Abstract

The invention relates to the field of teaching appliances, and particularly relates to a precision measurement teaching instrument based on the Abbe principle. The precision measurement teaching instrument comprises a base which is provided with an X-direction guide rail. The X-direction guide rail is provided with an X-direction slide block which slides along the X-direction guide rail. The X-direction slide block is provided with a first reading head and a second reading head. The base surface is symmetrically provided with a first grating scale and a second grating scale. The second gratingscale is installed on a Y-direction guide rail and can slide along the Y-direction guide rail. The classic Abbe error, the aiming arm error and the guide surface error can be fully reflected and verified so as to effectively assist fully understanding of the characteristics and the properties of the Abbe principle for the students.

Description

Technical field: [0001] The invention relates to the field of teaching instruments, in particular to a precision measurement teaching instrument based on Abbe's principle. Background technique: [0002] Abbe's principle is a very important design principle in instrument design. The classical Abbe principle is a guiding principle for the design of measuring instruments proposed by the German scientist Ernst Abbe in 1890. He said: "In order for the measuring instrument to give correct measurement results, the measured dimension line must be arranged on the extension line of the movement direction of the reference element". Following the proposal of the Abbe principle in 1890, its concept and connotation have been continuously developed and enriched. In 2012, Professor Shi Zhaoyao of Beijing University of Technology and Professor Fei Yetai of Hefei University of Technology systematically summarized and summarized the development of the Abbe principle, revealing the The implic...
