Abstract

1496030 Welding by pressure CLARKE CHAPMAN Ltd 19 May 1976 [9 Aug 1975] 33279/75 Addition to 1440865 Heading B3R An automatically centring clamp, particularly for use in friction welding machines, comprises 2 pairs of co-operating jaws 14, 16 and 18, 20, the jaws 14, 18 of the pairs being movable in one direction, (e.g. rightwardly) by an hydraulic actuator piston 12 acting by way of an equalizing lever 26, and the co-operating jaws 16, 20 being movable in the opposite direction (e.g. leftwardly) by respective push bars (22, 24) fast with the jaws 14, 18 and acting on the jaws 16, 20 by way of equalarmed levers (not shown) fulcrummed on a fixed base pin. The equalizing lever 26 is pivoted on the piston 12 and has part-circular convex surfaces 32, 34 engaging blocks 36, 38 carrying the jaws 14, 18. For their retraction, the blocks 36, 38 have lugs 40, 42 received in equalizing lever recesses 44, 46. The equalarmed levers are provided with rollers for engagement with the bars (22, 24) and, directly or indirectly, with blocks carrying the jaws 16, 20. As shown, a two-diameter workpiece 28 is held by the jaws 14, 16, 18, 20 on the axis of a rotary chuck carrying a further workpiece to be friction welded to the large diameter end of the workpiece 28. Each pair of jaws is adjustable relative to the clamp centreline to accommodate varying diameter workpieces.
