Carbide countersink drills, as an important cutting tool, are used to process various hard materials and composite materials. Their processing efficiency and precision directly affect the quality and processing cost of the workpiece.
[0003] In the prior art, when a traditional carbide countersink drill is installed, its connection end is generally a threaded column, which is connected to the drill through a thread. However, after a long period of operation, due to the high intensity of the operation, the thread end is prone to slippage, and may even cause the countersink drill to break, thereby affecting the use effect of the carbide countersink drill. In order to reduce the impact of vibration on the countersink drill, the existing countersink drill is usually added with a gasket during installation. However, after a long period of use, the countersink drill will become loose from the drill, causing the countersink drill to gradually separate from the drill, thereby affecting the use effect.
[0004] Therefore, a carbide countersink drill is needed to solve the problem that the existing countersink drill is easy to fall off the drilling rig when used for a long time, resulting in low installation firmness of the countersink drill and affecting the use effect of the countersink drill.

[0026] Embodiment 1
[0027] See also Figure 1-Figure 9 The utility model provides a technical solution: a carbide countersink drill comprises a countersink drill body 1, a stud 3 is installed at the right end of the countersink drill body 1, a reinforcement ring 2 is installed on the left outer side of the stud 3, mounting grooves 9 are provided on the upper and lower sides of the reinforcement ring 2, a rubber block 4 is inserted into the inner wall of the mounting groove 9, an extended rubber plate 10 is installed on the right side of the rubber block 4, a U-shaped groove 15 is provided on the right side of the rubber block 4, and a clamping groove 11 is provided in the middle of the rubber block 4, so that the rubber block 4 can be clamped by the plug-in plate 5 conveniently; the adjacent sides of the extended rubber plates 10 on the upper and lower sides are both attached to the outer side of the stud 3, and the rubber blocks 4 on the upper and lower sides are symmetrically arranged, so that the symmetrical arrangement improves the installation firmness between the upper and lower sides of the stud 3 and the drilling rig mounting hole, thereby preventing the countersink drill body 1 from detaching from the drilling rig.
[0028] First, the countersink drill body 1 and the drill rig are installed together through the stud 3. When the countersink drill body 1 and the drill rig are threadedly installed, the extended rubber plate 10 is pushed to be plugged into the inner wall of the drill rig mounting hole, and the rubber block 4 is driven to move to the inner wall of the drill rig mounting hole. At this time, the rubber block 4 is squeezed. When the countersink drill body 1 is completely installed between the drill rig, a U-shaped groove 15 is opened on the outer side of the rubber block 4. The deformation of the rubber block 4 is utilized to make the U-shaped groove 15 fit with the inner wall of the drill rig mounting hole, thereby improving the firmness of the installation between the stud 3 and the drill rig, thereby reducing the phenomenon of thread slippage and falling off of the countersink drill body 1.
[0029] Embodiment 2
[0030] On the basis of Example 1, in order to clamp the rubber block 4 for subsequent replacement, plug-in grooves 8 are provided on the upper and lower sides of the reinforcement ring 2, and the inner wall of the plug-in groove 8 is plugged with a plug plate 5, and the side of the upper and lower plug plates 5 separated from each other is provided with a pinching groove 14. By setting the pinching groove 14, it is convenient to unscrew the stud 3, and then it is convenient for the operator to disassemble the countersink drill body 1; the side of the upper and lower plug plates 5 that are close to each other are plugged into the inner wall of the clamping groove 11, so that the plug plate 5 is used to clamp the rubber block 4 and the reinforcement ring 2 together, thereby improving the firmness of the installation of the rubber block 4.
[0031] After the countersink drill body 1 is installed through the stud 3, the plug plate 5 is inserted along the inner wall of the plug-in groove 8. At the same time, since the adjacent sides of the upper and lower plug plates 5 are plugged into the inner wall of the card slot 11, the rubber block 4 and the reinforcement ring 2 are clamped, which is convenient for subsequent disassembly and use. At the same time, the separated sides of the upper and lower plug plates 5 are provided with pinching grooves 14, so that the stud 3 can be driven by pinching the pinching grooves 14 to facilitate the disassembly of the countersink drill body 1 for use by the operator.
[0032] Embodiment 3
[0033] On the basis of the second embodiment, in order to facilitate the installation of the plug board 5, slide plates 6 are installed on the front and rear sides of the plug board 5, connecting plates 13 are installed on the sides of the upper and lower slide plates 6 that are separated from each other, and clamping heads 7 are installed on the sides of the upper and lower connecting plates 13 that are close to each other; the clamping heads 7 on the upper and lower sides are symmetrically arranged, and the adjacent ends are plugged into the inside of the reinforcement ring 2, the slide plate 6 is slidably connected to the inner wall of the plug-in groove 8, and the adjacent sides of the upper and lower connecting plates 13 are plugged into the outside of the reinforcement ring 2, so that the clamping heads 7 are used to improve the firmness between the plug board 5 and the reinforcement ring 2 to prevent the plug board 5 from detaching from the reinforcement ring 2 during use.
[0034] When the plug board 5 is plugged into the inner wall of the plug slot 8, the slide plates 6 on the front and rear sides of the plug board 5 will be driven to slide along the inner wall of the plug slot 8. Since the sides of the front and rear slide plates 6 that are separated from each other are both installed with connecting plates 13, and the adjacent sides of the upper and lower connecting plates 13 are installed with clamping heads 7, when the slide plate 6 is plugged into the inner wall of the plug slot 8, the clamping heads 7 are driven to be plugged into the inner wall of the reinforcement ring 2, and the connecting plates 13 are fit with the outer sides of the reinforcement ring 2, thereby facilitating the clamping of the plug board 5 and the reinforcement ring 2, thereby improving the stability of the installation of the plug board 5.
[0035] Embodiment 4
[0036] On the basis of the third embodiment, in order to improve the firmness of the installation of the plug board 5 , a rubber ring 12 is sleeved on the outer side of the clamping head 7 , and the upper and lower rubber rings 12 are both installed inside the reinforcement ring 2 .
[0037] When the clamp 7 is inserted into the interior of the reinforcement ring 2, the rubber ring 12 will be squeezed and the rubber ring 12 will be in a deformed state. When the clamp 7 is completely installed between the reinforcement ring 2, the rubber ring 12 will clamp the clamp 7 and the reinforcement ring 2, thereby improving the firmness of the installation between the insert plate 5 and the reinforcement ring 2.
[0038] In actual use, the countersink drill body 1 and the drill rig are first installed together through the stud 3. When the countersink drill body 1 and the drill rig are threadedly installed, the extended rubber plate 10 is pushed to be plugged into the inner wall of the drill rig mounting hole, and the rubber block 4 is driven to move to the inner wall of the drill rig mounting hole. At this time, the rubber block 4 will be squeezed. When the countersink drill body 1 is completely installed between the drill rig, a U-shaped groove 15 is opened on the outer side of the rubber block 4, so that the deformation of the rubber block 4 is utilized to make the U-shaped groove 15 fit with the inner wall of the drill rig mounting hole, thereby improving the firmness of the installation between the stud 3 and the drill rig, thereby reducing the phenomenon of thread slippage and falling off of the countersink drill body 1.
[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
