Description

Measuring tool for rapidly and accurately measuring bushing thin-wall parts

Technical Field

The utility model belongs to the technical field of thin-wall part machining, and particularly relates to a measuring tool for rapidly and accurately measuring bushing thin-wall parts.

Background

In actual production and processing, when the outer diameter of the thin-wall part of the bearing bush is measured, the measurement is inaccurate due to the property that the product is easy to deform, and then, some parts are damaged due to the fact that some parts are false and out of tolerance, and great economic loss is caused for companies. The main reasons for inaccurate measurement are the following two points: 1. elliptical deformation of the outer diameter of the part; 2. the conventional measurement method is to measure by using a micrometer, and the measurement of the size is unstable due to uneven force application in the measurement process.
