Abstract

1394773 Riveting KHARKOVSKY AVIATSIONNY INSTITUT 2 May 1973 20797/73 Heading B3U A hammer for setting a rivet comprises a cylinder 9 mounted in a housing 1, a piston 11 for setting the rivet movable within the cylinder 9, a radially movable mechanism 18-20 mounted on the end of the cylinder 9 for centring the cylinder 9 relative to a rivet and resilient means 14 for retaining the piston 11 at the other end of the cylinder 9. The mechanism for centring the cylinder 9 includes levers 20 pivoted to an end face of a sleeve 18 fixed to the cylinder 9 and a sleeve 19 rotatably mounted with the aid of balls 22 on the cylinder 9. When the sleeve 19 is rotated, the levers 20, which extend through slots (26, 27) (Fig. 4, not shown) in the sleeves 18, 19, are pivoted about their axes 25 to close upon the stem of the rivet thereby centring the cylinder 9 relative to the rivet. When the sleeve 19 is released, it is returned by a torsion spring 28 to its initial position in which the levers 20 are free of the piston 11. The piston 11 is retained at the other end of the cylinder 9 by pins biased by an annular spring 14 into engagement with an annular groove in the piston 11. An elastic gasket 16 is positioned between the housing 1 and cylinder 9. When a trigger 7 of the hammer is actuated, a cartridge 5 is fired and the piston 11 is accelerated by the expanding gases when the bias of the spring 14 has been overcome. The gases are exhausted through ports 29, 30.
