[0025] 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.

[0026] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 This utility model provides an embodiment of a drilling guide device for an arc milling machine tool, comprising a housing 1. The housing 1 is the main frame of the entire device, providing a fixed and supporting foundation for all internal and external mechanisms (tool protection mechanism, splash protection mechanism). It not only serves to install other components but also protects the internal components of the device from external environmental influences. The housing 1 has a guide groove 2 inside, which, through its straight setting, guides the angle of the tool, preventing damage due to angle issues. The housing 1 also houses a tool protection mechanism, whose main function is to protect the tool from external interference when not in operation, while ensuring operational safety. It avoids damage to the cutting tool and machine tool due to collision or accidental contact. The outer side of the housing 1 is fixedly connected with a splash protection mechanism. The purpose of the splash protection mechanism is to prevent splashes generated during the drilling process from causing harm to the operator or the surrounding environment, while protecting the machine tool and working environment from liquid contamination. The housing 1 has a device mounting slot 13 inside. The machine tool completes the installation of the device by clamping the device mounting slot 13. The outer side of the device mounting slot 13 is provided with an insulating ring to prevent the tool holder and the clamping device from being directly connected with different polarity voltages, which would cause a short circuit.

[0027] The tool protection mechanism includes a guide sleeve 7, which is an annular sleeve that slides inside the housing 1. Its function is to limit the tool's range of motion and prevent it from deviating from its working trajectory. The guide sleeve 7 is made of wear-resistant material and has a smooth surface or is coated with lubricant to reduce friction with the guide groove 2. The guide sleeve 7 is slidably connected inside the housing 1, and a contact support shaft 12 is threaded to the bottom of the guide sleeve 7. The contact support shaft 12 provides support and positioning at the bottom of the guide sleeve 7. It has a flat-bottomed conical shape, providing a certain degree of elasticity and stability. The side with the smaller opening contacts the area to be drilled, helping to position the working area and withstand the reaction force of the tool, ensuring accurate entry of the tool into the workpiece. A reset mechanism is fixedly connected to the top of the guide sleeve 7. The reset mechanism ensures that the guide sleeve 7 automatically returns to its initial position after work is completed, preventing interference between the sleeve and the working area. A return spring 6 pushes the guide sleeve 7 back through elastic force. The reset mechanism includes the return spring 6, which is a key component ensuring that the guide sleeve 7 can automatically return to its initial position. It uses elasticity to ensure that the protective sleeve will not stay in a deviated position due to inertia or other external forces. The return spring 6 is fixedly connected to the inside of the housing 1. The inside of the housing 1 has a cavity. The return spring 6 is fixedly connected to the inside of the cavity. The guide protective sleeve 7 is fixedly connected to the bottom of the return spring 6. The outside of the guide protective sleeve 7 has a sliding groove. Specifically, the guide protective sleeve 7 is an I-shaped round shaft, and the contact support shaft 12 is a flat-bottomed conical round shaft. The side with the smaller opening of the contact support shaft 12 contacts the area to be drilled.

[0028] Reference Figures 1 to 3The splash protection mechanism includes two protective shells 4. The function of the protective shells 4 is to block splashes and maintain a clean working environment. They are made of corrosion-resistant and high-temperature-resistant materials and can withstand a certain amount of mechanical impact. Each protective shell 4 has an opening to allow components in the working area to pass through. A mounting shaft 3 is fixedly connected to the adjacent side of the two protective shells 4, allowing the protective shells 4 to be detachably connected to the machine tool via the mounting shaft 3. The mounting shaft 3 allows the protective shells 4 to rotate around its axis or remain in a fixed position, facilitating installation and disassembly. A splicing assembly is fixedly connected to the bottom of each protective shell 4, splicing the two protective shells 4 together and assisting the mounting shaft 3 in installing the splash protection mechanism. The splicing assembly allows the splash protection mechanism to be disassembled and maintained, improving the device's practicality. Two sealing strips 5 are fixedly connected to the adjacent side of the two protective shells 4. The sealing strips 5 enhance the sealing between the protective shells 4, preventing liquids or splashes from splashing from the contact surface. It plays an important protective role at the connection part of the protective shell 4. The two sealing strips 5 are respectively connected to the two protective shells 4. The splicing assembly includes four mounting screws 10, which are used to connect the two splicing limiting blocks 8 to the bottom of the protective shell 4. At the same time, because it is a threaded connection, the splicing limiting blocks 8 can be disassembled for easy maintenance. The four mounting screws 10 are fixedly connected to the bottom of the protective shell 4. The four mounting screws 10 are in pairs. The splicing limiting blocks 8 are fixedly connected to the outside of the two mounting screws 10. The two splicing limiting blocks 8 stand opposite each other. Because there is an adjustment groove inside, the splicing limiting blocks 8 can limit the movement angle and range of the splicing block 9. The splicing limiting blocks 8 are slidably connected to the inside of the splicing adjusting block 11. As a connector between two splicing blocks 9, the position of the splicing block 9 is adjusted by adjusting the position of the installation adjustment block 11, thereby completing the splicing of the splicing assembly. The splicing block 9 is fixedly connected to the side of the installation adjustment block 11. The splicing block 9 is used to complete the splicing of the protective shell 4 and ensure the integrity of the splash protection area. The splicing block 9 is semi-circular, and the splicing limit block 8 is semi-circular. The two splicing limit blocks 8 stand opposite each other to form a circle. The installation adjustment block 11 stands opposite each other. A splash protection mounting groove is opened on the outside of the shell 1. The splash protection mounting groove provides an installation position for fixing the splash protection mechanism so that it is stably fixed on the outside of the shell 1. The mounting shaft 3 fits into the splash protection mounting groove.

[0029] Working Principle: The working process of this drilling guide device mainly involves three key parts: tool protection, guidance and positioning, and splash protection. During operation, firstly, the housing 1 serves as the frame of the entire device, providing a fixed and supportive foundation for all components, ensuring the stability of the device. The guide groove 2 inside the housing 1 guides the tool along a specific trajectory, thereby avoiding tool damage due to angle issues. When starting operation, the tool protection mechanism protects the tool through the guide sleeve 7, preventing external interference when not in operation. The guide sleeve 7 slides within the housing 1, limiting the tool's range of motion and ensuring that the tool can accurately enter the area to be drilled.

[0030] When the cutting tool begins operation, the return spring 6 ensures that the guide sleeve 7 automatically returns to its original position after operation, preventing interference with the working area and ensuring operational safety. Simultaneously, the contact support shaft 12 provides support at the bottom of the guide sleeve 7, aiding in workpiece positioning.

[0031] Regarding splash protection, the external splash protection mechanism consists of two protective shells 4. These shells effectively block splashes generated during drilling, ensuring a clean operating environment. The protective shells 4 are detachably connected to the machine tool via mounting shafts 3 and fixed by splicing components, allowing them to rotate around the axis or remain in a fixed position. Sealing strips 5 enhance the seal between the protective shells 4, preventing leakage of liquids or splashes. The splicing components at the bottom of the protective shells 4 facilitate disassembly and maintenance of the splash protection mechanism. These components consist of splicing limit blocks 8, splicing blocks 9, mounting screws 10, and mounting adjustment blocks 11. The mounting screws 10 fix the splicing components to the bottom of the protective shells 4. By adjusting the position of the mounting adjustment blocks 11 and the position of the splicing blocks 9, the splicing components are finally assembled. The splicing limit blocks 8 restrict the adjustment orientation and movement range of the mounting adjustment blocks 11 and splicing blocks 9.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
