[0002] In many high-tech fields such as optical instrument manufacturing, aerospace, and communication technology, optical glass is a key material, and the stability and reliability of its performance are crucial. Especially in a vibration environment, the performance of optical glass directly affects the stability and accuracy of the entire system. Therefore, conducting vibration performance tests on optical glass to evaluate its stability and durability under different vibration conditions has become an essential part of product research and development and quality control.

[0003] In current vibration performance tests, the clamping device for optical glass plays a crucial role. However, traditional clamping devices often have many deficiencies in design. On the one hand, some clamping devices have complex structures and cumbersome operations, which not only increase the test preparation time but also easily cause damage to the optical glass due to improper operation. On the other hand, some clamping devices perform poorly in terms of clamping force and stability, and cannot effectively fix the optical glass, resulting in loosening or falling off during vibration, seriously affecting the accuracy of test results.

[0004] In addition, with the continuous development of optical glass manufacturing technology, its size and shape have become increasingly diverse. Traditional clamping devices often have difficulty adapting to this change and cannot meet the clamping requirements of optical glass with different specifications and thicknesses. Therefore, there is an urgent need in the market for a clamping device that can quickly, stably, and precisely clamp optical glass of various specifications and thicknesses, and at the same time is easy to operate and maintain.

The guide rail assembly 1 includes a linear guide rail 11. A sliding seat 12 is slidably mounted on the linear guide rail 11. The moving seat 2 is mounted on the sliding seat 12. One end of the linear guide rail 11 is connected with a positioning block 13. The moving seat 2 and the self-locking assembly 3 and the pressing head assembly 4 mounted on the moving seat 2 can stably move above the glass under the support of the guide rail assembly 1. A positioning hole 14 is provided in the positioning block 13. The positioning pin 36 is adaptively inserted into the positioning hole 14. While the self-locking assembly 3 drives the pressing head assembly 4 to press down the glass, the positioning pin 36 is inserted into the positioning hole 14 to realize the stable locking of the positions of the moving seat 2 and the self-locking assembly 3. The moving seat 2 includes a bottom plate 21 and a mounting frame 22. The mounting frame 22 is provided on the bottom plate 21. When one end of the bottom plate 21 abuts against one side of the positioning block 13, the axis of the positioning pin 36 is collinear with the axis of the positioning hole 14.
