Fan blade software and hardware zero -bit calibrating device

The utility model relates to a fan blade software and hardware zero -bit calibrating device. Fan blade software and hardware zero -bit calibrating device, including the support cantilever, the one end that supports the cantilever is equipped with the plane laminating complex plane of orientation that is used for becoming oar dog contact surface with wheel hub, and the other end that supports the cantilever is equipped with the laser instrument, the axis of laser instrument with the plane of orientation coplane. Adopt above -mentioned technical scheme, during the use, become oar dog contact surface's plane laminating cooperation with plane of orientation and wheel hub, open the laser instrument, can launch with the coplaner laser of plane of orientation, laser that dependence was throwed and the contrast of the zero -bit scale mark of blade have been avoided relying on people's sight to counterpoint, and the counterpoint precision can rely on the manufacturing accuracy of support cantilever and the installatio
