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

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

This utility model discloses a ceramic tile positioning fixture, including a fixture housing and a material. The material is placed on the top of the fixture housing, and a pin plate and a lever lifting mechanism are provided on the top of the fixture housing. An auxiliary pressure plate is provided inside the lever lifting mechanism, and a pressure plate connecting plate is provided on the top of the auxiliary pressure plate. A flipping shaft and a pressure rod are installed on the inner side of the pressure plate connecting plate. This ceramic tile positioning fixture, by installing a pin plate on the top of the fixture housing, removing the fixing tape and taking out the steel frame, and using the pressure plate in conjunction with the flipping mechanism, stabilizes the ceramic tile, preventing displacement or vibration during processing, achieving sub-millimeter precision positioning, and ensuring consistency in processing or inspection. The use of a lever-type clamping device allows for single-handed flipping and pressing of the pressure rod to stack and position the ceramic tile, thus reducing the likelihood of wrinkles and resulting in more even force distribution during use.
