Description

Technical Field

[0001] The utility model relates to the field of actuator production equipment, in particular to an actuator pressing machine. Background Art

[0002] The working principle of the actuator is based on Pascal's law, that is, the pressure of the liquid in a closed container is evenly distributed. When the liquid is pressed into the cylinder of the actuator, the liquid will exert pressure on the piston, thereby pushing the piston forward or backward. In order to achieve this function, the piston needs to be accurately placed in the cylinder and ensure that it can move smoothly in the cylinder without leakage. During the assembly process, special tools or equipment (such as a press) are usually used to press the piston into the cylinder. When the piston is pressed into the cylinder of the actuator, the piston surface usually needs to be cleaned and sprayed with an appropriate amount of lubricant. This process is usually performed manually. There may be some impurities or corrosive agents in the piston. Manual handling poses a safety hazard and is less efficient. Utility Model Content
