ATOS Hydraulic Cylinder Machining As a key component of hydraulic cylinders, mining single-pillar supports, hydraulic supports, and gun barrels, the quality of the cylinder's machining directly affects the lifespan and reliability of the entire product. Cylinder machining requires high precision; the inner surface roughness must be Ra 0.4～0.8µm, with strict requirements for coaxiality and wear resistance. A fundamental characteristic of cylinders is deep-hole machining, which has always been a challenge for machining personnel. Roller burnishing, by leaving residual compressive stress on the surface layer, helps to close micro-cracks and hinders the propagation of corrosion. This improves surface corrosion resistance and delays the initiation or propagation of fatigue cracks, thus increasing the cylinder's fatigue strength. Through roller burnishing, a work-hardened layer is formed on the surface, reducing the elastic and plastic deformation of the grinding pair contact surface, thereby improving the wear resistance of the cylinder's inner wall and preventing burns caused by grinding. After rolling, the reduced surface roughness improves the fit.

ATOS cylinders, or hydraulic cylinders, are linear motion actuators whose output force is proportional to the effective area of ​​the piston and the pressure difference across it. Their function is to convert hydraulic energy into mechanical energy. The input to a hydraulic cylinder is the flow rate and pressure of the fluid; the output is linear motion speed and force. The piston of a hydraulic cylinder can perform linear reciprocating motion, but the output linear displacement is finite. A hydraulic cylinder is an energy conversion device that converts hydraulic energy into reciprocating linear motion mechanical energy. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, a piston and piston rod, sealing devices, cushioning devices, and venting devices. The cushioning and venting devices depend on the specific application; the other devices are optional.

Before installing an ATOS cylinder, preparations should be made. First, the hydraulic circuit should be depressurized; otherwise, when the oil pipe joint connected to the cylinder is loosened, the high-pressure oil in the circuit will quickly spray out. When depressurizing the hydraulic circuit, first loosen the handwheel or adjusting screw of the relief valve to unload the pressurized oil, then disconnect the power supply or power source to stop the hydraulic device from operating.

Next, begin disassembling the hydraulic cylinder.

First, to prevent bending or deformation of slender parts such as the piston rod, use wooden blocks for even support when placing the cylinder. During disassembly, avoid damaging the piston rod tip threads, oil port threads, piston rod surface, and cylinder liner inner wall.

Second, disassembly should be performed in sequence. Since the structure and size of various hydraulic cylinders differ, the disassembly sequence may vary slightly. Generally, drain the oil from both chambers of the cylinder, then remove the cylinder head, and finally disassemble the piston and piston rod. When disassembling the cylinder head, use a special tool for internal key-type connections (keys or rings); do not use a flat chisel. For flange-type end caps, use screws to push them out; do not hammer or pry. If the piston and piston rod are difficult to remove, do not force them out; first determine the cause before proceeding with disassembly.

Third, before and after disassembly, efforts should be made to prevent the hydraulic cylinder parts from being contaminated by surrounding dust and impurities. For example, disassembly should be carried out in a clean environment; after disassembly, all parts should be covered with plastic sheeting, not cotton cloth or other work cloths.

Fourth, after disassembling the cylinder, it should be carefully inspected to determine which parts can continue to be used, which parts can be repaired and reused, and which parts must be replaced.

Fifth, all parts must be thoroughly cleaned before assembly.

However, it is important to pay attention to the correct installation of all sealing devices. For example, when installing O-rings, do not stretch them to the point of deformation, and do not roll them in while installing, otherwise, they may become twisted and leak oil. All disassembled O-rings and dust rings should be replaced with new ones. Similarly, when installing Y-rings and V-rings, pay attention to their installation direction to avoid leakage due to incorrect installation. For Y-rings, the lip should face the pressurized oil cavity; furthermore, for YX-rings, pay attention to whether they are for shafts or holes to avoid incorrect installation. V-shaped sealing rings consist of support rings, sealing rings, and pressure rings of varying shapes. When the pressure ring presses against the sealing ring, the support ring causes the sealing ring to deform, thus achieving a sealing effect. During installation, the opening of the sealing ring should face the pressure oil chamber. When adjusting the pressure ring, it should be tightened only to prevent oil leakage, avoiding excessive tightening to prevent excessive sealing resistance.

Sixth, a special wrench should be used to tighten threaded connections, and the torque should meet standard requirements.

Seventh, after assembling the piston and piston rod, their coaxiality and straightness along their entire length must be measured to ensure they do not exceed tolerances.

Eighth, after assembly, the piston assembly should move without any sense of obstruction or uneven resistance.

Ninth, when installing the hydraulic cylinder onto the main unit, a sealing ring must be added between the inlet and outlet oil ports and tightened securely to prevent leakage.
