(1) the resetting and lifting driving device drives the core rod to extend out;
(2) a piston rod of the pressing and clamping cylinder retracts upwards, the spring pushes the cross clamp upwards, and the cross clamp is opened;
(3) the whole hollow coil winding clamp descends to the right position;
(4) the wire feeding device feeds the enameled wire between the cross clamp and the core rod; correcting the position of an enameled wire by using a V-shaped support rod of a winding machine;
(5) a piston rod of the pressing and clamping cylinder extends out to drive the pressing and clamping piece to move downwards, the pressing and clamping piece presses the ejector sleeve downwards, the lower end of the ejector sleeve presses the cross clamp downwards, and the cross clamp rotates around the rotating shaft and clamps the enameled wire; descending the V-shaped stay bar;
(6) after the cross-shaped clamping wire is clamped, the whole body returns upwards by the distance of the diameter of the enameled wire;
(7) the fixture head rotates under the action of other rotary driving devices to enable the core rod to start winding, and 1 circle of winding is integrally lifted and retreated by the distance of one enameled wire diameter until the first layer of winding is completed;
(8) the clamp head stops rotating temporarily, a sleeve of the winding machine below the clamp head rises to enable the bottom of the core rod to be inserted into an inner hole of the sleeve, and the sleeve rises to jack the bottom of the coil; a winding area with a fixed distance is formed between the upper surface of the sleeve and the lower surface of the core sleeve, and the sleeve and the core sleeve synchronously ascend or descend;
(9) the fixture head continues to rotate in the same direction to drive the core rod to wind the second layer, and at the moment, the distance between 1 circle of sleeve and the core sleeve is equal to the diameter of one enameled wire until the second layer of winding is completed;
(10) the fixture head continues to rotate in the same direction to drive the core rod to wind a third layer, and the sleeve and the core sleeve synchronously and integrally ascend by a distance of one enameled wire diameter for 1 circle of winding until the third layer of winding is completed;
(11) the fixture head continues to rotate in the same direction to drive the core rod to wind the fourth layer, and at the moment, the distance between 1 circle of sleeve and the diameter of one enameled wire of the core sleeve is up to the preset number of layers of winding;
(13) cutting off the enameled wire;
(14) the cross clamp loosens the coil wire tail, and simultaneously the lifting driving device drives the core rod to retract into the core sleeve, so that the coil is smoothly demoulded.
9. A winding method using the air-core coil winding jig according to claim 8, wherein: in the step (14), the lifting driving device drives the core rod to retract into the clamp head, and the core rod stretches back and forth twice to avoid the coil from being adhered to the clamp.
