Reverse 3D scanning solution for automotive shock absorbers -- Photo-type 3D scanner

With the wide application of 3D digital technology in the manufacturing industry, the design process of obtaining 3D data of automobile parts for many enterprises becomes simple and rapid, so as to solve the restriction of insufficient covering models and enable products to enter the market quickly. Automobile shock absorber is an important part of automobile engine, which requires high accuracy, so the design and drawing of shock absorber is very strict. Below, we use PTS 3D scanner to scan it and assist the designer to do reverse design.


The PTS 3D scanner is a new generation of scanner for industrial products. Compared with the traditional laser scanner and the three-coordinate measurement system, its measurement speed is increased by tens of times. Because of the effective control of the integration error, the overall measurement accuracy is greatly improved. It uses visible light to project specific grating fringes to the measuring working surface, and uses two high-resolution CCD digital cameras to take pictures of grating interference fringes. By using optical photo positioning technology and grating measurement principle, the complete point cloud of complex working surface can be obtained in a very short time. Its unique flow design and automatic splicing technology of point clouds from different perspectives enable scanning without the help of machine tools, the scanning range can reach several meters, and the scanning of large workpiece becomes efficient and easy.

client needs:

1. Scanning object: car shock absorber

2. Customer needs: quickly obtain the three-dimensional model of the automobile shock absorber and carry out reverse design, and directly provide the 3D solid map with high accuracy.

3. Difficulties that customers need to solve at present: automotive shock absorbers require high precision, traditional forward design drawing, slow efficiency, complete data of complex parts are difficult to obtain, and the accuracy of product processing is difficult to guarantee.

1. Preparation

First of all, surface treatment of scanned samples shall be carried out:

1) Because the 3D scanner uses optical method to scan the object, so some objects reflective surface, light transmission or absorption of the object need to do surface treatment spray imaging agent

2) Paste the marking points. The stitching of marking points is performed by the software algorithm. The 3D scanning system needs to superimpose the common markers identified between the two scans to make the two scans exist in a unified coordinate system, so as to achieve complete data Mosaic.

The highlights of a Blue light 3D scanner

1. Non-contact blue light 3D scanner

2. Quickly obtain 3D data of shock absorber

3. Reversible design, secondary design modification

4. Can quickly obtain 3D size

5. Reduce drawing modifications


Summary of 3D reverse solutions for automotive shock absorbers:

The blue-light camera-style 3D scanner performs accurate scanning and quickly provides customers with reverse engineering data processing. According to the physical model of the existing part (or called the original part), the process of reconstructing the original CAD model using various digital and CAD technologies. Jingyixun's Blu-ray Photographic 3D Scanner can directly obtain high-precision three-dimensional data of parts, and use software to construct curved surfaces or entities to make them the required three-dimensional data model for secondary design or direct processing. Realize "One machine in hand, worry-free design"!
