The accompanying drawing explanation
The theory diagram that Fig. 1 is tester for moment of mainspring of the present invention;
Fig. 2 is mechanical part structural representation of the present invention;
Fig. 3 is barrel mechanism structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in detail.
With reference to figure 1, tester for moment of mainspring comprises mechanical part and electric part; Mechanical part has been used for transmission and fixing function; Electric part is for the control of upper number of turns and the angle of control step motor, and the output torque of Real-time Collection sensor also realizes the printing of M curve.
As shown in Figure 2, it comprises a stepper motor 1 to wherein said mechanical part structural drawing, and stepper motor 1 is arranged on main guide rail 2, under the manipulation of lifting handle 3, can move up and down along this main guide rail 2; Stepper motor 1 connects winding key 4; Barrel holder 5, for fixing barrel mechanism 6 to be tested, is provided with six barrel pressing plates 7 along even circumferential on the barrel holder, and barrel pressing plate 7, for being pressed in barrel mechanism 6 to be tested, is realized the effect of stationary barrel mechanism 6; After stationary barrel mechanism 6, barrel mechanism 6, barrel holder 5, barrel holder revolving shaft 8, sensor shift fork 9 become one.When stepper motor drives winding key 4 rotations, when winding key drives bar axle 61 rotation in barrel mechanism 6, barrel mechanism 6 is rotation in the opposite direction under the reacting force of clockwork spring 60, after barrel mechanism 6 rotations, meeting drives barrel holder 5, barrel holder turning axle 8 rotates together with sensor shift fork 9, sensor shift fork 9 is pressed on sensor 10, and then sensor 10 acquisition torque signals, exports to analog-to-digital conversion module and carries out analog to digital conversion.Barrel holder fixed pin nail seat 11, for when barrel is installed, guarantees that barrel holder 5 does not rotate, and sensor shift fork 9 does not contact with sensor 10, guarantees that so on the one hand the test initial value is zero, protects on the other hand sensor.
With reference to figure 3, barrel mechanism 6 comprises bar axle 61, barrel 62, clockwork spring 63.During installation, first clockwork spring 63 is coiled in barrel 6, and yielding attachment 631 is hooked on barrel hook 621, then bar axle 61 is passed from the clockwork spring center, and hook in clockwork spring 632 is hooked on bar axle hook 611, the two ends of clockwork spring 63 just are separately fixed on barrel 62 and bar axle 61 like this, because the material of clockwork spring is the metallic elastic material, be shaped as helix, make 61 rotations of bar axle by winding key 4 when stepper motor 1 after, bar axle hook 611 can drive clockwork spring 63 curling generation elastic deformation gradually by hook in clockwork spring 632, clockwork spring 63 can act on barrel hook 621 by yielding attachment 631 because of the elastic force that elastic deformation produces, barrel 62 is rotated.
It is Master control chip that this tester for moment of mainspring is used ARM (STM32F103VET6), by the PWM control mode, gives the stepper motor driver signal, and then makes stepper motor realize tightening or loosening up clockwork spring.The moment values that clockwork spring produces can be by mechanical transmission mechanism as medium, collect voltage signal by strain-gauge transducer and deliver to analog-to-digital conversion module, complete simulating signal (voltage signal), be converted to the digital signal that ARM can identify, thereby the signal collected is processed to computing, can be controlled the demonstration that LED display is carried out real-time moment values and real-time curve afterwards.After measuring end, the printing that also can be measured M curve and measure numerical value by printer, for analyzing or filing.
The course of work:
1, the pin on barrel holder fixed pin nail seat 11 is inserted in the fixed orifice of barrel holder 5 sides, to guarantee that, in the process of mounting bar case structure 6, barrel holder 5 does not rotate, sensor shift fork 9 does not contact with sensor 10.
2, barrel mechanism 6 is placed on barrel holder 5, makes barrel mechanism 6 concentric with the circle of reference on barrel holder 5, tighten barrel pressing plate 7.
3, the rotation and lifting handle 3, and stepper motor 1 will descend along main guide rail 2, make the four directions on bar axle 61 face accurate winding key 4 and enter wherein.
4, the pin on barrel holder fixed pin nail seat 11 is extracted from the fixed orifice of barrel holder 5 sides.
5, by the keyboard on electric control box, set rotating cycle and the angle of stepper motor, press acknowledgement key.
6, the axle of stepper motor 1 drives by winding key 4 number of turns and the angle that bar axle 61 above bar direction rotations set, 6 drive barrel barrel holder revolving shaftes 8 of barrel mechanism and sensor shift fork 9 are with opposite spin, and now sensor shift fork 9 is pressed in sensor 10 sensitive surface.After stepper motor 1 rotates to the number of turns and angle of appointment, stepper motor 1 can be again to put the number of turns and the angle set before the bar direction rotation, until recover the original state of clockwork spring, tighten and loosen the variation of the number of turns in whole process along with clockwork spring, inductor is exported corresponding instant moment immediately, and these instant moments are printed as to curve.
7,, after stepper motor 1 quits work, instrument can point out test process to finish by prompt tone.
8, again the pin on barrel holder fixed pin nail seat 11 is inserted in the fixed orifice of barrel holder 5 sides, rotation and lifting handle 3, take off barrel mechanism, completes test.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
