A well-known domestic pump manufacturer hopes to quickly obtain the appearance data of the original vacuum pump through a three-dimensional scanner, speed up the replacement, design and development of later product accessories, and improve the production efficiency of the vacuum pump.

Practical problems

1. Since the vacuum pump is imported from abroad, there is no data drawing, the parts need to be replaced later for the secondary design of the vacuum pump and the data reverse restoration drawing.
2. The traditional measurement methods (such as inspection tools, fixtures, three coordinates, etc.) are very cumbersome and time-consuming, and cannot accurately and quickly measure the vacuum pump.
3. The surface curvature of the vacuum pump changes greatly, the shape is complex, and the groove is variable, resulting in incomplete three-dimensional data obtained, and the secondary design of the vacuum pump cannot be carried out.

Vacuum pump accessories are a component of the pump, which work together with the pump body and other parts assembly. It is a part of the cover body, which is mainly connected with other parts, and plays a role of supporting and sealing fastening. Ensure that the pump works normally and does not hit gears. Pump accessories are made of castings. The contact end surface of the pump accessories and the pump body must have higher accuracy requirements. It is necessary to scan the three-dimensional data of the pump accessories and perform secondary design.

        Spray developer: improve the contrast of the background color on the surface of the sample and obtain better scan data.
        Paste mark points: enable the acquired data to be positioned and spliced in the scanning software
