Abstract
The invention provides an arrangement type loading oil cylinder, and aims at solving the problem of non-uniform loading effect in synchronous multi-point loading or driving of a plurality of common hydraulic loading oil cylinders in the prior art, as well as ensuring safe and reliable loading of parts. The arrangement type loading oil cylinder is characterized by comprising a front end cover, a rear end cover and at least two piston rod assemblies, wherein hydraulic oil cavities are formed in the front end cover and the rear end cover; each piston rod assembly comprises a cylinder barrel and a piston rod; two ends of each cylinder barrel are correspondingly connected to the front end cover and the rear end cover, and oil outlets in the two ends of each cylinder barrel correspondingly communicate with the hydraulic oil cavities in the front end cover and the rear end cover; a piston is arranged on each piston rod; the piston rods sequentially pass through the front end cover, the cylinder barrel and the rear end cover; the pistons are positioned in the cylinder barrels and can move up and down in the cylinder barrel when the piston rods move.
Description
Technical field
The present invention relates to hydraulic control device field, be specially arranged type load cylinder.
Background technique
In art technology, adopt multiple Normal hydraulic load cylinder multiple spot to load parts often when needing comparatively flat to one or that length is longer parts to load or drive simultaneously, but the plurality of hydraulic stroker is all drive to be loaded, so it exists load the uneven problem of distribution of forces, thus easily cause the effect that maybe cannot reach uniform load or smooth drive to the damage of loading component.
Summary of the invention
For the problems referred to above, the invention provides arranged type load cylinder, its loading that can solve the form existence that existing employing multiple Normal hydraulic load cylinder multiple spot loads simultaneously or drives acts on uneven problem, ensures the safe and reliable loading to parts.
Arranged type load cylinder, it is characterized in that: it comprises front cover, rear end cover and at least two group piston rod assemblies, described front cover, rear end cover all has hydraulic fluid chamber, described piston rod assembly comprises cylinder barrel and piston rod, the two ends of described cylinder barrel respectively with described front cover, rear end cover connect and the oil outlet at described cylinder barrel two ends respectively with described front cover, the hydraulic fluid chamber UNICOM of rear end cover, described piston rod is provided with piston, described piston rod runs through described front cover successively, cylinder barrel and rear end cover, described piston is positioned at described cylinder barrel and can moves up and down at described cylinder barrel along with the movement of piston rod.
Further, it also comprises bottom head covers, described piston rod assembly also comprises secondary cylinder barrel, one end of described secondary cylinder barrel is installed on the bottom of described rear end cover, the other end is sealed by described bottom head covers, and described secondary cylinder barrel is arranged with described cylinder barrel is concentric, the bottom of described piston rod is stretched in described secondary cylinder barrel.
Beneficial effect of the present invention is: its be provided with at least two group piston rod assemblies and the two ends hydraulic pressure oilhole of each piston rod assembly respectively with the hydraulic fluid chamber UNICOM of front cover, rear end cover, thus make the loading force of the piston rod of each piston rod assembly identical, namely reach the effect of each piston rod uniform load or smooth drive.
