Clamping device for Charpy impact sample

The invention discloses a clamping device for a Charpy impact sample. The clamping device comprises a bottom plate, a clamping frame and a handle, wherein the clamping frame and the handle are fixed to the two sides of the bottom plate respectively, and the clamping frame is fixed to the bottom plate in a scalable mode. Compared with the prior art, the clamping device for the Charpy impact sample is good in operation safety. An operator can hold the handle to conduct grinding, meanwhile, the hand and a grinding tool are separated through the fixing bottom plate, the problem that the hand is injured by a machine in the grinding process is avoided, and operation safety is good. 本发明公开了一种夏比冲击试样的夹持装置，包括：底板、夹持框及把手；其中所述夹持框及所述把手分别固定在所述底板的两侧，且所述夹持框可缩放地固定在所述底板上。与现有技术相比，本发明的夏比冲击试样的夹持装置具操作安全性好。操作人员可以手握把手进行磨削，同时通过固定底板将手和磨削工具隔离开，避免了磨削过程中机械伤害到手的问题，操作安全性好。
