Universal precision displacement measurement auxiliary device and measuring method

Abstract

This invention disclosed a measuring method for micro-displacement. It was suitable for displacement less than 1 micron. It adopts balance lever system to amplify the displacement so that the precision was largely improved. It adopts two-level balance regulation system to decrease distortion so that the measuring process was stable. The advantages are as follows: the structure was simple; it is easy to handle; the cost was very low.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular refers to a device capable of doubling the precision of a displacement measuring instrument, which is convenient for micro-displacement measurement, and is especially suitable for the fields of precision machining and precision measurement. Background technique [0002] Displacement is the most basic physical quantity, and a large number of studies involve displacement measurement. Therefore, how to measure the displacement of the research object conveniently and accurately has always been a problem to be solved in the field of mechanical processing. Especially with the development of science and technology, the quality requirements of products are getting higher and higher, which leads to higher and higher requirements for displacement measurement accuracy. The measurement of small displacement (also called micro displacement) has become an important means of research proble...

Problems solved by technology

However, this type of instrument is expensive and requires very high conditions of use, so it is difficult to use it directly in on-site measurement

[0006] Therefore, for micro-displacement with a displacement of less than 1 micron, there is currently no low-cost precision micro-displacement measuring device that can be directly applied to the production site.
