Working principle of mini cylinder
Mini cylinderAccording to the force required for work size to determine the push and pull forces on the piston rod. Choose cylinderThere should be a slight margin for the output force of the cylinder. If the bore diameter is selected to be small, the output force will be insufficient and the cylinder will not work properly;but if the bore diameter is too large, it will not only make the equipment bulky and costly, but also increase air consumption, resulting in a waste of energy. When designing the clamp, a force-increasing mechanism should be used as much as possible to reduce the size of the cylinder.
Mini cylinderThere is an inlet on the end cover The exhaust port, some also have a buffer mechanism in the end cover. The rod side end cover is equipped with a sealing ring and a dust ring to prevent air leakage from the piston rod and external dust from mixing into the cylinder. There is a guide sleeve on the rod side end cover to improve the guiding accuracy of the cylinder, bear a small amount of lateral load on the piston rod, reduce the amount of downward bending of the piston rod when it extends, and extend the service life of the cylinder. Guide sleeves are usually made of sintered oil-containing alloy, forward-inclined copper castings. In the past, malleable iron was commonly used for end caps. Nowadays, in order to reduce weight and prevent rust, aluminum alloy die-casting is often used, and brass materials are sometimes used for micro cylinders.
The inner diameter of the cylinder represents the output force of the cylinder. The piston must reciprocate smoothly in the cylinder, and the surface roughness of the inner surface of the cylinder should reach Ra0.8um. For steel tube cylinders, the inner surface should also be plated with hard chromium to reduce frictional resistance and wear and prevent corrosion. In addition to using high-carbon steel pipes, the cylinder barrel material is also made of high-strength aluminum alloy and brass. Mini cylinder< /span>Some use stainless steel pipes. For cylinders with magnetic switches or cylinders used in corrosion-resistant environments, the cylinder barrel should be made of stainless steel, aluminum alloy or brass.
