Positioning device and method for positioning wire ends in the manufacture of an electrical machine

Abstract

A positioning device (10; 50; 60) for positioning wire ends (14) in the manufacture of an electrical machine (12) has a positioning unit (13) which has an alignment element (22a) and a counter-alignment element (22b) which are arranged one above the other in two parallel planes (16, 18) and can be displaced relative to each other along a displacement path (34), being at least partially superimposed or superimposable. Thereby, the alignment element (22a) has at least one through recess (24a) and the counter alignment element (22b) has at least one counter through recess (24b), which are arranged and designed in such a way that a clear positioning passage (99) perpendicular to the two planes (16, 18) of the alignment element (22a) and the counter-alignment element (22b), through which the at least one wire ends (14) can extend and the cross-sectional area of which can be varied by displacing the alignment and counter-alignment elements (22a, 22b) with respect to each other. In order to distort the wire ends as little as possible, the at least one through recess (24a) on the aligning element (22a) and the at least one counter through recess (24b) on the counter-aligning element (22b) each have two rectilinear edge sections (30a, 30b, 30c, 30d) which run in the respective plane (16, 18) at an oblique angle to the direction of displacement (FIG. 3).
