A kind of air measuring device integrating location and diameter detection described in the utility model, including base body, it is characterized in that: be provided with rectangular window in the centre of described base body, on base body, the position at two diagonal angles of this rectangular window close is respectively equipped with the first alignment pin and the second alignment pin, and described first alignment pin and the second alignment pin are connected with pneumatic detecting instrument respectively through road；
The middle part of described first alignment pin and bottom are provided with axial air inlet, and the top of described first alignment pin is provided with through bleeder port radially near the position at middle part, and this bleeder port communicates with described air inlet；
The middle part of described second alignment pin and bottom are provided with axial blowhole, and the top of described second alignment pin is provided with through steam vent radially near the position at middle part, and this steam vent communicates with described blowhole.
Further, described first alignment pin is straight pin, and its air inlet is lower big little shoulder hole；Described second alignment pin is many ribs pin, and its blowhole is also lower big little shoulder hole；Described air inlet is identical with the structure of blowhole.
Further, all there is chamfering the upper and lower end of described first alignment pin.
Further, the lower section of described second alignment pin is circular, and middle part and side, cross section, top are triangle for semicircle opposite side, and all there is chamfering the upper and lower end of described second alignment pin.
Position hole and the first alignment pin and the second alignment pin corresponding matching at electromotor workpiece after, start pneumatic detecting instrument, compression air each leads into the air inlet of the first alignment pin and the blowhole of the second alignment pin through the pipeline of pneumatic detecting instrument, by detecting the gap tolerance leakage between workpiece hole, location and the first alignment pin and the second alignment pin, by incoming for result displayable digital screen after contrast, draw the aperture measured value in the hole, location of electromotor workpiece.
This utility model can while workpiece positions the diameter in measurement and positioning hole, easy to detect, quick, result is reliable and stable, it is adaptable to the production process of various machining automatizatioies line production, especially car engine machine production line, reduces material cost and cost of labor expense.
