both ends of the second roller 6512 can contact the inner and outer ends of the cam 644.

[0061] In the above technical solution, the second roller 6512 abuts against the surface of the cam 644, and the movement trajectories of the second roller 6512 and the first roller 6511 are similar. This can increase the support surface between the cam 644 and the ejector rod 651, improve the support stability of the cam 644 for the ejector rod 651, and further improve the stability of the second platform 65 relative to the first platform 63 during vibration, which can improve the stability of the vibration trajectory and further improve the reliability of vibration.

[0062] In some embodiments of the present invention, referring to Figures 4 to 7 , the first platform 63 is provided with a limiting component 631, and the limiting component 631 is provided on both opposite sides of the first platform 63 where the vibrating part 64 is located; the limiting component 631 includes a limiting rod 6311 and a damping component 6312. The limiting rod 6311 is provided on the first platform 63 and is slidably matched with the second platform 65 in the second direction. The damping component 6312 is sleeved on the limiting rod 6311 and abuts against the first platform 63 and the second platform 65.

[0063] The limiting rod 6311 can be a mechanism that limits the distance between the first platform 63 of the second platform 65, and can be, but is not limited to, a cylindrical straight rod, a stepped shaft, a spline shaft, an air floating shaft, etc.

[0065] In the above technical solution, the limiting rod 6311 is slidably engaged with the second platform 65 along the second direction, providing a rigid guiding path for it, restricting the displacement of the second platform 65 in the non-vibration direction, ensuring that the vibrating member 64 moves only along the predetermined direction, avoiding jamming of the vibrating component 60 or test errors caused by deviation, and improving the reliability of vibration.

The shock-absorbing component 6312 can undergo elastic deformation when the second platform 65 vibrates, converting the vibration energy into heat energy or elastic potential energy, thereby playing a buffering role, being beneficial to reducing the impact force between the ejector rod 651 and the cam 644, and improving the reliability of the test device 100.
