Pipeline, the power fluid input duct are connected to by lower hydraulic pressure chamber pipeline with lower hydraulic pressure chamber, and the lower hydraulic pressure chamber top is equipped with can
The piston rod of the piston slided up and down, the piston centre position runs through lower hydraulic pressure chamber, and the piston-rod lower end is fixedly installed with
Stroke adjustment plate, is additionally provided with the valve letter bar that can slide up and down on the hydraulic cylinder of the piston rod side, on the valve letter bar
In lower hydraulic pressure chamber, the valve letter bar passes through commutation hydraulic pressure signal pipe and slide valve bottom chamber, slide valve bottom cavity room at end
In be equipped with slide valve, by upper hydraulic pipeline and upper hydraulic chamber into communication, the slide valve is opposite with upper hydraulic pipeline for the slide valve side
Side is connected with low-voltage-powered liquid pipe road, and the low-voltage-powered liquid pipe road other end is connected on valve letter bar.
As further explanation, the upper hydraulic cavities and lower hydraulic pressure chamber are respectively arranged on upper piston area and lower part.
As further explanation, the power fluid input duct is also connect with valve letter bar.
As further explanation, it is equipped with valve in the middle part of the valve letter bar and believes that bar groove, the valve letter bar groove believe bar with valve
Slide up and down the connection of realization and dynamicliquid pressure pipeline and cutting for commutation hydraulic pressure signal pipe and the connection in low-voltage-powered liquid pipe road
It changes.
Beneficial effects of the present invention:
This stroke is adjustable, and automatic repeatedly hydraulic cylinder can realize row by the relatively reasonable switch valve of power fluid
The adjustable effect of Cheng Zidong, can satisfy the requirement of particular job environment and task.
Detailed description of the invention
Fig. 1 is adjustable automatic one schematic diagram of repeatedly hydraulic cylinder works state of stroke of the present invention；
Fig. 2 is adjustable automatic two schematic diagram of repeatedly hydraulic cylinder works state of stroke of the present invention.
Specific embodiment
Technical solution of the present invention work specifically, is completely illustrated with reference to the accompanying drawing.
As shown in Figure 1:
A kind of adjustable automatic repeatedly hydraulic cylinder of stroke, including hydraulic cylinder, the hydraulic cylinder are equipped with power fluid feed liquor
Pipeline 1, the power fluid input duct 1 are connected to by lower hydraulic pressure chamber pipeline 2 with lower hydraulic pressure chamber 9, and the lower hydraulic pressure chamber top is set
Can slide up and down piston 7, and the piston rod in 7 centre of piston runs through lower hydraulic pressure chamber 9, and the piston-rod lower end is fixed
Stroke adjustment plate 14 is installed, the valve letter bar 10 that can slide up and down, institute are additionally provided on the hydraulic cylinder of 8 side of piston rod
It states valve letter 10 upper end of bar to be in lower hydraulic pressure chamber, the valve letter bar 10 is connected by commutation hydraulic pressure signal pipe 13 and slide valve bottom cavity room 5
It is logical, slide valve 3 is equipped in slide valve bottom cavity room 5,3 side of slide valve is connected to by upper hydraulic pipeline 4 with upper hydraulic cavities 6, institute
It states slide valve 3 and upper 4 opposite side of hydraulic pipeline is connected with low-voltage-powered liquid pipe road 12, low-voltage-powered 12 other end of liquid pipe road
It is connected on valve letter bar 10；The upper hydraulic cavities 6 are respectively arranged on 7 top of piston and lower part with lower hydraulic pressure chamber 9.The power fluid into
Liquid pipe road is also connect with valve letter bar, and valve is equipped in the middle part of the valve letter bar 10 and believes that bar groove 11, the valve letter bar groove 11 are believed with valve
Bar 10 slides up and down the connection of realization and dynamicliquid pressure pipeline 1 and commutate hydraulic pressure signal pipe 13 and low-voltage-powered liquid pipe road 12
The switching of connection.
Embodiment and the working principle of this reversal valve are:
Referring to Fig.1:
When automatic repeatedly hydraulic cylinder progress uplink work that this stroke is adjustable, power fluid enters from power liquid pipe road 1, passes through
Lower hydraulic pressure chamber pipeline 2 enters lower hydraulic pressure chamber 9 and pushes 7 uplink of piston, when the stroke adjustment plate 14 of installation on the piston rod is up to
When top dead centre, push valve believe 10 uplink of bar, valve believe bar groove 11 also therewith uplink and with 1 connection of high voltage power liquid pipe road, make height
Pressure medium enters commutation signal pipe 13 and slide valve bottom cavity room 5, and since the floor space of slide valve 3 is bigger than top area, suffered is pushed away
Power is also big, so 3 uplink of slide valve is pushed, the relationship of 2 power fluid high-low pressure of hydraulic lumen road 4 and lower hydraulic pressure chamber pipeline in switching,
Make hydraulic cylinder automatic reverse.
Referring to Fig. 2:
When automatic repeatedly hydraulic cylinder progress uplink work that this stroke is adjustable, when piston 7 goes downwards to lower dead center, valve is pushed
Believe 10 downlink of bar, valve believes the also downlink therewith of bar groove 11, makes reversal valve hydraulic pressure signal pipe 13 and low-voltage-powered 12 connection of liquid pipe road,
Make 5 internal hydraulic pressure medium of slide valve bottom cavity room be discharged to form low pressure, pushes slide valve 3 under the action of upper pressure and exercised under slide valve
Reversal valve commutation.
This stroke is adjustable, and automatic repeatedly hydraulic cylinder can realize row by the relatively reasonable switch valve of power fluid
The adjustable effect of Cheng Zidong, can satisfy the requirement of particular job environment and task.
Obviously, described embodiment is only a part of the embodiments of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, all other reality obtained by those of ordinary skill in the art without making creative efforts
It applies, belongs to protection scope of the present invention.
