Embodiment
The magnetic force regulating constant tension mechanism of a kind of displacement sensing formula as shown in Figure 1-2, comprise the damping wheel 1, guide wheel 4, tension wheel 13, position-limited wheel 14 and the rotor with salient poles 15 that set gradually, described tension wheel 13 is connected with portable bar 12, and described portable bar 12 stretches into fixed case 6 and is connected with the permanent magnetic plate 11 of magnetic regulator 8 inside being in fixed case 6 inside; Have the energising magnetic sheet 10 of diff-H for magnetic regulator 8 inside above permanent magnetic plate 11 with permanent magnetic plate 11, described magnetic regulator 8 is connected with resistance controller 7; Magnetic regulator 8 top is connected with the set screw 9 through fixed case 6; The displacement pickup 5 being carried out regulating resistance controller 7 resistance by monitoring bar 12 motion is provided with bottom described fixed case 6;
The enamel wire 3 extracted out in coiled strip 2 on damping wheel 1 is successively by damping wheel 1, guide wheel 4, tension wheel 13, position-limited wheel 14, finally be wrapped on rotor with salient poles 15, regulated the coiling forward pull of tension wheel 13 pairs of enamel wires 3 by the resistance of regulating resistance controller 7 and/or set screw 9;
During coiling enamel wire 3, the tension force of enamel wire 3 constantly changes, make portable bar 12 up-and-down movement be connected with tension wheel 13, after displacement pickup 5 detects portable bar 12 up-and-down movement, the resistance of regulating resistance controller 7 is to regulate the electromagnetic force in magnetic regulator 8, thus tension force when regulating the coiling of the tension wheel 13 pairs of enamel wires 3 be connected with magnetic regulator 8 by portable bar 12, realize the constant of enamel wire 3 tension force.
Step and the principle of more detailed adjustment enamel wire 3 tension force 1 are as follows:
(1) coiling forward pull presetting: start control path power supply, resistance controller 7 electric.The resistance of regulating resistance controller 7, obtains initial resistivity value R and initial current I.Initial current I gives electricity to the energising magnetic sheet 10 in magnetic regulator 8, and make to produce initial electromagnetic power F1 between energising magnetic sheet 10 and permanent magnetic plate 11, this F1 is finally acted on enamel wire 3 by portable bar 12 and tension wheel 13, produces initial coiling tension force F2.If this tension force F2 is still excessive or too small, do not reach pre-set value, subsequent adjustment again has two kinds of selections, and one is the resistance continuing regulating resistance controller 7, until obtain satisfied F2; Two is turning adjusting screw 9, and magnetic regulator setting height(from bottom) difference H is changed, and H diminishes, and can widen the gap between energising magnetic sheet 10 and permanent magnetic plate 11, F1 diminishes immediately, and F2 also diminishes thereupon, otherwise then H2 becomes large, and F1 becomes large, and F2 becomes large.
(2) start main power source, rotor with salient poles 15 does uniform rotation under powered attendant-controlled wheelchairs driving, and enamel wire 3 is wound on rotor with salient poles 15 in rectangular shape form.During coiling, coiling radius does cyclical variation between maximum radius R1 and minimum radius R2, and enamel wire 3 walks around four corners continually simultaneously, so the coiling tension force F2 on enamel wire 3 is in variation constantly.When the coiling tension force F2 of enamel wire 3 becomes large, enamel wire 3 is oppressed portable bar 12 by tension wheel 13 and is moved up, displacement pickup 5 monitors portable bar 12 and does to be upwards send signal to resistance controller 7 after positive position is moved, resistance controller 7 increases resistance R, electric current I is reduced, cause electromagnetic force F1 to reduce, thus the coiling tension force on enamel wire 3 is fallen after rise to the tension value of initial setting fast again; Otherwise, when the coiling tension force F2 of enamel wire 3 diminishes, electromagnetic force F1 promotes portable bar 12 and moves down, the portable bar 12 that displacement pickup 5 monitors is done to be downwards send signal to resistance controller 7 after negative position is moved, resistance controller 7 reduces resistance R, electric current I is increased, electromagnetic force F1 is caused to increase, thus the coiling tension force on enamel wire 3 is risen to the tension value of initial setting fast again, so go round and begin again, because the change in displacement of portable bar 12 is fed back to magnetic regulator 8 constantly rapidly, thus ensure that the substantially constant of coiling tension force.
The above embodiment is only that the preferred embodiment of the present invention is described; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that ability those of ordinary skill is made technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
