Air cylinder special for machinery and capable of detecting inner pressure, reducing vibration and filtering dust

Abstract

The invention discloses an air cylinder special for machinery and capable of detecting inner pressure, reducing vibration and filtering dust. The air cylinder comprises an air hole and a piston rod; the air hole is formed in the upper portion of a rear cylinder cover; the position, close to the air hole, of the left side of the interior of the rear cylinder cover is provided with a vibration reduction pad; the position, close to the vibration reduction pad, of the left side of the interior of a cylinder barrel is provided with a piston, the left side of the piston is provided with a buffer ring, and the left side of the buffer ring is provided with an embedded pressure sensor; and the piston rod is installed on the left side of a front cylinder cover. The air cylinder is scientific and reasonable in structure and safe and convenient to use, the interior of the air cylinder is provided with the pressure sensor, thus, the inner pressure of the air cylinder can be detected in real time, and change of the pressure inside the air cylinder can be found in time; the cylinder barrel is internally provided with the vibration reduction pad, and thus, vibration generated when the piston makescontact with the cylinder barrel during moving can be effectively reduced; and an air filter is arranged at the air hole, so that dust in the air is effectively prevented from entering the air cylinder.

Description

technical field [0001] The invention belongs to the technical field of machining parts, and in particular relates to a machine-specific air cylinder capable of detecting internal pressure, damping shock and filtering dust. Background technique [0002] The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. Air expands in the engine cylinders to convert thermal energy into mechanical energy; gas is compressed by pistons in the compressor cylinders to increase its pressure. The housings of turbines, rotary piston engines, etc. are often also referred to as "cylinders". The application fields of the cylinder: printing (tension control), semiconductor (spot welding machine, chip grinding), automation control, robot and so on. The thrust and pull forces on the piston rod are determined according to the force required for the work. Therefore, when selecting the cylinder, the output force of the cylinder should hav...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a machine-specific cylinder with detectable internal pressure, shock absorption and dust filter, so as to solve the problem that the cylinder proposed in the above background technology cannot measure the pressure during use, and cannot measure the pressure when the cylinder leaks. It was discovered in time that the piston inside the cylinder was vibrated due to the back and forth movement when it moved up and down, and there was no dust removal device at the air hole of the cylinder, which caused the dust inside the cylinder to enter the cylinder when the gas was inhaled, affecting the service life of the cylinder.
