The utility model provides a general tool for measuring the height of a spherical surface of a piston, two ends of the piston are respectively provided with a first groove and a second groove, and the bottom of the second groove is a spherical groove. The universal jig comprises a base, a limiting step which is arranged on the base and is used for positioning a piston, and a detection pin which is in sliding connection with the base and is positioned above the limiting step, the detection pin comprises a sliding part which slides on the base, and an abutting part which is arranged below the sliding part and is used for abutting against the inner side of the spherical groove. According to the universal jig, the abutting part which can abut against the spherical groove is arranged, whether the spherical height of the piston is qualified or not can be detected by matching with the base, the problem that the distance between the piston counter bore plane and the ball head face is difficult to measure is solved, t
