Description
Technical field
The utility model relates to oil cylinder position detection technique field, particularly a kind of cylinder position detector.
Background technique
At present, need to monitor the stroke of equipment inner cylinder in the operation process of a lot of machinery, namely such as, lifting board in compression type garbage truck and scraper plate are the stroke by controlling oil cylinder and then the motion both control.Oil cylinder detection device in machinery, traditional approach is mostly on oil cylinder, fuselage, arrange the work that is fitted to each other respectively proximity switch and inducting cell, the detection stroke of this kind of detection device is far away, detection device bulky, and the impurity in machinery easily causes interference to proximity switch, the validity that impact detects.
Model utility content
The purpose of this utility model proposes the cylinder position detector that a kind of volume is little, can avoid impurity interference in testing environment.
For realizing above object, the technical solution adopted in the utility model is: a kind of cylinder position detector, the side of cylinder block arranges guide rail, the guide rod that one end is connected with the end of piston rod coordinates with guide rail and moves along the position that guide rail limits, piston rod and guide rod are parallel to each other, and guide rod and cylinder block arrange inducting cell and the proximity switch of the work that is fitted to each other.
Compared with prior art, there is following technique effect in the utility model: arranges guide rail in the side of cylinder block, a guide rod is placed in guide rail, guide rod and cylinder block are arranged inducting cell and the proximity switch of the work that is fitted to each other, one end of guide rod is connected with the end of cylinder piston rod, when piston rod movement, the position that piston rod will drive guide rod to limit along guide rail is moved, when guide rod moves to inducting cell and proximity switch responds to working zone, proximity switch transmission of signal is to electric control system, cut off oil circuit supply by electric control system and realize oil cylinder stroke location.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail.
A kind of cylinder position detector, the side of cylinder block 10 arranges guide rail 20, the guide rod 30 that one end is connected with the end of piston rod 11 coordinates with guide rail 20 and moves along the position that guide rail 20 limits, piston rod 11 and guide rod 30 are parallel to each other, and guide rod 30 and cylinder block 10 arrange inducting cell 40 and the proximity switch 50 of the work that is fitted to each other.When piston rod 11 moves, the position that piston rod 11 will drive guide rod 30 to limit along guide rail 20 is moved, when the inducting cell 40 on guide rod 30 move to proximity switch 50 respond to working zone time, proximity switch 50 transmission of signal, to electric control system, cuts off oil circuit supply by electric control system and realizes oil cylinder stroke location.Whole detection device is fixed on oil cylinder and carries out, small volume, by the working environment Seal and preservation of whole device isolation with impurity, can avoid impurity interference in testing environment in addition.
As further preferred version, described inducting cell 40 is projection shape and is positioned at two ends to be arranged on guide rod 30, and proximity switch 50 is arranged on cylinder block 10 and is in and inducting cell 40 mobile route anastomotic site place.When the inducting cell 40 of projection shape moves to the sensed position of proximity switch 50 along with guide rod 30, namely electrical system is cut off or Closed control oil circuit, thus realizes the location to oil cylinder stroke.
Further, described cylinder block 10 surface overhangs and has dunnage 60, and proximity switch 50 is placed in dunnage 60.Overhanging out one on the surface of cylinder block 10 for placing the dunnage 60 of proximity switch 50, so just facilitating the installation of proximity switch 50 and fixing.
Preferably, described guide rail 20 is a pipe, and guide rail 20 offers pipe seam 21 away from the side tube wall of cylinder block 10, and on guide rod 30, inducting cell 40 stretches out from described pipe seam 21.The side tube wall of the guide rail 20 of circular tube shaped offers pipe seam 21, inducting cell 40 on guide rod 30 stretches out from pipe seam 21, when guide rod 30 moves in guide rail 20 along with piston rod 11, the pipe seam 21 that namely projection shape inducting cell 40 can be passed through guide rail 20 side is followed guide rod 30 and is moved together, guarantee position between inducting cell 40 and proximity switch 50 close to away from.
Further, described proximity switch 50 is proximity Hall switch, and inducting cell 40 is magnetic projection.Why adopt proximity Hall switch, because proximity Hall switch has the good characteristics such as non-contact electric, low power consumption, long life, response frequency height, in addition, detected object due to proximity Hall switch can only be magnetic bodies, like this inducting cell 40 is set to magnetic bodies, the interference of the object of other material in detection device can be avoided, increase and detect validity.
Preferred, the outer cover of described proximity switch 50 is provided with protecting jacket.Arranging of protecting jacket can avoid other impurity in testing environment to the infringement of proximity switch 50, to extend the working life of proximity switch 50.
