Description
Technical field
The utility model is related to a kind of stroke measurment signal output formula hydraulic cylinder, being capable of output hydraulic pressure cylinder piston stroke in real time
The data-signal of amount, belongs to technical field of hydraulic equipment.
Background technology
Current engineering machinery automation, electromechanical integral automatic, it is often necessary to portions such as equipment and running gears
Pistons work stroke in the hydraulic jack of position carries out Detection ＆ Controling.
Piston stroke detecting method in known hydraulic jack is the outside or inside installation displacement sensing in hydraulic cylinder
Device.
Outside in hydraulic cylinder installs displacement transducer, and change that can be by measuring hydraulic cylinder external hydraulic pole length is obtained
Take the travel information of hydraulic piston, this mode due to need take hydraulic cylinder exterior space, and install it is more complicated, external force and
The environment and small space that other factors potentially affect sensor element are unsuitable for this kind of mode.
The mode of displacement sensor is installed inside hydraulic cylinder can cause hydraulic cylinder inner mounting structure to complicate, and cost is high,
Stability is poor, and maintenance maintenance is all very difficult.
The content of the invention
In order to overcome the shortcomings of that existing hydraulic cylinder travel e measurement technology is present, the utility model provides a kind of stroke measurment
Signal output formula hydraulic cylinder, the hydraulic cylinder is not only simple in structure, cheap, and certainty of measurement is high, does not take outside hydraulic cylinder additionally
Portion space, and maintenance maintenance is convenient.
The technical scheme that the utility model is used is：The composition of stroke measurment signal output formula hydraulic cylinder includes, hydraulic pressure
Cylinder body, hollow piston rod, open-work piston, alignment pin, groove guide rod, angular transducer, groove guide rod pass through open-work piston, are placed in
Inside hollow piston rod, coordinated using gap between the two, groove guide rod is provided with curve guide groove, and one end is worn with sealing attachment
Cross hydraulic cylinder bottom, it is ensured that the closed and groove guide rod of hydraulic cylinder bottom can be moved in a rotative pattern, and alignment pin is fixed on piston
Bottom, one end is placed in the curve guide groove of groove guide rod, and angular transducer one end is fixed with support, one end with pass through cylinder bottom
The rotatable groove guide rod connection in portion.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples；
Fig. 1 is vertical section organigram of the present utility model；
Fig. 2 is that hydraulic cylinder piston of the invention is run to the structural representation of range half position；
Fig. 3 is the A-A sectional views of Fig. 1；
Fig. 4 is the B-B sectional views of Fig. 2；
In Fig. 1：1 hydraulic cylinder, 2 hollow hydraulic stems, 3 open-work pistons, 4 groove guide rods, 5 alignment pins, 6 curve guide grooves, 7 jiaos
Degree sensor.
Specific embodiment
In using the embodiment of such scheme, as shown in figure 1, in groove guide rod（4）360 degree of songs of spiral surrounding of upper setting
Line guide groove（6）, curve guide groove（6）One end originates in open-work piston（3）In hydraulic cylinder（1）The position alignment pin of bottom original position
（5）With groove guide rod（6）Cooperation at, the other end terminates in groove guide rod（4）Top, now groove guide rod（4）Passed with angle
Sensor（7）The section state of connecting portion 4A is as shown in Figure 3.
When open-work piston（3）Promote hollow hydraulic stem（2）When travelling forward, as shown in Fig. 2 being located at open-work piston（3）Bottom
The alignment pin in portion（5）, along curve guide groove（6）Relative slip is done, due to alignment pin（5）Positioning action and curve guide groove（6）'s
Guide effect, causes open-work piston（3）While moving along a straight line, groove guide rod（6）Rotary motion is supervened, groove is led
Bar（4）Rotary motion then drive angular transducer（7）Rotate, angular transducer（7）Corresponding mould is exported according to the anglec of rotation
Intend or data signal, the stroke measurment data of hydraulic piston can be in real time provided for industrial control equipment.
In this embodiment, due to alignment pin（5）In curve guide groove（6）In maximum sliding distance respective slot guide rod（4）
The maximum anglec of rotation be 360 degree, so angular transducer（7）The variable quantity for often exporting once then shows open-work piston（3）Institute
Mobile distance is 1/the 360 of range, when open-work piston（3）When row is to range half position, supervene recessed
Groove guide rod（4）180 degree is rotated, now groove guide rod（4）With angular transducer（7）Section state such as Fig. 4 institutes of connecting portion 4A
Show.
Using such scheme, following beneficial effect can be reached：1st, just can be adjoint by the linear motion of hollow hydraulic stem
The rotary motion of groove guide rod is produced, and drives angular transducer to export the analog or digital signal of anglec of rotation change, realized
The stroke real-time detection of hydraulic piston.Simple structure is cheap, it is easy to safeguard and data are accurate.2nd, can be different by designing
The curve guide groove of spiral angle realizes exporting the analog or digital signal of the different maximum anglecs of rotation.
