Gas-type inner diameter measuring tool for equal-diameter deep hole detection

The invention discloses a gas-type inner diameter measuring tool for equal-diameter deep hole detection. The tool comprises a parallel type positioning and clamping mechanism, an adaptive measuring and display mechanism, a measuring position adjustment mechanism and a system controller; the system controller controls the parallel type positioning and clamping mechanism and realizes automatic positioning and clamping between the full-automatic inner diameter measuring tool and a workpiece to be measured; under the support of the parallel type positioning and clamping mechanism, the system controller controls the measuring position adjustment mechanism to drive the adaptive measuring and display mechanism to the to-be-measured position of the inner diameter of the equal-diameter deep hole ofthe workpiece to be measured; and the adaptive measuring and display mechanism completes the inner diameter measurement and display of the to-be-measured position of the equal-diameter deep hole of the workpiece to be measur
