This device usually sets a wire harness wheel on a rotating shaft, fixes one end of the produced wire harness on the wire harness wheel, and then while the wire harness is continuously produced, the rotating shaft is driven by a motor to rotate, and the rotating shaft then drives the wire harness wheel to rotate, thereby winding the remaining wire harness on the wire harness wheel, thereby achieving rapid winding of the wire harness.

[0004] However, the fast winding device used for wire harness production in the prior art has the problem of over-centralized winding of the wire harness, resulting in uneven winding of the wire harness at various locations on the wire harness wheel. Utility Model Content

[0021] In actual use, one end of the produced wire harness is threaded into the wire hole 4 between the two side plates of the wire harness wheel 3, and after passing through the wire hole 4, a knot is tied at the other end of the side plate of the wire harness wheel 3. Then, as the wire harness continues to be produced, the motor 1 is turned on to drive the shaft 2 to rotate. On the one hand, the rotation of the shaft 2 drives the wire harness wheel 3 to rotate through the action of the first keyway 12, the second keyway 13 and the flat key 14. On the other hand, the shaft 2 drives the driving gear 11 to rotate and drives the turntable 9 to rotate through the meshing of the driving gear 11 and the driven gear 10.

When the turntable 9 rotates from one hundred and eighty degrees, the push-pull rod 8 pushes the connecting rod 7 to move, and the connecting rod 7 pushes the annular plate 6 to move. When it rotates from ten degrees to three hundred and sixty degrees, the push-pull rod 8 pulls the connecting rod 7 to move, and the connecting rod 7 pulls the annular plate 6 to move, so that the wiring harness wheel 3 moves back to its original position along the flat key 14 from the other end of the rotating shaft 2, and so on and so forth, the wiring harness wheel 3 can make reciprocating motion along the axis of the rotating shaft 2 while rotating, so that the wiring harness is evenly wound on the surface of the wiring harness wheel 3; one end of the connecting rod 7 is rotatably connected to the connecting seat provided on the surface of the annular plate 6, and the annular plate 6 is rotatably connected to the annular plate groove 5 provided on the side plate surface of the wiring harness wheel 3, and when the wiring harness wheel 3 rotates, the annular plate 6 slides in the annular plate groove 5, so that the annular plate 6 can rotate without following the wiring harness wheel 3, and at the same time, the annular plate 6 can push and pull the wiring harness wheel 3 through the annular plate groove 5.
