In order to reduce the man-machine interaction link of the measuring process, the automatic measuring mode is adopted, the product measuring automation can be greatly improved, the multi-process and multi-station measuring mode is adopted, the measuring work efficiency is improved, and the production period is shortened to the maximum extent.
The method is provided aiming at some defects in the aviation blade measuring process, but the device is not limited to aviation blades, and has great adaptability and practicability to parts with high precision requirements, complex and various measuring procedures, requirements on rapid measurement and the like.
The existing blade measurement process is that an on-line operator sends a blade to a three-coordinate measurement chamber, the measurer confirms blade information and adjusts a corresponding detection program on a computer, then the blade is positioned on a workbench by using a V-shaped block, a magnet and the like, then the three-coordinate measuring machine is operated manually to perform rough positioning to establish a detection coordinate system, then the program is operated to measure blade parts according to the process, the three-coordinate measuring machine automatically generates a switching report of a blade root and the like, then the operator calls blade software to input related parameters, starts to measure the blade profile, and stores the measurement report into a corresponding file format to complete measurement. Most of the operation steps still need manual operation, and if the human-computer interaction is not carried out in time, the three-coordinate system stops to wait. As can be seen from the whole process, the single-piece measuring process is adopted, the measuring efficiency is low, and the actual production requirements are difficult to meet.
