Hardness detection device for optical glass production

Abstract

The invention discloses a hardness detection device for optical glass production. The hardness detection device comprises a stand column, a discharging pipe is installed on the stand column through a bearing mechanism. Two elastic through holes are formed in the stand column through a bottom partition plate and a top partition plate. A vertical toothed bar is installed in the stand column through cooperation of a sliding mechanism and the bottom plate. A transverse toothed bar is slidably mounted in the stand column through cooperation of a limiting groove and a limiting block, and a push plate is fixedly mounted between the transverse toothed bar and the stand column through a reset spring. A transmission gear meshed with the transverse toothed bar and the vertical toothed bar is rotationally installed in the stand column, and a storage pipe is fixedly installed between the bottom partition plate and the top partition plate. The stand column is provided with a material return pipe through a falling mechanism. According to the device, multi-point compression resistance detection can be carried out under the condition that the fixing effect of optical glass is not affected, multi-position and multi-height impact resistance hardness detection can be carried out on the optical glass, falling balls can be automatically recycled and supplemented, the efficiency is high, 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;
