Description

Technical Field

[0001] This utility model relates to the field of drill bit technology, specifically a drill bit structure that integrates drilling and polishing. Background Technology

[0002] Currently, the mold and automotive lighting industry is experiencing rapid product updates and iterations, with increasingly complex product designs emerging. Improving processing efficiency and controlling mold costs while meeting customer requirements has become a major challenge. Currently, after the mold drilling process is completed, the mold needs to be removed from the machine tool for separate polishing to ensure the quality of the holes. This multi-step operation is not only cumbersome but also results in a significant waste of human and material resources. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a drill bit structure that integrates drilling and polishing, enabling simultaneous drilling and polishing processes during use.

[0004] The technical solution is as follows: a drill bit structure integrating drilling and polishing, comprising a drill bit body, wherein a cutting blade is mounted on the drill bit body, the bottom of the cutting blade protruding from the bottom of the drill bit body for drilling chips, characterized in that: an installation groove is provided on the side of the drill bit body, a grinding blade is installed in the installation groove, and the grinding surface of the grinding blade protrudes from the side of the drill bit body for grinding and polishing the sidewall of the drilled hole.

[0005] Furthermore, the drill bit body has a cutting fluid channel inside, and a cutting fluid outlet is provided at the bottom of the drill bit body, which is connected to the cutting fluid channel.

[0006] Furthermore, the mounting groove is square and milled out by a milling cutter, with one end extending to the bottom of the drill bit body and the other end extending along the axial direction of the drill bit body. A process hole is provided at the corner of the other end to avoid the corner of the grinding blade.

[0007] Furthermore, the process hole is connected to the cutting fluid channel.

[0008] Beneficial effects: While drilling with cutting blades, grinding blades can polish the sidewalls of the hole, thus completing polishing at the same time as drilling, thereby reducing processes and improving processing efficiency; in addition, by setting up a slurry outlet, the cutting blades can be cooled, and the slurry discharged through the process hole can also cool the grinding blades. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0010] like Figure 1 The diagram shows a drill bit structure that integrates drilling and polishing. It includes a drill bit body 1, on which a cutting blade 2 is mounted by screws. The bottom of the cutting blade 2 protrudes from the bottom of the drill bit body 1 for drilling chips. A mounting groove is provided on the side of the drill bit body 1, and a grinding blade 3 is mounted in the mounting groove by screws. The grinding surface of the grinding blade 3 protrudes from the side of the drill bit body 1 and is used to grind and polish the sidewall of the drilled hole. In use, the whole assembly can be assembled on a drilling machine. The cutting blade 2 rotates with the drill bit body 1 to drill chips from the mold, and at the same time, the grinding blade 3 rotates with the drill bit body 1 to polish the hole synchronously, achieving the effect of mechanized drilling and polishing in one step.

[0011] Meanwhile, in order to prevent the cutting blade 2 from being scrapped due to high temperature during drilling, a cutting fluid channel is provided inside the drill bit body 1, and a cutting fluid outlet 4 is provided at the bottom of the drill bit body 1, which is connected to the cutting fluid channel.

[0012] In addition, the mounting slot for mounting the grinding insert 3 is square (to accommodate inserts that are typically square) and is milled out by a milling cutter. One end of the slot extends to the bottom of the drill body 1, allowing the milling cutter to enter from the bottom of the drill body 1 to mill the slot. The other end extends along the axial direction of the drill body 1, and a process hole 5 is provided at the corner of the other end to avoid the corner of the grinding insert. This is because the milling cutter cannot directly mill out a right angle during the feed process. In order to accommodate inserts with right angles on the periphery, two process holes can be milled outward to accommodate the right angle corner of the insert. Furthermore, the process hole 5 can be connected to the cutting fluid channel, so that the cutting fluid can be discharged through the process hole 5 to cool the grinding insert 3.

[0013] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
