Three-dimensional micro-motion fixed measuring device for optical measured object

Abstract

The invention discloses a three-dimensional micro-motion fixed measuring device for an optical measured object. The device comprises an instrument workbench, a U-shaped fixing assembly, three T-shaped fixing assemblies and a fine tuning assembly. The U-shaped fixing assembly is mounted on the instrument workbench, the three T-shaped fixing assemblies are respectively mounted on the peripheral wall of the instrument workbench, the connecting line of the axes of the two T-shaped fixing assemblies coincides with any diameter of the instrument workbench, the axis of the other T-shaped fixing assembly is perpendicular to the connecting line, and the three side walls of the U-shaped fixing assembly are each provided with one fine adjustment assembly. Measurement data of each section of the shaft part during measurement can be effectively controlled so that the measurement is close to a real value.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a three-dimensional micro-movement fixed measurement device for an optical measured object. Background technique [0002] The vertical optical meter is a precision optical mechanical length measuring instrument. It uses the method of comparing the gauge block with the parts to measure the micro-size of the object's shape. One of the instruments. It can verify the fifth-class precision gauge block or the first-class precision cylindrical gauge, and can measure the diameter of cylindrical, spherical, linear and other objects or the thickness of plate-shaped objects, and can remove the optical meter tube from the instrument, properly Installed on the machine tool, the gauge block is used to control the precision machining size. [0003] In practical applications, there are many types of precision measuring tools and high-precision optical meters, such as: smooth limit gauges,...

AI Technical Summary

Problems solved by technology

[0003] In practical applications, there are many types of precision measuring tools and high-precision optical meters, such as: smooth limit gauges, high-precision optical axes, etc., but because the measured object does not have a fixed device, human error will occur, resulting in inaccurate measurement

At present, there is no patent literature and non-patent literature at home and abroad to report the micro-motion device for fixing the measured object of this instrument, and there is no research report on the fixed object of this instrument, and there is no technical solution for this device.
