Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a hole-making cutting tool with a protective structure. Background Technology

[0002] In the machining process, hole-making tools play a crucial role. They are widely used in various types of workpieces to complete the hole-forming operation.

[0003] Existing hole-machining tools pose significant safety hazards during use: due to the lack of an effective chip shielding structure, the high-temperature metal chips generated during the cutting process will fly at high speed under the action of centrifugal force and cutting force. These chips may not only scratch the operator's skin and impact sensitive areas such as the eyes, but may also adhere to critical components of the equipment, causing malfunctions. At the same time, the flying chips increase the risk of slippery workshop floors, causing secondary safety accidents such as slips and falls, seriously reducing the safety of the working environment. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing hole-making tools have safety hazards when used: they lack a chip shielding structure, and the high-temperature metal chips generated during cutting may fly at high speed, scratching operators, impacting their eyes, adhering to equipment and causing malfunctions, and increasing the risk of slippery workshop floors. Therefore, we propose a hole-making tool with a protective structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a hole-making tool with a protective structure, including a tool holder, fixed plates fixedly connected to both sides of the tool holder, a drill bit installed at the bottom of the tool holder, a moving groove opened on one side of the fixed plate, a moving block slidably connected inside the moving groove, a chip baffle slidably connected to the outer surface of the tool holder, the inner wall of the chip baffle being fixedly connected to the moving block, slots opened at both ends of the chip baffle, and hollow blocks fixedly connected to both ends of the tool holder;

[0006] The hollow block is equipped with a fixing mechanism for fixing the position of the chip shield.

[0007] Preferably, the fixing mechanism includes a thrust spring installed inside the hollow block, one end of the thrust spring is fixedly connected to a locking block, and the surface of the locking block is slidably connected to the inside of the locking groove.

[0008] Preferably, the hollow block has sliding grooves on both sides of its inner cavity, and the card block has sliders fixedly connected to both sides of its inner cavity, with the surface of the sliders slidingly connected to the inside of the sliding grooves.

[0009] Preferably, the external shape of the card block matches the internal shape of the card slot.

[0010] Preferably, limit grooves are provided at both ends of the inner cavity of the moving groove, and limit blocks are fixedly connected to both ends of the moving block. The interior of the limit groove is slidably connected to the surface of the limit block.

[0011] Preferably, a return spring is fixedly connected to the top of the movable block, and the top of the return spring is fixedly connected to the top of the inner cavity of the movable groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator moves the chip shield downwards, causing the chip shield to slide downwards along the moving block inside the moving groove, thus blocking the chips generated during drill bit operation. Simultaneously, the thrust spring and the locking block work together to ensure that after the chip shield moves to the appropriate position, the locking block inserts into the locking groove, fixing the position of the chip shield. This allows the chip shield to stably block chips, preventing them from flying and injuring the operator, while also improving the safety of the working environment. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5As shown, this utility model provides a technical solution: a hole-making tool with a protective structure, including a tool holder 1, fixed plates 2 fixedly connected to both sides of the tool holder 1, a drill bit 3 installed at the bottom of the tool holder 1, a moving groove 4 opened on one side of the fixed plate 2, a moving block 5 slidably connected inside the moving groove 4, a chip baffle 6 slidably connected to the outer surface of the tool holder 1, the inner wall of the chip baffle 6 fixedly connected to the moving block 5, slots 16 opened at both ends of the chip baffle 6, and hollow blocks 8 fixedly connected to both ends of the tool holder 1, a fixing mechanism for fixing the position of the chip baffle 6 installed inside the hollow block 8, the fixing mechanism including a thrust installed inside the hollow block 8. Spring 9, one end of which is fixedly connected to a locking block 10. The surface of the locking block 10 is slidably connected to the inside of the slot 16. When the operator moves the chip shield 6 downward, the chip shield 6 causes the moving block 5 to slide downward inside the moving groove 4, thus shielding the chips generated by the drill bit 3 during use. At the same time, the cooperation between the thrust spring 9 and the locking block 10 allows the locking block 10 to insert into the slot 16 after the chip shield 6 has moved to the appropriate position, fixing the position of the chip shield 6. This ensures that the chip shield 6 can stably shield the chips, preventing chips from flying and causing injury to the operator, and improving the safety of the working environment.

[0022] Reference Figure 5 As shown in this embodiment: both sides of the inner cavity of the hollow block 8 are provided with sliding grooves 11, and both sides of the card block 10 are fixedly connected with sliders 12. The surface of the sliders 12 is slidably connected to the inside of the sliding grooves 11. Through the cooperation of the sliding grooves 11 and the sliders 12, the movement trajectory of the card block 10 can be limited, avoiding the phenomenon of the card block 10 deviating during the movement, and further improving the stability of the card block 10.

[0023] Reference Figure 3 and Figure 4 As shown in this embodiment, the external shape of the card block 10 matches the internal shape of the card slot 16. The matching design ensures that the card block 10 can be accurately inserted into the card slot 16. At the same time, the matching shape can achieve a tight fit, reducing the gap between the card block 10 and the card slot 16. This not only improves the ease of assembly but also greatly enhances the stability of the structure.

[0024] Reference Figure 2 and Figure 3As shown in this embodiment: both ends of the inner cavity of the moving groove 4 are provided with limiting grooves 13, and both ends of the moving block 5 are fixedly connected with limiting blocks 14. The inside of the limiting groove 13 is slidably connected to the surface of the limiting block 14. Through the precise cooperation between the limiting groove 13 and the limiting block 14, the moving path of the moving block 5 can be precisely controlled, ensuring that there will be no swaying phenomenon during the movement. This design not only improves the movement accuracy of the moving block 5, but also effectively avoids the instability that may occur during the movement. Furthermore, this precise control mechanism significantly improves the overall stability of the moving block 5 when it drives the chip guard 6 to move, ensuring the smooth operation of the entire system.

[0025] Reference Figure 3 As shown in this embodiment: a return spring 15 is fixedly connected to the top of the moving block 5. The top of the return spring 15 is fixedly connected to the top of the inner cavity of the moving groove 4. By setting the return spring 15, an upward thrust can be applied to the moving block 5. When the chip shield 6 is released from fixation, the return spring 15 can release the stored elastic potential energy and push the moving block 5 and the chip shield 6 to reset quickly, thereby effectively improving the reset efficiency and stability of the chip shield 6.

[0026] Working principle: By moving the chip shield 6 downwards, the operator causes the moving block 5 to slide downwards within the moving groove 4, blocking the chips generated by the drill bit 3 during operation. Simultaneously, the thrust spring 9, in conjunction with the locking block 10, allows the locking block 10 to insert into the slot 16 after the chip shield 6 has moved to the appropriate position, fixing the position of the chip shield 6. This ensures the chip shield 6 stably blocks chips, preventing them from flying and injuring the operator, and improving the safety of the working environment. The sliding groove 11 and the slider 12 work together to limit the movement trajectory of the locking block 10, preventing it from shifting during movement and further improving its stability. The coordinated design of these two components ensures... The design ensures that the locking block 10 can be accurately inserted into the slot 16, and the two fit together tightly, reducing the gap between the locking block 10 and the slot 16. This not only improves the ease of assembly but also greatly enhances the structural stability. Through the cooperation of the limiting groove 13 and the limiting block 14, the movement path of the moving block 5 can be precisely limited, effectively preventing the moving block 5 from swinging during movement. This further improves the stability of the moving block 5 when it moves the chip shield 6. The reset spring 15 can apply an upward thrust to the moving block 5. When the chip shield 6 is released, the reset spring 15 can release the stored elastic potential energy, pushing the moving block 5 and the chip shield 6 to reset quickly, thereby effectively improving the reset efficiency and stability of the chip shield 6.
