Abstract:
1. A laser calibration device comprising: a housing; a pendulum pivotally coupled to said housing and suspending downwards therefrom; a laser deck mounted to said pendulum; at least one laser for emitting a laser line, said laser pivotally mounted to said laser deck and having a laser barrel rotatable within a barrel holder and a laser lens pivotally coupled to said laser barrel; a first adjustment mechanism mounted between said laser deck and said laser for pivoting said laser with respect to said laser deck to adjust a pitch of said laser line; a second adjustment mechanism mounted between said barrel holder and said laser barrel to rotate said laser barrel with respect to said barrel holder to adjust a roll of said laser line; a third adjustment mechanism mounted between said laser barrel and said laser lens to pivot said laser lens with respect to said laser barrel to adjust a crowning of said laser line; and a fourth adjustment mechanism mounted to said pendulum for adjusting a center of gravity of said pendulum; wherein said first, second, third, and fourth adjustment mechanisms are used to make horizontal said laser line emitted from said laser.
