Description

Technical Field

[0001] This utility model belongs to the field of geometric tolerance measurement technology and relates to a transition plate optical hole detection device. Background Technology

[0002] The transition plate is a component used in the final testing of aerospace computers. The positional accuracy of the mounting holes on the transition plate is critical, as the quality of the hole machining affects the overall testing efficiency. Typically, the positional tolerance of the holes must be less than φ0.1mm. Currently, the traditional method for measuring the hole position is using a coordinate measuring machine (CMM) to quantitatively detect the positional error of the mounted holes. While this method offers high accuracy, it suffers from drawbacks such as a cumbersome and complex measurement process, demanding environmental requirements, and high efficiency and cost. For example, measuring the holes on each transition plate requires approximately 5–10 minutes for CMM positioning and clamping, and about 3–4 hours for the actual measurement, which can easily delay production schedules.
