Description
Technical field
The utility model is related to the technical field that wheel detection and burr remove, specifically a kind of wheel flange height
Difference detection and annular groove deburred device.
Background technology
Wheel flange face is related to the installation of wheel, stringent control flange flatness is needed, for there is flange ring channel structures
Wheel, it is also necessary to the difference in height of stringent control flange inner ring and outer ring generally requires outer ring higher than inner ring by 0.15 ± 0.05
mm.Currently, lacking the equipment of 100% automatic detection flange difference in height in actual production, three coordinate measuring machine can only be relied on to inspect by random samples,
Efficiency is low, poor reliability, easily causes batch waste product.In addition, ring channel structures both sides circumferencial direction is tiny burr, if too late
There is the risk of very big corrosion, mostly use manually clear up at present in Shi Qingli, not only consistency and circularity are poor, deep mixed,
And it is easy to scratch flange face.This patent is based on this present situation, provides a kind of wheel flange testing for level difference and annular groove burr is clear
Device is managed, the cleaning of the testing for level difference of wheel flange inner ring and outer ring and annular groove burr has been subjected to orderly linking sum aggregate
At not only realizing 100% automatic detection, also achieve the burr of high-precision removal annular groove both sides.
Invention content
The purpose of this utility model is to provide for a kind of wheel flange testing for level difference and annular groove deburred device, energy
It is enough in automatic continuous production, not only realizes that 100% detects flange difference in height automatically, moreover it is possible to realize high-precision removal annular groove
The burr of both sides.
To achieve the goals above, the technical solution of the utility model is：A kind of wheel flange testing for level difference and annular
Slot deburred device, by rack, bottom support plate, servo motor, axis, bearing block, bearing, rotating disk, lower cylinder I, guide post, inspection
