Description
Technical field
This utility model relates to one and includes on-fluid type spring and vibroshock, is specifically related to a kind of gas spring device with self-cleaning function.
Background technology
Air spring (gasspring) is a kind of industry accessories that can play the functions such as support, buffering, braking, altitude mixture control and angular adjustment.It is made up of following several parts: pressure cylinder, piston rod, piston, seal guide sleeve, implant (noble gas or gas mixture), controls element and cylinder outer control element (referring to controllable gas spring) and joint etc. in cylinder.Principle is to be filled with noble gas or gas mixture in airtight pressure cylinder, make pressure in cavity higher than atmospheric several times or tens times, utilize the cross-sectional area of the piston rod cross-sectional area less than piston thus the pressure differential produced is to realize the motion of piston rod.Due to the fundamental difference in principle, air spring has significant advantage than common spring: speed is relatively slow, dynamic force changes little (within being typically in 1:1.2), is easily controlled.
Air spring in existing use, its piston rod one end is inserted in pressure cylinder, the other end is exposed outside, such structure has the disadvantage in that exposed piston rod can not be protected, have in the production environment of more dust at some, exposed piston rod is very easy to long-pending full dust, and the piston rod that surface is stained with dust is understood frequently and seal guide sleeve friction, existence with dust, coefficient of friction in friction process is big, it is easily caused piston rod and seal guide sleeve damages, so needing often to check and keep in repair, and decrease the service life of air spring.
Utility model content
The purpose of this utility model is in that providing a kind of can clear up the gas spring device with self-cleaning function that piston rod stretches out the dust of pressure cylinder end surface.

The principle of this programme: time specifically used, when passing into compressed gas source in pressure cylinder, pressure in pressure cylinder continues to raise, compressed gas source promotes piston to move, piston driving piston cylinder moves and piston rod is released pressure cylinder simultaneously, gas pressure sensor detects the pressure in pressure cylinder in real time, and pressure is vertically sent to controller, after the gas pressure in pressure cylinder is constant, when the pressure value that gas pressure sensor detects is stablized, controller controls electric control valve and opens, now the source of the gas of pressure cylinder passes into compression gas in pneumatic tube, compression gas sprays from jet mechanism, dust on piston rod is blown away.
The advantage of this programme is: in this programme, have additional cleaning structure, automatically controlled by gas pressure sensor and controller, by jet mechanism, the piston rod stretching out pressure cylinder is carried out jet, the dust being attached to piston rod surface is blown away, thus can reduce the dust of the adhesion of piston rod surface, in piston rod and the frequent friction process of pressure cylinder, because there is no that dust adheres on the piston rod, so piston rod is less with seal guide sleeve friction, it is not easily caused piston rod and seal guide sleeve damages, without frequent maintenance, thus extending the service life of air spring.
Prioritization scheme 1, the further optimization to base case, described jet mechanism is air nozzle, and the direction of pressure cylinder is stretched out in the jet direction of this air nozzle towards piston rod.The gas pressure sprayed by air nozzle is high, can effectively be blown away by the dust that piston rod surface adheres to.
Prioritization scheme 2, further optimization to base case, described jet mechanism is air jet pipe cylindrically, cavity it is provided with in air jet pipe, air jet pipe is offered the air inlet connected with cavity, this air inlet is connected with pneumatic tube, is enclosed within piston rod near cylinder side, and offers the fumarole that some and described cavity connects on air jet pipe inwall outside described air jet pipe.During use, the gas in pneumatic tube enters in cavity through air inlet, finally sprays from fumarole, due to air jet pipe be overcoat on the piston rod, the gas sprayed by fumarole can blow in piston rod circumference, it does not have cleaning dead angle, blows away the better effects if of dust.
Prioritization scheme 3, the further optimization to prioritization scheme 2, described fumarole is in tilted layout, and stretches out the side of pressure cylinder towards piston rod.When fumarole is in tilted layout in a manner described, it is also tilt that the gas of blowout acts on the power of piston rod surface, and so can directly blow off piston rod by dust.
Prioritization scheme 4, the further optimization to base case, prioritization scheme any one of 1-3, described electric control valve is electromagnetic valve.Electromagnetic valve has response rapidly, controls sensitive feature, it is simple to accurately control.
