Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, specifically to a motor rotor positioning device. Background Technology

[0002] In the motor manufacturing and repair industry, precise positioning of the motor rotor is a crucial step. As the core component of the motor, the positioning accuracy of the motor rotor directly affects the motor's performance and stability. Traditional motor rotor positioning methods often rely on manual operation, which is not only inefficient but also makes it difficult to guarantee positioning accuracy and consistency.

[0003] In recent years, some highly automated motor rotor positioning devices have emerged. However, these devices still have certain limitations in design and function. For example, some devices use complex mechanical structures to achieve rotor clamping and positioning, resulting in high manufacturing costs and difficult maintenance. Other devices, although capable of automatic clamping, are prone to damaging the rotor surface during the clamping process, affecting the rotor's performance.

[0004] In view of this, we have studied and improved the existing structure and its shortcomings, and provided a motor rotor positioning device in order to achieve a more practical purpose. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] The present invention will now be described in further detail in conjunction with the full text.

[0026] Combined with appendix Figure 1 and Figure 2 A motor rotor positioning device includes a worktable 1, on which a clamp 2 is installed to clamp the motor rotor. In specific implementation of this utility model, the telescopic rod 402 can be an electric telescopic rod or a pneumatic telescopic rod, both of which can be connected to an external power source and are existing technologies that can be purchased and used directly. The spring 304 can be replaced after long-term use to ensure clamping force.

[0027] In specific implementation of this utility model, such as Figure 2 As shown. The fixture 2 includes a limiting block 201 mounted opposite to the worktable 1. A sliding block 202 is mounted on one side of the limiting block 201, and a clamping plate 203 is mounted on the upper end of the sliding block 202. A sliding groove 5 is formed on one side of the limiting block 201, and a slider 6 that cooperates with the sliding groove 5 is mounted on the sliding block 202. The sliding block 202 can slide within the sliding groove 5 of the limiting block 201 via the slider 6, thereby driving the two clamping plates 203 to move relative to each other.

[0028] In specific implementation of this utility model, such as Figure 2As shown. A buffer clamping device 3 is installed between the clamp 2 and the motor rotor. The buffer clamping device 3 includes a buffer pressure plate 301 that clamps the outside of the motor rotor. Guide rods 302 are installed opposite to each other on the outside of the buffer pressure plate 301 and pass through the clamping plate 203. A connecting plate 303 is installed at the end of the two guide rods 302 away from the buffer pressure plate 301. A spring 304 is installed on the outside of the guide rods 302 and between the buffer pressure plate 301 and the clamping plate 203. A through hole 7 is opened on the clamping plate 203 to cooperate with the movement of the guide rods 302. When the two clamping plates 203 move relative to each other, they drive the two buffer pressure plates 301 to clamp the outside of the motor rotor, and the guide rods 302 move in the through hole 7. The spring 304 adjusts automatically. Through the elastic force of the spring 304, the two buffer pressure plates 301 clamp the outside of the motor rotor.

[0029] In specific implementation of this utility model, such as Figure 2 As shown. A drive device 4 for relative movement of the drive fixture 2 is installed on the worktable 1. The drive device 4 includes a mirror-image movable rod 401. One end of the movable rod 401 is hinged to the moving block 202 and the other end is hinged to the worktable 1. A telescopic rod 402 is installed in the middle of the two movable rods 401. The output end and tail of the telescopic rod 402 are respectively hinged to the two movable rods 401. Both ends of the telescopic rod 402 are hinged. When the telescopic rod 402 works, it drives the two movable rods 401 to continue to rotate and fine-tune around the hinge point of the worktable 1. The other end of the movable rod 401 is hinged to the slider 6 of the moving block 202, thereby driving the moving block 202 to slide on one side of the limiting block 201.

[0030] In a specific implementation of this invention, the hinge can be achieved using a shaft and shaft hole. A sector-shaped limiting plate 8 is installed on the outer side of the end of each of the two movable rods 401 furthest from the moving block 202, and the two sector-shaped limiting plates 8 are engaged. When the two movable rods 401 are rotated for fine adjustment, the mutual engagement of the two sector-shaped limiting plates 8 ensures that the rotation angles of the two movable rods 401 are consistent, thereby causing the two moving blocks 202 to move relative to each other on the limiting blocks 201. A rubber layer is installed on the inner surface of the buffer plate 301.

[0031] The working principle of this utility model:

[0032] The telescopic rod 402 retracts, causing the two movable rods 401 to continue rotating and fine-tuning around the hinge point of the worktable 1. Through the mutual meshing relationship of the two fan-shaped limiting plates 8, the rotation angle of the two movable rods 401 is consistent. The other end of the movable rod 401 is hinged to the slider 6 of the moving block 202, thereby causing the moving block 202 to slide and connect on one side of the limiting block 201, causing the two clamping plates 203 to move closer to each other, causing the two buffer pressure plates 301 to clamp the outside of the motor rotor, and the guide rod 302 moves in the through hole 7. The spring 304 automatically adjusts, and through the elastic force of the spring 304, the two buffer pressure plates 301 clamp the outside of the motor rotor tightly, while reducing damage to the rotor surface. After clamping, when the rotor is removed or replaced, the telescopic rod 402 extends, causing the two movable rods 401 to move away from each other, and the two clamping plates 203 to move away from each other, finally causing the two sets of buffer pressure plates 301 to move away from each other, releasing the clamping of the rotor, removing the rotor, and completing the working cycle of the entire positioning device.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
