[0002] In vacuum devices, optical window glass plays a crucial role. It is not only a structural component of the device, but also directly affects the performance and reliability of the device. The sealing surface of the window glass is a key part for sealing with other components (such as glass, ceramics, metals, and composite materials, etc.). The polishing quality of the sealing surface plays a crucial role in ensuring the sealing performance of the vacuum device. Effectively sealing the vacuum device can prevent external air and moisture from entering, thereby protecting the electronic components inside the device from the external environment and ensuring the stability and service life of the device.

In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0031] Please refer to Figures 1 to 3 , some embodiments of the present utility model provide an adjustable polishing die assembly for the square step sealing surface of optical glass, which includes:

[0032] An adjustable polishing die, which includes a platform 10, and a polishing block 20 is arranged on the platform 10;

[0033] A fixed fixture for clamping the glass, which is located on both sides and above the adjustable polishing die.

[0034] In some embodiments, optionally, the platform 10 can be a square structure, and positioning holes 12 are respectively provided at the four corners of the platform 10 for fixing the die assembly on the horizontal vibrating table 50.

[0035] In some embodiments, optionally, according to the positioning holes and die design, the platform 10 can be a cuboid or cube structure.

[0037] In some embodiments, optionally, the fixing piece 11 is provided with an oblong hole 13 for adjusting the distance between the polishing blocks 20.

[0038] In some embodiments, optionally, a screw 30 corresponding to the oblong hole 13 is arranged on the oblong hole 13. The polishing block 20 and the platform 10 can be fixed into one body through the screw 30; the polishing block 20 can also move in the oblong hole 13 of the fixing piece to adjust the fixing position of the polishing block 20.

[0047] 2. Adjust the distance between the polishing blocks according to the distance between the opposite side angles of the optical glass (the angle refers to the intersection of the step surface and the step side surface), and fix the polishing block 20 on the platform 10 through screws passing through the long circular holes 13 on the fixing pieces 11;

[0048] 3. Place the square step optical glass to be processed on the polishing block, so that the sealing surface of the optical glass to be polished is in close contact with the polishing block 20 (there is no gap between the two);
