Impact and impact-rotary tool testing apparatus using rotary speed and impact energy

摘要

A test stand has a base supporting standards on which are mounted a crossbar and an adjustably locatable header. The header supports an actuator for raising and lowering the crossbar which holds V-blocks for engaging the handles of an impact or impact-rotary tool and which applies downward pressure to the tool. The tool chuck is fitted to the top of a guide rod whose lower end passes with a sliding fit through a disc to which it is keyed and bears against a piston in an hydraulically pressurized cylinder. Sensors detect rotation of the disc and movement of the piston to provide information to a computer as to impact energy and rotary speed. A manifold fitted with sensors for temperature, pressure, and flow rate supplies operating air to the tool. The computer includes a database with stored information as to past history of the tool and the manufacturer's recommended operating specifications to which the measured data is compared.
