[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figures 1-4 As shown, a turbine maintenance tool for a bell spray gun includes a support 100 for removing the drive wheel 2. The support 100 is provided with a support disk 110. The support disk 110 is recessed in the upper end surface of the support 100, so that the upper part of the support 100 forms a disc-shaped structure with an annular stop 120. The inner diameter of the annular stop 120 is set corresponding to the diameter size of the bottom of the turbine. It also includes a push rod 130 for ejecting the drive wheel 2. The push rod 130 is provided with an ejection head 131 corresponding to the center hole of the turbine rotor 5. The ejection head 131 can be inserted into the center hole of the turbine rotor 5 to eject the drive wheel 2 inside the stator 1. Preferably, a stopper 132 is provided on the push rod 130 corresponding to the ejection head 131. The diameter of the stopper 132 is larger than the diameter of the center hole of the rotor 5 to limit the overtravel of the ejection head 131 and ensure safe operation.

[0024] When disassembling, if Figure 3 As shown, first remove the turbine bottom deflector 3, and place the turbine in the support disk 110. The annular stop 120 on the support 100 forms a limiting effect on the bottom of the turbine, ensuring the stability of the turbine placement. At this time, hold the push rod 130 so that the ejector head 131 penetrates the center hole of the rotor 5 into the interior of the stator 1, and pushes the drive wheel 2 downward to separate it from the stator 1. During the pushing process, a rubber hammer can be used to hammer it, saving time and effort. During the downward movement of the push rod 130, the stop platform 132 will stop outside the center hole of the rotor 5, realizing the travel limit of the push rod 130, avoiding the problem of damage to components caused by the over-travel of the ejector head 131, and ensuring safe operation.

[0025] As a preferred embodiment, Figure 4 As shown, the maintenance tool also includes a splitting device 200 for separating the turbine rotor 5 and the stator 1. The splitting device 200 includes a rotor wrench 210 and a stator wrench 220 hinged in the horizontal direction. The rotor wrench 210 and the stator wrench 220 are respectively provided with a rotor sleeve hole 211 and a stator sleeve hole 221. The aperture of the rotor sleeve hole 211 is set corresponding to the outer diameter of the rotor 5, and the aperture of the stator sleeve hole 221 is set corresponding to the outer diameter of the stator 1.

[0026] When the turbine rotor 5 is disassembled, the stator wrench 220 is sleeved on the stator 1 through the stator sleeve hole 221, and the rotor wrench 210 is sleeved on the rotor 5 through the rotor sleeve hole 211. The stator wrench 220 and the rotor wrench 210 are pulled to rotate relative to each other with the hinge point as the axis. At this time, the rotor sleeve hole will produce a horizontal displacement relative to the stator sleeve hole 221, thereby pushing the rotor 5 to radially translate relative to the stator 1, and finally smoothly separate from the stator 1, completing the separation of the rotor 5 and the stator 1.

[0027] This embodiment improves the traditional disassembly process that requires two people to cooperate in strong disassembly, reduces labor intensity, solves the problem that the rotor 5 and the stator 1 are extremely difficult to control under strong magnetic effects, effectively avoids violent collisions between components, and reduces the risk of accidental damage to components.

[0028] To facilitate turbine assembly, Figure 3 As shown, the bottom of the support 100 is provided with an assembly seat 140 for mounting the drive wheel 2. The outer diameter of the assembly seat 140 is smaller than the inner diameter of the stator 1, so that the stator 1 can be mounted on it. A support platform 150 is provided on the assembly seat 140 corresponding to the bottom of the drive wheel 2. The height of the support platform 150 corresponds to the blades at the bottom of the drive wheel 2 to support the blades from the assembly seat 140 and prevent them from being damaged.

[0029] During assembly, the support 100 is flipped so that the assembly base 140 faces upward. The drive wheel 2, which has been maintained, is then placed on the assembly base 140, with the bottom of the drive wheel 2 supported on the support platform 150 of the assembly base 140, so that the blades at the bottom of the drive wheel 2 do not contact the assembly base 140. The stator 1 is then inserted upside down into the support 100 and pressed downward, and the support platform 150 supports the drive wheel 2 and installs it into place. In this embodiment, the provision of the assembly base 140 facilitates quick assembly of the drive wheel 2 and the stator 1, and the provision of the support platform 150 effectively prevents damage to the blades of the drive wheel 2, ensuring safe assembly. During assembly and reassembly, the disassembly device 200 is opened to a certain angle so that the rotor sleeve hole 211 and the stator sleeve hole 221 are offset. Then, the rotor 5 that has been maintained is inserted into the rotor sleeve hole 211, and then the stator 1 is inserted into the stator sleeve hole 221. The rotor wrench 210 and the stator wrench 220 are slowly pushed to slowly bring the rotor 5 and the stator 1 closer horizontally. Finally, the rotor 5 and the stator 1 are stably aligned to complete the assembly.

[0030] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, any deformation made should be deemed to be protected by the present invention.
