AI Technical Summary
Technical Problem
Existing technologies are insufficient for accurately measuring small-sized, shallow pitting pits, and have large measurement errors on complex structures and curved surfaces, failing to meet high-standard testing requirements.
Method used
Design a standard ruler for pitting depth. Use multiple standard rulers, each with pre-drilled sample holes of different depths. Determine the pitting depth through visual comparison, abandoning direct contact measurement and adopting an indirect comparative observation method.
Benefits of technology
It enables rapid, high-precision, and convenient measurement of shallow pitting under complex working conditions, reduces subjective visual errors, improves detection efficiency, and is suitable for confined spaces and curved surfaces.

Abstract
本实用新型公开了一种点蚀深度标准尺，包括尺壳和多个标准尺，多个标准尺通过连接构件可旋转地设置于尺壳内，多个标准尺上分别预制有不同标准深度的样孔，不同标准深度的样孔共同覆盖一个深度区间，样孔用于通过与待测工件的点蚀坑进行视觉对比，以确定点蚀坑的深度。本申请摒弃直接接触测量，测量时，将深度相近的标准样孔与待测点蚀坑并排放置，通过肉眼或放大镜直观对比，找出视觉形态最接近的样孔，其标定深度即为估测值。工具为薄片状，可贴近任何表面进行测量，不受狭小空间、曲面或不规则基准面限制，省去固定、对齐等繁琐步骤，提升效率并降低操作技术要求。实现了复杂工况下对浅点蚀坑的快速、高精度便捷测量。
