Abstract
The present invention relates to a kind of timber deep hole processing chit drills, including drillstock and cutting head, the cutting head includes two symmetrically arranged fan-shaped cutting blocks, and 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.The advantage of the invention is that：Timber deep hole processing chit drill of the present invention changes the composite structure that Double-blade structure is fan-shaped cutting blocks and cutting edge, and multiple cutting head punching meeting speed is faster, cut sharper, and fan-shaped cutting block structure increases drilling circularity, simultaneously, it can guarantee uniform force in cutting process, and then ensure cutting precision.
Description
Technical field
The present invention relates to a kind of boring bar tool, more particularly to a kind of timber deep hole processing chit drill.
Background technology
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 and beat 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 subsequently 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, it is that have very much must to research and develop a kind of timber deep hole processing sharp and that can improve trepanning velocity of cutting with chit drill
It wants.
Invention content
Timber processing sharp and that trepanning velocity can be improved is cut the technical problem to be solved in the present invention is to provide a kind of
Deep hole chit drill.
In order to solve the above technical problems, the technical scheme is that：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, and two fan-shaped cutting blocks are constituted
A side of one straight line is equipped with the cutting edge of raised side height, and the center of cutting edge is arranged in horn structure；Described two
The outer end of another side of fan-shaped cutting blocks, which is equipped with, thickeies cutting edge.
Further, it is equipped with ring limit block in the outer lower end of described two fan-shaped cutting blocks.
The advantage of the invention is that：
(1) timber deep hole processing chit drill of the present invention changes the combination knot that Double-blade structure is fan-shaped cutting blocks 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 ensures cutting precision；
(2) timber deep hole processing chit drill of the present invention is equipped with ring limit block in the outer lower end of two secter pats, can be effective
Controlling depth cutting face is smooth.
Description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of timber deep hole processing chit drill of the present invention.
Specific implementation mode
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be 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, it can effective controlling depth cutting face
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 ensures cutting precision.
The basic principles and main features and advantages of the present invention of the present invention have been shown and described above.The skill of the industry
Art personnel it should be appreciated that the present invention is not limited to the above embodiments, the above embodiments and description only describe
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
