Abstract
The invention provides a hydraulic cylinder assembly. The hydraulic cylinder assembly comprises a supporting disc, a guide sleeve, a cylinder barrel, a piston rod, a cover plate, a connecting plate, screws, a seal ring assembly and a deflation valve. A groove is formed in the middle of the supporting disc, the connecting plate is clamped in the groove, a sphere is arranged at the end of the piston rod, the connecting plate is of a split structure, a spherical cavity is formed in the split connecting plate, the sphere at the end of the piston rod is stuffed into the spherical cavity, and then the split connecting plate is fixed through the screws. The end of the cylinder barrel is connected with the cover plate, and the deflation valve is arranged on the cover plate. The hydraulic cylinder assembly can overcome the defect of loading capacity imbalance caused by movement in two directions.
Description
Technical field
The present invention relates to a kind of hydraulic pressure cylinder assembly, belong to field of mechanical technique.
Background technique
Piston-type hydraulic cylinder can be divided into single lever-type and double rod type two kinds of structures, and its means of fixation fixes two kinds by cylinder body is fixing with piston rod, has single-acting formula and double action by the operative condition of hydraulic coupling.In single-acting formula oil hydraulic cylinder, pressure oil only supplies a chamber of oil hydraulic cylinder, makes cylinder realize unidirectional motion by hydraulic coupling, and motion in the other direction then outer power (as spring force, deadweight or external load etc.) realizes; The motion of double-acting hydraulic cylinder piston both direction then replaces oil-feed by two chambeies, being used for by hydraulic coupling.It is only provided with piston rod in the side of piston, and thus the effective active area in two chambeies is different.When fuel delivery is identical, different cavity oil-feed, the movement velocity of piston is different; When the load force that need overcome is identical, different cavity oil-feed, required charge oil pressure is different, and in other words after system pressure is set up, oil hydraulic cylinder both direction move the load force difference that can overcome.
Summary of the invention
The invention provides a kind of hydraulic pressure cylinder assembly, is the hydraulic pressure cylinder assembly that a kind of structural capacity is stronger.
For solving above technical problem, the invention provides following technological scheme: a kind of hydraulic pressure cylinder assembly, comprise supporting disk, guide sleeve, cylinder barrel, piston rod, cover plate, connecting plate, screw, seal ring assembly and bleed valve, fluted in the middle part of described supporting disk, connecting plate is stuck in groove, and piston rod end has spheroid, connecting plate is Split type structure, have spherical hollow space in the connecting plate of split, the spheroid of piston rod end is filled in this spherical hollow space, then is fixed by the connecting plate of screw by split; The end of cylinder barrel connects cover plate, and cover plate is provided with bleed valve.
Further, between described cylinder barrel and piston rod, there is guide sleeve; Be connected by screw between guide sleeve with cylinder barrel, screw is arranged on guide sleeve cross section end.
Further, between described cylinder barrel and piston rod, there is seal ring assembly.
This hydraulic pressure cylinder assembly that the present invention relates to, can overcome the move load force that causes of both direction unbalanced.
Accompanying drawing explanation
Fig. 1 is a kind of hydraulic pressure cylinder assembly structural drawing of the present invention.
