A well-known domestic fuel injection pump manufacturer hopes to quickly obtain the appearance data of the original fuel injection pump through a three-dimensional scanner to accelerate the development of new products.

Practical problem

1. Using traditional measurement methods (such as inspection tools, jigs, three coordinates, etc.) is very cumbersome and time-consuming, and it is not easy to accurately and quickly measure and inspect the structure of the fuel injection pump.

2. The shape of the fuel injection pump is complex, and the shapes of the grooves on each surface are different, and there are many curved surfaces. As a result, the amount of three-dimensional data obtained is incomplete, and secondary design cannot be carried out.

Holon solutions

Fuel injection pump is an important part of automobile diesel engine. It is regarded as the "heart" part of the diesel engine. Once it goes wrong, it will cause the entire diesel engine to malfunction. The company hopes to use a three-dimensional scanner to scan the fuel injection pump three-dimensionally for the secondary design and improvement of the product. In response to customer needs, Hualang 3D engineers proposed to use in the solution: three-dimensional scanner HL-3DS+ (quickly obtain high-precision three-dimensional data of the fuel injection pump) + reverse design software Geomagic Studio (convert the point cloud data of the fuel injection pump into a triangular mesh surface Data) + Pro/E, UG and other mainstream design software for post-processing to speed up the secondary design of the fuel injection pump.

1. Preliminary preparations

Spray developer: improve the contrast of the background color on the surface of the sample and obtain better scan data.

Paste the mark point: make the acquired data be positioned and spliced in the scanning software.

2. 3D scanning

The scanning speed of the 3D scanner (HL-3DS) is fast, and it only takes 10 minutes to obtain the 3D data of the fuel injection pump, and the data accuracy is as high as 0.02mm. The three-dimensional scanner (HL-3DS) uses extrapolation multi-frequency phase shift grating technology, code point calibration technology and automatic splicing technology. Import the fuel injection pump data into three-dimensional reverse engineering software (Geomagic) for processing, and import the processed data into mainstream design software such as Pro/E and UG to perform reverse engineering of the engine. Speed up the development of new products and improve engine performance.
