A ceramic sheet positioning fixture
By designing a ceramic disc positioning fixture that combines a lever lifting mechanism and a rotary clamping cylinder with a guide sleeve structure, the shortcomings of traditional fixtures in terms of positioning accuracy and stability have been solved. This achieves sub-millimeter precision positioning and rapid tape removal, improving processing consistency and ease of operation.

AI Technical Summary
Traditional ceramic sheet positioning fixtures are difficult to use manually to ensure uniform material adhesion, resulting in hole deviations, cracks, and wrinkles, making it impossible to achieve sub-millimeter level positioning accuracy.
A ceramic sheet positioning fixture was designed, which adopts a lever lifting mechanism and a rotary clamping cylinder combined with a guide sleeve structure. The precise positioning of the ceramic sheet and the quick removal of the tape are achieved through the pin plate and the top column structure. The lever-type clamping device and the guide sleeve structure ensure that the ceramic sheet is subjected to uniform force and prevent displacement and vibration.
It achieves sub-millimeter level positioning accuracy, prevents displacement and vibration during processing, improves processing consistency and tape removal efficiency, avoids wrinkling, and ensures stable positioning of ceramic sheets.
