Description
Technical field
This utility model relates to the process tool technical field of engine cylinder cover, particularly relate to a kind of cylinder cap camshaft hole and
The cutter of oil sealing hole processing.
Background technology
Prior art when polish cylinder cap camshaft hole and oil sealing hole, typically has two ways on horizontal Machining centers,
First kind of way is that camshaft hole is processed respectively with oil sealing hole, i.e. process tool completely separable (such as Fig. 1 and 2)；The second way
It is that oil sealing hole finishing tool is combined with camshaft hole bullport finishing tool.Camshaft hole totally five grades, middle three gears are right
The first axis coaxle degree formed with fifth speed requires as Φ 0.025, and camshaft hole first and fifth speed are formed by oil sealing hole
Axis coaxle degree requires to be Φ 0.025, and in prior art, first kind of way is difficult to ensure that required precision and replacing cutter take and add
Work beat, second way process capability in batch production can not meet requirement (such as the single dege blade of Fig. 3), need to strengthen detection
The frequency carries out condition monitoring process.
Summary of the invention
For overcoming above-mentioned shortcoming of the prior art, this utility model provides a kind of cylinder cap camshaft hole and oil sealing hole finishing
Work cutter, uses same cutter camshaft hole polish to be processed at one time with oil sealing hole polish, it is ensured that camshaft
The requirement on machining accuracy in hole and the requirement on machining accuracy of oil sealing hole, the course of processing is controlled, does not i.e. increase cutter changing number of times and drops again
The low frequency afterwards inspected by random samples, improves production efficiency.
To achieve these goals, this utility model takes following technical scheme: a kind of cylinder cap camshaft hole and oil sealing
Hole finishing tool, including polish single dege blade, supports sliver, cutter hub, oil sealing hole polish blade, adpting flange and cutter
Handle, described handle of a knife is fixedly linked with oil sealing hole polish blade by adpting flange, and oil sealing hole polish blade is connected with cutter hub,
It is characterized in that: also include semifinishing quadrangle blade, cutter hub termination is sequentially provided with polish single dege blade and half finishing
Work quadrangle blade.
Described semifinishing quadrangle blade includes two tetragonal blades, and quadrangle blade is all by housing screw and cutter
Body connects.
Described polish single dege blade is connected with cutter hub by screw.
Described support sliver is 4 and is distributed in cutter hub circumference.
Described semifinishing quadrangle blade, polish single dege blade and support sliver are PCD material.
Compared with prior art, this utility model has the advantages that relatively conventional cutter, camshaft hole half finishing
Work blade is by single dege blade more for quadrangle blade, and quadrangle blade four angles in the course of the work all can use, when first
Blade pressing screw can be unclamped after the cutting edge abrasion at individual angle, the cutting edge that blade 90-degree rotation changes another angle is made
With, the rest may be inferred, the blade the most more renewed after the cutting edge at four angles all weares and teares, and compares the single-blade semifinishing of conventional knife
Blade (just need to more renew blade) after abrasion, improves the service life of blade；This cutter is by semifinishing quadrangle blade, essence
Processing single dege blade, oil sealing hole polish blade are combined, because oil sealing hole is disposably processed with camshaft hole, it is to avoid because of cutter more
The resetting error changed and introduce, cutter is combined front cam axis hole and oil sealing hole axiality process capability CPK≤1.0, uses
Camshaft hole and oil sealing hole axiality process capability CPK >=1.33 after compound tool.Camshaft hole and oil sealing hole finishing tool
Being complex as together, camshaft hole disposably processes with oil sealing hole, is more conducive to ensure the axiality in hole.This cutter is overall
Hard alloy sliver formula Single-blade reamer, uses PCD blade and PCD to support sliver, it is achieved camshaft hole partly finish reams, essence school and oil sealing
Essence school, hole, oil sealing hole is compound with camshaft hole process tool, i.e. improves working (machining) efficiency, in turn ensure that machining accuracy.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further.
As Figure 4 and 5, cylinder cap camshaft hole and oil sealing hole finishing tool include polish single dege blade 2, support sliver 3,
Cutter hub 4, oil sealing hole polish blade 5, adpting flange 6 and handle of a knife 7, described handle of a knife 7 is by adpting flange 6 and oil sealing hole polish
Blade 5 is fixedly linked, and oil sealing hole polish blade 5 is connected with cutter hub 4, and it also includes semifinishing quadrangle blade 1, cutter hub 4
Polish single dege blade 2 and semifinishing quadrangle blade 1 it is sequentially provided with on termination；Polish single dege blade 2 by screw with
Cutter hub connects；Support sliver 3 is 4 and is distributed in cutter hub circumference.
Described semifinishing quadrangle blade 1 includes two tetragonal blades, and quadrangle blade is all by housing screw 1 '
It is connected with cutter hub；Semifinishing quadrangle blade 1, polish single dege blade 2 and support sliver 3 are PCD material.
Such as Fig. 6, add man-hour, Φ 48 oil sealing hole side feed from Fig. 6, with No. I camshaft hole for guiding, process No. II hole,
Then with I, No. II hole for guiding, process No. III hole, carry out camshaft hole semifinishing, polish by that analogy, finally add
No. V camshaft hole of work oil sealing hole blade simultaneously starts processing oil sealing of hole until being machined to the depth dimensions required by technique.Oil
The monolateral 0.15mm allowance that stays of sealing of hole, after camshaft hole semifinishing, sky is monolateral stays allowance 0.15mm, cutting speed
260m/min, often rotates into 0.08mm.
Cutter of the present utility model is by semifinishing quadrangle blade 1, polish single dege blade 2, oil sealing hole polish cutter
Sheet 5 is combined, because oil sealing hole is disposably processed with camshaft hole, it is to avoid the resetting error introduced because of cutter changing, cutter
The compound front cam axis hole of tool and oil sealing hole axiality process capability CPK≤1.0, use camshaft hole and oil sealing hole after compound tool
Axiality process capability CPK >=1.33.
The foregoing is only one of embodiment of the present utility model, application is relatively strong, and may extend to other has similar processing
Apply on the cutter required.
