In order to ensure that the stator winding is not loose during the transferring process, a plurality of hairpin clamping blocks 3 are arranged inside the socket 1, and the hairpin clamping blocks 3 are used for pushing the support legs 72 in each strip-shaped jack 2 inwards along the radial direction of the socket 1 so as to prevent the support legs 72 from moving.
In this embodiment, the inner end of the hairpin fastening block 3 extends into the strip jack 2 from the outside to the inside along the radial direction of the socket 1; a pressure spring 4 used for pushing a hairpin fastening block 3 is arranged in the socket 1, and the hairpin fastening block 3 is connected with an outward expansion driving mechanism 5. The compression spring 4 is used for pushing the hairpin clamping block 3 inwards, and the outward expansion driving mechanism 5 is used for pulling the hairpin clamping block 3 outwards so as to avoid friction between the hairpin clamping block 3 and the support leg 72 in the process of taking the stator winding out of the jig.
As shown in fig. 3 and 4, in the present embodiment, the end of the hairpin fastening block 3 inserted into the bar-shaped insertion hole 2 is wedge-shaped, and the inclined surface 31 of the wedge-shape is open toward the top of the bar-shaped insertion hole 2. So that the legs 72 can push the hairpin gripping blocks 3 outward during insertion of the legs 72 of the stator windings into the bar-shaped insertion holes 2.
