Description
Technical field
The present invention relates to a kind of hydraulic control, belong to mechanical-hydraulic compound gearing, be mainly used in two works in machine driving or positioning hydraulic cylinders
The position asynchronous flexible control of both-end.
Background technology
In various hydraulic actuators, two station acting cylinder are the most frequently used mechanisms, when run into needs the two asynchronous transmitting movements of station both-end or
During location, it is substantially employing mechanical transmission structure or two independent hydraulically controlled cylinders realize.
Summary of the invention
For more preferably realizing the two asynchronous flexible controls of station both-end in machine driving or location, the present invention provides a kind of asynchronous telescopic hydraulic cylinder of dibit, should
The control accurate positioning of hydraulic cylinder is reliable, by hydraulic pressure programme-control without manual operation.
The technical scheme is that for machine driving or location control the asynchronous telescopic hydraulic cylinder of dibit, including sealing ring, screw, piston shaft,
End cap, pipe joint, cylinder body.Coaxially being independently arranged about described hydraulic cylinder body lumen orifice, the dividing plate in the middle of cylinder body limits stopping of piston shaft position
Only, described piston shaft has two to be distributed on cylinder body both sides, and piston shaft piston portion coordinates with cylinder inner bore, and end cap has two to be arranged in cylinder body respectively
Both sides, described piston shaft stretches out from the endoporus of two ends end cap, and described pipe joint is arranged on cylinder body excircle, at cylinder interior end cap
Forming inner chamber with piston shaft, form inner chamber at centre position cylinder inner bore and two piston axle heads, described piston shaft and end cap endoporus are provided with sealing
Circle, piston shaft cylindrical, end cap and cylinder inner bore are provided with sealing ring antiseep.Described piston shaft can be positioned at chamber with axially-movable in inner chamber of cylinder block
The step end face position in hole.
During application, hydraulic oil enters hydraulic cylinder coelomopore by pipe joint, and it is each that the change that in four pipe joints, hydraulic oil is connected controls two piston shaft
From location-independent, two piston shaft effect ends overhang out and realize the two asynchronous telescopic variation of station outside cylinder body.
