AI Technical Summary

Technical Problem

When inspecting the diameter and position of the spherical end face of a part, the existing inspection tool uses screws and pins to fix the mandrel and template together, which makes template replacement cumbersome and affects convenience and inspection efficiency.

Method used

The template adopts a fixed box and slider structure, and uses the cooperation of the first spring and the slider to realize the quick disassembly and installation of the template. Combined with the telescopic rod and the second spring, the ease of template disassembly is improved, and the template is protected by a protective sleeve to avoid deformation and ensure the accuracy of testing.

Benefits of technology

It enables quick template replacement and protection, improves the convenience of inspection tools and the accuracy of inspection, and meets the quality control needs of mass production.
