Description

Technical Field

[0002] The three-phase asynchronous motor is a type of induction motor. It is a type of motor that is powered by simultaneously connecting to a 380V three-phase alternating current (with a phase difference of 120 degrees). Because the rotor and stator rotating magnetic fields of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor.

[0003] The three-phase motor is mainly composed of a stator, a rotor, a power supply and a control device. The rotor will have a beautiful metallic color after production, but if the environment is humid or it is left for too long, obvious rust will appear on the rotor surface, which will not only affect the performance of the rotor but also the motor performance. Therefore, it is necessary to apply anti-rust paint on the surface of the rotor. The spraying method is costly and manual safety protection is required. If manual application is used, the efficiency will also be reduced. Therefore, it is necessary to design a rotor anti-rust paint application device for a three-phase motor, which automatically applies anti-rust paint to the rotor surface instead of manually, effectively improving the anti-rust paint application efficiency of the rotor while avoiding splashing of anti-rust paint.

[0026] Working principle: When the utility model is used, the user first moves the third slide 24 to the right on the top of the guide rail 21, and then sets the left end of the three-phase motor rotor 3 in the inner cavity of the second slide 23, so that the left end of the three-phase motor rotor 3 is between the two arc-shaped rubber sleeves 13, and then moves the third slide 24 to the left, so that Figure 1The right end of the three-phase motor rotor 3 is in the inner cavity of the third slide 24, and then the motor 2 9 is operated, so that the clamping plate 8 located on the upper side moves downward on the surface of the threaded column 10 and the guide rod 11, and then the two arc-shaped rubber sleeves 13 clamp and limit the three-phase motor rotor 3, and then the valve 19 is opened, so that the anti-rust paint in the inner cavity of the anti-rust paint container 16 passes through the inner cavity of the discharge pipe 17 to the bottom end of the brush head 18 to apply the surface of the three-phase motor rotor 3. At this time, the first slide 22, the second slide 23 and the third slide 24 move synchronously to the right at the top of the guide rail 21 , so that the brush head 18 is applied on the surface of the three-phase motor rotor 3 from the front to the left, until it reaches the rightmost side of the three-phase motor rotor 3. At this time, the motor 1 5 is running, driving the rotating column 6 to rotate inside the first slide 22, and then driving the three-phase motor rotor 3 to rotate between the second slide 23 and the third slide 24. When the three-phase motor rotor 3 is the surface to be coated with anti-rust paint, the motor 1 5 stops. At this time, the first slide 22, the second slide 23, and the third slide 24 move synchronously to the left on the top of the guide rail 21, and the anti-rust paint is applied to the three-phase motor rotor 3 in this way. The above-mentioned slide rail assembly 2 is a prior art, so it is not elaborated in detail, and the operation and stop of the motor 1 5, the motor 2 9 and the valve 19 can be programmed to make the coating of the three-phase motor rotor 3 more accurate, so as to effectively improve the anti-rust paint coating efficiency of the rotor and avoid the anti-rust paint splashing everywhere.

[0027] In summary, the rotor anti-rust paint coating device of the three-phase motor, through the setting of the slide rail assembly 2, enables the three-phase motor rotor 3 to be placed and moved, through the coordinated use of the mounting plate 7, the clamping plate 8, the motor two 9 and the threaded column 10, the three-phase motor rotor 3 is limited and clamped, through the coordinated use of the motor one 5 and the rotating column 6, the three-phase motor rotor 3 is rotated, and through the coordinated use of the mounting bracket 15, the anti-rust paint container 16, the discharge pipe 17 and the brush head 18, the anti-rust paint is coated on the surface of the three-phase motor rotor 3, which can effectively improve the anti-rust paint coating efficiency of the rotor while avoiding the anti-rust paint from splashing everywhere.
