Claims

[Scope of Claim for Utility Model Registration] A horizontally extending base frame having legs at the bottom of both ends and a guide surface on the top surface, and a frame mast standing at one end of the base frame and having a driving cylinder mounted vertically. , an internal ratchet wheel is rotated by extending and contracting the rod of the drive cylinder and vertically moving an arm of the ratchet device connected to the tip of the rod, and the ratchet device has an axis parallel to the base frame; an adapter that is attached to the inner diameter of the ratchet wheel and that fits with a tightening nut of the cylinder head or piston of the cylinder to be disassembled and reassembled; , a centering table with two rollers arranged in a V-shape that can move up and down, and a centering table that is coaxial with the ratchet device and near the other end of the base frame, and fixes the ends of the rods to be disassembled and reassembled. A fixed base having a pin hole and movable on the guide surface of the base frame operates the drive cylinder and relieves the discharge hydraulic pressure of the hydraulic pump driven by the motor for oil leakage testing of the assembled cylinder. The cylinder is comprised of a hydraulic pressure supply device which is bypassed by a valve and adjusted to a predetermined pressure, and alternately supplies the discharge hydraulic pressure of the oil pump to both ends of the cylinder via a control valve, and the cylinder is disassembled and assembled via a pin on the fixed base. Fix the cylinder end or rod end of the cylinder, fit the tightening nut of the cylinder head or piston of the cylinder to be disassembled and reassembled into the adapter, actuate the drive cylinder, rotate the ratchet device, and tighten the cylinder. 1. A cylinder disassembly and assembly device for attaching and detaching a tightening nut of a cylinder head or a piston.
