[0023] In this preferred embodiment, the adjusting device 21 includes a second linear guide rail 21-4, which is horizontally fixed in front of the mounting plate 22. A second slider 21-1 is movably arranged on the second linear guide rail 21-4, and a base 21-3 is fixedly arranged thereon. A motor bracket 20 is fixedly connected to the second slider 21-1.

[0032] This invention is used in cooperation with the invention patents CN202111096941.6 and CN202111096169.8.

[0033] Working principle: The piston head of the cylinder 28 presses against the bottom of the hollow screw 17, so that the movable thimble 25 presses against the concentric winding composite die; when the servo motor 14 rotates forward, the driving pulley 9 drives the driven pulley 6 to rotate, and the driven pulley 6 drives the cam 3 to rotate. When the cam 3 rotates, it pushes the swing arm fixing plate 11 away from the movable thimble along the hollow screw 17. At the same time, the cam 3 pushes the swing rod 8 to swing, and the shaping block 16 pats and shapes the windings of the upper module A of the concentric winding composite die from the inside to the outside. At the same time, the module B moves synchronously from the inside to the outside. When the windings on the module A are sequentially patted and shaped, the module B reaches the position of the module A; then the servo motor 14 rotates reversely, and the cam 3 rotates to drive the swing arm fixing plate 11 to move along the hollow screw 17 towards the movable thimble; at this time, the invention patent CN202111096941.6 winds the electromagnetic wire evenly on the module B. After winding, the piston head of the cylinder 28 presses against the bottom of the hollow screw 17, so that the movable thimble 25 presses against the concentric winding composite die; the servo motor 14 rotates forward, and the shaping block 16 pats and shapes the windings of the module B on the concentric winding composite die from the inside to the outside. At the same time, the module C moves synchronously from the inside to the outside. When the windings on the module B are sequentially patted and shaped, the module C reaches the position of the module A; after the shaping block 16 sequentially pats and shapes the windings on the module C and the module D from the inside to the outside, the shaping of the multi-layer windings is completed.

[0034] Features of the present invention:

[0035] 1. Under the action of the connecting rod, the servo motor moves synchronously with the cam and the swing arm fixing plate, and the shaping block is used to shape the multi-layer windings, making the multi-layer windings flat and neat, and reducing the gap between the multi-layer windings.

[0036] 2. The motor bracket is connected to the first slider of the first linear guide rail, enabling the servo motor to move up and down easily; a second linear guide rail is also horizontally installed on the first linear guide rail, facilitating the left and right movement of the motor bracket, making it convenient to install the belt and adjust the tightness of the belt, avoiding the phenomenon of belt slipping, and ensuring the stable operation of the belt.

[0037] 3. The guide posts and ball bushings guide the swing arm fixing plate, making the movement of the swing arm fixing plate smooth and free.

[0038] 4. The swing arm is made of spring steel and has elasticity. When shaping the windings, the shaping block will not deform the enameled wire.

[0039] 5. The guide head on the guide block is clamped in the guide long groove of the hollow screw, facilitating the up and down movement of the cam along the hollow screw.

[0040] 6. A number of balls are arranged at the mating part of the cam and the swing arm fixing plate, facilitating the cam to push the swing arm fixing plate to move up and down along the hollow screw, so that the shaping block pats and shapes the windings in sequence.

The patent protection scope of the present invention shall be defined by each of the claims for all equivalent technical solution scopes.
