Description

High-speed drill bit structure of circuit board drill bit

Technical Field

The utility model relates to a drill point technical field specifically is a high-speed drill bit structure of circuit board drill point.

Background

The drill is a tool for drilling through holes or blind holes in solid materials and reaming existing holes. Commonly used drill bits mainly include twist drills, flat drills, center drills, deep hole drills, and trepanning drills. Reamers and reamers are not capable of drilling solid materials, but they are also traditionally classified as drills.

At present, the skew takes place easily during current drill bit centering, and centering effect is not good to current drill bit structural design is unreasonable, often can block up the helicla flute of drill bit with the piece at the in-process that punches at the in-process of punching, has influenced the cutting process effect from this.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high-speed drill bit structure of circuit board drill point to take place the skew easily when solving current drill bit centering, the not good problem of centering effect.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a high-speed drill bit structure of circuit board drill point, includes the drill bit, the surface of drill bit is equipped with the helicla flute, the surface of helicla flute is equipped with the chip groove, the one end side of drill bit is equipped with the center location drill point, the surface of center location drill point is equipped with the multiunit sawtooth.

Preferably, the centre locating drill tip is conical.

Preferably, the length of each sawtooth is one millimeter.

Preferably, the side of one end of the drill bit is welded with an installation rod, and the surface of the installation rod is provided with a positioning groove.

Preferably, the mounting rod is in the shape of a rhomboid column.

Compared with the prior art, the beneficial effects of the utility model are that: the high-speed drill bit structure of the circuit board drill bit can increase the cutting capacity of the center positioning drill tip through the saw teeth, so that the center positioning drill tip can quickly drill into a workpiece, the drill bit is positioned, and the condition of drilling deviation is avoided; the piece can be followed and discharged in the chip groove, avoids appearing the condition that the piece blockked up the helicla flute.

Drawings

FIG. 1 is a front view of the overall structure of the present invention;

fig. 2 is a side view of the overall structure of the present invention.

In the figure: 1 drill bit, 2 spiral grooves, 3 chip grooves, 4 center positioning drill points, 5 sawteeth, 6 mounting rods and 7 positioning grooves.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1, a high-speed drill structure of a circuit board drill nozzle includes a drill bit 1, a spiral groove 2 is formed on a surface of the drill bit 1, a chip discharge groove 3 is formed on a surface of the spiral groove 2, chips are taken out along the spiral groove 2 during drilling, and are thrown away when the chips move to the chip discharge groove 3 along the spiral groove 2 due to the fact that the drill bit 1 is in a high-speed rotating state, a center positioning drill tip 4 is arranged on a side surface of one end of the drill bit 1, a plurality of groups of saw teeth 5 are formed on a surface of the center positioning drill tip 4, and the saw teeth 5 can increase cutting capacity of the center positioning drill tip 4, so that the center positioning drill tip 4 can quickly drill into a workpiece during rotation, and accordingly positioning effect is achieved.

Referring to fig. 1, the center positioning drill tip 4 is conical.

Referring to fig. 1, the length of the saw teeth 5 is one millimeter, the saw teeth 5 are easily damaged when drilling, and the cutting ability of the saw teeth 5 is reduced when the saw teeth are too short.

Referring to fig. 1, an installation rod 6 is welded on a side surface of one end of the drill bit 1, a positioning groove 7 is formed in the surface of the installation rod 6, the installation rod 6 can be conveniently installed and positioned through the positioning groove 7, and the situation that the drill bit 1 falls off is avoided.

Referring to fig. 2, the mounting rod 6 has a triangular prism shape.

The utility model discloses when concrete implementation: when using, because the surface of center location drill point 4 is equipped with multiunit sawtooth 5, can increase the cutting ability of center location drill point 4, make center location drill point 4 bore into the work piece fast in, thereby fix a position drill bit 1, avoid appearing the condition of drilling skew, when drilling, the piece is taken out along helicla flute 2, because drill bit 1 is in high-speed pivoted state, when the piece moves chip groove 3 along helicla flute 2, the piece can be thrown away, make the piece discharge in can following chip groove 3, avoid appearing the condition that the piece blockked up helicla flute 2.
