Description

Technical Field

[0001] This utility model relates to the field of motor rotor insulation treatment technology, specifically to a motor rotor insulation treatment device. Background Technology

[0002] In layman's terms, the motor rotor is the rotating part of 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 divided into motor rotors and generator rotors. There are two types of motor rotors: internal rotor rotation and external rotor rotation. In the internal rotor rotation type, the core in the middle of the motor is the rotating body, outputting torque or receiving energy. In the external rotor rotation type, the outer body of the motor is the rotating body. Different types facilitate applications in various situations.

[0003] A search revealed a Chinese patent with publication number CN220107796U that discloses an insulation treatment device for motor rotors. The key technical point of this device is that it solves the problem that the cylindrical shape of the motor rotor leads to insufficient stability in fixing the motor rotor in Tianyou's technology, and the motor rotor is prone to falling off the surface of the clamp during operation, thus affecting the insulation treatment effect of the motor rotor.

[0004] However, in the above-mentioned solution, it was found that when the rotor is sprayed, excess insulating varnish drips into the working box below, and there is a lack of a structure to collect the insulating varnish, resulting in waste of the insulating varnish. In order to solve the problem of the lack of a structure to collect the insulating varnish in the prior art, which leads to waste of the insulating varnish, this application proposes to set up components such as guide plates, so that the excess insulating varnish can be collected into the collection box through the guide plates, and then returned to the storage box through the pump body and the pipeline. This achieves the effect of collecting and reusing the excess insulating varnish generated during the spraying process, preventing waste of the insulating varnish. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The aforementioned background technology addresses the shortcomings and defects of existing technologies, such as the lack of a structure for collecting insulating varnish, which leads to waste of the insulating varnish.

[0006] This utility model discloses an electric motor rotor insulation treatment device, including a mounting frame. Two baffles and two guide plates are fixedly connected to the upper surface of the mounting frame. The outer surface of each guide plate is fixedly connected to the outer surface of the corresponding baffle. A collection box is fixedly connected to the bottom surface of the mounting frame.

[0011] Furthermore, a threaded rod is rotatably connected to the inner wall of the protective shell, a push rod is threadedly connected to the outer surface of the threaded rod, and a limit member is fixedly connected to the outer surface of the push rod.

[0012] Furthermore, a guide rod is fixedly connected to the right side of the limiting member, and the outer surface of the guide rod is slidably connected to the inner wall of the protective shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a guide plate, a collection box, a first pump body, a first pipe, a second pump body, and nozzles, facilitates the extraction and spraying of insulating varnish from the storage box by setting up the second pump body, the second pipe, and the equidistantly arranged nozzles. The multiple nozzles achieve uniform spraying of the rotor. Excess insulating varnish drips onto the surface of the lower guide plate and is guided by the guide plate to the collection box below. The first pump body and the first pipe facilitate the extraction of insulating varnish from the collection box. The top of the first pipe is connected to the storage box, so that the insulating varnish can flow back into the storage box. This facilitates the collection and reuse of excess insulating varnish generated during the spraying process, preventing waste of insulating varnish.

[0015] 2. This utility model incorporates components such as gear one, gear two, a threaded rod, a push rod, a limiting component, and a guide rod. A three-jaw self-centering chuck is positioned at the right end of the mounting rod to clamp one end of the rotor, accommodating rotors of different sizes. A threaded rod and a push rod are located on the right side of the rotor. Rotating the threaded rod causes the push rod to move under the influence of the limiting component and the guide rod, bringing the left end of the push rod into contact with the right end of the rotor, thus clamping the rotor. At this point, a motor drives gear one to rotate, and the connection between gear one and gear two causes the three-jaw self-centering chuck to rotate, thereby driving the rotor to rotate and achieving a rotating spraying effect, which improves the uniformity of the spraying.

The rotation of the gear 16 can achieve the rotation of the gear 2 17.

[0029] Combination Figure 2 and Figure 4A mounting rod 18 is fixedly connected to the inner wall of gear 2 17. The mounting rod 18 is set on the inner wall of gear 2 17 and is fixedly connected. When gear 2 17 rotates, the mounting rod 18 can rotate. The left end of the mounting rod 18 is rotatably connected to the right side of the mounting plate 14 and is rotatably connected to the right side of the mounting plate 14 to achieve the limiting effect of the mounting rod 18. A three-jaw self-centering chuck 19 is fixedly installed on the right end of the mounting rod 18.

When the mounting rod 18 rotates, the three-jaw self-centering chuck 19 rotates with it, thereby making the rotor rotate. In conjunction with the spray nozzle 10 above, the uniformity of spraying is improved.

[0030] In a preferred embodiment, a threaded rod 20 is rotatably connected to the inner wall of the protective shell 12. The threaded rod 20 is installed on the inner wall of the protective shell 12 and configured as a rotatable connection to limit the movement of the threaded rod 20. A push rod 21 is threadedly connected to the outer surface of the threaded rod 20 and configured as a threaded connection.

[0031] In this embodiment, a guide rod 23 is fixedly connected to the right side of the limiting member 22. The guide rod 23 is installed on the right side of the limiting member 22 to achieve the positioning and installation effect of the guide rod 23.

The guide rod 23 is connected to the protective shell 12 in a sliding connection to limit the guide rod 23, thereby limiting the limiting member 22 and the top rod 21. This ensures that the top rod 21 can only move laterally under the action of the threaded rod 20 and will not rotate.

[0032] The implementation principle is as follows: One end of the rotor is clamped by the three-jaw self-centering chuck 19. At this time, the threaded rod 20 is rotated, causing the top rod 21, the limiting member 22 and the guide rod 23 to move laterally, thus tightening the right end of the rotor. The motor 15 is started to drive the gear 16 to rotate, which in turn drives the gear 17 to rotate. The gear 17 drives the mounting rod 18 and the three-jaw self-centering chuck 19 to rotate, thereby driving the rotor to rotate. The insulating varnish inside the storage tank 7 is extracted through the pump body 2 8 and the pipe 2 9, and then sprayed through multiple nozzles 10. The rotation of the rotor achieves uniform spraying. Excess insulating varnish falls onto the surface of the lower guide plate 3, which guides the excess insulating varnish to the lower collection tank 4. The insulating varnish inside the collection tank 4 is extracted through the pump body 1 5 and the pipe 1 6, and then returned to the storage tank 7 through the pipe 1 6. This facilitates the collection and reuse of excess insulating varnish generated during the spraying process, preventing waste of insulating varnish.
