A hardness testing device for optical glass production

Abstract

The invention discloses a hardness detection device for optical glass production, which comprises a column, on which a feeding pipe is installed through a bearing mechanism, and two elastic through holes are opened in the column through a bottom partition and a top partition, The vertical gear rod is installed in the column through the cooperation of the sliding mechanism and the bottom plate, and the horizontal gear rod is installed in the vertical column through the cooperation of the limit groove and the limit block, and the horizontal gear rod and the column are fixed by the return spring. A push plate is installed, and the transmission gear meshing with the horizontal gear rod and the vertical gear rod is installed in the rotation of the column. A storage tube is fixedly installed between the bottom partition and the top partition. The drop mechanism passes through the column. A return pipe is installed. The advantage is that it can perform multi-point compression testing without affecting the fixing effect of optical glass, and can perform multi-position, multi-height impact resistance hardness testing, and can automatically complete the recovery and replenishment of falling balls, with high efficiency and The detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of optical glass, in particular to a hardness detection device for optical glass production. Background technique [0002] Optical glass is a kind of special glass commonly used in optical instruments. After the optical glass is produced, it is usually tested by a hardness testing device to judge whether the compressive hardness and impact hardness of the optical glass are up to standard. After retrieval , Patent No. CN211013878U Chinese Utility Model Authorized Patent discloses a hardness detection device for glass production, including a base, a pressure sensor is installed on the left side of the base, and a There is a support column, the upper side of the support column is provided with a plastic film, the upper side of the base is connected to the first sliding rod at both ends, and the upper side of the slider is fixed with a connecting column; [0003] The above-mentioned device still has the followi...

AI Technical Summary

Problems solved by technology

[0004] 1. The device adopts the method of clamping and squeezing the glass to detect the hardness. This method can only detect the compressive hardness of the optical glass, but cannot detect the impact hardness of the optical glass, and the detection range is narrow;

[0005] 2. Some existing devices cannot collect, replenish and reuse the falling balls used to hit the glass when testing the hardness of the glass, and cannot change the drop height and drop position of the falling balls. The experimental data obtained from the test Less, the accuracy of the detection result is lower;
