(1) when wheel hub is run to the device, the system above the device controls the device after receiving signal Operating;
(2) jacking wheel hub auxiliary detection device is to detection position: jacking moves 5 drive substrate 3 of rodless cylinder upwards, simultaneously The second driving unit 22, transmission mechanism and the chuck body that are fixed on substrate 3 is driven to be raised up under wheel hub to be detected together Side;
(3) clamping wheel hub: the second driving unit 22 drives the second splined shaft 422 of the second spline to move axially upwards along it Make, the addendum cone 423 positioned at 422 top of the second splined shaft drives the movement of Cam Follower 15 to make claw 11 to radial outside side To movement, and be fixed on wheelboss inner hole, which has carried out centering to wheel hub and the device, while also clamping wheel hub make its with Entire mechanism is relatively fixed, keeps the rotation of wheel hub fast and stable.
(4) rotation detection: after wheel hub positioning fixes, the first driving unit 21 can be driven chuck body 12 and carry out rotation fortune It is dynamic, so that wheel hub is reached each detection position and angle.
The wheel hub is detected auxiliary device and can be detected with precise positioning and drive hub for size and appearance, while can also be answered 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 only jacks wheel hub when needing to detect as below producing line.Since hub centre hole location difference is little, the dress It sets and is to position stationary hub by centre bore, center end face holds up wheel hub, therefore the most wheel-type being suitable 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 does not 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 it is extended from this it is obvious variation or It changes still within the protection scope of the invention.
