Description

Technical Field

[0001] The invention relates to the technical field of stator winding machines, in particular to a stator winding machine. Background Art

[0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The stator is an important component in the motor. The rotation of the rotor is realized through the electromagnetic induction transmission between the stator and the rotor. The stator needs to be wound with copper wire for electromagnetic induction. To process this stator, it is necessary to first use a winding machine to wind each stator block, and then make the stator round after winding, and then match it with a shaping hoop. At present, the winding machine winds each stator block continuously and synchronously in the same direction. Then the motor is used to drive the flying fork with the wire to rotate. The flying fork rotates while moving back or forward, so that the wire is wound on the stator block along the spiral line, thereby making a stator block winding;

[0003] The prior art patent number CN202320477597.3 discloses a winding mechanism of a winding machine, which is provided with an upper tooth plate above the gear, and a buffer guide wheel is provided at the end of the upper tooth plate. When the gear rotates, the movement directions of the upper tooth plate and the lower tooth plate are opposite, and thus the movement directions of the buffer guide wheel and the winding guide wheel are opposite, so that the length of the wire harness between the fixed guide wheel and the winding guide wheel is unchanged, thereby ensuring the stability of the tension of the wire harness and the winding effect, and by providing guide rods on the upper and lower tooth plates, a shock-absorbing spring is sleeved on the circumferential outer part of the guide rod, so that when the lower tooth plate and the upper tooth plate are displaced, the shock-absorbing spring can play a buffering role, reduce the mechanical vibration of the fixed guide wheel and the winding guide wheel, and further ensure the winding stability.

One end of the two connecting plates 801 is hinged to the inside of the fixing seat 10. The surfaces of the two connecting plates 801 are provided with limiting grooves 802. The limiting grooves 802 extend in a winding manner to the end of the connecting plate 801 away from the fixing seat 10.
