Abstract
The apparatus and process relate to aligning ends of wire conductors extending from coil members inserted in slots of a core () of a dynamo electric machine to join the ends of at least two wire conductors (EP, EP, EP, EP, EP) by means of a welding operation; wherein the ends to be joined are aligned along radiuses (R, R) of the core (), and wherein spacing (S, S) exists between two adjacent radiuses (R, R) of the core (). This apparatus and this process provide for a first alignment unit () to which the following steps are made to be performed: positioning a first member () in a first spacing (S) existing on one side of a first radius (R) of said core (); positioning a first abutment portion (') at a first position situated radially between a first group of ends (EP) to be joined and a second group of ends (E) to be joined, said first and second group of ends being aligned along said first radius (R); positioning a second member () in a second spacing (S) existing on the opposite side of the first radius (R); positioning a second abutment portion (′) at a second position situated radially between said first group of ends (EP) to be joined and said second group of ends (E) to be joined; positioning a first pusher () at a radially outer position relative to said core () for pushing said first group of ends (EP) to be joined against said first abutment portion (′); positioning a second pusher () at a radially inner position relative to said core () for pushing said second group of ends (EP) to be joined against said second abutment portion (′); arranging first means () configured for relatively moving the first member (), the second member (), the first abutment portion (′) and the second abutment portion (′) in an axial direction (Z, Z′) of the core (); arranging second means () configured for relatively moving the first radial pusher () and the second radial pusher () in the radial direction (R, R′) of the core (); arranging third means () configured for moving the first member () and the second member () one towards the other in a circumferential direction (CS, CS′) of the core ().
