Abstract
The invention discloses a hydraulic cylinder stroke display device which comprises a pull rope type displacement sensor and a scale plate pointer mechanical portion. The displacement of a hydraulic cylinder piston is converted into an electrical signal through the pull rope type displacement sensor, and a hydraulic cylinder stroke is displayed on an operating panel in real time. The scale plate pointer mechanical mechanism consists of a guide rod, a guide frame, a steel wire, a scale plate, a guide groove, a pointer, a spring winding drum and the like, wherein one end of the steel wire is connected with the hydraulic cylinder piston through the guide rod and the guide frame, the other end of the steel wire is connected with the pointer, the pointer is connected with the spring winding drum, the spring winding drum is taken up when the hydraulic cylinder piston moves and accordingly drives the pointer to move on the scale plate along the guide groove, and the stroke position of the hydraulic cylinder piston is displayed in real time. The hydraulic cylinder stroke display device can accurately detect the hydraulic cylinder stroke and display the hydraulic cylinder stroke outside a hydraulic cylinder, facilitates observation of an operator and is accurate, reliable, intuitive and convenient to use, production efficiency can be improved, the safety operability of the device is greatly improved, and the detection accuracy of the device is ensured.
Description
Technical field
The present invention relates to a kind of hydraulic cylinder travel display unit, belong to mechanical equipment technical field.
Background technique
Oil hydraulic cylinder operationally, in order to meet the needs of production technology and Automated condtrol, Real-Time Monitoring must be carried out to stroke, generally realized by displacement transducer, be presented on the operation panel of equipment, but in actual production process, often need operator's energy direct vision to the stroke of oil hydraulic cylinder, at present in process of production, accurately can detect hydraulic cylinder travel, the stroke of oil hydraulic cylinder is intuitively shown convenient operation, and person's observation does not also have good solution.
Summary of the invention
For solving the problems referred to above that prior art exists, the present invention will design one accurately can detect hydraulic cylinder travel, and intuitively can be presented at the hydraulic cylinder travel display unit that on oil hydraulic cylinder, convenient operation person observes.
To achieve these goals, technological scheme of the present invention is as follows: a kind of hydraulic cylinder travel display unit, comprise guide rod, draw-wire displacement sensor, leading truck, steel wire, scale, guiding groove, pointer and spring spool, described guide rod is fixed on hydraulic cylinder piston, described draw-wire displacement sensor connects on the guide bar, one end of described steel wire connects on the guide bar by leading truck, the other end is connected on pointer, described pointer is connected with spring spool, described leading truck, scale, guiding groove and spring spool are all fixed on hydraulic cylinder body.
Working principle of the present invention is as follows: hydraulic cylinder travel display unit of the present invention is made up of two-part, and a part is by draw-wire displacement sensor, converts the displacement of hydraulic cylinder piston to electrical signal, operation panel shows hydraulic cylinder travel in real time; Another part is a set of scale pointer mechanical mechanism of design, be made up of guide rod, leading truck, steel wire, scale, guiding groove, pointer and spring spool etc., steel wire one end is by guide rod and leading truck connecting fluid pressure cylinder piston, one end concatenation pointer, pointer linking springs reel, spring spool rolling thereupon during hydraulic cylinder piston motion, thus drive pointer to move on scale along guiding groove, the travel position of display hydraulic cylinder piston in real time.
Compared with prior art, the present invention has following beneficial effect:
The present invention accurately can detect hydraulic cylinder travel, is shown by hydraulic cylinder travel in oil hydraulic cylinder outside, and convenient operation person observes, and accurately and reliably, intuitive and convenient, not only can enhance productivity, and significantly enhances device security operability.The present invention can not only by electrically detecting hydraulic cylinder travel, and by a set of pointer scale mechanism, realize the mechanical detection of hydraulic cylinder travel, this arrangement of mechanism is outside hydraulic cylinder body, simple, intuitive, is very easy to the observation of operator, solves a difficult problem in actual production process, to ensure equipment safe handling and increase work efficiency, all tool is of great significance.Mainly there is following innovative point:
1, achieve the electric of hydraulic cylinder travel and mechanical double check, ensure that the accuracy of stroke detection;
2, novel structure is unique, adopts a kind of pointer scale mechanism, can detect the stroke of oil hydraulic cylinder in real time, accurately and reliably, and intuitive and convenient, the observation of convenient operation person;
3, adopt spring spool structure, utilize the storage of spring energy and release to realize the movement of pointer on scale, reflect the motion of hydraulic cylinder piston with this;
4, unique leading truck and guiding groove design, ensure pointer movement freely, indicating graduation is accurate.
Accompanying drawing explanation
Fig. 1 is parts of the present invention assembling schematic diagram.
Fig. 2 is the A direction view of Fig. 1.
In figure: 1, hydraulic cylinder body, 2, hydraulic cylinder piston, 3, guide rod, 4, draw-wire displacement sensor, 5, leading truck, 6, steel wire, 7, scale, 8, guiding groove, 9, pointer, 10, spring spool.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.As shown in Figure 1-2, guide rod 3 is fixed on hydraulic cylinder piston 2, draw-wire displacement sensor 4 is connected on guide rod 3, steel wire 6 one end is connected on guide rod 3 by leading truck 5, one end is connected on pointer 9, pointer 9 is connected with spring spool 10, and leading truck 5, scale 7, guiding groove 8 and spring spool 10 are fixed on hydraulic cylinder body 1.Hydraulic cylinder travel display unit of the present invention can realize electrically detecting and mechanical detection two kinds of modes.When hydraulic cylinder piston 2 moves, drive guide rod 3 to move, guide rod 3 drives draw-wire displacement sensor 4 and steel wire 6 to move, and draw-wire displacement sensor 4 exports electric signal, and equipment operating panel shows hydraulic cylinder travel, realizes electrically detecting.Steel wire 6 drives pointer 9 to move along guiding groove 8 simultaneously, the stroke of hydraulic cylinder piston 2 can be gone out by direct vision by the scale of scale 9, now spring spool 10 unwrapping wire, stored energy, when hydraulic cylinder piston 2 backhaul, spring spool 10 releases energy, under spring force spiral, pull pointer 9 to move along guiding groove 8, scale 7 indicates stroke.
