Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor winding, in particular to a winding device for motor rotor production. Background Art

[0002] Motor rotor: This is the rotating component in a motor. A motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. Motor rotors are classified as either motor rotors or generator rotors.

[0003] Motor rotors are categorized into two types: internal rotor and external rotor. In the internal rotor type, the motor's central core acts as the rotating body, outputting torque (for motors) or receiving energy (for generators). In the external rotor type, the motor's outer body acts as the rotating body. These different types facilitate various applications.

[0004] Existing patents, such as application number CN201920934612.6, disclose a winding device for producing motor rotors, comprising a base plate, a chute provided on the upper surface of the base plate, a support column movably connected to the interior of the chute, a cross plate fixedly connected to the top of the support column, a motor fixedly connected to the upper surface of the cross plate, a rotating shaft fixedly connected to the output end of the motor, a first bearing fixedly connected to the upper surface of the cross plate, a vertical rod fixedly connected to the interior of the first bearing, a coil fixedly connected to the outer surface of the vertical rod and the outer surface of the rotating shaft, a connecting belt movably connected between the two coils, and an eccentric wheel fixedly connected to the top of the vertical rod. This winding device for producing motor rotors has the advantage of high work quality.

[0005] Although the above patent solves the problem of derailment, the motor rotor is not directly wound on an axis during actual use. The rotor is composed of permanent magnets with a certain number of pole pairs embedded on the surface of the iron core or embedded inside the iron core. Therefore, the winding is complicated and not a simple winding. Manual winding is usually used, which is inefficient and cannot evenly wrap the wire around the rotor, resulting in derailment and other problems, which has the serious consequence of reducing the work quality.

A torsion spring 11 is installed in the movable hole 205. One end of the torsion spring 11 is connected to the inner wall of the movable hole 205, and the other end is connected to the limiting shaft 10. Specifically, the guide plate 201 clamps the upper and lower ends of the motor rotor through the torsion spring 11.

[0032] When the utility model is implemented, Figure 1 and Figure 2 As shown, a rotating winding mechanism 3 is installed on one side of the auxiliary guide device 2. The rotating winding mechanism 3 includes a driving motor 301 and a rotating shaft 302 output by the driving motor 301. The outer side of the rotating shaft 302 is fixedly connected to a wire tube 303. Specifically, the winding copper wire passes through the wire tube 303 and is connected to the motor rotor. The other end of the winding copper wire is a rotatable winding roller. When the driving motor 301 is working, it drives the rotating shaft 302 to rotate and drives the wire tube 303 to rotate at the same time. The winding copper wire is rotated and wound on the motor rotor through the auxiliary guide device 2.

A telescopic rod or screw mechanism is installed in the housing 4. The upper end of the stopper 5 defines a mounting hole 6 for inserting the motor rotor. The movable end of the telescopic rod or screw mechanism is connected to the stopper 5. The telescopic rod or screw mechanism drives the stopper 5 to slide under the guidance of a slide groove 7, thereby driving the motor rotor to move.

The wound copper wire is rotated and wound around the motor rotor through the auxiliary guide device 2. At the same time, the telescopic rod drives the motor rotor on the limit block 5 to move. Due to the operation of the telescopic rod, the two guide plates 201 are tightly attached to the upper and lower ends of the motor rotor, guiding the copper wire so that the copper wire can be evenly wound on the outer surface of the rotor, solving the problem of wire derailment caused by uneven winding, thereby achieving the purpose of improving work quality.

The guide plate 201 clamps the upper and lower ends of the motor rotor through the torsion spring 11. When the driving motor 301 is working, it drives the rotating shaft 302 to rotate and drives the wire tube 303 to rotate at the same time. The winding copper wire is rotated and wound on the motor rotor through the auxiliary guide device 2. At the same time, the telescopic rod drives the motor rotor on the limit block 5 to move. Due to the operation of the screw mechanism, the two guide plates 201 are tightly attached to the upper and lower ends of the motor rotor, guiding the copper wire so that the copper wire can be evenly wound on the outer surface of the rotor, solving the problem of wire derailment caused by uneven winding, thereby achieving the purpose of improving work quality.
