The car body is a space thin-walled shell with complex shapes. Nowadays, most of the main parts of the car body are stamped and welded by steel plates. The process requirements of the gold parts are very high.
At the same time, the sheet metal parts need to be bent to meet the curvature requirements of different parts of the car body. However, because the thin steel plate is easy to rebound, the accuracy is not easy to guarantee, which will eventually affect the installation of the whole vehicle.
Therefore, how to quickly obtain the deviation value of the body sheet metal part and the original drawing data, and provide accurate data support for timely adjustment of the deviation, has become an extremely important task for the manufacturer. Before that, it is necessary to obtain accurate data of body sheet metal parts!
The qualitative analysis of traditional inspection tools cannot obtain the deviation value
The traditional measurement method is to move the sheet metal parts to the inspection tool, and then use the plug gauge for qualitative analysis. If the plug gauge can be inserted into the corresponding hole, it is qualified, and if it cannot be inserted, it is considered unqualified. The measurement result can only be qualitatively impossible. Quantitative, and can only detect the deviation of the set position.
However, the traditional method cannot obtain the specific deviation value of the sheet metal part, and cannot perform the deformation analysis of the entire sheet metal part, which makes it impossible for the later manufacturer to accurately adjust the unqualified sheet metal part, which greatly affects the work efficiency.
Three-dimensional scanner quickly obtain accurate deviation values for deformation analysis
The global laser 3D scanner AXE can overcome the shortcomings of traditional inspection tools and obtain accurate 3D data of sheet metal parts conveniently and quickly, and then compare with the original data to quickly obtain the deviation value. It can also analyze the deformation trend of the entire sheet metal part, quickly generate an intuitive report, and provide strong data support for the later manufacturer to accurately adjust the sheet metal part.
Solution:
Use the global laser 3D scanner AXE to detect automobile body sheet metal parts, double the scan area, reduce marking points by half, improve work efficiency, accurately obtain 3D sheet metal data, generate stl data, and compare with original CAD data , Accurately obtain the specific deviation value of each point on the surface of the sheet metal part.
