Technical field

The utility model is related to special type knife field, especially a kind of locations of contours knife.

Background technology

Milling cutter is the rotary cutter for Milling Process, with one or more cutters tooth.When work each cutter tooth successively between Cut the surplus of workpiece with having a rest.Milling cutter is mainly used for processing plane, step, groove, forming surface and cut-out workpiece on milling machine Deng.Milling cutter is generally the workpiece for processing specific shape and specially manufactures and designs, and is commonly used for machining angle face, groove surface, spy Different shape hole and step surface etc., the blade type that milling cutter cuts cutting edge is generally adapted with the shape of workpiece, in order to pass through time processing Required specific shape is formed on workpiece.One product of processing needs to use much knives tool, multiple clamping, clamping in previous Shi Hou needs to generate tool-setting error to knife, along with complicated numerical control programming, to improving production efficiency and ensureing product quality All unfavorable, therefore, it is necessary to design a kind of locations of contours knife.

Utility model content

In order to overcome the defects of the prior art, a kind of locations of contours knife is provided.

The utility model is realized by following proposal：

A kind of locations of contours knife, including handle of a knife, cutter head extend a positioning coaxial with handle of a knife in front of the cutter head Bar, the locating rod are equipped with the positioning bead for protruding from its surface, the snap ring of annular groove shape are also correspondingly provided on the handle of a knife.

Preferably, the positioning bead is set to the front end of locating rod and is an integral structure with locating rod, the positioning bead Maximum outer profile width be to position 1.1-1.6 times of shank diameter, eccentricity is 0.02 micron, and the cutter angle of spread is 115 °.

Preferably, the cutter head is equipped with two or more cutting edges, and each cutting edge is uniformly divided with identical phase difference It is distributed in the cutter head surrounding.

Preferably, the cutting edge is two and is centrosymmetric with the axis of handle of a knife.

Preferably, the angle of shear at the cutting edge outer rim is 3 °.

Preferably, the gash angle of the cutting edge is 40 °.

The beneficial effects of the utility model are：

A kind of front end of locations of contours knife of the utility model is to position to use to knife, reduces error when repeated clamping, makes It is more accurate to knife every time；Intermediate snap ring is when ensureing tool sharpening product, its more preferable radian of bounce is small, and the beat of cutter is more It is small, it ensure that the chucking power of cutter clamping is more preferable.

Fig. 2 is the end view drawing of Fig. 1；

Fig. 3 is the A-A cutaway view Amplified images of Fig. 1；

Fig. 4 is the B-B cutaway view Amplified images of Fig. 1.

Specific implementation mode

The utility model preferred embodiment is further illustrated below in conjunction with the accompanying drawings：

As shown in Figs. 1-3, a kind of locations of contours knife, including handle of a knife 1, cutter head 2, the front of the cutter head 2 extend one with The coaxial locating rod 3 of handle of a knife 1, the locating rod 3 are equipped with the positioning bead 5 for protruding from its surface, also corresponding on the handle of a knife 1 Snap ring 5 equipped with annular groove shape.This cutter is designed using straight trough, be ensure that the precision of product profile well, is facilitated life The stability in manufacturing process is produced, convenient for batch production.Front end is to position to use to knife, reduces error when repeated clamping, makes It is more accurate to knife every time.

Preferably, the positioning bead 4 is set to the front end of locating rod 3 and is an integral structure with locating rod, the positioning The maximum outer profile width of pearl 4 is 1.1-1.6 times of 3 diameter of locating rod, and in the present embodiment, positioning bead 4 is spherical shape, diameter D1 It it is 1.1-1.6 times of 3 diameter of locating rod, eccentricity is 0.02 micron, and the cutter angle of spread is 115 °, makes the more steady of tool grinding Fixed, profile feed is more accurate.The radius of positioning bead 4 is set according to the actual conditions of previous clamping,

Preferably, the cutter head 2 is equipped with two or more cutting edges 6, and each cutting edge 6 is uniform with identical phase difference It is distributed in the cutter head surrounding.

Preferably, the cutting edge is two and is centrosymmetric with the axis of handle of a knife.

Preferably, as shown in figure 3, the angle of shear at 6 outer rim of the cutting edge is 3 °, 3 degree of the angle of shear can make cutter It is sharper, grinding it is very smooth.

Preferably, as shown in figure 4, the gash angle of the cutting edge 6 is 40 °.

The radius of positioning bead is set according to actual conditions, previous, when being positioned to locations of contours knife, needs standard True clamping, so that the clamping distance in figure is met the requirements, after having positioning bead, direct clamping so that positioning bead is adjacent to workpiece Wall surface.

Although having done more detailed elaboration to the technical solution of the utility model and having enumerated, it should be understood that for For those skilled in the art, modification is made to above-described embodiment or uses equivalent alternative solution, this skill to this field Be for art personnel it is clear that on the basis of without departing from the spirit of the present invention these modifications or improvements, belong to In the range of the requires of the utility model protection.
