Abstract

The invention relates to an auxiliary device of a measuring instrument, in particular to an auxiliary calibration device for outer diameter micrometer calibration and inner diameter dial indicator. The auxiliary calibration device includes a base plate and at least two measuring frames arranged side by side on the base plate; each measuring frame is provided with at least one supporting portion allowing the measuring anvil of the outer diameter micrometer or the micrometer screw to be erected on the measuring frame; A support part of a certain measuring frame is arranged side by side with at least one supporting part arranged on other measuring frames, so that the measuring anvil and the micrometer screw of the outer diameter micrometer can be erected on the two measuring frames at the same time. The auxiliary calibration device can assist the calibration of the zero position of the outer diameter micrometer and the calibration of the inner diameter dial indicator.

Description

technical field [0001] The invention relates to an auxiliary device of a measuring instrument, in particular to an auxiliary device for calibrating an outer diameter micrometer and an inner diameter dial indicator. Background technique [0002] At present, the commonly used method for measuring engine cylinder diameter in the automobile maintenance industry is: first calibrate the zero position of the outer micrometer, and then adjust the size of the outer micrometer; then put the inner diameter dial indicator on the adjusted outer micrometer Calibration, after the calibration is completed, take the inner diameter dial gauge to measure the cylinder. However, in the actual operation process, the calibration steps of the inner diameter dial indicator are complicated and the operation is difficult; moreover, it is difficult to fix and maintain the level of the outer micrometer and the inner diameter dial indicator during the calibration process, resulting in inaccurate calibrat...
