Riveting station assembly

Abstract

A mobile production riveting system comprising a power actuated hand operated "gun" tool assembly for pulling and automatically collecting the mandrels of inserted blind rivets and panel mounted associated equipment including power supply, control valve, pressure regulator, vacuum transducer, mandrel retrieval system, hydraulic reservoir, and other support equipment for adapting a general factory air supply to power the hand tool under finger trigger control. Unusually fast cycle time results from a combination of improvement features including the limitation of vacuum venturi airflow for mandrel retrieval to power-off portion of the cycle, the use of air pressure in lieu of a mechanical gun piston return spring, and a non-pumping system with respect to eliminating recycling of actuating hydraulic fluid to and from the hydraulic reservoir. An integrated assembly of all system equipment for operating the hand tool through connecting hose lines on a compact mobile suspension panel including a mandrel retrieving system accomodates efficient service over a wide range of operating space.
