Abstract
Description
Technical Field
[0001] This utility model relates to the field of drill bit technology, and more specifically, to a drill bit for reaming holes in a drilling rig. Background Technology
[0002] Drill bits are an indispensable and important component in mechanical production. Driven by a motor, the drill bit can rotate at high speed, thus driving the entire drill bit in a centripetal motion. Through cutting, grinding, and other methods, the drill bit can create cracks in the workpiece, ultimately achieving the purpose of drilling. Among them, the reaming drill bit is a special type of drill bit, mainly used to expand existing holes to achieve the required hole diameter.
[0003] However, during actual drilling, drill bits inevitably generate a large amount of debris. If this debris is not cleaned in time, the accumulated debris will interfere with the normal operation of the drill bit, reduce drilling accuracy, increase the surface roughness of the hole wall, and may even lead to uneven hole diameter, failing to meet strict tolerance requirements. It may also damage the drill bit and the workpiece being drilled. Currently, most drill bits lack effective cleaning mechanisms, making it impossible to remove the debris generated during drilling in a timely manner. This not only increases the workload of operators, who have to frequently interrupt operations for manual cleaning, but may also lead to decreased drilling accuracy and even safety accidents.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] In view of the problems in the related technologies, this utility model proposes a drill bit for hole enlargement in drilling rigs to overcome the above-mentioned technical problems existing in the existing related technologies.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A drill bit for reaming in a drilling rig includes a drill bit body. A dust collection hood is connected to the top of the drill bit body via a first bearing. The top of the dust collection hood is provided with a connector, which is connected to a dust collection pipe. One end of the dust collection pipe is connected to a collection box. A filter screen is provided inside the collection box. One side of the collection box is connected to an exhaust fan.
[0008] Furthermore, an installation block is fixedly connected to the top of the drill bit body. An installation groove is provided on the top of the installation block, and the installation groove matches the installation block. A groove is provided inside the installation block, and a spring is provided inside the groove. One end of the spring is connected to the installation block, and the other end of the spring is connected to the locking pin. A locking slot is provided on the installation groove, and the locking pin matches the locking slot.
[0009] Furthermore, in order to drive the drill bit to rotate at high speed, one end of the mounting slot is connected to the output end of the drive motor, and the drive motor is mounted on the fixed plate.
[0010] Furthermore, in order to fix the drill bit, a first mounting plate is provided on the outside of the mounting block, and a second mounting plate is provided at the bottom of the mounting groove. The first mounting plate and the second mounting plate are connected by bolts.
[0011] Furthermore, in order to enhance the stability of the dust hood and prevent it from rotating during the dust collection process, a fixing post is provided on the outside of the dust hood, and one end of the fixing post is connected to the fixing plate by bolts.
[0012] Furthermore, the output end of the drive motor is connected to the fixed plate via a second bearing.
[0013] Furthermore, a retaining ring is fixedly connected inside the dust hood, and the retaining ring is connected to the first bearing.
[0014] The beneficial effects of this utility model are as follows:
[0015] (1) By installing a dust collection hood on the outside of the drill bit body, the dust collection hood can directly cover the working area of the drill bit. When the drill bit is working, by starting the exhaust fan, not only can the debris and dust generated during the drilling process be effectively collected, ensuring that the processing area is always clean, but the wear of debris on the drill bit can also be reduced, thereby extending the service life of the drill bit. This can effectively improve drilling quality and efficiency and reduce production costs.
[0016] (2) By connecting the dust collection hood to the drill bit body through the first bearing, the dust collection hood can remain stable when the drill bit body is rotating, ensuring that the dust collection hood always covers the working area of the drill bit and effectively collects the generated debris and dust.

[0024] 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.
[0025] According to an embodiment of the present invention, a drill bit for reaming holes in a drilling rig is provided.
[0026] Example 1
[0027] like Figures 1-4As shown, the drill bit for enlarging holes in a drilling rig according to an embodiment of the present invention includes a drill bit body 1. A dust collection hood 2 is connected to the top of the drill bit body 1 via a first bearing 20. A connector 3 is provided at the top of the dust collection hood 2, and the connector 3 is connected to a dust collection pipe 4. By providing the connector 3, it is convenient to separate and reconnect the dust collection hood 2 and the dust collection pipe 4. One end of the dust collection pipe 4 is connected to a collection box 5. A filter screen 6 is provided inside the collection box 5. The filter screen 6 is removable, which is convenient for users to clean. One side of the collection box 5 is connected to an exhaust fan 7. A fixing ring 19 is fixedly connected inside the dust collection hood 2. The fixing ring 19 is fixedly connected to the first bearing 20. A fixing post 18 is provided on the outside of the dust collection hood 2. One end of the fixing post 18 is connected to a fixing plate 15 by a bolt. Through the above scheme, during the use of the drill bit body 1, by starting the exhaust fan 7, the negative pressure generated by the exhaust fan 7 will be transmitted to the inside of the dust collection hood 2 through the dust suction pipe 4, so that the debris and dust generated during the drilling process can enter the collection box 5 along the dust suction pipe 4, thereby achieving effective collection of debris and dust generated during the drilling process. In addition, by setting the filter screen 6, dust is prevented from being discharged through the air outlet of the exhaust fan 7, ensuring a clean and safe working environment. Furthermore, the dust collection hood 2 is connected to the drill bit body 1 through the first bearing 20 and to the fixed plate 15 through the fixed stake 18, which can ensure the stability of the dust collection hood 2 when the drill bit body 1 rotates. Moreover, the first bearing 20 and the fixed stake 18 also have a certain shock absorption effect, which can absorb the vibration generated by the drill bit during operation and improve the stability of the drill bit.
[0028] Please see Figures 1-4A mounting block 8 is fixedly connected to the top of the drill bit body 1. A mounting groove 9 is provided above the mounting block 8, matching the mounting block 8. A recess 10 is provided inside the mounting block 8, and a spring 11 is installed inside the recess 10. One end of the spring 11 is connected to the mounting block 8, and the other end is connected to a locking post 12. A locking slot 13 is provided on the mounting groove 9, matching the locking post 12. One end of the mounting groove 9 is connected to the output end of a drive motor 14, which is mounted on a fixed plate 15. A first mounting plate 16 is provided on the outside of the mounting block 8, and a second mounting plate 17 is provided at the bottom of the mounting groove 9. The first mounting plate 16 and the second mounting plate 17 are connected by bolts. The output end of the drive motor 14 is connected to the fixed plate 15 via a second bearing. With this design, when installing the drill bit body 1, the mounting block 8 can be placed inside the mounting groove 9. By rotating the drill bit body 1, the locking post 12 on the mounting block 8 will gradually move closer to the locking slot 13 in the mounting groove 9 under the action of the spring 11. When the chuck 12 aligns with the slot 13, the spring 11 pushes the chuck 12 to automatically engage inside the slot 13. Once the chuck 12 is engaged, the drill bit body 1 is initially positioned and secured. At this point, the drill bit body 1 is essentially installed and will not move easily. After initial positioning and securing, the bolts can be installed more easily. The bolts further secure the drill bit body 1, ensuring it will not loosen or fall off during operation.
[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, a dust collection hood 2 is installed on the outside of the drill bit body 1. The dust collection hood 2 can directly cover the working area of the drill bit. When the drill bit is working, by activating the exhaust fan 7, not only can the debris and dust generated during the drilling process be effectively collected, ensuring that the processing area is always kept clean, but the wear of debris on the drill bit can also be reduced, thereby extending the service life of the drill bit. This can effectively improve drilling quality and efficiency, reduce production costs, and by connecting the dust collection hood 2 to the drill bit body 1 through the first bearing 20, ensure that the dust collection hood 2 remains stable when the drill bit body 1 rotates, ensuring that the dust collection hood 2 always covers the working area of the drill bit and effectively collects the generated debris and dust.
