[0042] The following combines with the attached drawings to illustrate the detailed implementation manners of the present utility model. Detailed implementation manners

[0044] As Figures 1 - 4 shown, this embodiment discloses a rotor disassembly tooling, which is mainly used for disassembling a rotor assembly with a tension connection, especially for disassembling an impeller and a shaft. This tooling is exquisitely designed and easy to operate, and can effectively separate the tightly connected impeller and shaft while avoiding damage to the components. This tooling mainly includes a mounting frame 3, an impeller disassembly ring 1, a driving mechanism, a shaft disassembly ring 2 and other key components.

[0045] As Figure 1 shown, the mounting frame 3 is the main structure of the entire tooling. It includes two parallel mounting tables, which are connected to each other through connecting parts to ensure a stable structure. Mounting holes located on the same vertical line are provided on the two mounting tables for mounting and positioning other components.

[0046] In this embodiment, the impeller assembly is the object to be disassembled. In this embodiment, the impeller assembly is also used as an object for elaboration. In the actual processing process, as long as the assembly conforms to the characteristics of the impeller, the disassembly tooling in this embodiment can be used for operation. The characteristics include two connected components, and a tension connection method is adopted between the two components, and through-holes are provided between the two components, and annular grooves are provided in the through-holes.

[0047] The impeller assembly includes an impeller 6 and a shaft 7 with a tension connection. The impeller 6 is close to the lower mounting table, and the impeller through-hole 61 on the impeller 6 is arranged opposite to the mounting hole for mounting and positioning.

[0048] The impeller disassembly ring 1 passes through the mounting hole provided on the lower mounting table and extends between the two mounting tables. The main function of this disassembly ring is to contact and fix the impeller for disassembly operations.

[0049] The driving mechanism is fixed to the upper mounting table, and its driving shaft passes through the mounting hole on the upper mounting table and docks with the shaft disassembly ring 2. The driving mechanism is used to provide the power required for disassembly, pushing the shaft disassembly ring 2 to move downward, thereby realizing the separation of the impeller and the shaft.

[0050] The shaft disassembly ring 2 is connected to the driving mechanism, and its outer edge is embedded in the impeller assembly for contacting and fixing the shaft so as to separate it from the impeller.

[0051] Both the impeller disassembly ring 1 and the shaft disassembly ring 2 adopt a splicing structure, including at least two load-bearing rings and connecting pins for connecting multiple load-bearing rings to form an integral structure. This splicing structure enables the disassembly ring to adapt to impellers and shafts of different sizes, improving the versatility of the tooling.

[0052] In this embodiment, the impeller disassembly ring 1 includes at least two first load-bearing rings 11, and multiple first load-bearing rings 11 are connected by first connecting pins 12. Multiple first connecting pins 12 are connected to multiple first load-bearing rings 11 to form a circular integral structure, which is convenient for fitting with the impeller through-hole 61 in the impeller 6, so that the annular protruding structure 112 is stuck in the impeller annular groove 62.

[0053] In this embodiment, as Figure 3 shown, the number of the first load-bearing rings 11 is two. In the actual working process, the number of the first load-bearing rings 11 is not limited, as long as it is greater than 1. However, the fewer the number, the simpler the operation process and the higher the stability.

[0054] In this embodiment, as Figure 4 shown, the shaft disassembly ring 2 includes at least two second load-bearing rings 21, and multiple second load-bearing rings 21 are connected by second connecting pins 22. Multiple second connecting pins 22 are connected to multiple second load-bearing rings 21 to form a circular integral structure, which is convenient for fitting with the shaft through-hole 71 in the shaft 7, so that the outer edge on the second load-bearing ring 21 is engaged in the shaft annular groove 72.

[0055] In this embodiment, the first connecting pin 12 includes a first connecting rod 121 and an outer edge provided at the end of the first connecting rod 121, and the second connecting pin 22 includes a second connecting rod 221 and an outer edge provided at the end of the second connecting rod 221.

[0056] In this embodiment, the impeller assembly adopts a layout with the impeller 6 below and the shaft 7 above. In the actual use process, if the orientations of the impeller 6 and the shaft 7 change, the positions of the impeller disassembly ring 1 and the shaft disassembly ring 2 need to be adjusted accordingly. Therefore, it can be arranged in any direction, not limited to the direction indicated in the drawings.

[0057] On a section of the side wall of the impeller disassembly ring 1 extending between the two mounting platforms, there is at least one annular convex structure 112 embedded in the impeller assembly. At the same time, on the outer walls of the impeller disassembly ring 1 and the shaft disassembly ring 2, there is a section of expanded outer edge for better contact and fixation of the impeller and the shaft.

[0058] In this embodiment, an impeller through-hole 61 and a shaft through-hole 71 are respectively provided in the impeller 6 and the shaft 7. Both through-holes are circular. In practical applications, the circular through-holes are used to connect the transmission shaft for transmission. And an impeller annular groove 62 and a shaft annular groove 72 are respectively provided in the impeller through-hole 61 and the shaft through-hole 71. The annular grooves are preset for the impeller assembly and are usually used for shaft sleeve structures such as sealing rings and oil seals. In this embodiment, by using the preset annular grooves on the impeller assembly, the axial limit fixation is realized, so as to achieve disassembly and assembly, improving the work efficiency.

[0059] In this embodiment, the impeller annular groove 62 on the impeller 6 is arranged in a matching manner with the annular convex structure 112, and the shaft annular groove 72 on the shaft 7 is arranged in a matching manner with the outer edge on the shaft disassembly ring 2. This matching design ensures that the disassembly ring can firmly fix the impeller and the shaft, while avoiding damage to the components during the disassembly process.

[0060] In this embodiment, the load-bearing ring is the basic unit constituting the disassembly ring. It includes a guiding member and an outer edge that is connected to one end of the guiding member and expands horizontally outwards. Both the guiding member and the outer edge are fan-shaped, and the angle of the fan shape is less than 160 degrees. This design enables the load-bearing rings to form a tight circular structure when spliced, ensuring that the load-bearing ring can smoothly pass through the mounting hole.

[0061] In this embodiment, the first load-bearing ring 11 includes a first guiding member 111 and a first outer edge. The diameter of the first outer edge is larger than the mounting hole for better contact and fixation of the impeller or the shaft; while the diameter of the first guiding member 11 is smaller than the mounting hole.

[0062] In this embodiment, the second load-bearing ring 21 includes a second guiding member 211 and a second outer edge. The diameter of the second outer edge is between the shaft through-hole 71 and the shaft annular groove 72, while the diameter of the second guiding member 211 is smaller than the diameter of the shaft through-hole 71.

[0063] In this embodiment, in order to further improve the overall stability of the impeller disassembly ring 1 and the shaft disassembly ring 2, a stepped groove is provided on the upper side wall of the outer edge of the load-bearing ring. An expanded outer edge is provided on the side wall of the connecting pin, and the outer edge of the connecting pin is arranged in the stepped groove of the outer edge of the load-bearing ring. This design enables the connecting pin to firmly connect multiple load-bearing rings together to form an overall disassembly ring structure.

[0064] Meanwhile, on the step groove of the first load-bearing ring 11 and the outer edge of the first connecting pin 12, there are connecting holes 122 that match each other. A fixing pin is connected to the connecting holes, further enhancing the structural strength of the disassembly ring.

[0065] In this embodiment, as Figure 1 shown, the driving mechanism is a hydraulic jack 4, which is a commonly used power device and can provide stable thrust. A pull rod 5 is provided on the hydraulic jack 4. The pull rod 5 extends between the two mounting platforms and is connected to the shaft disassembly ring 2. By the telescopic movement of the hydraulic jack 4, the shaft disassembly ring 2 can be pushed downward to realize the separation of the impeller and the shaft.

[0066] To facilitate the connection and disassembly of the shaft disassembly ring 2 and the pull rod 5, an external thread 212 is provided on the outer wall of the shaft disassembly ring 2, and an internal thread corresponding to the shaft disassembly ring 2 is provided on the pull rod 5. This threaded connection method is simple and reliable and convenient to operate.

[0067] The specific working principle in this embodiment is as follows:

[0068] In the initial state, before disassembly, first place the impeller assembly (including the impeller 6 and the shaft 7) on the lower mounting platform of the mounting frame 3, and ensure that the impeller through-hole 61 is oppositely arranged with the mounting hole. Then, pass a plurality of first load-bearing rings 11 through the mounting holes on the lower mounting platform, and make its annular convex structure 112 embed into the impeller annular groove 62 of the impeller 6. Then, by inserting the first connecting pin 12, a plurality of first load-bearing rings 11 are formed into an integral structure. At the same time, through the fixing pin, the first connecting pin 12 and the first load-bearing ring 11 are strengthened to fix the impeller 6.

[0069] Install the shaft disassembly ring 2. Similarly, then pass the shaft disassembly ring 2 through the mounting hole on the upper mounting platform, and make its outer edge embed into the shaft annular groove 72 of the shaft 7 to fix the shaft 7. At this time, the shaft disassembly ring 2 and the pull rod 5 of the driving mechanism are connected together by threads.

[0070] Start the driving mechanism, start the hydraulic jack 4, and make it push the pull rod 5 upward. Since the pull rod 5 is connected to the shaft disassembly ring 2, the shaft disassembly ring 2 will also move upward accordingly. Under the action of the shaft disassembly ring 2, the shaft 7 will gradually separate from the impeller 6.

[0071] The rotor disassembly tooling described in the present utility model has the following remarkable advantages and effects:

[0072] Strong versatility

[0073] Since the disassembly ring adopts a splicing structure and can be combined and adjusted according to impellers and shafts of different sizes, this tooling has strong versatility and is suitable for disassembling rotor components of various models.

[0075] The entire disassembly process only requires power provided by a hydraulic jack, without complex operation steps and professional skills, so it is simple and easy to operate.

[0077] The annular protrusion structure and outer edge design on the disassembly ring can firmly fix the impeller and shaft, while avoiding damage to the components during the disassembly process, protecting the integrity and service life of the components.

[0078] Improve efficiency

[0079] Compared with traditional disassembly methods, the rotor disassembly tooling described in the present utility model can complete the disassembly work more quickly and efficiently, improving work efficiency and maintenance speed.

[0080] In summary, the rotor disassembly tooling described in the present utility model has the advantages and effects of delicate structure, simple operation, strong versatility, protecting components, and improving efficiency.
