Abstract

The utility model belongs to the technical field of measuring equipment, and relates to a pneumatic detection device for a rotor oil hole of an automobile VVT phaser. The utility model discloses a platform and a chassis, the platform and the chassis are fixed through a plurality of pillars, and five groups of waist line grooves distributed in an annular array along the center point of the chassis are arranged in the chassis. During detection, one-surface two-hole positioning is formed on the automobile VVT phaser rotor through the one-surface two-hole positioning structure, the correct position of the automobile VVT phaser rotor is ensured, the waist line groove is used for adjusting the angle and the position of the bottom plate, and the rotor oil hole detection assembly is located at the correct position and angle. The rotor oil hole detection assemblies can be located at the correct height by grinding the thickness of the heightening piece, each rotor oil hole detection assembly is independently controlled, all oil holes can be detected at the same time, and the detection period is shortened by more than 50% compared with a mechanical detection tool.
