        1. Industry applications

          Fuel injection pump three-dimensional scanning

          Fuel injection pump 3D scanning case

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

          Practical problems

          1. The use of traditional measuring methods (such as inspection tools, fixtures, three coordinates, etc.) is very cumbersome and time consuming, and it is not easy to accurately and quickly measure and detect the structure of the fuel injection pump.

          2. The shape of the fuel injection pump is complex, and the grooves have different shapes and curved surfaces. The amount of 3D data acquired is incomplete and cannot be redesigned.

          Hualang solutions

          Fuel injection pumps are an important part of automotive diesel engines. Considered as the "heart" component of a diesel engine, it can cause the entire diesel engine to malfunction if something goes wrong. The company hopes to use the 3D scanner to scan the fuel pump three-dimensionally and carry out secondary design and improvement of the product. In response to customer needs, Hualang 3D engineers proposed solutions for use: 3D scanner HL-3DS+ (fast acquisition of high-precision 3D data of fuel injection pump) + reverse design software Geomagic Studio (converting fuel pump point cloud data into triangular mesh surface) Data) +Pro/E, UG and other mainstream design software for post-processing, speed up the secondary design of the fuel injection pump.

          1. Preparation in the early stage:

          Spraying the developer: Improve the background color contrast of the sample surface for better scan data.

          Paste mark points: Make the acquired data be positioned and stitched in the scanning software.

          2. 3D scanning:

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