Embodiment
For ease of understanding the present invention, spy's specific embodiment in conjunction with the accompanying drawings is illustrated, but present embodiment should not regarded any limitation of the invention as.
In conjunction with Fig. 2, Fig. 3, Fig. 4, Fig. 5; A kind of buffer type cylinder structure comprises front cover assembly 1, cylinder barrel 2, piston assembly 3, rear end cover assembly 4; Above-mentioned front cover assembly 1 is made up of dust ring 5, oil-containing guide sleeve 6, front cover 7, front cover buffer ring 8, front cover zero type circle 9, front cover washer 10, front cover tapping screw 11, front cover buffering control valve device 17; Above-mentioned rear end cover assembly 4 is made up of rear end cover 12, rear end cover buffer ring 13, rear end cover zero type circle 14, rear end cover washer 15, rear end cover tapping screw 16, rear end cover buffering control valve device 18; Piston assembly 3 is made up of piston rod 19, nut 20, left piston cushion collar 21, seal ring 22, guidance tape 23, right buffer piston cover 24, zero type circle 25, socket head screw assembly 26; Above-mentioned front cover buffering control valve device 17, rear end cover buffering control valve device 18 are made up of adjusting nut 27, metering needle 28, adjustment sleeve 29, zero type circle 30, zero type circle 31, zero type circle 32; Front cover assembly 1 is connected and fixed by front cover tapping screw 11 and cylinder barrel 2; Rear end cover tapping screw 16 is connected and fixed rear end cover assembly 4 and cylinder barrel 2; Piston assembly 3 can side-to-side movement at cylinder barrel 2 inner chambers; When the left movement, left piston cushion collar 21 contact front cover buffer rings 8 form a closed air chamber to piston assembly 3 between left piston cushion collar 21 and the front cover assembly 1 by pressure reduction; Gas in this buffer cavity can only cushion control valve device 17 by front cover and discharge.When front cover buffering control valve device 17 apertures are very little, the outside exhaust of buffer cavity seldom, piston assembly 3 continues then to be in adiabatic compression in this buffer cavity to left movement, makes the cavity pressure fast rising.This pressure produces opposition to piston assembly 3, thereby piston assembly 3 is slowed down, and until stopping, avoiding or alleviated the bump of 3 pairs of front covers 7 of piston assembly, has reached the purpose of buffering thus.The aperture of front cover buffering control valve device 17 by metering needle 28 by regulating nut 27 clockwise or be rotated counterclockwise and can change the cushioning effect ability.When piston assembly 3 moved right by pressure reduction, right buffer piston cover 24 contact rear end cover buffer rings 13 formed a closed air chamber between right buffer piston cover 24 and the rear end cover assembly 4 and claim buffer cavity.Gas in this buffer cavity can only cushion control valve device 18 by rear end cover and discharge.When rear end cover buffering control valve device 18 apertures are very little, the outside exhaust of buffer cavity seldom, piston assembly 3 continues to move right, and then is in adiabatic compression in this buffer cavity, makes the cavity pressure fast rising.This pressure produces opposition to piston assembly 3, thereby piston assembly 3 is slowed down, and until stopping, avoiding or alleviated the bump of 3 pairs of rear end covers 12 of piston assembly, has reached the purpose of buffering thus.The aperture of rear end cover buffering control valve device 18 by metering needle 28 by regulating nut 27 clockwise or be rotated counterclockwise and can change the cushioning effect ability.Cushioning effect is by regulating nut 27 clockwise or be rotated counterclockwise the aperture size that decides front cover buffering control valve device 17 and rear end cover buffering control valve device 18 by described metering needle 28.Front cover buffering control valve device 17, rear end cover buffering control valve device 18 are formed by regulating nut 27, metering needle 28, adjustment sleeve 29, zero type circle 30, zero type circle 31 and zero type circle 32.
Metering needle 28 is by regulating nut 27 clockwise or be rotated counterclockwise the aperture size that decides the buffering control valve device, and can be spacing by regulating nut 27, can not produce misoperation when regulating, and guarantees equipment and operator's personal safety.
Regulate nut 27, metering needle 28 and adjustment sleeve 29 materials and can use copper material, steel, aluminium, engineering plastics.Front cover is regulated trimmer valve device 17 and front cover 7; When rear end cover buffering control valve device 18 cooperates with rear end cover 12, increase the structure tightness of front cover assembly 1 and rear end cover assembly 4, can solve the processing of infiltrating of forward and backward end cap to cylinder, minimizing reaches and improves yield rate, cost-effective purpose the treating process of aluminium, the technology subsurface defect of zine pressure casting trachoma pore own.
