APPARATUS FOR CHECKING WORKING PRECISION OF V-NOTCH OF IMPACT TEST PIECE

摘要

PURPOSE: A device for confirming the V-notch working precision of an impact testing piece is provided to precisely process the impact testing piece and to accurately confirm impact properties of a steel material, thereby enabling to select the proper steel material. CONSTITUTION: A device for confirming the V-notch working precision of an impact testing piece includes a fixing device(100), a reference device(200), a photographing device(310), and a display device(320). The impact testing piece in which a V-notch is formed is placed on the fixing device. The reference device is arranged in one side of the fixing device, thereby providing reference images for forming the V-notch. The photographing device is arranged in the other side of the fixing device to be faced the reference device, thereby photographing the V-notch of the impact testing piece. The display device displays images of the V-notch of the impact testing piece photographed by the photographing device and the reference images of forming the V-notch provided by the reference device. The fixing device includes a bed(110), a fixing member(120), and a regulating member.
