Precision measurement is a sub-field in the manufacturing industry that revolves around "high-precision parameter detection". Its core is to use advanced measurement technologies, equipment and algorithms to accurately quantify parameters such as the size, shape, position and surface quality of parts or products to ensure that they meet design standards and production requirements.
Large-stroke precision measurement, as an important sub-field, focuses on achieving micron-level or even submicron-level measurement accuracy within a large measurement space, thus resolving the contradiction between "large/ultra-large workpieces" and "high-precision inspection requirements".
It needs to overcome the technical difficulties of "equipment stability and error compensation caused by large stroke" while retaining the core accuracy requirements of precision measurement. It is an indispensable quality control method in aerospace, automobile manufacturing, large mold and other fields.
The fully automatic gantry measuring instrument is a high-precision and high-efficiency measuring device that integrates optics, mechanics, and electronics, enabling precise measurement of large strokes.
In terms of the transmission system, its three axes often use high-precision silent linear guides, and the ball screws are high-precision ground. They are paired with servo motors for full closed-loop control, which combines high precision and high speed. The imaging system is equipped with a high-definition camera and an automatic zoom objective lens, which can realize zoom measurement, and there is no need to reselect the scale when changing the magnification.
However, this type of equipment also has certain drawbacks. On the one hand, it has high environmental requirements, and its stability is greatly affected by the foundation. If the foundation changes, it will directly affect the stability and accuracy of the measuring machine. On the other hand, if there is vibration in the environment, it is not possible to use a vibration damping device directly between the measuring machine and the ground. Instead, the foundation as a whole must be treated to prevent vibration, which is costly.
To address these issues, Huizhou Zhongke Advanced Manufacturing Co., Ltd.'s RATJONAL series of large travel gantry vision measuring machine are also high-precision, large-size automated measuring devices. This equipment adopts a gantry structure design, featuring a large stroke and high stability, making it suitable for rapid and precise measurement of three-dimensional dimensions, geometric tolerances, and surface contours of large workpieces.
