Problems solved by technology

[0003] At present, the structure of the traditional level tester is complex, the length of the transmission chain is measured, it is difficult to manufacture, and the detection efficiency is low; the traditional micrometer detection device needs to use high-precision standard gauge blocks or ultra-precision length measuring instruments, which is costly and difficult to operate. Trouble, low detection efficiency
[0004] Moreover, the most critical thing is that the traditional level meter calibrator and the traditional detection micrometer device are two different devices, which increases the cost of the equipment, and the detection efficiency is low

Abstract

The invention discloses an electronic digital display small-angle displacement measuring instrument which integrates functions of detecting indication errors of small-angle measuring instruments and detecting indication errors of amesdials. The electronic digital display small-angle displacement measuring instrument has the function of detecting indication errors of the small-angle measuring instruments including bubble levels, combined diagram levels, autocollimators and the like and has the function of detecting indication errors of the amesdials including gear lever comparators, reed-type comparators and inductance micrometers. The electronic digital display small-angle displacement measuring instrument is characterized in that a bedplate assembly is designed and arranged on a precision flat plate, a bedplate achieves small-angle inclination when a lifting device for regulating the small-angle inclination of the bedplate in a fine turning mode is rotated, and then indication errors of the small-angle measuring instruments or indication errors of the amesdials can be detected point by point according to required measurement intervals. The electronic digital display small-angle displacement measuring instrument is simple in structure, high in detection efficiency and stable and reliable in system.
