[0002] A brushless motor is a type of motor, also known as a brushless DC motor or an electronically controlled speed motor. Compared to traditional brushed DC motors, brushless motors do not require brushes and slip rings for commutation, thus offering higher efficiency, longer lifespan, and lower maintenance requirements. The working principle of a brushless motor is to use an electronic controller to switch the current in real time, thereby driving the motor rotor to rotate. It typically consists of a stator and a rotor. The stator contains several coils that generate a rotating magnetic field through current switching. The rotor is equipped with permanent magnets or magnetic magnets, which rotate under the influence of the rotating magnetic field. The installation of motor bearings is a crucial step in the motor assembly process; its correctness and accuracy directly affect the motor's operating efficiency and lifespan. Currently, motor bearing installation is generally done manually, which is inefficient and difficult to control in terms of precision. Therefore, a new design is needed for existing motor bearing assembly methods. Utility Model Content

In this embodiment, the motor positioning groove 322 is used to fix the fixed end of the motor, and the winding positioning platform 341 is used to fix the winding of the motor. During assembly, the bearing is sleeved on the assembly positioning shaft 33, and then the drive assembly 5 drives the press-fit positioning shaft to move toward the assembly positioning shaft 33, pressing the bearing into the base 1. Assembly is convenient, assembly accuracy is high, and press-fit stability is good. This embodiment ensures the stability of the entire press-fitting process by firmly mounting the worktable 2 on the base 1. The support frame 4 is cleverly arranged around the outer periphery of the fixing fixture 3, providing solid support for the drive assembly 5 and effectively utilizing space, resulting in a compact and efficient overall structure. The fixed shaft seat 32 and positioning step 321 provided on the fixture base 31 provide precise axial and radial positioning for the assembly positioning shaft 33. The assembly positioning shaft 33 is located at the axis of the positioning step 321, ensuring the coaxiality of the bearing during installation and effectively preventing assembly deviations. In addition, the design of the winding positioning seat 34 not only provides stable support for the winding but also further improves the relative positional accuracy between the winding and the bearing through the cooperation of the motor positioning slot 322 and the winding positioning table 341, thereby ensuring the overall performance of the motor. The collaborative work of the drive assembly 5 and the press-fitting assembly 6 realizes automated press-fitting of the motor bearing.

[0026] The base 1 includes a base plate 11 and a control box 12. The control box 12 is mounted on the base plate 11, and the workbench 2 is mounted on the control box 12. Handle slots 121 are provided on both sides of the control box 12. Specifically, a control button 21 is provided on one side of the workbench 2. The control button 21 is used to control the drive assembly 5 to move the pressing assembly 6. In this embodiment, the base plate 11 serves as a stable foundation for the entire equipment, ensuring the stability and reliability of the equipment during operation. The control box 12 not only enables centralized control of the motor bearing pressing process but also greatly facilitates the handling and movement of the equipment by operators through its carefully designed handle slots 121 on both sides. The control button 21 on the workbench 2 allows operators to intuitively control the drive assembly 5, thereby driving the pressing assembly 6 to move precisely and efficiently, thus achieving accurate pressing of the motor bearing.

[0027] The support frame 4 includes a support plate 41 and a crossbeam 42. The support plate 41 is mounted on the workbench 2, and the crossbeam 42 is mounted on the top of the support plate 41. Two sets of support plates 41 are provided, with sensor light curtains 411 positioned opposite each other. Specifically, an inner support plate 22 is provided on the workbench 2 to support the crossbeam 42, and the drive assembly 5 is mounted on the crossbeam 42. In this embodiment, the support plates 41 are stably mounted on the workbench 2, providing a solid foundation for the entire pressing process and ensuring operational stability and accuracy. The sensor light curtains 411, with the two sets of support plates 41 positioned opposite each other, can effectively monitor the workpiece position and status during the pressing process, achieving intelligent control and greatly improving production efficiency and safety. Furthermore, the specially designed inner support plate 22 on the workbench 2 not only enhances the support strength of the crossbeam 42 but also optimizes the stress distribution of the overall structure, allowing the pressing force to be transmitted evenly, reducing equipment vibration and noise, and extending service life. As a key component in the pressing operation, the crossbeam 42 is equipped with a drive assembly 5 that can precisely control the pressing force and displacement, achieving refined pressing operations and ensuring the installation accuracy and quality of the motor bearings.

[0028] The pressing assembly 6 includes a pressing slider 62 and a pressing sliding frame 63. The pressing slider 62 is mounted on the support frame 4, and the pressing sliding frame 63 is slidably mounted on the pressing slider 62. The pressing seat 61 is mounted on the pressing sliding frame 63, and one end of the pressing sliding frame 63 is connected to the drive assembly 5, which is a cylinder. In this embodiment, the ingenious combination of the pressing slider 62 and the pressing sliding frame 63 ensures stability and accuracy during the pressing process. The pressing slider 62 is mounted on the support frame 4, and the support frame 4 can be slidably mounted on the slider. This design makes the pressing action more flexible and can adapt to the pressing requirements of motor bearings of different sizes and specifications. Secondly, the pressing seat 61 is mounted on the pressing sliding frame 63, which not only optimizes the pressing path but also improves the pressing efficiency. The pressing seat 61 can directly act on the motor bearing, ensuring uniform transmission of pressing force and avoiding bearing damage or improper installation caused by uneven force. Furthermore, the drive assembly 5 uses a cylinder as its power source, which has the advantages of fast response speed and high control precision.

[0029] The press-fit base 61 has a chamfered bevel 612 at one end facing the assembly positioning shaft 33, and a press-fit ring 613 at the end of the chamfered bevel 612. The press-fit ring 613 is used for bearing press-fitting. The press-fit positioning hole 611 is centrally located on the press-fit ring 613, and a guide bevel 614 is provided at the end of the press-fit positioning hole 611. The positioning step 321 is located on the outer periphery of the assembly positioning shaft 33 and has a clearance groove 323. In this embodiment, the chamfered bevel 612 at the end of the press-fit base 61 facing the assembly positioning shaft 33 not only optimizes the guidance during the assembly process but also reduces the frictional resistance during assembly, allowing the bearing to enter the predetermined position more smoothly. The press-fit ring 613 at the end of the chamfered bevel 612, as a key component for bearing press-fitting, is designed to ensure the stability and uniform force distribution of the bearing during the press-fitting process, effectively avoiding deformation or damage to the bearing due to uneven force distribution. Meanwhile, the centrally located press-fit positioning hole 611 on the press-fit ring 613, and the guide slope 614 at the hole opening, further enhance the accuracy of bearing positioning, ensuring that the bearing can be accurately aligned with the assembly position. Furthermore, the clearance groove 323 on the positioning step 321 on the outer periphery of the assembly positioning shaft 33 provides necessary space compensation for bearing press-fitting, effectively preventing assembly interference problems caused by assembly tolerances. This not only improves assembly flexibility but also ensures that the bearing maintains a stable operating state after press-fitting.
