[0050] The jacking closure mechanism 2 is fixedly mounted on the mounting platform 1 and is located below the mounting platform 1. The jacking closure mechanism 2 is provided with a lifting drive rod 22. The jacking closure mechanism 2 is adapted to drive the lifting drive rod 22 to pass through the through hole of the mounting platform 1 and extend upward.

[0051] The mounting seat 3 is movably arranged on the mounting platform 1. The mounting seat 3 is connected to the lifting drive rod 22 of the jacking mechanism 2. The mounting seat 3 is provided with a loading portion suitable for accommodating and supporting the bearing rotor assembly;

[0052] The lower mounting support frame 4 is fixedly arranged on the mounting platform 1, and an assembly space is formed between the lower mounting support frame 4 and the mounting platform 1;

[0053] The lower closing installation mechanism 5 is installed on the lower closing installation support frame 4. The lower closing installation mechanism 5 is provided with a clamping assembly 53, which is suitable for loading the upper cover shaft assembly;

[0054] Among them, the lifting upper closing mechanism 2 and the lower closing installation mechanism 5 are arranged opposite to each other in the vertical direction. When the lifting upper closing mechanism 2 drives the bearing rotor assembly to move upward through the mounting seat 3, the lower closing installation mechanism 5 is suitable for driving the upper cover shaft assembly to move downward and assemble the bearing rotor assembly and the upper cover shaft assembly in the assembly space.

[0055] In this embodiment, if Figure 1 and Figure 4-5 As shown, the upper lifting mechanism 2 drives the bearing rotor assembly on the mounting seat 3 upward via the lifting drive rod 22. Simultaneously, the lower closing mounting mechanism 5 drives the upper cover shaft assembly downward via the clamping assembly 53. The two are docked and assembled within the assembly space, thus avoiding the errors that may occur in traditional manual operations, greatly improving assembly efficiency and quality, and reducing damage to the bearings during the installation process.

[0056] Specifically, such as Figure 1 As shown, the motor-bearing assembly device further includes a linear motion mechanism 6, which is mounted on the mounting platform 1;

[0057] The mounting seat 3 is arranged on the linear movement mechanism 6;

[0058] The linear movement mechanism 6 is suitable for driving the mounting seat 3 to move horizontally along the horizontal plane of the mounting platform 1 .

[0059] Specifically, such as Figure 1-2 As shown, the linear motion mechanism 6 may have the following structure, including:

[0060] Two guide rails 61, the guide rails 61 are fixed on the mounting platform 1;

[0061] Two sliders 62, the sliders 62 are slidably engaged with the corresponding guide rails 61;

[0062] The mounting seat 3 is fixed on the slider 62;

[0063] The telescopic drive mechanism 63 is mounted on the mounting platform 1 and is provided with a telescopic end connected to the mounting base 3;

[0064] The telescopic driving mechanism 63 is suitable for driving the mounting seat 3 to move along the guide rail 61 .

[0065] Specifically, such as Figure 2 As shown, the telescopic drive mechanism 63 is a cylinder.

[0066] In this embodiment, if Figure 1-2 As shown, the linear motion mechanism 6 enables the mounting seat 3 to move smoothly. The sliding fit of the two sliders 62 and the guide rail 61 not only reduces friction but also improves the smoothness of movement. The mounting seat 3 is fixed to the sliders 62, allowing the mounting seat 3 to move stably along the guide rail 61. The telescopic end of the telescopic drive mechanism 63 is connected to the mounting seat 3 and is responsible for providing the power for movement. During use, the linear motion mechanism 6 has a starting position and an ending position. At the starting position, the completed assembly is removed from the mounting seat 3 and the bearing rotor assembly is placed. The linear motion mechanism 6 is activated and moves to the ending position to start assembly. After assembly is completed, it is activated again and moves to the starting position, and the cycle repeats.

[0067] In some embodiments, the number of guide rails 61 and sliders 62 is not limited to two and can be set according to specific needs.

[0068] Specifically, such as Figure 1-2 and Figure 5 As shown, the mounting base 3 may have the following structure, including:

[0069] A sliding fixing assembly 31, the sliding fixing assembly 31 is mounted on the linear moving mechanism 6;

[0070] A disengagement component 32 , the disengagement component 32 being movably disposed on the sliding fixing component 31 ;

[0071] The loading portion is provided on the disengagement assembly 32;

[0072] The telescopic driving mechanism 63 is connected to the detaching assembly 32 , and the telescopic driving mechanism 63 is suitable for driving the detaching assembly 32 to relatively detach from the sliding fixing assembly 31 .

[0073] In this embodiment, if Figure 1 and Figure 5 As shown, the disengagement assembly 32 is movably mounted on the sliding and fixing assembly 31 and is provided with a loading portion, allowing the bearing rotor assembly to quickly disengage from its fixed position when needed. A guide post is provided on the disengagement assembly 32, and a guide groove corresponding to the guide post is provided on the sliding and fixing assembly 31. The guide post and guide groove cooperate to improve the stability of movement.

[0074] Specifically, such as Figure 1 and Figure 4-5 As shown, the lifting and closing mechanism 2 can have the following structure, including:

[0075] A lifting drive mechanism 21 is fixed on the installation platform 1 and is provided with a driving end;

[0076] The lifting drive rod 22 is provided on the driving end of the lifting drive mechanism 21;

[0080] A mounting plate 52, the mounting plate 52 being fixedly connected to the drive output shaft;

[0081] The clamping assembly 53 is mounted on the mounting plate 52;

[0082] The vertical driving device 51 is suitable for driving the mounting plate 52 and the clamping assembly 53 to move in the vertical direction by driving the output shaft.

[0083] Specifically, such as Figure 4 As shown, the clamping assembly 53 is a pneumatic parallel clamp.

[0084] In this embodiment, if Figure 1 and Figure 3-4 As shown, the lower assembly mechanism 5 achieves precise positioning and stable movement of the upper cover shaft assembly. In actual operation, the vertical drive device 51 precisely controls the vertical movement of the mounting plate 52 and the clamping assembly 53, significantly improving assembly efficiency and quality. The clamping assembly 53 utilizes pneumatic parallel jaws, which can accommodate upper cover shaft assemblies of varying sizes and weights while also ensuring stability during the clamping process.

[0085] The specific model of the pneumatic parallel gripper can be SMCD's MHZ2-16D. The vertical drive device 51 can be a cylinder, and of course in some embodiments it can also be other components capable of driving telescopic movement.

[0086] In this embodiment, if Figure 1 and Figure 5As shown, the motor-bearing assembly device is also equipped with a barcode scanner. One is mounted below the mounting platform 1, with its barcode scanner aligned with the lift drive rod 22 of the upper lifting mechanism; the other is fixed to the lower lifting mounting support frame 4, with its barcode scanner facing the lower lifting mechanism 5. Four proximity sensors are also mounted on the mounting platform 1 and the lower lifting mounting support frame 4. Two of these sensors correspond to the installation start and end positions of the lower lifting mechanism 5, and the other two correspond to the movement start and end positions of the linear motion mechanism 6. These sensors are electrically connected to a controller. The controller is not only connected to the barcode scanner and proximity sensors, but also to the various drive components of the upper lifting mechanism 2, the lower lifting mechanism 5, and the linear motion mechanism 6. In actual operation, the controller controls the movement of the upper lifting mechanism 2 and the lower lifting mechanism 5 to ensure precise alignment of the bearing rotor assembly and the upper cover shaft assembly within the assembly space.
