A pendulum impact testing machine

Abstract

The utility model discloses a pendulum impact testing machine relates to impact test equipment technical field, including frame, support axle, rotation cover and swing bar, the end fixed with pendulum of swing bar still includes brake assembly, and brake assembly includes brake disc, contains ring groove and movable ring, and the side surface of movable ring towards swing bar is fixed with a plurality of alloy lugs around, and the rod body of swing bar is detachable with alloy insert block, and one end of alloy insert block extends to the inside of containing ring groove, and forms radial correspondence with alloy lug, the utility model discloses the setting of brake assembly, when pendulum completes the impact action, the sliding of active ring in containing ring groove, make alloy insert block fast insert between two alloy lugs, with the mechanical resistance and friction force between the both, rapidly consume the swing kinetic energy of swing bar, realize the quick brake of swing bar, avoid swing bar because of inertia repeatedly long -time swing, let test personnel can collect broken sample, replace the sample to be tested in time, improve test efficiency.
