After the stator winding 40 is wound by a plurality of coils 41 and assembled in a plurality of previous steps such as assembly, a plurality of wire ends 42 are arranged at intervals and are in a substantially vertical state but not completely aligned, so that the wire end wire arranging mechanism for arranging the stator coils needs to perform bending wire arranging operation on the wire ends 42 so as to facilitate the clamping of a subsequent bus plate. The stator winding 40 has a plurality of slots 43 in its circumferential outer wall, the slots 43 being capable of being positioned by the positioning clamp assembly 20 in a manner to be described below.

The wire clamping assembly 10 comprises at least one support 11, a support plate 12 penetrating through the support 11, a sliding table cylinder 13 arranged on the support plate 12, a wire clamping cylinder 14 arranged at the output end of the sliding table cylinder 13, and a clamp 15 arranged at the output end of the wire clamping cylinder 14.

The support plate 12 is arranged on the support post 11 in a penetrating manner and is fixed on the support post 11 through a screw. The height position of the support plate 12 on the support 11 can be adjusted through knob screws, so that the wire clamping position can be adjusted through cooperation with the positioning clamping assembly 20.

The output direction of the sliding table cylinder 13 faces the positioning clamping assembly 20, and the sliding table cylinder 13 can drive the wire clamping cylinder 14 to reciprocate in the direction. The thread clamping cylinder 14 can control the clamp 15 to perform opening and closing operations, so that the clamp 15 can clamp the thread end 42. The slipway cylinder 13 pulls back, so that the thread ends 42 are tidied and bent. After the rotation assembly 30 controls the positioning and clamping assembly 20 to rotate by one angle, the above operation is repeated, thereby completing the bending and line-finishing operation of the stator winding 40.

The positioning and clamping assembly 20 comprises a central column 21, a lifting cylinder 22 arranged on one side of the central column 21, a lifting plate 23 arranged at the output end of the lifting cylinder 22, a lifting column 24 inserted in the central column 21, a baffle rod 25 inserted on the lifting column 24, a spring 26 arranged at one end of the lifting column 24, two adjusting rods 27 arranged at the other end of the lifting column 24, and a positioning seat 28 arranged around the lifting column 24.

The central column 21 is hollow along the length direction, so that the lifting column 24 and the spring 26 are slidably inserted into the central column 21. Two first sliding grooves 211 for inserting the baffle rod 25 are formed on the circumferential outer side wall of the central column 21, the baffle rod 25 is fixedly arranged on the lifting column 24 in a penetrating manner, and two ends of the baffle rod respectively penetrate through the first sliding grooves 211.

The fixed disk 212 is fixedly connected with the rotating assembly 31 by a screw. The limiting disc 213 is mainly used for limiting the lifting plate 23, and a specific limiting manner will be described below.

One end of the lifting plate 23 has an arc opening matched with the central column 21, and an inner side wall of the arc opening is matched with a circumferential outer side wall of the central column 21 and is positioned between the fixed disc 212 and the limiting disc 213, so that the lifting plate 23 is limited by the limiting disc 213, and the stop lever 25 is positioned in the moving direction of the lifting plate 23. The output direction of the lifting cylinder 22 is parallel to the length direction of the center column 21, and the lifting cylinder 22 can drive the lifting plate 23 to reciprocate between the fixed disc 212 and the limit disc 213. When the lifting plate 23 moves towards the fixed disc 212, the lifting column 24 is pushed to the end of the first sliding groove 211 towards the fixed disc 212, and the lifting column 24 moves towards the spring 26 under the driving of the lifting rod 25 and compresses the spring 26, so that the lifting column 24 can have potential energy towards and away from the spring 26 when the lifting plate 23 moves towards the limiting disc 213, and the end of the lifting column 24 away from the spring 26 can cooperate with the adjusting rod 27 and the positioning seat 28 to achieve the function of fixedly clamping the stator winding 40, and a specific clamping mode will be described below.

One end of the center post 21, which is far away from the spring 26, is provided with a bar-shaped groove 214, two ends of the bar-shaped groove 214 are respectively provided with a pin shaft 215 in a rotating mode, and the pin shafts 215 are used for penetrating through the middle section of the adjusting rod 27.
