Abstract

The invention discloses multifunctional extensometer marking apparatus. The apparatus comprises a rigid support and an amesdial, wherein the rigid support comprises a pedestal and a main support part,which is provided with an upper fixture and a lower fixture which are positioned on the same axis; the upper fixture is in sliding connection with the main support part through a sliding block connecting piece, the lower fixture is fixedly connected with the main support part and the pedestal through a lower clamping block, one end of the main support part is fixedly connected with the pedestal,the other end of the main support part is connected with the amesdial through an upper clamping block, the micrometric screw of the amesdial passes through the upper clamping block and is connected with the sliding block connecting part, the sliding block connecting part is in sliding connection with the main support part through a guide rail sliding block, and the upper clamping block and the lower clamping block are symmetrically and respectively arranged at two ends of the main support part. The multifunctional extensometer marking apparatus is integrated with the marking functions of a longitudinal extensometer and a transverse extensometer, the metrological verification cost is greatly reduced, and the marking efficiency is improved; meanwhile, a high-precision displacement micrometeris provided, according to the micrometer, the structure is reasonable, the performance is stable, and the primary indicators reach the advanced level of similar measuring instruments.

Description

technical field [0001] The invention relates to the field of measurement and testing of extensometers, in particular to a multifunctional extensometer calibration instrument. Background technique [0002] With the rapid development of society and economy, transverse extensometers have been continuously used in ships, automobiles, diesel engines, generator locomotives, chemical machinery and other fields, and the demand for measurement and testing of transverse extensometers has become increasingly urgent. [0003] However, the currently used transverse extensometers have the following main problems: the measurement methods are not uniform, lack of authoritative calibration instruments, and lack of corresponding traceability. Contents of the invention [0004] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide a multifunctional extensometer calibrator. [0005] In order to achieve the above ...
