Abstract
The invention discloses a hydraulic servo hinge which belongs to a hydraulic driving device. The hydraulic servo hinge comprises a sealing cover and a fixed spline shaft, wherein the fixed pline shaft is arranged at one side of a bearing, the other side of the bearing is provided with a piston rod, the piston rod is connected with a piston, a hydraulic cylinder is arranged outside the piston, a guide rail is arranged in the hydraulic cylinder, both ends of the guide rail are arranged on the fixed spline shaft, a thrust bearing is arranged on the hydraulic cylinder, a cam is arranged outside the thrust bearing, a groove mutually matched with the thrust bearing is arranged on the cam, and a rotary spline sleeve shaft is arranged outside the cam. The hydraulic servo hinge is driven by hydraulic pressure, has low power and simple structure and changes the straight reciprocating movement of a hydraulic press into the reciprocating rotation around the hydraulic press, integrates the hydraulic press and a cam transmission mechanism, forms a hinge shaft type hydraulic angle/swinging actuator, and has the advantages of fixed hydraulic press stroke, large hinge rotating angle range and no dead work angle.
Description
Technical field
The invention belongs to fluid pressure drive device, be specifically related to a kind of hydraulic servo hinge.
Background technology
At present, the driving that the large sealing cover is opened, closed, or adopt outside the assembled hydraulic cylinder of rotary actuator, oscillating motor, the rotation of piston-rack driven gear, or adopt hydraulic press promotion connecting rod to drive the complicated transmission mechanism that sways.The assembled hydraulic cylinder that traditional rotary actuator, oscillating motor, piston-rack driven gear rotate etc., general power is little, and structural volume is bigger, be used for difficulty, the especially more difficult employing of nozzle lid structure space condition of limited of driving control ratio that the large sealing cover opens and closes.Drive the complicated transmission mechanism that the large sealing cover opens and closes for adopting hydraulic press to promote connecting rod, the guiding that promotes connecting rod needs certain nozzle lid height, otherwise the cover opening angle can be very limited, exist to rotate the dead angle: when nozzle covers when height-limited, be difficult to adopt hydraulic press to promote linkage and realize that the wide-angle of cover opens, just be difficult to realize that as the cover of submarine-based missile emitter wide-angle opens.Performer/mechanism for the high-power direct driving of hydraulic pressure that realizes installing in the confined space is swayed needs the hydraulically powered angle/swing actuator of a kind of hinge shaft type.
Summary of the invention
The problem that the problem to be solved in the present invention is that the opening and closing of large sealing cover are little with drive unit power, volume is big, exist working angle provides that a kind of power is little, simple in structure, the hydraulic servo hinge of no working angle.
Technical scheme of the present invention realizes with following method:
A kind of hydraulic servo hinge, comprise seal cover and the fixedly splined shaft that is arranged on bearing one side, the bearing opposite side is provided with piston rod, piston rod connects piston, and piston is provided with hydraulic cylinder outward, is provided with guide rail in the hydraulic cylinder, the guide rail two ends are arranged on fixedly on the splined shaft, hydraulic cylinder is provided with thrust bearing, and thrust bearing is provided with cam outward, and cam is provided with the groove that matches with thrust bearing; Cam is provided with outward and rotates the spline sleeve.
Described thrust bearing is one.
Described thrust bearing is two.
The present invention is being provided with guide rail in hydraulic cylinder, guide rail has limited hydraulic cylinder can only be along the translational motion of piston rod direction, and can not rotate around piston rod; The bearing that is provided with on the hydraulic cylinder matches with inclined-plane on the cam, during the hydraulic cylinder move left and right, drives cam and moves along the direction of groove, finally rotates around piston rod.Compared with prior art, the present invention is little, simple in structure by hydraulic-driven power, the straight reciprocating motion of hydraulic press is become reciprocal rotation around hydraulic press, make hydraulic press and cam drive integrated, constitute a kind of hydraulic pressure angle/swing actuator of hinge shaft type, the hydraulic press stroke is fixed, and the hinge angle range is big, no working angle.

The specific embodiment
As depicted in figs. 1 and 2, the present invention includes seal cover 10 and the fixedly splined shaft 1 that is arranged on bearing 2 one sides, bearing 2 opposite sides are provided with piston rod 6, and piston rod 6 connects pistons 4, the piston 4 outer hydraulic cylinders 8 that are provided with.Be provided with guide rail 3 in the hydraulic cylinder 8, guide rail 3 two ends are arranged on fixedly on the splined shaft 1, and hydraulic cylinder 8 is provided with thrust bearing 5, and thrust bearing 5 is outer to be provided with a cam 9, and cam 9 is provided with the groove 11 that matches with thrust bearing 5; Cam 9 outer being provided with are rotated spline sleeve 7.
The present invention includes hydraulic press, cam, the piston rod 6 of hydraulic press is fixing, is the fixed axis of hydraulic servo hinge.Piston rod 6 adopts hollow structure, and two ends are into and out of hydraulic fluid port.Hydraulic cylinder 8 is the push rod of special cam, and hydraulic cylinder 8 moves back and forth along piston rod 6 under hydraulic-driven, and the mobile of hydraulic cylinder 8 can not be rotated by guide rail 3 constraints.Cam 9 is enclosed within on the hydraulic cylinder, and hydraulic cylinder 8 moves back and forth, and under the effect of thrust bearing 5 and groove 11, cam 9 back and forth rotates around hydraulic press.Rotate spline sleeve 7 and be linked on the cam 9, connect firmly with cam 9.The present invention becomes reciprocal rotation around hydraulic press with the straight reciprocating motion of hydraulic press, makes hydraulic press and cam drive integrated, constitutes a kind of hydraulic pressure angle/swing actuator of hinge shaft type.The present invention is simple in structure, working stability, reliable, simple installation, maintenanceability is good, and the hydraulic press stroke fixes, and the hinge angle range is big, can be used for the opening or close of large sealing cover, door, ball valve and butterfly valve, can also be used for the deflection driven of rudder plate around axle.
As shown in Figure 3, described thrust bearing 5 is two, and the groove 11 that matches with plunger on the cam 9 is two; Perhaps described thrust bearing 5 is three or a plurality of, and other are with embodiment 1.
