Description

O-ring semi-automatic assembly machine

technical field

The utility model relates to the field of O-ring installation devices, in particular to an O-ring semi-automatic assembly machine.

Background technique

O-ring, that is, O-ring, is a rubber sealing ring with a circular cross section. Because of its O-shaped cross-section, it is called O-ring rubber sealing ring, also called O-ring. It began to appear in the middle of the 19th century, when it was used as a sealing element for steam engine cylinders. O-rings are the most common mechanical design for seals because they are inexpensive, simple to manufacture, reliable in function, and have simple installation requirements.

O-ring seals are suitable for installation on various mechanical equipment, and play a sealing role in static or moving states under specified temperature, pressure, and different liquid and gas media. It can also be used in dynamic applications where there is relative motion between components, such as the shaft of a rotary pump and the piston of a hydraulic cylinder.
