AI Technical Summary

Technical Problem

Existing technologies for measuring the distance between the end face of a medical plastic-coated spring tube and the end face of the plastic coating layer suffer from large errors, high measurement difficulty, and low efficiency, failing to meet the accuracy and efficiency requirements of mass production.

Method used

The system employs a combination structure of handle, blind hole, and mandrel. The blind hole provides radial limit for the spring tube, the mandrel provides axial guidance, and the annular step surface can be visually compared through the observation window to achieve rapid positioning and accurate measurement.

Benefits of technology

It improves testing efficiency and accuracy, reduces measurement errors, adapts to the testing needs of spring tubes of different specifications, reduces equipment costs, and enhances quality control.

Abstract

The application provides a medical outer-plastic-springs-tube end face distance detection device, which comprises the following steps: connecting the first end of the handle with the closed end of the let-blank hole; arranging the first end of the fixed core rod at the hole bottom of the let-blank hole, and arranging the fixed core rod coaxially with the let-blank hole; symmetrically arranging the first observation window and the second observation window, which penetrate through the two ends of the side wall of the let-blank hole; forming the first annular step surface and the second annular step surface on the end face of the opening end of the let-blank hole; inserting the medical outer-plastic-springs tube from the opening end of the let-blank hole, inserting the second end of the fixed core rod into the inner hole of the medical outer-plastic-springs tube, abutting the spring end face of the medical outer-plastic-springs tube with the hole bottom of the let-blank hole, observing the relative positions between the outer-plastic layer end face of the medical outer-plastic-springs tube and the first annular step surface and the second annular step surface, and judging the product qualification, so as to solve the problems of difficult operation and low efficiency of the traditional measuring tool.
