Abstract
The utility model discloses a kind of improved woodwork processing straight knife, the shank section being connected including cutter head portion and with cutter head portion rear end, wherein, the maximum outside diameter of described cutter head portion rear end is identical with the external diameter of shank section, in the shank section at least 1 annular groove is provided with by knife head side, one opening snap ring, the external diameter of the external diameter more than shank section of the opening snap ring are installed in described annular groove.A kind of improved woodwork processing straight knife of the present utility model has that processing cost is low, production efficiency is high, using it is flexible the characteristics of.
Description
Technical field
The utility model is related to a kind of cutter, more specifically, more particularly to a kind of improved woodwork processing straight knife.
Background technology
In woodwork processing now, straight knife is one of widely used cutter product.Existing straight knife structure
As shown in figure 1, being made up of cutter head portion 10 and the shank section 20 being connected with the rear end of cutter head portion 10, the external diameter of the rear end of cutter head portion 10 is more than
The external diameter of shank section 20, when using, in putting shank section 20 into chuck, because the rear end external diameter of cutter head portion 10 is more than shank section 20
External diameter, makes the rear end of cutter head portion 10 and chuck ends contact, to support the effect of fixed cutter body.Due to the cutter head portion of existing straight knife
The external diameter of 10 rear ends needs to use the workpiece using the external diameter in cutter head portion 20 as external diameter in processing more than the external diameter of shank section 20
Blank, the shape according still further to straight knife mills out cutter head portion and the shank section of cutter hub respectively, exist many manufacturing procedures, long processing time,
The big shortcoming of spillage of material, also add production cost.And, the depth that the shank section of straight knife puts chuck into is relatively fixed, no
The insertion depth of shank section can be adjusted, cutter uses underaction, it is impossible to meet process requirements.Therefore, how further
The structure of straight knife is improved, to reduce processing cost, accelerate production efficiency, raising process velocity, and using more flexibly, is turned into
The new direction of straight knife development.
Utility model content
The purpose of this utility model is to provide a kind of improved woodwork processing straight knife, and this kind of straight knife has and be processed into
This low, production efficiency is high, using it is flexible the characteristics of.
The technical solution adopted in the utility model is as follows：
A kind of improved woodwork processing straight knife, including cutter head portion and the shank section that is connected with cutter head portion rear end, wherein,
The maximum outside diameter of described cutter head portion rear end is identical with the external diameter of shank section, and at least 1 is provided with by knife head side in the shank section
Bar annular groove, is provided with an opening snap ring in described annular groove, and the external diameter of the opening snap ring is big
In the external diameter of shank section.
Further, 2~3 annular grooves are sequentially provided with by knife head side in the shank section.
Further, adjacent two annular groove spacing distances are 3~4mm.
Further, the width of the annular groove is 1~1.1mm, and depth is 0.6~0.8mm.
Compared with prior art, the utility model have the advantage that for：
A kind of improved woodwork processing straight knife of the present utility model, including cutter head portion and be connected with cutter head portion rear end
Shank section, wherein, the maximum outside diameter of described head rear end is identical with the external diameter of shank section, is provided with by knife head side in shank section
At least 1 annular groove, is provided with an opening snap ring in annular groove, and the external diameter of the snap ring that is open is more than handle of a knife
The external diameter in portion.The workpiece blank that straight knife of the present utility model only needs to the external diameter for using external diameter to be equal to shank section is processed, Neng Goujie
About blank, reduce cost of material；In processing, it is not necessary to carry out unnecessary working process to the corresponding shank section position of blank, directly
Processing cutter head portion is met, production efficiency is higher；At least 1 annular groove is provided with by knife head side in shank section, by the bullet that is open
Property snap ring is buckled in annular groove, and shank section is fixed in chuck using snap ring；Can be changed using a plurality of annular groove
Shank section inserts the depth of chuck, and cutter uses more flexible.
Brief description of the drawings
Fig. 1 is the structural representation of traditional straight knife；
Fig. 2 is structural representation of the present utility model；
Fig. 3 is mounting structure schematic diagram of the present utility model.
Specific embodiment
With reference to specific embodiment, the technical solution of the utility model is described in further detail, but not structure
Paired any limitation of the present utility model.
Shown in reference picture 2 and Fig. 3, a kind of improved woodwork processing straight knife of the present utility model, including the He of cutter head portion 1
The shank section 2 being connected with the rear end of cutter head portion 1, wherein, the maximum outside diameter of the described rear end of cutter head portion 1 and the external diameter phase of shank section 2
Together, at least 1 annular groove 3 is provided with by the side of cutter head portion 1 in the shank section 2, one is provided with described annular groove 3
Opening snap ring 4, the external diameter of the external diameter more than shank section 2 of the opening snap ring 4.One kind of the present utility model is improved
Woodwork processing straight knife, because the maximum outside diameter in cutter head portion 1 is identical with the external diameter of shank section 2, so it is only necessary that using external diameter
Equal to the workpiece blank processing of the external diameter of shank section 2, blank can be saved, cost of material is reduced；In processing, it is not necessary to base
Expect that the position of corresponding shank section 2 carries out unnecessary working process, directly process cutter head portion 1, the more existing straight knife structure of manufacturing procedure
Simpler, production efficiency is higher；In process, at least 1 annular groove 3 is provided with by knife head side in shank section 1, is made
Used time, by opening snap ring 4 buckle wherein an annular groove 3, using opening snap ring 4 by shank section 2
It is fixed in chuck, to realize that the alignment to cutter is positioned；In the shank section 2 a plurality of annular groove is provided with by the side of cutter head portion 1
3, opening snap ring 4 is buckled on different annular grooves 3, thus it is possible to vary shank section 2 inserts the depth of chuck, cutter makes
With more flexible.
2~3 annular grooves 3 are sequentially provided with by the side of cutter head portion 1 in the shank section 2, shank section 3 is had 2 when inserting chuck
Or 3 kinds of different depth, it is capable of the use of more easily cutter.
It is 3~4mm by adjacent two annular groove spacing distances according to the use requirement of general engineered wood product, can be more
Convenient use.
The width of the annular groove 3 is 1~1.1mm, and depth is 0.6~0.8mm, by the width and depth of annular groove 3
Degree is arranged in this value range, and opening snap ring 4 can be made preferably to be fixed in annular groove 3, makes opening snap ring 4
Fixation is easily contacted with chuck.
The foregoing is only preferred embodiment of the present utility model, all institutes in spirit of the present utility model and spirit
Any modification, equivalent and improvement for making etc., should be included within protection domain of the present utility model.
