PURPOSE: A 3D measuring device of a block is provided to reduce the number of processes for measuring a large block, to enhance the stability of a work, and to prevent economic loss by protecting an expensive sensor from impact. CONSTITUTION: A 3D measuring device of a block comprises a rotation supporting bracket(241), a locking bracket(242), a protective cover(250), an operating shaft(262), an operating member(263), a spacer, a plurality of buffering members(270), and an insulating member. The rotation supporting bracket is fixed to both upper sides of a frame(200). A latching groove(242a) is formed in the locking bracket. The protective cover is formed of an upper plate(251) and a lateral plate(252) of the size capable of covering a first sensor(210) and second sensors(220a,220b,220c,220d). The operating shaft is penetrated to be installed in the lateral plate of the protective cover which faces the locking bracket to be rotatable. A screw unit(262a) is formed in one side of the operating shaft and coupled with a nut(262b). The operating member is installed to be rotatable around the operating shaft. The spacer maintains a gap between the operating member and the lateral plate. |
