Abstract
The utility model discloses a kind of high-precision Woodworking flat drills.It includes by drillstock, the chit drill ontology that the segment of cutting that flat linkage section and linkage section hypomere are formed is constituted, the segment of cutting of chit drill ontology includes the cutting edge portion that linkage section hypomere side section shape is isosceles triangular structure and the positioning apex point that cutting edge portion end is formed, the tow sides of positioning apex point are both provided with tip cutting edge, the both sides of cutting edge portion are provided with the cutting tooth that cross sectional shape is zigzag structure, the lower end of linkage section is provided with positioned at two trimming tips of cutting edge portion both sides, trimming tip is connect with cutting edge portion transition, it is provided with trimming sword on trimming blade.With the above structure, stock-removing efficiency can be greatly improved by the cutting edge of the arc, it is time saving and energy saving when cutting, the workpiece after punching is rebuild by rebuilding sword simultaneously, the precision that ensure that punching substantially increases processing quality, reasonable in design, process efficient and convenient, high in machining efficiency and processing quality is good.
Description
Technical field
The utility model is related to a kind of machining tool, specifically a kind of high-precision Woodworking flat drill.
Background technology
Existing Woodworking flat drill generally comprises the flat cutting head connected on drillstock and drillstock, and there have in cutting head to be fixed
Position apex point, the both sides for positioning apex point are provided with oppositely arranged cutting blade, and existing this structure can realize boring requirement,
But due to the limitation of its structure design, on the one hand, be difficult to continue deeper into and pierce when drilling is to half, needed it
It takes out and pierces again, this mode is time-consuming, still further aspect, in the boring procedure so that outer surface of drill bit and table in drilling
Face phase mutual friction causes drilling circularity cannot be guaranteed so that processing quality is poor.
Invention content
The technical problem to be solved by the utility model is to provide it is a kind of it is easy to use it is laborsaving, drilling quality is good and drilling is imitated
The high high-precision Woodworking flat drill of rate.
In order to solve the above-mentioned technical problem, the high-precision Woodworking flat drill of the utility model includes by drillstock, flat connection
The chit drill ontology that the segment of cutting that section and linkage section hypomere are formed is constituted, the segment of cutting of chit drill ontology includes linkage section hypomere
Side section shape is the cutting edge portion of isosceles triangular structure and the positioning apex point that cutting edge portion end is formed, and positions apex point
Tow sides be both provided with tip cutting edge, the both sides of cutting edge portion are provided with the cutting tooth that cross sectional shape is zigzag structure,
The lower end of linkage section is provided with positioned at two trimming tips of cutting edge portion both sides, and trimming tip is connect with cutting edge portion transition,
Trimming is provided with trimming sword on tip.
The trimming sword includes being located at the interior trimming sword on the inside of trimming tip and the outer trimming sword on the outside of trimming tip,
The interior trimming sword can be used as assisted machining sword, outer trimming sword that can be used as outer finishing sword.
The chit drill ontology is made of high-speed tool Steel material.
After above-mentioned structure, since the both sides of cutting edge portion are provided with the cutting tooth that cross sectional shape is zigzag structure
And the trimming tip with trimming sword of the lower end setting of linkage section, it can be carried significantly from there through the cutting edge of the arc
High stock-removing efficiency, and while cutting, is time saving and energy saving, while the workpiece after punching is rebuild by rebuilding sword, it ensure that punching
Precision, substantially increase processing quality, it is reasonable in design, processing it is efficient and convenient, high in machining efficiency and processing quality is good.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model high-precision Woodworking flat drill.
Specific implementation mode
With reference to the accompanying drawings and detailed description, the high-precision Woodworking flat drill of the utility model is made further specifically
It is bright.
As shown, the high-precision Woodworking flat drill of the utility model, includes by drillstock 1, flat linkage section 2 and connection
The chit drill ontology 4 that the segment of cutting 3 that section hypomere is formed is constituted, described chit drill ontology 4 preferentially use high-speed tool Steel material system
Segment of cutting at, chit drill ontology 4 include the cutting edge portion 5 that linkage section hypomere side section shape is isosceles triangular structure with
And the positioning apex point 6 that cutting edge portion end is formed, the tow sides of positioning apex point 6 are both provided with tip cutting edge, cutting edge portion 5
Both sides are provided with the cutting tooth that cross sectional shape is zigzag structure, and the lower end of linkage section 2 is provided with positioned at 5 both sides of cutting edge portion
Two trimming tips 9, trimming tip 9 are connect with 5 transition of cutting edge portion, are rebuild on tip 9 and are provided with trimming sword 10, rebuild sword 10
Include the outer trimming sword positioned at the interior trimming sword of 9 inside of trimming tip and positioned at 9 outside of trimming tip, the interior trimming sword can
As assisted machining sword, outer trimming sword can be used as outer finishing sword.
