AI Technical Summary

Technical Problem

The existing technology has problems such as large measurement errors and inconvenient operation when detecting the outer diameter of easily deformable plastic products. In particular, the engagement contact of the caliper easily causes deformation, and it is difficult to ensure that the detection center coincides with the measured center.

Method used

An outer diameter measuring device is used, including a base, a measuring standard, a flexible lasso and a winding module. By tightening and loosening the flexible lasso and combining it with a measuring instrument, accurate measurement of the outer diameter of easily deformed plastic products is achieved. The flexible lasso is tightened and wrapped around the periphery of the product to be measured, and the difference in expansion and contraction is obtained through the measuring instrument to calculate the actual outer diameter.

Benefits of technology

It significantly improves the detection accuracy and operational convenience, reduces the probability of deformation of plastic products, and can quickly and accurately measure the outer diameter of easily deformed plastic products.

Abstract

The present application relates to the outer diameter detection method of the easily deformed plastic product, and the detection comprises the following steps: S1, the pre-adjustment process of measurement; S2, the measurement process. The present application not only greatly improves the coincidence rate of the center of the detection and the center of the plastic product, but also the force applied to the circumferential sleeve of the plastic product is centripetal force, that is, the probability of causing the plastic product to produce deformation is significantly reduced, thereby greatly improving the detection accuracy and being convenient to operate. At the same time, under the premise that the probability of causing the plastic product to produce deformation is small, not only can the detection of the outer diameter larger than the design outer diameter of the easily deformed plastic product be carried out, but also the quick verification of the fixed outer diameter product can be quickly carried out to increase the accuracy of the measured product size parameter.
