Clamping tool for processing stripe degree sample

Technical Field

The utility model belongs to the technical field of the glass clamping, concretely relates to clamping frock is used in stripe degree sample processing.

Background

The striae is an important technical index of optical glass, which must be monitored in daily production to ensure the quality of optical glass products, and the grade of the striae directly affects the value of the products. Currently, the streak quality of an optical glass product is judged by processing a streak-size sample. With the increasing of optical glass products, the processing amount of the streak-size samples is also increasing. Therefore, the efficient processing of the streak sample is particularly important for the production line quality monitoring and the product streak quality judgment.

In the current stage of processing of the stripe degree sample, a special clamping tool is used for clamping, after a base plate is installed, milling is carried out on a plane rough grinding machine, fine grinding is carried out on a plane high-speed fine grinding machine, and polishing is carried out on a plane high-speed polishing machine. Chinese utility model patent that the grant publication number is CN212497221U just discloses an optical glass stripe degree clamping frock for test sample processing, including clamping base plate, setting at the location connecting portion of clamping base plate upside and set up the anchor clamps framework in the clamping base plate downside, be equipped with the sample chamber in the anchor clamps framework, be provided with two at least sample mounting on the lateral wall in sample chamber.
