Embodiment
Understand for convenience technology contents of the present utility model, below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
As shown in Figure 1, a kind of two drive apparatus sync detection device that drives, comprise the first motor 11 and the second motor 21, the first driving shaft 12 and the second driving shaft 22, the first PTO 13 and the second PTO 23, the first detected member 14 and the second detected member 24 and signal comparing element 3 that structure is identical, also comprise type and model all consistent the first approach switch 15 and the second approach switch 25 and be correspondingly with it used for respectively supporting the first bracing frame 16 and the second bracing frame 26 that above-mentioned the first approach switch 15 and the second approach switch 25 are installed; Described the first detected member 14 and the second detected member 24 are that end is bolted circular and on the outer peripheral face of annulus circumferential a plurality of cylinders 42 of uniform fixedly welding; Wherein the first motor 11 is delivered to the first PTO 13 by the first driving shaft 12 by power, the first detected member 14 is fixedly mounted on the first driving shaft 12, and the first approach switch 15 is arranged on the first bracing frame 16 and its signals collecting end correspondence is packed in the free end of the cylinder 42 in the first detected member 14 on the first driving shaft 12; Similarly, the second motor 21 is delivered to the second PTO 23 by the second driving shaft 22 by power, the second detected member 24 is fixedly mounted on the second driving shaft 22, and the second approach switch 25 is arranged on the second bracing frame 26 and its signals collecting end correspondence is packed in the free end of the cylinder 42 in the second detected member 24 on the second driving shaft 22; The signal output part of described the first approach switch 15 and described the second approach switch 25 is connected to two of described signal comparing element 3 independently input ends by cable respectively.
As shown in Figures 2 to 4, described the first detected member 14 and the second detected member 24 are made process and are: first according to the diameter of axle of the driving shaft of installation place (i.e. the first driving shaft 12 and the second driving shaft 22), getting this rectangle iron plate 41 of rectangle iron plate 41(adapting with the girth of the corresponding diameter of axle is exactly a rectangular sheet iron in fact, and the length of this rectangle iron plate 41 should be slightly larger than the girth of the shaft part of corresponding driving shaft); Then, at got rectangle iron plate 41 upper surfaces, weld the identical cylinder 42 in a plurality of height, cross section and interval each other, the concrete quantity of the cylinder 42 welding is determined according to the rotating speed of on-the-spot driving shaft, and is respectively equipped with tapped through hole 43 at the two ends of rectangle iron plate 41; During use, by the two ends of rectangle iron plate 41 to curved, curve an annulus, now the lower surface of rectangle iron plate 41 forms the inner circumferential surface of annulus, the upper surface of rectangle iron plate 41 forms the external peripheral surface of annulus, the inner circumferential surface of annulus is attached on the outer peripheral face of driving shaft, between the outer peripheral face of the inner circumferential surface of annulus and corresponding driving shaft, an anti-slip rubber circle 5 is preferably set; Finally, with bolt 44, by described tapped through hole 43, detected member (referring to the first detected member 14 and the second detected member 24) is fixed on driving shaft (referring to the first driving shaft 12 and the second driving shaft 22).
The first detected member 14 and the second detected member 24 are arranged on respectively the first driving shaft 12 and guarantee consistent with the installation site that needs only both on the second driving shaft 22; So in the utility model, be not strict with very much the installation site of detected member on driving shaft, more flexible; The first approach switch 15 and the second approach switch 25 are fixedly mounted on respectively on the first bracing frame 16 and the second bracing frame 26, and the distance of the cylinder 42 on they and detected device is decided by the measurement characteristics of selected approach switch (referring to the first approach switch 15 and the second approach switch 25); The output signal of two approach switchs (referring to the first approach switch 15 and the second approach switch 25) is respectively by the corresponding access of the control cables signal signal input part independently of two on components and parts 3 relatively; By signal comparison components and parts 3, according to field condition, contrast is set, the detection signal whether output is synchronous.
Above-mentioned approach switch (referring to the first approach switch 15 and the second approach switch 25) is also proximity switch, claim again static position switch, its pick-up unit that can be used as a kind of non-contact type is used, and is used for detecting part rotating speed or for frequency conversion counter, variable-frequency pulse generator etc.
In general commercial production place, conventionally all select vortex type proximity switch and capacitive approach switch.Because these two kinds of approach switchs are lower to the requirement condition of environment.When measurand is conductive body maybe can be fixed on an object in metal object time, generally all select vortex type proximity switch, because high, the anti-environmental interference performance of its response frequency is good, applied range, price are lower.If measured object is permeability magnetic material or in order to distinguish while magnet steel being embedded in testee with it at a synkinematic object, should select proximity Hall switch, its price is minimum.No matter select which kind of approach switch, all should note the requirement to indices such as operating voltage, load current, response frequency, detection distances.
The approach switch using can be: passive approach switch, and this switch does not need power supply, by the closure state of magnetic force induction gauge tap; When magnetic or the close switch of irony trigger (being each cylinder 42 in the utility model) magnetic field, and the inner magneticaction control of switch is closed, and feature is not need power supply, contactless, non-maintaining, environmental protection.Also can be vortex type proximity switch, this switch be also inductance approach switch sometimes; It is to utilize conductive body when approaching this and can generate an electromagnetic field approach switch, makes interior of articles produce eddy current; This eddy current reacts to approach switch, and switch internal circuit parameter is changed, and identify thus and have or not conductive body to shift near, and then the on-off of gauge tap; The object that this approach switch can detect must be electric conductor; When there being object (being each cylinder 42 in the utility model) to shift to approach switch, and while being close to certain distance, displacement transducer just has " perception ", and switch just can move, and this distance is cried " detect apart from " conventionally; Detecting apart from different of different approach switchs.So the measurement characteristics that the distance of cylinder 42 ends on the first approach switch 15 and the second approach switch 25 and detected device is possessed by kind and the model of selected approach switch (referring to the first approach switch 15 and the second approach switch 25) decides.
As the cylinder 42 in the detected member in the utility model (referring to the first detected member 14 and the second detected member 24), each cylinder 42(is tested test object) be by certain time interval, shift to one by one approach switch, another ground leaves, and so constantly repeats.Different approach switchs is different to the responding ability of detected object; This response characteristic is called as " response frequency ".So, by the distribution situation of rotating speed and the cylinder in detected member 42 of driving shaft, determine type and the model of the approach switch using, or the type of selected approach switch and model are determined the number of the cylinder 42 in detected member.
Because the bracing frame (referring to the first bracing frame 16 and the second bracing frame 26) of above-mentioned installation approach switch does not all contact with driving shaft, motor (referring to the first motor 11 and the second motor 21) and PTO (referring to the first PTO and the second PTO), so driving shaft, motor and the PTO shock conditions in operational process can not have influence on the measurement result of approach switch.
In the utility model, during entry into service, make the position consistency of the position of the first detected member 14 of described the first approach switch 15 correspondences second detected member 24 corresponding with described the second approach switch 25, if the rotational synchronization of the first driving shaft 12 and the second driving shaft 22, the first approach switch 15 is the same with the frequency of the cylinder detecting 42 of the second approach switch 25 outputs, otherwise, have rotating deviation, the rotation of the first driving shaft 12 and the second driving shaft 22 is asynchronous.
