Machine drives the vertical water surface of screw rod to move up and down to realize vertical scanning.After the completion of vertical scanning, vertical adjustment block and single shaft are unloaded
Horizontal adjustment block is fixed on scanning water tank, uniaxial screw mechanism level is fixed on horizontal adjustment block, leads to by screw mechanism
It crosses horizontal adjustment block screw rod adjustment and the water surface is horizontal, drives horizontal screw bolt horizontal movement to realize scanning head water by motor
Simple scan.But this 3 D scanning system needs to unload uniaxial screw mechanism and vertical adjustment block after the completion of vertical scanning,
Then horizontal adjustment block and uniaxial screw mechanism to be reinstalled, and readjusts level, operating procedure is relatively complicated, while by
It is fitted without reference scan probe in the scanning system, is fluctuated in test if there is dosage rate, the three-dimensional curve meeting drawn out
There is wave crest burr, influence the accuracy of measurement result, in some instances it may even be possible to cause serious consequence.
