[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0012] like Figure 1-5 As shown, this utility model provides a technical solution: A simple tool for an EDM machine includes a magnetic base 1, with a base plate 2 fixedly connected to its top. A vertical column 3 is rotatably connected to one end of the base plate 2 via a bearing. A tool head 4 is provided on the front of the column 3. An adjustment mechanism is provided between the tool head 4 and the column 3. The adjustment mechanism includes a height adjustment component and an angle adjustment component. The height adjustment component includes a lead screw 6 threaded to the upper end of the column 3 and a guide frame 7 fixedly connected to the top of the column 3 and located away from the side of the perforated mounting base 5. A knob 8 is fixedly connected to the top of the lead screw 6, and the bottom outer circumference of the knob 8 rotates via a bearing. A lifting frame 9 is connected, and a guide rod 10 is fixedly connected to the bottom end of the lifting frame 9 near the guide frame 7. A guide hole with sliding fit with the guide rod 10 is opened in the middle of the guide frame 7. The angle adjustment assembly includes a circular shell 11 fixedly connected to the outside of the side of the lifting frame 9 away from the guide rod 10. An internal meshing ratchet 12 is rotatably connected inside the end of the circular shell 11 away from the lifting frame 9. A rotating disk 13 is fixedly connected to the end of the internal meshing ratchet 12 away from the lifting frame 9. Flanges 14 are fixedly connected to the opposite ends of the rotating disk 13 and the tool head 4. The two flanges 14 are fixedly connected by bolts. The angle adjustment assembly also includes a guide seat 15 vertically fixedly connected to the inner bottom wall of the circular housing 11 on the side away from the inner meshing ratchet 12. A spring 16 is fixedly connected to the lower interior of the guide seat 15, and a lifting block 17 is fixedly connected to the other end of the spring 16. A transverse ratchet 18 is fixedly connected to the side of the lifting block 17 near the inner meshing ratchet 12. An unlocking slider 19 is slidably sleeved on the top of the circular housing 11. The bottom end of the unlocking slider 19 extends into the interior of the circular housing 11 and is fixedly connected to the top of the lifting block 17. Guide strips 20 are fixedly connected to the outer walls on both sides of the lifting block 17. Guide grooves 21 that slide with guide strips 20 are provided on both inner walls of 5. The inner circumference of the internal meshing ratchet 12 is evenly distributed with ratchet grooves. The ratchet 18 meshes with the inner circumference of the internal meshing ratchet 12. The mounting base 5 with holes is fixedly connected to the outside of the bottom end of the magnetic base 1 near the column 3. A positioning mechanism is provided between the column 3 and the base plate 2. The positioning mechanism includes a positioning block 22 fixedly connected to the bottom end of one side of the column 3, and a locking screw 23 threadedly connected to the positioning block 22. Threaded holes 24 that match the locking screw 23 are provided on the left side of the base plate 2 and at both ends of the column 3. In this embodiment, by using the lead screw 6 and guide rod 10 in the height adjustment assembly and the ratchet mechanism in the angle adjustment assembly, the height and angle of a single tool can be quickly adjusted, solving the problem of the single function of existing simple tools and significantly improving the ease of operation.

[0013] Furthermore, the dual fixing design of the magnetic base 1 and the perforated mounting base 5 not only retains the quick installation characteristics of the simple tool, but also expands its applicable range, solving the problem of the limited installation method of the existing simple tool, and enabling the tool to be used stably under various working conditions.

[0014] Working principle: In use, the entire tool is first attracted and fixed to the metal workbench by the magnetic base 1. When the mounting surface is a non-magnetic material or cannot be reliably attracted, the mounting base 5 with holes is connected and fixed to the fixing holes on the mounting surface by bolts. After fixing, loosen the locking screw 23, rotate the column 3 to the required working position, and then screw the locking screw 23 into the corresponding threaded hole 24 on the base plate 2 to lock it. Then, adjust the tool head 4 according to the processing requirements. When the height needs to be adjusted, rotate the knob 8 to drive the lead screw 6 to rotate, and drive the guide rod 10 to slide in the guide hole of the guide frame 7 through the lifting frame 9 to achieve smooth lifting and lowering of the tool head 4. When the angle of the tool head 4 needs to be adjusted in the forward direction, the rotating disk 13 is directly rotated to drive the tool head 4 to rotate. The ratchet 18 engages with the internal meshing ratchet 12 to achieve free rotation in one direction. When the angle of the tool head 4 needs to be adjusted in the reverse direction, the unlocking slider 19 needs to be pressed down to disengage the ratchet 18 from the internal meshing ratchet 12. At this time, the rotating disk 13 can be rotated in the reverse direction to drive the tool head 4 to rotate to the target angle. Then the unlocking slider 19 is released, and the ratchet 18 re-engages and locks under the action of the spring 16. Through the above adjustment mechanism, the height, angle and horizontal position of the tool head 4 can be adjusted quickly and accurately in multiple directions to meet the EDM requirements under different working conditions.

[0015] It should be specifically noted that in the specific implementation of this technical solution, the magnetic base 1 can be configured with conventional electromagnetic chucks or permanent magnet chucks (such as electrically controlled permanent magnet chucks, manual permanent magnet chucks, or electromagnetic chucks). Although these types of magnetic adsorption devices are not described in detail in the technical solution, they are magnetic fixing devices that can be conventionally selected by those skilled in the art based on actual adsorption force requirements. Their working principle and installation method follow well-known technologies in this field and do not affect the implementation of the core innovation of this solution. In practical applications, the magnetic base 1 is mainly used to provide basic fixing support, but its specific type and connection method can be adjusted according to production requirements, all of which fall within the reasonable extension scope of this technical solution.

[0016] It should be further explained that in the specific implementation of this technical solution, the tool head 4 adopts a standard electrical discharge tool head in the prior art (e.g., a high-frequency electrical discharge tool head in the Byes-400W model). Although the specific tool head model is not limited in the solution, those skilled in the art can select a suitable standard electrical discharge tool head according to processing requirements. It should be noted that the internal structure and working principle of this type of standard electrical discharge tool head are well-known technologies in the industry, and its specific implementation details do not affect the core innovation of this solution regarding the positioning and adjustment of the tool head.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
