Description

Auxiliary tool for micrometer verification Technical Field The utility model belongs to the technical field of micrometer verification, and particularly relates to a clamping auxiliary tool for micrometer verification. Background The micrometer has various specifications, such as ：(0～25)mm、(25～50)mm、(50～75)mm、(75～100)mm、(100～125)mm、(150～175)mm、(200～225)mm、(300～400)mm、(400～500)mm, etc., and the micrometer frames designed by each micrometer manufacturer are different. Aiming at the requirements of the JJG 21-2008 micrometer verification rule, the micrometer with the upper measurement limit larger than 150mm can detect the indication error of the micrometer head according to the detected point of the micrometer with the help of a special gauge (0-25 mm). When the micrometer head indication error is detected by means of the special detection tool, how to clamp and fix the micrometer to install the special detection tool and detect the indication error is particularly important. The clamping auxiliary tool for micrometer verification in the market can only clamp the micrometer with a small measuring range below 150 mm. When the micrometer with the upper limit of detection and measurement being larger than 150mm is used, no corresponding clamping auxiliary tool is used, and a plurality of inconveniences are brought to detection and measurement. Disclosure of utility model The utility model aims to provide a clamping auxiliary tool for micrometer verification, which can be used for clamping and fixing micrometer of micrometer frames of different manufacturers in the verification process of micrometer with the upper measurement limit being more than 150mm, and carrying out verification work on micrometer head indication errors by means of a special detection tool.
