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
Below in conjunction with accompanying drawing, the invention will be further described.
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 the first iron plate 1 and second iron plate 13 at base plate 3 two ends, on the first iron plate 1, be fixed with bakelite plate 2, between the first iron plate 1 and the second iron plate 13, be provided with V-type bearing 4, elastomeric joint 16 and fixture splice 17 are arranged on bakelite plate 2, measured workpiece 5(is automobile electromagnetic switch) lie on 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, on chute 8, there is tooth bar 7, tooth bar 7 is connected by web member 14 with cylinder 15 and tooth bar 7 is carried out to push-and-pull, make its front and back slippage on chute 8, with hour rack 7, drive pinion wheel 10 to rotate, gear wheel 9 and pinion wheel 10 are fixed on same axis, angular velocity is identical, gear wheel 9 drives the pinion wheel 11 being arranged on scrambler 12 to rotate, scrambler 12 is exported the pulse of respective numbers, via control circuit, be divided into two-way and deliver to respectively total kilometres counter and compression travel counter, in order to two of workpiece kinds of strokes are measured.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 is comprised of parts such as quantised samples control circuit, counters, when tooth bar 7 moves forward and backward, driven gear rotates, gear driven scrambler rotates and the pulse of output respective numbers, and the tooth pitch of tooth bar 7 is that modulus (m) is multiplied by π, and the mould of tooth bar is 1, tooth pitch=π, π is irrational number, cannot directly quantize, and now gets the approximate value of π
, this mark is 4/10000ths with the error of π value, can meet 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, coaxially install with pinion wheel 10, pinion wheel 11 is arranged on scrambler 12, and the number of teeth is 15 teeth, when tooth bar 7 drives pinion wheel 10 to rotate, gear wheel 9 is with identical rotational speed, because gear wheel 9 is 22 to 7 with the gear ratio of pinion wheel 10, so pinion wheel 10 often turns over 1 tooth, gear wheel 9 turns over
, tooth bar 1 tooth that advances is (approximate
millimeter), gear wheel 9 turns
tooth, the arc length of per tooth is 1 millimeter, the pinion wheel 11 on scrambler 12 is owing to engaging with gear wheel, the arc length of every rotation 1 tooth is 1 millimeter, and 15 teeth are 15 millimeters, and the umber of pulse weekly of scrambler 12 is 1500, tooth bar 7 often advances 1 millimeter, and scrambler 12 is exported 100 pulses.
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, be forwarded to after pushbutton switch 6 connections, total kilometres counter starts counting, while continuing to be forwarded to the built-in switch connection of workpiece 5, compression travel count table starts counting, when the movable core of electromagnetic switch is pulled to terminal, two table countings finish, and the numerical value now showing is the data that measure.
