Abstract
The utility model discloses a kind of quick changing oil cylinder of bi-directional expansion, comprise cylinder barrel, piston rod, filler opening and oil outlet, it is characterized in that, described cylinder barrel, piston rod and oil outlet have two groups respectively, and be axle symmetrically structure with filler opening, described filler opening is vertically located at the midpoint of the two groups of cylinder barrels linked together, and be provided with one group of oil outlet often organizing the left surface, one end of cylinder barrel away from filler opening, right surface is respectively provided with one group of connecting base.By above setting, the cylinder barrel intensity that the utility model adopts improves, and wall thickness reduces, weight saving, and can realize bi-directional expansion, improves working efficiency, and reduces rate of fault.The utility model compact structure, takes up room little, and good airproof performance, also helps safety in production while reducing cost of production.
Description
Technical field
The utility model relates to a kind of oil cylinder, is a kind of quick changing oil cylinder of bi-directional expansion specifically.
Background technique
The method that old-fashioned flexible quick changing oil cylinder adopts, for control two kinds of actions by two quick changing oil cylinders, needs larger installing space, is unfavorable for assembling, cause changing part efficiency low, and rate of fault is higher, while increase cost of production, is also unfavorable for keeping the safety in production.
Model utility content
The purpose of this utility model is to provide the quick changing oil cylinder that a kind of compact structure, installing space are little, change the high bi-directional expansion of part efficiency.
For achieving the above object, the utility model comprises cylinder barrel, piston rod, filler opening and oil outlet, described cylinder barrel, piston rod and oil outlet have two groups respectively, and be axle symmetrically structure with filler opening, described filler opening is vertically located at the midpoint of the two groups of cylinder barrels linked together, be provided with one group of oil outlet often organizing the left surface, one end of cylinder barrel away from filler opening, right surface is respectively provided with one group of connecting base.
Described often group cylinder barrel inner hollow, one group of guide sleeve and piston is respectively provided with successively by outer and interior, be provided with one group of piston rod in the inside often organizing cylinder barrel, described piston rod successively through guide sleeve and piston, is provided with one group of bar head by outer and interior in the one end often organizing piston rod and extraneous contact.
Described two groups of guide sleeves and the cavity formed between piston and cylinder barrel are rodless cavity.
By above setting, the cylinder barrel intensity that the utility model adopts improves, and wall thickness reduces, weight saving, and can realize bi-directional expansion, improves working efficiency, and reduces rate of fault.The utility model compact structure, takes up room little, and good airproof performance, also helps safety in production while reducing cost of production.
Accompanying drawing explanation
Now by reference to the accompanying drawings the utility model is described further
Fig. 1 is the utility model structural representation.
In figure: 1, cylinder barrel, 2, piston rod, 3, filler opening, 4, oil outlet, 5, connecting base, 6, guide sleeve, 7, piston, 8, bar head, 9, rodless cavity.
Embodiment
As shown in Figure 1, the utility model comprises cylinder barrel 1, piston rod 2, filler opening 3 and oil outlet 4, described cylinder barrel 1, piston rod 2 and oil outlet 4 have two groups respectively, and be axle symmetrically structure with filler opening 3, described filler opening 3 is vertically located at the midpoint of the two groups of cylinder barrels 1 linked together, be provided with one group of oil outlet 4 often organizing the left surface, one end of cylinder barrel 1 away from filler opening 3, right surface is respectively provided with one group of connecting base 5.
Described often group cylinder barrel 1 inner hollow, one group of guide sleeve 6 and piston 7 is respectively provided with successively by outer and interior, one group of piston rod 2 is provided with in the inside often organizing cylinder barrel 1, described piston rod 2 successively through guide sleeve 6 and piston 7, is provided with one group bar head 8 in the one end often organizing piston rod 2 and extraneous contact by outer and interior.
Described two groups of guide sleeves 6 and the cavity formed between piston 7 and cylinder barrel 1 are rodless cavity 9.
By above setting, the utility model operationally, hydraulic oil enters rodless cavity 9 by hydraulic system by filler opening 3, fluid constantly inputs and promotes two groups of pistons 7 when reaching enough pressure and move, two groups of piston rods 2 constantly stretch out, until reach the parameter stroke value of setting, two groups of bar heads 8 reach capacity position, complete two actions simultaneously.When finishing the work the not used time, hydraulic oil enters cylinder rod chamber by two groups of oil outlets 4, and when entering abundant, two groups of pistons 6 that hydraulic oil promotes rod chamber make two groups of piston rods 2 bounce back, until two groups of piston rods 2 contact simultaneously.
