[0002] In modern industry, drill bits are key components of drilling equipment, and their performance directly affects the efficiency and quality of drilling operations. However, during the drilling process, the high-speed friction and impact between the drill bit and the material generate a large amount of heat, causing the drill bit temperature to rise. High temperatures not only reduce the hardness and wear resistance of the drill bit but also accelerate wear and even cause deformation or damage, thus seriously affecting the normal progress of drilling operations. Therefore, effective cooling of drill bits is an important means to ensure smooth drilling operations, extend drill bit lifespan, and reduce operating costs. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0029] The following will refer to the appendix. Figures 1 to 6 The present invention will be described in detail with reference to the embodiments.

[0030] Overall, this utility model relates to a drill bit cooling device, including a workbench 1, a lifting device 2 fixedly mounted on the workbench 1, and an electric drill body 3 fixedly mounted on the lifting device 2; vertical plates 5 symmetrically fixedly mounted on the top surface of the workbench 1; a receiving cavity 6 disposed between the vertical plates 5 via a sliding plate 502; a funnel-shaped lower shield 602 slidably mounted in the receiving cavity 6; a water pipe 603 fixedly surrounding the inner side wall of the receiving cavity 6; and nozzles 604 spaced apart on the water pipe 603. The water pipe 603 is connected to a water storage container 606 via a connecting pipe 605 extending to the outside of the receiving cavity 6; the drill bit of the electric drill body 3 enters downward into the receiving cavity 6 and exits through the lower shield 602 to drill holes.

[0031] In this invention, the combination of the water pipe 603 and the nozzle 604 allows for the direct and uniform spraying of coolant onto the working area of ​​the drill bit, effectively reducing its temperature, extending its service life, and improving drilling efficiency and accuracy. Furthermore, the funnel-shaped lower shield 602 design not only ensures that the coolant directly acts on the drill bit but also effectively prevents coolant splashing, reducing water waste. The lower shield 602 can also slide up and down within the receiving cavity 6 to adjust its position, adapting to different cooling requirements. In addition, the enclosed receiving cavity 6 design reduces the risk of injury to operators from splashed debris during operation, improving operational safety.

[0032] In detail, the function of the lower shield 602 sliding up and down within the receiving cavity 6 allows it to adjust its position according to different working conditions and the actual cooling needs of the drill bit, optimizing the distribution of coolant and ensuring that the coolant can act more effectively on the working area of ​​the drill bit, further improving the cooling effect and operating efficiency.

[0033] In practice, firstly, the water storage container 606 is filled with an appropriate amount of coolant, ensuring that the connection between the water pipe 603 and the water storage container 606 via the connecting pipe 605 is unobstructed. Then, according to the drilling requirements, the electric drill body 3 and the drill bit are adjusted to a suitable height using the lifting device 2. The water pump inside the water storage container 606 is turned on, and coolant is drawn from the water storage container 606, flowing through the water pipe 603 into each nozzle 604. At this time, the nozzles 604 begin to evenly spray coolant into the receiving cavity 6. The electric drill body 3 is started, and the drill bit, driven by the motor, begins to rotate and descend into the receiving cavity 6. As the drill bit descends, it passes through the funnel-shaped lower shield 602 and contacts the surface of the material to be drilled, beginning the drilling process. During drilling, the nozzles 604 continuously spray coolant, directly acting on the drill bit and the drilling area, effectively reducing the temperature and helping to remove drilling debris. The design of the lower shield 602 ensures that the coolant does not splash everywhere but is concentrated in the drilling area. Once the predetermined drilling depth is reached, shut off the main body 3 of the electric drill and raise the drill bit to a safe position using the lifting device 2. At this point, the water pump can be turned off to disconnect the water supply.

[0034] It should be noted that after the device has completely stopped operating, the debris and residual moisture in the receiving cavity 6 should be cleaned, and all components should be checked for damage in order to prepare for the next use.

[0035] like Figure 4 As shown, in order to facilitate the adjustment of the position of the receiving cavity 6 and further increase the overall flexibility, in this embodiment, the vertical plate 5 is provided with a sliding assembly for the receiving cavity 6 to slide up and down. The sliding assembly includes a sliding groove 501 on both sides of the vertical plate 5, a sliding plate 502 that cooperates with the sliding groove 501 and slides up and down in the sliding groove 501, and a limiting plate 503 is fixedly provided at the outer end of the sliding plate 502. A pin 504 is inserted into the limiting plate 503, and a plurality of insertion holes 505 that cooperate with the pin 504 are opened at intervals along the height direction on the side wall of the vertical plate 5.

[0036] In this embodiment, by introducing a sliding component, the receiving cavity 6 can slide up and down along the vertical plate 5, which not only facilitates the adjustment of its position according to the different working requirements of the drill bit, but also ensures stability during the drilling process and avoids errors or damage caused by vibration.

[0037] like Figure 3 As shown, as a preferred structure in this embodiment, a funnel-shaped upper shield 601 is fixedly provided at the top opening of the receiving cavity 6. This configuration not only guides the flow of coolant but also effectively prevents coolant from splashing out during drilling, keeping the working environment clean and reducing the potential hazards of coolant to operators and surrounding equipment.

[0038] like Figure 1As shown, it should be further explained that in this embodiment, the top of the workbench 1 is embedded with a support groove 4 below the electric drill body 3, and the support groove 4 has a water inlet hole 401 facing the electric drill body 3; the vertical plate 5 is fixedly installed on the top surface of the support groove 4, and the support groove 4 has an inner cavity, with one side being open.

[0039] It should be further explained that the support groove 4 embedded in the top of the workbench 1 is an integrated design with the workbench 1, which not only saves space but also allows coolant to flow directly into the inner cavity of the support groove 4 through the water inlet 401, providing immediate cooling for the drill bit and improving the efficiency of drilling operations. The support groove 4 has an inner cavity and one side is open, which makes it easy for operators to clean up debris and residual coolant generated during drilling, reducing maintenance difficulty and cost.

[0040] Preferably, the outer wall of the lower shield 602 is threaded, and the inner wall of the receiving cavity 6 is screwed to the top side wall of the shield. The threaded design of the outer wall of the lower shield 602 and the screwed connection between the inner wall of the receiving cavity 6 and the top side wall of the shield ensures a stable connection between the shield and the receiving cavity 6, enhances the strength and stability of the entire structure, and effectively prevents loosening or falling off due to vibration during drilling.

[0041] Furthermore, such as Figure 1 and Figure 6 As shown, in order to increase the cooling effect at the connection between the drill bit and the motor of the electric drill body 3, the bottom of the lifting device 2 is provided with a mounting shell 7, which surrounds the electric drill body 3. A fan 702 is fixed on the mounting shell 7, and multiple heat sinks 701 are fixed on the inner side wall of the mounting shell 7.

[0042] The mounting housing 7 is designed around the drill body 3 and is equipped with a fan 702 and multiple heat sinks 701, forming an effective heat dissipation system. The operation of the fan 702 can accelerate airflow and remove the heat generated by the drill body 3, while the heat sinks 701 increase the heat dissipation area and improve heat dissipation efficiency, thereby ensuring the stable performance of the drill body 3 under long-term high-intensity operation and extending its service life.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
