Description

Laser interferometer adjusting platform
Technical Field

With the rapid development of aerospace and automobile manufacturing industries in China, more parts are changed from simple surfaces to complex surfaces, the requirement on the machining precision of the parts is higher and higher, the multi-axis linkage numerical control machine is used as main equipment for machining the parts, the requirement on the machining precision is higher, and in order to ensure that the numerical control machine can machine the parts in a high-precision and high-stability state, the numerical control machine must be subjected to error detection and compensation regularly. At present, the most applied instrument for detecting the error of the positioning accuracy of the translational shaft of the multi-shaft numerical control machine tool is a laser interferometer.

The laser interferometer is the best detection tool for detecting the positioning error of the translational shaft of the numerical control machine tool, and the working principle is as follows: the light beam from the laser head enters the linear interference mirror and is split into two beams. One beam (called the reference beam) is directed to a mirror mounted on the beam splitter, and the other beam (the measurement beam) passes through the beam splitter to a second mirror. Both beams are then reflected back to the beam splitter where they are recombined and directed back to the laser head where a detector within the laser head monitors the interference between the two beams. To ensure sufficient signal strength throughout the axis of motion of the machine and to reduce cosine measurement errors, the laser beam of the laser system must be collimated so that it is parallel to the axis of motion.
But because the space is narrow and small to some lathe, when having no firm ground and enough space to erect the tripod by survey axis periphery, just can only fix the laser head at survey axis end through the magnetic meter seat, and laser head and speculum all can't realize about the translation action this moment, at the process of adjusting luminance, if the light skew appears, just can only adjust through about or remove the speculum from top to bottom, and the speculum of originally fixing also can appear about the skew about the removal process, has increaseed the degree of difficulty of adjusting luminance undoubtedly. Therefore, in order to solve the above problem, it is urgently needed to design a laser interferometer adjustment platform, which assists a laser interferometer or a reflector set to realize flexible and accurate vertical and horizontal displacement adjustment at low cost, reduces the dimming difficulty, and quickly realizes laser collimation.
