Abstract
The utility model provides a kind of timber deep hole processing chit drill, including drillstock and cutting head, the cutting head includes two symmetrically arranged fan-shaped cutting blocks, the a side of two fan-shaped cutting blocks structures in line is equipped with the cutting edge of raised side height, and the center of cutting edge is arranged in horn structure；The outer end of another side of described two fan-shaped cutting blocks, which is equipped with, thickeies cutting edge.Utility model has the advantages that the utility model timber deep hole processing chit drill, change the composite structure that Double-blade structure is fan-shaped cutting blocks and cutting edge, multiple cutting head punching meeting speed is faster, it cuts sharper, and fan-shaped cutting block structure increases drilling circularity, meanwhile it can guarantee uniform force in cutting process, and then guarantee cutting precision.
Description
Technical field
The utility model relates to a kind of boring bar tool, in particular to a kind of timber deep hole processing chit drill.
Background technique
Timber chit drill is mainly used for timber deep hole processing, and current chit drill mostly uses greatly Double-blade structure, and cutting is not sharp, often
The phenomenon that often hardwood occur beats motionless problem, and during the cutting process due to discontinuity, often will appear offset causes to add
The shape that work comes out deforms, and subsequent also to be finished, the precision and production efficiency of processing be not high.In addition, making at present
The chit drill of Double-blade structure in turn results in timber deep hole processing with flat there is also the problem that cutting resistance is big and chip removal is unsmooth
Bore the low defect of service life.
Therefore, research and develop that a kind of to cut timber deep hole processing that is sharp and can be improved trepanning velocity with chit drill be that have very much must
It wants.
Utility model content
Timber that is sharp and can be improved trepanning velocity is cut the technical problem to be solved by the present invention is to provide a kind of
Deep hole processing chit drill.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of timber deep hole processing chit drill, including
Drillstock and cutting head；Its innovative point is: the cutting head includes two symmetrically arranged fan-shaped cutting blocks, two fan-shaped cutting blocks
The a side of structure in line is equipped with the cutting edge of raised side height, and the center of cutting edge is arranged in horn structure；Institute
The outer end for stating another side of two fan-shaped cutting blocks, which is equipped with, thickeies cutting edge.
Further, ring limit block is equipped in the outer lower end of described two fan-shaped cutting blocks.
Utility model has the advantages that
(1) the utility model timber deep hole processing chit drill changes the group that Double-blade structure is fan-shaped cutting blocks and cutting edge
Structure is closed, faster, cutting is sharper for multiple cutting head punching meeting speed, and fan-shaped cutting block structure increases the circularity that drills, meanwhile,
It can guarantee uniform force in cutting process, and then guarantee cutting precision；
(2) the utility model timber deep hole processing chit drill is equipped with ring limit block in the outer lower end of two sectorial blocks, can
Effective controlling depth cutting face is smooth.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model timber deep hole processing chit drill.
Specific embodiment
The following examples can make professional and technical personnel that the utility model be more fully understood, but therefore will not
The utility model is limited among the embodiment described range.
Embodiment
The present embodiment timber deep hole processing chit drill, as shown in Figure 1, including drillstock 1 and cutting head 2；Cutting head 2 includes two
A symmetrically arranged fan-shaped cutting blocks 21, a side of two 21 structures of fan-shaped cutting blocks in line are equipped with raised side height
Cutting edge 22, and the center of cutting edge 22 is arranged in horn structure；The outer end of another side of two fan-shaped cutting blocks 21, which is equipped with, to be added
Thick cutting edge 23, and it is equipped with ring limit block 24 in the outer lower end of two fan-shaped cutting blocks 21, deep cuts face can be effectively controlled
Smoothly.
The present embodiment timber deep hole processing chit drill changes the combination knot that Double-blade structure is fan-shaped cutting blocks 21 and cutting edge
Structure, faster, cutting is sharper for multiple cutting head punching meeting speed, and fan-shaped cutting block structure increases the circularity that drills, meanwhile, it can protect
Uniform force in cutting process is demonstrate,proved, and then guarantees cutting precision.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.This
The technical staff of industry is retouched in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
That states only illustrates the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model
It will also have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.This is practical new
Type is claimed range and is defined by the appending claims and its equivalent thereof.
