Description

Orifice chamfer gauge

Technical Field

The utility model relates to the technical field of workpiece detection, in particular to an orifice chamfer gauge.

Background

After the hole site on the workpiece finishes the processing of the hole port chamfer, the hole port chamfer needs to be detected. Wherein, when the maximum diameter of the chamfer is measured, a tool microscope is needed, and the detection precision is high. However, the detection efficiency is low and the method is not suitable for the condition that whether the detection is qualified or not is only needed. After the existing inspection tools are inserted into holes to be inspected by arranging an upper marking line and a lower marking line, if the top of a chamfer is positioned between the upper marking line and the lower marking line, the maximum diameter size of the chamfer is qualified; otherwise, the test result is disqualified. Although the gauge realizes rapid detection, one gauge can only be used for chamfer detection of one size, and the application range is small.
