Benefits of technology

This inventor describes an improved device that can accurately determine if there're small holes or cracks on a surface being tested inside during manufacture. It uses multiple point measurements instead of just one spot size at once, resulting in more precise results compared with previous methods like touching probes.

Problems solved by technology

Technological Problem: Current techniques like measuring inside diameters require multiple steps involving different tools that can be difficult to handle accurately with precision. Additionally, current devices only measure one aspect of the entirety of the measured object's interior without considering its shape or dimensions.

Abstract

The invention provides a multi-point laser internal diameter measuring instrument and a measurement calculation method thereof. The multi-point laser internal diameter measuring instrument comprises a handle, a master control box, a connecting rod, a rotating rod and a spherical probe. The multi-point laser internal diameter measuring instrument adopts non-contact laser measurement and achieves continuous measurement by rotating the spherical probe. Four laser range finders measure the inner wall of a workpiece to obtain a four point distance group, a measurement section plane internal diameter value corresponding to a triangle composed of any three points in the four point distance group is solved, the geometric average of the solved internal diameter values is calculated, and the solved internal diameter values are compared to obtain the minimal value, namely, the plane internal diameter value of the workpiece. The measuring instrument is high in measurement precision and simple to operate, man-made errors of traditional contact-type measurement are effectively eliminated, and a rapid and precise measurement instrument and method for workpiece deep hole measurement is provided.
