Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of machining optical auxiliary device, especially relates to an optical mirror adjusting mechanism. BACKGROUND

[0002] The mirror is a special optical element, which is covered with a layer of precisely designed oxidation coating for enhancing the reflection performance of specific wavelengths. This oxidation coating can effectively improve the optical reflectivity and imaging quality, but due to its fragile surface, it is easily affected by scratches or wear, so special attention is needed during use and adjustment to avoid direct contact with the lens surface as much as possible, thereby prolonging its service life and ensuring the stability of optical performance. In the process of automobile component stamping and injection molding, the mirror with special oxidation coating is of great significance. Its main function is used for optical measurement and quality detection, especially in the consistency control of surface precision and shape of stamping and injection parts. This mirror can improve the reflectivity of optical measurement equipment, ensure the intensity and accuracy of detection light, and accurately capture the subtle defects of component surface, such as surface roughness, warping or deformation. In addition, the oxidation coating mirror is also very important for non-contact detection of complex curved surface components, which can avoid surface damage caused by contact between detection tool and component, further improving production quality and efficiency.

[0003] At present, there are many problems and deficiencies in the use of mirrors, mainly in the following aspects:

[0004] Firstly, the mirror adjustment process lacks a dedicated auxiliary adjusting device, and the adjustment operation mainly depends on manual operation. Since direct contact with the lens is required, it is easy to cause damage to the oxidation coating, such as peeling off and scratching. This not only affects the optical performance of the lens, but also shortens its service life and increases the frequency of maintenance and replacement.

[0005] Secondly, there are deficiencies in the adjustment accuracy. Manual adjustment is difficult to achieve accurate positioning, especially in scenarios where optical equipment requires high-precision reflection angles. The error of manual adjustment may cause light path deviation, thereby affecting the performance of the overall system and the reliability of test results.

[0006] In summary, the current use of mirrors still has room for improvement in terms of adjustment, accuracy, etc. It is urgent to solve these problems through optimization design and technical upgrading to improve the reliability and convenience of the mirror. INVENTION CONTENTS
