[0002] A hydraulic axis device is a mechanical device that operates using the hydraulic principle. It usually contains one or more hydraulic cylinders, which are equipped with pistons. The pistons are driven to reciprocate in the cylinders by the pressure of the liquid. The hydraulic axis device uses liquid (usually hydraulic oil) as the working medium, and the liquid is transported to the hydraulic cylinder by a hydraulic pump to achieve the drive and control of the axis. Hydraulic axis devices are widely used in various industrial equipment and machinery, such as construction machinery, metallurgical equipment, ships, aircraft, machine tools, etc. They are often used to achieve various actions, such as lifting, pushing, clamping, rotating, etc.
