It is dynamic, wheel hub is made to reach each test position and angle.
Wheel hub detection auxiliary device can be detected, while can also answer with precise positioning and drive hub for size and appearance
For wheel hub that is offline and moving online, especially suitable for the wheel hub moved online.The device does not influence original online wheel hub
Movement as below producing line, only jacks wheel hub when needing detection.Since hub centre hole potential difference is not little, the dress
It puts and is that stationary hub is positioned by centre bore, center end face holds up wheel hub, therefore suitable for most wheel-type in producing line,
It can be arranged in the producing line of most Flexible productions.
Obviously, the above embodiments are merely examples for clarifying the description, and is not intended to limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And the obvious variation thus extended out or
Among changing still in the protection domain of the invention.
