Abstract

A double-piston-rod relative motion oil cylinder is structurally characterized in that a locating ring is fixed in the middle of an inner hole of an oil cylinder barrel, a left guide sleeve is fixed at the left end of the oil cylinder barrel, a right guide sleeve is fixed at the right end of the oil cylinder barrel, a middle port is located in the middle of the oil cylinder barrel and penetrates through the locating ring, a left port is located at the left end of the oil cylinder barrel, a right port is located at the right end of the oil cylinder barrel, a left piston rod penetrates through the left guide sleeve, a left piston is fixed at the inner end of the left piston rod, a right piston rod penetrates through the right guide sleeve, and a right piston is fixed at the inner end of the right piston rod. By the adoption of the double-piston-rod relative motion oil cylinder, one oil cylinder can drive two mechanisms to make relative motions simultaneously, structure is simplified, occupied space is reduced, and production cost is lowered.

Description

Double piston-rod relative movement oil cylinder
Affiliated technical field
The utility model relates to the hydraulic element field, especially a kind of double piston-rod relative movement oil cylinder.
Background technique
In machinery, often need utilize the hydraulic jack lead agency to do relative motion simultaneously, promptly two mechanisms simultaneously near or simultaneously away from, the general scheme that adopts is to use two oil cylinders, drives two mechanism kinematics respectively.This mode takes up room bigger, and oil hydraulic circuit is more complicated also.Therefore be necessary to develop a kind of novel oil cylinder, reach and just can drive two mechanisms with an oil cylinder and do relative motion simultaneously, with simplified structure, dwindle taking up room, the reduction manufacture cost.
Summary of the invention
The purpose of the utility model provides a kind of oil cylinder of new structure type, reaches just can drive two mechanisms with an oil cylinder and do relative motion simultaneously.
For achieving this end, the technological scheme that the utility model is taked is following: this double piston-rod relative movement oil cylinder mainly is made up of cylinder barrel, positioning ring, guide sleeve, piston rod, piston, it is characterized in that: a positioning ring is being fixed at cylinder tube endoporus middle part; The cylinder tube left end is being fixed left guide sleeve, and the cylinder tube right-hand member is being fixed right guide sleeve, and middle hydraulic fluid port is at the cylinder tube middle part; And pass positioning ring, and left oil port is at the cylinder tube left end, and right oil port is at the cylinder tube right-hand member; The left piston bar passes left guide sleeve; Left piston is fixed on left piston bar inner end, and right piston rod passes right guide sleeve, and right piston is fixed on right piston rod inner end.The positioning ring left side equates with the distance of positioning ring right side apart from right guide sleeve left side apart from the distance of left guide sleeve right side.The left piston bar is identical with the diameter of right piston rod.Left piston and right structure of piston and measure-alike.
When this double piston-rod relative movement oil cylinder used, when middle hydraulic fluid port oil-feed, when left oil port and right oil port oil return, left and right sides piston rod stretched out simultaneously; When the oil-feed simultaneously of left oil port and right oil port, during middle hydraulic fluid port oil return, left and right sides piston rod is withdrawn simultaneously.Left and right sides piston rod just can drive two mechanisms respectively and do relative motion simultaneously.
The beneficial effect of the utility model is, just can drive two mechanisms with an oil cylinder and do relative motion simultaneously, simplifies the structure, and has dwindled taking up room, and has reduced manufacture cost.
Description of drawings
Elaborate below in conjunction with the structure of accompanying drawing to the utility model:
Accompanying drawing 1 is a double piston-rod relative movement oil cylinder axial section schematic representation.
Embodiment
In the accompanying drawings, each component is respectively, cylinder tube 1, positioning ring 2, left guide sleeve 3, right guide sleeve 4, middle hydraulic fluid port 5, left oil port 6, right oil port 7, left piston bar 8, left piston 9, right piston rod 10, right piston 11.
The structure of double piston-rod relative movement oil cylinder shown in the drawings is: a positioning ring 2 is being fixed at cylinder tube 1 endoporus middle part, and cylinder tube 1 left end is being fixed left guide sleeve 3, and cylinder tube 1 right-hand member is being fixed right guide sleeve 4; Middle hydraulic fluid port 5 is at cylinder tube 1 middle part; And pass positioning ring 2, and left oil port 6 is at cylinder tube 1 left end, and right oil port 7 is at cylinder tube 1 right-hand member; Left piston bar 8 passes left guide sleeve 3; Left piston 9 is fixed on left piston bar 8 inner ends, and right piston rod 10 passes right guide sleeve 4, and right piston 11 is fixed on right piston rod 10 inner ends.Positioning ring 2 left sides equate with the distance of positioning ring 2 right sides apart from right guide sleeve 4 left sides apart from the distance of left guide sleeve 3 right sides.Left piston bar 8 is identical with the diameter of right piston rod 10.The structure of left piston 9 and right piston 11 and measure-alike.
