[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please refer to Figures 1-8 This utility model provides a workpiece positioning and cutting device, including a body 1. When cutting neodymium iron boron, the workpiece is cut by generating discharge through the electrode wire (usually molybdenum wire or copper wire) under the action of a high-frequency pulse power supply. The worktable system drives the workpiece to move along a preset path, while the electrode wire reciprocates at a certain speed and is kept taut by the guide wheel system. The coolant system continuously sprays coolant into the cutting area to remove heat and chips, ensuring the stability and accuracy of the cutting process. The above cutting steps are all prior art and will not be described in detail here.

[0030] However, traditional wire EDM equipment suffers from problems such as a single fixing method, inconvenient adjustment, and low automation when processing NdFeB materials. It is difficult to adapt to NdFeB workpieces of different widths and thicknesses, resulting in frequent fixture changes that increase operational complexity and time costs. To solve this problem, a cutting table 2 is set on the machine body 1, and a fixing plate 3 is installed on the cutting table 2. A workpiece positioning mechanism is installed on one side of the fixing plate 3. After the NdFeB is positioned by the workpiece positioning mechanism, the cutting stability is improved.

[0031] The workpiece positioning mechanism includes a positioning sleeve 6 and a positioning sleeve 8. The positioning sleeve 6 is located on one side of the positioning sleeve 8. The positioning sleeve 6 and the positioning sleeve 8 have the same size. The positioning sleeve 6 and the positioning sleeve 8 are used to place the workpiece to be cut.

[0032] The positioning sleeve 6 is equipped with a width adjustment component, which can position workpieces of different widths. The width adjustment component includes positioning plates 9 located on the inner walls of both sides of the positioning sleeve 6. The length of the positioning plates 9 is the same as the length of the positioning sleeve 6. Each positioning plate 9 is connected to a connecting rod 12 on both the upper and lower sides. The lower side of the connecting rod 12 is slidably set in the limiting groove 10 opened on the upper and lower sides of the positioning sleeve 6. When the workpiece is placed inside the positioning sleeve 6, the two sets of connecting rods 12 can move the two sets of positioning plates 9 relative to each other to position the workpiece, so as to fix the workpiece of different widths and ensure the stability of the workpiece.

[0033] Furthermore, reciprocating screws 11 are symmetrically installed on both the upper and lower sides of the positioning sleeve 6. The reciprocating screws 11 are threadedly connected to the connecting rod 12. In order to move the two sets of positioning plates 9 at the same time, the rotation of the reciprocating screws 11 can be achieved.

[0034] Furthermore, a bevel gear 13 is connected to the end of each reciprocating screw 11. A double-ended gear 14 and a double-ended gear 25 are rotatably mounted on the upper and lower ends of the positioning sleeve 16. One end of the double-ended gear 14 meshes with the bevel gear 13, and the other end of the double-ended gear 14 meshes with one end of the double-ended gear 25. In order to make the two sets of double-ended gears 25 rotate simultaneously, a double-ended gear 3 17 is rotatably arranged on the rear side of the positioning sleeve 16. A bevel gear 2 16 is fixedly arranged in the middle position of each of the two sets of double-ended gears 2 15. The two ends of the double-ended gear 3 17 mesh with the two sets of bevel gears 2 16 respectively. Therefore, by simply rotating the middle shaft of the double-ended gear 3 17, the bevel gear 2 16 can rotate with the double-ended gear 2 15. Combined with the meshing of the double-ended gear 2 15 and the double-ended gear 14, the bevel gear 13 rotates, which in turn causes the reciprocating screw 11 to rotate, causing the connecting rod 12 to move automatically with the positioning plate 19.

[0035] like Figure 7 and Figure 8 As shown, a thickness adjustment assembly is installed inside the positioning sleeve 2 8. The thickness adjustment assembly includes a positioning plate 2 19 located inside the positioning sleeve 2 8. The positioning plate 2 19 is used to fix the workpiece. A screw 21 is rotatably provided on one side of the positioning plate 2 19. One end of the screw 21 passes through the positioning sleeve 2 8 and is threadedly connected to the positioning sleeve 2 8. When the workpiece is placed inside the positioning sleeve 2 8, the screw 21 is rotated, and the screw 21 moves the positioning plate 2 19 to achieve positioning of workpieces of different thicknesses.

[0036] It is worth noting that side blocks 20 are provided on both sides of the positioning plate 2 19. The side blocks 20 slide in the groove 18 opened in the positioning sleeve 2 8. The side blocks 20 are located on the side of the workpiece, which further enhances the positioning effect of the workpiece.

[0037] In order to fix the workpiece positioning mechanism, a through hole 4 is provided on the fixing plate 3, and a side plate 7 is fixedly provided on one side of the positioning sleeve 6. The side plate 7 passes through the through hole 4 and is fixed by bolts 5.

[0038] In summary, the working principle of the workpiece positioning and cutting device of this utility model embodiment is as follows: the workpiece is fixed by positioning sleeve 1 6 and positioning sleeve 2 8; the width adjustment component includes positioning plate 1 9 and reciprocating lead screw 11, and automatic width adjustment is achieved by rotating double-headed gear 3 17; the thickness adjustment component includes positioning plate 2 19 and screw 21, and the thickness is adjusted by rotating screw 21. The entire device achieves automatic adjustment through a precision gear transmission system, ensuring accurate positioning and stable cutting of workpieces of different sizes.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
