Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0023] Example 1

[0024] This utility model provides, for example Figures 1-5 As shown, a CNC electrical discharge machining (EDM) machine includes: an EDM machine tool 1, a base plate 2 inside the EDM machine tool 1, a second electric push rod 3 at the bottom of the base plate 2, a connecting plate 4 at the lifting end of the second electric push rod 3, a vertical plate 5 on the surface of the connecting plate 4, and a first electric push rod 6 on the side of the vertical plate 5; a machining plate 7, a moving groove 8 on the side of the machining plate 7, a moving plate 9 inside the moving groove 8, a lifting plate 10 inside the moving plate 9, a base 11 on the surface of the lifting plate 10, and a clamping plate 12 on the side of the base 11;

[0025] First, the clamping plate 12 can be pushed by the first electric push rod 6, so that the workpiece can be positioned and clamped by the clamping action of the two sets of clamping plates 12, which facilitates the subsequent processing of the workpiece by the EDM machine tool 1. After the processing is completed, the second electric push rod 3 can be started to move the connecting plate 4 upward, which in turn moves the processing plate 7 upward, making it convenient to remove the workpiece after processing.

[0026] Example 2: Figures 1-3As shown, a clamping plate 12 is provided for convenient positioning and clamping of the workpiece. Two sets of second electric push rods 3 are provided, and the two sets of second electric push rods 3 are symmetrically distributed about the processing plate 7. The end face of the connecting plate 4 is fixedly connected to the side of the processing plate 7. The first electric push rod 6 is fixedly connected to the side of the vertical plate 5. The moving groove 8 has a "T" shaped plate structure. A corrugated plate 13 is provided on the side of the moving groove 8. One end of the corrugated plate 13 is fixedly connected to the side of the moving groove 8, and the other end of the corrugated plate 13 is fixedly connected to the side of the moving plate 9.

[0027] More specifically, after the workpiece is placed on the surface of the processing plate 7, the first electric push rod 6 can be activated to push the moving plate 9, thereby allowing the two sets of clamping plates 12 to move and clamp the workpiece. The corrugated plate 13 can be compressed and folded to facilitate the movement of the moving plate 9, and the corrugated plate 13 can also be used to cover the top of the moving groove 8.

[0028] To facilitate clamping of workpieces of different heights, a lifting plate 10 is provided. A groove 14 is provided on the surface of the moving plate 9. A limit opening 15 is provided on the side of the groove 14. The lifting plate 10 is inserted into the groove 14. A positioning screw 16 is provided on the side of the lifting plate 10. The positioning screw 16 passes through the limit opening 15. A positioning nut 17 is screwed onto the surface of the positioning screw 16. The moving plate 9 is fixedly connected to the lifting end of the first electric push rod 6.

[0029] When using the product, if it is necessary to clamp a tall workpiece, the positioning nut 17 can be loosened first, so that the lifting plate 10 can move up and down in the groove 14, and the height of the clamping plate 12 can be adjusted. After the clamping plate 12 is adjusted to a suitable height, the positioning nut 17 can be tightened to fix the clamping plate 12 for convenient use later.

[0030] Example 3: Figure 4 and Figure 5 As shown, a limiting plate 21 is provided to facilitate the positioning of square workpieces. The clamping plate 12 is fixedly connected to the side of the base 11 by bolts. The clamping plate 12 has an arc-shaped plate structure. A fixing screw 18 is provided on the side of the clamping plate 12. A fixing nut 19 is screwed onto the fixing screw 18. A positioning frame 20 is sleeved on the surface of the fixing screw 18. The positioning frame 20 has a limiting plate 21 on its side. The limiting plate 21 has a square plate structure. A threaded tube 22 is provided on the side of the limiting plate 21. A limiting bolt 23 is screwed into the threaded tube 22. The limiting bolt 23 passes through the limiting plate 21.

[0031] More specifically, when it is necessary to position a square workpiece, the positioning frame 20 can first be fitted onto the fixing screw 18, and then the fixing nut 19 can be tightened to fix the limiting plate 21. Subsequently, the first electric push rod 6 can be used to push the limiting plate 21, so that the square limiting plate 21 can be conveniently used to position the square workpiece. When positioning an irregular workpiece, the limiting bolt 23 can be rotated so that the limiting bolt 23 passes through the limiting plate 21. The limiting bolt 23 can achieve multi-point positioning of irregular workpieces.
