verticality measuring tool

The utility model provides a verticality measuring tool which comprises a detection pedestal with a horizontal upper surface, a detection support on the detection pedestal, and at least one dial gauge installed on the detection support along the vertical direction, wherein the measuring bar of the dial gauge is parallel to the upper surface of the detection pedestal, and the measuring heads of all dial gauges are on a same vertical line. A referential block close to the detection support is installed on the detection pedestal, and a positioning reference surface for positioning a workpiece is arranged at one side of the referential block. The positioning reference surface is perpendicular to the upper surface of the detection pedestal, and the measuring heads of the dial gauges and the positioning reference surface are on a same side. The verticality measuring tool is accurate in measurement, small in error and convenient and flexible for use, and overcomes the defects that a bevel protractor or a universal bevel protractor can not obtain accurate angle values, manual operation may causes error measured values, and that a three-dimensional coordinatograph is time consuming in measuring angles. The verticality measuring tool substantially improves production efficiency.
