[0003] Chinese Patent Authorization Announcement No.: CN220638469U A drill bit for easy chip removal includes a protective sleeve, an elastic component mounted on the inner wall of the protective sleeve, and a plurality of guide components mounted symmetrically on the inner wall of the protective sleeve. A drill bit is placed on the inner wall of the protective sleeve, the elastic component is used to support the drill bit, and the guide component is used to position the drill bit. A mounting hole is formed at the top of the protective sleeve, and a slide is slidably connected to the inner wall of the protective sleeve. An elastic pressure plate is fixed to the inner end of the slide, and the inner end of the elastic pressure plate abuts the top of the drill bit. A guide rod is fixed to the inner wall of the protective sleeve, and the outer wall of the guide rod is provided with two springs. A second slide groove is formed at the top of the slide, and the inner end of the guide rod passes through the elastic pressure plate and is slidably connected to it.

[0035] Example 1:

[0036] See also Figure 1-6 , a drill bit that is easy to remove chips, includes a base 1, a micro motor 2 is installed on the upper surface of the base 1, and a waste chip trough 3 is fixedly connected to the output end of the micro motor 2, an auxiliary cleaning component 4 is installed above the waste chip trough 3, a drill rod 6 is engaged and connected in the auxiliary cleaning component 4, and a mounting component 5 is installed on the auxiliary cleaning component 4. The upper end of the auxiliary cleaning component 4 is provided with a mounting groove 7, and the mounting component 5 is installed in the mounting groove 7. In this scheme, an auxiliary cleaning component 4 and a micro motor 2 are provided, the micro motor 2 is started, and then the waste chip trough 3 fixedly connected to its output end is driven to rotate, and then the auxiliary cleaning component 4 installed with the waste chip trough 3 is driven to rotate. When the drill rod 6 is inserted into the auxiliary cleaning component 4, the rod body of the drill rod 6 is cleaned, and the cleaning range is wide and the cleaning effect is good.

[0037] See also Figure 1-6Two groups of insertion rods 8 are fixedly connected to the upper surface of the top of the waste chip trough 3, and two groups of insertion holes 14 corresponding to the insertion rods 8 are opened on the lower surface of the bottom end of the auxiliary cleaning component 4, and the two groups of insertion holes 14 are adapted to the two groups of insertion rods 8. By setting the insertion rods 8 and the insertion holes 14, the waste chip trough 3 and the auxiliary cleaning component 4 are combined and installed, which facilitates subsequent rotation cleaning.

[0038] See also Figure 1-3 The auxiliary cleaning component 4 includes a protective shell 41, which is sleeved on the insertion rod 8. An inclined groove 42 is opened inside the protective shell 41, and multiple groups of cleaning rods 43 are installed on the inclined groove 42. By inserting the protective shell 41 on the insertion rod 8, the structure is spliced. By setting the inclined groove 42 and the cleaning rod 43, corresponding parts are provided for subsequent cleaning.

[0039] See also Figure 1-2 A pair of symmetrical connecting springs 44 are installed at the lower end of the protective shell 41, and a guide inclined plate 45 is installed at one end of the two sets of connecting springs 44. By setting the guide inclined plate 45, the chips inside the device after cleaning will flow along the guide inclined plate 45. Since the guide inclined plate 45 has a certain inclination, these chips are discharged along the guide inclined plate 45 under gravity.

[0040] See also Figure 1-6 The two sets of guide inclined plates 45 are adapted to the drill body 10. By such an arrangement, the guide inclined plates 45 can clamp drill bits of different sizes, thereby improving the applicability of the device.

[0041] See also Figure 1-3 The mounting assembly 5 includes an airbag 51, which is installed in the mounting groove 7. A vent tube 52 is inserted at one end of the airbag 51, and the vent tube 52 passes through the outer wall of the auxiliary cleaning assembly 4. A manual inflatable ball 53 is installed at the outer end of the vent tube 52. By setting the mounting assembly 5, the drill rod 6 is installed more securely in the protective shell 41, and its adjustable feature enables it to adapt to drill bits of different sizes.

[0042] See also Figure 1-4 The bottom end of the drill rod 6 is fixedly connected to the drill body 10, and the outer surfaces of the drill body 10 and the drill rod 6 are both provided with a coating. The middle section of the drill rod 6 is provided with a chip groove 9. The chip groove 9 has the same thread direction as the inclined groove 42. The chip groove 9 corresponds to multiple groups of cleaning rods 43. Through this arrangement, the cleaning rods 43 can clean the chip groove 9 more fully, thereby improving the cleaning effect.

[0043] See also Figure 1-5An inner cavity is opened inside the upper end of the drill rod 6, and a coolant storage chamber 11 is installed on the inner cavity. A vertical inner cooling hole 12 is opened inside the drill rod 6 below the output end of the coolant storage chamber 11, and the vertical inner cooling hole 12 extends to the inside of the drill bit body 10. A plurality of groups of horizontal inner cooling holes 13 are opened on the drill rod 6 on both sides of the vertical inner cooling hole 12, and the plurality of groups of horizontal inner cooling holes 13 are communicated with the vertical inner cooling hole 12. By providing the vertical inner cooling holes 12 and the horizontal inner cooling holes 13, the coolant can flow into the drill rod 6 and the drill bit body 10 conveniently, thereby reducing the heat generated by the drill bit during use, thereby preventing the drill bit from being damaged by high temperature.

[0044] The working principle of the present invention is as follows: the staff first holds the protective shell 41 horizontally and inserts the drill rod 6 into the protective shell 41, first holds the manual inflation ball 53 by hand, the pressure in the manual inflation ball 53 increases, and the gas enters the air bag 51 through the ventilation tube 52, and the air bag 51 begins to expand and clamps the upper end of the drill rod 6, properly clamps the drill rod 6 to ensure that the drill rod 6 can rotate, and the drill body 10 passes between the two sets of guide inclined plates 45. According to different sizes, the connecting spring 44 is compressed and adapts to the drill body 10. After installation, the protective shell 41 is held and the insertion hole 14 is aligned with the insertion rod 8, and the protective shell 41 is inserted downward to install the protective shell 41 on the waste chip chute 3; when cleaning the chip chute 9, the micro motor 2 is started, and the output end of the micro motor 2 rotates to drive the waste chip chute 3 to rotate. After the waste chip chute 3 is installed with the protective shell 41, the protective shell 41 is driven to rotate. The protective shell 41 rotates and is connected to the protective shell 41, continuously cleaning the chip chute 9 along the inclined slot 42, and the chips are removed. The liquid flows into the waste chip trough 3 along the guide inclined plate 45. After cleaning, the micro motor 2 is turned off and the waste chip trough 3 is unplugged for subsequent processing of the chips. When the drill rod 6 and the drill body 10 are used, the temperature of the drill rod 6 and the drill body 10 increases during use. The coolant in the coolant storage chamber 11 flows into the vertical inner cooling hole 12 by gravity. As the coolant is continuously injected into the vertical inner cooling hole 12, the vertical inner cooling hole 12 begins to be filled. After the coolant in the vertical inner cooling hole 12 is filled, Since the internal space of the vertical inner cooling hole 12 is limited and the vertical inner cooling hole 12 is connected to the horizontal inner cooling hole 13, the coolant flowing into the vertical inner cooling hole 12 begins to overflow into the horizontal inner cooling hole 13, and then gradually fills the horizontal inner cooling hole 13. Since the vertical inner cooling hole 12 and the horizontal inner cooling hole 13 are arranged inside the absorbing drill rod 6 and the drill bit body 10, as the coolant flows into the vertical inner cooling hole 12 and the horizontal inner cooling hole 13, the coolant absorbs the heat inside the drill rod 6 and the drill bit body 10 and thus reduces their temperature.

[0045] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
