Description

Technical Field

[0001] This utility model relates to the field of scanning auxiliary device technology, and in particular to an optical scanning auxiliary device for damped vibrator parts. Background Technology

[0002] Optical scanning of parts is a technology that uses optical principles to acquire three-dimensional information about parts. By projecting specific light (structured light, laser, etc.) onto the surface of the part, the camera captures the reflection or scattering pattern of the light from a specific angle. Due to differences in the height and shape of the part surface, the light is deformed differently, and the system calculates the three-dimensional coordinate data of the part surface based on this.

[0003] Precision-cast high-pressure turbine engine damping vibrators and similar components are typically very small in size, yet require extremely high dimensional accuracy. Traditional gauges and measuring tools cannot measure all dimensions of these parts. While optical scanning equipment can inspect all dimensions, its accuracy is relatively low without the use of label points for positioning. Optical scanning equipment using label points suffers from the inability to reuse these points, resulting in excessive costs. Therefore, we designed an optical scanning auxiliary device for damping vibrator components to address these issues. Utility Model Content

At least two first limiting parts and second limiting parts are installed through the front and rear side walls of the base to limit the position of the part to be measured.

[0007] Preferably, the vertical cross-section of either side of the substrate is an octagonal structure.

[0008] Preferably, the substrate has multiple through openings, and the multiple support columns pass through the multiple through openings on the substrate.
