The utility model relates to the technical field of impact tests, in particular to a pendulum impact testing machine. Two cylinders are horizontally arranged above the supporting block, telescopic rods of the two cylinders are oppositely arranged, a laser sensor is horizontally arranged on one side of the swing path of the pendulum bob, and laser rays of the laser sensor intersect with the swing path of the pendulum bob. The laser sensor is electrically connected with the two air cylinders respectively, when a metal sample is placed on the supporting block, the two air cylinders clamp the metal sample together, and the situation that the metal sample deviates and influences the test effect due to vibration generated during equipment operation is avoided; when the pendulum bob freely swings downwards from a high position, the pendulum bob passes through a laser detection point of the laser sensor, the two air cylinders can be controlled to synchronously and rapidly contract before the metal sample is impacted
