Description
Technical field
The utility model is related to a kind of drill bit of drilling, especially a kind of precision machined drill bit.
Background technology
In architectural engineering, electric drill is a kind of common tool, and user can be operated by electric power motor, promote drill bit
Quickly rotation, is punched, subsequently to carry out other operations.During this, hole depth is an important parameter, needs basis
Specific requirements are specifically adjusted.
Existing electric drill, user usually substantially predict to be drilled by estimating the naked the length of the bit for being exposed on the external space
The depth in hole, but this kind of mode accuracy is low, needs adjustment of constantly stopping work, inefficiency, and dust is flown upward in boring work,
User's sight is hindered, drilling quality is influenced.
Utility model content
The utility model is for high, the drill bit of the good tape identification of drilling quality that provides a kind of drilling precision.
To achieve the goals above, the utility model provides a kind of precision machined drill bit, including drill bit, and drilling rod is gone back
Including spacing ring and spacer pin, several marks are equipped on the drilling rod between setting cutting edge, the gap of the cutting edge,
The mark forms the axially vertical visible scale of drilling rod together in bit on drilling rod；
The drilling rod top is equipped with limit hole, and the spacer pin is mounted in limit hole, and the spacing ring passes through spacer pin
On drilling rod；
Symmetrical LED spotlight is set on the spacing ring, and the light directive of the LED spotlight is directed toward drill bit position.
Further, the limit hole is horizontally disposed square through hole, and the limit hole passes through the vertical center of drilling rod
Line.
Further, the shape of the spacer pin is rectangle strip, the cross sectional shape of the spacer pin and limit hole
Cross sectional shape coincide.
Further, the shape of the spacing ring is annulus row, and the internal diameter of the spacing ring is slightly larger than the diameter of drilling rod, institute
The switch that spacing ring is equipped with control LED spotlight is stated, and the power supply being connect with switch and LED spotlight.
Further, described to be identified as colour, the mark is around radial one week part of drilling rod peripheral surface.
Further, the spacing distance between the mark is identical.
The advantageous effect that the utility model is reached：By in the identical mark in the multiple intervals of drilling rod upper cutting edge gap setting
Know, makes user when using drill bit, can intuitively know that drill bit enters the depth of wall part, to carry out hole depth
Prediction or fine tuning, improve perforating efficiency；In use, LED spotlight light direct projection boring sites in curing reduces drilling dust to regarding
The influence of line facilitates adjustment bore angle, is also convenient for seeing clearly the mark on drilling rod, adjusts drilling depth, improves borehole accuracy.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structure enlargement diagram at A.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating this
The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
As shown in Figure 1, 2, a kind of precision machined drill bit, including drill bit 1 are present embodiments provided, drilling rod 2 further includes limit
Position ring 3 and spacer pin 4 is equipped with several marks 6 on the drilling rod 2 between setting cutting edge 5, the gap of the cutting edge 5,
The mark 6 forms the axially vertical visible scale of drilling rod together when drill bit 1 is rotated on drilling rod 2；
2 top of the drilling rod is equipped with limit hole 7, and the spacer pin 4 is mounted in limit hole 7, and the spacing ring 3 passes through limit
Position pin 4 is mounted on drilling rod 2；
Symmetrical LED spotlight 8 is set on the spacing ring 3, and the light directive of the LED spotlight 8 is directed toward drill bit position.
The limit hole 7 is horizontally disposed square through hole, and the limit hole 7 passes through the vertical centerline of drilling rod.
The shape of the spacer pin 4 is rectangle strip, the cross sectional shape of the spacer pin 4 and the section shape of limit hole 7
Shape coincide.
The shape of the spacing ring 6 is annulus row, and the internal diameter of the spacing ring 6 is slightly larger than the diameter of drilling rod 5, the limit
Ring 3 is equipped with the switch of control LED spotlight 8, and the power supply being connect with switch and LED spotlight 8.
The mark 6 is colour, and adjacent mark 6 is arranged using different colors, and the mark 6 is around drilling rod periphery face diameter
To one week part.
Spacing distance between the mark 6 is identical, and the mark 6 of different colours represents the scale of design.
This implementation opens the switch of LED spotlight in use, drilling rod tail portion is connected on drilling machine, adjusts bore position, into
Row drilling.
The present embodiment is by the way that in the identical mark in the multiple intervals of drilling rod upper cutting edge gap setting, user is using drill bit
When, it can intuitively know that drill bit enters the depth of wall part, to carry out hole depth prediction or fine tuning, improve punching
Efficiency；In use, LED spotlight light direct projection boring sites in curing reduces influence of the drilling dust to sight, adjustment is facilitated to drill
Angle is also convenient for seeing clearly the mark on drilling rod, adjusts drilling depth, improves borehole accuracy.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
