The gas-liquid damping cylinder provided by the utility model not only can realize mechanical workout with the rapid advance phase, the feeding phase and the rapid return phase, but also has a perceived reduction in the overall length, thereby greatly facilitating manufacturing, installation and usage of the gas-liquid damping cylinder.
Description
Technical field
The utility model relates to " F.F., worker advance, rewind down " that is applied in lathe and the machine cut processing, particularly separately makes both be the gas-liquid damping cylinder of on-fixed linkage structure in gas piston and oily piston.
Background technique
Gas-liquid damping cylinder is to be power source with pressurized air, drives when the damping regulating action of cylinder by the oil cylinder of sealing obtains cutting to move reposefully, is mainly used in lathe and machine cut processing, realizes desired " F.F., worker advance, rewind down ".As shown in Figure 1, two of all whole tandem gas-liquid damping cylinders pistons at present, i.e. so gas piston 5 ' and the oily piston 6 ' interlock that all links together is the length of whole tandem gas-liquid damping cylinder twice of approaching identical stroke (being CC) cylinder all.In addition, advancing of instrument often needs two speed in machine cut processing: required its rapid movement (being F.F. stroke KJ) before the instrument contact workpiece, when arriving workpiece, the requirement instrument is with the cutting speed motion (being that the worker carries out journey GJ) of regulation, fast return after the process finishing (being rewind down stroke KT).Yet present whole tandem gas-liquid damping cylinder is difficult to accurately to accomplish this point, it otherwise be F.F., rewind down, this obviously is that all cuttings are all unallowed; All be that slow-motion is moved back slowly, rhythm of production does not allow so to do yet.
The model utility content
The purpose of this utility model provides the gas-liquid damping cylinder of the stable cutting of a kind of realization the " F.F., worker advance, rewind down " feeding.
For solving the problems of the technologies described above, gas-liquid damping cylinder of the present utility model includes: an actuating cylinder, and the one axial end portion is equiped with the gas piston, and the inside of this actuating cylinder also is provided with the piston rod that links with described gas piston; One ventilation mechanism, it comprise with first gas port of described gas piston UNICOM and with second gas port of another axial end portion UNICOM of described actuating cylinder; Also include: a damping oil cylinder, itself and described actuating cylinder are by Bolt Connection, and the inside of this damping oil cylinder is provided with oily piston, and described piston rod passes through from this oil piston intermediate hole; And an oil damping mechanism, it goes out oil damping is realized by the series flow control valve of the prior art of outside, realizes quick oil return by the one-way valve that is installed on the oily piston.
As a kind of preferred version of the present utility model, described oily piston center symmetry is installed in the periphery of described piston rod, also is equiped with straight pin on described piston rod, and the outer end of this straight pin and described piston rod links.
As a kind of preferred version of the present utility model, described fuel-displaced mechanism comprises first hydraulic fluid port that is positioned at the right chamber of described damping oil cylinder, second hydraulic fluid port that is positioned at chamber, a described damping oil cylinder left side and the series flow control valve that connects described first hydraulic fluid port and second hydraulic fluid port.
As a kind of preferred version of the present utility model, between described second hydraulic fluid port and series flow control valve, also connect a fuel tank by an one-way valve.
As a kind of preferred version of the present utility model, described oil return mechanism comprises that one is positioned at the one-way valve of described oily piston, this one-way valve and described damping oil cylinder UNICOM.
Technique effect of the present utility model is, makes gas-liquid damping cylinder realize the machining flow process of " F.F., worker advance, rewind down ", and simple, convenient, reliable.
Technique effect of the present utility model is again, because oily piston is non-rigid the connection with the gas piston, the oil piston only plays " damping " effect when " worker advances ", so its stroke is the distance of " worker advances " just, it is identical with actuating cylinder that this makes that the length of damping oil cylinder does not need, this has just shortened the length of whole gas-liquid damping cylinder greatly, and this manufacturing to gas-liquid damping cylinder, installation, use bring great convenience.

Embodiment
As shown in Figure 2, gas-liquid damping cylinder structure of the present utility model comprises actuating cylinder 1, damping oil cylinder 2 and series flow control valve 3 three parts.
Actuating cylinder 1 and damping oil cylinder 2 usefulness bolts are chained together.When pressurized air enters actuating cylinder 1 from first gas port 4, gas piston 5 is rapid movement to the right, contact oily piston 6 after, head on oily piston 6 and continue to move right, movement velocity at this moment is subjected to oily piston 6 restrictions (being referred to as " damping ").The oil in the right chamber of damping oil cylinder flows out by first hydraulic fluid port 7, through the left chamber of series flow control valve 3, second hydraulic fluid port, 8 inflow damping oil cylinders 2, the size of control series flow control valve path is with regard to the speed of adjustable fuel-economizing piston 6 motions, just control simultaneously the speed of gas piston 5 motions, at this moment just entered " worker advances " stage.Any position in " worker advances " stage, all can send signal by outer member makes gas circuit commutate, pressurized air enters actuating cylinder 1 from second gas port 9, gas piston 5 is rapid movement left, straight pin 11 on being installed on piston rod 10 is being with oily piston 6 together when left movement, the oil in the left chamber of damping oil cylinder 2 resets a loop ends by the one-way valve 12 quick right chambeies that flow into damping oil cylinder 2 up to gas piston 5.
