[0036] First Embodiment

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an auxiliary machine disassembly and assembly tooling provided by this utility model; Figure 2 for Figure 1 The diagram shown is a first-person perspective three-dimensional structural schematic of the disassembly and assembly tooling; Figure 3 for Figure 1 The diagram shows a three-dimensional structure of the disassembly and assembly tool from a second-view perspective; Figure 4 for Figure 1 The diagram shows a cross-sectional view of the disassembly and assembly fixture. An auxiliary machine disassembly and assembly fixture includes:

[0038] 1. Base, 2. Multiple first pullers, 3. Pull plate, 4. Multiple limit sleeves, 5. Second puller, 6. Housing, 7. Multiple movable rods, 10. Non-drive end bearing extension sleeve, 11. Spacer ring, 12. Drive end bearing extension sleeve and 8. Connecting shaft;

[0039] Multiple first pullers 2 are disposed on the surface of the base 1;

[0040] The pull plate 3 is disposed between the plurality of first pullers 2;

[0041] The second puller 5 is positioned at the center of the pull plate 3;

[0042] The housing 6 is connected to one end of the second puller 5;

[0043] Multiple movable rods 7 are respectively connected to the bottom of the housing 6, and push plates 9 are connected between the multiple movable rods 7;

[0044] The non-drive end bearing extension sleeve 10, the spacer ring 11, and the drive end bearing extension sleeve 12 are respectively disposed below the base 1;

[0045] The docking shaft 8 is disposed between the non-drive end bearing extension sleeve 10, the spacer ring 11, and the drive end bearing extension sleeve 12.

[0046] A thrust ball bearing 15 is installed inside the housing 6.

[0047] The plurality of limiting sleeves 4 are respectively disposed at one end of the plurality of first pullers 2.

[0048] The other end of the first puller 2 is provided with a threaded sleeve 13.

[0049] The fan blades or spacers to be disassembled are fixed to the corresponding positions of the spacers 11 below the base 1 via the docking shaft 8, ensuring that the parts and the tooling are coaxial and avoiding force deviation caused by eccentricity during disassembly.

[0050] By rotating the threaded sleeve 13 at the end of the first puller 2, the length of the puller is adjusted so that the pull plate 3 fits tightly against the end face of the part to be disassembled. Multiple first pullers 2 are evenly distributed on the surface of the base 1, which can transmit uniform radial tension to the pull plate 3, solving the problem of part deformation caused by single-point force in traditional hand tools.

[0051] The limiting sleeve 4 at one end of the first puller 2 will limit the maximum extension of the puller to prevent excessive pulling force from exceeding the component's bearing limit and to ensure the safety of the disassembly process.

[0052] The drive end bearing to be press-fitted is fitted into the drive end bearing extension sleeve 12, and aligned with the auxiliary machine mounting position via the docking shaft 8. The extension sleeve can be adapted to bearings of different specifications without the need to replace the main tooling body.

[0053] The second puller 5 at the center of the pull plate 3 provides axial thrust, which is transmitted to the movable rod 7 through the housing 6; the thrust ball bearing 15 inside the housing 6 reduces transmission friction, making the thrust smoother and preventing the bearing from tilting due to jamming.

[0054] The movable rod 7 drives the push plate 9 to move down synchronously. The push plate 9 makes parallel contact with the bearing end face, and distributes the thrust evenly on the outer ring of the bearing, so as to realize the bearing is accurately pressed in along the axial direction, replacing the traditional manual hammering and pressing, and reducing the risk of bearing damage.

[0055] By replacing the non-drive end bearing extension sleeve 10, the tooling can similarly complete the press-fitting operation of the non-drive end bearing. The principle is the same as that of the drive end bearing press-fitting. Simply match the bearing to be press-fitted with the non-drive end bearing extension sleeve 10, position it through the docking shaft 8, and then the second puller 5 drives the push plate 9 to complete the press-fitting, further expanding the applicability of the tooling.

[0056] Compared with related technologies, the auxiliary machine disassembly and assembly tooling provided by this utility model has the following beneficial effects:

[0057] This utility model provides an auxiliary machine disassembly and assembly fixture. The base 1 provides stable support for the overall fixture. Multiple first pullers 2 are evenly distributed on the surface of the base 1 and work with pull plates 3 to form a uniform pulling force on the auxiliary machine components, avoiding excessive local force that could cause component deformation and improving the stability and safety of the disassembly process.

[0058] The structure of the second puller 5, housing 6, multiple movable rods 7 and push plate 9: The second puller 5 is located at the center of the pull plate 3. It can drive the movable rods 7 and push plate 9 through the housing 6 to achieve axial thrust output. It is suitable for press-fitting of components such as drive end bearings, replacing manual press-fitting and improving press-fitting accuracy and efficiency.

[0059] The limiting sleeve 4 is set at one end of the first puller 2, which can accurately limit the extension stroke of the puller, prevent the pulling force from exceeding the component's bearing capacity, and further ensure the integrity of the component during disassembly and assembly.

[0060] The non-drive end bearing extension sleeve 10, the drive end bearing extension sleeve 12, and the docking shaft 8 can be adapted to bearings of different specifications. The docking shaft is used to connect each extension sleeve to the corresponding auxiliary machine component, enabling targeted disassembly and assembly of different components of the non-drive end bearing and the drive end bearing, improving the versatility and adaptability of the tooling, and reducing the frequency of tool replacement.
