Description
Technical field
The utility model relates to a kind of hydraulic cylinder travel display device, belongs to mechanical equipment technical field.
Background technology
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 guidance panel of equipment, but in actual production process, often need operator's energy direct vision to the stroke of hydraulic cylinder, at present in process of production, accurately can detect hydraulic cylinder travel, the stroke of 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 utility model will design one accurately can detect hydraulic cylinder travel, and intuitively can be presented at the hydraulic cylinder travel display device that on hydraulic cylinder, convenient operation person observes.
To achieve these goals, the technical solution of the utility model is as follows: a kind of hydraulic cylinder travel display device, comprise guide pole, draw-wire displacement sensor, guide frame, steel wire, scale, gathering sill, pointer and spring spool, described guide pole 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 guide frame, the other end is connected on pointer, described pointer is connected with spring spool, described guide frame, scale, gathering sill and spring spool are all fixed on hydraulic cylinder body.
Principle of work of the present utility model is as follows: hydraulic cylinder travel display device of the present utility model is made up of two parts, a part passes through draw-wire displacement sensor, convert the displacement of hydraulic cylinder piston to electric signal, guidance 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 pole, guide frame, steel wire, scale, gathering sill, pointer and spring spool etc., steel wire one end is by guide pole and guide frame 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 gathering sill, the travel position of display hydraulic cylinder piston in real time.
Compared with prior art, the utility model has following beneficial effect:
The utility model accurately can detect hydraulic cylinder travel, is shown by hydraulic cylinder travel in 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 utility model 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 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 guide frame and gathering sill design, ensure pointer movement freely, indicating graduation is accurate.
Accompanying drawing explanation
Fig. 1 is parts of the present utility model 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 pole, 4, draw-wire displacement sensor, 5, guide frame, 6, steel wire, 7, scale, 8, gathering sill, 9, pointer, 10, spring spool.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.As shown in Figure 1-2, guide pole 3 is fixed on hydraulic cylinder piston 2, draw-wire displacement sensor 4 is connected on guide pole 3, steel wire 6 one end is connected on guide pole 3 by guide frame 5, one end is connected on pointer 9, pointer 9 is connected with spring spool 10, and guide frame 5, scale 7, gathering sill 8 and spring spool 10 are fixed on hydraulic cylinder body 1.Hydraulic cylinder travel display device of the present utility model can realize electrically detecting and mechanical detection two kinds of modes.When hydraulic cylinder piston 2 moves, drive guide pole 3 to move, guide pole 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 gathering sill 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, storage power, when hydraulic cylinder piston 2 backhaul, spring spool 10 releases energy, under spring force spiral, pull pointer 9 to move along gathering sill 8, scale 7 indicates stroke.
