Generator cover
A famous wind turbine manufacturers,in order to improve existing products,need to get high accurac-y data of wind turbines.
Customers need to detect the number of products a lot, if use the traditional
measuring tool,the efficiency will very low.
Wind power generator hood volume is big, but screw hole is small, 3D scanner not
only requires wide scan range, and high precision.
In recent years, wind power has developed rapidly in emerging markets.In the national
policy support and under the background of energy supply tension, Chinese wind power
especially wind power equipment manufacturing industry was rapid rise, had become a place
of global wind power is the most active.
A well-known wind power equipment manufacturers need to improve some existing
products.The company needs to purchase 3D scanner,obtain the 3D data of wind generator
cover to reverse design and product quality detection.
Wind power generator cover size：8 meter × 3 meter
Screw hole：Diameter 1 centimeter
Working equipment：α7000 and HL-3DP
Data accuracy requirements：Satisfy the standard of industrial production
Steps：
1st ：preparatory work
Pasting mark point:makes scanning data can locate splicing in the scanning software.
Pasting magnetic encoding point: makes 3D photogrammetric system get the object's
Three-dimensional coordinates value.
2nd ：Three-dimensional photogrammetry
Using high resolution digital camera Shooting object from different angles,These
photos after dealing with the software, can get accurate spatial coordinates of all
reference points.
3rd ：Scanning
Using 3D scanner “α7000” multi-angle scanning the wind power generator cover.
This scanner’s breadth is 800×600mm,so it’s a professional large workpiece 3D scanner.
The whole scanning process uses only two hours,and the overall error of a total 40
screw holes is 0.012 mm,so it’s a professional large workpiece 3D scanner.
4th :Data processing
Bring the point cloud data into the reverse engineering software “Geomagic Studio ",
can generate STL triangular mesh surface data.And then,use some mainstream design software
carries on the post-processing(eg:Pro/E, UG) , can speed up the development of new
products.Subsequent product’s 3D data cooperate with detection software “Geomagic-
Qualify”,can rapidly generating straightforward detect graphic report to show the
difference between products and digifax.At the same time also can capture and embody the
deviation of wind power generator cover.
