Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-4 As shown, a rotor core slot depth detection mechanism includes a displacement sensor fixing support 17 and an open-type guide shaft support 16 disposed on the upper side of the displacement sensor fixing support 17; a displacement sensor body 8 is disposed at the middle position of the open-type guide shaft support 16; a rotor core 11 is disposed at the bottom position of the displacement sensor body 8; a rotor core limiting fixture 12 is disposed at the bottom outer side of the rotor core 11, a metal sensor body 3 is disposed in the wall of the rotor core limiting fixture 12, and a metal sensor fixing plate 4 is connected to the bottom position of the metal sensor body 3. A retractable column 10 is provided at the rear position, and a buffer 9 is provided at the upper position of the retractable column 10. When the displacement sensor fixing support 17 is raised and lowered, it drives the displacement sensor body 8 to rise and fall. At the same time, the retractable column 10 will first contact the rotor core 11 and be buffered by the buffer 9. After the improvement of this utility model, a rotor core limiting fixture 12 is added to the overall structure to prevent the operator from placing the rotor core 11 in reverse. A buffer 9 is also added to reduce the collision force between the component and the rotor core 11 and protect the rotor core 11 from damage. This effectively improves the practicality of the rotor core 11 waist groove depth detection mechanism.

[0028] like Figure 3 and Figure 4As shown, a second built-in telescopic body 24 is provided at the bottom center of the rotor core limiting fixture 12. A vent pipe 21 is connected to the bottom of the second built-in telescopic body 24. A first built-in telescopic body 22 is provided at the end of the vent pipe 21.

The connecting inner post 19 is glued to the first built-in telescopic body 22. The upper side of the connecting inner column 19 is provided with an upper connecting pressing plate 20. Pressing the connecting inner column 19 can compress the internal air of the built-in telescopic body 1, which will enter the built-in telescopic body 24, causing the built-in telescopic body 24 to extend and expand, thereby lifting the rotor core 11 and enabling it to move in the vertical direction. This effectively reduces the occurrence of scratches on the side of the rotor core 11 due to tilting when the operator removes it, and thus effectively improves the practicality of the rotor core 11 waist groove depth detection mechanism.

During operation, the drive cylinder 2 can drive the component mounting plate 15 to move the displacement sensor fixing support 17 and the displacement sensor body 8 on it to adjust the height. According to the actual measurement requirements, the parameters of the displacement sensor body 8 are set, including laser emission power, receiver gain, sampling frequency, etc., and calibrated by standard gauge blocks or other reference objects of known size to verify the measurement accuracy and repeatability of the displacement sensor body 8. Real-time measurement is started, and real-time depth data is acquired through the data acquisition system. The data is further processed and analyzed, such as calculating statistical data such as average value, maximum value, and minimum value, to evaluate the quality and consistency of the depth.

[0031] like Figure 1As shown, a T-shaped guide shaft support 7 is provided at the bottom of the guide shaft 6. The guide shaft 6 is connected to the T-shaped guide shaft support 7 by plugging and fastening with screws. The T-shaped guide shaft support 7 is connected to the base plate 1 provided at its lower side by screws. The guide shaft 6 can be installed and connected to the base plate 1 through the T-shaped guide shaft support 7. The bottom area of ​​the T-shaped guide shaft support 7 is large, which can improve the stability of the guide shaft 6 during installation.

[0032] During operation, the rotor is placed on the rotor core limiting fixture 12. At this time, the metal sensor body 3 is triggered, activating the upper and lower cylinders to drive the retractable column 10 and the buffer 9 aligned with the waist-shaped hole of the core. At the same time, the displacement sensor monitors the displacement of the retractable column 10. If the displacement meets the set value, the product is qualified; otherwise, it is unqualified.
