Abstract

The invention discloses a three-dimensional deformation precision inspection device of a measuring apparatus, comprising a fixed bracket and a longitudinal plate, wherein a supporting seat I and a supporting seat II are arranged on the longitudinal plate; a guide rod I is arranged on the supporting seat I and a guide rod II is arranged on the supporting seat II; a transverse plate is arranged above the longitudinal plate; a guide block I and a guide block II are arranged at the bottom part of the transverse plate; a transmission mechanism I is arranged on the longitudinal plate; a supporting seat III and a supporting seat IV are arranged at the upper part of the transverse plate; a guide rod III is arranged on the supporting seat III; a guide rod IV is arranged on the supporting seat IV; a lower flat plate is arranged above the transverse plate; a guide block III and a guide block IV are arranged at the bottom part of the lower flat plate; a transmission mechanism II is arranged on the transverse plate, and a measuring apparatus mounting platform capable of adjusting elevation is connected with the upper part of the lower flat plate. According to the invention, three-dimensional deformation of a deformable body in a three-dimensional space can be conveniently simulated, and precision, reliability and accuracy of the measuring apparatus in deforming monitoring can be effectively inspected.

Description

technical field [0001] The invention relates to an inspection device, in particular to a three-dimensional deformation accuracy inspection device of a measuring instrument. Background technique [0002] At present, various deformation monitoring instruments are widely used in deformation monitoring. Through the monitoring of the deformable body by various instruments, not only can the intuitive data such as the deformation speed, displacement size and displacement direction of the deformable body be obtained, but also through the analysis of the monitoring data, it can be used to deeply understand the deformation mechanism of the deformable body and the characteristics of deformation and failure. As well as the prevention and treatment of deformed bodies, etc., provide the basis for actual measurement. [0003] However, how to check the precision, reliability and accuracy of these instruments in deformation monitoring is a primary and critical issue. Due to the different d...
