[0029] Specifically, the iron core is placed in the placement groove 11, and the iron core can be clamped by the clamping assembly 20 provided on the workbench 10, and the clamping plate 29 is moved downward by the cam rotating mechanism, thereby realizing the upper side limitation of the iron core.

[0030] like Figure 1 As shown, threaded rods 23 are fixedly provided on the bottom wall surfaces of the two brackets 25, and limiting grooves 22 that are movably engaged with the corresponding threaded rods 23 are opened on the wall surface of the workbench 10, wherein a threaded rod 23 is rotatably connected in one of the limiting grooves 22, and the threaded rod 23 is threadedly connected to the limiting sleeve 21 in the limiting groove 22, and one side wall surface of the threaded rod 23 movably passes through the inner wall of the workbench 10, and a turntable 24 is fixedly provided at the end of the threaded rod 23, and the turntable 24 is located on one side wall surface of the workbench 10.

[0031] Specifically, this solution can realize the rotation of the threaded rod 23 by rotating the turntable 24, so that the two brackets 25 can drive the clamping plate 29 to move, so as to realize the limited clamping of different parts of the iron core.

[0032] like Figure 1 and Figure 2 As shown, a positioning plate 30 is fixedly provided on the side wall of the bracket 25 away from the threaded rod 23. The positioning plate 30 is in a fit with the wall of the workbench 10. A vertical positioning bolt 32 is movably passed through the positioning plate 30. A plurality of positioning threaded holes 31 are provided on the wall of the workbench 10 on this side. The positioning bolts 32 pass through the positioning plate 30 and are threadedly connected with the positioning threaded holes 31.

[0033] Specifically, the present solution can realize auxiliary positioning of the bracket 25 through the positioning plate 30 and the positioning bolt 32. After the position of the bracket 25 is adjusted, in order to prevent the iron core from being clamped unstable during the cutting process, the positioning plate 30 can be fixed by threading the positioning bolt 32 with the positioning threaded hole 31. In this way, both brackets 25 can be more stable, and the stability of the clamping plate 29 can also be improved, thereby improving the stability of the clamping assembly of the present solution.

In this way, the rotation degree of the cam 28 can be adjusted according to the diameter of the iron core, and the clamping limit of the iron core can be achieved. In addition, this solution can also meet the limit clamping of iron cores of different diameters.

A cutting groove 12 that passes through from top to bottom is opened in the middle of the wall of the workbench 10, and the positions of the cutting groove 12 and the cutter 17 correspond to each other up and down, a collecting box 13 is movably mounted on the bottom wall of the workbench 10, and T-shaped sliders 14 are fixedly arranged on both side walls of the top of the collecting box 13, and sliding grooves that movably engage with the T-shaped sliders 14 are opened on both side walls of the bottom of the workbench 10.

[0039] Specifically, after the iron core is placed in the placement groove 11, the two ends of the iron core are clamped by the clamping assemblies 20 on both sides, and the cutting part of the iron core is located in the cutting groove 12. The working switch of the hydraulic rod 16 is turned on, and the hydraulic rod 16 drives the cutter 17 to move downward. The cutter 17 cuts the iron core in the cutting groove 12, and the debris generated during cutting falls into the collection box 13 through the cutting groove 12. The collection box 13 can collect the debris. After each work is completed, it can be pulled to the collection box 13 to clean up the debris in the collection box 13.
