Description
Technical field
The utility model is related to a kind of buffer unit of double-acting cylinder.
Background technology
Realize that the structure of the pooling feature of double-acting cylinder is complex at present, fault rate is high, and effectively cushion stroke
Compare short, it is impossible to be adjusted, it is limited using scope.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of structure novelty, the double-acting cylinder of good buffer effect
Buffer unit.
The utility model is realized using following scheme：A kind of buffer unit of double-acting cylinder, including with cylinder two ends phase
The first tracheae and the second tracheae of connection, the first air supply pipe for being connected with source of the gas and the second air supply pipe and with outside air phase
Logical the first escape pipe and the second escape pipe, first tracheae is through both magnetic valve A and the first air supply pipe and the first escape pipe
A connection is selected, second tracheae is connected through magnetic valve B with the second air supply pipe and the second escape pipe either-or；First tracheae,
Choke valve is provided with second tracheae, the first escape pipe and the second escape pipe.
Further, in addition to sense cylinder stretch out when first position sensor and to sense cylinder withdraw when
Second place sensor.
Compared with prior art, the utility model has the advantages that：The buffering of the utility model double-acting cylinder
Apparatus structure is simple, reasonable in design, not only good buffer effect, significantly extension cylinder service life, and can having to buffering
Effect stroke is adjusted, easy to use.
For the purpose of this utility model, technical scheme and advantage is more clearly understood, specific embodiment will be passed through below
And relevant drawings, the utility model is described in further detail.
Brief description of the drawings
Fig. 1 is the utility model embodiment organigram；
Label declaration in figure：1- cylinders, the tracheaes of 2- first, the tracheaes of 3- second, 4- sources of the gas, the air supply pipes of 5- first, 6- second
Air supply pipe, the escape pipes of 7- first, the escape pipes of 8- second, 9- magnetic valve A, 10- magnetic valve B, 11- choke valve, 12- first positions are passed
Sensor, 13- second places sensor.
Embodiment
As shown in figure 1, a kind of buffer unit of double-acting cylinder, including the first tracheae 2 for being connected with the two ends of cylinder 1 and
Second tracheae 3, the first air supply pipe 5 being connected with source of the gas 4 and the second air supply pipe 6 and the first outlet communicated with outside air
The escape pipe 8 of pipe 7 and second, first tracheae 2 connects through magnetic valve A9 and the first air supply pipe 5 and the either-or of the first escape pipe 7
Logical, second tracheae 3 is connected through magnetic valve B10 with the second air supply pipe 6 and the either-or of the second escape pipe 8；First tracheae 2,
Choke valve 11 is provided with second tracheae 3, the first escape pipe 7 and the second escape pipe 8, wherein the first tracheae 2 and cylinder right chamber
It is connected, the second tracheae 3 is connected with cylinder left chamber, the utility model passes through air inlet gas circuit and the choke valve quantity of outlet gas circuit
It is different so that cylinder piston rod is when moving to certain position so that the air pressure of cylinder exhaust intracavitary moment can be more than air inlet
The air pressure of chamber, plays a part of buffering.
In the present embodiment, magnetic valve A and magnetic valve B are two-bit triplet magnetic valve.
In the present embodiment, in addition to sense cylinder stretch out when first position sensor 12 and to sense cylinder
Second place sensor 13 during withdrawal, first position sensor 12 and second place sensor 13 are connected with PLC control unit
Connect.
The utility model embodiment course of work：When system just starts to start, and cylinder is in withdrawal piston rod state,
PLC control unit controls magnetic valve A, the first tracheae and the first escape pipe is connected, then cylinder right chamber air pressure inside is down to greatly
Air pressure level, while PLC control unit controls magnetic valve B, makes the second tracheae be connected with the second air supply pipe, cylinder piston rod is fast
Speed is stretched out, because cylinder left chamber intake velocity is more than the exhaust velocity of right chamber, when piston rod reaches certain position, in cylinder right chamber
The air pressure moment in portion is more than the air pressure inside cylinder left chamber, provides steady buffering for cylinder using the compressibility of air, plays
The effect of buffering；When cylinder is in stretching state, PLC control unit control magnetic valve B makes the second tracheae and the second escape pipe phase
Connect, then cylinder left chamber leads to air, cylinder left chamber air pressure inside is down to atmospheric pressure, while PLC control unit controls electromagnetism
Valve A, makes the first tracheae be connected with the first air supply pipe, cylinder piston rod is quickly withdrawn, because cylinder right chamber intake velocity is more than a left side
Chamber exhaust velocity, when piston rod reaches certain position, the air pressure moment inside cylinder left chamber is more than the air pressure in the intraoral portion of right chamber,
Steady buffering is provided for cylinder using the compressibility of air, plays a part of buffering；The effective travel of above-mentioned buffering can lead to
The choke valve crossed on the first escape pipe and the second escape pipe is controlled.
Above-listed preferred embodiment, the purpose of this utility model, technical scheme and advantage are further described,
It should be understood that and the foregoing is only preferred embodiment of the present utility model, it is all not to limit the utility model
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. should be included in this practicality
Within new protection domain.
