[0035] The following will be combined with the attached Figure 2-6 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0036] The inventor of the present application discovered that the existing motor rotor cleaning device has low cleaning efficiency for the motor rotor during the cleaning process. For this reason, the present application mainly adopts the following motor rotor cleaning device to achieve the purpose of efficiently and comprehensively cleaning the motor rotor. The present application is further described in detail below.

[0037] The motor rotor cleaning device provided in the embodiment of the present application refers to Figure 2 and Figure 3, comprising a cleaning machine 1, a movable carrier 11 and a spraying system (not shown in the figure), wherein the movable carrier 11 can be moved into or out of the cleaning machine 1, and the spraying system is arranged in the cleaning machine 1 for spraying the outer surface of the motor rotor 100 on the movable carrier 11, and the cleaning device also comprises a cross brace assembly 2 and a cleaning assembly 3 arranged in the movable carrier 11. The cross brace assembly 2 comprises a mounting plate 21 and a cross brace roller 22 rotatably connected to the mounting plate 21, and at least two cross brace rollers 22 are arranged, and the two cross brace rollers 22 are used to support the motor rotor 100 and drive the motor rotor 100 to rotate with its own axis as the rotation axis; the cleaning assembly 3 comprises a cleaning disc 31 and a cleaning nozzle 32, wherein the cleaning disc 31 is arranged on the mounting plate 21, and the cleaning nozzle 32 is installed on the disc surface of the cleaning disc 31, and the outlet of the cleaning nozzle 32 faces the end surface of the motor rotor 100. Among them, multiple groups of cross-bracing components 2 and cleaning components 3 are arranged along the axial direction of the motor rotor 100, and adjacent motor rotors 100 are blocked by mounting plates 21 so that impurities flushed from the motor rotor 100 are blocked by the mounting plates 21 and settle.

[0038] Specifically, the movable carrier 11 can be a rail-type carrier. Before cleaning, the movable carrier 11 is moved to the outside of the cleaning machine 1, and the motor rotor 100 is placed in the movable carrier 11 manually or by a mechanical arm. After the motor rotor 100 is placed, the movable carrier 11 is moved into the cleaning machine 1, and the motor rotor 100 is cleaned by the spray system and the cleaning component 3. After cleaning, the movable carrier 11 is moved out of the cleaning machine 1, and the motor rotor 100 is transferred. The cleaning machine 1, the movable carrier 11 and the spray system are prior arts and are not described in detail here.

[0039] Reference Figure 3 In this embodiment, two cross-bracing rollers 22 are provided, each of which includes a roller body 221 and a roller 222. The roller body 221 extends in the horizontal direction and is rotatably connected to the mounting plate 21. The roller 222 is detachably sleeved on the outer periphery of the roller body 221. Specifically, the roller 222 can be provided with a structure of being separated in half and combined in half, so as to facilitate the rapid disassembly and assembly of the roller 222 and the roller body 221. The outer wall of the roller 222 abuts against the outer wall of the motor rotor 100. The radius of the roller 222 is adjustable, and the rollers 222 of different radius sizes can be replaced to adapt to motor rotors 100 of different sizes. In addition, when the radius of the roller 222 remains unchanged, the roller 222 can also be adapted to motor rotors 100 of different sizes within a small range.

[0040] In addition, in order to prevent the motor rotor 100 from axially moving during the cleaning process, a limit ring 223 is provided at the end of the roller 222 for limiting the axial movement of the motor rotor 100. The limit ring 223 can abut against the side edge of the motor rotor 100 and the limit ring 223 does not block the ventilation hole 102, so that the cleaning agent sprayed by the cleaning nozzle 32 can accurately flush and clean the ventilation hole 102.

[0041] The material of the roller 222 can be stainless steel or polyurethane to adapt to different materials of the motor rotor 100. For example, for an aluminum motor rotor 100, the polyurethane roller 222 can be used to avoid scratching the surface of the motor rotor 100; while for a steel motor rotor 100, the stainless steel roller 222 is more wear-resistant. In addition, in order to increase friction, the outer surface of the roller 222 can be provided with anti-skid patterns, so as to better drive the motor rotor 100 to rotate.

[0042] Reference Figure 4 and Figure 5 Preferably, the cleaning nozzle 32 includes a vent cleaning nozzle 321 and a center hole cleaning nozzle 322. The vent cleaning nozzle 321 is arranged opposite to the vent 102 of the motor rotor 100, and the center hole cleaning nozzle 322 is arranged opposite to the center hole 101 of the motor rotor 100. In a preferred embodiment, a plurality of vent cleaning nozzles 321 are arranged circumferentially with the cleaning disk 31 as the center, and the radius between the vent cleaning nozzle 321 and the cleaning disk 31 is equal to the radius between the vent 102 and the center of the motor rotor 100, so that when the motor rotor 100 is driven to rotate, the cleaning agent sprayed from the vent cleaning nozzle 321 can directly flow to the vent 102, thereby improving the cleaning efficiency and cleaning effect.

[0043] In a preferred embodiment, the emission direction of the center hole cleaning nozzle 322 is inclined toward the inner wall of the center hole 101. As the motor rotor 100 rotates, the center hole cleaning nozzle 322 can be used to fully flush and clean the inner wall of the center hole 101, thereby improving the cleaning effect of the center hole 101 of the motor rotor 100. For the method of adjusting the emission angle of the center hole cleaning nozzle 322, an angle adjustment knob can be set on the center hole cleaning nozzle 322, and the inclination angle of the center hole cleaning nozzle 322 can be adjusted by rotating the angle adjustment knob. Among them, the liquid inlet end of the cleaning nozzle 32 can be connected to the spray system through a hose.

[0044] In a preferred embodiment, a drying nozzle 4 is also installed on the disk surface of the cleaning disk 31, and the air inlet end of the drying nozzle 4 is connected to the hot air source, and the outlet of the drying nozzle 4 is also facing the end face of the motor rotor 100. Specifically, the drying nozzle 4 also includes a ventilation hole drying nozzle 41 and a center hole drying nozzle 42. The ventilation hole drying nozzle 41 is arranged in a plurality of directions around the cleaning disk 31. The radius between the ventilation hole drying nozzle 41 and the cleaning disk 31 is equal to the radius between the ventilation hole 102 and the center of the motor rotor 100. The ventilation hole drying nozzle 41 and the ventilation hole cleaning nozzle 321 are arranged at intervals. Preferably, the outlet direction of the center hole drying nozzle 42 is inclined toward the inner wall of the center hole 101. Therefore, after cleaning is completed, the present application solution can also be used to efficiently and effectively remove the residues remaining in the ventilation hole 102 and the center hole 101 and perform drying treatment, thereby improving the cleaning quality and cleaning efficiency of the motor rotor 100.

[0045] At the same time, the hot air sprayed from the drying nozzle 4 is also blocked by the mounting plate 21, so that the hot air flows radially to the outer surface of other motor rotors 100, thereby improving the drying efficiency of the outer surface of the motor rotor 100, and also reducing the impact of hot air directly scouring the cleaning nozzle 32 on the service life of the cleaning nozzle 32.

[0046] Reference Figure 4 and Figure 5 In a preferred embodiment, the height of the cleaning disc 31 is adjustable, and the radius of the cleaning nozzle 32 and the center of the cleaning disc 31 is adjustable, so that the motor rotor cleaning device can adapt to motor rotors 100 of different diameters, thereby improving the applicability and flexibility of the equipment.

[0047] Specifically, the cleaning disk 31 includes a fixed disk 311 and a rotating disk 312. The fixed disk 311 is slidably connected to the mounting plate 21 in the height direction, and a first locking member 313 is provided between the fixed disk 311 and the mounting plate 21. The vent cleaning nozzle 321 and the vent drying nozzle 41 are slidably connected to the fixed disk 311 in the radial direction, and the rotating disk 312 is coaxially rotatably connected to the fixed disk 311. The rotating disk 312 is provided with an adjustment hole 314 extending in an involute line, and the vent cleaning nozzle 321 and the vent drying nozzle 41 pass through the adjustment hole 314. A second locking member 315 is provided between the fixed disk 311 and the rotating disk 312. This design allows the position of the cleaning disk 31, the vent cleaning nozzle 321, and the vent drying nozzle 41 to be flexibly adjusted according to different models of motor rotors 100, thereby ensuring the maximum cleaning effect.

[0048] In this embodiment, the first locking member 313 is a first latch. After the fixed disk 311 is moved to a predetermined position, the first latch is passed through the mounting plate 21 and the fixed disk 311 to lock the position of the fixed disk 311. The second locking member 315 is a second latch. A plurality of holes are provided on the rotating disk 312 along the circumferential direction. After the rotating disk 312 rotates a certain angle, the latch is passed through the fixed disk 311 and through the corresponding holes to complete the locking between the fixed disk 311 and the rotating disk 312. The purpose of designing this embodiment is that motor rotors 100 of different sizes correspond to different positions of the cleaning disk 31, the cleaning nozzle 32 and the drying nozzle 4. When a certain motor rotor 100 needs to be replaced for cleaning, the positions of the cleaning disk 31, the cleaning nozzle 32 and the drying nozzle 4 can be quickly adjusted to improve the adjustment efficiency. In other embodiments, the first locking member 313 and the second locking member 315 can also be locking bolts, magnetic locking members, etc.

[0049] Reference Figure 6 In a preferred embodiment, multiple groups of cross-bracing assemblies 2 and cleaning assemblies 3 are arranged along the axial direction of the motor rotor 100, the cross-bracing rollers 22 arranged along the axial direction of the motor rotor 100 are fixedly connected, and the cross-bracing rollers 22 arranged along the radial direction of the motor rotor 100 are driven by the same driving assembly 5.

[0050] The driving assembly 5 includes a transmission gear 51, a driving chain 52 and a driving member 53. The transmission gear 51 is fixed to one end of the horizontal support roller 22. The driving chain 52 is meshed with a plurality of transmission gears 51. The driving member 53 is used to drive the driving chain 52 to rotate. Optionally, the driving member 53 can be a motor group, which drives the driving chain 52 to rotate. Optionally, a waterproof shell (not shown in the figure) can be set around the outer periphery of the driving assembly 5 to extend its service life.

[0051] The implementation principle of this embodiment is as follows: the horizontal support roller 22 drives the motor rotor 100 to rotate, and the spray system can fully clean the outer surface of the motor rotor 100, solving the problem that it is difficult to clean the contact part between the motor rotor 100 and the support when the motor rotor 100 is placed still; at the same time, due to the rotation of the motor rotor 100, the cleaning agent sprayed by the cleaning nozzle 32 can quickly and fully flush all the ventilation holes 102 and the center hole 101 of the motor rotor 100 along the axial direction, improve the flushing efficiency, and then improve the cleaning efficiency; in addition, the impurities flushed out from the ventilation holes 102 and the center hole 101 can be blocked by the mounting plate 21 and quickly settled, solving the problem that the flushed impurities are easily transferred to other motor rotors 100. In addition, after cleaning, the drying nozzle 4 can also be used to quickly dry the ventilation holes 102 and the center hole 101. Therefore, the present application scheme can efficiently clean the ventilation holes 102 and the center hole 101 of multiple motor rotors 100, with high cleaning efficiency and low cost compared to ultrasonic cleaning. In addition, the present application scheme can also clean motor rotors that are being maintained and replaced, and has a wide range of applications.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
