Description

Product inner diameter measuring tool

Technical Field

The utility model relates to a measuring tool technical field especially relates to a product internal diameter measuring tool.

Background

In the processing process of the circular ring-shaped workpiece, because the manufacturing level is limited, when the subsequent processing procedure is carried out, the parameter of the inner diameter of the circular ring-shaped workpiece needs to be measured, and the procedure is directly related to the production efficiency and the processing quality of the workpiece. The size of the tubular workpiece is within the required error range, which is a standard for judging whether the tubular workpiece is qualified, so that the accurate measurement of the inner diameter size of the tubular workpiece is one of the very important processes in the manufacturing process. At present, the inner diameter of the circular ring-shaped workpiece is measured mainly by a caliper, the operation is complex, the working efficiency is low, the precision of the caliper measurement is low, the error is large, and certain use limitation is realized. To this end, we propose a product inside diameter gauge to address such problems.
