Technical Field

[0001] This utility model relates to the field of mechanical parts manufacturing technology, specifically a positioning device for mechanical parts inspection. Background Technology

[0002] Positioning devices for mechanical parts inspection are used to accurately determine the position and orientation of mechanical parts during the inspection process, ensuring the accuracy and reliability of the inspection results. Positioning devices for mechanical parts inspection include platform-type positioning devices, which are typically platforms with high-precision scales and positioning holes. Parts are placed on the platform, and their position is determined by their interaction with positioning elements on the platform.
