1,266,945. Riveting. HUCK MFG. CO. 26 Sept., 1969 [30 Sept., 1968], No. 47606/69. Heading B3U. A tool for setting a pin and collar type fastener includes a piston 50 comprising a forward rod portion 54 operatively connected to pin gripping jaws 68 and a rearward rod portion 56, both rod portions 54, 56 being connected to a head portion 52 and mounted for reciprocation in bores 42, 36 which have their axes X eccentric to the axis Y of the main bore 14 in which the head portion 52 reciprocates. The piston 50 is moved rearwardly by fluid under pressure introduced through a passage 90 in an adapter 38, passage 92 in a cylinder head 28, a tube 96 and port 100. The jaws 68 are thereby moved inwardly to grip the pin and apply an axial force thereto whilst the collar is swaged by an anvil 22. The jaws 68 are urged into the closed position by a follower 82 urged against the jaws 68 by 0-rings 84. After setting, the piston 50 is moved back by applying fluid pressure through passages 102, 104. The jaws 68 are engaged by an annular shoulder 76 of a release member 72 to cause them to open to release the pin. A collar ejector 74 is moved by the rod portion 54 to cause the swaged collar to be ejected from the anvil 22. |
