Description
Technical field
The present invention relates to a kind of automatic tire pattern depths to measure detection method.
Background technology
Tire is the place that vehicle complete vehicle is uniquely contacted with ground, is contacted throughout the year with ground, it is natural to wear that.Not only
Also to pass through the oxidation in years by the abrasion on road surface, all threaten the safety of tire.The abrasion of tire is generally referred to as taken turns
The abrasion of tire decorative pattern, tyre tread are extremely important.Most important three big component part of tire is respectively：Tyre surface, carcass and rubber
Formula, they can difference in detailed design.Tread contour most important three acts on greatly：1, earth-grasping force is promoted；2, it drops
Low noise；3, increase drainage.In general the thickness of tread contour has to be more than 1.6 millimeters, but if you often exist
It drives on wet and slippery road surface, that is desirable to ensure that tread contour thickness is more than 3.2 millimeters.Common existing detection mode is artificial
It is detected with tread ruler, accuracy of detection is told somebody what one's real intentions are, can not be standardized, labor intensive, and detection is more inconvenient.
Invention content
It is an object of the invention to overcome above-mentioned deficiency existing in the prior art, and it is more convenient fast to provide a kind of measurement
Fast effective automatic tire pattern depth measures detection method.
Technical solution is used by the present invention solves the above problems：
A kind of automatic tire pattern depth measurement detection method, it is characterised in that：Including following operating procedure：

On, pressure wheel is artificial to stop in innermost two roller bearings on second detection device, switches to neutral gear and RELEASE PARKINGBRAKE, at this time
Car can do it is front and back automatically move, the wheel on right side is by two roller supports in left and right at this time, therefore wheel can be with the
Two detection devices realize centering setting；
(2) step 2 manually removes steel plate, and the roller bearing driving motor of second detection device, which is powered, realizes self-locking, and limitation is most interior
The roller bearing rotation of side two, then slowly moves second detection device by pedestal driving mechanism, until the left side wheels of vehicle are fallen into
Between two roller bearings of most inner side of first detection device；
(3) step 3, lifting hydraulic oil cylinder driving lifting frame rise, the left lifting roller groups of the first detection device, right lifting roller bearing
Group is respectively supported at the left and right sides of revolver, and the left lifting roller groups of second detection device, right lifting roller groups are respectively supported at
The left and right sides of right wheel, to realize the centering of wheel and corresponding detection machine；
(4) step 4 rises detection seat by lifting arm, and sliding drive mechanism drives laser ranging system to be moved forward and backward, and leads to
The middle part tread region for crossing laser fire tire subtracts laser ranging system with laser ranging system acquisition maximum distance and obtains vertically
Obtain measuring and calculating value of the minimum range as reflection tire tread depth；
(5) step 5, the work of roller bearing driving motor, two roller bearing rotations of driving most inner side, to drive corresponding tire to rotate
Certain angle, to realize that the position of measure of the change, the several measurement positions of changeableization can obtain multiple treads of a tire
Data more fully understand to obtain to have the service condition of tire；
(6) step 6, sliding equipment drive cam device left-right rotation, shoot tire side, and image data is sent
To server, judges that tire whether there is by backstage and caused tire abnormal condition by external force reason.
The tread depth data of the laser ranging system obtained on each measuring block is handled, any two tread groove
The absolute value of the difference of depth data is more than setting lock value, then is determined as inordinate wear.
This method is used for tire of the width of tire section between 145-275mm.
Compared with prior art, the present invention haing the following advantages and effect：Automatic tire pattern depth of the present invention measures inspection
Survey method avoids artificial acquisition tread data of squatting down one by one, caused by measuring speed is slow, working feature is big, efficiency is low
Problem improves the comfort level of operation, is advantageously implemented automation mechanized operation；Tread number is measured by laser ranging system first
According to acquisition data are very fast, and working efficiency and measurement accuracy are measured to ensure that；First detection device, second detection device are certainly
Dynamic and tire centering, to improve measurement accuracy, the first detection device, second detection device adjustment process, adapt to it is different away from
From vehicle wheelbase, to adapt to the tread measurement demand of different vehicle.
