Abstract
Description
(1) technical field
The utility model relates to a kind of built-in quick composite oil cylinder, is mainly used in the rapid system of hydraulic machinery.
(2) background technique
The utility model is the quick composite oil cylinder of a new generation newly developed on existing patented technology " complex liquid compressing cylinder " (patent No. the is 200320110440.X) basis of our company.
When stating composite oil cylinder in the use, though can accomplish the end in view, exist following problem: oil cylinder adopts external to install fast, exists defectives such as contour size of the unit(s) is big, hydraulic pipe line is installed trouble, installation space is restricted.Because problems such as machining accuracies, back cylinder piston rod breaks down with the fracture easily that connects of preceding cylinder piston.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of volume is littler, more convenient, the more reliable performance of processing, built-in quick composite oil cylinder that cost of production is lower.
The purpose of this utility model is achieved in that a kind of built-in quick composite oil cylinder, it is characterized in that: it comprises outer cylinder component, inner cylinder piston rod, the preceding guide sleeve of inner casing, back guide sleeve and guide sleeve pressing plate;
Described outer cylinder component comprises internal cylinder piston rod, guide sleeve and cap, outer shell guide sleeve, outer shell cylinder body and outer shell piston; Described outer shell guide sleeve places described outer shell cylinder body front end, is installed in the outer shell inner chamber of cylinder block with guide sleeve and cap, and described internal cylinder piston rod inside is cavity, the double cylinder body of doing inner cylinder; Described outer shell piston is installed on the described internal cylinder piston rod, forms piston rod assembly, places described outer shell cylinder body and outer shell guide sleeve inner chamber;
Described inner casing leading in being placed on described internal cylinder piston rod accent, described back guide sleeve places outer cylinder body bonnet endoporus, described guide sleeve pressing plate places on the outer cylinder body bonnet, described inner cylinder piston rod places the endoporus of the preceding guide sleeve of inner casing, back guide sleeve and guide sleeve pressing plate, and adopts step to be fixed on the described guide sleeve pressing plate; Guide sleeve, inner cylinder piston rod are promptly formed a plunger cylinder before described outer oil cylinder piston bar, the inner casing.
On guide sleeve, the back guide sleeve seal ring is housed all before described outer shell guide sleeve, outer shell piston, the inner casing.
Working principle:
1, quick forward motion
Working medium is oil cylinder piston bar inner chamber outside inner cylinder piston rod C mouth enters, because the inner chamber piston rod is fixed in the guide sleeve pressing plate and can't moves, working medium promotes outer oil cylinder piston bar and moves forward.Because the medium supply is constant, internal cylinder piston rod inner chamber area is much smaller than the exocoel piston area, so internal cylinder piston rod is advanced fast.Be same as, also because internal cylinder piston rod inner chamber area much smaller than the exocoel piston area, so this moment oil cylinder working thrust only be the thrust of internal cylinder piston rod inner chamber.Quick voltage supply (low thrust) action is also named in this action.
2, worker's speed forward motion
Working medium is oil cylinder piston bar inner chamber outside inner cylinder piston rod C mouth enters, medium oil cylinder back cavity outside also hydraulic fluid port B mouth enters behind outer cylinder body simultaneously, because the medium supply is constant, oil cylinder cavity volume volume increases, and the working medium one that internal cylinder piston rod enters at C mouth and the B mouth worker's speed that works is down advanced.This moment, the fast total head of worker's (work) (high thrust) action was also named in this action of thrust of oil cylinder.
3, backhaul action
Working medium hydraulic fluid port A mouth before the outer cylinder body enters the outer chamber ante-chamber, the backhaul under operation medium of outer cylinder body piston rod assembly, and the working medium of outer cylinder body back cavity and outer cylinder body piston rod cavity returns into system from B hydraulic fluid port and C mouth respectively.
Compared with prior art, the beneficial effects of the utility model are:
1, the stroke of oil cylinder is the distance that the internal cylinder piston rod guiding is set to piston, not limited by little cylinder.Need not to worry that the oil cylinder that little cylinder stroke causes less than the vat stroke damages.
2, the internal cylinder piston rod inner chamber need not whole processing, only need process afterbody guide sleeve installation position, and processing is simple, saves processing cost.
(4) description of drawings
Fig. 1 is the structural representation of the built-in quick composite oil cylinder of the utility model.
Wherein:
Guide sleeve 6, inner cylinder piston rod 7, back guide sleeve 8, outer cylinder body bonnet 9, guide sleeve pressing plate 10 before internal cylinder piston rod 1, guide sleeve and cap 2, outer shell guide sleeve 3, outer shell cylinder body 4, outer shell piston 5, the inner casing.
(5) embodiment
Referring to Fig. 1, a kind of built-in quick composite oil cylinder that the utility model relates to, it mainly is made up of guide sleeve 6, back guide sleeve 8 and guide sleeve pressing plate 10 before outer cylinder component, inner cylinder piston rod 7, the inner casing.
Above-mentioned outer cylinder component is made up of internal cylinder piston rod 1, guide sleeve and cap 2, outer shell guide sleeve 3, outer shell cylinder body 4, outer shell piston 5.Outer shell guide sleeve 3 places outer shell cylinder body 4 front ends, is installed in outer shell cylinder body 4 inner chambers with guide sleeve and cap 2.Internal cylinder piston rod 1 inside is cavity, the double cylinder body of doing inner cylinder.Outer shell piston 5 is installed on the internal cylinder piston rod 1, forms piston rod assembly, places outer shell cylinder body 4 and outer shell guide sleeve 3 inner chambers.Guide sleeve 6 places accent in the internal cylinder piston rod 1 before the inner casing, back guide sleeve 8 places outer cylinder body bonnet 9 endoporus, guide sleeve pressing plate 10 places on the outer cylinder body bonnet 9, inner cylinder piston rod 7 places the endoporus of the preceding guide sleeve 6 of inner casing, back guide sleeve 8, guide sleeve pressing plate 10, and adopt step to be fixed on the guide sleeve pressing plate 10, play before and after the piston rod when preventing work.Guide sleeve 6, inner cylinder piston rod 7 are promptly formed a plunger cylinder before outer oil cylinder piston bar 1, the inner casing.
On guide sleeve 6, the back guide sleeve 8 seal ring is housed all before outer shell guide sleeve 3, outer shell piston 5, the inner casing.
