Pump cover 3D scanning case

Release time：2024-08-01 Views：73

A well-known pump manufacturer in China hopes to quickly obtain the appearance data of the original pump cover through the 3D scanner, carry out the secondary design of the pump cover, accelerate the development of new products, and improve production efficiency.

Facing problems

Practical problems

1. The surface of the pump cover has a large change in curvature, a complicated shape, and a groove on the surface, resulting in an incomplete amount of three-dimensional data acquired, and the secondary design of the pump cover cannot be performed.

2. Traditional measuring methods (such as gages, fixtures, three coordinates, etc.) are very cumbersome and time consuming, and the pump cover cannot be accurately and quickly measured.

Solution

solutions

The pump cover is part of the pump and works with parts such as the pump body. It belongs to the cover type parts, and it mainly connects other parts and plays the role of support and sealing fastening. Ensure that the oil pump works normally and does not leak oil and does not tooth the gear. The pump cover is made of castings, and the end face of the pump cover and the pump body must have higher precision requirements. The three-dimensional data of the pump cover should be scanned for secondary design.

1. Preparations in the early stage

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

Paste mark points: The acquired data is positioned and stitched in the scanning software.

2, 3D scanning

The 3D scanner 3DS+ scan speed is fast, it takes only 15 minutes to obtain the 3D data of the pump cover, and the data precision is high. 3D scanner 3DS+ uses extrapolation multi-frequency phase shift grating technology, code point calibration technology and fully automatic splicing technology. The pump cover scan 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 perform reverse design of the pump cover. Accelerate the development of new products and improve the production efficiency of enterprises.
