Positioning mechanism for welding torches. |
摘要 |
<p>1. A positioning mechanism for welding torches of the type mounted on a torch carrier (2), through which the torch (1) axially passes, characterised in that it comprises : - a screwthreaded ring (4) which is fixed to the carrier (2) and which is provided with a spherical support surface (6) ; - a castellated nut (8) which is screwed on to the ring (4) at one end and provided at the other end with an axial hollow internal seat (10) provided with a spherical bearing surface (12) ; - an intermediate ring member (14) provided with a conical bore (16) and bearing against the bearing surface (12) of the seat (10) by means of a spherical surface (18) ; and - a split insulating ring member (20) co-operating internally with the torch body (1) and externally with the conical bore (16) and with the support surface (6) by means of a spherical bearing surface (22) ; the support surfaces (6, 18) and the bearing surfaces (22, 12) being described by radii whose common centre coincides with the adjustable point of entry (24) of the torch.</p> |
