Abstract

The utility model relates to a three coordinate measurer, comprising a base, a work table and a probe. Wherein, the worktable is divided into upper and lower parts. A high precision straight track pair is adopted respectively to connect the lower part of the worktable and the base, the upper part and lower part of the worktable, as well as the probe and probe seat, which allows the lower part of the worktable moving at X axis, the upper part of the worktable moving at Y axis relative to the lower part of the worktable, and the probe moving at Z axis relative to the probe base. The structure is greatly simplified due to the replacement of pneumatic guide rail in existing three coordinate measurer with high precision straight track pair between the lower part of the worktable and the base, between the upper part and lower part of the worktable, as well as between the probe and probe seat, which correspondingly reduces the producing cost and the price. Besides, an ordinary surveyor can operate successfully due to the simplification through arrangement of PCL control of the touching screen.
