Description
Technical field
The present invention relates to deburring tool field, especially a kind of cross-hole deburring cutter.
Background technique
In machining, especially on hydraulic valve, it will usually encounter two holes for intersecting processing, the infall in hole
Harmful burr can be generated, the presence of burr has seriously affected the processing quality of workpiece, reduced the service performance of workpiece.It is existing
Deburrer mostly both for drilling exit surface be plane cutter, set even for deburring at cross bore
The cutter of meter, cutting edge are generally linear type, are mostly absorbed in the burr generated at two holes to intersect vertically, and cutter knot
Structure is complicated.For two holes of mutual oblique, the position for generating burr is complex-shaped, is difficult to remove using above-mentioned deburrer dry
Only, it is difficult to reach ideal deburring effect.
Summary of the invention
In order to overcome existing deburrer, structure is complicated, and is difficult to the complex shape for being suitable for generating at oblique entry
The burr of shape, the present invention provide deburrer at a kind of cross bore, which can effectively remove the friendship of two inclined holes
The burr generated at fork.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of cross-hole deburring cutter, including cutter head and knife bar；The cutter head is spherical structure, around cutter spindle on cutter head
Several chip pockets are evenly distributed on line.
Further, the chip pocket offers main cutting edge and end cutting edge.
Further, the main cutting edge and end cutting edge are arc milling sword.
Further, there are angle α between chip pocket and knife bar, α value is 160~170 °.
Further, the maximum gauge of the knife bar is less than tool bit diameter.
Further, the maximum gauge of the cutter head is less than the inside aperture of the part of deburring.
Further, the cutter head and knife bar are monolithic construction.
Further, there are three the chip pockets.
Beneficial effects of the present invention:
1. the cutter head of bulb shape and the cutting edge of arc can be bonded well at inclined hole infall irregular shape
The burr of generation is conducive to effectively remove flash removed, and structure is simple, manufacture and use easy to process.
2. knife bar is mounted on lathe knife handle, when rotating clockwise around main shaft, end cutting edge is to the burr generated at aperture 7
It is handled, when spindle axis counterclockwise rotation, main cutting edge participates in cutting, and cutting-tool's used life can be improved in this way, reduces
The cost of charp tool.

Specific embodiment
To be understood the present invention is further, present invention will be further explained below with reference to the attached drawings and examples:
In conjunction with attached drawing 1, specifically, in the present embodiment, cutter head 1 and knife bar 2 are monolithic construction.
In conjunction with attached drawing 2, specifically, in the present embodiment, the shape of cutter head 1 be it is spherical, it is equal around 2 axis of knife bar on cutter head 1
There are three chip pocket 3, spherical cutter heads, for the effect that the burr in removal cross bore has had, because for intersecting for even distribution
For hole, burr is mainly attached to datum hole and intersection hole is mutually communicated place, and the shape at datum hole and the intersection hole place of being mutually communicated is
Complicated three-dimensional curve, spherical cutter head and arc milling sword have been well adapted for this complicated three-dimensional curve, Ke Yiyou
The removal of effect ground is attached to the burr of two hole intersections.
In conjunction with attached drawing 3, specifically, in the present embodiment, main cutting edge 4 and end cutting edge is distributed on each chip pocket 3
5, main cutting edge 4 and end cutting edge 5 are arc milling sword.
Specifically, in the present embodiment, the angle α between chip pocket 3 and knife bar 2 is preferably 160~170 °.When α value
At 160~170 °, effective cutting edge length can be kept；When less than 160 °, cutting edge length is too short；When greater than 170 °,
Cutting edge is almost parallel with knife bar axis, and when a cutting edge works, another cutting edge can hinder deburring process.
Specifically, in the present embodiment, the maximum gauge of knife bar 2 is less than 1 diameter of cutter head.
Specifically, in the present embodiment, the maximum gauge of cutter head 1 is less than the inside aperture of the part of deburring.
Specifically, in the present embodiment, knife bar 2 is mounted on lathe knife handle, when being rotated clockwise around main shaft, end cutting edge
The burr generated at 5 pairs of apertures 7 is handled, and when spindle axis counterclockwise rotation, main cutting edge 4 participates in cutting, can be mentioned in this way
High cutting-tool's used life reduces the cost of charp tool, is not limited to this kind of rotation mode, as long as realizing that main cutting edge is with end cutting edge
Use respectively.
It is the structural schematic diagram of tool sharpening cross bore of the present invention in conjunction with attached drawing 4, cutter of the present invention can not only remove friendship
Burr in entry can also remove the burr in common circular hole.
Deburrer of the present invention is completed after deburring from center withdrawing from drill center feed, in this way can be to avoid damage
The surface in bad machined hole guarantees part processing quality and technique requirement, when cutter removes flash removed, in addition to around own axes
It outside rotary motion, is also rotated around motion profile 8 as shown in FIG. 6, when Fig. 5 is that deburring works, cutter is relative to hole
One position of axis.
Although specific embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is
Illustratively, it is not considered as limiting the invention, those skilled in the art within the scope of the invention can be right
Above-described embodiment is changed, modifies, replaces and adjusts.
The embodiment is a preferred embodiment of the present invention, but present invention is not limited to the embodiments described above, not
In the case where substantive content of the invention, any conspicuous improvement that those skilled in the art can make, replacement
Or modification all belongs to the scope of protection of the present invention.
