Description
Technical field
The present invention relates to wheel hubs to produce detection technique field, detects more particularly, to a kind of wheel hub blank mounting surface deflection
Device.
Background technique
Personal Transporter of the automobile as current generation first choice, auto manufacturing also have become Chinese pillar industry it
One.Building block one of of the wheel as automobile most critical, and accounting is biggish is aluminium alloy wheel hub in wheel at this stage.
In the production of aluminium alloy wheel hub, Bi Ranhui is since mold is nonstandard, forging type, blank thermal deformation, heat treatment
Etc. factors influence, wheel hub blank descended the true form of production line to be bound to relative to theoretical value there is a certain error, this
Kind error is known as blank deformation.Rim faces are as mach positioning datum, if its plane deformation amount is overproof, may cause outer
It is overproof less than, dynamic balancing to take turns the inclined vehicle in edge, the processing of interior outer rim.The central axial centre for referring to wheel hub that deforms is apart from wheel rim
The distance in face and the difference of theoretical value.Hub centre is clevis and cap seam allowance Working position, and central axial deformation is overproof to be will lead to
Deduction cap mouth depth equidimension is overproof, directly results in wheel hub and scraps.Therefore, the deflection detection of casting hub blank is very heavy
It wants, tells the overproof blank of deflection, allow it not enter subsequent machining has effects that save the cost in production.
Existing wheel hub deflection detection is broadly divided into contact type measurement and non-contact measurement at present.Contact is divided into people
Work measurement and online mechanical measurement；Manual measurement measures rim faces plane deformation usually using surface ga(u)ge and clearance gauge, wherein also wrapping
Include the measurement exclusively for detection wheel hub deflection special measuring scale and other measurers.But manual measurement often participates in artificially
Manual errors and the error of measurer itself there is deviation so as to cause result accuracy.In addition, manual measurement does not simply fail to protect
The consistency for demonstrate,proving measurement accuracy, is also consumed by a large amount of human time's cost, various disadvantages is manifested in the mass production of wheel hub
End.On-line measurement may be implemented in online mechanical measurement, using the different location of touch sensor measurement hub surface, realizes hair
Base deformation monitoring.Although this contact measurement method precision is high, due to wheel hub deformation, mechanical contact is surveyed
Amount easilys lead to pop one's head in firmly in measurement process leaves measurement trace on blank, damages wheel hub.Contact type measurement point is few simultaneously,
Time of measuring is long, and can only realize the measurement of single axial deformation, is difficult to adapt to the detection of various wheel-type wheel hubs.
Non-cpntact measurement is mainly measured using laser sensor.Laser measurement is because its is non-contact, in high precision and square
Just the characteristics of realizing automatic high-efficiency measurement is more and more applied in the various measurements in production.It is surveyed in wheel hub blank
Amount aspect, laser on-line measurement application is mature, and the equipment for having applied to wheel hub deformation monitoring is swashed using point
The mode of ligh-ranging measures.But the points on the wheel hub surface that can acquire of dot laser are few, for more complicated wheel
Hub tends not to characterize blank rim faces well, so that measurement result and actual value have certain uncertainty.
