End face gap online detection system

The utility model relates to an end face gap on-line detection system. The system comprises an X-Y direction execution mechanism, a Z direction execution mechanism and a displacement sensor (12). TheX-Y direction executing mechanism comprises an X direction executing module (6) and a Y direction executing module (7); the Z-direction actuating mechanism comprises a Z-direction actuating cylinder (9) and a cylinder mounting plate (10); a sliding plate (11) is connected to a push rod of the Z-direction execution air cylinder (9), the sliding plate (11) is arranged on a Z-direction guide rail (13), and the Z-direction guide rail (13) is installed on the air cylinder installation plate (10) and is perpendicular to the limiting plate (16); and a displacement sensor (12) is arranged on the sliding plate (11), so that the displacement sensor (12) moves up and down on the Z-direction guide rail (13) under the push-pull action of the Z-direction execution air cylinder (9), and online detectionis completed.
