Device and method for positioning ends of at least first pair of legs of hairpin conductors

Abstract

The present invention relates to a device, a system and a method for positioning the ends of at least first pair of legs of hairpin conductors extending from a stator core with respect to a welder tool. The device (300) comprises a first clamping element (302) and a second clamping element (303), wherein said first clamping element (302) and said second clamping element (303) are independently moveable radially. Said first clamping element (302) has a first clamping surface (304) and said second clamping element (303) has a second clamping surface (305), wherein the first and second clamping surfaces (304, 305) are radially facing each other. The clamping elements (302, 303) form a first, preferably radially inner, receiving section (306) between the first clamping surface (304) and the second clamping surface (305), having a first radial width (307) dimensioned to axially receive and clamp a first pair (5) of legs during welding, and a second, preferably radially outer, receiving section (308) inside the first and second clamping element, having a second radial width (309), dimensioned to receive at least a further pair (6) of legs during welding of the first pair of legs.
