Abstract
A measuring apparatus for automatically measuring the height, the dimensions of the inner and outer surfaces, and the shape of a cylindrically-shaped object. The measuring apparatus includes a measuring head vertically moving along a positioning guide supported by a support post integral with a measuring table, a height displacement measuring device, which comprises a laser distance meter provided on the measuring table, and an arithmetic processing unit. The measurement starts as the measuring head is raised by a weight from a measuring start position of the measuring table. The inner and outer surfaces of a tire are measured based on the measurements by an inner surface measuring device provided with three laser distance meters mounted to the measuring head and an outer surface measuring device having a laser distance meter and the displacement change measurement of the measuring head by the height displacement measuring device. Required dimensional values are calculated from the measured values, using the arithmetic processing unit.
