Description

Technical Field

[0001] This utility model relates to the field of motor installation technology, and in particular to a DC motor core assembly fixture. Background Technology

[0002] In the manufacturing process of DC motors, the precise assembly of the stator core and the motor housing is one of the key steps to ensure stable motor performance and high operating efficiency. As an important component of the motor's magnetic circuit, the positional accuracy of the stator core directly affects the motor's electromagnetic performance, noise level, and service life. Traditional methods for assembling the stator core and motor housing often involve manual placement combined with mechanical press-fitting.

[0003] Manual assembly often relies on the operator's experience and feel, making it difficult to accurately control the alignment of the iron core axis with the center of the housing, resulting in large assembly deviations and affecting the overall performance of the motor. In addition, during the placement and retrieval of materials, the hands are located below the hydraulic telescopic rod, and due to the lack of effective safety protection measures, the operator is easily injured. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a DC motor core assembly fixture. In actual use, this fixture effectively improves overall safety and ensures the overlap between the core axis and the center of the housing, thereby improving assembly quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A DC motor core assembly fixture includes a support plate; a placement and adjustment mechanism, the placement and adjustment mechanism including a first L-shaped frame fixedly connected to the upper end of the support plate, a second L-shaped frame fixedly connected to the upper end of the first L-shaped frame, a connecting shaft passing through the horizontal part of the first L-shaped frame, the connecting shaft being rotatably connected to the horizontal part of the first L-shaped frame, a first rotating disk fixedly connected to the lower end of the connecting shaft, two first placement openings symmetrically opened on the first rotating disk, a second rotating disk fixedly connected to the upper end of the connecting shaft, two second placement openings symmetrically opened on the second rotating disk; and a pressing mechanism for realizing the assembly operation.

[0008] Preferably, a drive motor is installed at the lower end of the support plate, and the output of the drive motor passes through the support plate and is fixedly connected to the lower end of the first rotating disk.

[0009] Preferably, the pressing mechanism includes a second L-shaped frame fixedly connected to the upper end of the first L-shaped frame, a hydraulic telescopic rod installed at the upper end of the horizontal part of the second L-shaped frame, the telescopic end of the hydraulic telescopic rod passing through the horizontal part of the second L-shaped frame and fixedly connected to a pressure plate.

[0010] Preferably, a guide rod is fixedly connected to the upper end of the pressure plate, and the upper end of the guide rod passes through the horizontal part of the second L-shaped frame and is slidably connected.

[0011] Preferably, a guide cylinder is fixedly connected to the lower end of the horizontal part of the first L-shaped frame, and a guide opening is provided on the horizontal part of the first L-shaped frame.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A DC motor core assembly fixture includes a support plate 1, and a plurality of support legs 2 are fixedly connected to the lower end of the support plate 1.

[0020] The system also includes a placement adjustment mechanism, which includes a first L-shaped frame 4 fixedly connected to the upper end of the support plate 1, a second L-shaped frame 5 fixedly connected to the upper end of the first L-shaped frame 4, a connecting shaft 10 passing through the horizontal part of the first L-shaped frame 4, the connecting shaft 10 being rotatably connected to the horizontal part of the first L-shaped frame 4, a first rotating disk 9 fixedly connected to the lower end of the connecting shaft 10, two first placement openings 12 symmetrically opened on the first rotating disk 9, a second rotating disk 11 fixedly connected to the upper end of the connecting shaft 10, two second placement openings 13 symmetrically opened on the second rotating disk 11, and a drive motor 3 installed at the lower end of the support plate 1. The output of the drive motor 3 passes through the support plate 1 and is fixedly connected to the lower end of the first rotating disk 9.

[0021] The assembly also includes a pressing mechanism for assembly operations. The pressing mechanism includes a second L-shaped frame 5 fixedly connected to the upper end of the first L-shaped frame 4. A hydraulic telescopic rod 6 is installed at the upper end of the horizontal part of the second L-shaped frame 5. The telescopic end of the hydraulic telescopic rod 6 passes through the horizontal part of the second L-shaped frame 5 and is fixedly connected to a pressure plate 7. A guide cylinder 14 is fixedly connected to the lower end of the horizontal part of the first L-shaped frame 4. A guide opening 15 is provided in the horizontal part of the first L-shaped frame 4. The inner diameter of the guide opening 15, the inner diameter of the guide cylinder 14, and the inner diameters of the two second placement openings 13 are all the same. The second placement opening 13, the guide opening 15, and the guide cylinder 14 on the right side are on the same axis. The center of the motor housing after placement corresponds to this axis. Furthermore, the specific shape of the first placement opening 12 can be set according to the shape of the motor housing, fitting the shape of the motor housing and slidingly connected. When the motor housing rotates to directly below the guide cylinder 14, it fits the lower end face of the guide cylinder 14.

[0022] The upper end of the pressure plate 7 is fixedly connected to a guide rod 8, the upper end of which passes through the horizontal part of the second L-shaped frame 5 and is slidably connected.

[0023] In this invention, during actual use, the motor housing and stator core are placed in the first placement port 12 and the second placement port 13 on the left side, respectively. Then, the drive motor 3 is started and rotated 180°. At this time, the first placement port 12 for placing the motor housing rotates to directly below the guide cylinder 14, just touching the lower end face of the guide cylinder 14. The second placement port 13 for placing the stator core rotates to the guide port 15 and slides down along the guide port 15 and the guide cylinder 14 to contact the motor housing. At this time, the hydraulic telescopic rod 6 is started, allowing the pressure plate 7 to move down and press the stator core into the motor housing, completing the assembly. Then, the hydraulic telescopic rod 6 is started to retract, and the drive motor 3 is started to rotate 180° again. Then, the assembled motor housing and stator core assembly can be removed. Compared with the prior art, the removal and placement operations are not directly below the hydraulic telescopic rod 6, which is safer and can ensure the coincidence of the core axis with the center of the housing, thereby improving the assembly quality.
