Abstract

The invention discloses an adjustable standard clearance device, which comprises a knife straight edge, a working platform, a clamp, a vertical shaft, a shaft sleeve, a lever mechanism and a helical pair, wherein the knife straight edge is arranged on the vertical shaft through the clamp and is located on a working surface of the working platform; the vertical shaft and the shaft sleeve are perpendicular to each other; the vertical shaft is connected to one end of a lever and the other end of the lever is connected to a helical pair mechanism; the lever is in contact connection to the shaft sleeve through a support base. The adjustable standard clearance device disclosed by the invention is simple and practical; the vertical shaft is driven to do axial motion to generate a continuous and adjustable standard clearance through the helical pair mechanism and the lever; applied to metrological verification of the knife straight edge, the adjustable standard clearance device is convenient to implement daily verification and can improve the working efficiency.

Description

technical field [0001] The invention belongs to the field of standard gaps, and particularly relates to an adjustable standard gap device, which can generate continuously adjustable standard gaps and is applied to the measurement and verification work of a knife-edge ruler. Background technique [0002] The main purpose of the standard gap is to use the standard gap generated by it to compare with the measured object in the measurement of the light gap method. The light gap method is a method to judge the size of the gap by observing the amount of visible light gap passing through the actual gap. Any gap smaller than 0.03mm can be tested by the light gap method as long as it can produce a visible light gap. The light gap method is simple and intuitive, and has high measurement accuracy. This method is widely used in metrology and inspection institutions and production practices. The light gap method can be used in the metrological verification of the knife-edge ruler and t...
