TECHNICAL FIELD
[0001] The present application belongs to the technical field of motor maintenance and repair, and particularly relates to a motor repair multifunctional all-in-one machine. BACKGROUND
[0002] Electric repair factories need to repair several thousand motors every year, some of which are high-voltage motor stator windings that need to be overhauled, and several hundred of which are wire-wound rotors that need to be overhauled or repaired. In the motor repair industry, motor stator windings are installed in motor stator cores, and when high-voltage motor stator windings are burned and need to be repaired, the stator windings need to be completely removed first. Wire-wound rotors need to be rewound with non-woven tape after being overhauled or repaired.
[0003] The high-voltage motor stator windings of electric repair factories are currently removed by the original manual removal method. For large high-voltage motors, due to the limited conditions, it is difficult to remove the stator windings, and the problems are that the removal period is long, it takes more than a week to remove the windings of a high-voltage motor by manual removal; the labor intensity is high, and the current high-voltage motor technology is mostly vacuum impregnation technology, the slot fill rate is high, the winding and the core are tightly attached, a specially made steel drill needs to be used to hit with a hammer, and the core is easily deformed during the removal process, a large amount of burrs are generated, the core deformation is difficult to repair, the burrs are not cleaned, ground short circuits are caused, and the service life of the repaired motor is also reduced. The labor cost is high due to the high labor intensity, 4 people need to rotate and hit with a hammer, and continuous operation for 7 days, resulting in high labor cost. This traditional method is highly destructive to the stator, wastes a lot of materials, and has safety hazards.
[0004] In addition, when the motor rotor winding is wound with non-woven tape, the existing technology is to rotate the rotor by manpower. According to the size of the rotor and the tension of the non-woven tape, 3-6 people are needed to complete the operation by rotating the rotor by manpower; the speed and force of manual rotation of the rotor are uneven, and the non-woven tape is unevenly stressed, which causes poor consistency, high rejection rate, affects the appearance quality, and has low winding efficiency, time-consuming and labor-intensive, and high labor intensity.
[0005] Some existing devices that can only remove the stator winding or wind the rotor have poor applicability, need to prepare multiple sets of devices with different diameters, cannot adapt to the extension shaft of the stator winding or the rotor shaft with different diameters and sizes, and are not easy to adjust the center alignment, and lack universality.
