Abstract

The invention discloses a calibration device and method for a laser displacement measurement system, and the device and method are used for carrying out on-site calibration on the laser displacement measurement system on a high-precision rigidity measurement instrument, and belong to the field of measurement and test standards. According to the invention, a gauge block is reliably positioned and conveniently placed on the three beads through a workbench tool and a three-bead measuring mechanism with magnetism, so that the problem that the measurement precision is influenced by the gas film generated between the gauge block and the three-bead measuring mechanism due to installation, repeated positioning of the gauge block and the like is solved, and the field calibration of the laser displacement measurement system is realized.

Description

technical field [0001] The invention relates to a calibration device and a calibration method for a laser displacement measurement system, which are used for calibrating a laser displacement measurement system on a high-precision stiffness measuring instrument, and belong to the field of measurement and testing standards. Background technique [0002] The electromechanical system has a large number of high-precision (force value indication error ±0.5%, displacement indication error ±1μm), small displacement (range 0-2mm) static load stiffness measuring instruments (hereinafter referred to as stiffness measuring instruments), these stiffness measuring instruments It is mainly used for the static stiffness measurement of elastic elements, and the measurement of force and micro-deformation is realized through the force value measurement system and the laser displacement measurement system. At present, there is no unified calibration specification and method for this type of equ...
