The assembly fixing assembly 7 is connected to the drive end of the drive assembly 3. The housing fixture 5 is used to fix the motor housing, and the assembly fixing assembly 7 is used to fix the motor shaft, on which the motor windings are mounted. The drive assembly 3 is used to drive the assembly fixing assembly 7 to slide along the assembly guide element 6, so as to move the shaft toward the motor housing and assemble the windings into the motor housing. In this embodiment, the rotating shaft and winding are first assembled, and then placed on the assembly fixing component 7. The outer casing is placed on the outer casing fixture 5. During assembly, the assembly fixing component 7 is driven by the drive component 3 to move towards the outer casing fixture 5 to assemble the winding and the outer casing, thereby realizing the automatic assembly of the stator and rotor of the motor. This solves the problems of low assembly efficiency and difficulty in controlling accuracy of existing stator and rotor assembly methods.

[0028] The assembly guide element 6 of this invention ensures the stability and accuracy of the assembly fixing component 7 during movement. This effectively avoids positioning deviations that may occur in traditional manual assembly, guaranteeing precise alignment between the shaft and the motor housing. Precise assembly positioning ensures stable motor performance, reduces failure rates, and contributes to improving the overall quality and reliability of the product.

The crossbeam plates 42, as a key component connecting the two support side plates 41, are supported on both sides of the support side plates 41, forming a stable and reliable support plane. This allows the housing fixture 5 to be securely mounted on the crossbeam plates 42, further ensuring the positional accuracy and stability during stator and rotor assembly. Furthermore, the support assembly 4 has a compact structure and reasonable layout, optimizing the working space of the motor stator and rotor assembly equipment, making assembly operations more convenient and efficient.

The first reinforcing rib 411 is used to connect the supporting side plate 41 to the workbench 2, and the second reinforcing rib 412 is used to connect the supporting side plate 41 to the crossbeam plate 42. In this embodiment, the first reinforcing rib 411 effectively enhances the connection stability between the supporting side plate 41 and the workbench 2. This not only improves the overall load-bearing capacity of the equipment but also ensures that the connection between the supporting side plate 41 and the workbench 2 remains stable and reliable even under large assembly pressure or vibration during operation, thereby guaranteeing the accuracy and safety of the motor stator and rotor assembly operation. The setting of the second reinforcing rib 412 further enhances the connection strength between the supporting side plate 41 and the crossbeam plate 42.

This characteristic is crucial for the alignment and assembly accuracy of various components during the motor stator and rotor assembly process, effectively improving the accuracy and reliability of the assembly. Secondly, the sliding cooperation between the guide slider 62 and the linear slide rail 61 enables the flexible movement of the assembly fixing assembly 7 on the equipment. This flexibility not only allows the operator to adjust the assembly position according to actual needs but also significantly improves assembly efficiency and shortens the production cycle.

[0035] See Figure 6 As shown, the assembly and fixing assembly 7 includes a drive connecting frame 71, a shaft fixing seat 72, and a shaft clamping element 73. One side of the drive connecting frame 71 is connected to the assembly guide element 6, and the drive connecting frame 71 is connected to the drive end of the drive assembly 3. The shaft fixing seat 72 is disposed on the drive connecting frame 71 and faces the housing fixture 5.
