Measuring device for lateral expansion of impact specimen

Abstract

The invention relates to a device used for metering solid deformation. In order to solve the problems that according to an existing impact specimen sideward swell capacity measurement device, radiation protection is not taken into consideration and radioactive impact specimen sideward swell capacity can not be directly measured, the invention provides an impact specimen sideward swell capacity measurement device. The device comprises a base, a measurement jacking block and a dial indicator. Slide rails are arranged on the base. The front end of the measurement jacking block is of a structure including a plurality of jacking cones with the cone ends aligned with one another, and a push rod is arranged at the rear end of the measurement jacking block. A baffle is arranged in front of the jacking cones of the measurement jacking block, and the face, facing towards the jacking cones, of the baffle is provided with a specimen clamping base with a clamping groove. When the measurement push rod is pushed, the measurement head of the dial indicator can make contact with the sideward swell portion of an impact specimen. The impact specimen sideward swell capacity measurement device solves the radiation protection problem in the radioactive impact specimen sideward swell capacity measurement process, long-distance direct measurement is achieved, and the impact specimen sideward swell capacity measurement device is quite convenient and rapid to operate and use, and low in cost.

Description

technical field [0001] The invention relates to a device for measuring the deformation of a solid, in particular to a device for measuring the side expansion of an impact sample. Background technique [0002] The lateral expansion of impact specimen is an important test data obtained by impact test, which is mainly used to characterize the ability of metal materials to resist deformation under impact load. At present, the device used for measuring the lateral expansion is simple in structure, and the impact sample is directly operated by hand during the measurement, and the measurement process is relatively simple. [0003] In the field of reactor materials, the requirements for material properties often take into account the radiation damage factor, so the impact samples that need to be measured for lateral expansion often have strong radioactivity. In this case, the existing lateral expansion measurement devices cannot be directly applied to the measurement of the lateral...
