The invention belongs to machining tool field, more particularly to a kind of five rib burnishing-in knife of taper for the finishing of cone seal hole.Five rib burnishing-in knife its burnishing-in sword of taper of the present invention is 5 straight ribs, and each straight rib with burnishing-in knife central axis at an angle, 5 straight ribs are on the same conical surface, and 5 straight rib sword sections are asymmetric pentagon.In addition, described 5 straight rib swords are divided into burnishing-in sword and finishing sword according to tread degree difference, burnishing-in sword is three, and finishing sword is two, is symmetrical arranged, and burnishing-in tread degree is more than finishing tread degree.The present invention is finished after existing straight sword or helical edge reamer slightly hinge, and five swords are not sharp, and support is uniform, can effectively avoid processor exert a force on hand it is uneven caused by the inclined phenomenon of hinge and hole wall axially have ditch phenomenon.
Description
Technical field
The invention belongs to machining tool field, more particularly to a kind of five rib of taper for the finishing of cone seal hole
Burnishing-in knife.
Background technology
In some housings that airplane engine fuel oil regulating system and hydraulic system use, there are cone blocking sealing structure.
The characteristics of cone blocking sealing structure is：1. the taper hole of certain gradient is processed in housing, it is desirable to which surface roughness is better than Ra0.8；
2. cone blocking is consistent with taper hole gradient, surface roughness is also superior to Ra0.8；3. being pounded cone blocking in taper hole using external force, occur
Plastic deformation, plays the role of sealing.
Processing of the in the market for such cone seal hole uses nonstandard taper reamer, similar with chucking reamer, have straight sword and
Two kinds of helical edges.But when hand reamer processes taper hole, although efficiency is higher, there are following two problems：1. fraising is coarse
Spend unstable, annular cut can be produced due to squeezing bits；2. by processor, force direction is influenced on hand, it may appear that is cut with scissors inclined phenomenon, is made
There is ditch vertically on into the conical surface, surface roughness is unqualified.
The processing of burnishing-in knife be it is a kind of using metal in the cold plasticity feature of normal temperature state, carry out burnishing-in without machining, one
As be used for large scale aperture and process, but be rarely applied to the cone seal hole machined of small size.
The content of the invention
The purpose of the present invention is:Offer one kind is easy to process, precision is high, and five rib of taper that can be used in cone seal hole squeezes
Finishing tool.
The technical scheme is that:A kind of five rib burnishing-in knife of taper, its burnishing-in sword are 5 straight ribs, and each straight rib with
At an angle, 5 straight ribs are on the same conical surface for burnishing-in knife central axis.
5 straight rib sword sections are asymmetric pentagon.
5 straight rib swords are divided into burnishing-in sword and finishing sword according to tread degree difference.
Burnishing-in sword is three, and finishing sword is two, is symmetrical arranged, and burnishing-in sword tread degree is more than finishing sword tread degree.
5 straight swords intersect with 5 faces 10 at seamed edge be processed by shot blasting that surface roughness is not inferior to Ra0.2.
The solution have the advantages that:The present invention is finished after existing straight sword or helical edge reamer are slightly cut with scissors, five
Sword is not sharp, and support is uniform, can effectively avoid processor exert a force on hand it is uneven caused by the inclined phenomenon of hinge and hole wall axially have
Ditch phenomenon, its revised burnishing-in sword extrude smoothing, can realize the requirement of surface roughness Ra 0.8 easily on the surface of the housing,
And stable quality.
Brief description of the drawings
Fig. 1 is the front view of five rib burnishing-in knife of taper of the present invention；
Fig. 2 is the section enlarged drawing of five rib burnishing-in knife of taper of the present invention.
Embodiment
The present invention will be further described with reference to the accompanying drawings and examples：
Please refer to Fig. 1 and Fig. 2, five rib burnishing-in knife of taper of the present invention, its burnishing-in sword is 5 straight ribs, and each straight rib is equal
With burnishing-in knife central axis at an angle, certain taper is formed, to meet the technological requirement of burnishing-in processing.In addition, 5 straight ribs
On the same conical surface, i.e., the distance of 5 straight rib to axis is equal, and support effect during knife is squeezed to improve, avoids the occurrence of and cuts partially
Phenomenon.
Described 5 straight rib swords are divided into burnishing-in sword and finishing sword according to tread degree difference, wherein, burnishing-in sword is three, mainly
Burnishing-in and supporting role are played, finishing sword is two, is symmetrical arranged, for improving stock-removing efficiency.In addition, the burnishing-in tread degree is big
In finishing tread degree so that 5 straight rib sword sections are asymmetric pentagon, are repaired using asymmetrical two finishing swords, can
To effectively improve burnishing-in processing efficiency.At the same time 5 straight swords intersect with 5 faces 10 at seamed edge be processed by shot blasting that surface is thick
Rugosity is not inferior to Ra0.2, to meet requirement on machining accuracy.
In certain example by taking aluminium is processed as an example, 2 finishing tread degree are 0.1mm, no more than 0.2mm；3 burnishing-in tread degree
It is 0.2mm, no more than 0.4mm, roughness, which is not inferior to Ra0.2, first slightly to be cut with scissors using general hand reamer, and unilateral made allowance is not
More than 0.02mm, applying axial force along cutter head direction using the invention, 2 finishing swords carry out off side on hole wall
Finishing, is similar to micro-cutting, and 5 planes, which are used to hold, considers to be worth doing, and 3 burnishing-in swords further extrude hole wall, reach technological requirement.
Five rib structures form five supports in process, and support effect is more uniform, along with finishing sword has at least width of 0.1mm
Degree, it is not sharp, therefore can effectively avoid processor exert a force on hand it is uneven caused by the inclined phenomenon of hinge and hole wall axially there is ditch to show
As.
The invention machined more than 10,000 holes in actual production, have passed through sufficient verification, easy to process, hole surface
Roughness is better than Ra0.8, and stable quality.
