Description
Technical field
The invention belongs to engine crankshaft manufacture fields, and in particular to remove flash removed for crankshaft intersection oilhole to a kind of
Cutter and its application method.
Background technique
Crankshaft is one of engine core part, and the oil delivery holding by oilhole in crankshaft is true to the lubrication of crankshaft
Protect the important method of crankshaft reliably working.If the burr removal generated in oilhole in crankshaft manufacturing process is not clean, can very
Bearing score influences service life of aeroengine when being easy to cause engine operation.It is general to the burr generated in metal product process
It is to carry out burr removal using its roughened surface, file head working face generallys use plating high rigidity metal mill using file head
Material, or open up the modes such as blade slot and carry out surface roughening treatment.However the different trends inside Crankshaft Machining field, crankshaft
Oilhole intersection situation it is very universal, due to crankshaft oil hole is generally all more elongated and intersection formed burr it is quite multiple
It is miscellaneous；The burr removal of the portion faces mainly takes two ways: one is mechanical and electrolytic formulas, using electrolysis installation in two-phase
It hands over oilhole to be inserted into positive and negative electrode respectively, carries out electrolysis in oil duct intersection and remove flash removed.Another kind is manual formula, and use is portable
Drill point holds parallel shank twist drill and carries out up and down reciprocatingly leading to brill deburring to oilhole.Electrolytic deburring needs to put at present not yet
Universal electrolysis installation is at high cost, and processing beat is fast unlike manual straight shank twist drill deburring mode；Furthermore electrolysis mode meeting
Material and surface quality to crankshaft oil hole intersecting area generate changing and are easy corrosion, influence the crankshaft service life, client is generally not
It can agree to use.And the mode of the manual straight shank twist drill oil-through-hole deburring most generally used, as shown in figure 3, logical in drill bit
When brill, the burr of oilhole intersection can turn back into another oil duct, since drill bit is can not touching mutually with one voice for staight shank rigidity
Place's flanging burr just can not be removed directly, it is necessary to be changed direction and be bored from another oilhole is logical, but the burr of intersection can turn back back again
Originally in oil duct, logical bore again and again can only be carried out from two oilholes and guarantee that burr fractures in logical brill back and forth；Removal effect
Difference, low efficiency.The prior art is directed to the special deburring tool of intersection oilhole in crankshaft not yet.
Summary of the invention
The purpose of the present invention is provide a kind of for song for the deficiency for intersecting oilhole deburring technology in current crankshaft
Axis intersection oilhole removes the cutter and its application method of flash removed.
Realize that the technical solution of the object of the invention is as follows:
A kind of cutter removing flash removed for crankshaft intersection oilhole, unlike the prior art, including cylindrical knife bar
With the cutter head for being set to knife bar one end,
The cutter head is made of cylinder cutter hub and inner sunken face cutter hub, and the axis of cylinder cutter hub is overlapped with the axis of knife bar, cylinder
Cutter hub radius is greater than knife bar radius, and the cylinder of cylinder cutter hub is work cylinder, and inner sunken face cutter hub is held by two end faces and two
Working curved surface between face encloses, one end connecting cylinder cutter hub of inner sunken face cutter hub, and the other end connects knife bar, the work
As curved surface be one using circular arc as bus, rotated by axis of knife bar axis made of indent surface of revolution, the radius etc. of the circular arc
In the difference of cylinder cutter hub and the radius of knife bar, the circular arc and the bus on knife bar cylindrical surface are tangent in knife bar end, the work
The successively round and smooth connection of cylinder, working curved surface, knife bar cylindrical surface, the work cylinder and working curved surface carry out at roughened surface
Reason, the cutter head is subject in the upward length of cutter spindle does not interfere the working curved surface to play a role.
Further, oilhole radius 0.05-0.15mm when the radius of the work cylinder is less than work.
Further, the half of of length no more than cutter head of the work cylinder on axial rotary.
Further, the radius of the work cylinder is greater than knife bar radius 1-4mm.
Further, the cutter integrated molding is made.
The application method of the above-mentioned cutter that flash removed is removed for crankshaft intersection oilhole, unlike the prior art, including
Following steps:
S1. one end of the knife bar of the cutter is clamped using rotating machinery, cutter head protrudes into oilhole, presses spin button, utilizes
The burr of the work cylinder removal oilhole inner wall of cutter head；
When S2. needing to remove oilhole intersection area burr, turnery is carried out to oilhole corner using working curved surface and along rotary shaft
To moving repeatedly cutter head to remove flash removed.
Further, rotating machinery described in S1 is electric hand drill, compressed air drill or numerical control oilhole special plane.
Further, the rotation speed of the cutter is 450-1000r/min.
The characteristics of cutter of the technical program intersects oilhole road according to crankshaft, the work of indent was equipped in traditional cylindricality cutter head
Make curved surface, when cutter extend into oilhole intersection, the part of the working curved surface of cutter head can fall into the side of another oilhole, easily
Flanging burr at removal intersection oilhole mouth, this is that existing parallel shank twist drill can not be accomplished, is improved using the cutter
Burr efficiency has many advantages, such as simple, at low cost, the easy popularization of production.

Cylinder and working curved surface carry out coarse surface treatment, and the cutter head 1 is in the upward length of cutter spindle not interfere the work
Subject to playing a role as curved surface,
Oilhole radius 0.05-0.15mm when the radius of cylinder cutter hub 103 is less than work, the work cylinder and oil of cylinder cutter hub 103
Will lead to cutter head 1 when the excessive work in gap between hole and shaken in oilhole excessive, be easy to damage oilhole inner wall, work cylinder with
The too small cutter head 1 that will be unfavorable in gap between oilhole moves axially in oilhole,
The length of cylinder cutter hub 103 in the axial direction accounts for the half of entire cutter head 1, cylinder cutter hub 103 and inner sunken face cutter hub
101 length reasonable distribution in the axial direction is conducive to improve cutter working efficiency,
The radius of cylinder cutter hub 103 is greater than 2 radius 1-4mm of knife bar,
Cutter integrated molding is made, and advantageously reduces cutter making cost.
The application method of the above-mentioned cutter that flash removed is removed for crankshaft intersection oilhole, includes the following steps:
S1. one end of the knife bar 2 of the cutter is clamped using rotating machinery, cutter head 1 protrudes into the oilhole of crankshaft 3, utilizes cutter head
The work cylinder turnery of 1 cylinder cutter hub 103 simultaneously moves repeatedly the burr that cutter head 1 removes oilhole inner wall along axial rotary；
S2. referring to Fig. 2, when needing to remove oilhole intersection area burr, using cutter head 1 working curved surface to oilhole corner into
Row turnery simultaneously moves repeatedly cutter head along axial rotary to remove flash removed 4,
Rotating machinery described in S1 is electric hand drill,
The rotation speed of cutter is 450-1000r/min.
