Description
Technical field
The present invention relates to automobile engine rolling crankshafts processing technique field, specifically a kind of fillet rolling bent axle is heavy to be cut
Groove depth detection means and detection method.
Background technology
In automobile engine, bent axle is subject to the maximum part of load, when engine works, each several part meeting of bent axle
By bending, reverse, the power such as tension and compression and shearing is acted on.Motion state of the bent axle often in rotation at a high speed, it is desirable to foot
Enough wearabilities and intensity, to improve the wearability and endurance life of bent axle, journal surface and fillet are needed by reinforcing
Reason, to reach higher case hardness and surface roughness.Cast currently in order to reducing many commercial car bent axles of cost using spheroidal graphite
Iron replaces alloy steel crank shaft, and spheroidal graphite cast-iron is generally using the round as a ball reinforcing of fillet and journal surface quenching technical.Finish rolling hardening is universal
Rolling mode is cut using fillet is heavy：Sink to cut out exactly at axle journal knuckle and rolled with roller radius size identical fillet
Pressure.The processing technology of bent axle：Smart car axle journal is cylindrical and the whole main shafts of undercut groove → axle journal mid frequency induction hardening → fillet rolling → fine grinding,
Connecting rod is cylindrical and thrust surface.During grinding, in addition to needing to be ground except thrust shelves side, other main shafts and rod journal are only ground axle
Footpath, no longer grinding side, can greatly improve production efficiency.
Undercut groove depth dimensions how is fast and effectively controlled to seem particularly heavy in crankshaft journal undercut groove process
Will, because undercut groove is too deep, crankshaft structure intensity can be reduced, and cut groove fillet excessively shallow；Because bent axle can be deformed after rolling, bounce can become
Greatly, partial reinforment layer can be ground off in grinding, reduces the fatigue strength of bent axle.And relatively effective detection means exists at present
Detected on platform, it is necessary to bent axle is placed on platform, crankshaft axis put down with platform with the vernier height gauge with dial gauge
Row is tied in face, dial indicator measuring head be placed on tested crankshaft journal it is cylindrical on, by along gently being moved perpendicular to centerline direction
Dial gauge, finds cylindrical Up Highway UHW peak and presses 1-2mm to zero on pointer, dial indicator measuring head is then moved to undercut groove bottom
Portion, is moved respectively to parallel to axial direction and perpendicular to axial direction, finds undercut groove bottom minimum point, is read on dial gauge
Numerical difference, the numerical value is exactly the depth value of undercut groove, and this method is numerous and diverse, time-consuming, it is impossible to realize on-line checking.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, and provide a kind of fillet rolling bent axle undercut groove depth inspection
Device and detection method are surveyed, the apparatus structure is simple, and measurement error is small, and precision is high, quickly can effectively realize that on-line checking is heavy and cut
Groove depth, the detection method is simple to operate.
Realizing the technical scheme of the object of the invention is：
A kind of fillet rolling bent axle undercut groove depth detection apparatus, including gauge stand and dial gauge, dial gauge are fixed on gauge stand, table
Seat bottom surface be placed in measured axis undercut groove axle journal it is cylindrical on, a measurement bar, institute are extended in the lower end of the dial gauge straight down
State the surface that measurement bar is located at measured axis undercut groove axle journal.
Described gauge stand bottom surface is provided with groove, and groove blocks the axle journal of measured axis undercut groove axle.
Described groove is V-groove, and the subtended angle of V-groove is 120 °.
Using the method for above-mentioned fillet rolling bent axle undercut groove depth detection apparatus, following steps are specifically included：
1）By detection means frame on the axle journal where undercut groove to be measured, it is cylindrical that the measurement bar of dial gauge lower end is also placed in axle journal
Bus on, by percentage gauge pressure 1-2mm return to zero；
2）Detection means is moved in the axial direction, dial gauge measurement bar is extended in undercut groove, and moves back and forth detection dress vertically
Put, until measurement bar finds the minimum point of undercut groove, and the value that takes reading, then this reading is then the actual grade of undercut groove.
Beneficial effect：The apparatus structure is simple, and the groove of device gauge stand bottom surface uses the self centering principle of V-groove, and
Can only be moved along the line of centres, in the cylindrical any position of axle journal, be quickly found out the plane of axial line, and find axle journal it is cylindrical on
Bus peak, this point and the line of centres are axle journal radius, and in undercut groove bottom by being axially moveable, it is heavy accurately to find out
The minimum point of groove, fast and accurately detects deep gouge depth value, solves and detects cumbersome, efficiency is low, it is impossible to on-line checking, it is impossible to
The problem of defect can not being found in time；Due to not using platform and height gauge, but by the direct reading of dial gauge, therefore it can arrange
The problem of being varied with each individual except testing result；The detection method is simple to operate, and measurement accuracy is higher, and realizes online and quick
Testing goal.
