Description
Technical field
The invention belongs to pneumatics field, more particularly to a kind of blow cylinder device.
Background technology
In some applied environments, such as aircraft load ejection is realized in delivering wind tunnel experiment, it is necessary to take less space
Larger thrust promotes other devices, and need in the case where cylinder piston stroke is constant on a large scale (maximum 50% with
On) regulation output work.Conventional air cylinder device can adjust thrust and single output work by adjusting supply gas pressure, but due to
The compressibility of gas, the lateral pressure of piston one is improved as the gaseous mass by valve, pressure-regulating device increases,
When pressure rises to certain value, when piston thrust is more than frictional force, piston just has begun to motion, by traditional valve stream
Amount, pressure regulation device flow restriction, the quick motion of piston limit the speed of the lateral pressure of piston one raising, limit whole
Piston thrust in working stroke, is unfavorable for that piston single promotes the raising of output work.And the blow cylinder structure of routine makes it
Substantially do not possess the ability of output work regulation.
The content of the invention
It is an object of the invention to：For above-mentioned problem, there is provided a kind of unit volume thrust, unit volume single
Output work is higher and single output work adjustable impact air cylinder device.
The technical proposal of the invention is realized in this way：A kind of blow cylinder device, including cylinder, it is characterised in that：Institute
State cylinder to be connected with energy accumulation container, be provided with for stopping that piston rod is transported on the movement position of piston rod in the cylinder
Dynamic blocking mechanism, the blocking mechanism prevented piston movement before cylinder interior gas pressure reaches designated value, when in cylinder
When gas pressure reaches designated value, the blocking mechanism releases the stop to piston rod, and the piston rod is in specified gas pressure
Lower motion.
Blow cylinder device of the present invention, its described energy accumulation container is connected by pipeline with cylinder block internal cavity
Lead to, or the energy accumulation container is connected directly between on cylinder, or hold the part cavity in the cylinder block as accumulation of energy
Device.
Blow cylinder device of the present invention, its described blocking mechanism includes piston rod stopper, the piston rod resistance
The flange or groove corresponding matching set on block and piston rod, the piston rod stopper is connected with drive mechanism, described
Before cylinder interior gas pressure reaches designated value, the piston rod stopper is resisted against at the flange of piston rod or is placed in piston
In the groove of bar, to prevent piston rod movement, when the cylinder interior gas pressure reaches designated value, the piston rod stopper
In the presence of drive mechanism, with piston rod on flange or groove depart from and release stop to piston rod, the piston rod
Moved in the case where gas pressure is specified.
The setting that the present invention passes through blocking mechanism, can prevent piston movement before gas pressure reaches designated value, make
With gas pressure higher when piston movement starts, while by setting energy accumulation container, being conducive to during piston movement
Slow down the pressure loss, when energy accumulation container volume is sufficiently large, the maintenance of pressure can rely primarily on energy accumulation container during piston movement,
Then valve, the latus rectum of pressure-regulating device, traffic requirement can be reduced, and advantageously reduce system weight and system cost, be passed through
Blocking mechanism and the cooperation of energy accumulation container, make piston single output work tend to linear with gas pressure, and be conducive to piston single
The regulation of output work.
