Embodiment
For this reason, the utility model core is open a kind of approach switch 3 pick-up units, detects the object of distance to realize accurate control.Below, with reference to accompanying drawing, embodiment is described.In addition the utility model content that the embodiment shown in, does not record claim plays any restriction effect.The solution of the utility model that in addition,, the full content of the represented formation of embodiment is not limited to record as claim is necessary.
As shown in Figure 1 to Figure 2, this approach switch pick-up unit, comprise for being arranged on the fixed support 1 on equipment matrix, for being fixed on the detection catch 2 in detected mechanism and being arranged on described fixed support 1 and responding the approach switch 3 of described detection catch 2, wherein, on described fixed support 1, be provided with along the first slide rail 11 and the second slide rail 12 perpendicular to the parallel layout of described fixed support 1 axis direction, and the direction that described the first slide rail 11 and described the second slide rail 12 move along described detection baffle plate is extended, described detection catch 2 is between described the first slide rail 11 and described the second slide rail 12.
While using above-mentioned detection device, the fixed support 1 that is fixed with approach switch 3 is arranged on equipment matrix, detection catch 2 is fixed in detected mechanism and between the first slide rail 11 and the second slide rail 12.In the time that detected mechanism moves, detecting catch 2 can move between the first slide rail 11 and the second slide rail 12, and detect catch 2 in moving process under the effect of the first slide rail 11 and the second slide rail 12 not can with the hypotelorism of approach switch 3, can be too not far away yet, thus reach accurate control and detected the object of distance.
Wherein the first slide rail 11 and the second slide rail 12 can be separately fixed on fixed support 1, form layer structure, detect catch 2 between the first slide rail 11 and the second slide rail 12, as shown in Figure 2.For simplified structure, described the first slide rail 11 and described the second slide rail 12 are integral type structure, and form the first slotted hole 13 between described the first slide rail 11 and described the second slide rail 12, detect catch 2 and move in the first slotted hole 13.Detect catch 2 in order to prevent that hangnail from scratching, the two ends of described the first slotted hole 13 are convex structure.The width of the first slotted hole 13 is slightly wider than detecting catch 2, detects catch 2 and can move freely along the length direction of slotted hole.The length of the first slotted hole 13 is also to determine according to the actual act scope of detected mechanism.
In order to guarantee to detect the stability in catch 2 moving process, described the first slide rail 11 and described second slide rail 12 of integral structure have two groups, lay respectively at the both sides of described approach switch 3, as shown in Figure 1.Described fixed support 1 is for to be made by channel-section steel with the first slide rail 11 and the second slide rail 12, and process is welded and fixed together.
For the convenient approach switch 3 of replacing different size, described approach switch 3 is fixed on described fixed mount by mounting hole.For the convenient position of approach switch 3 on mounting hole of adjusting, described mounting hole is the second slotted hole 14, and the wider cross section of described the second slotted hole 14 is arranged on described detection catch 2 moving directions.
The width of the second slotted hole 14 of fixed support 1 is more bigger than approach switch 3 external diameters, and the general self-locking jack panel of approach switch 3 can be arranged on the second slotted hole 14 positions of fixed support 1.The length of slotted hole determines according to the actual act scope of detected mechanism, if approach switch 3 need to detect object up and down two spacing, approach switch 3 is just arranged in two limit points.The length of slotted hole is generally slightly long to leave the surplus of adjusting than spacing position.
The distance of the first slotted hole 13 to second slotted holes 14 of fixed support 1 is determined according to following principle: fixed support 1 is installed after approach switch 3, and through suitably adjusting, approach switch 3 and the distance detecting between catch 2 are the best distance that detects.
Fixed support 1 can be fixed the place outside detected mechanism, and fixed support 1 installation site keeps relative static with detected mechanism.General recommendations is used channel-section steel to make, and fixed form can be welding, bolt connection etc.
Detecting catch 2 is linked together with detected mechanism.The rear end of detecting catch 2 is two-stage hinge arrangement, i.e. hinge structure.The rear end of detecting catch 2 is used for being fixed on detected mechanism, and fixed form can be welding, bolt connection etc.Use this structure can make detected mechanism keep the front end position location of detecting catch 2 to stablize vibrate, rock etc. in situation.
Further, in technical scheme, fixed support 1 and slotted hole can be made into circular arc, to adapt to the position of the detected mechanism of detecting rotational trajectory.Detect the rear end of catch 2 and also can make three grades or multistage hinge arrangement, reduce to a greater extent detected mechanism vibration, the factor impact such as rock and detect effect.
Detecting the front end of catch 2 is that bar shaped is tabular, and width detects and determines to adapt to approach switch 3, and length is slightly longer than the width of two the first slotted holes 13 of fixed support 1.And this length is in the time that the possible vibration of detected material, the factor such as rock affect, hinge arrangement entirely stretch out and full retracted mode under can not exceed the width of two the first slotted holes 13.
The front end that detects catch 2 goes for the detection of most of form approach switchs 3, and it makes material also can be according to the different different materials of making of the detection principle of approach switch 3.When approach switch 3 is passive type, eddy current type, condenser type, Hall-type etc., detect catch 2 use steel plates and make, when approach switch 3 is photo-electric, pyroelectricity formula etc., detecting catch 2 can be that metal or nonmetal solid material are made.
Use this approach switch pick-up unit, can keep detecting the position of catch 2 and approach switch 3, neither can away from approach switch 3 cause signals collecting less than, can be apart from the too near clashing and breaking approach switch 3 of approach switch 3 yet.And detect catch 2 there is two-stage hinge arrangement, need checkout equipment that the slight situation such as movement, vibration occurs and can not have influence on detection effect.
When approach switch 3 is passive type, eddy current type, condenser type, Hall-type etc., detect catch 2 use steel plates and make, when approach switch 3 is photo-electric, pyroelectricity formula etc., detecting catch 2 can be that metal or nonmetal solid material are made.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple modification of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
