Sealing ring and the deficiency for damaging inner wall of cylinder, the present invention provide a kind of design rationally, sealing ring is time saving and energy saving for replacement, production cost
Low, the magnet ring not cracky and damaged fragment that formed is not easily accessible the pneumatic cylinder piston component in cylinder barrel.
The technical solution adopted by the present invention to solve the technical problems is: a kind of pneumatic cylinder piston component comprising one is living
Stopper rod, a magnet ring, two nylon chucks and two O-ring seals are equipped with the shaft shoulder, in the Buddhist nun on one end of the piston rod
Mounting hole is coaxially offered respectively on imperial chuck, it is characterised in that: is coaxially opened on the wherein side sagittal plane of a nylon chuck
Accommodation groove equipped with an annular, the magnet ring are assemblied in accommodation groove；The nylon platen is set with by mounting hole respectively
On the piston rod, a nut is threadedly coupled on the piston rod, the nut and the shaft shoulder cooperate the nylon
Chuck compression fit, and wherein the side sagittal plane of side sagittal plane and another nylon chuck where the magnet ring of a nylon chuck seals
Connection；Open up seal groove respectively on the circumferential surface of the nylon chuck, the O-ring seal is respectively assembled at corresponding
In seal groove.
Preferably, the sagittal plane on the inside of the wherein magnet ring of a nylon chuck opens up fluted, in another nylon chuck
Side sagittal plane is provided with boss, and the boss matches and is tightly connected with the groove.
Preferably, the outer diameter of the boss, the internal diameter of groove are equal with the internal diameter of the magnet ring.
Two nylon chucks suit of the invention on the piston rod, and is cooperated with the shaft shoulder by nut and compresses nylon chuck
Cooperation, magnet ring assemble in the wherein accommodation groove of the side sagittal plane of a nylon platen, and side where the magnet ring of the nylon chuck
The side sagittal plane of sagittal plane and another nylon chuck is tightly connected, the sense of magnet ring and the magnetic sensor being arranged on the outside of cylinder barrel
Sensitivity is answered to be unaffected, when impact causes magnet ring breakage, the fragment that magnet ring is formed is stored in accommodation groove, will not
Into cylinder barrel, the destruction to sealing ring, inner wall of cylinder is avoided.O-ring seal respectively corresponds the circumferential surface for being assemblied in nylon chuck
On seal groove in, using O-ring seal substitute dust-proof seal ring, which reduce production cost, the time saving province of replacement o sealing ring
Power.Nylon chuck uses nylon material, and after O-ring seal abrasion, contacting and rubbing with cylinder barrel will not be destroyed in cylinder barrel
Wall, design are reasonable.
