Fig. 2 is the partial sectional view on the other direction of this automobile electromagnetic switch over travel digitalized measuring apparatus;
Fig. 3 is the control flow for displaying figure of automobile electromagnetic switch over travel digitalized measuring apparatus of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, automobile electromagnetic switch over travel digitalized measuring apparatus of the present invention, comprise: base plate 3, be vertically set on first iron plate 1 and second iron plate 13 at base plate 3 two ends, be fixed with bakelite plate 2 on first iron plate 1, be provided with V-type bearing 4 between first iron plate 1 and second iron plate 13, elastomeric joint 16 and fixture splice 17 are arranged on the bakelite plate 2, measured workpiece 5(is the automobile electromagnetic switch) lie on the V-type bearing 4, two central electrodes of workpiece 5 contact with fixture splice 17 with elastomeric joint 16 respectively, the opposite side of workpiece 5 is provided with chute 8, has tooth bar 7 on the chute 8, tooth bar 7 is connected by web member 14 with cylinder 15 and tooth bar 7 is carried out push-and-pull, make its front and back slippage on chute 8, driving pinion wheel 10 with hour rack 7 rotates, gear wheel 9 and pinion wheel 10 are fixed on the same axis, angular velocity is identical, gear wheel 9 drives the pinion wheel 11 that is installed on the scrambler 12 and rotates, the pulse of scrambler 12 output respective numbers, be divided into two-way via control circuit and deliver to total kilometres counter and compression travel counter respectively, measure in order to two kinds of strokes to workpiece.The front end of tooth bar 7 is equipped with pushbutton switch 6, is used for controlling the measurement of electromagnetic switch total kilometres, and the measurement of compression travel is controlled by the built-in switch of workpiece 5.
As shown in Figure 3, automobile electromagnetic switch over travel digitalized measuring apparatus of the present invention partly is made up of quantised samples control circuit, counter etc., driven gear rotated when tooth bar 7 moved forward and backward, the gear driven scrambler rotates and the pulse of output respective numbers, and the tooth pitch of tooth bar 7 is that modulus (m) multiply by π, and the mould of tooth bar is 1, tooth pitch=π then, π is an irrational number, can't directly quantize, and now gets the approximate value of π
, this mark is 4/10000ths with the error of π value, can satisfy request for utilization, concrete grammar is: the mould of tooth bar, gear is 1, and pinion wheel 10 is 21 teeth, and gear wheel 9 is 66 teeth, with pinion wheel 10 coaxial installations, pinion wheel 11 is installed on the scrambler 12, and the number of teeth is 15 teeth, when tooth bar 7 drives pinion wheel 10 rotations, gear wheel 9 is with identical rotational speed, because of the gear ratio of gear wheel 9 and pinion wheel 10 is 22 to 7, so pinion wheel 10 revolutions are crossed 1 tooth, then gear wheel 9 turns over
, promptly tooth bar 1 tooth that advances is (approximate
Millimeter), gear wheel 9 changes
Tooth, the arc length of per tooth are 1 millimeter, and the pinion wheel 11 on the scrambler 12 is because with the gear wheel engagement, the arc length of moving 1 tooth of revolution is 1 millimeter, and 15 teeth then are 15 millimeters, and the umber of pulse weekly of scrambler 12 is 1500, tooth bar 7 whenever advances 1 millimeter, then 100 pulses of scrambler 12 outputs.
Automobile electromagnetic switch over travel digitalized measuring apparatus measuring process of the present invention is as follows: after air valve is opened, cylinder 15 promotes tooth bar 7 and moves ahead, after being forwarded to pushbutton switch 6 connections, the total kilometres counter begins counting, when continuing to be forwarded to the built-in switch connection of workpiece 5, the compression travel count table begins counting, when the movable core of electromagnetic switch is pulled to terminal point, two table countings finish, and the numerical value that show this moment is the data that measure.
