Description

Technical Field

[0001] This utility model relates to the field of motor production equipment technology, specifically to a motor rotor copper wire winding device. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In a circuit, an electric motor is represented by the letter M. Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. A generator is represented by the letter G in a circuit. Its main function is to convert mechanical energy into electrical energy.

[0003] In existing large rotors, copper wire winding is often performed using rotating equipment while manual winding and tracing are done. This method is time-consuming, labor-intensive, and inefficient. Furthermore, existing rotating equipment lacks necessary positioning structures when fixing the rotor to the rotating equipment, causing the stator to be inaccurately positioned at the rotation center. This results in eccentric rotor movement, posing a significant safety hazard. Moreover, after winding the copper wire on one side of the rotor, it is necessary to reload the rotor onto the rotating equipment to wind the copper wire on the other side of the stator.

[0004] Therefore, we have made improvements to this by proposing a copper wire winding device for motor rotors. Utility Model Content

When the rotor rotates once, that is, the copper wire winds around one side of the rotor once, the control panel controls the hydraulic cylinder to push the winding roller bracket according to the preset stroke, so that the copper wire adheres to the copper wire already wound on one side of the rotor and continues to wind. When the copper wire has wound the entire rotor, the winding roller bracket triggers the limit switch, and the hydraulic cylinder retracts the winding roller bracket according to the preset stroke to continue the winding action on the rotor. Through the limit switches on both sides of the inner cavity of the winding bracket and the hydraulic cylinder, the winding action on the rotor is repeated, eliminating the need for manual winding and winding, and realizing the automation of rotor winding.

[0050] The working principle of this utility model:

[0051] The rotor is fixed to the fixed component 2. The lower shaft of the rotor is fitted into the bushing 8 at the lower end of the rotating plate 4. Then, the screw nut 16 is tightened, and the bushings 8 at both ends of the rotating plate 4 are moved toward the middle of the rotating plate 4 through the screw 14 and the hinge plate 12. This allows the upper shaft of the rotor to be fitted into the bushing 8 at the lower end of the rotating plate 4, and the rotor to be located in the middle of the rotating plate 4. This prevents eccentric rotation when the rotating body 1 drives the rotor to rotate. The rotor shaft is fixed to the bushing 8 using the fixing bolt 9. After the winding on one side of the rotor is completed, the fixing bolt 9 is loosened. At this time, the rotor rotates between the two fixed components. There is no need to unload the rotor.

[0052] The front end of the copper wire is fixed to one side of the rotor through the winding groove 25 of the upper fixed roller 20 and the lower clamping roller 21. The rotating body 1 is started, and the rotating body 1 drives the rotor to rotate. The laser receiver 30 and the laser emitter 32 detect the number of rotor rotations, and the counter 33 records the number of rotor rotations and sends it to the control panel 34. When the rotor rotates once, that is, the copper wire winds around one side of the rotor once, the control panel 34 controls the hydraulic cylinder 23 to push the winding roller bracket 19 according to the preset stroke, so that the copper wire adheres to the copper wire already wound on one side of the rotor and continues to wind. When the copper wire winds the entire rotor, the winding roller bracket 19 triggers the limit switch 24, and the hydraulic cylinder 23 retracts the winding roller bracket 19 according to the preset stroke to continue the winding action on the rotor. The limit switches 24 on both sides of the inner cavity of the winding bracket 18 cooperate with the hydraulic cylinder 23 to reciprocate the winding action on the rotor.
