JAW UNIT FOR TENSILE TEST AND TENSILE TEST APPARATUS USING THE SAME

摘要

Disclosed are a jaw unit for a tensile test, and a tensile test device using the same. The jaw unit for the tensile test comprises: a jaw housing with a gripping space on a center; a first jaw assembly arranged on a left side of an internal space of the jaw housing, partially exposed to the gripping space; a second jaw assembly arranged on a right side of an internal space of the jaw housing, partially exposed to the gripping space; a jaw cylinder moving the first jaw assembly forwards and backwards; an adjusting screw moving the second jaw assembly forwards and backwards; and a vertical displacement unit vertically moving the first and second jaw assemblies at the same time. The purpose of the present invention is to provide the jaw unit capable of improving an accuracy of the tensile test and the tensile test device using the same.
