Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder production detection, in particular to a hydraulic cylinder welding shape and position tolerance detection equipment and detection method. Background technique [0002] As the executive part of the main engine, the hydraulic cylinder is usually hinged and installed through the cylinder bottom of the hydraulic cylinder and the pin holes at both ends of the earrings when installed on the main engine. After installation, the piston rod of the hydraulic cylinder moves axially, and the pin hole and the pin shaft are Rotational movement, during installation and reciprocating axial movement, the cylinder bottom, the center of the clevis pin hole and the axis of the hydraulic cylinder are perpendicular to the axis of the hydraulic cylinder, and the center of the cylinder bottom and the flat thickness of the clevis are symmetrical to the axis of the hydraulic cylinder. At the same time, there ar...
