Abstract

PURPOSE: To make it possible to continuously execute an impact test, by providing the liquid agent filling chambers for weight adjustment symmetrically with respect to the center of gravity or the center of impact of the hammer, and making it possible to stagelessly vary the internal capacity, maintaining said symmetrical relation.
CONSTITUTION: One pair of cylindrical filling chambers 6 of the same shape are installed so that they are symmetrical against the center of impact (or center of gravity) 5 and also are located on the axial line 4. Also, the filling passage for injecting a liquid agent for weight adjustment is installed to said one pair of filling chambers 6 so that it passes through the center of impact 5 and also it is symmetrical against the surface which is vertical to the axial line 4. Then, a liquid agent is injected from the inlet, the inlet is closed by the seal screw 12, and the weight of the liquid agent to be injected or the weight of the hammer is adjusted. Accordingly, as for this impact test hammer, only the weight can be varied without varying the position of the center of impact or the center of gravity of the hammer, and also said variety can be afforded continuously and stagelessly.
