The working principle of the invention is as follows:
the present invention is for winding a plurality of slots for a half core stator 55 having a semicircular shape.
According to the invention, the halving angle B is calculated according to the halving semicircle 180 degrees of the number of the wire grooves 51 of the half-core stator 55, for example, when the halving angle B is 8 wire grooves, the angle between two adjacent wire grooves with the halving angle 23 degrees is 23 degrees, and meanwhile, the symmetrical deflection angle A is designed according to the size and the width of the wire grooves 51 (the center line of the notch of the wire groove is taken as the symmetrical deflection center line L). The invention takes the center of a circle of a half iron core stator 5 as an indexing center, takes a slot opening of a slot of the half iron core stator 5 as a winding center, and calculates a symmetrical deflection angle A by using the winding center RO.
Before the invention works, a worker or a robot clamps one end of the half-core stator 5 on the clamping seat 361 through the stator clamp assembly, and pulls the line on the tensioner to the winding needles 255 of the upper winding fork arm and the lower winding fork arm and leads out the line.
When the invention works, a worker starts the winding machine, the front-back moving motor 31 drives the front-back moving plate 33 to move back and forth, the left-right moving motor 32 drives the left-right moving plate 34 to move left and right, the lifting motor drives the lifting rotating shaft to lift, and the rotating motor drives the lifting rotating shaft to rotate, so that the half iron core stator 5 on the fixture support frame moves to the winding opening of the front and back wire baffles, and the other end of the half iron core stator 5 is aligned with the winding opening to be inserted, so that the first wire slot of the half iron core stator 5 is aligned with the winding slot (namely, the winding needle 255 is aligned with the notch center of the first wire slot, thereby determining the initial point O1 of the indexing center).
Then, the rotating motor drives the lifting rotating shaft to rotate, so that the half iron core stator 5 rotates left by an angle A, then rotates right by an angle A2 times, then the rotating motor drives the half iron core stator 5 to swing left and right (the center line of the slot opening of the wire slot is taken as the center line of the deflection) by a swinging angle of 2 times A, and in the process of swinging the half iron core stator 5 left and right, the winding needle 255 is always aligned with the slot opening of the first wire slot, so that winding is realized.
Meanwhile, the winding motor drives the upper winding rotating shaft and the lower winding rotating shaft to rotate, so that the upper winding fork arm, the lower winding fork arm and the winding needle 255 are driven to rotate, the winding needle 255 pulls the line, and the front guide plate and the rear guide plate guide wire strips wind on the winding slot and the first wire slot of the half-core stator 5 until the winding needle 255 winds the first wire slot (when the number of times of winding through the winding fork arm reaches the set number of times).
After the winding needle 255 is wound around the first slot, the back-and-forth moving motor 31 drives the back-and-forth moving plate 33 to move back and forth again, the left-and-right moving motor 32 drives the left-and-right moving plate 34 to move left and right again, and the rotating motor drives the half-core stator 5 to move and rotate so that the center of the half-core stator 5 returns to the position of the initial point O1 of the indexing center, and at this time, the second slot of the half-core stator 5 is aligned with the winding slot, i.e., the winding needle 255 is aligned with the slot center of the second slot, at this time, the half-core stator 5 has rotated by an angle B at the initial point of the indexing center, thereby realizing indexing.
After the winding needle 255 is aligned with the notch of the second wire slot, the winding yoke continues to rotate to wind, and the rotating motor continues to drive the half-core stator 5 to swing back and forth with the notch center line of the second wire slot as a deflection center line and also with a swing angle of 2 times of the angle A, the winding needle 255 pulls the line, and the winding is performed on the second wire slot of the half-core stator 5 until the winding needle 255 winds the second wire slot fully.
Similarly, the winding yoke winds all the wire slots on the half core stator 5 to full lines.
After all the wire slots on the half iron core stator 5 are fully wound with the wire, the wire winding machine of the invention can spirally wind the tail end of the wire on the winding thimble of the half iron core stator 5, when the winding thimble winds the tail end of the wire, the stator clamp mechanism drives the half iron core stator 5 to ascend, the half iron core stator 5 is separated from the winding openings of the front and rear wire guide plates, and the stator clamp mechanism drives the half iron core stator 5 to sequentially move in the front, back, left and right directions, so that the tail end of the wire is spirally wound on the winding thimble. After the winding thimble winds the tail end of the line, the invention fuses or cuts the line.
The upper and lower double-station winding machine can simultaneously complete the winding work of the two half-core stators 5. The machine frame provided by the invention has the advantages that the double winding stations are arranged as the upper winding station and the lower winding station, and one of the upper winding station and the lower winding station shares the winding motor and one set of stator clamp mechanism, so that the machine frame is low in production cost, compact in structure, small in size and small in occupied area. After the winding work is finished, the invention can also carry out winding treatment on the wire tail, thereby facilitating the subsequent wiring work of the semi-iron core stator 5 by workers.
