Machine for applying low velocity impacts to mechanical structures

摘要

It permits low velocity impacts to be applied with high precision, offering a wide range of energies, internal or external application, from any angle of incidence and measuring the energy delivered and returned.;It includes an impactor element (1) coaxially joined to a launcher element (11) and both in turn to a base structure (27). In the primed position this assembly is linked by means of some pivoting catches (24) and actuators (43), governed by the control system for the machine. The impactor (1) has in its central body (2) a flange (7) which is retained in the pivoting catches (24) and in its rear end it includes a propulsion valve assembly (4). The launcher element (11) includes the tube (10) of the pneumatic propulsion cylinder, with two side windows (12) for the passage of the valve retainer (13), others with two side windows (19) for the passage of the retaining yoke (20) of the emergency energy absorber (39).
