The right side of the reinforcing plate 14 is fixedly connected to the left side of the sliding block 15. The reinforcing plate 14 can reinforce the first hydraulic telescopic rod 11 and the sliding block 15, thereby enhancing the stability of the device.

[0026] The inner wall of the movable block 18 is fixedly connected to a first bearing 17, the inner ring of the first bearing 17 is fixedly connected to a drive motor 16, the output end of the drive motor 16 is fixedly connected to a rotating column 22, the bottom end of the rotating column 22 is fixedly connected to a fixing plate 19, and the inner wall of the reinforcing plate 14 is threadedly connected to four fixing bolts 13. The outer surface of each set of fixing bolts 13 is threadedly connected to the inner wall of the sliding block 15. The fixing bolts 13 can fix the reinforcing plate 14 and the sliding block 15 to prevent them from shifting their position during use.

[0027] The inner wall of the fixed plate 19 is threaded with two threaded rods 24. The outer surface of each threaded rod 24 is fixedly connected with a second bearing 26. The bottom ends of the two second bearings 26 are fixedly connected with a grinding disc 23. The outer surface of each threaded rod 24 is threadedly connected with a limit nut 25. The outer surface of the second hydraulic telescopic rod 20 is fixedly connected with a dustproof shell 21. The right side of the dustproof shell 21 is fixedly connected to the inner wall of the second slide groove 6.

[0029] The working principle of this utility model is as follows: In use, the iron core body 8 is first placed in the groove 10 on the placement plate 9. When grinding is required, the telescopic end of the first hydraulic telescopic rod 11 is retracted, causing the sliding block 15 to slide in the first sliding groove 5, thereby moving the position of the iron core body 8 to achieve adaptive positioning and enhance the practicality of the device. Then, by twisting the threaded rod 24 and the limiting nut 25, the height of the grinding disc 23 can be adjusted to achieve high-precision grinding. Next, the telescopic end of the second hydraulic telescopic rod 20 is extended, causing the movable block 18 to move, thereby moving the grinding disc 23. The output end of the drive motor 16 is rotated, causing the rotating column 22 to rotate, which in turn causes the fixed plate 19 and the grinding disc 23 to rotate. This allows the iron core body 8 to be ground, effectively avoiding the problem of not being able to grind the end faces of iron cores of different thicknesses, which easily leads to material waste.
