Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Embodiment
As shown in Fig. 1 ~ 3, a kind of process tool of air-cooled diesel engine cylinder cap is substantially a kind of single-blade boring reamer, including
Cutter positioning seat 10 and cutter hub 20, the cutter positioning seat 10 and cutter hub 20 are fixed and are corrected by locking screw, described
Cutter hub 20 is concentrically mounted in the axial direction of cutter positioning seat 10, and the cutter hub 20 includes alloy boring cutter 21 and knife bar 22, the conjunction
Golden boring cutter 21 is arranged concentrically with knife bar 22, and the knife bar 22 is equipped with only tight location hole 221 and adjustment screw hole 222, described only tight
The axial angle α of location hole 221 and knife bar 22 is 30 °, axially vertical, the adjustment of the adjustment screw hole 222 and knife bar 22
Screw hole 222 with only tight location hole 221 is vertical and is connected to.
Using locking screw fixed correction cutter positioning seat 10 and cutter hub 20, guarantee that cutter hub 20 and machine spindle are concentric
And the circular runout of cutter hub 20, it improves the concentricity of cutter and then improves the precision of cutter；The compression of the blade of the cutter is logical
It crosses on knife bar 22 and gives the adjustment that cutter hub slot rear is adapted to adjustment screw hole 222 with the fastening bolt that only tight location hole 221 cooperates
Screw is completed, and after blade clamps, blade and cutter hub form entirety, avoids insufficient clamping force and the blade that generates
Displacement；Being adjusted axially for blade is completed by adjusting screw axial after blade, after compensating blade abrasion or reface
Size is mainly guaranteed precision radially without adjustment by the blade bearing that refined and blade, and it is convenient rapidly to adjust section.Knife bar
The adjustment of 21 axial dimension of alloy boring cutter on 22 is also very easy, in the cutting edge part of boring cutter, passes through the angle of cutting edge
Matching adjusting is carried out with cylinder head guide pipe chipping allowance and the size to be gone, can entirely adjusted knife while adjustment
Journey only needs several seconds.
As shown in Figures 2 and 4, the alloy boring cutter 21 is PCBN blade, and the 21 cutter head portion of alloy boring cutter is equipped with cutting edge
211, the lower section of the cutting edge 211 is equipped with chip space 212, and the front end of the chip space 212 is equipped with reamer sword 213.
The valve line of processing valve retainer is using the whole face PCBN blade that can at least reface 20 times, with heart in knife bar 22
It is 45 degree at angle, reamer sword 213 is formed by the front end portion of chip space 212, solves welding processing forming reamer bring
Quick abrasion is not easy to reprocess, the problems such as processing cost is high, at the same reamer sword 213 cutting edge 211 is cut the revolution mark that leaves into
Row is repaired, and be ensure that the precision of conduit and the roughness of conduit, is in addition being cut in the side of cutter by the angle of cutting edge
Cut guide hole 0.40MM apart from when, the side of cutter forms cutting guiding, ensure that the concentricity of conduit.Alloy boring cutter 21 is whole
It is easy to adjust, clamping force is big, ensure that cylinder cap repeatable accuracy and reliability, avoid processing in interfering, reduce abrasion,
Improve durability.
The coolant liquid of the alloy boring cutter 21 flows to from the chip space 212 of alloy boring cutter 21 and rushes at point of a knife.Due to valve seating
The coupling part of circle and guide hole is the extremely complex air flue of shape, cold when using the conventional type of cooling from the front to the back
But the iron filings generated when liquid can be by processing rush in air flue, and the iron filings remained in air flue will seriously affect the quality and property of engine
Energy.Therefore, design is flowed to using the coolant liquid for rushing at point of a knife from chip space 212, so that iron filings are gone out into cylinder cap as much as possible,
Guarantee the cleaning of air flue, while the chip space 212 of alloy boring cutter 21 is the design of straight trough open type, is even more convenient for chip removal.Processing effect
Rate is higher.
The retaining part of the alloy boring cutter 21 and knife bar 22 is clamped using thermal expansion and contraction principle production.There is cutting to lead for it
To the features such as integrated, precision is high, circular runout is small, the high production tool speed of concentricity is fast.
