Description

Technical Field

[0001] This utility model relates to the field of motor stator and rotor lamination processing technology, and more specifically to a positioning device for processing motor stator and rotor laminations. Background Technology

[0002] Motor stator and rotor laminations are the core iron core components of a motor, stamped from high-permeability silicon steel sheets. They are primarily used for the electromagnetic energy conversion of the stator and rotor. The manufacturing process of stator and rotor laminations typically includes material preparation, mold design and manufacturing, material cutting, feeding, and stamping. Lamination stamping utilizes stamping equipment and a mold to impact the metal material, causing it to undergo plastic deformation under force to obtain the desired shape. After punching, the outer wall of the motor stator and rotor laminations needs to be ground. Before grinding, a positioning device is usually used to position the motor stator and rotor laminations to facilitate subsequent grinding operations. However, existing positioning devices often lack sufficient flexibility and adaptability when dealing with motor stator and rotor laminations of different sizes. Some positioning devices can only position laminations of specific sizes; when the lamination size changes, different positioning devices need to be replaced. Moreover, the existing positioning devices are not stable enough. During the positioning process, the motor stator and rotor laminations are prone to displacement or shaking, which can lead to deviations during grinding and affect the processing quality of the motor stator and rotor laminations. This needs to be improved. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The positioning device for processing motor stator and rotor laminations involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1:

[0023] like Figure 1-6As shown, a positioning device for processing motor stator and rotor laminations includes a mounting base 1. A column 2 is fixedly connected to the center of the top of the mounting base 1. Slide grooves 27 are formed around the outer wall of the column 2. A slider 26 is slidably connected inside the slide grooves 27. A connecting frame 28 is hinged to one side of the slider 26. Four arc-shaped clamping plates 29 are provided around the outer perimeter of the column 2. One end of the connecting frame 28 is hinged to the lower part of the inner wall of the arc-shaped clamping plates 29. Multiple guide telescopic rods 292 are fixedly installed on the outer wall of the column 2. The telescopic ends of the multiple guide telescopic rods 292 are fixedly installed around the inner walls of the four arc-shaped clamping plates 29. A motor stator and rotor lamination body 3 is located above the mounting base 1. The four arc-shaped clamping plates 29 are located around the inner perimeter of the motor stator and rotor lamination body 3. The inner perimeter of the column 2 is... The device has an installation groove 21. One side of the slide groove 27 communicates with the interior of the installation groove 21. A limit block 25 is slidably connected to the upper part of the interior of the installation groove 21. The other side of the limit block 25 is fixedly connected to the outer wall of the limit block 25. A drive motor 22 and a worm gear reducer 23 are fixedly installed in the upper part of the interior of the installation groove 21. The output end of the drive motor 22 is fixedly installed in the input end of the worm gear reducer 23 through a coupling. The output end of the worm gear reducer 23 is fixedly installed in the No. 1 screw 24 through a coupling. The bottom end of the No. 1 screw 24 is rotatably installed in the bottom of the inner wall of the installation groove 21 through a bearing. The internal thread of the limit block 25 is connected to the outer wall of the No. 1 screw 24. Multiple stator slots are opened in the inner wall of the motor stator and rotor lamination body 3. A limit strip 291 is fixedly connected to the middle of the outer wall of the arc-shaped clamp 29.

[0024] In this embodiment, mounting holes are provided around the mounting base 1, which can be firmly fixed to the workbench with bolts to ensure that the entire positioning device remains stable and does not shake during operation. After the drive motor 22 starts, it is reduced in speed and increased in torque by the worm gear reducer 23, which drives the first screw 24 to rotate. Since the limit block 25 is threadedly connected to the first screw 24 and can only slide up and down in the mounting groove 21, the rotation of the first screw 24 will cause the limit block 25 to move up and down. The limit block 25 drives the arc-shaped clamping plate through the slider 26 and the connecting bracket 28. Under the guidance of the guide telescopic rod 292, the arc-shaped clamp 29 opens and closes synchronously, allowing the outer wall of the arc-shaped clamp 29 to abut against the inner wall of the motor stator and rotor lamination body 3. At the same time, the limiting strip 291 on the outer wall of the arc-shaped clamp 29 can be inserted into the stator slot on the inner wall of the motor stator and rotor lamination body 3. Through this design, the arc-shaped clamp 29 not only firmly clamps the inner wall of the motor stator and rotor lamination body 3 from all sides, but the cooperation between the limiting strip 291 and the stator slot further prevents the lamination from rotating or shifting during the grinding process, ensuring the stability of the positioning.

[0025] Example 2:

[0026] like Figure 1-6As shown, a support plate 4 is fixedly connected to the lower part of the outer wall of the column 2. Limiting grooves 41 are opened on both sides of the support plate 4. A support plate 42 is slidably connected to the upper part of the limiting groove 41. The bottom of the motor stator and rotor lamination body 3 overlaps the top of the support plate 42. A protrusion 43 is fixedly connected to the top of the support plate 42. The outer wall of the protrusion 43 is inserted into the interior of any stator slot. A second screw 45 is provided at the lower part of the inner wall of the limiting groove 41. One end of the second screw 45 is rotatably mounted on the limiting groove through a bearing. On one side of the inner wall of the groove 41, the other end of the second screw 45 extends to the outside of the support plate 4 and is fixedly connected to a knob 44. The inside of the limiting groove 41 is slidably connected to a positioning block 46. The top of the positioning block 46 is fixedly connected to one side of the bottom of the support plate 42. The inside of the positioning block 46 is threaded to the outer wall of the second screw 45. An external thread is provided on the upper part of the outer wall of the column 2. A pressure plate 5 is threaded to the upper part of the outer wall of the column 2. The bottom of the pressure plate 5 overlaps the top of the motor stator and rotor lamination body 3.

[0027] In this embodiment, rotating the knob 44 drives the second screw 45 to rotate. Since the positioning block 46 is threadedly connected to the second screw 45 and can only slide horizontally within the limiting groove 41, rotating the second screw 45 will cause the positioning block 46 to move horizontally within the limiting groove 41. The positioning block 46 drives the support plate 42 to move horizontally, thereby adjusting the position of the support plate 42. The support plate 42 can support the motor stator and rotor lamination body 3, and make the stator slot on the inner wall of the motor stator and rotor lamination body 3 fit onto the outer wall of the protrusion 43 on the top of the support plate 42, which facilitates the support and limiting of the motor stator and rotor lamination body 3. By rotating and pressing down the pressure plate 5, its bottom is tightly attached to the top of the motor stator and rotor lamination body 3, further preventing the motor stator and rotor lamination body 3 from shaking up and down during the grinding process, ensuring the stability and accuracy of the grinding process.

[0028] In summary, as Figure 1-6As shown, this positioning device for processing motor stator and rotor laminations is used by the operator who first places the motor stator and rotor lamination body 3 on the support plate 42 of the support disk 4. By rotating the knob 44, the operator drives the second screw 45 to rotate, thereby causing the positioning block 46 to move within the limiting groove 41. The positioning block 46 also drives the support plate 42 to move. The position of the support plate 42 is adjusted so that the protrusion 43 is accurately moved into any one of the stator grooves on the inner wall of the motor stator and rotor lamination body 3, achieving initial positioning. Then, the drive motor 22 is started. The drive motor 22 drives the first screw 24 to rotate through the worm gear reducer 23. The rotation of the first screw 24 causes the limiting groove 45 to move within the limiting groove 41. The positioning block 25 moves up and down within the mounting slot 21. The limiting block 25 drives the connecting frame 28 to move via the slider 26. One end of the connecting frame 28 pushes the arc-shaped clamping plate 29 until the arc-shaped clamping plate 29 is tightly attached to the inner wall of the motor stator and rotor lamination body 3. At the same time, the guide telescopic rod 292 plays a guiding and stabilizing role, ensuring the smooth movement of the arc-shaped clamping plate 29. Finally, the pressure plate 5 is threaded onto the upper part of the outer wall of the column 2, and the bottom of the pressure plate 5 overlaps the top of the motor stator and rotor lamination body 3, further fixing the motor stator and rotor lamination body 3 and preventing it from shifting or shaking during the grinding process, providing a stable and reliable guarantee for subsequent grinding operations.
