Document Type and Number:
Japanese Patent JPH0545105
Kind Code:
A
Abstract:
PURPOSE:To obtain a measuring apparatus of inside diameters which can measure the inside diameters of a number of identical components with high efficiency and high precision. CONSTITUTION:A flange-shaped workpiece stopper 4 is fitted on the outer circumference of a columnar plug body 2 of a plug gage (measuring apparatus of inside diameters) 1, while the plug body 2 is fixed and held by a stand 6. Only by putting a component W on the plug body 3 fixed by the stand 6, in the plug gage 1, the component W is stopped by the workpiece stopper 4 and positioned in relation to the plug body 2.
